BASICS for the teaching and learning of technical drawing at secondary school level. A modular approach was adopted using the computer as medium of instruction programs arranged T.D BASICS is an individualized in sequential learning form of order and broken down into small tasks or activities for the leaner to progress at his or her own rate. The Technical drawing software package is divided into two lessons. Lesson one: Technical Drawing Basics. Lesson two; Geometry Lesson one presents a check list of what a student of technical drawing should learn for effective drawing. These are;- Uses and care of drawing instruments, lines and lettering techniques, board practice, freehand sketching, dimensioning and notation. Lesson two presents in detail the technique associated with geometric in constructions. It covers both the plane and solid geometry. Each lesson is divided into a number of modules programmed in a logical step by step order from simple to complex for use at all levels of the secondary school educational setting (JSS I- SSS3). The objectives for each module are outlined at the beginning to give an insight into the expected learning outcome. Questions are equally provided at the end of each module for student evaluation. The software was developed with visual basic programming language. T.D BASICS was found to be useful in the teaching and learning of technical drawing and as a self-educator. The application software is fully interactive and user friendly. It runs on Microsoft windows operating system. ix, 351p. : ill. ; 30cm Thu, 01 Jun 2006 00:00:00 GMT http://196.220.128.81:8080/xmlui/handle/123456789/5887 2006-06-01T00:00:00Z http://196.220.128.81:8080/xmlui/handle/123456789/5884 DEVELOPMENT OF COMPUTER-AIDED DESIGN SOFTWARE FOR JIGS AND FIXTURES FOR DRILLING FLANGES ABIODUN, ODUFALE OLATUNDE A detailed review of relevant literature was carried out to provide basic information on the construction of jigs design. Also, the documentation of acquired data for the purpose of developing suitable design process using Computer Aided Design (CAD) was carried out. A computer software that would automatically draw the needed jigs and fixtures from the data or the flange (object) was developed. A description of the design requirements and constraints was obtained by considering the different configurations of the workpiece. A geometric model of the fixture was developed and analysed for kinematic, force and deformation compatibility. A heuristin algorithm was developed and the program written using JAVA language default package. The program is user-friendly and was written in modules to allow for flexibility and quick responsiveness. The program was validated with real life sample data from a workpiece. xvi, 126p. : ill. ; 30cm Fri, 01 Sep 2006 00:00:00 GMT http://196.220.128.81:8080/xmlui/handle/123456789/5884 2006-09-01T00:00:00Z http://196.220.128.81:8080/xmlui/handle/123456789/5883 DEVELOPMENT OF AN INDIGENOUS, BENCH-TOP MANUAL TORSION TESTING MACHINE GHAZALI, AKEEM The increasing enrollment of students in higher institutions of learning in Nigeria demands higher capital expenditures, which either in some cases are not available or grossly insufficient, to provide essential machines and equipment for the training of professional engineers and technologists. Consequently, torsion test is often overlooked despite its importance in the investigation of mechanical properties for automobile, manufacturing, and bio-medical engineering products. An indigenous bench-top manual torsion testing machine was developed to perform pure torsion test on metal rods. The machine provided information on the shear properties of the materials being tested upon which shear moduli were determined. The machine was produced predominantly by fabrication method coupled with machining and casting processes. The various materials of production included mild-steel, aluminium, cast-iron, tool-steel, and polymer. Torsion test was conducted, using the machine so developed in this work, on Aluminium and Brass specimen with 5 mm diameter, respectively; and 5.5 mm diameter of Mild-steel. The experimental shear moduli from the test shown that Aluminum has 23,205.92 N/mm2 (16% less than expected), while Brass has 21,498.06 N/mm2, (43% less than expected) and Mild-steel has 15,773.10 N/mm2(80% less than expected). The results suggested a re-investigation into the load measuring unit, as the applied torque load may be higher than the one being measured. However, a simple practical approach is being made to demonstrate torsion test for teaching purposes. xiii, 69p. : ill. ; 30cm Wed, 01 Dec 2010 00:00:00 GMT http://196.220.128.81:8080/xmlui/handle/123456789/5883 2010-12-01T00:00:00Z http://196.220.128.81:8080/xmlui/handle/123456789/5882 DEVELOPMENT OF AN EMPIRICAL MODEL FOR JOBSHOP FLOW TIME AND DUE-DATE PREDICTION AKINNULI, OLUFEMI BASIL A computer software was developed and tested for validation for jobshop flowtime and due date prediction. The software utilises data from shop floor which are analysed to predict expected waiting time on each individual machine on a periodic bases. Projection of these waiting times are made for future flow time prediction by using moving averages. The methodology employed implicitly accommodates job characteristics, shop status, system characteristic as well as delaying factors external to the shop. This software is capable of prescribing a range of due-dates to reflect the best, most likely and worst case possible scenarios with their times. When the total theoretical time of a job was 570 minutes, with the arrival date and time 24/08/98 and 8:00 hours respectively the software was able to predict the due-dates for best case scenario, most likely scenario and worst case scenario thus: Best case Scenario due-date: 24/08/98 Time: 12:08 hours Most likely Scenario due-date: 25/08/98 Time: 12:08 hours Worst case Scenario due-date: 26/08/98 Time: 13:08 hours This range will greatly assist management in negotiations with prospective customers. Improving performance of job shops and their ability to execute jobs within due-dates. x, 135p. : ill. ;30cm Sat, 01 Aug 1998 00:00:00 GMT http://196.220.128.81:8080/xmlui/handle/123456789/5882 1998-08-01T00:00:00Z
