Edge detection is a necessary tool in image processing, machine vision and computer vision and plays a vital role in the field of feature detection and feature extraction. Edge detection has various applications in image processing such as image automation, remote sensing, criminology, security, medicines, military applications etc. Edge detection has a major role in pharmaceutical industries. In Pharmaceutical industries, drugs i.e. Tablets and Capsules are produced in a large scale every day. These tablets and capsules may not be produced precisely i.e. .they are in damaged form when produced. It could also happen that drugs are missing in a blister. So, Proper inspections of these pharmaceutical drugs are required. So edge detection helps in inspection .This paper presents comparative analysis of various edge detection techniques.

Wowhoo Wireless Phone Charger: the uniqueness and the features
Major wireless phone carriers have all been adapting the Qi wireless technology. Additionally many car manufactures are adding them to their 2014-2015 models. Manufactures include but are not limited to the following: Jeep, Toyota, Prius Harrier, Mercedes Benz, BMW, Volkswagen, Audi aswell as Porsche.
Due to the new and improved design and usability our initial launch date has been revised from Jan 7th to March 1st. we added approximately 8mm to our diameter to allow a better internal design. The small revision to the Wowhoo charger allow us to get that quicker charge which is most important. The 10% is a big jump in charging speed.
More than half of all personal aircraft accidents occur during takeoffs or landings. That’s why inventor and entrepreneur JoeBen Bevirt—known for designing airplane-like wind energy turbines—is intent on making runways obsolete. Bevirt, 40, has mobilized his wind energy team to create a personal electric airplane called S2 that takes off vertically, like a helicopter, and flies aerodynamically, like an airplane.

No full-scale prototype exists yet, but Bevirt and his team have built about two dozen 10-pound models to demonstrate their concept works. NASA has taken notice and is now funding the development of a 55-pound unmanned aerial vehicle. Supercomputer simulations of a full-scale, 1,700-pound S2 suggest it could fly two people about 200 miles (New York City to Boston) in an hour on 50 kilowatt-hours of electricity, or roughly equivalent to 1.5 gallons of fuel used by a typical two-seat airplane—which would make the new aircraft about five times more efficient.
Retractable arms reposition the motors to transition between vertical takeoff, forward flight, and landing.

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.
