Voltage instability is a system stressed phenomena during which distance relay reach issues arises. Zone-3 unit of distance relay is highly affected by such phenomena. Protective relay unable to discriminate the fault situation from voltage unstable condition and issues a trip signal. As, three phase fault and voltage instability are balanced phenomena, zone-3 unit is unable to make a clear discrimination...
This paper proposes an area efficient and low power Reed-Solomon (RS) decoder. The proposed decoder is designed using eight stage arithmetic pipelined architecture. The pipelined architecture of RS decoder performs the detection of error locator from the input stream and computes the error magnitude polynomial using the Berleykamp Massey's algorithm. The evaluation of error locator and computation...
Every nation dreams for highly efficient and economical type of energy production units. The scenario of power sector is inversely proportional as far as the generation and demand of power is concern. In India, normally the power plants run on the availability of fuel and consumers. Majority of the power generation units are fuel based in Indian power sector. There are so many types of fuel but coal...
Active ECUs (Electronic Control Unit) in a hybrid car while it is charging leads to inefficient power usage and reduction in ECU lifetime. To solve this issue, AUTOSAR has suggested PN (partial networking). As per the AUTOSAR specification, ECUs which are not required to be kept active during battery charging must be shutdown. This project's aim is to analyze the robustness of the design suggested...
Data gathering by leveraging Sink's mobility in large-scale Wireless Sensor Networks (wsns) has drawn substantial interest in recent years. Challenge is to collect data in wsns through optimized network performance. Current researchers focus on how to minimize the energy of sensor nodes to help improve the lifetime of the node. Identifying mobile sink's moving trajectory in advance is cumbersome process...
With increasing use of power electronics, the amount of harmonics and other power quality problems are increasing in the system. Because of this power quality has been an important topic in the area of research. There are a number of reliability and economic issues with respect to electronic equipment. In such a scenario it is important to study the causes, effects and mitigation technologies for...
Due to the increase in number of vehicles traffic congestion problem has increased dramatically. This gave rise to systems like Driver Assistance Systems (DAS) that helps the driver to drive vehicle safely by sensing nearby vehicles and obstacles. It also increases road safety. Such systems also reduce the fatigue level of the driver as an added benefit. Then came in the Advance Driver Assistance...
This paper presents the analysis of feedback linearization based optimal controller design for ElectroMagnetic Levitation (EML) system, which is a class of nonlinear and unstable system. Using feedback linearization method, nonlinear model is first converted into controllable linearized model in large operating range under certain conditions. Using linearized model, optimal controller is designed...
Flush Air Data Sensing System (FADS) form a mission critical sub system in future aerospace vehicle. FADS makes use of surface pressure measurements from the nose cap of the vehicle for deriving the air data parameters of the vehicle such as angle of attack, angle of sideslip, Mach number, etc. These parameters find use in the flight control and guidance systems, and also assist in the overall mission...
The susceptibility to Single Event Upset (SEU) is very high for Configuration memory of SRAM based Field Programmable Gate Arrays (FPGA) compared to other FPGA resources. The reduction in feature sizes and core voltages leads to a reduction in the critical charge required to change the state of a memory cell. The SEUs cause failures in the system functionality implemented in FPGA. Fault tolerant techniques...
For the past five decades, de-speckling of Synthetic Aperture Radar (SAR) images is one of the hottest research areas. This research work presents the comprehensive survey about the various de-speckling methods. After studying this survey, the researcher comes to know the various de-speckling techniques also with merits and demerits of each method and the different parameters used to evaluate the...
A worm is a standalone program, which is self-replicating malware that distributes itself to other computers and networks. An Internet worm can spread across the network and infect millions of computers in very little time. Damages caused by such attacks are considered very high. Worms affect the network packet and its performance. In this paper, different methods are analyzed to detect Internet worms...
