Cloud computing has almost changed the way of obtaining resources and managing platform as a service. With these improvements, challenges like scalability testing, performance testing is emerging very fast. This paper focuses on the evaluation of scalability of PaaS as well along with that propose a graphical model where SIS (Scalability Improvement System)is proposed in which cache are impleme...

Software testing is indispensable for all software development. In software development practice, testing accounts for as much has 50% of total development efforts. Regression testing has been used to support software testing activities and assure the acquirement of appropriate quality through several versions of a software program. Regression testing, however, is too expensive because it requi...

Original scientific paper As a synchronization method, IEEE1588 standard has been applied in substation, it should be tested and verified ensure synchronization accuracy and node interoperability. A comprehensive testing method for the IEEE1588 is proposed in this paper. Furthermore, IEEE1588 clock testing platform is built to support the proposed testing method. Based on the analysis of the cl...

The reliability of building processes is related not only to the level of performance required but also to their organizational structure. Conditions of turbulence in which constructors operate on site closely interact with the performance of the construction process and particularly with the risk of non-conformance of a building to the performances required. Interaction is characterised by the...

Despite the high skill levels needed to cope with complex technical systems and the pace of technological change, there remain persistent skill gaps in the United States workforce. Organizations are increasingly relying on skill-based programs to encourage and foster employee skill development. Unfortunately, many questions remain about how to make skillbased promotions. Drawing from research o...

The visual analysis of Stereoeletroencephalographic (SEEG) signals in their anatomical context is aimed at the understanding of the spatio-temporal dynamics of epileptic processes. The magnitude of these signals may be encoded by graphical glyphs, having a direct impact on the perception of the values. Our study is devoted to the evaluation of the quantitative visualization of these signals, sp...

The aim of this exploratory study was to detect among decathletes types of specialization with the help of a one sample configural frequency analysis (CFA). The sample consisted of the performances of 514 decathlon athletes, who were ranked among the top 100 athletes of the world from 1984 to 2000. Due to the fact that some athletes were ranked repeatedly among the top 100 world’s best athletes...

Testing of database applications is of great importance. Although various studies have been conducted to investigate testing techniques for database design, relatively few efforts have been made to explicitly address the testing of database applications which requires a large amount of representative data available. As testing over live production databases is often infeasible in many situation...

This is the third in a series of four continuing education articles related to the characteristics of the scintillation camera. Upon completion of this article, the reader should be able to: 1) understand the principles and the necessity of performance testing; 2) have the basic information to establish and conduct a routine testing program; and 3) effectively ensure the installation and perfor...
