Results of Intel ISEF 2017

The end of last week was marked by another prize in the treasury of Ukrainian young scientists. Tischenko Valeria Viktorovna - one of the finalists of the national qualifying stage, won the fourth place at the international competition Intel ISEF.

Tough struggle of several thousand young scientists and the opportunity to get prizes only the best of the best. And it is extremely pleasant to realize that one of them was our compatriot.

Her project "Production of electricity by waves on the surface of water" refers to the energy sector and allows to receive electricity using the principles of electromagnetic induction.

A few words should also be said about the youngest scientist, because she, like many Ukrainian schoolchildren, had no special conditions, except perhaps her own talent, enthusiasm, dedication and competent mentors. Nevertheless, a pupil of the Kherson Physical and Technical Lyceum of the Kherson City Council at the Kherson National Technical University and Dnepropetrovsk National University was able to demonstrate a high level of knowledge and a development class, which is confirmed by the award.

This fall will be the next national selection contest Intel Techno Ukraine, and early next year - Intel Eco Ukraine. Winners of these competitions will also have the opportunity to present their developments at the international competition Intel ISEF, which will be held next spring. So if you want to leave your mark in science and get an opportunity to develop your own talent - hurry up to prepare your project, and maybe your will win the prize next year.

Root for our team

Less time is left before the final and closing the Intel ISEF 2017. This week, our team managed to relax and have a good work. Participants visited the most prominent tourist attractions of Los Angeles, and spend every effort to prepare their stands for contest, interacting with judges and other contestants. Today they are still waiting for a busy open day, when number of the visitors will drasicly increase - scientists, businessmen and just interested people will visit competition. Sometimes that day interesting projects find their investors, and get a quick start.

But in fact the biggest thrill of all participants connected with May 19, the day of announcement of the winners and the closing of the contest. That's when they find out how the judges rated their studies and whether their efforts have achieved the goal.

At this time, we can only wish our students inspiration, success and victory!

Join our Facebook page and root for our team. And we, in turn, will provide you with current information about the finalists and projects that won prizes.

Go for victory

This day will be remembered not only for warmth and the next stage of Eurovision, but the positive attitude of our schoolchilds who went to the US to gain awards in the international competition of scientific and technical creativity Intel ISEF. Last hours before the flight to California, they spent with their mentors and representatives of local TV channels. So, telling reporters about their inventions, they can immediately test the efficiency and soundness of tips for project presentations. After interview, and gathering all necessary, they went in Boryspil airport, where they went in long transatlantic trip to the United States.

Intel ISEF will be held from 14 to 19 May in Los Angeles, California. Participants expect cultural and entertainment program with a visit to the most famous tourist attractions of the state. But the main thing for them is not fun, but defense of the projects at competition. Winners will receive not only certificates and global fame, but also monetary support - including three million dollars of prize money.

This year Ukraine will be represented by six members with five projects (one of them are team project). These include robotics, mathematics, energy, ecology and chemistry cathegories. Most of the projects illustrated not only with posters, but the current models that demonstrate the principles inherent in the invention. So our contestants stand fully prepared - well equipped and ready for discussion with the judges. We can only wish them patience and luck - let their projects will be among the best.

Asteroid clay makes great radiation shield

The huge rocks that hurtle through space may prove to be lifesavers for astronauts. Clays extracted from asteroids could be used on deep space missions to shield against celestial radiation.

Radiation from cosmic rays is one of the biggest health risks astronauts will face on long space missions, such as a proposed trip to Mars or settlement on the moon. A 2013 study suggested that a return trip to Mars would expose astronauts to a lifetime’s dose in one go.

But the heavy aluminium shields currently used for short missions would be too expensive to ship. For a long-term presence on the moon or Mars, we will need to use materials found in space, says Daniel Britt at the University of Central Florida.

“Eventually everything should be able to be produced off Earth if any serious size outpost, base or colony is to be considered,” says Paul van Susante at Michigan Technological University.

Asteroids could provide the answer, says Britt. Clays in asteroids are rich in hydrogen, which is the most effective shielding material for protons and cosmic rays. Britt and his colleague Leos Pohl found that the clays are up to 10 per cent more effective than aluminium – which is used in most current shields – at stopping the high-energy charged particles given off by the sun and other cosmic bodies.

Exactly how the clays could be extracted from the asteroids is still up for discussion. “No current machines exist for actual mining in zero gravity,” says van Susante.

But there are a few ways it could be done. For example, the clays are non-magnetic, so they could be separated from other materials in an asteroid using massive magnets.

“Doing anything in space is not trivial, but there are several paths forward,” Britt says.

Quantum Learning

The efficient characterization of quantum systems, the verification of the operations of quantum devices and the validation of underpinning physical models are central challenges for quantum technologies and fundamental physics. The computational cost of such studies could be improved by machine learning enhanced by quantum simulators. Here researchers interface two different quantum systems through a classical channel—a silicon-photonics quantum simulator and an electron spin in a diamond nitrogen–vacancy centre—and use the former to learn the Hamiltonian of the latter via Bayesian inference. Researchers learn the salient Hamiltonian parameter with an uncertainty of approximately. Furthermore, an observed saturation in the learning algorithm suggests deficiencies in the underlying Hamiltonian model, which we exploit to further improve the model. They implement an interactive version of the protocol and experimentally show its ability to characterize the operation of the quantum photonic device.

Under newly proposed California self-driving car rules, the state’s Department of Motor Vehicles will let companies test autonomous vehicles that lack the steering wheel. Three years ago Google's self driving car project (now Waymo) introduced a self driving car with no steering wheel.

Once the cars have been tested either on a closed track or through computer modeling, self-driving cars will be able to tool around California roads without drivers or even the ability to be driven by a driver.

Prior to this, autonomous vehicles had to have a driver sitting ready to take charge at any second should anything go wrong.

Instead, manufacturers will now have to submit an application, certify there's a communication link to the vehicle, provide a copy of their plans for any interactions with local law enforcement, create a training program for remote operators and get a safety assessment letter from the National Highway Traffic Safety Administration.

In a shift, companies will no longer have to get permission from the jurisdiction where they plan to test the cars but instead simply notify them in writing.

The proposed regulations were published Friday and the public now has until April 24 to comment on them. The new rules could take effect in 2018.

Boston Dynamics has a new robot called Handle. It is a research robot that stands 6.5 ft tall, travels at 9 mph and jumps 4 feet vertically. It uses electric power to operate both electric and hydraulic actuators, with a range of about 15 miles on one battery charge. Handle uses many of the same dynamics, balance and mobile manipulation principles found in the quadruped and biped robots we build, but with only about 10 actuated joints, it is significantly less complex. Wheels are efficient on flat surfaces while legs can go almost anywhere: by combining wheels and legs Handle can have the best of both worlds.

It can lift 100 pounds.

Boston Dynamics builds advanced robots with remarkable behavior: mobility, agility, dexterity and speed. We use sensor-based controls and computation to unlock the capabilities of complex mechanisms. Our world-class development teams take projects from initial concept to proof-of-principle prototyping to build-test-build engineering, to field testing and low-rate production.

BYU mechanical engineers have created an origami-inspired, lightweight bulletproof shield that can protect law enforcement from gunfire. The new ballistic barrier can be folded compactly when not in use, making it easier to transport and deploy. When expanded — which takes only five seconds — it can provide cover for officers and stop bullets from several types of handguns.

“We worked with a federal special agent to understand what their needs were, as well as SWAT teams, police officers and law enforcement, and found that the current solutions are often too heavy and not as portable as they would like,” said Larry Howell, professor of mechanical engineering at BYU. “We wanted to create something that was compact, portable, lightweight and worked really well to protect them.”

In working with law enforcement, BYU researchers learned much of what is currently used hasn’t evolved much from medieval times: shields that are mostly flat, awkward plates that cover only one person. Current barriers are so heavy and cumbersome they make it difficult for officers to move into position.

The barrier Howell and his colleagues designed is made of 12 layers of bulletproof Kevlar and weighs only 55 pounds (many of the steel-based barriers in current use approach 100 pounds). The BYU-built barrier uses a Yoshimura origami crease pattern to expand around an officer, providing protection on the side in addition to protecting them in the front.

In testing, the barrier successfully stopped bullets from 9 mm, .357 Magnum and .44 Magnum pistols.

“Those are significant handguns with power,” Howell said. “We suspected that something as large as a .44 Magnum would actually tip it over, but that didn’t happen. The barrier is very stable, even with large bullets hitting it.”

The researchers constructed the barrier prototypes to be extremely stiff and protective throughout, while also maintaining the flexible qualities of Kevlar fabric so they can be folded compactly. Since Kevlar fabric is subject to fraying, abrasion and is sensitive to sunlight and water, the team also made a concentrated effort to reinforce it against the environment.

“It goes from a very compact state that you can carry around in the trunk of a car to something you can take with you, open up and take cover behind to be safe from bullets,” said Terri Bateman, BYU adjunct professor of engineering and research team member. “Then you can easily fold it up and move it if you need to advance your position.”

In addition to protecting police officers, researchers believe the barrier could be used to protect children in a school or a wounded person in an emergency situation. Although the ballistic barrier is now just in prototype form and not currently in use by any law enforcement agencies, Howell and Bateman have tested it with officers on site. The response has been positive so far.

“There are a lot of risks to law personnel and we feel like this particular product can really make a difference and save a lot of lives,” Bateman said. “It makes us feel like we’re really making a difference in the world.”
