Impact Of Viscoelastic Material Characterization Of PCB's On Thermomechanical Properties Of QFN Thick Package Under Thermal Cycling
(Mechanical Engineering, 2015)
The QFN component package is a quad flat pack (QFP) with “no-leads”, where the electrical contact to the printed circuit board (PCB) is made through soldering of the lands underneath the package body rather than the ...
FABRICATION AND CHARACTERIZATION OF LOW-DENSITY POLYMERIC MATERIALS WITH 3D MICROSTRUCTURES
(2015-12-04)
Low-density polymeric materials with octet-truss and quad-truss 3D microstructures were studied. The materials with 3D microstructures were created using digital light processing technology with polyethylene glycol (PEG). ...
Characterization Of Flapping Wing Aerodynamics And Flight Dynamics Analysis Using Computational Methods
(Aerospace Engineering, 2015)
Insect flight comes with a lot of intricacies that cannot be explained by conventional aerodynamics. Even with their small-size, insects have the ability to generate the required aerodynamic forces using high frequency ...
Semi-active Suspension System Using A Magnetorheological Damper
(Mechanical Engineering, 2015)
Magnetorheological (MR) Fluid changes its yield strength when it is subjected to a magnetic field. When this fluid is used inside a damper, it has the ability to change the damping coefficients when it is acted upon by ...
Evaluating and augmenting fuel-saving benefits obtained in aircraft formation flight
(University of Texas at Arlington, 2015-05)
When an aircraft flies, it generates wake vortices, which induce a non-uniform wind distribution in its wake. A trail aircraft, placed in the wake of a lead's aircraft vortices experiences this non-uniform wind distribution ...
ENERGY AND WATER IMPACTS OF DATA CENTER COOLING SYSTEMS: A TRIPLE BOTTOM LINE ASSESSMENT FOR FACILITY DESIGN
(2015-12-10)
Increasingly, society is being transferred to a dependence upon electronic technologies and networked systems, usually accessed via the internet. Physically, these systems reside within clusters of servers and storage ...
