Design and analysis of feedback and feedforward control systems for web tension in roll-to-roll manufacturing
(2015-05)
In Roll-to-Roll (R2R) manufacturing, efficient transport of flexible materials (webs) on rollers requires simultaneous control of web speed and tension. Webs experience disturbing forces during transport due to nonideal ...
Modeling and control of transport behavior of moving webs through heat transfer processes
(2015-07)
Heat transfer processes are widely employed in Roll-to-Roll (R2R) process machines to heat/cool moving webs. The general goal is to efficiently transport webs over heating/cooling rollers and ovens while achieving the ...
Fracture behavior and time dependent properties of poss-epoxy nanocomposites
(2015-07)
This study investigates the fundamental mechanism that governs the influence of glycidyl POSS on the time-dependent behavior of epoxy-POSS composite as a function of added weight percent. Different formulation of POSS-epoxy ...
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 ...
Asymmetric surface dielectric barrier discharge as a novel method for biological decontamination
(2015-12)
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 ...
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 ...
