Passive Pendulum Balancer for Rotor Systems
(2008-09-09)
Automatic, passive self-balancing systems are important tools for reducing the effects of synchronous vibration in a variety of rotating machinery. Such systems are ideally capable of precise balancing, subject to certain ...
Vibration and Acoustical Properties of Sandwich Composite Materials
(2008-09-09)
In applications where the use of lightweight structures is important, the introduction of a viscoelastic core layer, which has high inherent damping, between two face sheets, can produce a sandwich structure with high ...
Methods for Minimizing Navigation Errors Induced by Ground Vehicle Dynamics
(2008-09-09)
A navigation system was designed using an extended Kalman filter for an autonomous ground vehicle competing in the 2005 DARPA Grand Challenge. An overview of this system is provided, and errors in the navigation solution ...
Thermo-mechanical Reliability Models for Life Prediction of Area Array Electronics in Extreme Environments
(2008-09-09)
The increasing functionality in modern microelectronics requires more complexity in less space and more reliability at lower cost. Demands on miniaturization have lead to the evolution of several types of area array packages ...
A Study of Crack-Inclusion Interaction Using Moiré Interferometry and Finite Element Analysis
(2008-09-09)
Failure of composite materials is intrinsically linked to the fundamental problem of a matrix crack interacting with a second phase inclusion. In this work, the critical issue of matrix-inclusion debonding in the presence ...
Fabrication, Filling, Sealing and Testing of Micro Heat Pipes
(2008-09-09)
Micro heat pipes are small and passive heat transfer devices. Research is going on in its applications ranging from using them in high powered electronic devices to using them during brain surgeries. A combination of silicon ...
Considerations on Optimum Design of Micro Heat Pipe Sinks Using Water as Working Fluid
(2008-09-09)
The successful operation of RF wideband gap devices dissipating high levels of heat
flux requires effective cooling techniques. One of the most promising thermal management
strategies is the use of micro heat pipes (MHP). ...
