Power quality requirements has several requirements that affect on the electric power network. Expansion of nonlinear loads in wide applications like LED unit’s production especially lower power units encourage the researches to modify the technical characteristics of these units. The actual analyses of LED unit’s performances is carried out to maximize their advantages to increase their applica-tions in our life. So. This paper focus on internal performance of indoor LED units through experimental procedures using Ti200 thermography Fluke to measure the output heat from proposed samples of LEDs units. Power dissipated of tested units has been studied. Also, correlated color temperature of tested units have been evaluated. One sample of CFL tested unit is selected for compar-ison between LED’s units. Tenmars Lux/FC light meter is used to measure the luminance of LEDs units that have different operating hours. The analysis results are discussed and concluded.
Objective: Globally, the inadequate level of knowledge sharing is considered as an increasing concern among educational institutes, impacting educational quality and job performance. Thereby, the study aims to assess the association between behavioral intentions and knowledge sharing by using the Theory of Reasoned Action (TRA). It also examines the influence of the demographic factors on knowledge sharing behavior. Methods: A cross-sectional design was used in this study including a total of 630 academicians from the four educational institutes (Universiti Malaysia Sarawak (UNIMAS), Universiti Teknologi MARA Sarawak, Universiti Putra Malaysia, Bintulu and Politeknik Kuching) based on a survey approach. The collected data were analyzed statistically using PLS SMART- SEM. Results: The results revealed a significant impact of age, gender, work experience, designation, and education on behavioral intentions and knowledge sharing. It also showed a direct association between behavioral intention and knowledge sharing. Conclusion: The study concludes that collaborative practices should be encouraged among academicians for creating a knowledge sharing culture.
The world wherein we live has witnessed diverse improvement brought about by the technological advancement. Several more will yet be born in the next few years going by the spate of development in Information Technology. Cyber physical systems (CPSs) have made these quite attainable. However, controlling access has been a major drawback to embracing this technology swing. This paper offers an enhanced access control in CPS with biometrics. Keywords: cyber physical system, authentication, biometrics, bimodal and identity management.
Abstract Nigerian institutions of higher learning are post-secondary schools whether online or within the four walls of a building. More often than not, they are run with students needing to complete assignments or making researches that require laptops and other computing devices usage which are not easy to come by. Students then get into theft of these computing devices and still use same in the same institution which may not necessarily be in the same department. Tracking a stolen computing device has become a major problem that the security outfit cannot effectively handle by manual search which necessitate a robust but simple solution proposed by this research.
