Interference mitigation effects on synthetic aperture radar coherent data products
(2015-07)
Both radio frequency interference from sources external to the synthetic aperture radar system and techniques to mitigate radio frequency interference can degrade the quality of the image products. Often it is the second ...
Efficient schemes to size transistors for optimal delay by solving fanout branches with balancing algorithm
(2015-05)
High performance digital system requires minimal logic and properly sized transistor to operate in all PVT corners. Specifically, high-speed data-path design is mostly about optimizing the system for better timing. In this ...
Visual masking in natural scenes: Database, models, and an application to perceptual image coding
(2015-05)
Studies of visual masking have provided a wide range of important insights into the processes involved in visual coding. However, very few of these studies have employed natural scenes as masks, and little is known on how ...
Measurement and analysis of natural video masked dynamic discrete cosine transform noise detectability
(2015-05)
Lossy video compression lowers fidelity and can leave visual artifacts. Current video compression algorithms are guided by quality assessment tools designed around subjective data based on aggressive video compression. ...
Front end of a 900MHz RFID for biological sensing
(2015-12)
This thesis presents the front end of a 900MHz passive RFID for biological sensing. The components blocks of the front end consist of power harvester, switch capacitor voltage regulator, phase lock loop and a modulator and ...
Multiobjective differential evolution based on fuzzy performance feedback: Soft constraint handling and its application in antenna designs
(2015-12)
The recently emerging Differential Evolution is considered one of the most powerful tools for solving optimization problems. It is a stochastic population-based search approach for optimization over the continuous space. ...
CMOS circuit speed and power optimization using simplified RC delay model
(2015-05)
A simplified RC delay model which is expressed explicitly in terms of transistor widths is presented to easily perform circuit analysis and quickly optimize the transistor widths for delay and power without having to do ...
Robot skill learning through human demonstration and interaction
(2015-05)
Nowadays robots are increasingly involved in more complex and less structured tasks. Therefore, it is highly desirable to develop new approaches to fast robot skill acquisition. This research is aimed to develop an overall ...
Strategies for improving efficiency and efficacy of image quality assessment algorithms
(2015-05)
Image quality assessment (IQA) research aims to predict the qualities of images in a manner that agrees with subjective quality ratings. Over the last several decades, the major impetus in IQA research has focused on ...
