In this paper, a computer program was developed in MATLAB programming language and applied in the refurbishment of defective three-phase squirrel-cage induction motor using the computer-aided design technique/approach. The MATLAB programming language and Computer-Aided Design (CAD) analysis adopted aided the fast computation and convergence of a output result from the developed program that was used in the practical refurbishment of a defective 48-slot 3-phase squirrel-cage induction motor as well as the production of the entire stator winding. The result also revealed the motor as being a 4-pole type which lends itself easily to the lap winding pattern. The winding was practically developed using the program result data, installed, connected and tested. The speed realized from the post-refurbishment workshop test-running using the stroboscopic speed measuring instrument was 1500rpm. This was considered as good performance on no-load condition. The machine was allowed to run for about one hour during the workshop test-running without overheating. The computed output power was 20 kW. The estimated efficiency and power factor by CAD technique were 90 % and 0.9, respectively. These values were considered satisfactory.

The concerns of comfortable seat grew more momentous as this era brought new technologies leading to nonstop flights and more dependence on computers; hence, individuals spend more time seated to perform everyday activities. Uncomfortable prolonged sitting may reduce the quality of such activities and may yield health implications. Seat comfort evaluations are conventionally done post-production i.e. a fully produced seat is usually required in order to evaluate its level of comfort. Also, the inputs from the customer which could have significant impression on the comfort level of the seat are usually not considered during the design stages. This study proposes a solution with a system that performs seat comfort design and evaluation by integrating a Quality Function Deployment (QFD) tool with Computer Aided Design (CAD) technique. Several laboratory tests were performed to validate the proposed technique and the obtained results verify that the system can be a valid tool that can surrogate the traditional techniques for comfort analyses. The proposed system offers a comprehensive and systematic tool for the design and prediction of seat comfort by integrating the voice of the customer via QFD into CAD. Taking everything into account, the proposed system will diminish the need for physical prototyping, limit the involvement of human subjects and facilitate information sharing.

This paper provides a design technique of support for being applied in fast fabrication on plastic prototype, the plastic part developed through the computer aided design (CAD) can be rapidly fabricated by a CNC machining center without needs of any specific jigs or fixtures, the function provided is similar to a rapid prototyping (RP) machine used for fabricating the sampling part. By the testing result, the provided design technique of support can not only be applied in the part required for a dual-surface (or multiple-surface) processing, but also applicable for fabricating the part having thin housing. As such, this paper provides another economical and efficient option besides the RP.

This paper aims through several numerical studies to highlight some effects of layering plates in ballistic protection. The possible increase in perforation resistance by varying the material properties of the plates, the individual plate thickness (the total plate thickness is constant) and the stacking of individual plates in a double-layered target when struck by blunt and ogival nose projectiles has been investigated. This was done by conducting non-linear finite element simulations of the perforation process using an experimentally validated numerical model and an explicit finite element code. These studies are difficult to carry out experimentally due to the many materials and thicknesses involved and computer-aided design is thus an attractive approach. The numerical design indicates that it is possible to considerably increase the overall ballistic protection level by using double-layered plates and a proper design. Some of the most promising designs were then selected for experimental validation. The experimental tests gave completely opposite results than the computer-aided design, and the reasons for this will be discussed in some detail.
