Development Of Holographic Recording Techniques For Optical Couplers Designed For Solar Collection From Windows, Dipanjan Chakraborty

Doctoral

The main purpose of this research is to explore volume holographic optical couplers and investigate their potential for use as solar collectors in glass building structures. Such couplers are from the family of volume holographic optical elements (VHOEs) and their primary function is to re-direct the incident light so that it is trapped by Total Internal Reflection (TIR). They have been proposed for different waveguiding applications such as solar collection, head-up displays, and optical communication. Since the Sun is a non-stationary light source, often at a high altitude, couplers designed for non-normal incidence are crucial.

Ultimately, this work will address …

Active Listening And Reassurance In Text-Based Virtual Health Coaches, Ghulam Hussain

Dissertations

The Territorial Continuum: American Samoa, Criminal Adjudication, And Territorial Administration, Emmanuel Hiram Arnaud

Faculty Scholarship

The standard account of American territorial expansion posits that territorial acquisition moved along a spectrum of sovereignty. The federal government acquired new inhabited land through conquest or purchase, and the Constitution tasked Congress with organizing and administering the new territories until they were ready to become states. That pattern came to an abrupt halt in 1898 when, at the conclusion of the Spanish-American War, the Supreme Court, fearing the extension of citizenship to, and the permanent integration of, non-White populations into the American polity, suddenly pronounced that the Constitution authorized the holding of colonies. The Court thus sentenced new territories, …
