Abstract:
Neural networks and deep learning currently provide the best solutions to many problems in image recognition, speech recognition, and natural language processing. In this Paper we propose a simple technique train the neural network for speech modulation. The data sets used in the training have used the technique of Mel frequency cepstral coefficient (MFCC) to extract features from speech and map the differences in them between different speakers to generate a modulation vector. We aim that the host voice when modulated into target voice use this network to learn these modulation from large-scale unlabeled data. The network would modulate the speech without the modulation vector after a certain amount of time students.

Medicine: Touch sensitive bionic arm | IJSRD

Researchers at the Cleveland Veterans Affairs Medical Center and Case Western Reserve University have developed a new kind of interface that can convey a sense of touch from 20 spots on a prosthetic hand. It does this by directly stimulating nerve bundles—known as peripheral nerves—in the arms of patients; two people have so far been fitted with the interface. What’s more, the implants continue to work after 18 months, a noteworthy milestone given that electrical interfaces to nerve tissue can gradually degrade in performance.

Fusion Reactor Concept Could Be Cheaper Than Coal

University of Washington
Summary:
Engineers have designed a concept for a fusion reactor that, when scaled up to the size of a large electrical power plant, would rival costs for a new coal-fired plant with similar electrical output.

Research . .  ? ?  Lets Do IT… #IJSRD

Fusion energy almost sounds too good to be true — zero greenhouse gas emissions, no long-lived radioactive waste, a nearly unlimited fuel supply.

Perhaps the biggest roadblock to adopting fusion energy is that the economics haven’t penciled out. Fusion power designs aren’t cheap enough to outperform systems that use fossil fuels such as coal and natural gas.

IJSRD is a leading e-journal, under which we are encouraging and exploring newer ideas of current trends in Engineering and Science by publishing papers containing pure knowledge.

University of Washington engineers hope to change that. They have designed a concept for a fusion reactor that, when scaled up to the size of a large electrical power plant, would rival costs for a new coal-fired plant with similar electrical output.

The team published its reactor design and cost-analysis findings last spring and will present results Oct. 17 at the International Atomic Energy Agency’s Fusion Energy Conference in St. Petersburg, Russia.

“Right now, this design has the greatest potential of producing economical fusion power of any current concept,” said Thomas Jarboe, a UW professor of aeronautics and astronautics and an adjunct professor in physics.

The UW’s reactor, called the dynomak, started as a class project taught by Jarboe two years ago. After the class ended, Jarboe and doctoral student Derek Sutherland — who previously worked on a reactor design at the Massachusetts Institute of Technology — continued to develop and refine the concept.

The design builds on existing technology and creates a magnetic field within a closed space to hold plasma in place long enough for fusion to occur, allowing the hot plasma to react and burn. The reactor itself would be largely self-sustaining, meaning it would continuously heat the plasma to maintain thermonuclear conditions. Heat generated from the reactor would heat up a coolant that is used to spin a turbine and generate electricity, similar to how a typical power reactor works.

“This is a much more elegant solution because the medium in which you generate fusion is the medium in which you’re also driving all the current required to confine it,” Sutherland said.

There are several ways to create a magnetic field, which is crucial to keeping a fusion reactor going. The UW’s design is known as a spheromak, meaning it generates the majority of magnetic fields by driving electrical currents into the plasma itself. This reduces the amount of required materials and actually allows researchers to shrink the overall size of the reactor.

Other designs, such as the experimental fusion reactor project that’s currently being built in France — called Iter — have to be much larger than the UW’s because they rely on superconducting coils that circle around the outside of the device to provide a similar magnetic field. When compared with the fusion reactor concept in France, the UW’s is much less expensive — roughly one-tenth the cost of Iter — while producing five times the amount of energy.

The UW researchers factored the cost of building a fusion reactor power plant using their design and compared that with building a coal power plant. They used a metric called “overnight capital costs,” which includes all costs, particularly startup infrastructure fees. A fusion power plant producing 1 gigawatt (1 billion watts) of power would cost $2.7 billion, while a coal plant of the same output would cost $2.8 billion, according to their analysis.

“If we do invest in this type of fusion, we could be rewarded because the commercial reactor unit already looks economical,” Sutherland said. “It’s very exciting.”

Right now, the UW’s concept is about one-tenth the size and power output of a final product, which is still years away. The researchers have successfully tested the prototype’s ability to sustain a plasma efficiently, and as they further develop and expand the size of the device they can ramp up to higher-temperature plasma and get significant fusion power output.

The team has filed patents on the reactor concept with the UW’s Center for Commercialization and plans to continue developing and scaling up its prototypes.

Other members of the UW design team include Kyle Morgan of physics; Eric Lavine, Michal Hughes, George Marklin, Chris Hansen, Brian Victor, Michael Pfaff, and Aaron Hossack of aeronautics and astronautics; Brian Nelson of electrical engineering; and, Yu Kamikawa and Phillip Andrist formerly of the UW.

The research was funded by the U.S. Department of Energy.

Carbon Nanotube ‘Shock Absorbers’ Excel At Dampening Vibration – #IJSRD

Rensselaer Polytechnic Institute
Summary:
Research on a new class of nanostructured materials used to reduce vibrations in mechanical equipment and electronic devices, being developed by a team of scientists at Rensselaer Polytechnic Institute, will be featured in Nature Materials.
blogResearch Lets DO IT…. #IJSRD

Research on a new class of nanostructured materials used to reduce vibrations in mechanical equipment and electronic devices, being developed by a team of scientists at Rensselaer Polytechnic Institute, will be featured in Nature Materials.

“The nanoscale building blocks we have developed have both micro and macro applications,” said Nikhil Koratkar, assistant professor of mechanical, aerospace, and nuclear engineering at Rensselaer. “The new systems reduce and control vibrations within structures and will benefit the performance, safety, and reliability of future manufacturing equipment, sensitive laboratory equipment, and everyday electronic devices.”

The Rensselaer research team, led by Koratkar, added carbon nanotube fillers to traditional vibration reduction materials to enhance their energy dissipation capability. Adding large quantities of nanoscale fillers increases the amount of surface area, and thereby increases frictional sliding that occurs at the filler-to-filler interface. The result is a decrease in vibrations.

In 2004, Koratkar received a National Science Foundation (NSF) Faculty Early Career Development Award (CAREER) to fund the development of these new materials. Additional Rensselaer researchers on the project include Pulickel Ajayan, professor of materials science and engineering; Pawel Keblinksi, associate professor of materials science and engineering; and Jonghwan Suhr, a doctoral student in mechanical, aerospace, and nuclear engineering.

The research is available in the Nature Materials journal online, and will be published in an upcoming print edition of the journal.
