Paul Robinson and Emily Paluch are the 2016 Elmer Carvey Memorial Scholarship Winners!
The winners of the 2016 Elmer Carvey Scholarship are Paul Robinson, an undergraduate majoring in Physics, and Emily Paluch, an undergraduate student majoring in Materials Science and Engineering. Both are attending University of California, Los Angeles.
Mr. Robinson is conducting research in Professor Anastassia Alexandrova’s lab in the Department of Chemistry and Biochemistry, where he has worked for the past two years, starting in his freshman year. He has concentrated on theoretical calculations of chemical bonding in materials. His first project – conceived by him – involved the effects of high pressures on bonding in molecules. After mastering quantum mechanical calculation computer programs based on density functional theory, he rapidly achieved results and published a paper as the primary author (see P.J. Robinson and A.N. Alexandrova, Assessing the bonding properties of individual molecular orbitals, J. Phys. Chem. A, 2015, http://pubs.acs.org/doi/abs/10.1021/acs.jpca.5b09687).
After his initial success, he has developed collaborations with the Tolber and Kaner labs at UCLA, where using theoretical calculations, he analyzed and predicted new, industrially useful, super-hard tungsten borides to be evaluated in the laboratory. The goal is to “fix” the super-hard materials in silico and guide synthesis to create metals rivalling diamond’s hardness. Mr. Robinson also has developed a collaboration with the Bowne and McQueen research groups at Johns Hopkins. The work has involved developing candidate materials for hydrogen gas storage. In this collaboration he has also elucidated the electronic structure of samarium hexaboride, which will be used to make quantum-computing circuits.
Mr. Robinson has attained numerous honors, including becoming an Eagle Scout. He has a total of two publications, with several more in preparation, and has made two presentations at scientific conferences. In addition, he has maintained an excellent academic record.
After graduating in 2018, Mr. Robinson plans to attain his Ph.D. in theoretical chemistry, focusing on designing and tuning the properties of materials. He would like to work on cross-disciplinary problems including superconductivity and the electronic structure of rare-earth materials.
Ms. Paluch has been performing research in Professor Mark Goorsky’s lab in the Materials Science and Engineering Department at UCLA for the last two years. The thrust of her research is to identify a viable material and processing technique for producing high-efficiency antireflective coatings for thin-film silicon solar cells. She has identified porous silicon as the material of choice for the antireflective coating. She successfully produced and characterized samples that have yielded surface reflections of approximately 7%, which is a significant reduction in reflectivity when compared to bare silicon which reflects approximately 30% of incident light. Ms. Paluch has experienced several challenges during the development of this new material solution, including finding a way to control the electrical current of the power source during electrochemical etching of the porous silicon.
She is also beginning an internship with Rayton Solar, a start-up solar cell company headquartered in Santa Monica, CA. There she will apply lessons-learned from her research to an industrial environment. In addition to her success in the laboratory and in industry, she is also the President of the Society of Women Engineers at UCLA for the coming year. She has also maintained a laudable academic record.
After graduating with her B.S. degree in 2017, Ms. Paluch plans to obtain an M.S. degree in materials science and engineering with an emphasis on electronic materials. Her career goal is to work at a solar cell company, performing research and development on ways to improve efficiency and reduce cost.
The Elmer Carvey Memorial Scholarship was established in honor of Elmer Carvey, an active member of the SCCAVS from 1964 until 1982. The Scholarship is awarded to undergraduate students attending public, four-year colleges in California who are planning careers in areas of interest to the society, which include vacuum-related technologies, surface and thin film science, nanotechnology, the understanding of materials properties, and the development of new materials. The stipend is $1,500.00 for one year.

New system developed at the Oxford University Hospitals (OUH) NHS Foundation Trust can maximise efficiency of clinical practice
[Oxfordshire, UK] An IT system developed by Oxford University Hospitals (OUH) NHS Foundation Trust can reduce the time used to input patient information by nearly 30%, a study published this week in the Journal of the American Medical Informatics Association shows.
“Our results suggest that introduction of an e-Obs system could lower nursing workload as well as increase documentation quality,” the authors, some of which were also involved in the design of the project, write.
The System for Electronic Notification and Documentation (SEND) has now been fully deployed at the trust, helping nurses add information about a patient’s vital signs through a tablet, which can then also be incorporated into the EPR system.
The data is connected through barcoded wristbands that help identify patients, alerting clinicians faster in case a patient is in serious risk of deterioration.
OUH reveals that each ward benefits from six ‘tablet computers’; the study was conducted between November 2014 and December 2015 across three wards in the Churchill and Horton hospitals.
It was recently announced that the system, along with two other digital health technologies, will also be deployed across four other NHS trusts this year.
“SEND, GDm-health and EDGE-COPD, demonstrate the benefits of the multi-disciplinary collaboration we have developed over the past decade in Oxford,” said Professor Lionel Tarassenko, Head of Engineering Science at Oxford University.
Reducing error risks
The system was initially deployed at the trust through the Department of Health’s Safer Hospitals, Safer Wards NHS Technology Fund as it was believed that difficulties in calculating risk scores or ‘illegible handwriting’ could lead to ‘misinterpretation’ of notes when it comes to patient information:
“SEND incorporates a number of features designed to reduce errors. In common with other e-Obs systems, SEND automatically calculates EWS (Early Warning Score) scores, thereby eliminating EWS calculation errors,” the study states.
Although the incorporation of technology into healthcare systems has been met with ‘mixed success’ in the past, efficient management of workload can now be cited as an immediate benefit for both staff and patients, advancing digital agendas for NHS trusts.
“The results of this study, taken in conjunction with previous work, supports the assertion that a well-designed system can save significant time in clinical practice. These time savings, in addition to the data quality benefits of electronic systems, present a convincing case for the adoption of e-Obs systems as part of routine inpatient care,” the authors conclude.


This instructable will show you how to make a web-connected mailbox sensor. Besides emailing you when your http://mailboxsensor.com/ is opened, it will also signal a Raspberry Pi sitting in your house to play an audio announcement. There is also a web-accessible Android/iPhone interface for you to check what time mail was delivered, as well as display the battery voltage left on the sensor.
But this could also easily be used as a web-connected security system, one that both plays an audio alarm in your home and emails you when the someone breaks into your house.
Under normal use (a few door openings per day), the battery powered mailbox Arduino should last over a year on a set of 4xAA batteries. The mailbox sensor has a range of over 700 feet through multiple walls, so this should work for most situations.
One strip board Arduino, circuit optimized for low battery power consumption
Strip board components (voltage regulator, capacitor, resistors, etc…), see details later on.
Two wireless transceivers (RFM69HW)
Two Arduino Uno’s with selectable 3.3V/5V switch for the gateways
One Raspberry Pi, but could be replaced with your PC/Mac if you don’t mind running the computer 24/7
I’ll explain how to piece all these parts together and provide all the code needed.
The simple setup should not consume a lot of power, but the Xbee could, so the idea from this guy was to cut the Xbee power when it’s not sending anything, and only power it up when you need to send something (BTW, that implies one-way communication, which I don’t like since I want to be able to reset the mailbox not only with the key, but also remotely, but I will try to achieve this on a further version of the sensor). Another tip from that same post to save some power, was to put the processor to sleep when is not doing anything. Basically the atmega328 has the capability to be put to sleep, and be woken up by interrupts in two pins (2 and 3). More information about this here.


Best Paper Award at PPAM 2022 for MD-Bench
We are pleased to announce that the paper “MD-Bench: A generic proxy-app toolbox for state-of-the-art molecular dynamics algorithms” by Rafael Ravedutti Lucio Machado, Jan Eitzinger, Harald Köstler, and Gerhard Wellein just received the best paper award at PPAM 2022, the 14th International Conference on Parallel Processing and Applied Mathematics, in Gdansk, Poland.
In this paper, Rafael presented MD-Bench (https://github.com/RRZE-HPC/MD-Bench), a proxy-app for short-range molecular dynamics (MD) algorithms. In contrast to other proxy-apps in this domain, MD-Bench includes algorithms from multiple major MD community codes and focuses on a simple and transparent implementation, which makes it well suited for research, teaching, and of course for benchmarking.
The paper described features and benefits of MD-Bench and illustrates its use-cases on three examples: an assembly analysis showing how the compiler-generated code can be improved, an investigation of memory latency contributions in a classical material science MD test case, and a systematic compiler code quality study based on hardware performance counter measurements.
PhD Student Rafael Ravedutti Lucio Machado is a liaison scientist at NHR@FAU and works on performance engineering for classical MD applications.
A preprint of the paper is available at arXiv:2207.13094.


I first heard the standard joke about fusion as an undergraduate physics student in the 1960s: Fusion power is fifty years away – and probably always will be.
More than fifty years later, we still don’t have fusion. That’s because of the huge experimental challenges in recreating a miniature sun on earth.
Still, real progress is being made. This month, UK fusion researchers managed to double previous records of producing energy. Last year, American scientists came close to ignition, the tantalising moment where fusion puts more energy out than it needs to start the reaction. And small, fast-moving fusion startups are making progress using different techniques.
A limitless, clean source of baseload power might be within reach – without the nuclear waste of traditional fission nuclear plants. That’s good, right?
Not quite. While we’re closer than ever to making commercial fusion viable, this new power source simply won’t get here in time to do the heavy lifting of decarbonisation.
We are racing the clock to limit damage from climate change. Luckily, we already have the technologies we need to decarbonise.
How much progress is being made on fusion?
Five seconds. That’s how long the UK’s Joint European Torus was able to sustain a fusion reaction, producing enough energy to run a typical Australian household for about three days. That’s a small fraction of the energy needed to make the fusion reaction happen, which used two 500 megawatt flywheels. That amount of power would meet the peak needs of 100,000 average Australian households. So we are still a long way from getting a net energy benefit from fusion.
On a technical front, achievements like this are incredible. Nuclear fusion is the process that powers stars like the sun, and we are working to harness this for our own use.
Read more: Nuclear fusion: how excited should we be?
At very high temperatures, light atoms such as hydrogen can combine to produce another element such as helium, releasing enormous quantities of energy in the process.
In the sun, these fusion reactions take place at temperatures about 10 million degrees. We can’t do it at that temperature, because we don’t have access to the enormous gravitational pressure at the centre of the sun.
To achieve fusion on earth, we need to go hotter. Much hotter. Experiments like the one in the UK are able to superheat a body of gas called a plasma to inconceivable temperatures, reaching as high as 150 million℃. The plasma has to be confined by incredibly strong magnetic fields and heated by powerful lasers.
This temperature is far hotter than anywhere else in our solar system – even the centre of the sun.
While the recent progress represents a major step forward, sober reflection suggests the dream of limitless clean energy from hydrogen is still a long way off.
On the megaproject front, the next step is the International Thermonuclear Experimental Reactor (ITER) being built in southern France. Far too big for any one country, this is a joint effort by countries including USA, Russia, China, the UK and EU member countries.
The project is enormous, with a vessel ten times the size of the UK reactor and around 5,000 technical experts, scientists and engineers working on it. Famously, the project’s largest magnet is strong enough to lift an aircraft carrier.
Even this enormous project is only expected to produce slightly more power than it uses – around 500 megawatts. The first experiments are expected by 2025.
To me, this illustrates how far away commercial fusion really is.
Fusion won’t get here in time
It will take decades yet to go from these promising experiments to a proven technology powering modern society. That means it simply will not get here in time to make a real contribution to slowing and reversing climate change.
To have a decent chance of keeping climate change below 2℃, we have to get to net zero emissions worldwide in under 30 years.
We can’t wait. We have to decarbonise energy supply and energy use as quickly as possible.
Many countries are already moving at speed. The UK is planning to get to zero-emissions electricity within 12 years. States like South Australia and New South Wales should get there around the same time. The International Energy Agency predicts renewables will become the largest source of electricity generation worldwide by 2025.
The shift away from baseload
Even if fusion arrives, it would face major challenges due to the cost of the plants and the changing nature of the grid.
In the second half of the twentieth century, power stations became larger to achieve economies of scale. That worked, until recently. Only ten years ago, large coal-fired or nuclear power stations produced cheaper electricity than solar farms or wind turbines.
This picture has changed dramatically. In 2020, global average prices of power from new large wind turbines was 4.1 cents per kilowatt-hour, while solar farms were even cheaper at 3.7 c/kWh. The average for new coal? 11.2 c/kWh.
Ever more favourable economics drove a massive investment in renewables in 2020: 127 gigawatts of new solar, 111 of new wind and 20 of hydro-power. By contrast, only 3GW of net nuclear power came online, while coal-fired power actually dropped.
As a result, we’re seeing a global shift away from old models of baseload power, where power is generated in large power stations and transported to us by the grid.
These shifts are driven by cost. The price of electricity from renewables is now falling below the running costs of old coal-fired or nuclear power stations. Coal power requires digging the stuff up, transporting it, and burning it. Renewables get their power source delivered free of charge.
The idea of fusion power is alluring. There’s a real appeal in the idea we could replace large coal and gas stations with one large clean fusion power plant. That, after all, is the selling point of the International Thermonuclear Experimental Reactor: to produce baseload power.
But will we need it? The pattern of power supply is changing. The massive take-up of solar power by households means we have now permanently shifted from the old model of large power stations to one where supply is distributed around the network.
It will be a technological marvel if we are finally able to build fusion plants in the second half of this century. It’s just that they won’t be in time.
Luckily for us, we don’t need fusion. We already have what we need.

Optimized for lower capacity, low inertia loadsMatch the general-purpose workhorse of the Yaskawa servo line with a custom designed gearhead that enhances its versatile performance. S7J was optimized by servo application professionals for Yaskawa SGM7A servo motors, and maximizes their ability to produce a high rate of power at extremely low levels of inertia. The same durable gear motor is able to transfer the servo system’s high torque performance with an application requires it.
Strong Performance for High Power DemandsLarger automation components are suited to the extra robust performance of S7G, designed for use with the Yaskawa SGM7G family of rotary servo motors. A full series of gearheads was designed to maximize the space-saving profile of 7G motors, while delivering high torque, consistent positional accuracy and maximum responsiveness to extreme changes in speed demand.
Optimized for Load Matching SuccessGet maximum responsiveness from a gear motor engineered to match one of Yaskawa’s most versatile servo systems. The S7J was designed to extend the performance of Yaskawa SGM7J servo motors, a series known for maximum responsiveness in applications requiring precise load matching. S7J provides gear ratio options to 50/1 for precise motion in low capacity applications, while assuring world class accuracy at rated speeds to 3000 rpm and torque ratings up to 2.39 N-m (21 in-lb).
High Torque, Low RPM Performance In a Compact SpaceAdd the advantages of a gearhead to a servo motor optimized for space savings. Yaskawa created the S7P to maximize the advantage of SGM7P servo motors, which pack full torque and speed performance into a motor reduced in length by 25%. This puts world-class speed control and positional accuracy into less space than ever before, allowing machine designers to develop more compact and efficient products.
By means of the modular and extremely compact SLIO the realization of almost every automated solution will from now on be simpler and especially more economical. SLIO can be combined and applied with each of the established systems 100V, 200V, 300S, 500S. It´s one of the most effective and modern decentralized I/O systems available on the market. It combines high functionality with a clever mechanic concept in an extremely compact design.
In 1997, Yaskawa released the SS5 Series which featured the world's first PM motors with permanent magnets built directly into the motors. The overwhelmingly high efficiency of these motors made machine downsizing and saving energy possible. Over the years, the need to reduce CO2 emissions has continued to increase, and in response, Yaskawa Motor Corporation has undertaken a new challenge to develop original technologies that will help protect the future of our planet. In response to the introduction of high efficiency standards for industrial motors in 2015 to help reduce CO2 emissions, Yaskawa motor corporations has released the SS7 Series, which improves on the efficient and compact SS5 series. The SS7 Series of Eco PM motors promises to meet all your needs in a wide range of applications.


We are the only shop with in 1000 miles that seperates iPhones screens allowing us to keep original Apple parts. We do this and we do this in house. We carry a huge selection of certified pre owned iPhones with warranties.
We keep Original Apple LCDs. Here’s why:
- LCD vs. TFT The primary difference between low quality LCD screens and high quality LCD screens is the type of technology used. There are two primary types of LCDs, IPS (inpanel switching) and TFT (thinfilm transistors). IPS is the latest LCD technology and provides wider viewing angles, richer color, and better contrast. This is the same technology Apple uses in the iPads, iPhones, and iPods. TFT is a technology that is typically used in older LCD panels and does not offer the same quality as IPS panels . TFT is used by most third party manufactures due to its low cost .
- Weak Glass The glass used on the A/A- replacement screens is, in most cases, either thinner or un-tempered (tempering a a process used to harden glass.. , often both. They break much easier, we know from experience, causing you to need another iPhone screen.
- LCD Flex Cable and Copy Digitizer It may not seem like a big deal to have an aftermarket cable running from the iPhone replacement to your iPhone motherboard but it is. Often times this result in slightly slower performance, lower sensitivity to touch, all while consuming more battery.
- Aftermarket Back Light perhaps the easiest to spot as you iPhone will no longer be as bright or have a slight hue that was not their before, common hues blue and yellow. If that was not another, this is another way an aftermarket screen will effect battery life and performance
- Weak Glue Attaching the Plastic Frame Manufactures will save pennies to put less glue or use inferior glue to connect the plastic frame to the lcd assembly, when you make millions of iPhone replacement screens even a cent will add up, resulting in the already fragile glass to separate from the housing. This will happen on occasion for both qualities but is more common with the lower quality for the obvious reasons.
- Quality Control Tests Another reason these screens are so inexpensive is that when a manufacture is testing the quality of each screen, they find minor defects (dead pixel, small dead spots on the digitizer) or they are determined by the machine to be at a significantly higher risk for malfunction in the future.


Here’s an article I wrote two times. once in french and once in english. Therefore, I hope to give an answer to that recurrent problem on the internet. I spent a lot of time searching without finding any clear answer.
I had a few weeks ago some problems with my Bluetooth card in my computer. I was encountering constant disconnections no matter which OS i used. To be sure the problem wasn’t due to my mouse controller, i tested with other devices and nothing changed. After a chaotic return at the customer service (the first time my computer had to be in an intern’s hands) my laptop came back functional.
But this morning, a simple boot on my Windows was enough to fail all my communication devices (Wifi, Ethernet, Bluetooth). After a short reboot on Ubuntu to be sure the problem was due to the drivers and not to the devices, I uninstalled every devices with the device manager (Right clic on Computer -> Manage -> (on the left) Device manager -> Right clic on every problematic device -> Uninstall)
Once every driver uninstalled, i rebooted to let Windows use generic drivers. I downloaded then the offical drivers on the Asus website and installed them one by one.
After an other reboot, the Internet connection was back but the Bluetooth still wasn’t functional. I uninstalled an other time the Bluetooth drivers and I rebooted again. The Bluetooth was back but with generic drivers. The connection with my Bluetooth mouse was enabled but wonky and had deconnections.
A last installation of the Bluetooth Driver and a last reboot let me finally have a functional Bluetooth card.
A last problem persisted. The mouse had deconnections like before but the problem wasn’t present on Ubuntu. I had to go in the bluetooth card properties and Right clic -> Properties -> Power managment tab -> Uncheck « Allow the computer to turn off this device to save power ».
After all those annoying steps, here i’m back with my Logitech V470 Bluetooth Mouse connected to my Asus G73JH on Windows 7 with no Bluetooth dongle or other trickery.


ZUG, Switzerland – November 17, 2020 –Bitcoin Association, the Swiss-based global industry organization that works to advance business with the Bitcoin SV blockchain, today announces the release of three software packages designed to restore and enhance true peer-to-peer functionality on the Bitcoin network.
All three versions, Bitcoin SV Node v1.0.6, mAPI v1.2.0 and SPV Channels CE v1.0.0 software collectively provide all the tools needed to implement peer-to-peer and payment verification workflows. simplified (SPV) on the client side. . These allow participants in the Bitcoin network to transact directly with each other, as Satoshi Nakamoto envisioned when he called Bitcoin a “peer-to-peer electronic payment system” in the title of his famous white paper. With new versions of the software, recipients are able to prove the veracity of funds sent without the need to scan the entire blockchain using the properties of Merkle evidence – only miners running the full node implementations used to form the settlement layer, facilitating full peer-to-peer functionality while maintaining the safety and security that Bitcoin offers.
The versions also have the effect of dramatically reducing the technical requirements to participate in the Bitcoin network, with users or devices able to implement a client model and only interact with blockchain transactions applicable to them, rather than to have to review the entire Bitcoin transaction history. By reducing the requirements to participate in the Bitcoin network, today’s releases introduce a range of new use cases for Bitcoin, with thin clients for devices such as those used on the Internet of Things (IoT) now. achievable.
You can find full details on all three releases today in the release notes on bitcoinsv.io.
Speaking on today’s posts, Steve Shadders, CTO of the Bitcoin SV infrastructure team, commented:
“Today’s set of releases is an extremely important step in restoring Satoshi Nakamoto’s vision for Bitcoin, as they finally allow users to interact with Bitcoin in the simplified payment verification way described in the original Bitcoin white paper. Prior to today’s releases, the full suite of tools needed to enable a true SPV did not exist, which encouraged users to run unnecessarily cumbersome client implementations. Starting today, users will be able to run thin clients to interact with the Bitcoin blockchain, while benefiting from all of the built-in security guarantees provided by Bitcoin.
Also commenting, Jimmy Nguyen, founding president of the Bitcoin Association, said:
“The advent of true peer-to-peer transactions in today’s version further strengthens Bitcoin’s ability to serve as a large-scale global distributed data and payment network. With the range of new use cases unlocked through SPV payment channels, I’m excited to see how developers and innovators are putting these features into practice, and the new business models that will follow.

The Vaporesso Gen Mod has landed in New Zealand and is now available at Vapoureyes. The Gen makes use of Vaporesso's new AXON chip, which is packed full of some really great features.
Sure, it has all the standard features you've come to expect from a quality brand like Vaporesso, the new AXON chip has Smart Temperature Control, an ECO mode and a DIY mode (it 's you customise a power curve). It's pretty cool because it's all done via a fantastically simple UI - but, who cares about all of that. Everyone at the Vapoureyes office is raving on about the new Pulse mode.
So, what is pulse mode? Put simply, as you hold down the power button and fire your mod - power delivery to your atomiser happens in bursts every 20 milliseconds. So in a single second, the AXON chip fires 50 times. It's practically pulsing at 50Hz, which is so cool because to the human ear at that frequency - it sounds like a continuous tone! Now, while your ears might not notice the pulsing as it happens so quickly - one thing you'll definitely notice is your batteries lasting longer!
- Display: 0.91' OLED screen
- PULSE MODE (deserves it's own line)
- ECO, DIY and Smart Temp Control Modes
- Charge Current: 2.5A
- Battery: 2x18650 (Not Included)
- Output Wattage: 5-220W
- Resistance Range: 0.03~5Ω
What's in the box:
- 1x GEN MOD (DID I MENTION IT DOES PULSE MODE, GUYS?)
- 1x USB Cable
- 1x User Guide
- 1x Warranty Card


The recent growth of the blockchain technology market puts its main cryptocurrencies in the spotlight. Among them, Ethereum stands out due to its virtual machine (EVM) supporting smart contracts, i.e., distributed programs that control the flow of the digital currency Ether. Being written in a Turing complete language, Ethereum smart contracts allow for expressing a broad spectrum of financial applications. The price for this expressiveness, however, is a significant semantic complexity, which increases the risk of programming errors. Recent attacks exploiting bugs in smart contract implementations call for the design of formal verification techniques for smart contracts. This, however, requires rigorous semantic foundations, a formal characterization of the expected security properties, and dedicated abstraction techniques tailored to the specific EVM semantics. This work will overview the state-of-the-art in smart contract verification, covering formal semantics, security definitions, and verification tools. We will then focus on EtherTrust , a framework for the static analysis of Ethereum smart contracts which includes the first complete small-step semantics of EVM bytecode, the first formal characterization of a large class of security properties for smart contracts, and the first static analysis for EVM bytecode that comes with a proof of soundness.
This paper focuses on the smart contract of Ethereum, which indirectly controls ETH. Ethereum smart contracts are written in a Turing complete language, so it's complex at the semantic level. This paper discussed in detail the foundations of EtherTrust, it’s the first sound static analyzer for EVM bytecode. In my opinion, this paper plays an important role in learning the security of smart contracts.
As we all know, smart contracts are extremely important for Ethereum. In this paper, it first overviewed the formal verification approvals, then presented a systematization of the state-of-the-art in Ethereum smart contract verification and outlined the open challenges in this field, and it discussed in detail the foundations of EtherTrust, it also reviewed how the small-step semantics presented. Finally it presented how single-entrancy a relevant smart contract security property is expressed in terms of queries, which can be then automatically solved leveraging the power of an SMT solver. This paper has made a great contribution to the security of smart contracts.

Wind & Weather 2.0
WindShape offers solutions for testing drone aerodynamics and controls. The increasing number of drones in professional activities drives drone manufacturers to constantly improve the reliability, robustness and stability of their flying machines.
Currently, there is no solution for testing drones in various wind/weather configurations. Due to the lack of testing solutions, manufacturers have no choice other than going outside to test their drones. This testing methodology, suffers from many drawbacks, including poor accuracy and repeatability, dependence on day-by-day weather forecast, unknown and non-controllable flow conditions, short test times, large distance between drone and tester, etc.
WindShape has the solution to this problem: a wind & weather simulator for testing drones in various and controllable atmospheric conditions, including arbitrary wind speed, temperature and direction (even vertical flow for simulating landing/descent configurations), as well as turbulence, hail, gusts, rain, and sandstorms.
Target clients are drone manufacturers, pilots (training and license), academic researchers, drone certification and standardization bureau (ISO, FAA), inspection authorities (drone periodic check-up and maintenance).
Wind & Weather Facility
WindShape wind facility offers new solutions for testing autonomous systems by combining new technologies.
The wind facility consists of an array of a large number of fans (approximately 150 powerful fans per square meter).
Drone Certification & Standardization Tool

The Weather & Chaos project of the University of Maryland, College Park (UMCP) was started by Distinguished Professor Eugenia Kalnay of Department of Atmospheric and Oceanic Science and Distinguished Professor Jim Yorke of the Institute for Phyical Science and Technology in 2000. They assembled a group of experts to carry out interdisciplinary research in numerical weather prediction, dynamical system theory and scientific computation. The goal was to conduct research that would lead to a better understanding of the behavior of high-dimensional spatio-temporally chaotic systems, such as the atmosphere, and to improved techniques for numerical weather prediction. The initial funding for the project was generously provided by the W. M. Keck Foundation.
Since it was launched in 2000, the project has grown into a major informal research and educational program at UMCP.The project has led to the publication of many papers in leading atmospheric science and physics journals and to over a dozen Ph. D. dissertations in the Atmospheric and Oceanic Science, Physiscs, Mathematics, Applied Mathematics and Scientific Computation and Electrical Engineering doctoral programs .
The most important product of our research efforts is the Local Ensemble Transform Kalman Filter (LETKF; Hunt et al. 2007) data assimilation system. This system allows for the estimation of the state of large spatio-temporally chaotic systems, such as the atmosphere, based on incomplete observations and a possibly imperfect numerical model of the system. In addition to the UMCP scientists involved in the project, scientists from the Arizona State University, Tempe, AZ and the George Mason University, Fairfax, VA have also made important contributions to the development of the algorithm and the computer code. The LETKF has been successfully tested on the Global Forecast System model (GFS) of the National Centers for Environmental Prediction/National Weather Service (NCEP/NWS) on the Regional Spectral Model (RSM) of NCEP/NWS, on the Finite-Volume Global Circulation Model of the NASA Goddard Space Flight Center and on a numerical model of laboratory convection. Current efforts of the Weather and Chaos Project include implementation of the LETKF on the Geophysical Fluid Dynamics Laboratory Mars General Circulation Model (GFDL Mars GCM), in collaboration with NOAA GFDL, Princeton, NJ and the Atmospheric and Environmental Research Inc., Lexington, MA and the development of an LETKF-based system for the coupled assimilation of weather and carbon observations to study the carbon cycle in the Earth system, in collaboration with the University of California, Berkley, CA and the Lawrence Livermore National Laboratory, Livermore, CA of the Department of Energy. The LETKF has been adopted as the next operational global data assimilation system system by CPTEC (Center for Weather prediction and climate studies of Brazil) and is being tested at the Japanese Meteorological Agency. The LETKF is also being tested for coastal limited area data assimilation with an implementation on the Estuarine and Coastal Ocean Model (ECOM) by AER Inc, It is implemented into the Regional Ocean Modeling System (ROMS) on California coastal ocean dnd the Chesapeake Bay in collaboration with University of California, Los Angeles. A computationally highly efficient parallel FORTRAN code is available for download.


Dyson's investments in healthier, more hygienic technology date back more than 25 years, when the company started developing filtration systems for vacuums to capture allergens, dust and bacteria. With today's announcement, Dyson builds on its longstanding investments and makes it easier than ever to have a clean home2.
The new Dyson Cyclone V10 TM cord-free vacuum is built around the Dyson digital motor V10. The new motor allowed Dyson engineers to rotate the cyclones and bin assembly through 90 degrees, into an in-line format. The resulting linear airflow path improves the number of Air Watts of suction by 20% compared to the Dyson V8 TM cord-free vacuum cleaner. It also allows a "point and shoot" bin emptying mechanism for ease of use. And with an optional 40% bigger bin capacity, you can clean more of your home and empty less. Floor to ceiling. Then out to the car.
James Dyson said: "A strong performing machine starts with an efficient motor. The Dyson digital motor V10 is Dyson's most advanced. It has enabled us to entirely change the format of a vacuum cleaner, and to achieve Dyson's best ever cord-free machine performance. The Dyson Cyclone V10 TM vacuum is so light, so powerful, it can deep clean anywhere in your home, on any floor type. It is the reason I've stopped developing full-size vacuums."
Through extensive research and at-home trials over the years, Dyson learned that people often believe they need a big machine to properly clean their home and "get the job done". With the Dyson Cyclone V10TM cord-free vacuum, this is no longer the case — with the suction power of a big machine3, and an optional bigger bin size, you can have the best technology, plus the added convenience of a light, cordless machine.
Separation: Fourteen cyclones are precisely arranged around the central axis of the machine, enabling the airflow inside each cyclone to travel at up to 120 miles per hour, generating over 79,000G, separating even microscopic dust from the air efficiently.
Other cyclonic vacuums can be inefficient. Dust and dirt is not efficiently separated from the airflow so it instead ends up on the filter where it chokes the airflow from the motor.
Filtration: Dyson engineers have wrapped both the pre- and post-motor filters around the motor as one sealed unit for improved filtration, capturing 99.97% of allergens as small as 0.3 microns – thus releasing cleaner air.
Other vacuum cleaners can expel dust, allergens and bacteria into the air you breathe.
To help keep the filter in top shape, a new filter sensor will alert owners, via an indicator light, when it's time to wash the filter.
Energy Storage System: Dyson engineers wanted to deliver enough power to the fast spinning Dyson digital motor V10, while also extending the runtime. So they developed a more energy-dense battery, without any additional weight. Along with improved electronics and battery system management, the new Dyson Cyclone V10TM cord-free vacuum has up to 60 minutes of fade-free power. And it charges in just 3.5 hours. As with other Dyson cord-free vacuums, the machine has a trigger, rather than an on/off switch, – the moment you pull the trigger, the motor starts and accelerates to operating speed in a fraction of a millisecond.
Cleaner heads: The machine offers two cleaner heads, one for hard floors, the other for carpets. Both have powerful motors located inside the brush bar. One removes large debris and fine dust from hard floors simultaneously using a larger roller covered in soft woven nylon and anti-static carbon fibre filaments. The other drives stiff nylon bristles deep into carpet pile to remove ground-in dirt and pet hair, and it features three settings so owners can choose between greater pickup of fine particles or allow for larger debris.
Availability: The Dyson Cyclone V10TM vacuum starts from $499.99 and is available at Dyson Demo stores in New York, San Francisco, and Tysons Corner, VA, as well as www.dyson.com starting March 6th, and Best Buy, Bed Bath & Beyond, Target, Amazon, Nebraska Furniture Mart, Abt, and Video Audio Center (and their associated websites) starting March 13th. The machine includes a 2 year hassle-free warranty on parts and labor. Additional tools can be purchased from the Dyson website.
Paul Dawson, Vice President for Dyson Health and Beauty, said: "At Dyson we develop machines for real people and real homes, creating technology that works well in the test lab but more importantly doing what they're expected to do in a real-world setting. To clean the air at home, a purifier needs more than a filter. It needs to automatically sense pollution, capture gases and ultrafine particles, and project clean air to every corner of the room. The Dyson Pure Cool™ purifying fan does all of this."
Most of the air we consume is indoors where we spend 90% of our lives, but it can contain microscopic particles which are invisible to the human eye. The World Health Organization has published guidelines for indoor air quality and fact sheets on household air pollution and health, and a study recently published by Science revealed that common household items such as soap and cosmetics can cause as much pollution as cars.
Air pollution is a global conversation, and as awareness rises, attention is moving from outdoor air quality to indoor.
Sensing: A new LCD display shows which particles and gases the Dyson Pure Cool™ purifying fan is automatically sensing in real time. A unique Dyson algorithm processes the input from three sensors and then displays air quality readings.
Lasers measure and identify ultrafine particles. A separate sensor detects the amount of VOCs (Volatile Organic Compounds, such as benzene and formaldehyde, emitted from paint, burning candles and materials in furniture) and NO2 present. A third sensor measures relative humidity and temperature.
Capturing: An improved filter in the new Dyson Pure Cool™ purifying fan captures both particulate matter and gases. Dyson engineers have incorporated 60% more HEPA media into a taller and deeper filter, and they've introduced three times more activated carbon, which can absorb gases, odors, domestic fumes and VOCs.
Nine meters of condensed and sealed borosilicate microfiber filters capture 99.97% of particle pollution as small as 0.3 microns, including allergens, bacteria, pollen and mold. Activated carbon filters, which have been coated with Tris (Trishydroxymethylaminomethane) to increase the absorption efficiency, remove gases including NO2, formaldehyde and benzene.
Projecting: The Dyson Pure Cool™ purifying fan is the only purifier with Air Multiplier™ technology and 350⁰ degree oscillation, allowing it to project cleaner air to every corner of the room. By expanding the degree of oscillation to 350⁰ degrees and using Air Multiplier™ technology, the machine can project at least 77 gallons of purified air per second to every corner of the room.
To avoid a cooling effect in winter, the Dyson Pure Cool™ purifying fan features a unique new backward airflow mode. Along with the forward airflow mode, which cools you as a fan with purified air, there is now a diffused airflow or purification-only mode, which can be used when you want to purify the air but don't want cool air blowing on you.
Dyson Link app: Available for iOS and Android, the Dyson Link app enables you to track indoor and outdoor pollution, temperature and humidity levels. You can also use it to control your machine and see how many hours of filter life you have left.
The new machines come with full Over the Air Update Capability (OTA) – meaning Dyson owners can continue to get the most advanced Dyson software even after purchasing the machine.
Engineered for real homes: Dyson purifying fans are designed to work in real homes. Some manufacturers of conventional air purifiers gauge their performance using a laboratory test method called "Clean Air Delivery Rate." It is conducted in a compact chamber just 127 ft.2 in size, with an added fan to circulate the air – and only one sensor to measure air quality. It is not representative of the average living room environment.
Dyson engineers created a lab test called the POLAR test. It is based on an average room size, with no added fan. Eight sensors in the corners of the room and one sensor in the center collect air quality data every 5 seconds, detecting particles of indoor air pollution that are 300 times narrower than a human hair. Analyzing the data across all nine sensors lets Dyson engineers ensure the Dyson Pure Cool™ purifying fans deliver a uniform cleaning performance throughout the whole room2.
Availability: The Dyson Pure Cool Tower (TP04) is sold for $549.99; the shorter Pure Cool (DP04) model is sold for $449.99. The replacement filters will be sold as a bundle for $79.99 and are compatible for both models (tower TP04 and shorter DP04 model).

The Reasons Why You Should Own a Radar Detector
It is when you will look into the market that you can find different devices that you can use to be safer on the road. One of these devices is the radar detector. It is in this article that we will be talking about the many different benefits that one can get when using a radar detector.
The first advantage that you will get is that you will be saved from being singled out for a speeding ticket. There are many drivers that drive at speeds that they think that is safe. All of these are done regardless of the speed limits that have been set. Different speed limits are being set with the different roads and that is what you need to know. It is speed traps when you will be taking a look at this one. With the help of a radar detector that you will be able to detect these things.
When this a radar detector that you will choose to use that it can also help you speed less. It is the speed that you are doing that can be monitored by you once you will b able to use a radar detector. It is also you that will be able to be aware of the different violation that you will have that you determine once you will use a radar detector.
It is you that will be more alert whenever you will be using a radar detector. It is the driving habits that you have that you can be aware with the help of a radar detector. It is when you are able to do this one that you will be able to be safer in the raid.
It is also with the help of a radar detector that you will be able to avoid dangerous roads and traffic congestion. It is common for most enforcers to be operating in areas where accidents are mostly will happen. This means that it can give you an advance warning of the road that might be ahead. Its means that you will have a safer ride on the road.
The accidents that have happened on the road is a thing that you will also know when you are able to have a radar detector. Whenever there are accidents that happened on the road that it is the enforcers that will be turning their radars on. Whenevr you are able to use a radar detector that it will serve as an advanced warning to many drivers. Slowing down can be done by you once you will get its alarm.
It is also with the help of a radar detector that it is the one that can have an SWS or a safety warning system. It is with its one that you’ll b able to get an alarm once an emergency car is approaching or a train for that matter.
