Methodologies For Automated Microassembly
(Mechanical Engineering, 2008-08-08)
The development of micromachining technologies has provided wide applications in micro sensing and actuation. However, most of the demonstrated devices are selectively constructed by fabrication processes that are limited ...
An Experimental Study On Thermal Bonding Effects Of PMMA Based Micro-devices Using Hot Embossing
(Mechanical Engineering, 2008-08-08)
Basic configuration and functioning of various subsystems of a developed HEMM system for thermal bonding are discussed. The bond strength and micro channel geometry degradations dependence on controlled process parameters ...
A Mathematical Model Development And Sensitivity Analysis Of Two Photon Polymerization For 3D Micro/nano Fabrication
(Mechanical Engineering, 2008-09-17)
Two photon polymerization (2PP) is an effective technique for the fabrication of complex polymeric 3-D micro/nano features using ultrashort pulses from a NIR laser source. The photosensitive material absorbs two photons ...
Design And Analysis Of Multi-functional Laparoscopic Tool
(Mechanical Engineering, 2008-04-22)
Laparoscopic tools have been developed over many years, but there is a need for a laparoscopic tool that can be used for multiple purposes without the need to be removed and reinserted in the body. This thesis discusses ...
Closed-form Development Of A Family Of Higher Order Tetrahedral Elements Through The Fourth Order
(Mechanical Engineering, 2008-08-08)
This research is concerned with the development and implementation of a family of tetrahedral elements through the fourth order. The straight-sided tetrahedral elements are developed in closed-form. This work investigates ...
The Development Of A Finite Element Tool For The Calculation Of Beam Cross Section Properties
(Aerospace Engineering, 2008-09-17)
Cross section properties are crucial in the analysis and design of beams as they play a key role in the determination of the stress state encountered. The development of an FEM tool in MATLAB for the calculation of beam ...
Analysis And Optimization Of A Crashworthy Helicopter Seat
(Mechanical Engineering, 2008-08-08)
The objective of a crashworthy seat is to improve the survivability of occupants (cockpit and cabin) in helicopter crashes. All modern helicopter seats are equipped with an energy absorber to reduce lumbar spine load during ...
