Most of Microsoft word documents were transfer or shared via internet by using e-mail or any electronic way. This facility is exploited to send any embedded secret data anywhere. In This paper an efficient method was proposed to hide any text massage with in Microsoft word documents.The initial idea of this method is to exploit the addition three spaces on end of paragraph using for hidden data into it by using the color storage bytes. Two algorithm are proposed and implemented by using PHP language , the first one is to hide the secret message in original text ,and the second is retrieve the original text after the determination of hidden data in it . The comparison of the obtained results between the original text and the text contains the hidden data shows that the two texts are virtually identical.

The task of relevance search is to find relevant items to some given queries, which can be viewed either as an information retrieval problem or as a semi-supervised learning problem. In order to combine both of their advantages, we develop a new relevance search method using label diffusion on bipartite graphs. And we propose a heat diffusion-based algorithm, namely bipartite label diffusion (BLD). Our method yields encouraging experimental results on a number of relevance search problems.

Iris-based biometric authentication is gaining importance in recent times. Iris biometric processing however, is a complex process and computationally very expensive. In the overall processing of iris biometric in an iris-based biometric authentication system, feature selection is an important task. In feature selection, we ex-tract iris features, which are ultimately used in matching. Since there is a large number of iris features and computational time increases as the number of features increases, it is therefore a challenge to develop an iris processing system with as few as possible number of features and at the same time without compromising the correctness. In this paper, we address this issue and present an approach to feature Selection Method.

The main aim of this paper is to create a summation formula amassed with Hypergeometric function.

Based on the concept of the external power system dynamic equivalent for the study system, this paper proposes a novel evolutionary method for the identification of the equivalent’s parameters, comparing the answers of the complete network and its equivalent following the small disturbances which emerged in the study system. The proposed method is demonstrated and compared with the original system using the 10 machines 39 buses New England test system. The comparison shows that the proposed approach can preserve all dynamic properties of the original network.

Matrix laboratory can assist the teaching and research of engineering and science education. This paper mirrors how the tedious analytical method of arriving at a solution of mechanical systems and electrical transients can be made less burdensome using MATLAB. The simulated results show that velocity changes with displacement and time. It also highlighted the frictional force or air viscosity inherent in the system as a result of acceleration or retardation and further exhibited the effect of transients on circuit charge and current respectively. The values of this pedagogical tool will enhance a better comprehension of mechanical and electrical systems.

Nowadays, Information technology (IT) is considered as a very important and most useful part of industry, economic and culture, accounting is the system of recording and summarizing business which provide the users with information in their decision making process this research tries to examine the effect of social factors on IT acceptance to by using TAM model. The research method is descriptivesurvey based on which the author used descriptive and deductive statistic to meet the research goals. The results Keywords : system usage, Perceived usefulness, Perceived ease use, information technology, Social factors and accounting profession. indicate the lack of perceived ease of use among ease accountants.

This paper present a comparative study of performance and emission characteristics of compression ignition engine with different method of using straight vegetable oil. Single cylinder water cooled, constant speed diesel engine which is generally used for water pump or generator sets is used for investigations. During tests, engine is operated with petrodiesel, vegetable oil (at normal room temperature and at 90°C) and vegetable oil-ethanol emulsions at room temperature. The engine performance parameters and emissions are measured at different test fuels from no load to full load conditions.

Nowadays computers education is necessary in every sector whether it is public or private. General applications like Word processor, Spread sheet, Presentations and email usage is demanded during hiring someone. Under development countries like Pakistan where literacy rate is already low, facing these challenges to produce a quality computer professional. Students have to pay huge amount to get a quality computer training away from their doorstep. Private sector is trying their best to fill this gap for professional education but they offered less quality that leads their efforts towards failure. Students have keen interest to get computers professional education that can help in their future life but they came back with frustration due to low quality of courses offered at high cost. In this situation the frustration can be reduced through Elearning Program. In this paper the author try to offer a web based E-learning solution according to current market requirements. This E-Learning solution may give some hope to those who are tired from current situations.
