Energy consumption has become an important issue in the study of processor scheduling. Energy reduction can be achieved by allowing a processor to vary the speed dynamically (dynamic speed scaling) [2–4, 7, 10] or to enter a sleep state [1, 5, 8]. In the past, these two mechanisms are often studied separately. It is indeed natural to consider an integrated model in which a processor, when awake...
The methodology developed provides for a systematic way to find an infinite number of the novel stable bright and dark ‘‘soliton islands’’ in a ‘’sea of solitary waves’’ of the non linear Schrödinger equation model with varying dispersion, non linearity and gain or absorption. It is shown that solitons exist only under certain conditions and the parameter functions describing dispersion, non li...
Weaknesses in several recently proposed ideas about congestion control and avoidance in high-speed networks are identi ed. Both sides of the debate concerning priorreservation of resources versus walk-in service, open-loop control versus feedback control, rate control versus window control, and router-based control versus source-based control are presented. The circumstances under which backpre...
Improving the cooling efficiency of servers has become an essential requirement in data centers today as the power used to cool the servers has become an increasingly large component of the total power consumption. Additionally, fan speed control has emerged in recent years as a critical part of system thermal architecture. However, the state of the art in server fan control often results in ov...
Power consumption is the bottleneck in achieving high performance. Power dissipation needs to be looked into the various levels of the design namely: circuit level, device level, architecture level and system level. With the increase in the networking, network processors (NP) have emerged as platform providing high performance and flexible in building the routers. Its observed from the survey o...
The modelling of wind speed is a traditional topic in meteorological research, where the main interest is on the short-term forecast of wind speed intensity and direction. More recently, this theme has received some interest in the quantitative finance literature for its relationship with electricity production by wind farms. In fact, electricity producers are interested in long-range forecasts...
This paper presents analytical handoff management for multimedia users in a high speed wireless mobile network. We demonstrate the performance of handoffs with mobility consideration using several metrics including the alteration of states prior to reaching a cell boundary, the speed of mobile terminal, and the distance between a mobile terminal and a cell boundary. We mainly focus on the perfo...
Thermoelectric energy harvesting is emerging as a promising alternative energy source to drive wireless sensors in mechanical systems. Typically, the waste heat from spindle units in machine tools creates potential for thermoelectric generation. However, the problem of low and fluctuant ambient temperature differences in spindle units limits the application of thermoelectric generation to drive...
The software industry has been struggling with issues like cost efficiency, development speed and reliability. To attack these problems many techniques have arisen. One of these is the use and reuse of components. Using components in a development process will also bring some problems. When a software company has a large repository of components to choose from there is the problem of choosing s...
PURPOSE The objective of this study was to describe spatial and temporal parameters during gait in pregnant women, and to compare it with women in post-partum and with a control group. METHODS To investigate alteration in natural locomotion, we used an electronic walkway (GAITRite system). Fifty-eight pregnant women (four last months of pregnancy), nine post-partum women and twenty-three heal...
