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
(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 ...
Measurement and analysis of residual stresses in zirconia dental composites using micro X-ray diffraction
(2010-05)
Due to their aesthetic value and high compressive strength, dentists are utilizing ceramics as a material of choice for dental restorations. Among ceramics, zirconia provides high toughness and crack resistance. Residual ...
Study of frost growth on heat exchangers used as outdoor coils in air source heat pump systems
(2011-05)
Scope and Method of Study: During winter heating operation, the outdoor coil of a heat pump acts as an evaporator and when the ambient temperature is near freezing, the moisture in the atmospheric air freezes on the coil ...
Injection molded poly(ethylene terephthalate)-graphene nanocomposites
(2015-05)
Polymer nanocomposites are known for their superior properties (mechanical, thermal, etc.) compared to conventional composites. Nanoscale reinforcements are used to make such composites as they have fewer defects and higher ...
Closed cycle propulsion for small unmanned aircraft
(2015-07)
This study evaluates the merit of closed cycle propulsion systems for use in unmanned systems. The complexity and added weight of closed cycle engines is offset by benefits in high altitude performance, operation in polluted ...
Honeycomb in hybrid composite armor resisting dynamic impact
(2015-07)
Behind Armor Blunt Trauma (BABT) is an emerging problem in body armor due to excessive deformation resulting from projectile impact. A potential to reduce BABT has been identified by incorporating a honeycomb layer in a ...
