• #### Experimental investigation of crust-mantle hybridization in the Earth’s shallow upper mantle ﻿

(2014-11-13)
Chemical heterogeneities in the Earth’s mantle, such as subducted sediments and oceanic crust, along with volatiles such as H2O and CO2 affect melting processes, hence, chemical differentiation of the Earth and their ...
• #### Experimental observation of the photon structure function at 21 GeV ﻿

(1998)
The triggered photon structure function at center-of-mass energy 21 GeV is measured from the interaction $\gamma$p $\to$ jets. Descriptions of the experimental apparatuses are given and the physics goals of the experiment ...
• #### Experimental results and three-dimensional simulations of instabilities in a rotating lid-driven cylinder ﻿

(2012)
An experimental setup for a rotating lid-driven cylinder problem is designed and constructed in the context of modeling bulk semiconductor crystal growth techniques. Details concerning construction of the experimental setup ...
• #### Experimental setup for the operation of gas electron multipliers in liquid-gas xenon detectors ﻿

(2004)
A setup for the realization of dual-phase experiments using xenon as the active medium in a radiation detector has been built. The setup consists of a gas purification system capable of achieving a purity of the gas in the ...
• #### EXPERIMENTAL SIMULATION OF THERMAL MATURATION IN SEDIMENTARY ORGANIC MATTER. (VOLUMES I AND II) ﻿

(1981)
This study simulates thermal maturation of liptinitic and humic organic matter (Phosphoria shale and Rattlesnake Butte lignite) by isothermal pyrolysis at temperatures of 230(DEGREES), 275(DEGREES) and 325(DEGREES)C for ...
• #### Experimental studies of nucleate pool boiling from artificial active sites ﻿

(1963)
Artificial active sites were studied during nucleate pool boiling of degassed carbon tetrachloride. The pressure of the system was controlled a t one and also at one and one-half atmospheres. Dynamic two phase behavior ...

• #### Experimental studies of the fractional quantum Hall effect and the Wigner solids ﻿

(2010)
This Ph.D. thesis is composed of two parts: the first part is concerned with electron transport in the higher Landau levels (LL) in a two-dimensional electron system (2DES); the second part is focused on the Wigner Crystal ...
• #### Experimental study of (He_,d) and (He_,t) reactions on Be_ and B__ ﻿

(1966)
The reactions Be9(He3,d)B110, Be9(He3, t)B9, B11(He3d )C12, and B11(He3, t )C11 were studied using a doubly ionized 10 MeV He3 beam. Particles were detected in a Delta E, E solid state counter telescope. The Delta E and E ...
• #### Experimental study of heat transfer to hypersonic nozzle walls ﻿

(1963)
The heat transfer rate from a high enthalpy gas to the walls of a diverging nozzle, through which the gas was flowing, has been experimentally determined. The experimental results are compared with the predictions of several ...

(1978)
• #### Experimental Study of Potassium and Strontium Rydberg Atoms - Chaotic Ionization, Quantum Optical Phenomena and Multiphoton Excitation ﻿

(2014-04-24)
Very-high-n (n~300) Rydberg atoms serve as a powerful tool to study chaos and quantum optical phenomena. Measurements using a series of alternating impulsive kicks applied to potassium Rydberg atoms reveal that a phase ...

• #### Experimental study of the degree of ionization of a partially ionized gas flowing in a hypersonic nozzle ﻿

(1963)
The primary objective of this work was to experimentally determine the degree of ionization in a partially ionized gas flowing in a converging-diverging nozzle. Stagnation point Langmuir probes were employed for this ...
• #### Experimental study of the effect of commercial dispersants on the precipitation, aggregation and deposition of asphaltenes ﻿

(2015-11-30)
Asphaltene precipitation and subsequent deposition is a potential flow assurance problem for the oil industry nowadays. Moreover, because oil production is moving to more difficult production environments – e.g. deeper ...
• #### Experimental system identification of model frames using frequency-domain and time-domain methods ﻿

(1994)
Two different metal test frames are excited using the impact-hammer method. The force-input and specific acceleration-output time-histories were recorded, and through frequency-domain, and time-domain structural system ...
• #### Experimental test of the effects of supportive breeding on wild populations ﻿

(2008)
Supportive breeding is currently being used in the management of threatened populations, but the effects of this management strategy remain relatively untested. The common house fly, Musca domestica, was used as a model ...
• #### Experimental/analytical approaches to modeling, calibrating and optimizing shaking table dynamics for structural dynamic applications ﻿
