Abstract: Now a days switched reluctance motor (SRM) becomes more popular among the various electric drives available in the domestic and industrial application due to its simple and robust construction. The application of the machine, the operation of the switched reluctance motor can be categorized into the low and medium speed operation and high speed … Read more
Abstract: The statistics of ‘Times of India’ (25 July’2014) states that 66% of accident fatalities occurred at unmanned level crossing in INDIA. The road and rail accidents are increasing because of human errors. Majority of the level crossing positions are not guided by any accident preventive mechanism and even not accompanied by a skilled person. … Read more
ABSTRACT: This paper describes the design of a simple low cost microcontroller based real time monitoring and control of multisensor using gsm techniques in embedded system. GSM modem using AT comments for sending and receiving message. The LM35 is an integrated circuit sensor that can be used to measure temperature with electrical output proportional to … Read more
Chapter 1: INTRODUCTION Steel can be classified in to two main groups that is hot-rolled shaped and cold-formed steel sheet. The usage of cold-formed steel channel in building construction began in1980’s, where United State and Great Britain are the first country that is using this technology. It can be used as individual structure framing member … Read more
CHAPTER I INTRODUCTION Modern technology influenced the people’s lifestyle. This made engineers and inventors innovate or improve a device. Portable gadgets gain attention for its increasing demand, and it has been quite a challenge especially in the battery industry. A typical mobile device uses wall sockets for charging before it can be used and carried. … Read more
A hydraulic machine is a device in which mechanical energy is transferred from the liquid flowing through the machine to its operating member (runner, piston and others) or from the operating member of the machine to the liquid flowing through it. Hydraulic machines in which receives energy from the flowing liquid it and energy of … Read more
Abstract In this thesis, the microprocessor with dc voltmeter checking the voltage applied to the two separate entrance with based on the principle of. I plan to use the IC as a pic16f877a microcontroller. In summary, if I open the circuit when the voltage applied to the principle of two separate working voltage depending on … Read more
INTRODUCTION A remote sensing system is collection of hubs arranged into a system. A remote sensing framework is a collection of center points created into a pleasing framework. Each center point embodies planning limit (one or more microcontrollers, CPUs or DSP chips), may contain distinctive sorts of memory (program, data and burst memories), have a … Read more
Page 1 1. INTRODUCTION In machine tool applications like centre lathes, milling machines , CNC turning lathes , Vertical machining centres , vertical turret lathes, etc. it is often required to lift heavy work-pieces using conventional winches or chain blocks which may require assistance from two or more workers for loading the work-piece on the … Read more
Current-Mode Control (CMC) has been a popular and effective control technique for power converter systems for many years. Traditional CMC systems employ pure analog components. With the development of computer technology, digital implementation of CMC systems is becoming a practical approach. In many power converter systems, the output voltage of the power stage is sensed … Read more

Vibration monitoring is the most widely and cost-effective monitoring technique. It is to detect, locate and distinguish faults [1]. Vibration signal didn’t benefit before analysis, because the signal was random and complex. Also different parts of rotating machine are generated various signals components. Analyzing different features extracted from these signal components generated by several of … Read more
Abstract: In the process of channel estimation coding, channel estimation adaptive filters are more commonly used. In the process of adaptive filtration the selection of band processing is an important criterion. For the selected band the signals are estimated using mean square deviation (MSD). With the approach of channel estimation filtration normalized channel estimation adaptive … Read more
One challenge in designing phase-locked loops (PLLs) for application-specific integrated circuits (ASICs) is providing ample flexibility for a wide variety of applications, including processors and video/chip interfaces. PLLs commonly are used to take low-frequency off-chip clocks, typically from crystals, and generate high-frequency on-chip clocks. The diversity of ASIC applications has also led to diversity in … Read more
Peak to Average Power Ratio (PAPR) is one of the most important drawback faced by Multi Carrier Code Division Multiple Access (MC CDMA). In this paper a new technique is introduced to reduce the PAPR, it is based on combining Discrete Hartley Transform and Mu-law Companding. The performance of PAPR is calculated using the Complementary … Read more
