A computer network can be defined pretty simply as “a collection of inter-connected & communicating computational devices that can share resources”.
The devices that form a network can be connected both by wire and wirelessly. They tend to communicate via Radio Waves or Infrared when communicating wirelessly.
Important Characteristics of A Computer Network
- The devices forming the network must be interconnected
- The network must be able to function autonomously
Firstly, to have a network, the devices need to be connected to each other. Without a connection, a device a will not be apart of the network. Without any connections at all, there are no devices!
What Are The Objectives of A Computer Network?
- Data sharing and exchange
- Sharing resource expensive processes and files
If you want to send a file to a friend, you and your friend need to be connected in some manner.
Additionally, there are vast networks such as the software underlying Bitcoin technology. These networks function only because everyone uses it and shares resources with this network.
Another two examples of data and resource sharing are Torrents and Peer-2-Peer file-sharing.
You now know what a computer network is and also what it’s used for. New articles are coming every morning! Leave a comment, let me know what you think!
Until next time, Josh.


LeEco, a Chinese mobile phone enterprise you’ve likely never heard of, announced a few new phones this early morning – and all a few have USB Kind-C connectors in position of a regular headphone jack.
The Le2 qualified prospects the pack it truly is a 5.5in, 1080p mobile phone that’s borrowed more than a bit of style inspiration from the Iphone, HTC 10 and Huawei P9.
Within, you get a Helio X20 CPU, 3GB of RAM and 32GB of storage, along with a 3000mAh battery. There’s a 16MP digital camera on the back again and an 8MP snapper on the front.
The Le two has two larger brothers, the Le Max2 and Le 2Pro – we’re beginning to question if the guy coming up with the names has a broken area bar on his keyboard.
A Helio X25 CPU and 4GB of RAM give the Le 2Pro an edge more than the basic mobile phone when it will come to speed, and techniques up its digital camera activity with a 21MP Sony sensor on the back again.
Issues get properly ridiculous with the Le Max2, which LeEco states is “optimised for VR”. That means a 5.7in QHD display screen, fast Snapdragon 820 CPU, and both 4GB/32GB or 6GB/64GB of RAM and onboard storage.
The battery gets a modest bump to 3100mAh and Qualcomm’s SenseID ultrasonic fingerprint sensor turns up on the back again underneath the digital camera. The pixel depend stays the identical as the Le 2Pro, but it also gets optical image stabilisation.
With USB Kind-C ports on the base of all a few phones, flanked by two speaker grilles, you’ll need to have a pair of LeEco’s USB Kind-C headphones to pair with them. You’ve got obtained a choice on in-ear and on-ear, but LeEco states equally are great for lossless audio.
We were not anticipating any of these phones to make their way out of China any time soon, but LeEco reckons at the very least 1 will start in the US sometime this 12 months.
Pre-orders open up in China currently, with the Le two costing 1099RMB / US$170 and the Le 2Pro setting you back again 1499RMB / US$232. The 4GB/32GB Le Max2 is heading for 2099 RMB / US$325, and the 6GB/64GB design will price tag 2499 RMB / US$387.
LeEco’s not only about smartphones, though. It really is also acquiring into electric vehicles in a significant way.
It pumped investment decision into Farraday Long term and Aston Martin before this 12 months, and now it truly is obtained an electric automobile of its have: the LeSEE.
Extra of a notion automobile than something you’ll basically be ready to travel any time soon, the LeSEE is a indicator of matters to occur from electric automobile organizations that are not Tesla.
Appropriate now, the notion can quickly travel and park itself with voice prompts from a smartphone application.
Suicide doors for the rear passengers and enormous touchscreens in the driver’s cabin? Yep, that’s really notion to us. It need to make a complete debut upcoming week at the Beijing Motor Exhibit.

First, the principle of brush motor
To clarify this issue, you should have a rough understanding of how the brush motor works. Next, a three-electrode, two-pole inner rotor brushed motor was used as a demonstration.
Second, the working principle of brushless motor
First of all, the brushless motor is not a DC motor. Although the model is powered by a DC battery, it is converted to three polarities by three-phase alternating current after brushless ESC. As can be seen from the figure below, the brushless motor has no carbon brush. In contrast to the brush, the magnet of the brushless motor becomes the rotor~
Third, the name of the brushless motor
Compared with the brush motor, the name of the brushless motor is well understood. Generally, it consists of four numbers, such as a 2040 brushless motor. This figure only represents the external dimensions of the motor. 2040 represents a motor with a diameter of 20 mm and a length of 40 mm. Similarly, the 3650 brushless motor indicates that the motor has a diameter of 36 mm and a length of 50 mm.
In fact, the size of the 370 brush motor is the same as that of the 2530 brushless motor. The size of the 540 motor is the same as that of the 3650 brushless motor.
Fourth, the characteristics of brushless motor
1. There is no carbon brush. In theory, the rotor does not need to have a link with the outside world.
2. During the running process, the speed of the brushless motor is determined by the frequency of the alternating current, so the higher the frequency, the faster the brushless motor can turn.
3. The speed of the brushless motor is set strictly according to the KV value. 1000KV means that the speed of each Ford motor is 1000 rpm. Therefore, when the voltage is 5V, the 1000kv brushless motor rotates at 5000rpm.
So why do we want to sense this stuff? To clarify this problem, we must start with a shortcoming of feeling no brush. Just said that the speed of the brushless motor is determined by the frequency of the alternating current, then the ESC should try to figure out the current motor speed and the current state of the motor. In fact, this is very easy for a motor that is already running normally, but it is more troublesome for a motor that has just started or is running very slowly (it is difficult to accurately measure the state of the motor speed), so there is no feeling. The brush motor will not be linear or even tremble at low speeds, and the starting torque will not be stronger than the same level brush motor.
However, it has been found that the Hall effect of any brushless motor is obvious, so it is easy to know the operating state of the high-speed or low-speed motor through the Hall effect ESC, thus solving the problemless brushless motor. The fault of the motor! But for the time being, Hall sensors are not cheap goods, so the price of brushless motors and ESCs is much more expensive than non-sense.
Seven, common models with brush, no sense of no brush, sense of brushless motor comparison

Who would had know after all these years that this probe would still be sending information about our solar system back to us and still kicking ass. It is now the furthest man-made object from earth, about 10 billion miles away. In the next 4 years it will be exiting our solar system completely. 1977 was when it was launched. Unbelievable.
Via Telegraph UK: The NASA space probe was launched in 1977 and passed by Jupiter, Saturn, Uranus and Neptune before veering north.
It is now 10.8 billion miles from the sun travelling at a speed of 38,000 mph.
The solar wind, a stream of charged particles spewing from the sun, has slowed to a speed of zero and is moving sideways rather than outwards, marking the end of the solar system.
Nasa said the 722kg probe would take another four years to fully exit the solar system and enter interstellar space, the area between the influence of the sun and the next star system. The space agency described it as a “major milestone” in space exploration.

There are so many questions asked by non-geeks and those of old age who do not understand how the hell the technology works.
I don’t blame them. There are really dozens new gadgets being released on daily basis. Computers and other tech gadgets are getting older day by day and replaced by their superior competitors.
One of the newest technological invention is bluetooth receivers. I know that bluetooth is quite old now, I remember first colored phones supported bluetooth and that was something very new!
Bluetooth is everywhere now. Each and every device must have bluetooth support otherwise, they will not be integrated into our daily lives.
So, what the hell is bluetooth receiver? It is a great device that works pretty much like wireless interent. Except that it requires no internet connection. Now imagine hands free system in your car via bluetooth. You connect your phone to the radio in the car and whenever someone called, the audio is transfered from your phone to the radio so you hear and all without actually using your phones. This is great. Now imagine the same principle applied everywhere where data can be received.
Fir example, your speakers – speakers will receive data via best bluetooth receiver you have and output the sounds. That is how speakers work – they receive the information, convert it into the sounds and play the music. That information will be transfered via bluetooth receiver.
Why would you do such thing, you may ask? Well, there are cables that are very annoying. With this device you will no longer need any cables, you just plug this device in, and here you have it – all the information and data will be transfered from your music device to the speakers that will convert the data into the music. This is best thing ever.

Before you can start using any function from Vulkan and vulkano, the first thing to do is to create an instance. Creating an instance tries to load Vulkan from the system and reads the list of available implementations.
Creating an instance takes three optional parameters which we aren't going to cover for now. You can
check the documentation of
for more information.
use vulkano::instance::Instance; use vulkano::instance::InstanceExtensions; let instance = Instance::new(None, &InstanceExtensions::none(), None) .expect("failed to create instance");
Like many other functions in vulkano, creating an instance returns a
Result. If Vulkan is not
available on the system, this result will contain an error. For the sake of this example we call
expect on the
Result, which prints a message to stderr and terminates the application if it
contains an error. In a real game or application you should handle that situation in a nicer way,
for example by opening a dialog box with an explanation. This is out of scope of this guide.
Before going further you can try your code by running:
The machine you run your program on may have multiple devices that support Vulkan. Before we can ask a video card to perform some operations, we have to enumerate all the physical devices that support Vulkan and choose which one we are going to use for this operation.
In reality a physical device can be a dedicated graphics card, but also an integrated graphics processor or a software implementation. It can be basically anything that allows running Vulkan operations.
As of the writing of this guide, it is not yet possible to use multiple devices simultaneously in an efficient way (eg. SLI/Crossfire). You can use multiple devices simultaneously in the same program, but there is not much point in doing so because you cannot share anything between them. Consequently the best thing to do in practice is to choose one physical device which is going to run everything:
use vulkano::instance::PhysicalDevice; let physical = PhysicalDevice::enumerate(&instance).next().expect("no device available");
enumerate function returns an iterator to the list of available physical devices.
next on it to return the first device, if any. Note that the first device is not
necessarily the best device. In a real program you probably want to leave the choice to the user.
Keep in mind that the list of physical devices can be empty. This happens if Vulkan is installed on the system, but none of the physical devices of the machine are capable of supporting Vulkan. In a real-world application you are encouraged to handle this situation properly as well.

Power cable has been invented for more than a hundred years, and it has been more and more widely used as the times progress. The copper conductor power cable nowadays is mainly used for underground burying, because it can resist high-strength compression on the ground and has a high degree of corrosion resistance. In the construction sites of many major projects, insulated power cable is an indispensable role.
Here is the content list:
- What role does power cable play in the domestic market?
- How is the structure of the power cable designed?
- What are the advantages of power cable?
What role does power cable play in the domestic market?
Power cable is a large class of electrical products used in the fields of power transmission and distribution, power transmission, sound, text, image, and other information dissemination and lighting.
What's more, protected power cable is an indispensable basic equipment for the manufacture of various motors, electrical appliances, and meters. It is also a necessary basic product for power infrastructure construction, new smart grids, and new energy industries.
The power cable industry occupies a large part of the output value of the domestic electrical industry, and is the second largest industry in our country after the automobile industry. Now, the output value of domestic power cable has surpassed other countries, becoming the world's first.
The huge production capacity formed by our power cable enterprise has impressed the world. With the continuous expansion of the domestic power industry, data communication industry, urban rail transit industry, automobile industry and other industries, the demand for power cable will also grow rapidly, and the power cable market has huge development potential in the future.
How is the structure of the power cable designed?
Power cable is a cable used to transmit and distribute electrical energy. It is often used in urban underground power grids, power station outlet lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across the river.
A power cable is a wire core made by twisting one or several wires, wrapped with a corresponding insulating layer, and covered with a sealed metal or plastic protective layer. This structure can protect the core from external damage.
The core is the conductive part of the power cable, used to convey power, and is the “core” section.
- Insulation layer
The insulating layer can electrically isolate the wire core from the outside world or other ones to ensure electric energy transmission. It is an indispensable part of the power cable structure.
- Shield layer
Power cables of 15 KV and above generally have conductor shielding layer and insulating shielding layer.
- Protective layer
The function of the protective layer is to protect the power cable from the intrusion of external impurities and moisture, and to prevent the power cable from being directly damaged by external force.
What are the advantages of power cable?
There are basically two modern transmission and distribution lines, overhead power lines and power cable lines. In places with dense urban residents or special occasions, for safety reasons, power cables are basically used, which has high practicability and safety performance.
Power cable occupies less land, because it is generally buried in the soil or indoors, in trenches, tunnels, and the insulation distance between the lines is small, so there is no need for towers. The power cable laid underground does not occupy ground space, and the same underground passage can accommodate multiple circuits.
Power cable has high reliability, natural weather conditions (such as lightning, wind and rain, salt spray, pollution, etc.) and the surrounding environment have little influence on the cable, which ensures stable transmission performance and high reliability.
Power cables have favorable conditions for the development of ultra-high voltage and large capacity, such as low temperature and superconducting power cables. Its maintenance workload is less, so the operation and maintenance costs are relatively small.
Although insulated power cable has many advantages, it has disadvantages such as high cost and difficulty in troubleshooting and complicated cable joint technology.
Therefore, the person in charge of the project should weigh the pros and cons in the selection. You can give the choice of copper conductor power cable to People's Cable Group Co., Ltd., as a professional aluminum power cable manufacturer, we will provide comprehensive services and support to help you play its true value, reduce costs for the project, and in the long-term increase income.


Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is used to transmit binary data over channels that only support ASCII text, such as email messages or HTTP requests.
In Base64, each three bytes of binary data are represented by four characters from a set of 64 characters, which consist of uppercase and lowercase letters, digits, and two additional characters, typically “+” and “/”.
The encoding process converts the binary data into its corresponding ASCII representation, while the decoding process converts the ASCII representation back into the original binary data. Base64 is widely used in web development and other computer applications for encoding and decoding data.


After building the first government mobile ground magnetometer and traversing tens of thousands of miles taking magnetic data, I had a natural thesis topic–interpreting some of the data.
I chose a small section of traverse in northeastern Minnesota, where lava flows lie in horizontal layering.
To make it unique, I used the variable magnetic properties in the flows to determine the depth of a highly magnetic layer overlain by a less magnetic layer. To do this I analyzed the rock magnetism that the seemingly erratic magnetic field traverse exhibited.
To analyze the traverse data I used Fourier (wavelength) analysis. To convert the traverse data from a line on chart paper to wavelength form I developed an electro-optical converter using an oscilloscope and camera.
(I know this is getting boring. If you want to know more, read my Master’s Thesis. I have two copies.)
Using this unique and clumsy system I was able to show that a less magnetic layer (rhyolite) is about 70 feet thick at the traverse location, and overlies a more magnetic (gabbro) layer. The test also gave some indication of the magnetic inhomogeneity of both layers.
At Prof. Mooney’s request I sent a short description of the technique and my results to Isidore Zietz, a geophysicist and magnetic expert with the US Geological Survey in Washington, DC. Dr. Zietz replied that it appeared to be a Ph.D. level thesis. He passed my letter on to James Balsley, head of USGS geophysics branch. The letter to me from Dr. Zietz contained a handwritten note from Dr. Balsley in support, with recommendations for further work.
Being more interested in field exploration at the time, I did not follow up on Dr. Balsley’s suggestions.


ESA supports new satellite research project in Greenland on surface water
Greenland is one of 5 countries selected to participate as an example in a new 2-year research project on mapping surface water resources funded by ESA (European Space Agency).
The project has been named WorldWater. The overarching goal of WorldWater is to empower national and regional authorities and institutions with earth observation data and tools to better monitor their water resources and report on the global SDG 2030 Agenda - particularly reporting on Global Goal 6.

Saarland Informatics Campus
Building E1.1, Room 2.28
Hi there 👋 My name is Adrián, and I am a PhD student at the Probabilistic Machine Learning group under the supervision of Isabel Valera at Saarland University. I am also an alumnus of the Empirical Inference department at the Max Planck Institute for Intelligent Systems. Before pursuing my PhD, I completed a Master in Computer Science and a double Bachelor Degree in Computer Science Engineering and Mathematics at the University of Murcia.
I am mostly interested in principled research that aims to improve machine learning methods, making them easier to use and more robust. Specifically, my current research focuses on improving models that optimize different tasks simultaneously. This includes apparently unrelated areas such as multitask learning (MTL) and deep probabilistic generative models (e.g. VAEs) under heterogeneous environments.
However, I am a curiosity-driven, and I am always happy to discuss interesting ideas even if they lie outside my comfort zone. Feel free to reach me out via Twitter or email.

MTN Ghana officially launched an electronic SIM service in Ghana a few days ago with the aim of improving their offering of quality and digital services to all their customers. An Electronic sim is a computer-generated SIM that is built-in in mobile and smartphones during manufacturing time. MTN Ghana has one primary goal, “to lead the delivery of a bold, new digital world to all their customers,” They also aim to achieve their vision by 2025. Most West African nations have already launched Electronic SIM.
The electronic service includes prepaid, postpaid, and commercial services already available to all MTN customers. Customers can only access these services through the MyMTN application. MTN revealed that they would upgrade all the customers with already registered numbers and sim cards to Electronic SIM. The Electronic Service allows Customers to simultaneously use various mobile numbers while using one device without necessarily switching out SIM cards.
MTN Ghana noted that anyone who activates Electronic SIM for the first time would be awarded 10 GB data bundles with no expiry date. Ghanaians can now access Electronic SIM in their country. All users with Electronic Sim Compatible devices will not need physical SIM cards; therefore, they will be able to use varied providers on the same device.
AirtelTigo was the first network operator to offer Electronic SIM in Ghana. AirtelTigo is a Ghanaian-owned telecommunication company that offers a wide range of dynamic and advanced telecommunications services, as well as mobile voice, data, mobile financial services, and business connectivity services. The Chief Executive Officer AirtelTigo, Leo Skarlatos, has insisted that Electronic SIM is among the digital revolution Ghana is working to achieve. “With the introduction of eSIM, AirtelTigo continues to stay ahead of the curve where innovation is concerned by giving its customers the much-desired flexibility to use the most advanced devices available globally and stay abreast with current technological trends. We constantly strive to deliver on our promise, Making Life Simple for all our customers through innovative products and services,” noted Leo Skarlatos.
The Chief Marketing Officer AirtelTigo, AtulNarain Singh, said, “eSIM provides added flexibility to eSIM compatible devices by transforming them from single SIM to dual SIM devices. AirtelTigoeSIM will also make Life Simple for customers who are frequent international travellers and must manually switch between SIMs whenever they cross borders. Smartphone users can dial *#06# to check whether their devices support eSIM or not; phones supporting eSIM will show a barcode with ‘EID’ at the beginning of the code on the screen. We are very confident that our existing and new customers will move quickly to our eSIM for what it delivers.”
The Minister for Communication and Digitalisation, Ursula Owusu-Ekuful, has congratulated AirtelTigo for their devotion to introducing the most suitable communication technology. The new service is meant to help improve the country’s telecommunication service and eliminate physical SIM cards.
You must activate the Electronic SIM on whichever network you are using. Activation can only be done using the MyMTN application. Using the application, you choose the Menu symbol and then choose the Electronic SIM option. Once you choose the electronic SIM network, key in your MTN number, and you will receive an OTP. After entering the OTP, you will see a form in which you must provide all your personal information, such as name and email address. Besides, you will be required to upload a profile picture and a National Identity card. Once you submit, you will receive more information concerning the activation of the Electronic SIM. All customers with electronic SIM-enabled phones are requested to visit their telecommunication network to secure an electronic Sim.


Decoding the Codes: Difference between AI and Generative AI-TECHVIFY
One of the fastest to integrate OpenAI seamlessly into their industry was Publer—leveraging the power of generative AI to automate social media content creation. It’s headed by its President and Chairman, Greg Brockman, Chief Scientist, Ilya Sutskever, and Sam Altman, its CEO. Most people don’t know Elon Musk started OpenAI back in 2015 but later stepped down from his position in February 2018 due to potential conflicts with Tesla. OpenAI has one goal—ensuring fully autonomous systems that outperform humans benefit all of humanity. Examples of generative AI include ChatGPT, DALL-E, Google Bard, Midjourney, Adobe Firefly, and Stable Diffusion. As a result, LLM software has been known to generate inappropriate content.
Our marketing automation software — MarketingCloudFX — allows you to optimize your marketing strategies and campaigns using artificial intelligence. This approach raises brand recognition, leads generation, and ultimately revenue growth. Output from these systems is so uncanny that it has many people asking philosophical questions about the nature of consciousness—and worrying about the economic impact of generative AI on human jobs.
Hiring kit: Principal Software Engineer
Organizations can create foundation models as a base for the AI systems to perform multiple tasks. Foundation models are AI neural networks or machine learning models that have been trained on large quantities of data. They can perform many tasks, such as text translation, content creation and image analysis because of their generality and adaptability.
As businesses and organizations increasingly embrace the power of AI-driven conversations, they are poised to tap into this lucrative market opportunity and unlock the immense potential it holds. It’s important to note that generative AI presents numerous issues requiring attention. One major concern is its potential for spreading misinformation or malicious or sensitive content, which could cause profound damage to people and businesses – and potentially pose a threat to national security. General AI, also known as artificial general intelligence, broadly refers to the concept of AI systems that possess human-like intelligence.
Main differences between conversational AI and generative AI functionality
The key characteristic of generative AI is its ability to create something that does not exist in the training data explicitly. It captures the underlying complexity and diversity of the input and produces unique outputs that exhibit creativity and originality. This makes generative AI a powerful tool for artists, designers, and content creators seeking to explore new frontiers and push the boundaries of human creativity. The benefits of generative AI include faster product development, enhanced customer experience and improved employee productivity, but the specifics depend on the use case. End users should be realistic about the value they are looking to achieve, especially when using a service as is, which has major limitations.
In the short term, work will focus on improving the user experience and workflows using generative AI tools. A generative AI model starts by efficiently encoding a representation of what you want to generate. For example, a generative AI model for text might begin by finding a way to represent the words as vectors that characterize the similarity between words often used in the same sentence or that mean similar things. Joseph Weizenbaum created the first generative AI in the 1960s as part of the Eliza chatbot.
Founder of the DevEducation project
A prolific businessman and investor, and the founder of several large companies in Israel, the USA and the UAE, Yakov’s corporation comprises over 2,000 employees all over the world. He graduated from the University of Oxford in the UK and Technion in Israel, before moving on to study complex systems science at NECSI in the USA. Yakov has a Masters in Software Development.
It might produce a function that takes an argument as input that is never used, for example, or which lacks a return function. This has raised many profound questions about data rights, privacy, and how (or whether) people should be paid when their work is used to train a model that might eventually Yakov Livshits automate them out of a job. And a third group believes they’re the first sparks of artificial general intelligence and could be as transformative for life on Earth as the emergence of homo sapiens. Proponents believe current and future AI tools will revolutionize productivity in almost every domain.
- In addition to natural language text, large language models can be trained on programming language text, allowing them to generate source code for new computer programs. Examples include OpenAI Codex.
- The vector serves as a representation of the input sample data, which is understandable by the model.
- One of the primary advantages of generative AI is its ability to create new content that is similar to human-generated content, which can be useful in applications such as art or music.
- It is crucial to emphasize that Artificial Intelligence and Artificial General Intelligence are not interchangeable terms.
The field accelerated when researchers found a way to get neural networks to run in parallel across the graphics processing units (GPUs) that were being used in the computer gaming industry to render video games. New machine learning techniques developed in the past decade, including the aforementioned generative adversarial networks and transformers, have set the stage for the recent remarkable advances in AI-generated content. Whether it’s creating art, composing music, writing content, or designing products.
Are AI tools advanced enough for product documentation?
Microsoft’s decision to implement GPT into Bing drove Google to rush to market a public-facing chatbot, Google Bard, built on a lightweight version of its LaMDA family of large language models. Google suffered a significant loss in stock price following Bard’s rushed debut after the language model incorrectly said the Webb telescope was the first to Yakov Livshits discover a planet in a foreign solar system. Meanwhile, Microsoft and ChatGPT implementations also lost face in their early outings due to inaccurate results and erratic behavior. Google has since unveiled a new version of Bard built on its most advanced LLM, PaLM 2, which allows Bard to be more efficient and visual in its response to user queries.
The potential of generative AI and GANs in particular is huge because this technology can learn to mimic any distribution of data. That means it can be taught to create worlds that are eerily similar to our own and in any domain. We just typed a few word prompts and the program generated the pic representing those words. This is something known as text-to-image translation and it’s one of many examples of what generative AI models do.
As an evolving space, generative models are still considered to be in their early stages, giving them space for growth in the following areas. Generative AI is a powerful tool for streamlining the workflow of creatives, engineers, researchers, scientists, and more. Previous research areas include RPA, process automation, MSP automation, Ordinal Inscriptions and NFTs, IoT, and FinTech. The purpose of generative AI is to create content, as opposed to other forms of AI, which might be used for different purposes, such as analyzing data or helping to control a self-driving car. Are you looking to harness the potential of Generative AI, Machine Learning, and Deep Learning?
AGI is the ultimate realization of AI as it encompasses functions that the human brain can accomplish. It goes beyond narrow expertise and dives headfirst into the deep end of human-like cognitive abilities. AGI is the epitome of AI advancement, a grand vision where machines can conjure meaningful insights and responses, irrespective of specific input variables. Picture a world where an artificial intelligence (AI) system possesses the remarkable faculties of human thought, reasoning, perception, and inference. This is the awe-inspiring concept known as artificial general Intelligence (AGI).
Although they share similarities, understanding the differences between them allows us to appreciate the unique value each brings to the table. As AI continues to evolve, we can only imagine the technological breakthroughs that lie ahead. Conversational AI typically presents as a chat interface, while generative AI doesn’t have a standard user interface as its outputs can range from text to images, music, and beyond. Want to learn more about the future of artificial intelligence and hyperautomation? That said, the impact of generative AI on businesses, individuals and society as a whole hinges on how we address the risks it presents.


The Astronomy Group is furthermore part of the Centre for Exoplanet Science, which brings together researchers from different disciplines to find out how planets form in different galactic environments, how their atmospheres evolve, and the relation between the evolutionary history of planets and the emergence of life.
Andrew Cameron, Martin Dominik, Keith Horne
In St Andrews, we are currently carrying out experiments for detecting extra-solar planets based on two different techniques – transits and microlensing -, while also studying debris disks around nearby stars, which constitute candidate systems for the presence of planets. Our research featured in an exhibit “Is there anybody out there? Looking for new worlds”, which was concepted for the 2008 Royal Society Summer Science Exhibition.
Doppler surveys show that 1% of nearby main-sequence stars host “hot Jupiters” in 1-4 day orbits with radii less than 0.05 AU. 10% of those should have orbits close enough to edge-on for the planet to transit in front of the star. Transiting planets are uniquely useful because the drop in light level as the planet crosses the star gives us precise measurements of the planet’s radius. As a leading member of the UK SuperWASP project, we are conducting a wide-angle survey of bright stars for transits of large, short-period planets with two identical robotic observatories giving access to both the northern and the southern sky. Working in collaboration with the Geneva planet-search team in the southern hemisphere and the SOPHIE radial-velocity spectrometer team in the north, the SuperWASP team has discovered 60 transiting planets between 2006 September and 2011 August. We have been allocated time on the Hubble Space Telescope and the infrared Spitzer Space Telescope to make precise measurements of the sizes and atmospheric temperatures of many of these planets. Using the HARPS spectrometer on the ESO 3.6-m telescope, we have discovered that the orbits of many of these planets are strongly tilted or even retrograde relative to the stellar spin axis, providing important dynamical clues to their origins. Through SUPA-2, the University of St Andrews has contributed to the construction of the Geneva-led HARPS-North radial-velocity spectrometer, which was commissioned at the 3.5-m Telescopio Nazionale Galileo (TNG) on La Palma early in 2012. Its primary goal is to measure the masses of low-mass planet candidates discovered by the NASA Kepler mission, achieving long-term 1 metre per second median radial-velocity precision on V < 11-mag stars. Over the next five years (2017-2022) the programme will be renewed and expanded to characterise planets transiting brighter stars from the NASA TESS mission and the Swiss-led ESA CHEOPS satellite following their respective launches in 2018.
At any given time, only one in a million stars in the Galactic bulge is significantly brightened due to the bending of its light caused by the gravitational field of an intervening foreground star, a phenomenon known as (galactic) gravitational microlensing. However, daily monitoring of hundreds of millions of stars by survey teams (such as OGLE or MOA) results in about 1000 on-line alerts of ongoing microlensing events per year. A planet orbiting the foreground ‘lens’ star can reveal its existence by producing a brief deviation on the observed light curve, lasting from days for a Jupiter down to hours for an Earth. Since 1997, members of our group have been involved in the PLANET (Probing Lensing Anomalies NETwork) collaboration, which was the first systematic effort to hunt for extra-solar planets by means of high-cadence round-the-clock follow-up observations on ongoing microlensing events. While PLANET used a network of staffed 1m-class optical telescopes, we pioneered the use of 2.0m robotic telescopes with RoboNet-1.0 and now RoboNet-II, as well as the deployment of algorithmic schemes for optimal target selection and anomaly detection resulting in the ARTEMiS (Automated Robotic Terrestrial Exoplanet Microlensing Search) system. A fully-deterministic microlensing campaign with RoboNet-II and MiNDSTEp (Microlensing Network for the Detection of Small Terrestrial Exoplanets) will lead to a census of cool planets down to Earth mass and even below orbiting either Galactic disk and bulge stars, and thereby probe models of planet formation and orbital evolution in a region that is not reasonably accessible by any other means.
Radial Velocity Method
Scientists at St Andrews spent the last decade leading the ground-based discovery of hot Jupiters with WASP. NASA’s Kepler/K2 has since delivered large numbers of smaller planets with known radii. We now move from the discovery era into one of characterisation and trying to understand what sort of planets emerge from the formation process in different environments. HARPS-N is enabling us to measure their masses and hence bulk densities. A picture is emerging in which planets smaller than 1.6 Earth radii are predominantly rocky, while bigger ones have lower densities indicating deep water/ice mantles and extended gaseous atmospheres. NASA’s Transiting Exoplanet Survey Satellite (TESS) is similar in concept to WASP, using small wide-field telescopes, but in space. It will find many small planets transiting bright stars. We will weigh them with HARPS-N, and learn how easy it is for planets of different sizes to retain oceans and atmospheres under irradiation by their host stars. The ESA CHaracterising ExOPlanets Satellite will measure radii of small planets and phase curves for gas giants. Such phase-curve observations will inform and challenge the work done by our theoretical astrophysicists on the atmospheric structure of exoplanets.
The window into extrasolar planets are their atmospheres. Transition spectra, obtained with the Hubble Space Telescope and from the ground with super-sensitive instruments like FORS2 at the VLT, review the presence of clouds and of gaseous water in some of the extrasolar planets. We perform numerical simulations of exoplanet atmospheres in order to understand what these observations tell us, for example, about the gas chemistry and cloud formation. Researchers in St Andrews have pioneered the cloud formation modelling in exoplanet atmospheres. We simulate the formation of mineral and diamond clouds and their effect on atmospheres in order to understand the chemical diversity of extrasolar planets. Our work links laboratory work, quantum mechanical cluster calculation and large-scale atmosphere modelling in order to predict atmospheres on exoplanets. We are also interested in the occurrence of lightning and other charge-processes in such unusual environments. Lightning has been suggested as a possibility to initiate the chemical steps that led to the emergence of life on Earth.
Observations suggest that many hot Jupiters contain a large dust cloud component in their atmosphere because they obscure the absorption signatures of the atmospheric gas underneath the cloud layers. These clouds are made of mineral compounds such as TiO2[s], MgSiO3[s], SiO[s], Al2O3[s], Fe[s] ([s] meaning solid particles), and not of water like on Earth.

Since the late 90s, thousands of exoplanets have been discovered. These exoplanets show a large diversity in sizes, masses, even distances to the host star, much different to our Solar System planets: Jupiter-size planets orbiting other stars at the distance of Mercury; planetary systems with several planets inside the orbit of Mercury; terrestrial planets several times bigger than Earth, but still rocky and not made of gas. Could these planets host lightning in their atmospheres? Let’s look at Earth and Saturn. They have different composition, different sizes, masses, different atmospheres. And still, they both show lightning activity. So why couldn’t it occur on exoplanets?

Simulations of planet-forming disks help to disentangle observations from high-performance facilities like ALMA and and space missions like Herschel. We seek to understand the processes that set the initial conditions for planet formation in planet forming disks. Knowing that the solar system is unique, we aim to understand why so many other planetary systems are different from the solar system.

Here is a showcase of some finished projects/applications:


Many households, actually just about every household, have electronic devices that could be powered by solar power. Some of these devices consist of TV’s, DVD players/recorders, computer’s laptop and desktops, VCR’s, Stereo’s, and the list could go on and on, many have more than one. It is common to have two or even three of each, and still not be considered rich.Now, what if you could power these devices with electricity produced by you? What if you could produce enough electricity to power your whole house, would you do it? If your thinking it is not worth it because your electronic devices do not use a lot power then you really need to educate yourself on the amount of power these devices draw when turned off.Yes, even when shut off a lot these devices still draw power because they are not completely shut down, they are, basically, in a standby mode. Most electronic equipment requires power even after being shut off to keep the memory from being lost. (TV channels, radio station channels, even the internal clock) So, your electronic devices, even though shut off are drawing more power than you think.If you do not believe me then, for at least one month, unplug every electronic device when not in use, and only plug in the device when you are going to use it then, unplug it again after you turn it off. I know it is a pain to keep resetting everything but you will be amazed at how much it will lower your power bill.Making and installing solar panels to produce electricity to power these devices is not that hard or expensive if you do it yourself. If you install enough solar panels, you can harness enough solar power to power your whole house and have some left over.Guess what? That extra electricity you produce can be sold back to the money sucking power companies. Think about it, you can power your entire home using solar power, and if your solar power system is large enough, you can even put money back into your pocket by selling the excess. The best part is your house does not have to be huge in order to benefit from the use of solar power. The average size home has more than enough roof area to accommodate the necessary solar panels.


This is the time of cyber-stalking. Right now, as you stare at your device with cameras enabled and network ports open, with speakers powered and WiFi on, as handheld devices crisscross a mesh of public networks with interfaces readied to connect, and the use of routers sharing bandwidth between Ethernet and wireless interfaces proliferates, this is the moment of stalking and lurking, this is the time of cyber-crime.
The conditions that make this moment perfect for cyber-crime are not limited to the proliferation of devices populating the Internet of Things (IoT) or the near-global access to the Internet. Those conditions are human, both in the individual and the institutional sense.
The human tendency to disparage concerns that are neither personal nor immediate is an immense factor in the fact of cyber-crime. We have lost sight of privacy, the experience of an individual, interior world so significant that is considered a human right. Each day we carry our active personal devices through the public square, with each time we bring our personal devices of communication onto the networks of public and private corporations, we sacrifice privacy—our own, others’, and that of the corporate entity—to convenience and trend.

Digital Bolex D16 Camera test shooting
We’ve been very excited to have the Digital Bolex D16 camera with us. I’ll be uploading a more detailed Gear Guide video soon. But our initial impression is that this is a very exciting little camera to have around.
It shoots uncompressed 2K raw to an internal 500GB hard drive. It has a Kodak S16mm size sensor on a C-Mount, but we’ve switched it to the Arri PL mount. There is a very basic built in monitor screen that really is only enough to know you are pointing the camera the right way. It is not going to be for critical focus or exposure judgements. For that an additional monitor would be needed. But for running around and grabbing some quick things you can get by without it. It also has proper XLR audio inputs and a 12V output for driving that external monitor. The internal battery can last for hours.
So this bit of test shooting was with a mixture of a Dalsa Leica 100mm pl mount lens, and then a Cooke S4 9.5mm lens for the wides.
We processed the raw DNG footage through Davinci Resolve 11 with a custom LUT. Without external monitoring like an EVF or additional LCD it was perhaps a bit too easy to overexpose and clip the blue and green channels, leaving pink highlights. And there are some metadata issues to be resolved in the raw workflow. Adding Reel Names into the raw metadata will help conform back from offline edits.
But the Digital Bolex is going to be an exciting additional tool to the film-maker’s pallette with the rich colours possible from the Kodak chip.
And the camera is available to rent and hire through the Gear Factory in London

With the release of the electric car came the release of many new questions. Is the electric car good for long drives? How does it run? Will I be getting my money’s worth from investing in one? Many people have been thinking of trying it out, but are unsure of what problems or advantages it holds. Here are 3 pros and 3 cons that you should know before deciding to purchase an electric car.
Electric cars are not much more expensive than regular cars. In fact, if you are in the position of purchasing a new regular car, chances are you can afford an electric car. There are many electric cars that sell for an affordable price, thus more accessible and budget-friendly to more people.
The maintenance of electric cars is easier to handle than regular cars. Because of the electric carâ€™s usage of battery, its components have much less room for failure. The parts within the electric car function and move more simply.
3. Fuel Economy
You can easily charge your car at home. Electric cars don’t need fuel, so you can expect to make less frequent stops to the gasoline station. You only have to plug your car into a charging port and let it stay overnight, as simple as charging your phone or gadget.
1. Battery Malfunctions
Electric cars have limitations. Batteries tend to suffer through cold weather, and since electric cars make use of lithium batteries, your car could become less efficient. This means that your battery will run out much more rapidly than it normally would in warm weather.
2. Expensive Batteries
The batteries are expensive. Seeing that batteries are the main factor that make electric cars unique, the batteries needed to run and maintain them are quite pricey. The batteries needed are much bigger than regular smartphone batteries, and they are also more complex. Because of this, batteries are in fact the most expensive component of an electric car. Additionally, in the event of a battery failure, you will simply have to replace it.
3. Few Charging Stations
Charging stations are scarcer. If you find yourself traveling long distances, then the charging time you provided your electric car overnight might not cut it. If you end up driving too far from your home and in need of some more power to get back home, you might be in a difficult situation. Cities have yet to establish an adequate amount of charging stations for electric cars.
