Analysis and applications of melt expulsion during ultrasonic vibration-assisted laser surface processing
(2018-05)
Simultaneous application of ultrasonic vibrations during conventional material processing is recently gaining widespread attention due to enhancement of material removal mechanism and improvement in metallurgical quality. ...
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 ...
Vortex ring propagation in confined spheroidal domains and applications to cardiac flows
(2019-12)
Vortex ring formation is observed in the human cardiac left ventricle (LV) during diastole. Numerous studies to date have examined the intraventricular filling vortex for potential use in the diagnosis of cardiac dysfunction. ...
Asymmetric surface dielectric barrier discharge as a novel method for biological decontamination
(2015-12)
Scope and Method of Study:
Residual stress in all ceramic zirconia-porcelain dental system by simulation and nanoindentation
(2012-07)
Scope and Method of Study:
Oil retention and its effects on pressure drop and heat transfer in microchannel heat exchangers of air conditioning and refrigeration system
(2015-07)
In vapor compression, a small portion of the compressor oil circulates with the refrigerant through the cycle components, while most of the oil stays in the compressor. The presence of oil increases the pressure losses and ...
