This study investigates the effects of gender on aggregate saving. We test the hypothesis that shifts in women’s relative income, which can affect their bargaining power within the household, have a discernible impact on household saving and, by extension, gross domestic saving, due to differing saving propensities by gender. The empirical analysis is based on panel data for a set of semi-indus...

The wide spread use of IEEE Wireless LAN 802.11 in battery operated mobile devices introduced the need of power consumption optimization while meeting Quality-of-Service (QoS) requirements of applications connected through the wireless network. The IEEE 802.11 standard specifies a baseline power saving mechanism, hereafter referred to as standard Power Save Mode (PSM), and the IEEE 802.11e stan...

In light of recently stirred energy consumption concerns, we investigate the opportunities for power consumption reduction in Grids. Considering real life Grid traces, we note considerable fluctuations in load. We consider a peak load dimensioning strategy to derive how much servers to install in computational Grids. In lower loaded periods, there is a potential to save energy by dynamically po...

Broadcasting live digital TV to a small battery-powered handheld device is very challenging. One of the most promising technologies to provide such services is DVB-H (Digital Video Broadcasting over Handheld). Power consumption has always been one of the most crucial challenges for handheld devices. In this paper, a novel Adaptive Modulation and Coding (AMC) framework is proposed for DVB-H syst...

During the last decade mobile communications increasingly became part of people’s daily routine. Such usage raises new challenges regarding devices’ battery lifetime management when using most popular wireless access technologies, such as IEEE 802.11. This paper investigates the energy/delay trade-off of using an end-user driven power saving approach, when compared with the standard IEEE 802.11...

Energy efficiency is one of the most important attributes in sensor network protocols. In sensor nodes, communication related activities consume the major share of battery energy. Therefore, judicious choice of transmit power and frame size are very important to maximize the energy efficiency and hence the lifetime of nodes. While there have been a few recent studies on transmit power control i...

The CORDIC algorithm provides an efficient method of computing trigonometric functions by rotating a vector through some angle, specified by its coordinates. This rotation is obtained by performing a number of micro rotations through elementary rotation angles, into which the total rotation angle has been decomposed. This paper presents the design and implementation of a runtime reconfigurable ...
