Abstract: Software testing is a pervasive activity in software development. Testing is widely used to reveal bugs in real software development and is also an expensive task. Testing is expensive due to the fact that it takes very long time to execute the whole test suite. The initial test suite is very large in size and has redundant test cases. So it is necessary to apply some selective techniques in order to reduce the large size of the initial test suite to a manageable size and make it feasible for practical execution. In this study, Hierarchical clustering approach is presented and implemented on the initially generated test suite in order to reduce its size and partition it, into a fixed number of clusters. Here, a branch coverage criterion is selected as the code coverage criteria and for the determination of the number of clusters.

Abstract: In this project, Analysis of Tubular tall building has been done using ETABS. It has been presumes that, the only periphery Columns essentially take part in resisting Wind & Earthquake forces and the interior columns transfer gravity load to foundation. This assumption work fairly well in resisting forces. When the outer tube is subjected to Wind & Earthquake forces the flange columns experience the shear lag phenomenon. Also, in this research, we tried to study the maximum deflection & Inter-storey drift, of the tube without and with shear wall and other patterns of shear panels. It has been observed that more shear panels did not cause necessarily displacement of structures but the type of arrangement had important criteria as well.

Abstract: The purpose of this research is to review the use of social networks and its negative effect among students especially college and university students while on the study. Social networking is an interconnected system through which alliances are formed, help is obtained, information is transmitted, and actions taken to achieve certain results. Electronic communication is emotionally gratifying but how do such technological distraction impact on student’s academic performance and also health threat? Because of social media platform’s widespread adoption by students, there is an interest in how social network (especially Facebook) is related to academic performance and health. Today social network sites are running the future and carrier of students. Social network sites were only an electronic connection between users, but unfortunately it has become an addiction for students. This paper examines the negative effects of social networking on student’s academic performance and health threats.
