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.

Abstract: This paper is concerned with the design and development of a simple fuzzy system for modeling of ill-defined dynamical systems. This system, which is represented as a feed forward neural network, is able to incorporate qualitative and quantitative information. Supervised linear back propagation learning algorithm has been applied to model a system through identifying the fuzzy parameters. This adaptive fuzzy system is implemented as an identifier of dynamical systems. The system performance has been evaluated for different simulated systems to demonstrate the application of the proposed system to identify the dynamics of linear and nonlinear time-invariant and time-variant systems.

Research Title: Modeling an Interactive FMS Scheduler Using Colored Petri Nets

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

Faculty: Engineering and Technology

Abstract: A new hierarchical model based on CPN for general FMS scheduler is presented. The designed model is partitioned into two levels to face the complexity of the manufacturing systems. The first level in the model is the cell-level, which supervises the jobs scheduling between cells. The second level is the machinelevel, which supervises the scheduling of the manufacturing jobs between machines inside the active cells. The goal of the model is to interpret the output of the manufacturing route planner into graphical representation and to achieve the sequencing, dispatching and monitoring the real time execution of these manufacturing plans. Also the proposed CPN model generates feedback status to monitor the abnormal conditions. Sub CPN priority structures are embedded in the main model to control the election from the competitive jobs to use the limited resources in the system. The hierarchy organization will enhance the real time response of the sequencing and monitoring capabilities. The designed scheduler has been evaluated for different case studies and the achieved results are very encouraging.
