This paper presents two novel heuristic algorithms for the design of wireless access networks. Emphasis was given to the design of CDMA based wireless networks and Fixed Wireless networks. The objectives of these methods are first to place a number of access points/base stations in a number of candidate sites and then to assign a number of fixed wireless terminals to the selected access points/...

Despite construction of powerful parallel systems and networked computational grids, achieving a large fraction of peak performance for a range of applications has proven very diÆcult. In this paper, we describe the components of Delphi, an integrated performance measurement and prediction environment that places system design on a solid performance engineering basis.

The expected functional life of polymers and polymer-based composites subjected to a set of environments and stress conditions is often determined by issues of aging, dimensional stability and durability. The complexity of these issues leads not only to a need for further research developments but also improved methods of application of current physical and chemical knowledge to the design, man...

the present study was aimed to develop and validate a high performace liquid chromatography method for determination of thiocolchicoside and dexketoprofen trometamol in combined dosage form. the proposed hplc method utilizes an agilent eclipse c-8 column (5 µm, 250×4.6 mm) at ambient temperature. a 23 full factorial design was performed for optimization of mobile phase for separation of two dru...

The main goal of a Case-Based Reasoning (CBR) system is to provide criteria for evaluating the internal behavior and task efficiency of a particular system for a given initial case base and sequence of a solved problems. The choice of Case Base Maintenance (CBM) strategies is driven by the maintainer's performance goals for the system and by constraints on the system's design and the task envir...

changes in dietary electrolyte balance influence the metabolic fate of protein and many amino acids. furthermore, acid-base condition is achieved in part by the alteration of dietary amino acids pattern and quantity. therefore, a trial was conducted in a completely randomized design to evaluate performance, carcass characteristics, plasma electrolyte and uric acid concentrations of 19 and 28-da...

Recently, GPUs have also been used plenty in the scientific calculations for high-performance in parallel computing power and low energy consumption. Offering GPU performance prediction models base on Micro-architecture parameters to optimal design in the hardware process of the GPU, has been the subject of prior works. In this article, we defined design space NVIDIA Fermi GPU bigger than the p...

A water jet machining is an industrial tool capable of cutting a wide variety of materials using a very high-pressure jet of water, or a mixture of water and an abrasive substance. This paper addresses the concept of the Intelligent knowledge base system (IKBS) for optimization of product design and manufacturing process for water jet machining in computer based concurrent engineering environme...
