The rising number of mobile devices increase the interest in longer battery durations. To increase battery duration, researchers try to improve e.g. different hardware components, such as processors and GPS for lower energy consumption. Frequently, software optimization possibilities to save energy are forgotten. Hence, an approach is shown to reduce energy consumption of applications by reengi...

In order to reduce energy consumption of data centers while employing infrastructure resource effectively, a comprehensive resource management method using an improved online energy saving mapping algorithm for virtual machines of data centers is proposed. An intelligent feedback management framework is built for online resource optimization. We propose reinforcement learning and threshold base...

Microgrid works as a local energy provider for domestic buildings to reduce energy expenses and gas emissions by utilising distributed energy resources (DERs). The rapid advances in computing and communication capabilities enable the concept smart buildings become possible. Most energy-consuming household tasks do not need to be performed at specific times but rather within a preferred time. If...

Energy consumption has become one of the important factors in digital systems, because of the requirement to dissipate this energy in high-density circuits and to extend the battery life in portable systems such as devices with wireless communication capabilities. Flip-flops are one of the most energyconsuming components of digital circuits. This paper presents techniques to reduce energy consu...

Abstract. In this paper we present measurements of energy usage of standard office computing equipment. Using a data trace lasting for all of March 2012 we analyse the energy use of office equipment such as desktop computers, a printer and a fridge. The interest in a more detailed knowledge of the energy usage patterns of these appliances is driven by the desire to manage, and if possible reduc...

To control the quality of reverse osmosis (RO) product water and reduce operational costs and environmental impacts by increasing the system’s energy efficiency, it is necessary to identify the influence of process parameters on energy consumption and permeate water quality. This paper introduces a case study focused on the application of Design of Experiments (DOE) method in an industrial-scal...

Energy is an important constraint for battery-operated embedded Java environments. In this work, we show how the garbage collector (GC) can be tuned to reduce the energy consumption of Java applications. In particular, we show the importance of tuning the frequency of invoking GC based on object allocation and garbage creation rates to optimize leakage energy consumption. We reduce the leakage ...

Cyber–physical cloud systems (CPCS) are extensions of cyber–physical systems (CPS) that expand the cyber-part and distribute it on-device and in-cloud. CPCS are considered large-scale heterogeneous distributed cloud computing systems that support execution of multiple workflows. This study aims to reduce the energy consumption of multiple real-time workflows on CPCS and it contains two objectiv...

Main memory has become one of the largest contributors to overall energy consumption and offers many opportunities for power/energy reduction. In this paper, we propose a new memory organization, called Power-Aware Cached-DRAM (PA-CDRAM), that integrates a moderately sized cache directly into a memory module. We use this cache to turn a memory bank off immediately after a memory access to reduc...

Over half of the total electricity consumption is used in buildings. Air-conditioning and electric lighting are the two main resources of electricity consumption in high rise buildings. One way to reduce electricity consumption would be to limit heat gain into buildings, therefore reduce the demand for air-conditioning during hot summer months especially in hot regions. On the other hand natura...
