This paper mainly focuses on the survey of botnet and its detection and some of the botnet characteristics and prevent IRC based botnets and also the simple measures to be taken to avoid the effect of botnet. In this survey, botnet detection techniques can be classified into four categories. Signature-based, anomaly based, DNS based, and mining-base and also discuss about the overview of characteristics. 2. Introduction: A botnet, otherwise known as “zombie army,” is a group of systems
Fourier series and harmonic elimination theory is discussed briefly to derive the transcendental equations for the fundamental frequency switching method for multilevel inverter. In the second part of this chapter a new evolutionary technique Big Bang-Big Crunch optimization is used for solving the transcendental equations for the fundamental frequency switching method for multilevel inverters. There are numerous methods which are as follows like (SPWM) First Sinusoidal Pulse Width Modulation, (MCPWM)Second
Virtual Private Network. It provides a private network across the public network (Internet). This allows the user to transmit and receive data to the private network across Internet, like it is being directly connected to it. VPN has the characteristics of point-to-point and private link. To resemble a point-to-point link, the data is sent along with the routing information necessary to reach the destination through the public network. Data is encrypted and only the users in the network can access the
Interconnection networks and protocols used for cache-coherence Sanket Desai Computer Engineering California State University Fullerton Fullerton, United States Swetang Gajjar Computer Engineering California State University Fullerton Fullerton, United States Abstract— There have been various cases where the processors sharing memory where one process reads and other writes when a processor is sharing is reading requires the memory to be used by various process but it does not create a problem
power systems operating close to security and stability limits. Environment constraints severely limit the expansion of a transmission network. In a deregulated market there is a need for a new kind of voltage and power flow control (for which existing power systems are not designed for). The transmission capacity for all transactions in the open access networks needs to be determined. Fewer operators are engaged in the supervision and operation of power systems. Although power generation, transmission

Software Based Approach: Hardware based approaches constitute only a part of the solution, they offer limited power knob options. Considering the continuously evolving hardware configurations and increasing hardware heterogeneity, data management software shall play an important role in energy optimization. Query optimization and physical data independence provide opportunities for software level control over power performance tradeoffs [7,32]. Adapting Query Optimizer Energy optimization
Mobile Communication from 1G to 4G Ajit Singh Grewal GEORGE MASON UNIVERSITY Fairfax, Virginia, USA Abstract The evolution of mobile telephone system can be classified into different generation based on the level of maturity in technology. This classification does not depend on any standardized facts. The purpose of this paper is to provide the history of mobile communication and provide an overview of 4G and its features, architecture, key technologies and challenges. Introduction: From 1G (First
Abstract — Electricity supports almost all sectors of the economy and is a critical infrastructure in a nation. The central grid-based electricity gets considered as the most convenient and reliable form of energy. However, it has not met the entire customer demand need for power since over 1.3 billion people cannot access electricity. Microgrids are one of the new technologies developed to solve this problem and support emerging economies and sustainable development. This paper describes the evolution
using Artificial Neural Network. 2.Introduction:- In high-performance spacecraft, aircraft, missile and satellite applications, where size, weight, cost, performance, ease of installation, and aerodynamic profile are constraints, low profile antennas may be required. Presently, there are many other government and commercial applications, such as mobile radio and wireless communications that have similar specifications. To meet these requirements, micro strip antennas can be used [1,2]. The expensive
