M.Ing. / A large number of machine tools in use today are worn and can not produce the correct tolerances as a result of the inaccuracy of the structure. A device was developed to assist in the solution to the problem. The study of the development of this device includes several different fields. An entire prototype scale model of a grinding device is developed, with components including a control system and a developed sensor. The control system consists of circuitry and programming. The programming has been done in Visual Basic. The circuitry includes driver circuits for DC motors as well as pulse width modulation circuits and filters, amplifiers and comparators for the newly developed sensors. The sensor developed is an optical device, which can sense the deviation of a cable for reference for the movement of the device. A combination of the above components into a unit and the provision for factors, such as grinding forces and vibrations, which influence the operation of the device, are presented. Furthermore, an analytical model is suggested for the prediction of the system's behavior.

If the rotor of an induction motor is not concentric with the stator then an electromagnetic force is generated in a direction that will increase the eccentricity. This is called unbalanced magnetic pull (UMP). The first part of the work presented in this dissertation develops theoretical models which allow the calculation of the UMP in cage induction motors due to static rotor eccentricity. These account for any winding configuration including parallel stator winding connection. The second part of the work verifies the models experimentally using two different cage induction motors. The agreement between predicted and measured values of UMP and line current is found to be good. The investigation leads to several new aspects of the damping effects of parallel stator windings and the cage rotor being highlighted.

<p> Of greatest interest in the field of linear motion electrical machines are, the flat linear induction motor and liquid metal pump. The former has feasibility in high speed transportation while the latter is becoming of increasing importance in metallurgical processes. </p> <p> This thesis examines and extends the traditional representation for the usual sheet secondary classification and then presents a common theory which also allows composite secondary machines to be analysed. An idealized model is developed consisting of a number of regions representing air gaps, iron segments, and secondary conductors. A general solution for the field quantities is obtained. The concept of wave impedance and a transfer matrix approach allow a wide variety of configurations to be analysed. Unlike previous work the approach developed here allows for simultaneous investigation of lateral variation and skin effect. In the limiting cases where in tum skin effect and lateral variation are neglected the solutions are in agreement with known results. </p> / Thesis / Master of Engineering (MEngr)

Master of Science / Department of Computing and Information Sciences / Torben Amtoft / An EFSM (Extended Finite State Machine) is a tuple (S, T, E, V) where S is a finite set of states, T is a finite set of transitions, E is a finite set of events, and V is a finite set of variables. Every transition t in T has a source state and a target state, both in S. There is a need to develop a GUI which aids in building such machines and simulating them so that a slicing algorithm can be implemented on such graphs. This was the main idea of Dr. Torben Amtoft, who has actually written the slicing algorithm and wanted this to be implemented in code. The project aims at implementing a GUI which is effective to simulate and build the graph with minimum user effort. Poor design often fails to attract users. So, the initial effort is to build a simple and effective GUI which serves the purpose of taking input from the user, building graphs and simulating it. The scope of this project is to build and implement an interface so that the users can do the following in an effective way:  Input a specification of an EFSM  Store and later retrieve EFSMs  Displaying an EFSM in a graphical form  Simulating the EFSM  Modify an EFSM  Implement the slicing algorithm All the above mentioned features must be integrated into the GUI and it should only fail if the input specification is wrong.
