Power consumption of modern datacenters is increasing rapidly. Databases, especially OLTPs, have become a major application at datacenters. Therefore, power-saving management for OLTP applications has become an important task for user budgets and datacenter operations. A recent report described that disk drives consume about 70% of total power of IT equipment when such large OLTP applications a...

fuel wood provides the main source of energy for cooking and space heating for over 80 percent of households living in kenya. the heavy reliance on the biomass energy has exerted an imbalance in demand and supply consequently resulting in adverse environmental effects in kenya. as part of innovation efforts, several energy-conserving technologies have been developed. a unique cook stove named m...

LTE and LTE-Advanced mobile technologies have integrated discontinuous reception (DRX) power saving method to optimize the power consumption at the user equipment (UE). The DRX method was proposed by the 3rd Generation partnership Project (3GPP), and since then, the traffic behavior has been analyzed in several studies with a standard 3-state DRX model to describe the trade-off between power sa...

This Issue Brief addresses three questions raised by recent trends in personal saving: How are national savings measured and what is the meaning of the trends in measured personal saving rates, given what is included and what is not included in those measures? What is the effect of retirement saving programs--in particular, 401(k) plans and individual retirement accounts (IRAs)--on personal sav...

IEEE 802.16e standard have been designed for both delay sensitive and delay tolerant applications. This paper presents energy-saving strategies by extending unavailability interval for multiple power saving classes simultaneously. The proposed model allows mobile stations to dynamically adopt multiple sleep mode operation or multiple partial sleep mode operation based on the buffer status of po...

the ongoing study aims at a brief pathology on saving in iran's private sector. the factors effect on saving in private sector have been introduced, including oil revenues, real interest rate of banking long-term deposits, ratio of stocks transactions value to gross national production (gnp), proportion of employed population to total population, inflation rate and gini coefficient during ...

—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) ...
