CMOS Stress Sensor Circuits
(2008-09-09)
Two CMOS piezoresistive stress sensor circuits based on piezoresistive MOSFETs (PiFETs) are the focus of this dissertation. The first design is a multiplexed array of 512 piezoresistive sensors fabricated on a 2.2 by 2.2mm2 ...
Design and Development of a GPS Intermediate Frequency and IMU Data Acquisition System for Advanced Integrated Architectures
(2008-09-09)
Advanced levels of GPS and INS integration, including Deeply Integrated and Ultra-
Tightly Coupled, have been reported to provide significant gains in anti-jamming capa-
bility and reduced susceptibility to loss of GPS ...
Tag line tracking and Cardiac Motion Modeling from Tagged MRI
(2008-09-09)
Magnetic resonance (MR) tagging magnetically labels specified regions of the myocardium, which appear in the MR images with a spatially encoded pattern of dark stripes called tag lines. The deformation of these tag lines ...
Flip Chip and Lid Attachment Assembly Process Development
(2008-09-09)
Flip chip technology offers numerous advantages over conventional packages by virtue of its electrical performance, greater input/output (I/O) flexibility and small size. This study focuses on two flip chip assembly process ...
Kalman Filter Based Tracking Algorithms For Software GPS Receivers
(2008-09-09)
In this thesis several new Kalman filter based tracking algorithms for GPS software
receivers are presented. Traditional receivers use Costas loops and Delay Lock Loops
(DLL) to track the carrier and Pseudo-Random Noise ...
A Parallel Implementation of Fault Simulation on a Cluster of Workstations
(2008-09-09)
Parallel simulation on a cluster workstations is one method by which fault simulation time for large circuits can be reduced significantly. To get near-linear speedups from parallel processing, parallelization methods ...
Experimental and Theoretical Investigation of Contact Resistance and Reliability of Lateral Contact Type Ohmic MEMS Relays
(2008-09-09)
In this thesis, the reliability of electrostatically actuated ohmic contact type MEMS relays has been investigated. Multi-contact MEMS relays using electrostatic comb-drive actuators have been used in this study. The ...
Weak Signal Reception Using Software Defined Radios and a Two-Element Antenna Array
(2008-09-09)
Software Defined Radio (SDR) is a quickly emerging technology. SDR removes
the signal processing task from the analog hardware portion of a radio and places it into
the Digital Signal Processing (DSP) domain. Many ...
Cooperative Robotics Using Wireless Communication
(2008-09-09)
Cooperative Robotics has to do with the use of multiple robotic agents assisting each other to perform a task that is either too difficult or impossible for one robot to perform alone. It is a multi-disciplinary field ...
Heterogeneity-Aware Approaches to Optimizing Performance of Computing and Communication Tasks
(2008-09-09)
As the domain of computing and communication systems grows, heterogeneity among computers and subnetworks employed for a task also increases. It is important to understand how heterogeneity affects performance of computing ...
