An Evaluation Framework and Decision-Making Model for Defense Acquisition Projects - Real Options and Multi-Criteria Decision Analysis (MCDA)
(2014-05-30)
In this dissertation, strategic decision--making models based on real options and multi-criteria decision analysis (MCDA) are proposed to assess the value of risky defense acquisition projects. A large-scale acquisition ...
A Novel Three Dimensional Wafer Level Chip Scale Packaging Technology-Manufacturing Process Development and Reliability Characterizations
(2010-08-05)
Three Dimensional (3D) packaging has moved to the forefront in the electronic packaging industry, as the trend toward higher performance, smaller form factor and lower cost continues.

A Markov Chain Dynamic Social Network Modeling and Simulation to Assess the Impact of Out-of-School Suspensions on Dropouts and Truancy
(2010-08-03)
Generally, a social network is mainly concerned with actors, the actions of actors, and the interactivities among actors in a community. Employing graph theory to represent overall social network structure, this study ...
Decision Models for a Two-Stage Supply Chain Planning under Uncertainty with Time-sensitive Shortages and Real Option Approach
(2010-03-23)
The primary objective of this research is to develop analytical models for typical supply
chain situations to help inventory decision-makers. We also derive closed form solutions
for each model and reveal several ...
The Effect of Varying Work Order Sequences on Physiological Responses in Combined Manual Material Handling
(2010-12-06)
Despite technological advances in the workplace that reduces the physical requirements of the worker, musculoskeletal disorders (MSDs) continue to be a concern. This is particularly the case in the manual material handling ...
SMT Line Improvements for High Mix, Low Volume Electronics Manufacturing
(2011-06-03)
This work covers two major projects aimed at increasing quality and efficiency on a high mix, low volume surface mount electronics production line. Specifically the installation of a ten zone reflow oven and an enhanced ...
Test Planning and Validation through an Optimized Kriging Interpolation Process in a Sequential Sampling Adaptive Computer Learning Environment
(2012-07-27)
This dissertation explores Kriging in an adaptive computer learning environment with sequential sampling. The idea of this Design for Kriging (DFK) process was first mentioned in [1] titled “Kriging for Interpolation in ...
Modeling Human Perception of Postural Stress
(2013-04-22)
This work investigated the discomfort-time sequences of SPH tasks in an effort to determine the existing relationship between perceived discomfort and posture holding time. This study proposed the power function as an ...
The Effects of Thermal Aging on the Mechanical Behavior of Fine Pitch Electronics Packages
(2013-01-07)
The direction of Electronics packaging industry is to design smaller packages
with higher complexity while focusing on Sn-Ag-Cu as the alloy of choice for lead free
electronics assembly. While performance capabilities ...
