Abstract: In the recent past, one of the problem that got wide attention is the power system instabilities with the lack of new generation and transmission facilities and increase in the load demand of electrical power is continuously rising at a very high rate, due to rapid industrial development. Power quality is the main problem that the industry is facing today. Power electronics and advanced control technologies have made it possible to reduce the power quality problems. Among power system disturbances, voltage sags, swells and harmonics are some of severe problems to the sensitive loads. The series compensation method is best suited to protect such loads against those disturbances The series compensator device thyristor controlled series capacitor is used for improving power quality of power system. The role of the compensator is to mitigate the effects of voltage sag. The thyristor controlled series capacitor method approach is different from another conventional method and provide effective solution in power system. A control strategy for the Series Compensation is developed to regulate power flow and minimize the losses in the power system. This is achieved through phase adjustment of load terminal voltage. It leads to an increase in the ride through capability of loads to the voltage sags/swells. In this thesis work, results show a comparative study of output voltage across a nonlinear load using Thyristor Controlled Series Capacitor device control  through PWM Generator six pulses control and Thyristor Controlled Series Capacitor control  through firing angle control  for the reduction of voltage sag in transmission line. The simulation results showed that the proposed series compensator was efficient in mitigating voltage sags and improve the power quality of power system. This approach is different from conventional methods and provides effective solution. If this method is enhanced in future could provide much more improved power quality.

Abstract: The internet becomes most popular mode of payment for online transaction. Banking system provides e-cash, e-commerce and e-services improving for online transaction. Credit card is one of the most conventional ways of online transaction. In case of risk of fraud transaction using credit card has also been increasing. Credit card fraud detection is one of the ethical issues in the credit card companies, mortgage companies, banks and financial institutes. The most used technique in this field is the Hidden Markov Models (HMMs) which is a statistical and extremely powerful method. HMM statistical tool used for modeling generative sequences characterized by a set of observable sequences. Observation probabilistic in an HMM Based system is initially studies spending profile of the cardholder and followed by checking an incoming transaction against spending behavior of the cardholder we can show clustering model is used to classify the legal and fraudulent transaction using data conglomeration of regions of parameter , HMM based credit card fraud detection during credit card transaction. We presented experimental result to show the effectiveness of our approach.

Abstract: Cloud computing technology drawn the attention of IT world and is the changing the focus of enterprises. A high percentage of internet users today are already utilizing aspects of cloud computing in their normal daily workflow. Cloud computing gained attention due to the growth of internet technologies, reduced costs of storage and processing, growth technologies of visualization, SOA (Service Oriented Architecture) and advancement in internet security. Cloud computing security is one of the main challenges in cloud computing. An organization can decide to adopt cloud only on based on benefits to risk ratio. This paper is focused on the security issues of cloud computing. Before analysing the security issues, the definition of cloud computing and brief discussion to under cloud computing is presented. Then discusses the components that affect the security of the cloud then it explores the cloud security issues and problems faced by cloud service provider and some solution for security issues.

Keyword: Cloud Computing, Cloud Security, Cloud Security Issues, Cloud Legal Issues.
