One of the most important considerations for the current VLSI/SOC design is power, which can be classified into power analysis and optimization. In this survey, the main concepts of power optimization including the sources and policies are introduced. Among the various approaches, dynamic power management (DPM), which implies to change devices states when they are not working at the highest spe...

Recently, a large effort has been made to reduce the power consumed by computer systems. Multiple power states have been defined, and mechanisms have been developed which allow system software to control transitions between these states. Unfortunately, little work has been done to determine effective times to change states. Statistical models of the power utilized by individual subsystems can p...

This paper describes a low power, high performance wearable computing plattform, specifically designed for easy integration into everyday clothing. It combines a heterogenous, distributed, user reconfigurable system architecture, advanced power management features and highly miniaturized, mechanically flexible electronic packaging technology. As a result the WearARM system offers high perfomanc...

Modern software application being built up with standard software components and components developed. If these components are used on mobile devices, the energy consumption must be taken into account at the design. Mobile device power management concepts need a lot of system power information to work satisfactorily. Therefore we propose the Standard Power Estimation Interface for Software Comp...

This thesis extends on a Finnish case study on a Digital Hydraulic Power Management System, which is an example of a cyber-physical system. Such systems may have strict bounds on properties, which can be proven using modeling techniques and verification queries. Scaling of models to arbitrary size is under ongoing research, which this paper explores using the example of the Digital Hydraulic Po...

The increasing penetration of distributed and renewable generators into today’s power systems poses new challenges to power system management and control. Future power system management systems have to balance the mismatch between volatile renewable generation and load as well as to bridge the geographical gap between renewable generators and load centers. For power system modeling, analysis an...

In this study, the relationship between components of knowledge management on the basis of M. Mc olrvy model and social capital has been studied, statistical population consisted of employees of Ministry of Energy, who were selected among employees of Hamedan regional power and were 420 subjects. Research tool is a questionnaire and Spss statistical software is used for data analysis and struct...
