Wireless hosts are usually powered by batteries which provide a limited amount of energy. Therefore, techniques to reduce energy consumption are of interest. One way to conserve energy is to use power saving mechanisms. Power saving mechanisms allows a node to enter a doze state by powering off its wireless network interface when deemed reasonable. Another alternative is to use power control sc...

Slack is pervasive in runs of high performance applications, in the presence of various performance boosting solutions. The presence of slack provides ample opportunities for achieving energy efficiency for high performance computing nowadays. Regardless of communication slack, classic energy saving approaches for saving energy during the slack otherwise include race-to-halt and CP-aware slack ...

The design of mobile GPUs is all about saving energy. Smartphones and tablets are battery-operated and thus any type of rendering needs to use as little energy as possible. Furthermore, smartphones do not include sophisticated cooling systems due to their small size, making heat dissipation a primary concern. Improving the energy-efficiency of mobile GPUs will be absolutely necessary to achieve...

The study examines the effect of transformation ratio in power transmission system on engine efficiency as a function of passenger vehicle velocity (m = 1400 kg) with energy-saving vehicle drive. The study also presents working range in driving phases for energy-saving speed control up to 120 km/h for a simplified overall engine performance map for SI engine. Understanding of the presented cons...

—As the increasing number of access devices, and the complex and changeful of access site and the media, energy consumption of power distribution communication access networks is expected to further grow in the future, energy saving has become a key issue with the development of Passive Optical Networks (PONs). In this paper, we propose a Software Defined Distribution Optical Network (SD-DON) ...

Energy saving is becoming one of the major design issues in processor architectures with multiple functional units (FUs). Nested loops are usually the most critical part in multimedia and high-performance DSP systems. There is a tradeoff between power saving and performance, such as timing constraint and code size requirement, of nested loops. This paper studies how to minimize the total energy...

sustainable architecture is known as an important strategy in recent years and all around the world are cooperating to achieve this by use of natural elements. there are many examples of residential buildings in iran s past and its traditional architecture that the architecture in the interim of paying attention to aesthetic issues and preserving the natural environment acts in a way that meets...
