Technology Acceptance: A Fusion Of Human-Computer Interaction And Management Information Systems Constructs, Patrick W. Wright
Technology Acceptance: A Fusion Of Human-Computer Interaction And Management Information Systems Constructs, Patrick W. Wright
Theses and Dissertations
In recent years, information technology has advanced at a pace that few would have anticipated. It has been estimated that the computing power of the modem desktop computer has been increasing at the rate of 1000% per decade. In combination with the development of personal computers, the advent of networks and the world wide web provide unprecedented access to information and computing power. However, the problem of developing useful user interfaces remains a problem. In many military and commercial settings, the increased computing power offered by current information technology remains unexploited because of user interfaces that are difficult to use. …
Media Selection In The Air Force Environment: How Communications Requirements Influence Effectiveness As An Outcome Of Media Choice, David L. Hillman
Media Selection In The Air Force Environment: How Communications Requirements Influence Effectiveness As An Outcome Of Media Choice, David L. Hillman
Theses and Dissertations
Over the past two decades, great interest has been given to the research of media choice within organizations. However, there is still confusion over which factors influence media choice. This study examined the effectiveness of five media under different conditions in an effort to better understand which factors impact media choice. Through the examination of several theories on communication and media choice, a theoretical model was created to determine if effectiveness is an outcome of media choice. To test the proposed model, a 54 scenario policy capturing instrument was developed and distributed. Results from the study support the theory that …
Optimizing The Efficiency Of A Multi-Stage Axial-Flow Compressor: An Application Of Stage-Wise Optimization, Shawn A. Miller
Optimizing The Efficiency Of A Multi-Stage Axial-Flow Compressor: An Application Of Stage-Wise Optimization, Shawn A. Miller
Theses and Dissertations
The development of jet engines has become an integral part of maintaining air superiority. In order to achieve the most advanced engine, research has turned to traditional optimization methods to aid in creating new engine designs. To develop simplified mathematical models representative of the engine, the engine can be separated into its components. A jet engine has three major elements, the compressor, combustion chamber and turbine. This research attempts to make an initial analysis of a two stage compressor to determine values of blade angles and spacing to chord ratios for both stages that produce the highest possible efficiency for …
