CREDIT CARD FRAUD DETECTION USING HIDDEN MARKOV MODELS
Abstract: Now a day the usage of credit cards has dramatically increased. As credit card becomes the most popular mode of payment for both online as well as regular purchase, cases of fraud associated with it are also rising. In this paper, we model the sequence of operations in credit card transaction processing using a Hidden Markov Model (HMM) and show how it can be used for the detection of frauds. An HMM is initially trained with the normal behavior of a cardholder. If an incoming cre ....etc

It is shown that several (single-mode) models (PTT, XPP) are basically special cases of the General Network model. The XPP model of Verbeeten et al (2001) is shown to give an identical response to a PTT model at high elongational rates, but the models differ in shear flow at high shear rates. The Giesekus term in the XPP model has actually no effect at any deformation rate except the generation of a second normal stress difference at small shear rates. The possibility of tailoring the shear flow response at high shear rates is explored. The res ....etc

Introduction
The seminar aims at introducing various other forms of computation methods. Concepts of quantum computing, DNA computing have been introduced and discussed, Particular algorithms (like the Shor's algorithm) have been discussed. Solution of Traveling alesman problem using DNA computing has also been discussed. In the seminar aims opening windows to topics that may become tomorrow's mainstay in computer science. Richard Feynman thought up the idea of a 'quantum computer', a computer that uses the effects of quantum mechanics to ....etc

The recent renewed interest on fluid-fuel nuclear systems has stimulated the development of models and methods for the physics of these systems, for both steady-state and transient analysis. The European research project MOST within the 5-th Framework Program has devoted a considerable effort to the assessment of models and computational tools for molten-salt systems. The seminar addresses the activities carried out at Politecnico di Torino on the neutronics of fluid-fuel systems. The basic physical phenomena connected to the motion of the fuel ....etc

ABSTRACT

VEHICLE HANDLING, STABILITY,AND BIFURCATION ANALYSIS FOR NONLINEAR VEHICLE MODELS

Vehicle handling, stability, and bifurcation of equilibrium conditions were studied
using a state vector approach. The research provided a framework for an
improved method of vehicle handling assessment that included non-linear regions
of performance and transient behavior. Vehicle models under pure lateral slip,
constant velocity, and constant front steer were developed. Four-wheel, two-axle
vehicle models were evolved from si ....etc

This a very simple radio.Only five parts are here for the radio.



Lazer works in high voltage supply.How can we make high voltage out of 220/110 V AC.Here gives the circuit.You can use this to make high voltage supply.But prevention should be taken to avoid shoking hazards.
The circuit takes 115 V supply and gives to step up transformer. Three diodes and three capacitors are used to eliminate the ripples of AC.




The main components are microphone, antenna, 2N2222A NPN Transistor. The range of the transmitter when r ....etc

ABSTRACT
The concept of a middleware was introduced to facilitate communication between entities in a heterogeneous distributed computing environment. The main task of an event-based middleware is to disseminate data to all interested parties in a largescale distributed system. Hence, an event model is needed to describe how data, and interest in that data, is expressed in the system i.e. event publication and event subscription respectively. In our system, we represent an event as an object and the event model is illustrated using a sample a ....etc
