Abstract

This paper is mainly focused to design modern semiconductor memory. Now-a-days, the conventional memory design should be implemented in CAD tools. While, the size of the memories that can be generated are still limited to some degree. The proposed memory system will use automatic synthesis approach. The bit density reduction and minimum chip area will be achieved by Reconfigurable CMOL memory array (bad bit omission), combined with error correction code techniques, in Reconfigurable terabyte-scale, hybrid Nano-Device /semiconductor memories, as a function of the nano-device fabrication yield and the micro-to-nano scale ratio. The results prove that by using the best (but hardly practicable) reconfiguration and block size optimization, CMOL memories with a pitch ratio of 10 should overcome purely semiconductor memories in useful bit density if the fraction of spoiled nano-devices is beneath ~15%, while in order to get an order-of-magnitude , the advantage in density, and the number of bad devices have to be below ~2%. For the simple 'Repair Most' technique of bad bit omission, complemented with the Hamming-code error correction. When applied to CMOL memories, the automatic synthesis technique reduces the chip area 'swelling' to just 40% at as many as 0.1% of bad devices. In addition, power and speed of the CMOL memories are estimated. The proposed system determines that Nano-devices are well suited in modern memory system.

Abstract

Image Denoising is a method of removal or reduction of noises, that are incurred during the image capturing, image acquisition, and transmission due to the electronic and photometric sources. This paper is mainly focused to design an efficient architecture for removal of random-valued impulse noise from corrupted images. To achieve this, a good image denoising method property is that, it will remove noise while preserving edges is proposed. The proposed methodology is Decision-Tree-Based Denoising Method (DTBDM), which consists of decision tree based impulse detector, to detect the noisy pixel and to locate the edges by an edge preserving filter to reconstruct the intensity values of noisy pixels. Further, it is enhanced by using modified square root Carry Select Adder (SQRT CSA), in order to improve the execution time. Here, the serial adder is replaced with modified square root CSA to reduce computational time and area. So this technique can be used for many real time applications like medical imaging, scanning techniques, face recognition, etc.

Abstract

In this paper the design of roadway powered online electric vehicles by using wireless power transfer system is presented. Electric vehicles are charged on the roadway during their motion by the Wireless Power Transfer technology. Wireless Power Transfer (WPT) is the process of transferring power from transmission part into receiver part without passing through any man-made conductive elements interconnecting them. Online electric vehicles works on the principle of ElectroMagnetic Induction (EMI). Electromagnetic Inductive Power Transfer (IPT) is a popular technique of transferring power wirelessly over a short range. The result to be expected in this system is 80% of power transfer efficiency below 26 cm air gap.

Abstract

Indian traffic is non-lane based and chaotic. In recent years, wireless networks are widely used in the road transportation. The proposed system tracks the location of an emergency vehicle, and provides a green wave to the vehicle. Implementation is adopted using RFID transponders, tags, readers, and wireless technologies. RFID is a profitable system which will provide uninterrupted wireless communication in the network even in all conditions. RFID technology allows several items to be quickly scanned, enabling fast identification of a particular ambulance in the lane and also the stolen vehicles, even when it is surrounded by several other items and proximity sensors to calculate the count of normal vehicles was not attempted in traffic control. RFID access control system controls the entire operation by using RFID readers and RFID tags and processes them into the wireless network by using GSM technology, the type of modem to access the speed of operation without delay by using ZigBee, operating at low-power to perform predefined tasks at all the levels of work configurations. Therefore the proposed system provides a simple, low-cost, and real time smart traffic light control system that aims to overcome many defects and improve the traffic management.

Abstract

Over the years, the researchers have made inroads in the ways in which air pollution monitoring and its assessment has been carried out. The authors have reviewed and analyzed the different schemes or methodologies which have been proposed by different researchers concerned with air pollution monitoring and assessment with a goal of creating a customized system which caters to specific target groups who are armed with relevant information on air pollution on a periodic basis and specifically in form of alarms whenever the need arises. The review has been carried keeping in mind the advantage and the disadvantage of the proposed scheme. In this review, they have tried to analyze only those schemes or methodologies where the researchers have added to subsequent improvement in the existing methodologies and are cost effective and easily implementable. The review includes research papers, publications, web sources, and other available literature with an eye towards providing a comprehensive comparative analysis. Thus they put forward the insights gained from the review.
