About the Cover

Superconductor is an element, inter-metallic alloy or compound that conduct electricity without resistance below a certain temperature. Organic superconductors are composed of an electron donor (the planar organic molecule) and an electron acceptor (a non-organic anion). Organic superconductors are part of the organic conductor family which includes: molecular salts, polymers and pure carbon systems (including carbon nanotubes and C60 compounds). Superconducting technologies will play an important role in the future smart grid, because the application of superconductor technologies in the power grid can decrease power losses, relieve overload, avoid higher levels of transmission voltage, increase power transmission capacity, and improve power quality and grid stability (Image: Anusuya V, Construction of superconductor by solvent, Discovery Engineering, 2013, 2(5), 9), (Images: www.breakthroughenergynews.com).

ANALYSIS

Real time depth computation using stereo imaging

Prashant J Bagga

Stereo imaging is one of the methods to get an estimate about depth distance of various objects in the scene from the camera. This paper presents the process involved in developing a stereo imaging module for use on a robot to plan paths and movements, and for avoiding obstacles. The module is implemented using the open source computer vision library OpenCV. This module works in real-time and can deal with dynamic scenes to a fair extent.

Integrating real with the virtual: welcome to the virtual reality

Aman Jain, Aman Wahi, Ravi Ahuja

With advancement of the technology, sitting in front of computer and playing 2D games is now a bore. Here, we come up with a very new idea – virtual reality. Virtual reality is a world, which is not present around us in the physical state, yet we experience it by using modern day technology. The modern science has allowed us to not only play the games but to experience it. Though it is not real we are still trying to make it very much similar to the real world environment so that we can interact with the real world by seeing it, hearing it, touching it, smelling it and feeling it. Though the virtual world is so fantasizing and fun to watch it should satisfy three of the following conditions: total realism, physical interaction and no boundaries. To make our virtual world more interactive we use the technology of programmable matter and claytronics. The programmable matter is the matter which consists of tiny modular robots that can change its shape accordingly and can transform from one shape to another.

Novel microchips: a step forward to construct an artificial brain

Anusuya V

Microchip is a set of interconnected electronic components such as transistors and resistors that are etched or imprinted on a tiny chip of a semiconducting material, such as silicon or germanium. Microchips are built layer by layer on a wafer of the semiconductor material silicon. The layers are built by a process called photolithography involving chemicals, gases, and light. Novel microchips imitate the brain's information processing in real time. Computer and the human brain is one that has been made for over half a century, the way each processes could not be more different. IBM researchers have designed a revolutionary chip for the first time, actually mimics the functioning of a human brain. Researchers from the University of Zurich and ETH Zurich and colleagues from the EU and US have taken a step closer to achieving the goal of constructing an artificial brain that’s just as a real brain.

Online retailing – the Indian viewpoint

Charul Thareja, Ritika Ghai, Vaibhav Jain

The intention of this paper is to provide an overview on the subject of Online Retailing with a special reference to the Indian market. The whole scenario of e-shopping in India is summed up under various headlines to give a detailed description of all the current proceedings as well as the future approximations in the online retail sector. Through this paper we are introducing the concept of online retailing with a brief mention of its origin and history along with the various advantages and disadvantages it possess. The leading online shopping stores in India have been provided in between. The paper also offers the various online retailing statistics and a comprehensive analysis and study of the customer taste.
