Potential induced degradation (PID) is a serious threat for the photovoltaic (PV) industry. The risk of PID may increase with increasing operating voltage PV systems. Although tests are currently standard tests, expansion floating power plants and installation in humid climates show that PID-free modules still sensitive to this type degradation. Therefore, method can detect initial phase before...

Recent information systems (IS) publications reveal an emerging interest in studying postadoptive system use behaviors. Compared to the well-established research stream of IS adoption and initial usage, understanding of IS use behaviors after initial implementation stage is still at its early stage. To further develop knowledge about this phenomenon, this study reviews the IS implementation sta...

Dairy farming now needs more records to be kept for quality assurance as well as for management. Herd fertility management is best brought about through the use of computerised records for each animal that integrate fertility, health and production. The development of dairy information systems over the last 25 years has allowed the creation of databases that give rise to "standards" of performa...

Safety critical computer-based systems are now in widespread use in Defence. A number of current standards such as the UK Defence Standards 0055 and 00-56 and the recently proposed Def (Aust) Standard DR5679 require the use of formal mathematical modeling and reasoning to provide sufficient assurance of safety of system design. The analysis of system design at an early stage is a crucial step i...
