Green computing is a topic that receives a great amount of interests in the past few years. Energy proportionality is a principal of ensuring energy consumption is proportional to the system workload. Energy proportional design can effectively improve energy efficiency in computing systems. In this paper, we present an energy proportional model based on queuing theory and service differentiation in server clusters. The presented scheme provides controllable and predictable quantitative control of power consumption with theoretically guaranteed service performance. The preliminary simulation results indicate the effectiveness and limitations of the energy proportional model under different workloads and energy consumption curves. The most interesting finding in this paper is the trade-off between energy and performance in cluster systems.

In grid computing a loosely coupled and virtual computing infrastructure is created out of a collection of connected heterogeneous processors sharing various combinations of resources. It is pertinent to note that African Small and Medium Enterprises (SMEs) cannot participate in the global market using the current e-business solution due to the lack of or nonexistent infrastructure to support such services. In this paper, we propose a grid service based solution that is indigenous to African SMEs and technologically tailored to meet their local needs. The solution is based on an Application Service Provider (ASP) grid framework. The framework is specified using Universal Modeling Language (UML).

Cooperative mobile robots have recently been gaining importance within the field of robotics. It's been proven that collaborative robots can do tasks in a faster and more reliable manner than a single robot can. Additionally, recent advances in distributed coordination algorithms have dramatically improved the feasibility and suitability of cooperative approaches. This has lead researchers to develop Inter-robot communication frameworks. While several frameworks have been introduced, one of the most common is the Service-Oriented Architecture (SOA). However, the suitability of SOA for collaborative robotic communication has not been fully evaluated. In this paper we evaluate the SOA from an overhead perspective against non service-based architectures in a wireless environment. Our evaluation is based on performance suitability, which is determined by measuring throughput and delay for different numbers of mobile robots sharing real time data.

Matrix multiplication operations are heavily used in communication systems, video, signal and image processing applications such as echo cancellation, adaptive beamforming, and Multiple-Input Multiple-Output (MIMO) systems, and are also used in matrix factorizations such as Cholesky, LU, QR and DCT. However, it is challenging to implement a high speed matrix multiplication operator for large matrices due to the fact that the number of multiplication operations grows rapidly with functions of n3. This paper presents the implementation of a reconfigurable pipelined high speed and high precision matrix multiplication module designer for large matrices on Xilinx Virtex-5 and Spartan 3E FPGAs using high speed memory interface for data transfers.
矩阵乘法运算大量用于通信系统、视频、信号和图像处理应用，如回波抵消、自适应波束形成和多输入多输出(MIMO)系统，也用于矩阵分解，如Cholesky、LU、QR和DCT。然而，对于大型矩阵，由于乘法运算的数量随着函数n3的增长而迅速增长，因此实现高速矩阵乘法运算是一项挑战。本文介绍了在Xilinx Virtex-5和Spartan 3E fpga上采用高速存储接口进行数据传输的可重构流水线式高速高精度矩阵乘法模块设计器的实现。

This paper describes a new approach for locating transcription related signals, such as promoter sequence in nucleic acid sequences. Transcription Factor (TF) and corresponding polymerase binding to their DNA target site is a fundamental regulatory interaction. The most common model used to represent TF and polymerase binding specificities is a position weight matrix (PWM) [1], which assumes independence between binding positions. However, in many cases, this simplifying assumption does not hold. In this paper, we present a statistical filter model based on Chi-Square (χ2) distance [2], which is a statistical distance metric between the profiles of component vectors. It is a novel statistical method for modeling TF-DNA and polymerase-DNA interactions. Our approach also uses a generalized correlation algorithm to evaluate the combination coefficients for the filter bank. Simulation results show that the proposed approach identifies promoter sequences better than the PWM model method and Chi-Square (χ2) distance model.

This paper presents the preliminary results of ambulatory electrocardiogram (ECG) devices for the automated detection of myocardial ischemia. We focus on the reduction of interfering artifacts such as baseline wander and motion artifacts that corrupt ambulatory ECG signals and affect accuracy of ST analysis. Several digital signal processing techniques are developed for testing recorded ECG signals. Computer simulation results are presented to show feasibility of these life-saving devices.

We have developed a data acquisition unit (DAU) for continuous, low noise measurement of photocurrent from low shunt resistance photodiodes. The system is intended for use with a glucose sensor as part of a continuous glucose monitoring system. This paper describes only the design of the photocurrent measurement system and biocompatibility issues are beyond the scope of this paper. The DAU is comprised of a glucose sensor, analog circuitry for signal conditioning, and delta-sigma analog to digital converters (Δ-Σ ADCs). The glucose sensor operates in the near infrared (IR) region where glucose has absorption features that allow concentration measurement. The sensor is comprised of two IR LEDs, a glass fluid chamber, a linearly variable bandpass filter, and a 32 element photodiode array. IR light propagates through the fluid chamber containing analyte and the filter, impinging on the photodiode array. Transimpedance amplifiers (TIAs) convert the photodiode photocurrents into voltages that are sampled by the ADCs. We developed a noise model that predicts the noise characteristics of the system. In this paper we use low noise metal film resistors to verify the DAU noise characteristics in preparation for future use with glucose sensors. A high signal-to-noise ratio (SNR) is needed to accurately quantify the concentration of glucose. The SNR available is limited by the low luminosity available at the photodiodes and the low impedance of the photodiodes (Rpd)

Electrical energy is a vital resource for any developing nation. To meet the growing demand for electricity, power generating plants of all types are being installed. Even then, the gap between the supply and demand is continuously increasing due to the depletion of natural resources. To overcome the problem of energy crisis, the generation of electricity from industrial wastes is most significant. This is one of the alternative ways to overcome this problem. In this paper, a novel methodology is proposed for electricity generation, using the waste gases produced during the manufacturing process in large industries and factories. The generation of electricity in the proposed method needs small turbines which rotate on passing high pressure waste gas from the exhausts. It is considered as a very significant method of electricity generation.

This paper addresses challenges in managing complex automotive powertrain control systems by employing a heuristic method to determine complex setpoints. Two main areas of focus are the fuzzy determination of the driver characteristics and the gear selection for discrete automatic transmissions. The driver characterization determines how aggressive or docile a driver is and has a weighted impact on the gear selection. The gear selection process captures transmission performance fundamentals and infuses them with logic to eliminate undesired or physically impossible gears.
