3D Volume Reconstruction From 2D Plenoptic Data Using FFT-Based Methods
(2015-06-15)
Traditional imaging modalities produce images by capturing a 2D slice of the 4D light field. This is an inherently lossy conversion, as the angular information contained in the light field is ignored. Light-field imaging ...
Testing and Diagnosis of CMOS Open Defects in the Presence of Common Hazards
(2015-07-29)
CMOS open defects are breaks in wires or defective transistors within some library cell causing pull up or pull down failure of the defective gates. Traditionally, TSOF (transistor stuck-open fault) is used to model such ...
Advanced RC Phase Delay Capacitive Sensor Interface Circuits for MEMS
(2015-05-06)
Many types of sensors in MEMS technology convert a measurand to a proportional change in capacitance. One of the techniques of measuring capacitance is utilizing the phase delay of an RC network with a resistor and the ...
Analytical Study of the Effects of Grid Resistance on Grid-Connected PV Systems: Modeling and Simulation
(2015-04-22)
Lot of issues associated with grid-connected PV system have appeared. One of the issues is the variations of grid impedance. In the traditional real and reactive power calculations, the resistance of the transmission line ...
Broadband Radio Frequency Transmitter for Magnetic Resonance Imaging
(2015-07-14)
In Magnetic Resonance Imaging (MRI) application, radio frequency (RF) coils play an important role to excite the nuclei inside the imaging subject and receive MR generated signals. To achieve optimal transmit efficiency/receive ...
Optimization Approaches for a Dubins Vehicle in Coverage Planning Problem and Traveling Salesman Problems
(2015-05-07)
The motivation of this dissertation is a path planning task for an autonomous robot-trailer system in geophysical surveys. The path planning task includes two main stages. In the first stage, an efficient coverage path is ...
Investigation of RF Noise in 28nm RF CMOS Using TCAD
(2015-05-07)
State of art of 28 nm RF MOSFET is studied using sentaurus process and device tools.
DC characteristics, such as C-V, Rs, Rd and I-V curves are calibrated by adjustment of
physics model. The relationship between saturation ...
3D Surface Reconstruction Based On Plenoptic Image
(2015-07-23)
Light- field cameras, also known as plenoptic cameras, have recently become available
to the consumer market. Plenoptic cameras can collect the 4D light field information and
represent it in a single photograph. This ...
Wide Temperature Range SiGe HBT Noise Parameters Modeling and LNA Design
(2015-06-24)
This work investigates SiGe HBT noise parameters and impedance matched Low-Noise
Ampli ers(LNAs) intended for operation across a wide temperature range from 93 to 393
K. For the IBM 5AM technology used, noise performance ...
On joint reconstruction of spin density, R2* decay and off-resonance frequency maps through a single-shot or multi-shot acquisition in magnetic resonance imaging
(2015-07-28)
Joint reconstruction of $R_2^*$ and off-resonance frequency maps is very important in many MR applications. For example, $R_2^*$ quantification can be applied to BOLD functional MRI, iron deposition measurement, and early ...
