D.Ed. / Currently, the passrate for Engineering Drawing presented at Technical Colleges is unacceptably low. This study is an extension of an earlier study done in the same studyfield, by the same writer. A need has thus arisen not only to investigate the problem areas responsible for the high drop-out rate in Engineering Drawing, but also to investigate the possibility of the early identification of the potential riskstudent in Engineering Drawing. In an attempt to address this problein further, the aim of this study therefore is to develop an appropriate measuring instrument which may be used to identify the potential riskstudent in Engineering Drawing. Five Technical Colleges on the Eastrand in the Gauteng Province - catering mainly for black students - were included in the investigation. For the research study the "Trade Aptitude Test Battery" (TRAT), compiled by the Human Sciences Research Counil, was used. The results of this study, clearly showed three-dimensional spatial perception (subtest 16 of the TRAT) as the only factor to be used when identifying the potential riskstudent in Engineering Drawing. Subtest 16 of the TRAT could then be used as an "criterion" to identify the potential riskstudent in Engineering Drawing. Lastly this study showed that to master Engineering Drawing requires a great deal of spatial ability. Lecturers presenting this subject will therefore have to take into account the recommendations of this study as set out in chapter 9 when enrolling students for Engineering Drawing. Subject specific remedial programmes should be utilized to improve the successrate in Engeneering Drawing of the identified potential riskstudent in Engineering Drawing.

M.Ed. (Curriculum Studies) / The future economic development of South Africa largely depends on the training of a career-skilled corps of workers. The current conventional educational system cannot provide in the demand for a career-skilled corps of workers on a large scale. Distance education in its different variations is gaining ground in increasing measure and can be regarded as a possible solution for the educational problem. Because of the distance between the lecturer and the student intensive attention needs to be given to the study material - especially the arrangement of the learning content to make the learning experience more effective. The design of a modular training program is a possible method to ensure effective self-study material. Modular training is aimed at accompa- nying the student meaningfully through objective-directed learning content. The Technical College of South Africa (Technisa) is one of South.Africa's distance education institutions. Currently a movement is taking place in the direction of a type of modular training which is known as the Technisa Modular Training (TMT) programme. One of the career-orientated subjects offered is Technical Drawing. In order to offer the training of Technical Drawing more effectively the subject contents are ordered according to the Technisa Modular Training programme. In this study a literature study has been done to define the concept distance education; to list the advantages and disadvantages; to scrutinise the total modular system as teaching strategy; to determine the components of a subject curriculum and adjust it according to the Technisa Modular Training programme.

The design of an efficient, low-cost system for automatically converting a hardcopy technical drawing into a highly compressed electronic representation is the motivation for this work. An improved method for extracting line and region information from a typical engineering drawing is presented. An efficient encoding method has also been proposed that takes advantage of the preprocessing done by the region and line extraction steps. Finally, a technique for creating a highly compressed mathematical representation (based on spline approximations) for the drawing is presented. / M.S.

A quantificação das pressões máximas e mínimas é de fundamental interesse para o projetista, a fim de que este possa dimensionar a tubulação e/ou prever dispositivos de proteção, cuja finalidade é amortecer as variações de carga, prejudiciais à vida útil da instalação. Neste trabalho optou-se pelo estudo de um destes dispositivos, o reservatório hidropneumático, que protege as instalações contra sobrepressões e subpressões, impedindo assim a descontinuidade do escoamento quando o sistema de bombeamento é desligado ou quando ocorre um fechamento rápido de válvula de bloqueio. O objetivo principal da presente pesquisa é o de formular tabelas e gráficos de aplicação para o pré-dimensionamento de reservatórios hidropneumáticos para a atenuação de transitórios hidráulicos em sistemas de condutos forçados, facilitando, desta maneira, o trabalho dos projetistas na escolha deste tipo de dispositivo de proteção de sistemas hidráulicos / Abstract: The evaluation of hydraulic transients is very important in the design of pipe networks. The determination of the maximum and minimum pressures is of great interest to the designer, so that he can size the pipes and/or design protection devices, with the objective of decrease head variations, that can decrease the instalation life. In this work, one of those devices was chosen for study, the air vessel, that protects the instalation against overpressures and underpressures, avoiding the interruption of the flow when the pumping system is turned off or when a valve closes too fast. The present work has the main objective of making charts and graphs of application for pre-sizing of air vessels to the mitigation of Waterhammer in pressure pipes by facilitating, in this way, the work of designers in choosing this type of protection of hydraulic systems / Mestrado / Recursos Hidricos / Mestre em Engenharia Civil

Approved for public release, distribution is unlimited / This thesis proposes a design for content repurposing of electrical diagrams for presentation in small-screen wireless handheld devices. Content repurposing is the on-line adaptation of content to fit device capabilities and user's preferences. The focus of this thesis is on electrical diagrams of the schematic type used for maintenance purposes. Nevertheless, many of the proposed techniques are suitable for other technical drawings as well. A significant amount of work has been done in summarization of Web documents and in diagram recognition, but not for presentation of diagrams in handheld devices. In the design proposed here, techniques are proposed for understanding the semantics of electrical diagrams and for partitioning the drawing images in intelligent ways to formulate coherent units for presentation to the user. / Lieutenant, Hellenic Navy
