The problem of detecting collisions between moving rigid objects in three dimensional space is considered. Two efficient algorithms that use linear programming techniques are developed for solving this problem. The algorithms can detect exactly all possible collisions for object…
Behavior-based robot control is a relatively new, but accepted, concept for building autonomous robots. Several different kinds of proof-of-concept robots using the so-called subsumption architecture have been demonstrated. These robots have been shown to solve some fairly diffi…
In this thesis, a telerobotic system has been designed, to allow remote control of a robot arm existing in the college of computer science and engineering laboratories, over the college network and by using a master arm that has been built locally. The system is developed for si…
The Citarum River basin in West Java, Indonesia, has a cascade of three reservoirs, Saguling Reservoir, Cirata Reservoir, and Juanda Reservoir, linked in series from upstream to downstream. Cirata and Saguling Reservoirs function primarily for hydroelectric power production, whi…
Production, quality and maintenance are three important aspects in any industrial process. Many attempts have been made in the literature to develop models which integrate them. However, these aspects have been generally treated separately. This thesis presents three integrated …
A number of alternatives were considered to keep pecan processing economically competitive and sustainable. The industry needed a low risk evaluation technique for testing new high capital plant configurations. A simulation model was developed using the AweSimTM simulation syste…
In this thesis a systematic scheme is proposed to design fuzzy optimal controllers. The proposed scheme adjusts the parameters of the fuzzy controller using a gradient descent scheme in order to optimize a chosen performance criterion. The optimization is carried out employing a…
This study was to evaluate the development level of Clinical Engineering Departments (CEDs) in hospitals in developing countries. The method of data collection was a survey done by structured questionnaire sent by Email and Listserv. In total, 61 responses (9% response rate) wer…
Variable Structure Control (VSC) with sliding mode is a special type of control technique that is capable of making a control system robust with respect to system parameter variations and external disturbances. The chattering of the VSC signal can be reduced by several methods. …
Effective decision making in public and private enterprises stems fundamentally from understanding the dynamic complexity of evolutionary social, political, and managerial systems. At the heart of learning about dynamic systems lies the telling of a sound and cogent story about …
Resources available for the completion of each activity of a project (represented as an activity network) are always limited in the real life and so, finding the optimal schedule for the activities is very hard. Such a problem is termed as Resources-Constrained Project Schedulin…
This study assessed the complex problem of government intervention in promoting technological innovation in Indonesia. The severity of international competition and the dynamic changes in the economies and technologies of nations have made national innovation policies necessary …
An internship experience on the implementation of a manufacturing resources planning (MRP II)-type software system at a large wire and cable manufacturing company is reviewed. The MRP II system installed at the Saudi Cable Company (SCC) at Jeddah, Saudi Arabia, had not been comp…
A systems approach for solving problems of process control engineers in process diagnostics, graphics and computational power is applied here. A popular microcomputer is used to develop an interactive but powerful process identification package. Stochastic time series analysis m…
This research is concerned with presenting a method to deal with Skolem functions (intensional entities) in first-order data bases. An example of a situation in which these functions have to be used is when we want to express the fact that everyone has a mother. In logical form,…
Development of an expert system, called FAX, to address the following problems is reported: (1) determination of the root causes of process malfunctions; (2) execution or suggestions for corrective action(s) to cope with the abnormal process situation. A hierarchical system deco…
A speaker-independent Arabic digits recognition system is implemented which uses template matching of input utterances with a stored set of multiple templates for each digit. The system is based on the LPC parameters for features, the log likelihood ratio for a distance function…
In this thesis, the problem of recognizing a speaker from noisy speech has been studied. Sambur's algorithm that utilizes orthogonal linear predictive coding (OLPC) parameters is chosen for this study because of its simplicity and high recognition accuracy. The effect of noise o…
