Radar - A Novel Admission Control And Handoff Management Scheme For Multimedia Leo Satellite Networks, Syed Rashidali Rizvi Dec 2005

Radar - A Novel Admission Control And Handoff Management Scheme For Multimedia Leo Satellite Networks, Syed Rashidali Rizvi

Computer Science Theses & Dissertations

Low Earth Orbit (LEO) satellite networks are deployed as an enhancement to terrestrial wireless networks in order to provide broadband services to users regardless of their location. In addition to global coverage, these satellite systems support communications with hand-held devices and offer low cost-per-minute access cost, making them promising platforms for Personal Communication Services (PCS). LEO satellites are expected to support multimedia traffic and to provide their users with some form of Quality of Service (QoS) guarantees. However, the limited bandwidth of the satellite channel, satellite rotation around the Earth and mobility of end-users makes QoS provisioning and mobility management …


Quantifying Vulnerability To Critical Infrastructure, Barry Charles Ezell Apr 2005

Quantifying Vulnerability To Critical Infrastructure, Barry Charles Ezell

Engineering Management & Systems Engineering Theses & Dissertations

Military and civilian leaders have the responsibility to protect our Nation's critical infrastructure, communities, and symbols of American power from terrorists, home and abroad, as well as from natural disasters. To this end, assessments are conducted to reduce vulnerability. The literature offers multiple definitions of vulnerability and measurement has not been adequately addressed. Thus, the purpose of this research has been to develop and deploy a systems-based model that quantifies vulnerability to critical infrastructure. This research defines critical infrastructure vulnerability as a measure of the susceptibility of critical infrastructure to threat scenarios. Vulnerability is a function of (1) threat scenario, …


Multi-National Project Team Communications And Cultural Influences, Morgan E. Henrie Jan 2005

Multi-National Project Team Communications And Cultural Influences, Morgan E. Henrie

Engineering Management & Systems Engineering Theses & Dissertations

This exploratory case study dissertation examined multinational project teams' communication satisfaction as influenced by the project team's cultural attribute of power distance. Utilizing a exploratory case study, semi-guided interview research approach, ordinal scale data and open-ended contextual based question responses was obtained. This data was gathered from United States---Russia and Canada---Angola multi-national, complex, high technology oil transportation project teams. Triangulation data gathering techniques were utilized to obtain empirical data from multiple sources of data and multiple data types. Subsequent data analyses combined descriptive statistical analysis, graphical analysis, cluster analysis, and content analysis techniques to derive a theoretical construct of multi-national …
