It is designed to assist the designer in the sizing ofPV （photovoltaic） installations. The programming structure and physical models implemented within this tool are described, and several case studies are proposed to highlight its relevance. The predicted yearly electrical energy production of grid-connected PV plants is discussed. In particular, the predicted performance of such plants is compared with that given by the PVsyst software. PVLab has a high level of flexibility, allowing its physical models and databases （e.g., meteorological data） to be modified according to the user＇s needs. This is made possible through the use of expertise applied to all of the computing steps, and to the MATLAB development environment. The user＇s ability to control the source code itself will allow much greater progress to be made in the field of renewable energy applications than with PVsyst, which is currently the commercial reference.展开更多

The number of online news readers is rapidly increasing along with the popularity of the Internet. However, only sources that emphasizes the element of credibility will be accepted by the readers. This study was conducted to determine the credibility of online news; to identify the relationship between online news credibility and youth acceptance. Using a quantitative approach, a total of 400 youth selected to participate in the study out of the 68,000 population in Selangor. The data was analyzed using Statistical Package for Social Science （SPSS） version 21.0. This study shows that a group of young women were the common group who seek and read online information. Based on the findings too, online news in Malaysia are less credible. Although the online news is less credible, the results shows that youth read online news because the contents are current and up to date. Further, result of the Pearson＇s correlation test shows that the more credible elements available in online news, the more that medium is accepted by youth.展开更多
