The name, term, design, symbol, or any other feature that identifies one seller's product distinct from those of other sellers.you will get answers for all your questions and queries about selection, naming and positioning of a brand by reading this book.

Oscillators are integral part of many electronic systems. An oscillator is an electronic device used for the purpose of generating a signal. Almost all digital circuits are dependable on at least one clock source, which generates a rail-to-rail square wave. Applications range from clock generation in microprocessors to carrier synthesis in cellular telephones, requiring vastly different oscillator¿s topologies and performance parameters. Robust, high performance oscillator design in CMOS technology continues to pose interesting challenges. This work deals with the analysis and design of CMOS oscillators more specifically voltage controlled oscillators (VCOs). One of the most critical components in modern communication devices is the VCO. Wireless and mobile communications are two of the fastest growing microelectronics applications, and have an enormous impact on our daily lives. Driven by the insatiable commercial demand for lower cost and higher bandwidth and functionality RF transceivers, wireless communication systems are moving towards higher integration, while operating at higher frequencies

Wireless ad hoc networks has attracted extensive research interest for past 30 years. To meet the increasing demand of multimedia it is necessary to provide the quality of service in such networks. The QoS supporting components at upper layer such as signaling and routing assumes the existence of MAC protocol which solves the problem of medium contention, supports reliable communication and provides resource reservations, particularly bandwidth. The channel in wireless network is shared among the stations and one of the key challenges is estimating the usable bandwidth. It is equally important to evaluate the performance of MAC protocols proposed in literature. This books is a effort made to summarize the efforts of researchers who contributed towards the development of various aspects for estimating the available bandwidth in network.

The purpose of the project is to develop a Smart Home system based empowered by networking technology, single board computer Raspberry Pi and Android Phone, laptop etc. The proposed Smart Home system is restricted do image transmission for home surveillance. Image from camera is collected by the dropbox server is send wirelessly. The Raspberry Pi will transmit data using WLAN. Home automation provides the automatic control of home appliances also monitor home to provide safety from intruder. Raspberry Pi is used as main part of project. This will enable smartphone access the RPi trough web browser application. Remote communication from user is carried out through cloud storage server. The cloud storage (Dropbox) has been synchronizing with the data base in Raspberry Pi. The image transfer successfully done for home surveillance application. The project can be further extended for include more application including power control and monitoring, emergency alert and health monitoring.

The conventional power plants of 1950s were equipped with continuously acting automatic voltage regulators to improve the transient stability of system. The high gain of these voltage regulators has a destabilizing effect on power system. The power oscillations of small magnitude and high frequency, which often persisted in power system, present the limitation to the amount of power transmitted within the system. Improved performance has been achieved by adding damping to the system by employing power system stabilizers (PSS). Conventionally a lead- lag PSS was used to achieve this objective but has certain demerits like sluggish response etc. The use of Artificial intelligence has gain momentum now days in power system. This book gives the overview of various artificial intelligence techniques used in PSS till now and a case study based on fuzzy logic based PSS, its performance for a grid connected synchronous generator, and finally the effect of type of membership functions on PSS. This is my second book in this area. Its a perfect book for the students, researchers and industry related experts to explore the possibility of AI techniques in power system stability problems.

This book is a short introduction to power system planning and operation using advanced geometrical methods. This work addresses applied mathematicians, theoretical physicists and power engineers interested in novel mathematical approaches to power network theory.
