The Design And Analysis Of Optical Scanners For Optical Coherence Tomography
(Electrical Engineering, 2007-08-23)
A miniature fiber optic scanner capable of two-dimensional scanning for medical imaging is designed and developed. The scanner is actuated externally using an electromagnet. Nickel gel, a soft ferromagnetic material, is ...
Improved Refinement Coefficients' Coding In Scalable H.264
(Electrical Engineering, 2007-08-23)
This thesis proposes to replace the adaptation used to select VLC table for coding of the refinement coefficient by signaling to the decoder which table should be used for which macroblock type (Inter or Intra) in scalable ...
Emulation Of ASIC Based Network Processor On A FPGA Platform
(Electrical Engineering, 2007-08-23)
ABSTRACT
Exponential increase of device sizes and complexity of ASICs mandate the need
for design verification to meet timing specifications and functionality requirements.
Verification techniques are broadly implemented ...
Fiber Optic Scanner Using Electromagnetic Actuation With Different Ferromagnetic Materials
(Electrical Engineering, 2007-08-23)
A fiber optic scanner capable of scanning medical imaging actuated by an external magnetic field is designed and characterized using different magnetized and non magnetized ferromagnetic materials. Cobalt, Iron, Nickel, ...
Nonlinear Control Of Microelectromechanical Systems (MEMS) Devices
(Electrical Engineering, 2007-08-23)
Different actuation principles have been developed for MEMS but electrostatic actuators are the most common. A significant drawback in the use of electrostatic actuators for some applications is their nonlinear voltage to ...
Evaluation And Applications Of Gas Sensors
(Electrical Engineering, 2007-09-17)
Gas sensors are used widely for environmental and biomedical uses. This work focuses on verifying specifications of commercial-off-the-shelf (COTS) gas sensors and their particular applications.
The first chapter in this ...
Physics Based Time-frequency Analysis To Reduce Multi-bounce And Clutter In Radar Imaging
(Electrical Engineering, 2007-08-23)
The concept of time-frequency analysis of the scattered far field data from multiple targets is presented. The scattered data from the target is collected using a mono-static antenna configuration. The hardware system and ...
Optimization Of Coupling From A Sub-wavelength Metal Nanoaperture To A Gaussian Mode
(Electrical Engineering, 2007-09-17)
We model the surface resonance effects in a 1D-array of corrugations
on a metal-dielectric film with a sub-wavelength nanoaperture, following the
earlier work by Moreno et-al [Moreno:2003]. We are interested
in computing ...
Structural Similarity Based Image Quality Assessment: Pooling Strategies And Applications To Image Compression And Digit Recognition
(Electrical Engineering, 2007-08-23)
This thesis studies a recently proposed perceptual image similarity measure: the structural similarity (SSIM) index. Although still in its early stage, the SSIM index has demonstrated superior performance in a large number ...
FPGA Prototyping For Fast And Efficient Verification Of ASIC H.264 Decoder
(Electrical Engineering, 2007-08-23)
To improve compression efficiency, recent video compression standards such as H.264 use complex algorithms and various modes that demand more computational power. Consumer electronics industry requires a low power, compact ...
