Equilibrium Conditions of Hydrate-Forming Pickering Emulsions
… and melting of the dispersed droplets. New phase equilibrium data of (cyclopentane hydrate + water 60:40) emulsions, in the concentration range from 0.1 to 2% of Span 80, is determined at atmospheric pressure (101.325 kPa). Requirements for thermodynamic validity of the equilibrium temperatures …

The Use of Driven Equilibrium Conditions in the Measurement of NMR Relaxation Times
… measurements often take. The DESPOT (Driven Equilibrium Single Pulse Observation of T1) method has been developed, which reduces the time required to make a T1 measurement by a factor of up to 100. The technique has been studied extensively herein and the thesis contains recommendations for …

Pore size distribution and methane equilibrium conditions at Walker Ridge Block 313, northern Gulf of Mexico
… hydrate systems. A discrete zone of three-phase equilibrium may occur near the base of the gas hydrate stability zone (GHSZ) in sediments with salinity close to seawater due to capillary effects. The existence of a three-phase zone affects the location of the bottom-simulating reflection (BSR) …

Optimization of Molecular Beacon-Based Multicomponent Probes for Analysis of Nucleic Acids
… differentiation range is in part due to the non-equilibrium hybridization conditions. Further we explored the idea that it is possible to improve the performance of an X sensor operable in close to equilibrium conditions by shifting its operability to non-equilibrium conditions. One way to …

Modeling and Control of Tensegrity-Membrane Systems
… systematic method is developed to determine the equilibrium conditions of general tensegrity-membrane systems. Equilibrium conditions can be simplified when the systems are in symmetric configurations. For one-stage symmetric systems, analytical equilibrium conditions can be determined. Three …

Nucleation and Growth of Calcium Carbonate and Sulfate Minerals from Solutions Close to Equilibrium
… carbon sequestration, past environmental conditions, the incorporation of radioactive and toxic metals, and the scaling of the desalination process. In this thesis, I investigated the nucleation and growth of calcium carbonate and sulfate minerals from solutions close to equilibrium which …

Solid state diffusion in Pd₂Si
… silicon is orders of magnitude higher than under equilibrium conditions. This is thought to suggest a vacancy mechanism of diffusion, and is expected that large numbers of vacancies are generated at the growth interface during silicide formation. Silicon self-diffusion in Pd₂Si has been …

Equilibrium systems : studies in masonry structure
… geometrical parameters and the possible equilibrium conditions. Collapse mechanism analyses are determined by combining kinematics and statics. Complex three-dimensional problems are analyzed using the same methods. This thesis presents a series of analysis tools that are fast and easy to …

Discrete Choice-based Equilibrium Modeling of Supply Chain Network with Conflicting Objectives and Demand Uncertainty
This PhD thesis discusses several equilibrium problems in supply chain network integration and specifically concentrates on the importance of collaboration under conflicting objective decision-making and uncertainty management in a supply chain network. In particular, discrete choice models are …

Market power and transportation price formation: Theory and an application to the captive shipper problem
… Measures developed from the market equilibrium conditions identify whether mill, uniform or discriminatory transportation pricing is the dominant type of price information. Other measures are derived which allow us to differentiate between price-setting and quantity-setting carrier …

Theoretical and Experimental Studies of Structure Formation in Polymer Solutions Under Flow
… in the absence of applied forces. Application of equilibrium conditions results in model predictions which are in good agreement with experimental observations i.e., changes in the binodal curve, increase in the amount of the separated concentrated phase and molecular weight fractionation with …

Non-equilibrium Green's function study of transport in disordered double-layer graphene systems
… graphene systems are investigated using the non-equilibrium Green's function (NEGF) formalism. The complexity of such a structure makes it imperative to study the effects of lattice vacancies which will inevitably arise during fabrication. Room-temperature performance characteristics for both …

The effect of various slag constituents on the distribution of phosphorus between slag and metal
… dephosphorizer was found to be only slight under equilibrium conditions. Magnesium oxide was found to be least effective in removing phosphorus for a given basicity ratio.

Alternative Methods for Determining the Expected Market Risk Premium: Theory and Evidence
… theoretical section of the study derives market equilibrium risk premiums among the three types of assets. Two hypotheses are proposed from the two market equilibrium conditions specified in the model. Empirical tests of the two hypotheses demonstrate a statistically significant risk premium …

Risk penalties for enhanced reliability in co-optimized markets with uncertain generation
… with risk-based objectives and the associated equilibrium conditions are given by a complementarity problem. Preliminary numerical results on a 6-firm problem provide insights regarding the impact of reserves and risk penalties on wind-based generation, particularly in the face of high …

Essays in industrial organization
… empirical impact of incomplete fee salience on equilibrium outcomes. Finally, I quantify the network externalities that must be present in order for observed fees to constitute an equilibrium. In the paper, I begin by developing a tractable model of the platform's problem that generates testable …

Roughness Effects on Super Structures in Turbulent Boundary Layer Flows
… small = −0.04, and favorable = −0.60 pressure conditions. It was observed that coherent structures larger than the field of view (FOV) modify their length scales, streamwise orientation and spanwise distribution in response to changes in surface roughness and pressure gradients. The study also …
