The Computerised Design Of Prestressed Cncrete Slabs, Ronan Hogan
The Computerised Design Of Prestressed Cncrete Slabs, Ronan Hogan
Masters
This thesis was aimed at the development of a finite element based software package for the analysis and design of prestressed concrete slabs. Many of the existing packages used in this area carry out a simplified two dimensional analysis of the slab which does not account for the secondary stresses set up by the presence of openings and notches in the slab. In an attempt to overcome this particular weakness, a finite element analysis package was written to help produce a more rigorous analysis of the stresses developed in prestressed concrete. The aims of the research were the examination of …
Flexible Tools For Specifying Design Variation, Trichy Pasupathy, Xiaoping Zhao, Robert Wilhelm
Flexible Tools For Specifying Design Variation, Trichy Pasupathy, Xiaoping Zhao, Robert Wilhelm
Department of Mechanical and Materials Engineering: Faculty Publications
This paper describes flexible tools for specifying design variations that are based on nonuniform profile tolerance definitions. These tools specify bounds of design performance that can be used for negotiation among engineers in a collaborative design process. These specification methods allow for the capture of many different design functions that are not easily described with current tool designs. In addition, these specification methods lend themselves to efficient verification methods. Profile tolerance definitions provide the most general variation controls for complex mechanical surfaces. Common design practices and engineering standards for profile tolerances exhibit many weaknesses and limitations. We present a rationale …
Strategic Design Of Service Orientated Web-Based Supply Chain Infrastructure, Leone J. Dunn, Peter R. Gibson
Strategic Design Of Service Orientated Web-Based Supply Chain Infrastructure, Leone J. Dunn, Peter R. Gibson
Faculty of Engineering - Papers (Archive)
The traditional 'make and sell' attitude of industrial manufacturing organisations has now almost entirely given way to customer orientated 'sense and respond' service philosophies to the extent where this has become a major competitive key success factor in a global manufacturing industry. In order to become service orientated, manufacturing industry is increasingly dependent on efficient and effective supply relationships. This trend is compounded by needs for waste avoidance, minimal inventory, cost efficiency and appropriate service to the customer. This paper considers the strategic opportunities for large engineering project firms that have identified a need to establish advantages over their competitors …
A Robust Design Procedure For Improvement Of Quality Of Lower-Limb Prosthesis, Nian-Zhong Chen, Winson Lee, Ming Zhang
A Robust Design Procedure For Improvement Of Quality Of Lower-Limb Prosthesis, Nian-Zhong Chen, Winson Lee, Ming Zhang
Faculty of Engineering and Information Sciences - Papers: Part A
Lower-limb prostheses are used to restore amputee's walking. Monolimb is one of the designs referring to socket and the shank being molded into one piece of thermoplastic material. Appropriate shank flexibility of a monolimb can improve gait of an amputee. However, during the fabrication, the variations of design variables are inevitably produced which may lead the unexpected shank deflection and directly influence on gait efficiency of an amputee. This paper presents a robust design procedure for improvement of quality of the monolimb by simultaneously minimizing performance variations caused by variations in design variables and bringing the mean value of performance …
Systems Approach For Estimating Field Moisture Content, Thomas M. Petry, Yuh-Puu Han, David Newton Richardson
Systems Approach For Estimating Field Moisture Content, Thomas M. Petry, Yuh-Puu Han, David Newton Richardson
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
This paper describes a software tool developed for estimation of the field moisture content of subgrade materials. Subgrade behavior is directly related to its moisture content. Unfortunately, some approaches of estimating field moisture content are too complex to be used in routine design. In this paper, the authors attempt to provide an approach that is easy to use. The software presented here was developed using expert system approaches. It is capable of analyzing data entered by the users, and providing estimations to meet different scenarios. The information entered by the user is first examined for its reasonableness and accuracy. Then, …

Creativity: A Framework For The Design/Problem Solving Discourse In Technology Education, Theodore Lewis
Publications
Subjects for which aesthetics and creative performance are critical curricular dimensions (such as art, physical education, music, and technology education), and which are accommodative of students across the range of intelligences (Gardner, 1999) are not readily or completely captured by content standards. Therefore content knowledge in these fields that target student achievement as conventionally conceived must be complemented by treatment of more subjective and elusive goals such as the development of connoisseurship, appreciation, or creative insight. With the publication of standards for the subject (International Technology Education Association, 2000), the need for focus upon creativity in technology education has been …
Techniques In The Design Of Thermomechanical Microactuators, Larry L. Howell, Timothy W. Mclain, Michael S. Baker, Christian D. Lott
Techniques In The Design Of Thermomechanical Microactuators, Larry L. Howell, Timothy W. Mclain, Michael S. Baker, Christian D. Lott
Faculty Publications
The purpose of this chapter is to provide fundamental background for the design of thermomechanical microactuators. Actuation has been a particularly challenging aspect of microsystem development. Many actuation approaches used at the macro level, such as hydraulics, pneumatics, electric motors, internal combustion engines and turbines, are either too difficult to fabricate at the micro level or do not work well at that scale. Electrostatic attraction is one approach that has been widely used for actuation of microsystems; however, electrostatic actuators tend to have high voltage requirements and low output force capabilities. While electrostatic actuation is suitable for many applications, some …
