Convolutional Networks for Fast, Energy-Efficient Neuromorphic Computing

Deep networks are now able to achieve human-level performance on a broad spectrum of recognition tasks. Independently, neuromorphic computing has now demonstrated unprecedented energy-efficiency through a new chip architecture based on spiking neurons, low precision synapses, and a scalable communication network. Here, we demonstrate that neuromorphic computing, despite its novel architectural primitives, can implement deep convolution networks that i) approach state-of-the-art classification accuracy across 8 standard datasets, encompassing vision and speech, ii) perform inference while preserving the hardware's underlying energy-efficiency and high throughput, running on the aforementioned datasets at between 1200 and 2600 frames per second and using between 25 and 275 mW (effectively > 6000 frames / sec / W) and iii) can be specified and trained using backpropagation with the same ease-of-use as contemporary deep learning. For the first time, the algorithmic power of deep learning can be merged with the efficiency of neuromorphic processors, bringing the promise of embedded, intelligent, brain-inspired computing one step closer.Comment: 7 pages, 6 figure

Comparison of Sine and Space Vector Modulated Embedded Z-source Inverter fed Three Phase Induction Motor Drive System

This paper deals with performance of photovoltaic powered Embedded Z-Source Inverter (EZSI) fed Induction motor drive. The DC output from the PV-Panel is boosted and converted into AC using Embedded Z-Source Inverter. EZSI system based on the concept of Z-Source Inverter (ZSI), which provides single stage power conversion. The EZSI also produce same voltage gain as that of the ZSI based system. In EZSI the DC source is embedded within the X-shaped LC impedance network, due to this EZSI has the added advantage of inherent source filtering capability , this can be achieved without any extra passive filter. EZSI can produce the AC output voltage which is greater than the DC link voltage. EZSI system also provides ride-through capability under voltage sags. In this paper the performance of space vector modulated EZSI fed Induction Motor Drive is compared with sinusoidal PWM controlled EZSI fed Drive system. The PV powered EZSI fed three phase Induction Motor System is designed, modeled and simulated using MAT LAB-SIMULINK and the corresponding results are presented. This drive system has advantages like voltage boosting ability and reduced harmonic content

Intelligent Car

Abstract INTELLIGENT CAR (ICAR) is a car, developed on eye-tracking software using a camera. The ICAR the first Intelligent car that works with eye control and automatic driving. You can ride a car and move around where ever you want. The car drives Right, left, forward and stop using your eyes with the help of camera and coding. You need to sit facing the camera to control it. The main advantage is the car drives without any hassle in the roadways because of sensors i.e without any accidents/hitting any objects. It requires some hardware along with software along with a camera. Roads are easy and cost-effective for travelling through vehicles and walking people. Physically challenged people can also travel easily by I-Car, they need not call any person for help on the roads or depend on anyone to move from one place to another.</jats:p

Induction of defense-mechanisms in mungbean suspension cultured cells by an elicitor from macrophomina phaseolina

An elicitor molecule has been separated from Macrophomina phaseolina, the root rot pathogen of mungbean (Vigna radiata). Cell cultures of mung­bean cultivars one resistant and another susceptible to the pathogen, which responded to the elicitor have been established. The elicitor treatment induced rapid increases in phenolic synthesis, activation of phenylalanine ammonia-lyase and peroxidase in the cultured cells. Relative increases in phenolic synthesis and peroxidase activity were observed in suspension-cultured cells of the resistant cultivar compared to that of the susceptible one due to elicitor treatment
