Estimation of Extreme Wind Sped (EWS) is one of the important parameter for planing, design and management of civil structures such as bridges, wind turbines and radio masts etc. This can be achieved through Extreme Value Analysis (EVA) of wind sped data adopting five probabilty distributions. Method of L-Moments (LMOM) is aplied for determination of parameters of the distributions for estimation of EWS. Godnes-of-Fit ests such as Chi-Square and Kolmogorov-Smirnov are aplied for checking the adequacy of iting of distributions to the recorded data. A diagnostic test of D-index is used for the selection of a suitable distribution for EVA of wind sped. The paper presents the Gumbel Extreme Value is beter suited amongst five distributions studied for estimation of EWS for Delhi and Extreme Value Type-1 distribution for Kanyakumari

Although cloud computing has recently attracted significant momentum and attention in both academia and industry users. This is due to noticing drastic change in everyone’s perception of infrastructure availability, software delivery and development models. Representing the step by step deployment from mainframe computers to cloud computing architecture, following the transition throw personal computer, network, client / server, internet and grid computing models. This rapid change towards the cloud computing, has fuelled on this critical issue for the success of information systems, communication and information security. To words the perspective of security, a number of risks and challenges have been introduced regarding relocation to the cloud computing, deteriorating much of the effectiveness of traditional protection mechanisms. As a result the aim of this paper is firstly to introduce some of the paradigm towards cloud computing, application, advantage and drawbacks of cloud computing and secondly to evaluate cloud security by identifying some of the challenges in the cloud computing. The aim of this paper is to provide a better understanding of cloud computing and identifying security requirements in the cloud computing model.
