Abstract’ In an extremely wide network, data aggregation reduces the amount of communication and energy usage significantly. Researchers have proposed a new aggregation framework called synopsis diffusion, which is very robust and also it combines multipath routing schemes with duplicate insensitive methods which accurately calculate the data aggregates even in situations of message losses, resulting … Read more

1 Part 1: Track B: Linear Fitting Scheme to Find Best-Fit Values Introduction In a linear regression problem, a mathematical model is used to examine the relationship between two variables i.e. the independent variables and dependent variable (the independent variable is used to predict the dependent variable). This is achieved by using the least square … Read more

Abstract: The main objective of this paper is to develop the artificial neural network control algorithm for the control of DSTATCOM for the improvement of power quality. The presence of nonlinear loads makes the voltage to be deviated and current to be distorted from its sinusoidal waveform quality. Thus harmonics elimination, load balancing and voltage … Read more

ABSTRACT Textual-based password authentication scheme tends to be more vulnerable to attacks such as shoulder surfing and hidden camera, eves dropping, dictionary attacks, social engineering. To overcome the vulnerabilities of traditional methods, visual or graphical password schemes have been developed as possible alternative solutions to text-based password schemes. Most of the graphical schemes are vulnerable … Read more

Abstract- Classification is very important in data mining. It is nothing but categorization of data for its most effective and efficient use. In basic approach to storing data ,data can be classified according to its importance or how often it needs to be accessed. Decision tree is one of the classification technique. Decision tree is … Read more

Abstract: RFID (Radio Frequency Identification) systems are vulnerable to replay attacks like mafia fraud, distance fraud and terrorist fraud. The distance bounding protocol is designed as a countermeasure against these attacks. These protocols ensure that the tags are in a distant area by measuring the round-trip delays during the rapid challenge response exchange. Distance Bounding … Read more

Abstract’ The paper presents to design of 8-bit Arithmetic and Logic Unit and bi-directional shift register by taking the advantage of concept called Gate Diffusion Input Technique(GDI).The bi-directional shift register is designed by using the D-Flip Flop with the concept GDI technique. D-flip flop is a one bit storage element to store a one bit … Read more

Distributed Pair Programming: In distributed pair programming, two person that are developing the code are at different geographical location, and follows the same principal as pair programming where they share single machine instance to develop the software. According to [1], there are two person involved one is called driver and another person is called navigator. … Read more

Visual cryptography, degree associate rising cryptography technology, uses the characteristics of human vision to rewrite encrypted photos. Visual cryptography provides secured digital transmission that is used just for merely the once. the initial photos ar typically utilize by pattern this theme. As the simplest way of special secret sharing technology, it fully was used for … Read more

I have proposed an Economic/Environmental Dispatch (EED) which satisfies the operational power constraint and also considering the pollutant emission and cost of fuel. EED addresses the issue of environment during economic dispatch. First the problem is formulated and Pareto Archive Multiobjective Particle Swarm Optimisation (PAMPSO) algorithm is proposed to deal with this problem. The main … Read more

“Cloud computing is a for empowering helpful, on-interest network access to an imparted pool of configurable processing assets (e.g., systems, servers, stockpiling, applications, and services ) that can be quickly provisioned and released with minimum management exertion or service provider connection. This cloud model is built out of five vital attributes, three administration models, and … Read more

The possibility of non-volatile MOS memory device was recognized. The memory transistor proposed by them was similar to MOS structure, except the gate structure was replaced by a layered structure of a thin oxide I1, a floating gate but conducting metal layer M1, a thick oxide I2, and an external metal gate M2 as shown … Read more

‘ A public cloud provided ‘as a service’ to store the data of the applications data in cloud servers ‘ The client doesn’t have any control over the services which are hosted in the cloud ‘ The main infrastructure is shared with many organizations , but each organizations data has been separated technically so that … Read more

Fusion is a process of combining two or more things together to form a single entity. Fusion processes are stated as follows: A. Levels of Fusion. One of the earliest considerations is to decide what strategy to follow when fusing multiple modalities. The most widely used strategy is to fuse the information at the feature … Read more

Chapter 1 INTRODUCTION Electronic object caching in SWNETs are shown to be able to reduce the content provisioning cost which depends heavily on the service and pricing dependences among various stakeholders including content providers (CP), network service providers, and End Consumers (EC). Drawing motivation from Amazon’s Kindle electronic book delivery business, this paper develops practical … Read more
