In this paper, we tackle the problem of peak and average power optimization in high-level synthesis. Because of the quadratic relationship of supply-voltage to the dynamic power consumption, voltage scaling is considered as the most efficient technique for reducing power consumptions in CMOS circuits. We present an MILP formulation for the scheduling problem using multiple supply-voltages in or...

We propose an energy-balanced allocation of a real-time application onto a single-hop cluster of homogeneous sensor nodes connected with multiple wireless channels. An epoch-based application consisting of a set of communicating tasks is considered. Each sensor node is equipped with discrete dynamic voltage scaling (DVS). The time and energy costs of both computation and communication activitie...

The transfer of prerecorded, compressed variablebit-rate video requires multimedia services to support large fluctuations in bandwidth requirements on multiple time scales. Bandwidth smoothing techniques can reduce the burstiness of a VBR(Variab1e Bit Rate) stream by transmitting data at a series of f i e d rates, simplifgzng the allocation of resources in video servers and the communication ne...

This study focuses on developing fully functional cutting stock software by utilizing an improved multi-phase heuristic algorithm to find the optimal solution for the cutting material. Issues which commonly appear in real-world cutting stock applications are also discussed

Standardized and objective design criteria for evaluating web-based learning platforms can effectively distinguish the quality of a platform and, therefore, contribute in improving web-based learning outcomes. This is a two-phase study, in which Delphi technique and heuristic evaluation were employed in the first phase to develop the evaluation criteria and scale of web-based learning platforms...

A common form of a hyper-heuristic is a method that controls a search process which uses neighbourhood operators. There have many studies showing that hyper-heuristics are reusable for solving unseen problem instances not only from a particular domain but also different problem domains without requiring any change. However, generally hyper-heuristics have been considered as part of time-contrac...

In this paper, we present a methodology to use utilization-based admission control in guaranteed real-time communication in a scalable fashion. We make admission control scalable by using a configuration-time test to determine a safe utilization level of servers. Admission control at run-time then is reduced to simple utilization tests on the servers along the path of the new flow. Furthermore,...

Planning out maintenance tasks to increase the quality of Web applications can be difficult for a manager. First, it is hard to evaluate the precise effect of a task on quality. Second, quality improvement will generally be the result of applying a combination of available tasks; identifying the best combination can be time-consuming. We present a general approach to recommend improvements to W...
