Erkki Somersalo studied mathematics and theoretical physics at the University of Helsinki, obtaining his PhD in Mathematics in 1986. He visited Indiana University in 1986-1987, and Rensselaer Polytechnic Institute in 1990-1991. In 1993, he joined the Rolf Nevanlinna Institute at the University of Helsinki, where he worked as a researcher until 1995 when became an Associate Professor, and in 1998 a Professor, at the Institute of Mathematics of the Helsinki University of Technology.
In 2008, he moved to Case Western Reserve University, where he is currently a Professor of Mathematics.
The main research activity of Erkki Somersalo is in the field of inverse problems. In particular, he has contributed to applications in biomedical research, developing the theory and applications of imaging modalities based on interaction of material and electromagnetic waves, such as Electrical Impedance Tomography (EIT), Optical Absorption and Scattering Tomography (OAST), Magnetoencephalography (MEG), X-ray Computerized Tomography (CT), and imaging by EM wave scattering.
For more than 30 years, he has pioneered the use of Bayesian statistical methods in inverse problems, and together with the related Uncertainty Quantification (UQ), the Bayesian methods constitute the core of his current work in computational inverse problems. Recently, he has extended the areas of research towards modeling of complex biological systems such as metabolism and interaction of cells with their biochemical environment. Outside the biomedical applications, Erkki Somersalo has contributed to computational electromagnetism, remote sensing, and particle accelerator design.
Development of computational tools for biomedical applications: Imaging, modeling and beyond
Biomedical imaging applications are characterized by scarcity of data in view of the complexity of the target, and high sensitivity to noise in the data, as well as to errors or shortcomings in the mathematical model. It has been demonstrated that the Bayesian computational framework is a rich source of new ideas and solutions to address these problems.
Computational modeling of a complex target of imaging, such as human brain, a breast, or thorax, often requires simplifications in which fine scale details are left out, or the complex and only approximately known geometry is not fully modeled. Likewise, artificial boundaries may be introduced to restrict the computations into a limited region of interest. These model simplifications induce modeling errors that may dramatically deteriorate the inverse estimates, sometimes rendering the images useless. One of Somersalo’s longstanding research interests is to address the various model deficiencies in terms of Bayesian statistical methods. Understanding the statistical nature of the modeling errors makes it possible to develop robust and fast algorithms that allow quite significant simplifications of the forward model without compromising the quality of the estimates.
Another central topic of his research is to develop computationally efficient prior models that in a quantitative way correspond to a qualitative description of the a priori information about the target. One recurrent area of interest in Somersalo’s work is magnetoencephalography (MEG), in which the goal is to estimate the electromagnetic cerebral activity from measurements of the magnetic field outside the head induced by the activity. A particular goal of this research is to improve the estimation of spatiotemporal activity of deep brain regions, corresponding, e.g., to basic brain processes such as consciousness and emotions. Bayesian hierarchical models, combined with anatomical information, seem to provide a tool to improve the existing methods significantly.
Multi-scale modeling, and inverse problems related to multi-scale models, is an arising area of increasing importance, in particular in life sciences. Besides the general methodology of combining models at different scales, Erkki Somersalo is currently working on the methodology related to some particular topics, one being the gas transport through cell membranes. The particular question here is, what the role of specified gas channels in the transport process is, and how can we extract information of the micro-scale processes by using macroscopic measurements. Another important topic of multi-scale nature is the development of models that combine cell level metabolism, electrophysiology, and the supply of nutrient and oxygen by the blood flow in brain tissue.

YAHOO! STRENGTHENS MOBILE STRATEGY, EYES 'MOBILE FIRST' USERS
LAS VEGAS, JANUARY 17, 2007 (STAR) By Alma Buelva - Web portal Yahoo sought to carve out a role for itself in last week’s Consumer Electronic Show (CES) as a major provider of content in a growing array of digital devices.
Yahoo finds to its advantage the way many non-PC products – from mobile phones and PDAs to television and even car systems – are also becoming conduits of digital content. Against this backdrop, the Sunnyvale, California-based company launched during the CES its version 2.0 of Yahoo Go for Mobile that delivers more Internet services, including an entirely new search service called oneSearch to mobile and IP devices.
The one-year-old Yahoo Go for Mobile lets users access an integrated suite of services, including Yahoo Mail, Yahoo Search, Yahoo Photos, Yahoo Calendar, and Yahoo Address book, among others, using their mobile phones. It is seamlessly synchronized to a Yahoo ID that can be accessed on a PC (or TV) as well.
There are at present around 500 million Yahoo users accessing their Yahoo accounts mostly from computers. By extending the company’s Yahoo Go vision and strategy, users will be able to connect to the Internet using the medium they really care about, says Marco Boerries, Yahoo senior vice president for Connected Life. That device is the mobile phone.
"For the first time, the Internet now fits on your phone. In the last 10 years, the industry tried to squeeze the Internet to the phone. Yahoo Go is the Internet in your pocket," adds Boerries.
Based on latest industry estimates, there are one billion PCs in the world and approximately two billion cellphones. The latter has reached unprecedented growth with 25 mobile phones created every second around the world today, compared to only four human live births per second.
Yahoo and mobile phone manufacturers say at least 50 percent of Internet users outside the United States or those in the developing markets may never use a PC and will access or have accessed the Internet for the first time using a mobile phone. Addressing the needs of this possible new segment of "mobile first" users is key to the Yahoo Go strategy.
"The global mobile phone-to-PC ratio is 12:1 but we’re seeing that it’s even more than that in Asia," says David Ko, vice president and general manager of Yahoo Connected Life in Asia. "In emerging markets, people connect to the Internet using their mobile phones so we are taking what we learned from the PC space and applying them now to the mobile world."
For the Internet to go airborne, Yahoo has forged unprecedented partnership with competing major mobile phone manufacturers Motorola, Nokia and Samsung.
Ed Zander, chairman and CEO of Motorola, and keynote speaker during the CES, describes the Internet on a mobile phone a "cool experience… that allows the Internet to follow you."
Yahoo’s mobile phone partners will preload Yahoo Go for Mobile on their newer devices. Consumers can also download the application to their compatible devices, says Ko, adding that they expect Yahoo Go for Mobile 2.0 to be available in 400 devices by the end of 2007.
Yahoo also has partnerships with over 80 mobile operators in 40 countries to distribute its mobile services to consumers. It has partnered with mobile service operators Globe Telecom and Smart.
"We have major partnerships for Connected Life in Asia where mobile devices are so pervasive. OEMs and operators see big value in partnering with us to drive data (revenue)," says Ko.
Yahoo’s Connected Life group includes the company’s mobile, co-branded broadband, digital home and PC client services, and Yahoo’s strategic partnerships with companies, including AT&T, BT, Cingular, Nokia and Motorola. This includes the Yahoo Go suite of services, too.

Teldat: Important Considerations When Shopping for a Home Router
Whether you want to upgrade or set up a new home network, shopping for a reliable wireless router is not an easy task because you need to findone that can be easily configured and used. Many WiFi providers brag about the bandwidth, AC, Smart Connect, QoS, Beamforming, and MU-MIMO, but there are basic things you need to know. Always remember not to go below AC1200 for the bandwidth and your wireless router should always be dual-band or more. Your smart home needs stability, speed, and security most especially for increasing number of devices that are connected.
A dual-band wireless router means having two frequencies, allowing you to see two or more wireless networks at home with different names and different passwords. When signing up with an internet service provider, there is usually an equipment rental fee and some offer the equipment for free into the internet package. It is more cost-effective to purchase your own equipment if you are in the United States and you’re planning to keep the same network. You can check different routers companies in the market today and compare the rates and features of their home wireless networks, and even though you have a free router, it is best to have your own wireless router that can provide a better performance and speed. Buying your equipment can save you cash and it can give you more options and better control. The standards for wireless technology have changed over the last ten years, and most newer smartphones, tablets, and laptops use the newer standards, 802.11ac, with faster speeds.

Printed circuit board assembly is the process of connecting electronic components to a rigid, flat board to create a working circuit. PCB assembly has two types: surface mount and through-hole construction.
The leads of through-hole construction are pushed into the board through holes and attached to the pads on the other side through soldering. This can be done manually or with mounting machines. From the 1950s, the through-hole method has been used to replace point-to-point construction until surface mounting became widespread in the 1980s.
Surface Mount Construction
In surface mount construction, the electronic components have direct connections to the surface of the board. The surface mount components are really smaller than those of the through-hole construction because their leads are smaller or they do not have leads at all. They often use flat contacts, solder balls, or pins to replace the leads. This can be an advantage of surface mount over through-hole components. Aside from that, surface mount can have a lot more connection and they have much simpler and quicker assembly. This construction also allows components to be assembled on either side of the board. In general, they are also less expensive that through-hole components.
Although surface mount components are more popular, through-hole construction is still used today. Some components are only available for through-hole and vice versa.
Printed Circuit Board Assembly Services
Oftentimes, PCB assembly is outsourced by manufacturers to a specialist company because setting up a PCB unit is quite an investment. There are lots of small components needed to complete a PCB.
In general, small and medium-sized firms contract electronics specialist companies to create their PCB units. There are some advantages in contracting the services of a specialist company. These are:
1. Save Investment and Labor Costs
Normally, the capital investment in printed circuit board assembly unit is quite high. A manufacturing firm could simply contract out these expenses and save a lot of money. This money can be used to set up their operations, manage inventory, upgrade and maintain their facilities, hire labor, etc.
2. Take Advantage of Specialized Services
An electronics contract company has limited services, but they probably specialize in these services. For example, a contract company has a dedicated work force and a system to look out after their PCB projects. Doing this guarantees specialized services that adhere to up-to-date industry standards.
3. Focus on Basic Skills
The manufacturing company can now focus on their core expertise if they contract out other tasks to a third company. They can spend more efforts in developing their brand and intensifying their marketing and sales network.
When selecting a firm to contract out the PCB assembly, it is crucial to make a knowledgeable decision.
Here are some of the things to be considered when selecting third party PCB services:
1. The most important thing to consider is to make sure the firm has the latest dual in-line and surface mount technologies. These are the most up-to-date standards in the PCB industry.
2. Since most electronic devices have become smaller, it is important to incorporate multi-layer printed circuit boards. Therefore, the chosen firm must be able to produce printed circuit boards with eight layers or more if necessary.
3. Other details to keep in mind include the capacity to utilize a range of conductive elements to fit the company’s electrical circuit requirements. Moreover, secondary in-line operations like ball grid array (BGA) need to be checked. Bonding services must also be provided by the third party firm.
4. It is also important to make sure that the third party PCB assembly firm has complied for RoHS services and uses only UL-listed products to adhere to environment-friendly standards.


Did you know that there are over 420 million off-grid solar panel users as of 2020? But why is the solar sector rapidly developing over the past decade? Grounding off-grid solar systems are very crucial for various reasons.
Grounding your PV installations can help prevent fires and unintentional shocks. It also ensures voltage transients.
In this article, we will talk about grounding and its importance for off-grid solar systems.
What is Grounding?
Grounding your solar systems is crucial, especially if you live in an area that experiences lightning storms. There are two main types of grounding; chassis, or otherwise known as mechanical and electrical. These two types of grounding are different from each other and thus must be understood properly.
In this type of grounding, all the metallic objects that do not carry current are bonded together and then to the earth. These metallic objects include the solar module frame, the backplate, the battery enclosure, array mounting structure, among many others.
This type of grounding is done primarily for safety reasons. Doing chassis grounding prevents potential build-up on a metal object that may cause a shock during contact. Since the voltage is only the potential difference between some potential and ground potential, it is recommendable to do a mechanical ground or chassis ground on the system. This will help get rid of the difference.
The video below explains, why earth grounding is a must.
This type of grounding happens when any conductors that carry current are connected to the grounding system and then to the actual earth. Grounding the electrical system is vital not only for safety but also for electrical transient purposes.
Experts highly recommend connecting one conductor that carries current as close as possible to the battery in battery systems. This is because the battery is the largest DC source of power.
An In-Depth Look Into Electrical Grounds for Off-Grid Solar Systems
Here is additional information on electrical grounds and their benefit.
Load Requirements and Electrical Grounds
Electrical grounds are essential for load requirements. For some loads, like the cathodic protection systems, this is pretty obvious since a reverse process via impress current is used to overpower the pipeline’s naturally occurring ground.
For this reverse process, an electrical ground is required. This is also to increase the life of the system. Should there be excess earth voltage on the pipeline, the pipe coatings may suffer irreparable damages. Understanding the nature of electrical ground can go a long way.
Charge Controllers and Electrical Grounds
Many electrical devices and charge controllers in off-grid systems with transient protection need a grounded conductor to function properly. Put, for the system to work properly, both lines must be connected properly. In case of over-voltage incidents caused by a natural external factor such as lightning, surge arrestors are there to protect the system.
Most surge arrestors use a grounded conductor to help shut or divert the transient. Take note that most of the controllers with grounded conductors are labeled either positive or negative ground.
Mobile Systems and Electrical Grounds
For mobile systems, you can use circuit breakers, fuses, and switches with electrical grounds. More often than not, you need a floating ground in both mobile systems and off-shore platforms. This is because of the nature of the system’s requirements.
Experts still advise that mobile applications should have a common conductor or grounded conductor connected to the actual earth. Because of this reason, the chassis of cars and other vehicles are commonly used as an electrical ground. However, this is not as effective as using the actual earth as the ground. Even so, it still provides a certain degree of safety.
If you want to ground your solar systems, you need to know the difference between chassis and electrical grounds. We hope that this article has given you some insight and knowledge about grounding in off-grid solar systems.


Last Friday (July 19th) we prepared for our mission to Mars. First we looked up vocabulary words. The most important words were aphelion, concentric, and Hohmann Transfer. We went outside and created a replica (sort-of) of the Earth’s and Mar’s orbit around the sun. Their orbits are concentric. We also learned that it takes Mars almost 2 years to complete it’s orbit. In order to travel between the planets, the planet of origin must be at the point of aphelion, which means it’s the furthest away from the sun. To travel you have to use the Hohmann Transfer, it allows you to travel between two circular orbits.
Our second activity was a communication game.
There were 3 roles, astronaut, mission control and radio signal. Mission control had to build something out of legos and take a picture so they can remember what they built. The radio signal isn’t suppose to see it. Mission control takes it apart and gives the parts to the astronaut. Mission control has to tell the radio signal directions one by one so the radio signal can tell the astronaut. The astronaut can not ask the radio signal questions. The astronaut can ask the radio signal to relay a message back to mission control. My role was the astronaut. Overall it was easy to build my LEGO creation, but one difficult thing was that I couldn’t ask the radio signal questions (and get a response from them).

- GICS Intrusion Detection Datasets
- Stephane Mocanu
- Context These datasets were generated for the evaluation of cybersecurity measures in the context of industrial control systems (ICS). An ICS is a set of devices (electrical, mechanical, hydraulic,. . . ) whose interaction controls the behavior of a physical process in order to achieve an industrial objective (manufacturing, transportation of matter and energy, etc.). ICSs serve as the backbone of several critical infrastructures that provide facilities for the generation and distribution of ele ctricity, water treatment and supply, railway transportation networks, and manufacturing applications. Due to their criticality, failures in these systems, whether of accidental or intentional origins, can lead to significant human and economic loss. The recent history of ICSs is that of an ever-growing convergence with classical information technology (IT) systems. In an effort to drive down costs and provide stakeholders, engineers and operators with seamless access to the industrial plants, ICSs are nowadays interconnected with the Internet and have adopted off-the-shelf IT technology such as TCP/IP networking, standard computer architectures, and common operating systems. Concurrently, many of the security vulnerabilities which marred IT systems have been exported to ICSs. Thus, if such systems were once considered secure because of their isolation, their use of proprietary protocols and peculiar architectures, this is no longer the case as witnessed by the growing number of increasingly sophisticated cybersecurity incidents in the last decades. As a result, nation-states, organizations, and industries have become sensitive to the security threats of ICSs, and have been adamant in their call for the development of adequate security measures to protect ICSs from security breaches. One of the key aspects which distinguish an ICS from classical IT systems is the presence of a physical process. This has lead to the apparition of a new class of novel threats which target the physical process. These datasets contain instances of such attacks and can be used to evaluate the efficiency of security measures in protecting an ICS against targeted attacks. Content These datasets include network traces collected at the ENSE3 GICS platform for the purposes of evaluating an intrusion detection system (IDS) for ICS. An IDS is a system which monitors a system in order to automatically detect security breaches. The network traces capture the behavior of an ICS test bed under attacks targeting the physical process. The test bed is implemented in GICS and is comprised of several controllers (Schneider M340/M580, Wago IPC-C6, Siemens, etc.) along with supervisory machines, engineering workstations and human machine interfaces (HMIs). Each controller sends commands and receives sensor information, via I/O interface cards, from a real-time OpenModelica simulation of a complex physical process representing a complex chemical plant. The traces contain, among other protocols, Modbus traffic carrying attacks violating the specifications of the underlying physical process. This is performed by sending a sequence of Modbus commands from workstations to controllers running the control logics which steer the process. Two types of attacks are contained in these datasets. The first type of attacks violates qualitative temporal constraints on the behavior of the physical process. Examples of such attacks include opening simultaneously two valves or stopping a motor before its due time. The second type of attacks violates quantitative temporal constraints. For example, the traces include attacks that wear a valve by quickly opening and closing it. The contents of the datasets is as follows: • One capture free from attacks and containing only legitimate traffic (capture16) • Four captures containing attacks (capture17, capture18, capure19, capture20)> ... ...

Requesting data isn’t harassment, and refusing to share data isn’t science


What is firmware
Firmware is the low level software in integrated circuits that controls how a certain piece of hardware should work.
In most cases you will have to use Windows and the correct software from the vendor to update you device firmware, this is important as bug fixes or features could be added to your device directly from the vendor.
On Linux there is fwupd that allows to update devices firmware, that the vendor added support for, there is a list of supported devices and user documentation.
pamac install fwupd
pamac install fwupd-efi
Pamac does not support firmware updates, alternatively you can install gnome-firmware as your firmware tool with a user interface, that also comes as a default with our Gnome edition.
pamac install gnome-firmware


Thync is new impressive technology, that promises to help its users “conquer life” by allowing them to change their mood on demand. Although it sounds like science fiction, the company expects to receive FDA approval by end of 2015. Researchers today try to improve our bodies and extend the limits of our consciousness in many ways. But do you know what’s the reason for this?
Why do scientists try to enhance our minds?
It’s sure, that the undying motivation of homo sapiens spices to know more, to get further, to speed up its own evolution and expand the inherited functions of human mind, plays the role here. However, it’s not just that. The cognitive enhancement research has great potential to assist us in future eradication of many neurological, psychiatric and psychological diseases, such as various types of dementia and depression, epilepsy, Parkinson’s disease or in brain stroke rehabilitation. We expect them to come either in the form of powerful diagnostic tools or as next generation of highly effective therapies.
Most of currently active cognitive enhancement research can be identified by methods (or tools), via which researchers try to modify cognitive processes of interest, like emotional reactions (e.g. aggression) or processing of sensory information (e.g. pain). Three main approaches tested for their effectiveness are: electrical (non-invasive) enhancements, pharmacological enhancements and physical (invasive) enhancements. The Thync technology works on principles of cognitive enhancement by electrical stimuli. How strong are these approaches? Is the research on electrical cognitive enhancement the broadest? What about chemical and physical ways of enhancing our brains?
The numbers of publications regarding cognitive enhancement are promising. Search for publications yelled 598 publications about pharmacological cognitive enhancements, 37 about physical and 23 about electrical cognitive enhancements. We can see an evident positive trend in the research focused on chemical brain enhancement. Looking at citations, we can observe an interesting drop in 2012 followed by a peak in citations of electrical enhancement research. This was probably caused by legislation change in USA and thus, research funding uncertainty in late 2011. The number of citations for chemical and physical cognitive enhancement are rising at steady rate.
The top publication on electrical cognitive enhancement with 14 citations is 6 years old and its title is “Cognitive enhancement with central thalamic electrical stimulation.” Looking at the states with the highest number of published papers, we can see that USA is on the first place with 742 publications. This which is four times the number of publication in the UK, on second place (185). The biggest contribution as an author in the research about cognitive enhancement has Philip D. Harvey with 17 publication, he examines the ways of cognitive enhancement through chemicals. The biggest number of studies was published in the journal Neuropharmacology (84) followed by journal Psychopharmacology (45).
From this data, we can see that the research is focused mostly on development of active drugs, enhancing our brains. Thync is working within the area which is explored the least. They can bring new findings to research of the brain enhancement and find a way which is not as harmful as some medications can be. On the other hand, the lack of research describing side effects of long-term electric stimulation of brain and emotional states manipulation is rather alarming.
Simplified, yet standardized, communication of relevant scientific knowledge, is the core value of team @ SciCurve.com. We communicate global state of findings from life sciences research. Our aim is to bring trends in science closer to general public, researchers and businesses. If you would like to engage in any kind of cooperation with us, please contact us at: email@example.com

The simulation of human intelligence in machines is referred to as AI (artificial intelligence). This broad field of computer science is poised to transform marketing jobs and the industry in a variety of ways.
In the last four years, the number of businesses adopting artificial intelligence has increased by more than 270%, and the global AI market is expected to reach $267 billion by 2027. This increase is not surprising, especially when you consider all the advantages of implementing AI technology in marketing.
Marketing teams will be able to automate certain cognitive tasks with AI-powered tools. They will also be able to identify current trends and predict future trends, ensuring the success of their marketing campaigns. These are just a few of the ways artificial intelligence will influence marketing strategies. Continue reading to learn about 8 more ways AI will impact the future of marketing.
What exactly is artificial intelligence (AI)?
Artificial intelligence (AI) is a broad field of computer science concerned with the development of intelligent machines capable of performing tasks that would normally require human intelligence. Artificial intelligence, in its most basic form, is a field that combines computer science and large datasets to solve problems. It also includes the subfields of machine learning and deep learning, which are frequently used when discussing artificial intelligence. In these fields, AI algorithms are used to create expert systems that make predictions or classifications based on input data.
- Content Creation
Content creation is one of the most significant ways AI will impact marketing in the future. AI has spawned a new field known as content intelligence, in which AI tools provide data-driven insights and feedback to content creators. This means that by establishing a continuous feedback loop, marketers can improve their content creation efforts and achieve greater success.
Here are a few ways AI is likely to have a positive impact on content creation:
- Create optimized social media posts quickly.
- Create data-driven blog posts to improve your rankings.
- Converting emails and website copy that is personalized
- A/B test landing pages for the best results.
- Conduct thorough keyword research
This is fantastic news for beginners who are unsure of how they are doing with their content creation. AI makes it easier to determine what works and replicates the process for optimal content marketing results. Manual content creation, as any marketer will tell you, is not only a time-consuming process, but it can also be overwhelming, especially when you don’t see the desired results.
AI will assist in content profiling, topic inspiration, content accuracy, and other areas to make the content creation process easier and more effective by providing data-driven feedback while creating content. For example, an AI writing tool like Simplified makes it easier to create highly personalized content that can help boost your marketing efforts.
- Predictive Analytics
Another area where artificial intelligence will change the future of marketing is predictive analytics. AI will better equip marketers to predict future behavior, allowing them to create more effective marketing strategies and products.
Leading online course platforms, for example, are very likely to integrate AI so that instructors can better understand what students are doing in their courses and how to improve student engagement. This will result in better online courses overall, as well as more private label course marketplaces with well-optimized educational assets for sale.
The most advanced AI technologies will be able to use algorithms to analyze massive amounts of data to optimize toward a specific goal. They will, in essence, be “prediction” machines, and as they optimize, the machines will learn and find ways to improve their results. You will be able to drive marketing success in a variety of ways with AI-powered analytics, such as:
- Figure out what’s right (or wrong) with your website (load speed and other technical issues) or other marketing platforms.
- Webinar platforms will be able to predict and comprehend audience disengagement.
- Improve your lead scoring process to find the right potential customers.
- Learn about your main competitors.
- Predict customer behavior, such as the specific products your target audience wishes to purchase.
These are some of the various ways in which artificial intelligence will eventually take over predictive analytics. Of course, there are numerous other applications for AI in predictive analytics, but the main ones will be to discover insights, make predictions, and unify your data.
- Better advertisements
As previously stated, artificial intelligence understands what customers want, so it can easily uncover trends and customer insights to improve advertising efforts. For example, AI programs can use your marketing language and tone to write headlines, create ads, and push notifications. A good article on PPC lead generation tips for a profitable campaign can be found here.
Even more importantly, artificial intelligence tools can change parts of advertisements to personalize them for different types of audiences. AI can accomplish this by including different text, music, images, and so on to cater to the tastes and preferences of a specific segment of the audience. In short, future AI programs will most likely be able to create advertisements that are far more effective than those created by humans.
Listed below are some of the use cases for AI in advertising:
- Discover new advertising channels that your competitors are not currently using.
- Use artificial intelligence (AI) tools on a variety of ad platforms to optimize budget, targeting, and ad delivery.
- Use artificial intelligence marketing platforms for self-serve media purchasing.
- Use machine learning algorithms to determine the best layout, copywriting, targeting, bids, and so on for your PPC campaign.
These are just a few of the ways future marketers will use artificial intelligence to transform the advertising industry at all levels.
- Product suggestions
Artificial intelligence, using Machine Learning, will also aid in the improvement of online product recommendations. With the right AI tools, marketers will be able to make more accurate and timely predictions about which products their customers will purchase.
AI-powered recommendation engines will make personalized recommendations based on each customer’s behavior and preferences. Many businesses are already experimenting with AI-powered product recommendations in eCommerce, and most of them are reaping significant benefits, particularly in terms of their bottom line.
The most notable example is Amazon, a platform that derives up to a third of its revenue from such recommendations. Here are some examples of how an AI-powered product recommendation system can help your company grow:
Product recommendations benefit both the customer and the company. It’s especially important in eCommerce, and it’s the reason why some companies sell so much more online than others.
Just keep in mind that selecting the right recommendation engines is critical because they must be able to process large amounts of customer data with high accuracy. In order to provide accurate and timely personalized product recommendations, they should also be able to track and profile millions of customers in real time. This is critical in modern commerce because 80% of customers are more likely to buy from a company that provides personalized experiences and product recommendations.
- Improved customer service
Chatbots use artificial intelligence to have real-time conversations with users. This is an excellent way for brands to establish credibility and increase engagement, and it is yet another way AI will improve marketing and customer loyalty in the future.
Even when customer service representatives are unavailable, a chatbot can respond to online visitors’ needs around the clock. There are numerous methods for using chatbots to improve customer service in your business, and each method has numerous advantages.
- AI assists you in better understanding your customers.
- AI makes it easier to make real-time decisions based on the most up-to-date data (such as when a customer is having an issue in their current interaction with your business)
- AI can use predictive analytics to provide real-time actionable insights and assist in guiding interactions between businesses and their customers.
- AI enables hyper-personalization to provide users with customer service content that is specifically tailored to their needs.
Customer service via chatbot is currently the most popular artificial intelligence application (73%), closely followed by marketing and sales (59%). This trend is expected to continue, and successful companies are already implementing it to ensure their long-term success.
- Virtual and augmented reality
Artificial intelligence (AI) has already begun to aid the growth of augmented reality (AR) and virtual reality (VR) (VR). In the future, Artificial Intelligence Marketing will improve digital marketing using these realities by allowing customers to shop for products and customize them in any way they want.
For example, a customer may try on different colors of the same item while shopping for dresses to see which one looks best. When shopping for a car, a user may examine the features or even take a virtual test drive to get a sense of the vehicle’s maneuverability.
This type of technology could also have a significant impact on platforms such as YouTube, further immersing users in the content. Not only will this increase watch time and brand affinity for those who embrace it, but it’s also likely to be a better way to earn extra money from YouTube. Other ways AR and VR technologies can be used to improve marketing efforts include:
- Make the in-store experience fun and innovative
- Increase customer interaction.
- Increase the level of online engagement
- Improve the overall customer experience
Many brands have begun to use augmented and virtual reality as marketing tools to help them provide a unique shopping experience to customers, and if you want to find new and unique ways of attracting customers, promoting your products, and increasing sales, you should consider doing the same.
- Email Optimization
AI systems improve the effectiveness of email marketing in two ways: by increasing revenue and decreasing costs. AI-powered email marketing tools can assist in increasing open rates and click rates (among other metrics), thereby making your email marketing campaigns more successful and profitable.
The same tools can make it exponentially easier to create campaigns that never fail, reducing the time it takes your team to produce results for your email marketing activities. Finally, you reduce costs while increasing revenue, which is every marketer’s dream.
Here are some ways AI can help you improve the effectiveness of your email marketing:
- Artificial intelligence can create email subject lines on its own.
- It can tailor the content of your emails to different recipients.
- Using historical data, AI can also restructure your email campaigns.
- AI will allow you to optimize send times for maximum engagement.
- AI can quickly and easily clean up your contacts to improve the health of your email list.
If any of the above use cases apply to you, then AI-powered email marketing technology could be extremely beneficial to your company.
The bottom line is that you will be able to create optimized email campaigns using artificial intelligence marketing, from writing smarter and more personalized emails and newsletters to improving deliverability and optimizing your email outreach efforts.
- Voice Search
Voice search is the final item on our list of the eight ways AI will change marketing in the future, but it is far from the least important. With voice search becoming increasingly popular, it’s not surprising that artificial intelligence (AI) is being used to improve the way people search online.
There are numerous predictions for the impact of voice search in the coming years, and one thing is certain: artificial intelligence will play a significant role in how these changes are implemented.
Voice searches, for example, are more likely to have action-oriented intent. This leads to informational or transactional searches, which can be extremely beneficial to businesses with strong SEO. Voice search AI systems are already having an impact on the SEO landscape, and there are new technological innovations fueling the rise of searches conducted via voice control. The most difficult challenge for most marketers right now is figuring out how to effectively optimize SEO while also preparing for a future of AI-powered voice search.
This could include a significant change in the type of content produced by web pages. This includes incorporating many long-tail keywords into web content to compete with voice searches. If you want to optimize your web pages or web design, here is an article about digital marketing agencies that can assist you.
Experience the future of AI in marketing
We’ve come to the end of this article on the 8 ways artificial intelligence is changing the future of marketing. Businesses must now decide whether they want to maintain their competitive edge by incorporating these changes into their digital marketing strategies.
From lead generation to content creation, marketing, sales, and customer service, incorporating AI into your future marketing strategies will benefit every aspect of your business. This is an excellent time to begin experimenting with artificial intelligence marketing. Begin your journey with a powerful chatbot.


Nozomi Networks protects critical infrastructure from cyber attacks
18 May 2016
Andrea Carcano, Co-founder & CEO
Our Critical Infrastructure is labelled as such because we depend on it for everyday services. It includes our electric grid, power generation, transportation, Oil & Gas infrastructure, and so much more. At the heart of this strategic infrastructure are industrial control system (ICS) networks that orchestrate all processes and machinery necessary to run it. In the past decade, these networks have converged with traditional IT to leverage common hardware and protocols, and the better economics that come with them. Convergence increased vulnerability of these networks, creating the need for increased cyber security to move beyond the traditional IT boundary to include ICS networks. In addition, new government regulations are being put in place and enforced across the globe to strengthen cyber security in critical infrastructure sectors.
To stay ahead of these challenges, the security experts at Nozomi Networks developed the SCADAguardian solution specifically to protect critical assets in industrial control networks from hackers and cyber attacks.
SCADAguardian connects to an ICS network non-intrusively or passively to ensure that the system and its desired performance is not affected. It then learns the behaviour of all devices in the network, creating a tailored security profile to continuously monitor for suspicious network behaviour and anomalous traffic.
When a suspicious event occurs, SCADAguardian alerts users in real time so that the appropriate remedial actions can be taken in a timely fashion. The solution supports and understands a comprehensive suite of industrial protocols allowing it to not only detect a network issue, but to provide analytics on the specific industrial device that could be compromised on the network.
SCADAguardian is a proven solution has been deployed in some of the largest industrial installations around the world serving various key industries. To learn how you can improve your cybersecurity, contact firstname.lastname@example.org or visit http://nozominetworks.com.

Interactive analysis notebook environments promise to streamline genomics research through interleaving text, multimedia, and executable code into unified, sharable, reproducible “research narratives.” However, current notebook systems require programming knowledge, limiting their wider adoption by the research community. We have developed the GenePattern Notebook environment (http://www.genepattern-notebook.org), to our knowledge the first system to integrate the dynamic capabilities of notebook systems with an investigator-focused, easy-to-use interface that provides access to hundreds of genomic tools without the need to write code.
The ongoing explosion of “omics” datasets and the promise of scientific discovery arising from their analysis have given rise to software systems that aim to provide easy access to advanced methods for nonprogramming scientists. These “bioinformatics tool aggregation portals,” e.g., Galaxy (
), also provide for the creation and encapsulation of analytic workflows, transparent access to scalable compute resources, and removal of software installation and implementation concerns from the scientific user.
Alternatively, analysis notebook environments, inspired by the “literate programming” philosophy (
), integrate the exposition of a scientific project with the associated code. They aim to create an “executable document” that ideally serves as a complete description of a research project and which could also be run to reproduce the author's results. Examples include SWEAVE (
Each of these two types of system brings significant value to its targeted user base yet has limitations that prevent wider adoption. Notebook environments model their interface around the annotation of sections of code, and therefore assume that the user is fluent in a programming language such as Python or R. Bioinformatics tool aggregation portals successfully remove the requirement for coding expertise but to date have had limited ability to incorporate the variety of rich text and media formats required to represent the full scientific narrative surrounding each analysis step.
We have developed GenePattern Notebook (Figure 1), an environment that integrates the capabilities of both types of system, allowing users to incorporate encapsulated analysis tools, complete with their user-friendly interface, from a bioinformatics aggregation portal into an interactive analysis notebook. The environment is based on two long-standing software projects: the GenePattern platform for integrative genomics and the Jupyter Notebook environment for interactive computing.
GenePattern (www.genepattern.org), first released in 2004, consists of a repository of hundreds of bioinformatics analysis and visualization methods (“modules”), as well as utilities for data formatting, preprocessing, and other auxiliary functions that provide important “glue” between analysis steps. The user interface is point and click with no programming required. The public GenePattern server, hosted at www.genepattern.org since 2008, has over 40,000 registered users and runs 2,000–5,000 analysis jobs per week. Additional public servers are available at Indiana University (gp.indiana.edu/gp) and the Garvan Institute (pwbc.garvan.org.au/gp). The software has also been downloaded for local installation by over 17,000 bioinformatics core facilities, research laboratories, and individual scientists.
The Jupyter Notebook environment (www.jupyter.org) provides a laboratory notebook metaphor in which researchers build a step-by-step scientific narrative out of “cells” that interleaves code, formatted text, mathematical formulae, plots, and multimedia. The resulting notebooks can be shared, edited, executed, and published as complete encapsulations of in silico research.
The GenePattern Notebook functionality takes the Jupyter Notebook interface one step further, adding analysis, login, and rich text input components that present the GenePattern interface to provide code-free analysis and visualization (Figure S1). All cell types interact seamlessly with existing Jupyter cell types. Within a Python code cell, programming users can easily reference analysis results from a previous GenePattern analysis cell, and in a GenePattern analysis cell, programmers can use Python variables as inputs.
We integrated GenePattern with Jupyter through the use of Jupyter's ipywidgets package, which provides a framework for the creation of new user interface objects within Jupyter Notebooks, and GenePattern's Web services interface, which exposes all of the functionality of GenePattern (e.g., searching for and obtaining module information or querying for the execution status of an analysis) to programmatic access. This combination is a design pattern that has general applicability to the class of Web service-based tools, and the Jupyter development team is incorporating our approach into the currently evolving design of the Jupyter interfaces for graphical input (Dr. Fernando Perez, personal communication, September 26, 2016).
To promote the development and dissemination of GenePattern Notebooks with minimal installation requirements, we have released an online GenePattern Notebook repository and workspace where researchers can collaboratively develop and publish notebook documents. It provides a complete Jupyter environment, connections to several GenePattern servers, and for programmers, the common Python packages used in bioinformatics analysis (numpy, pandas, matplotlib, scikit, etc.). We seeded the repository with notebooks that provide commonly used machine-learning methods: clustering, classification, and prediction, as well as dimension reduction and differential expression analysis.
Those who wish to run the GenePattern Notebook environment on their own compute resources have two options. (1) Non-programmers can install the Kitematic Docker (kitematic.com) application and use it to run the GenePattern Notebook Docker image, available on the standard Docker Hub repository (hub.docker.com). This provides a complete, ready-to-run notebook environment with all dependencies preinstalled. (2) Programmers may install the GenePattern Notebook and its dependencies through the pip or conda package manager interfaces.
To our knowledge GenePattern Notebook is the first integration of a bioinformatics tool aggregation portal with an analysis notebook environment. This approach benefits both nonprogramming and programming investigators alike. For the nonprogrammer, GenePattern Notebook provides the user-friendly GenePattern genomic analysis capabilities within a publishable notebook format. For the programmer already using the Jupyter environment, it affords easy access to the entire GenePattern library of analysis and visualization modules that can be supplemented with the investigator's own coded routines.
The GenePattern Notebook environment, along with an introductory demonstration video, documentation, and tutorials, is available at www.genepattern-notebook.org. The software is freely available under a BSD-style open source license.

Pattern Recognition in Meteograms, Oct 19 17:00-18:15 MDT (1)
Pattern Recognition in Meteograms
Meteograms, the display of multiple forecast weather parameters in time series, have recently become a very popular and useful decision making tool for avalanche operations worldwide. Traditionally, meteograms are evaluated based on the absolute numbers alone. In this presentation, we will look at the general behaviour and patterns of these parameters and how they interact with each other. We will unlock this additional information to increase the understanding of the underlying data and improve the weather related decision-making process in general.


The magnetic separator unit was developed and built on customer request to investigate the separation behavior of magnetically removable impurities from aqueous solutions using a magnetic separator.
The center piece of the unit is the flow tank, in which 13 neodymium permanent magnets are embedded in special receiver tubes. Using hydraulic cylinders, the magnets can be retracted or extended of the flow tank, automated or manually. The particles accumulate during the experiment on the receiver tubes and are automatically rinsed with water from the receiver tubes after extension of the magnets. In addition to the volume flow and the length of the experiment respectively contact, the flow behavior within the flow tank can be varied using specially manufactured perforated plates. In addition to the pure separator function, the unit has an automated draining of the flow tank, a rinsing of the magnet receiver tubes and a sludge discharge from the flow tank.
All functions and process steps are controlled and monitored via a PLC. The process parameters are variable and can be adapted individually at any time. All measurement and control data can optionally be extracted from the PLC and recorded, standardized and visualized via an external data acquisition system. The test data are stored in a format readable by excel.
Field of use:
- Experiments to separate magnetically removable particles from different aqueous solutions
- Investigation on the separation behavior of magnetically removable particles from aqueous solutions by changing the flow behavior
- Optimization of process parameters
- Cleaning and rinsing investigations oft he magnet receiver tubes and the flow tank
Further technical information is given in the Data Sheet.

Didn’t use PC much at home recently and because of that hadn’t been using linux for a couple of month. Logged in today and all of a sudden got an issue – seeing weird CPU usage spikes and hitches even when simply moving the mouse. Hadn’t experienced that before =( Tried to update video drivers (typically, the main source of problems in the linux world), updated all packages in the system – still no luck. Forums, mostly, suggest checking CPU and GPU cooling and I would’ve agreed but windows seems working okay. Not that this is a show-stopper now, as I said, I barely turn my PC on now, but I’m still going to dedicate some time for programming later, and, in general, I feel more comfortable using linux. Hope I’ll figure out what’s going on and won’t have to re-install the system.
Update: fixed everything up. Turned out that that my TV was the culprit – the system was constantly updating connection to it (still have no idea why) and it was eating up CPU. The xorg.0.log was flooded with messages:
[ 99.218] (–) NVIDIA(GPU-0): Sharp LC-40LB480U (DFP-3): connected
[ 99.218] (–) NVIDIA(GPU-0): Sharp LC-40LB480U (DFP-3): Internal TMDS
[ 99.218] (–) NVIDIA(GPU-0): Sharp LC-40LB480U (DFP-3): 340.0 MHz maximum pixel clock
Switched the GPU outputs for the display and the TV – and everything returned back to normal.

Ubuntu testdrive is AWESOME. In my words, testdrive lets you test the next version of ubuntu in a VM with a single command.
testdrive ultimately just creates a disk image and runs a virtual machine for you, lets you step through the install from the nightly CD, and then lets you continue to run that VM. I decided to use the exactly same disk image and vm command line to testdrive fedora.
- Download fedora cd image :
curl -O http://download.fedoraproject.org/pub/fedora/linux/releases/16/Live/x86_64/Fedora-16-x86_64-Live-Desktop.iso
- copy a disk image : cp .cache/testdrive/img/testdrive-??????.img fedora16.img
- start the install : kvm -m 2048 -smp 2 -cdrom Fedora-16-x86_64-Live-Desktop.iso -drive file=fedora.img,if=virtio,cache=writeback,index=0,boot=on -usb -usbdevice tablet -net nic,model=virtio,macaddr=DE:AD:BE:EF:A8:CC -net user -soundhw es1370 -vga std -vnc 127.0.0.1:0 -k en-us
- That copy a disk image step could probably be done much better by creating the qcow2 file yourself, but this worked for my immediate need.
- The differences in the command line from a testdrive command line, on my system, are memory size (1024/2048) and -vga cirrus v. -vga std.

Pilot Experience: play and program with Bee-Bot to foster computational thinking learning in young children. In 7th International Engineering, Sciences and Technology Conference (IESTEC). presented at the 12/2019, Panama, Panama: IEEE. doi:10.1109/IESTEC46403.2019.00113. (2019).


UPDATE: Steve Hemmerstoffer has distributed a 360-degree render video and Max Weinbach has shared some early insights regarding the Galaxy S21 Ultra camera arrangement. The refreshed story proceeds beneath..
Under 12 hours in the wake of displaying the standard Samsung Galaxy S21 in full unexpectedly, Steve Hemmerstoffer is back with CAD-based renders and a 360-degree video of the exceptional Galaxy S21 Ultra 5G.
Samsung Galaxy S21 Ultra specifications and display
Like the Samsung Galaxy S21, the Ultra-marked model is reputed to dispatch with the unannounced Qualcomm Snapdragon 875 in the United States. Purchasers in Europe, then again, should manage with the Exynos 1000 or 2100 (name to be affirmed).
These chipsets ought to sit close by at least 128GB of capacity and 12GB of RAM in all business sectors. MicroSD card uphold is likely as well, albeit different models with additional capacity and RAM are accepted to be a work in progress.
On the product side of things, expect Android 11 and One UI 3.0 pre-introduced. The spilled renders affirm clients will have the option to collaborate with the product on a huge 6.9-inch AMOLED show with unpretentious bends on either side.
Samsung has chosen insignificant bezels and a considerably more slender jaw, notwithstanding a focused punch opening for the selfie camera, the last of which has become the brand’s particular investigate the previous a year.
Anyone stressed over the battery will be satisfied to hear the Galaxy S21 Ultra is supposed to include a 5,000mAh battery life its archetype. Because of better effectiveness in the chipset and 5G modem office, longer battery life is nearly ensured.
With regards to by and large measure, the Galaxy S21 Ultra is somewhat more modest than the Galaxy S20 Ultra (166.9 x 76 x 8.8 mm) at 165.1 x 75.6 x 8.9mm. For additional reference, the Galaxy Note 20 Ultra measures in at 164.8 x 77.2 x 8.1 mm.
Samsung will continue the massive camera bump trend
At the point when we turn the Galaxy S21 Ultra over, it’s unmistakable the cell phone continues in the strides of its more modest kin. It receives the new camera knock plan that Samsung is concocting, which implies one that folds around the edges and features singular sensors.
Be that as it may, the sheer size of the knock appears to propose Samsung needs to take the arrangement to another level. The spilled renders uncover plans for a LED glimmer and four cameras, up from three on the Galaxy S21.
Max Weinbach recommended that another rendition of the 108-megapixel sensor presented on the Galaxy S20 Ultra is normal close by a 16-megapixel camera. The last may uphold super wide-point abilities.
The last two cameras will offer 10-megapixel goals. Late bits of gossip propose they could be periscope and fax zoom shooters that empower a substantially more progressed zoom framework.
When will the Samsung Galaxy S21 Ultra 5G be released?
Samsung presented the Galaxy S20 arrangement in February and delivered the cell phones in March. Yet, with Huawei now incapable to contend outside of China and different contenders delivering their gadgets months after the fact, Samsung is exchanging up its dispatch timetable.
Steve Hemmerstoffer, Max Weinbach, and Android Central have validated late reports about a Galaxy S21, Galaxy S21+, and Galaxy S21 Ultra uncovering in January followed by a delivery in February. That is an entire month sooner than expected and implies there will be not many contending leads available.
Lamentably, there’s no word on estimating plans right now. Yet, considering the analysis Samsung looked because of its high Galaxy S20 costs, the Galaxy S21 Ultra ought to be somewhat less expensive than its archetype.

How spatial computing and the industrial metaverse can unlock new value for the design, construction and operations of infrastructure projects
Greg Demchak, Senior Director, Digital Innovation Lab, Bentley Systems
Spatial computing and the industrial metaverse are emerging technologies that enable immersive and interactive experiences. These technologies can offer significant value for the design, construction, and operations of infrastructure projects, such as bridges, roads, railways, and buildings.
The obvious benefit is the enhanced collaboration and communication among stakeholders, such as engineers, architects, contractors, and clients, across different locations and devices. Improved collaboration can lead to improved design and planning, allowing users to visualize, simulate, and test different scenarios and alternatives in a realistic and scalable environment.
Furthermore, digital rehearsals increase efficiency and safety, by reducing errors, rework, and waste, and by providing feedback, guidance, and training for workers and operators based on direct experience of the digital twin.
Finally, these 3D experiences can optimize performance and maintenance, by enabling remote monitoring, inspection, and diagnosis of assets, and by leveraging data analytics and artificial intelligence, we can introduce co-pilots to augment the users.

The collaboration will combine Samsung’s Galaxy 5G mobile devices and advanced end-to-end enterprise network solutions with IBM’s network management, hybrid cloud, and edge computing offerings. It’ll also include IBM’s industry solutions that integrate artificial intelligence (AI) and Red Hat’s open architecture.
IBM and Samsung said the goal is to develop “open, hybrid cloud solutions that enable enterprises to draw greater insights from data at the edge – from the factory floor to an oil rig or a regular office space – to improve operational performance, increase worker safety, and minimize downtime.”
The companies are also looking to help enterprises use 5G in public and private networks through cross collaborations with global mobile operators. Earlier this year, Samsung announced a project with IBM, the Singapore Infocomm Media Development Authority, and telecom provider M1 to showcase Smart Factory advancements, including 5G-enabled AI analytics and AR capabilities.
Additionally, Samsung and IBM’s collaboration in private 5G networks will enable enterprises to adopt emerging technologies crucial to Industry 4.0, such as the internet of things (IoT), AI, cloud, edge computing, and augmented reality (AR). It’ll also introduce innovations across businesses that can enable employees to identify faults in manufacturing lines using AI-powered image recognition, employ thousands of sensors to build smart agriculture solutions, or facilitate employee training and productivity using AR.
As part of this collaboration, Samsung, IBM, and Red Hat plan to deliver AI-powered solutions for industry using 5G devices, cloud-native 5G networks, and edge computing platforms. Specifically, the companies intend to explore Samsung hardware and software’s interoperability and integration with IBM Edge Application Manager, which runs on Red Hat OpenShift and AI to enable computing workloads to be managed and deployed to Samsung’s portfolio of mobile devices at an industrial scale.
Steve Canepa, global GM and managing director, communications sector at IBM said the communication networks’ transition from proprietary architecture to intelligent, software-defined hybrid cloud platforms enables the creation of enormous new value in the 5G and edge era.
“5G devices and network solutions from Samsung, along with IBM and Red Hat’s open, hybrid cloud capabilities, can help organizations across all industries accelerate their transformation and solve real business problems while unlocking the true power of 5G and edge,” Canepa added.

The paper presents new knowledge concerning effects of faults on hv overhead lines on near buried telecommunication cables. First, several analytical and numerical methods have been used to find the potential distribution near the cable and on its surface, which represents the first step for determining the stress distribution within its insulation. Second, some simple measures are suggested to decrease the harmful influences and their effectivity is evaluated.
The oxidation of Fe AREMA wires is investigated in this paper. Iron samples were oxidized at 1100°C in ambient air. The periods of oxidation time varied from 10 hr up to 80 hr. Weight and size measurements, metallography, and chemical microanalysis were used as experimental methods. In has been found that the Fe wires being of 3 mm in diameter are partly oxidized at the oxidation times 10 up to 20 hr, and completely oxidized at >= 40 hr. Metallographic investigations have shown that the partly oxidized samples contain Fe remainders of cylindrical shape. Microchemical analysis has revealed that the scale mass produced in the course of oxidation process, 1020 hr, contains approximately 54 at. %O, and cca 58 at. %O in completely oxidized samples, 4060 hr.
Thermally activated processes in a disordered polymer structure are approached as a superposition of reversible chemical reactions with distributed activation energies. A modified activation volume concept is used and the relevant distribution function is derived inclusive of its temperature and pressure dependence. A symmetrical exponential distribution of activation energies is identified as the only possible cause that i) brings about the power-law dependence of the polarisation and depolarisation current after a step-wise change of the electric stress and ii) shapes the frequency characteristics of the dielectric in the form of more or less flat arcs of the complex permitivity. The existence of the skewed arcs of the frequency dependences is attributed to the presence of an unoccupied free volume that is distributed exponentially in the polymer at temperatures higher than the temperature of glass transition. It is the free volume that causes a not symmetrical distribution of activation energies. The paper presents examples of the DC and AC characteristics, which have been calculated according to the discussed models. The skewed arcs of the frequency characteristics are compared with the classical data of Negami and Havriliak.
This paper reports the results of finite element calculations carried out on a double shear creep specimen geometry suggested in . The stress and strain distribution during the creep exposition under conditions corresponding to the applied experimental set up is presented and discussed. It is concluded that the suggested geometry of the specimen and corresponding experimental set up are suitable for double shear testing.
An analytical theory of quenching macroscopic residual stresses in thermally sprayed thick coatings and free-standing plates (FSP) is presented. The theory is based on a simplified model of continuous spraying. Layers of infinitesimal thickness are gradually deposited and immediately cooled down to the constant bulk deposit temperature. The general formulation is given for inhomogeneous coatings and FSP with the material properties depending on the coordinate perpendicular to the plate plane. The cases of homogeneous coatings and FSF are discussed in detail. The secondary stresses formed during final cooling to the ambient temperature are commented.
A basic body suspended on two rods and capable of swinging as a pendulum in a horizontal direction is excited kinematically through a harmonic motion of its suspension points. An additional mass is elastically attached to the body, to function in either vertical (System I) or horizontal direction (System II) similarly as a dynamic absorber. The conditions for an optimal tuning and damping are investigated.
Self-organized current filaments between two concentric contacts in an n-GaAs epitaxial film have been investigated in a magnetic field perpendicular to the sample. Two-dimensional spatial images of the current density distribution have been obtained by the method of quenched luminescence. It is shown that under the influence of an increasing transversal Lorentz force the static filaments are at first bent, then destabilized and finally the filament image gets completely blurred. Time resolved recordings of the sample voltage in the last stage reveal very complex but strictly periodic oscillations. Their analysis as well as other experimental results indicate that these oscillations are caused by filaments rotating around the central contact.
Various methods of diagnostics of nonlinear transitions were tested on experimental data acquired in a mercury vapour arc discharge exposed to the external magnetic field. The time series reflecting the arc current and optical radiation from two different parts of the arc column were analyzed using various methods of signal processing including the FFT, correlations, correlation dimensions and wavelets. The capabilities of the applied methods are illustrated on an example of the system evolution with transitions between oscillation regimes characterized by different types of subharmonic frequencies.
