The Power Generation and Distribution (PGD) system design of the University of Hawaii Small Satellite Program’s Phase III, Ho`okele (Way Finder), is described. The design progression of the PGD system is presented to provide a working reference for small satellite developers. The system is described using the fundamental blocks: Power Generation, Energy Storage and Power Management. Power gener...

In this paper, we propose a wireless system discovery scheme capable of supporting effective device power management by employing a battery-efficient wireless network scanning procedure. Multi-mode terminals must be able to discover other wireless systems and, above all, to execute an inter-system handover in the heterogeneous wireless network environment. The existing methods introduced in rec...

this study attempted to investigate the process and barriers of flow of technical information in kwpa [1] . a survey method was used to collect the data. interviews with some key persons were also conducted. the target population included both experts and technical managers, and the information output of technical departments. descriptive statistics and spearman's rank correlation coefficient w...

Introduction . To optimize the performance of vehicle electrical system, it is necessary to improve control principles and strategies. The may be based on voltage constancy, ensuring battery charge, reducing fuel consumption, etc. Materials methods A distinctive feature first level strategy absence additional sensors in power supply system. Their occurence led emergence second aimed at starter ...

In this paper, we propose a method for finding the optimum information queue length of a palmtop multimedia terminal. which is equipped with semi-batch power management. This optimum queue length is determined by the minimization of power consumption, which is based on the balance of the probability combination of high-power state and low-power state. The low-power states are derived from the “...

social network analysis used to study the relationship between stakeholders and actors in natural resource management has become a scientific approach. the purpose of this study was analysis of information exchange network among organizations engage in the sustainable management of natural resources. results of social network analysis revealed that there is weak relationship among organizations...
