Effects of dynamic shear stress on endothelial cells, platelets and their interactions
(2013-05)
Coronary heart disease (CHD), characterized by degenerative changes in coronary circulation, is the leading cause of death in the US. Vascular wall endothelial cells (EC) and circulating blood platelets play a major role ...
Thermal performance of mechanical pipe insulation systems at below-ambient temperature
(2013-12)
Mechanical pipe insulation systems are commonly applied to cold piping surfaces in most industrial and commercial buildings in order to limit the heat losses and prevent water vapor condensation on the pipe exterior surfaces. ...
Modeling, analysis and control of print registration in roll-to-roll printing presses
(2013-05)
Print registration in roll-to-roll (R2R) printing process is investigated in this dissertation. Print registration is the process of aligning multiple images that are printed in consecutive print units. The quality of the ...
Modeling and control of web transport in the presence of non-ideal rollers
(2013-05)
In roll-to-roll processes the presence of non-ideal elements, such us out-of-round or eccentric rollers is fairly common. Periodic oscillations in web tension and web velocity are observed because of the presence of such ...
Estimations of undisturbed ground temperatures using numerical and analytical modeling
(2014-12)
The interaction of buildings and ground source heat pump systems with the surrounding ground is quite important for design and energy calculation procedures. Building design load calculations, building energy calculations, ...
Mechanisms governing onset of sliding friction
(2014-12)
Experimental observations on slip onset during quasistatic shearing of bimaterial interface are presented in this study. Although friction has been a subject of multi-disciplinary research for many decades, events surrounding ...
Advancements in the simulation of ground source heat pump systems
(2014-05)
With ground source heat pump systems becoming an increasing focus in the building energy efficiency sector, fully understanding their behavior is key. For systems such as these, computer simulation is typically performed ...
Experimental and theoretical investigation of effect of fin geometry on frost formation on microchannel heat exchangers
(2012-07)
Scope and Method of Study:
Higher order and dynamic CFD for aeroelastic simulations
(2011-12)
This dissertation develops and analyzes higher order computational fluid dynamics simulations for coupled fluid-structure interactions as well as large deflection vehicle motions. The flow regime ranges across subsonic, ...
New techniques for clustering, selection of number of histogram bins, and estimation of quantiles of pairwise distances
(2011-12)
The emulation of Gestalt Laws was required for a proposed knowledge-based inference driven vision system. Emulating the Proximity gestalt law required a clustering technique that worked without: (a) the need for any input ...
