The major purpose of the study was to develop simulation materials uniquely designed for use in preparation programs for secondary school administrators in Indiana. The procedures used in the study included the following: (1) development of a conceptual framework for guiding the construction of simulation materials, (2) development of background materials describing the simulated school system, (3) development of selected administrative problems for use with the simulated school system, (4) development of a format and a procedural guide for use of the simulation materials in a class in secondary school administration, (5) use of the simulated materials and selected administrative problems in a pre-service secondary school administration class, (6) preparation of an evaluation instrument to secure student evaluations of simulation materials and techniques, (7) administration of the evaluation instrument, (8) analysis, tabulation, and presentation of the data obtained through administration of the evaluation instrument, (9) presentation of the findings, conclusions, and recommendations for further study, and (10) presentation of the simulation materials, decision analysis form, and questionnaire used in the study. Student evaluations pertained to the following aspects of student perceptions of the simulation materials and utilization procedures developed as a part of the study: (1) the "reality" of the simulation experiences, (2) the orientation value of the in-basket problems, (3) the value of the simulation materials for creating an understanding of the need for additional professional preparation, (4) the orientation value of the background materials, (5) the value of the simulation activities, (6) the relative value of simulation as a teaching technique, (7) the most-valued and the least-valued in-basket problems, (8) the adequacy of time allocations, (9) suggestions for improvement of the simulation materials and activities, (10) suggestions for additional uses of simulation materials, and (11) the most-liked and the most-disliked aspects of the simulation experiences. Conclusions were based upon the findings of the study, on the literature and research reviewed as a part of the study, and on the experiences of the writer in designing and testing the simulation materials developed as a part of the study. 1. The simulated in-basket problems have potential value for orienting pre-service secondary school administrators to current problems of practicing secondary school administrators in the State of Indiana. 2. The simulation materials have limited potential value for creating an understanding of the need for additional professional preparation prior to assuming the secondary school principalship. 3. Utilization of the background materials as reference sources for the in-basket problems has potential value for orienting students to the contents of legal, procedural, and regulatory reference materials commonly used by practicing secondary school administrators in Indiana. 4. Both pre-service and in-service educational administrators enthusiastically support the use of stimulation materials as an instructional device. Students using simulation materials readily become involved in simulation activities and do perceive such activities as being of considerable instructional value. 5. Educational administration students do perceive simulated administrative problems as representing authentic problems of practicing school administrators. 6. Individual and group problem-solving simulation activities do induce educational administration students to develop alternative strategies for problem solutions. 7. Simulation materials and utilization procedures representing authentic educational administration problems, which will be perceived as moderately realistic administrative experiences by students using such materials, can be inexpensively developed and tested. Recommendations for further study were based upon the findings of the study, upon the literature and research reviewed as a part of the study, and upon the experiences of the writer in designing and testing the simulation materials. 1. The simulation materials developed as a part of the study should be used with other pre-service secondary school administration students in other institutions of higher learning in Indiana for the purpose of validating or rejecting the findings of the study. 2. Studies should be initiated for the purpose of comparing performance of simulated administrative tasks with on-the-job administrative performance. 3. The feasibility of presenting the simulated administrative problems developed as a part of the study through media other than the in-basket medium should be investigated.

This thesis deals with the application of modern identification techniques to model the dynamic relationship between the fuel flow and shaft speeds of a Rolls Royce aircraft gas turbine. It is motivated by the desire to exploit recent advances in modelling linear and nonlinear systems and the need to investigate the suitability of various model representations in nonlinear gas turbine modelling. The first part of the thesis deals with linear gas turbine modelling, with the aim of estimating models which can be used to verify the linearised thermodynamic models derived from the engine physics, at different shaft speeds. A detailed analysis of the engine data is presented and linear engine models are identified at different operating points using time- and frequency-domain techniques. The influence of noise and nonlinearities on the estimated models is studied and it is shown that the use of multisine signals and frequency-domain techniques is particularly suited to this problem, since the derived continuous-time s-domain models can be directly compared with the linearised thermodynamic models. It is also shown that discrete models estimated in the time domain have excellent approximation capabilities but are not suited for the validation of the thermodynamic models since their modes are uncertain and they sometimes result in modes which do not have a continuous-time counterpart. The second part of the thesis deals with the application of several nonlinear system representations to model the nonlinear relationship between the fuel flow and shaft speeds of the gas turbine. Data is analysed in both time- and frequency-domain to gain information about the engine nonlinearity, and several nonlinear model representations are presented along with popular estimation algorithms. Nonlinear models for each shaft were then estimated and the performance of these models was demonstrated by their ability to approximate measured engine data. It is shown that the nonlinear relationship between the fuel flow and shaft speed can be modelled using a Wiener structure, a NARMAX structure or a neural network. Several issues concerning signal design and prior knowledge of the nonlinearity in a system are also discussed and a number of recommendations are made for future gas turbine modelling and testing. This thesis is a contribution to the further application of multifrequency signals and time- and frequency-domain techniques to the identification of linear and nonlinear models for aircraft gas turbines. While this work was applied to a gas turbine, these techniques can be applied to a range of industrial applications that deal with system testing and modelling.
