Some CPU scheduling algorithms such as First-Come-First-Serve (FCFS), Shortest Job First (SJF), Priority, Round Robin (R-R), Multilevel Queue(MQ) and Multilevel Feedback Queue (MFQ has been elaborated and assessed on the basic CPU scheduling objectives i.e.; average waiting(AWT), average turnaround (ATT)and average response time(ART), average CPU utilization (AU)and average throughput(AT). Thes...

The pallet repair industry has been growing at significant rates in the United States. It has been estimated that therepair industryreceived 299 million pallets in 2001, and a majority went back into the marketplace as repaired or remanufactured pallets. Many question how well these pallets perform when compared to new pallets. The purpose of this research was to provide a benchmark for the rel...

This work introduces a method for instrumenting applications, producing execution traces, and visualizing multiple trace instances to identify performance features. The approach provides information on the execution behavior of each process within a parallel application and allows differences across processes to be readily identified. Traces events are directly related to the source code and ca...

A simple programming model of distributed-memory message-passing computer systems is rst applied to describe the couple architecture/application by two sets of parameters. The node timing formula is then derived on the basis of scalar, vector and communication components. A set of suitability functions, extracted from the performance formulae, are deened. These functions are shown to be particu...

This extended abstract present findings on measured TCP performance of a range of network stacks. We have found that there are significant differences between the TCP implementations found in Linux, FreeBSD, OpenBSD and Windows XP.

Wireless Sensor Networks used in monitoring and surveillance scenarios are often deployed in areas that are difficult to access. As such they are required to work without any further human interaction and to recover from sensor node failures. The goal of this semester thesis was to get a better understanding of the Dozer network protocol used to communicate in the WSNs maintained by the PermaSe...

This paper proposes how to automatically identify Korean comparative sentences from text documents. This paper first investigates many comparative sentences referring to previous studies and then defines a set of comparative keywords from them. A sentence which contains one or more elements of the keyword set is called a comparative-sentence candidate. Finally, we use machine learning technique...

Much of the debate about comparative employment performance in recent decades has focused on the impact of labor market institutions and policies. A number of studies have found that institutions and policies that restrict or regulate market processes for example, wage compression, employment protection regulations, high taxes, generous unemployment benefits have adverse effects on employment o...

Clustering is an adaptive procedure in which objects are clustered or grouped together, based on the principle of maximizing the intra-class similarity and minimizing the inter-class similarity. Various clustering algorithms have been developed which results to a good performance on datasets for cluster formation. This paper analyze the three major clustering algorithms: K-Means, Farthest First...

The study presented in this article focuses on comparative analysis of Segmentation techniques. Segmentation techniques are applied to extract Region of Interest (ROI) from medical images obtained from different medical scanners such as Ultrasound, CT or MRI. Global thresholding, Adaptive Thresholding, Region grow and Active contour using level set techniques has been used in the proposed segme...
