This research work investigates the influence of the solvent used upon the formation of polymeric photoactive layer. This photoactive layer consists of a blend of poly (3-hexylthiophene) (P3HT) and ...6,6-phenyl-C
61-butyric acid methyl ester (PCBM), to produce P3HT:PCBM (at 1:1 ratio) blend thin films, in which the material solutions are deposited onto clean substrates via spin-coating technique. Three types of solvents were used namely: 100% dichlorobenzene (DCB), 100% chloroform (CH) and 50%:50% mixture of DCB and chloroform. The results reveal that the mixture of solvent produces a better solubility of the polymeric materials compared to that of the pure single solvent.

The CMS Remote Analysis Builder (CRAB) is a distributed workflow management tool which facilitates analysis tasks by isolating users from the technical details of the Grid infrastructure. Throughout ...LHC Run 1, CRAB has been successfully employed by an average of 350 distinct users each week executing about 200,000 jobs per day. CRAB has been significantly upgraded in order to face the new challenges posed by LHC Run 2. Components of the new system include 1) a lightweight client, 2) a central primary server which communicates with the clients through a REST interface, 3) secondary servers which manage user analysis tasks and submit jobs to the CMS resource provisioning system, and 4) a central service to asynchronously move user data from temporary storage in the execution site to the desired storage location. The new system improves the robustness, scalability and sustainability of the service. Here we provide an overview of the new system, operation, and user support, report on its current status, and identify lessons learned from the commissioning phase and production roll-out.
A lecturer as an educator in a college institution obtains professional appreciation for their work through certification of lecturer who is rewarded in the form of lecturer allowance. To obtain a ...lecturer allowance, lecturers are required to report their academic activities. The purpose of this study is to describe the design of web-based lecturer performance reporting applications. In this study the application is modelled with UML modelling (Unified Modelling Language) that describes a system design. The object of research that used as a user of the application is a lecturer of Private Islamic Higher Education. The results of application design show that the system can work well; can process data of lecturer activities among others: education, research, community service, and supporting which then converted to semester unit value (SKS). This lecture performance reporting application is user friendly, easy access, good system security, and have a good data base.
