Identity, Conflict And Cooperation In International River Basins, Jack V. Kalpakian
Identity, Conflict And Cooperation In International River Basins, Jack V. Kalpakian
Graduate Program in International Studies Theses & Dissertations
This dissertation tests the hypothesis that water disputes cause serious conflict within and between states. It uses a structured case study approach to see whether there is a link between the independent and dependent variables. It also considers the effect of other variables on serious conflict. Specifically it addresses the effects of national identity and the othering process on conflict. The three case studies are built around rivers in the drier parts of the world. This biases the dissertation towards affirming the established mainstream hypothesis which states that water disputes cause serious conflict. In all three cases, historical animosities and …

Buckets: Smart Objects For Digital Libraries, Michael L. Nelson
Computer Science Theses & Dissertations
Discussion of digital libraries (DLs) is often dominated by the merits of various archives, repositories, search engines, search interfaces and database systems. While these technologies are necessary for information management, information content and information retrieval systems should progress on independent paths and each should make limited assumptions about the status or capabilities of the other. Information content is more important than the systems used for its storage and retrieval. Digital information should have the same long-term survivability prospects as traditional hardcopy information and should not be impacted by evolving search engine technologies or vendor vagaries in database management systems.

Wavelength Modulation Spectroscopy Of Water Vapor And Line Center Stabilization At 1.462 Μm For Lidar Applications, Colleen Marie Fitzgerald
Wavelength Modulation Spectroscopy Of Water Vapor And Line Center Stabilization At 1.462 Μm For Lidar Applications, Colleen Marie Fitzgerald
Electrical & Computer Engineering Theses & Dissertations
Wavelength modulation spectroscopy was employed to investigate water vapor absorption lines in the 1.462 µm wavelength region using an external-cavity diode laser. These measurements were necessary in the development of a lidar (light detection and ranging) instrument for differential absorption measurement of the concentration and movement of water vapor in the Earth's atmosphere. Differential absorption measurements require that the laser frequency remain stable throughout the duration of the measurement. To ensure this stability, the laser output wavelength is monitored and a feedback control loop set up to minimize laser line drift. Three lines were investigated in the 1.462 µm region. …
