Engineer Education: Disciplinary Preferences In The Faculty Of Engineering University Of Dar Es Salaam, S Mosha

Tanzania Journal of Engineering and Technology (TJET)

Most practising engineers can hardly recall the days they had to make up their minds on whether engineering was their chosen career. This decision may have been approached with ignorance and very high expectations. Later after registering in a Faculty of Engineering the freshman was given a chance to choose a department; sometimes this had already been done for him by his sponsors so all he had to do was to walk into the preselected department.

A generation later, University entrants are faced with a similar predicament. This paper high-lights the procedures involved and proceeds to recommend the necessary fundamental …

Investigation Of Mental Workload In A Visual Inspection Task, Michel Alfandari

Theses

This thesis consists of an investigation of the "mental workload" involved in a visual inspection task. A short-term laboratory experiment was conducted on twenty test subjects to study the effects of three typical job-related factors encountered in mental workload situations: load stress, time stress, and motivation. These effects were assessed through the subjects' performances as measured by speed and accuracy data. The analysis of the results revealed that an increase in load stress deteriorates both speed and accuracy, whereas time stress improves speed but only at the expense of accuracy. The expected positive influence of motivational factor (cash prizes) was …

A Monte Carlo Approach To Ridge Discriminant Analysis, Lee Wooldridge

Retrospective Theses and Dissertations

A combined analytical and empirical method to define human performance measures is required for effective automated training. In theory, performance measures can be weighted and combined in a single first order equation upon which an automated training system can track a student's comparative skill level. A form of multivariate discriminant analysis was the statistical technique incorporated into the measurement selection and weighting scheme. (Vreuls and Wooldridge 1977). As with regression analysis, this discriminant technique was subject to debilitating problems such as overfit and undesirable inaccuracies in the coefficients. The author developed and implemented an adjustment to the discriminant function analogous …

Point Of Operation Safeguarding - A Metal Forming System Approach, William Baker Eaton

Theses

The mechanical power press in its application in the metal stamping and forming industry has been misinterpreted as a selfcontained metal forming system. Examination of the production routines involving the press show that this machine is actually only one elemental component of the metal forming system and not the total production unit.

Authoritative codes and standards pertinent to the mechanical power press have reflected this misinterpretation by not including system considerations in their contents. These omissions have resulted in the providing of safeguards which do not properly reflect the particular characteristics of the metal forming system to which they are …

Production Attachment For Wood Turning, Julian A. Olson

Graduate Research Papers

As an industrial arts instructor for the short period of three years the writer has recognized a definite shortcoming in his instruction of the woodworking lathe. Instruction related to the woodworking lathe by the conventional "hand tool" methods is most important in leading to the students' understanding of basic turning ideas. This instruction, however, falls short of providing an up-to-date picture of the woodworking lathes used by industry.

As a means of overcoming this problem, the writer undertook the study of lathes as a project for the course, "Projects in Industrial Arts". This research provided information necessary in the construction …

Plastics: Mold Design And Fabrication, Duane H. Rippe

Graduate Research Papers

Students have often asked if additional molds were available which would make different objects other than golf tees. Literature provided with the injection molder described several methods of mold construction which could be fabricated in the school shop. The writer considered the possibility of making another mold, however, a time factor and limited experience prohibited construction.

The problem seemed to be appropriate for the Projects Course 33:270 at the University of Northern Iowa. The course and research involved would assimilate the needed information to construct a mold and to teach plastic injection mold construction more effectively.
