Research Title: Unified Matrix Processor Design for FCT-Based Filtering, Convolution and Correlation of Signals

Faculty: Engineering and Technology

Abstract: A new unified matrix processor for the main DSP discrete procedures: convolution, correlation functions and filtering of signals based on discrete cosine transform (DCT-II), is proposed and described. It is shown that these procedures can be computed using the same building blocks which give the processor universal computational structure property. The computational complexity analysis of the proposed processor shows that the FCT-based matrix processor for N- point convolution and correlation computing allows a reduction by 2N - 3 real multiplications and N - 2 real additions in comparison with other processors of the same class. The architecture of the processor supports the classic schema for computing DSP procedures: (Two DCT spectrums + product of cosine spectrums + IDCT transform). The proposed architectures employ simple Processor Elements (PE) that require real multiplications and additions.

Abstract: The paper presents the design and evaluation of an Active Router (AR) architecture, which provides flexibility for the development of future network services. The hardware is based on a personal computer with 2GHz, Intel P4 processor. The designed AR depends on the use of Windows OS, enhancing the Active Network Encapsulation Protocol (ANEP) and the efficient use of C++ programming. Windows OS and C++ language are rarely used in such projects due to complexity of kernelmode and network-oriented programming requirements. Enhancing ANEP gains novel service composition scheme. Finally, the success of the AR architecture and prototype implementation is evaluated by means of a practical application.

Research Title: The State of Engineering Postgraduate Studies in Iraqi Universities

Abstract: Higher Education in Iraq goes back to the first half of the last century. On the other hand engineering postgraduates did not start seriously until around 1970. The environment in which the postgraduate studies had developed in was far from being ideal or anywhere near normal. There was the Iraq-Iran conflict 1980-1988, the 1991 Gulf conflict followed by the sanctions of 1990- 2003, then the occupation of the country in 2003 and the catastrophic aftermath that followed which included a massive brain drain of the Iraqi academia. All these negative factors contributed immensely to stun the actual development of the postgraduate studies in general, but had a particular negative impact on the engineering postgraduate studies. This chapter will address the background of the education system in Iraq and identifies the general challenges facing any revitalization of the postgraduate studies with special focus on engineering postgraduate studies. A road map for the revitalization of the postgraduate studies will be suggested.

Research Title: Teaching Computer Organization and Architecture Using Simulation and FPGA Applications

Author: Kasim Mousa Al-Aubidy, Published Year: 0

Faculty: Engineering and Technology

Abstract: This paper presents the design concepts and realization of incorporating micro-operation simulation and FPGA implementation into a teaching tool for computer organization and architecture. This teaching tool helps computer engineering and computer science students to be familiarized practically with computer organization and architecture through the development of their own instruction set, computer programming and interfacing experiments. A two-pass assembler has been designed and implemented to write assembly programs in this teaching tool. In addition to the microoperation simulation, the complete configuration can be run on Xilinx Spartan-3 FPGA board. Such implementation offers good code density, easy customization, easily developed software, small area, and high performance at low cost.

Faculty: Engineering and Technology

Abstract: The PM motor drive systems are becoming particularly popular in many industrial applications. They have many of the desirable performance characteristics of both the AC and DC drive systems. In this paper, a fuzzy logic controller is proposed for the real-time control of a Sensorless PM drive system. An implicit detection method has been used to detect the rotor position and to measure both the rotating speed and internal load angle. The results given in this paper demonstrate the capability of such a drive system in applications where simplicity, reliability and stability are more important issues. Furthermore, the proposed hardware and software design is simple and can be implemented by a single-chip microcontroller for real-time applications.

Abstract: Premature infant incubator system is a vital and critical area because it deals with premature infant or illness baby. It is essential to detect any abnormal conditions occur in the premature infant incubator system as soon as possible. Temperature, humidity, and oxygen concentration are the main parameters must be control in the premature infant incubator system. In this paper novel technique by using Artificial Neural Network ANN is used in order to simulate the premature infant incubator control system by implementing the back propagation method. Sensors are used to indicate temperature, humidity, and oxygen concentration of the incubator internal environment. Sensors output are entering to the ANN, which identify the corresponding case and decide the suitable reaction upon previous training. The proposed ANN premature incubator control system in all conditions that can occur in the premature infant incubator environment proved right decision.
