Influence Of Turning On Military Vehicle Induced Rut Formation, Kun Liu
Influence Of Turning On Military Vehicle Induced Rut Formation, Kun Liu
Doctoral Dissertations
Rut formation can severely influence soil conditions and vegetation, and reduce vehicle mobility. Vehicle operations can affect rut formation. Ruts formed in straight vehicle paths are different than when the vehicle turns. This research is mainly to investigate the effects of vehicle turning maneuvers on soil rut formation, including field tests, lab tests, and model development.
Field tests were conducted at Yuma Training Center, Fort Riley and Fort Lewis on wheeled and tracked military vehicles. In field tests, rut depth, rut width and rut index were used as the main indicators to quantify a rut. A Vehicle Tracking System was …
A Condition Assessment Process For Aerospace Ground Test Systems, Larry Michael Davis
A Condition Assessment Process For Aerospace Ground Test Systems, Larry Michael Davis
Masters Theses
This research developed a process to identify condition deficiencies and sustainment requirements to assist in the development of strategic management plans for aerospace ground test systems that may be unique in design, operation, and/or maintenance.
Subject matter experts can use the process to evaluate the condition of a test asset by inputting data into the developed software system. The process was designed around the concept of evaluating the condition of a system against ten parameters that encompass all of the aspects of a system that would be considered in determining its overall condition. A scale of zero (failed) to ten …
A Business Process Modeling Approach For Evaluating A Government Contract Closeout Process, Clayton Jerrett Capizzi
A Business Process Modeling Approach For Evaluating A Government Contract Closeout Process, Clayton Jerrett Capizzi
Masters Theses
This thesis examines the practice of Business Process Modeling (BPM) in the field of contracts management. Government defense contractors are heavily burdened by contracts which have ended, but have not been finalized and closed. In order to keep good relations with organizations regulating government contracts, contractors have been forced to devise a strategy to address contract closeouts. Through utilization of BPM practices, an organization is able to not only model the flow of their contract closeout process, but simulate the performance of their process under varying conditions so that goals and deadlines may be met. Data was collected about a …
Scheduling For Service Stability And Supply Chain Coordination, Yuerong Chen
Scheduling For Service Stability And Supply Chain Coordination, Yuerong Chen
Doctoral Dissertations
This dissertation studies scheduling for service stability and for supply chain coordination as well. The scheduling problems for service stability are studied from the single perspective of a firm itself, while the scheduling problems for supply chain coordination are investigated from the perspective of a supply chain. Both the studies have broad applications in real life.
In the first study, several job scheduling problems are addressed, with the measure of performance being job completion time variance (CTV). CTV minimization is used to represent service stability, since it means that jobs are completed in a relative concentrated period of time. CTV …
Qos Provision For Wireless Sensor Networks, Dengfeng Yang
Qos Provision For Wireless Sensor Networks, Dengfeng Yang
Doctoral Dissertations
Wireless sensor network is a fast growing area of research, receiving attention not only within the computer science and electrical engineering communities, but also in relation to network optimization, scheduling, risk and reliability analysis within industrial and system engineering. The availability of micro-sensors and low-power wireless communications will enable the deployment of densely distributed sensor/actuator networks. And an integration of such system plays critical roles in many facets of human life ranging from intelligent assistants in hospitals to manufacturing process, to rescue agents in large scale disaster response, to sensor networks tracking environment phenomena, and others.
The sensor nodes will …
