New techniques for data clustering and color image segmentation
(2013-05)
The objectives of this work are twofold: (1) to create an improved automatic clustering procedure that produces results consistent with manual clustering of data points by humans; and (2) to find an improved technique for ...
Responses of vascular cells to shear stress and diabetes-associated metabolic dysfunction
(2016-12)
Cardiovascular disease (CVD) is the leading cause of death worldwide, accounting for 30% of all deaths. Coronary artery disease (CAD - narrowing of arteries), most common type of CVD, results in altered shear stress that ...
Experimental measurements and modeling of void fraction and pressure drop in upward and downward inclined non-boiling gas-liquid two phase flow
(2015-07)
The prime objective of this research is to contribute to the fundamental understanding of the effect of upward and downward pipe inclinations on flow patterns, void fraction and pressure drop in non-boiling gas-liquid two ...
Mechanical properties of a new high specific strength honeycomb from amorphous metal
(2015-05)
Using metallic glasses as base materials, Amorphous Metal Honeycombs (AMHs) with a teardrop cellular geometry were manufactured. A new analytical model was proposed to predict the relative density and axial compressive ...
Optical response of undoped and doped zinc oxide thin films
(2017-07)
The optical response of undoped and doped ZnO thin films was investigated. Epitaxial films were deposited on c-plane and r-plane sapphire using pulsed laser deposition and were characterized with a combination of ...
Understanding avian soaring to extend UAV mission endurance through remote detection of thermal updrafts
(2016-05)
Thermal updrafts can be utilized to increase an aircraft's flight endurance and range. However, much of the discussion involving thermal updrafts comprise of flight techniques within a known thermal updraft and very little ...
Locomotion of a cylindrical rolling robot with a shape changing outer surface
(2017-03)
A cylindrical rolling robot is developed that generates torque by changing shape (eccentricity) of its elliptical outer surface. Shape change commences four times per revolution, whenever one of four elliptical axes rotates ...
Parameter estimation of a nonlinear Burger's model using nanoindentation and finite element-based inverse analysis
(2016-05)
Nanoindentation involves probing a hard diamond tip into a material, where the load and the displacement experienced by the tip is recorded continuously. This load-displacement data is a direct function of material's innate ...
Asymmetric surface dielectric barrier discharge as a novel method for biological decontamination
