The effect of memory hierarchy on the overall performance of multi-issue modem Processors (superscalar processor) depends on multiple interact approaches . This performance is more sensitive to the cache organizations and its trade offs. This paper evaluates the performance impact of memory configuration on modem superscalar processors by investigating the use of extra buffers and external queues between pipelines, for the out-of-order hardware architecture with bigger sizes. For a combined effect on the performance improvement, an experimental framework has been suggested using SPEC benchmarks and SimpleScalar simulator. Effects of increasing DLl and ILl cache sizes, 'higher associativity, larger block size, increasing the RUU size and increasing the IFQ on IPC and the cache miss ratio have been illustrated. The objective is to achieve a performance level close to that of an ideal cache with low hardware cost and suitable for most recent superscalar techniques.

This paper presents the design, modeling and implementing of an electronic percentage differential relay that can be used in the protection of different power system components, such as transfomers, bus bars, generators and motors. The design of the electronic circuits, providing the characteristic of the percentage differential relay and signal conditioning to reduce possible errors and increase relay margin, has been carried out using the Electronics Workbench program. A 3-ph static switch is designed and implemented to provide simple and effective tripping out instead of the conventional mechanical contactor. Sirnulink program has been used to simulate and analyze the overall system for the protection of a 3-ph transformer, validating the proposed system for real implementation. The experimental set-up has been implemented and tested, showing the effectiveness of the proposed relay.

The paper presents a computer oriented analysis and procedure for computation of dynamic motion of free conducting particles in electric fields between diverging conducting plates with high voltage DC in GIs. Non-linear dynamic equations of the spherical particle motion was estimated numerically by using Rung Kutta method and graphically visualized. It was found that when the particle is placed on the horizontal electrode surface, the particle progresses towardes a higher electric field region by the effect of coulomb force and electrical gradiant force. This study includes the influence of the most important design parameters on the particle motion, such as applied voltage magnitude, particle density and dimensions, initial particle position and plate angle.

In this paper, we have proposed an adaptive interface agent, called the AdAgen that collaborates with trained agents using neural network to build the software interface agent to detect fractures in long bones. The software agent that provides a semi-intelligent system learns by the "Customizer Dialog "from the user's interests, goals and general preferences. A major problem with the learning approach is that the agent has to learn from scratch and thus takes some time becoming useful. Secondly, the agent's competence is necessarily limited to the actions it has seen the user perform. When the proposed AdAgen is faced with an unfamiliar situation, the agent consults its peers who may have the necessary experience to help it. Thus, the proposed framework can alleviate the mentioned problems. The simulation results have shown how the neural network of the collaborating agents can help maintain the performance for automatic detection of fractures in leg radiograph.

One of the most important characteristics of mobile ad hoc networks is the limited bandwidth, which is considered as a bottleneck. This prompted us to study the channel capacity and the utilization of this capacity by the different types of packets in wireless ad hoc networks. This paper presents the results of a detailed packet-level simulation comparing for multi-hop wireless ad hoc network routing protocols. The simulation will be pe$ormed subject to various numbers of movement scenarios and trafic pattern.

Autonomic Computing is emerging as a significant new approach for the design of computing systems. Its goal is the production of systems that are self managing, self-healing, self-protecting and self-optimizing. Achieving this goal will involve techniques from both Software Engineering and Artificial Intelligence. This paper presents a novel concept to the autonomic computingjield, known as the autonomic property manager. The autonomic property manager is an autonomic manager that is capable of maintaining the management of any of the autonomic computing properties. For each property of the autonomic system an autonomic property manager will be dedicated to handle the duties of this property, i.e. a property keeper. In this paper we present a brief description for our proposed design of one autonomic property manager, namely the autonomic resource optimization manager which is responsible for managing the optimization of all the modules registered under its domain. By setting a specialization for each autonomic manager we can expect better performance and details abstraction.

In this paper, a method of accelerating the speed of Convergence of a blind equalization algorithm is examined. It is shown that as in conventional equalizers the orthogonalizing properties of lattice algorithms make them appear attractive in blind equalization of a channel. The lattice is applied to a newly proposed blind equalization algorithm [I], [2], known as soft-constraint satisfaction multi-modulus algorithm (SCS-MM-I). Experiments show that the introduction of a stochastic gradient lattice structure in SCS-MM-I results in an increase of convergence rate by an order of magnitude.
