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 ...
Improved IPTV channel change times through multicast caching of pre-selected channels
(2014-12)
IPTV has grown in recent years to an estimated 100 million users worldwide. IPTV uses IGMP processes to stream an individual channel to a user until the next channel change when the current channel is stopped and the new ...
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 ...
Cooperative control, learning and sensing in mobile sensor networks
(2011-12)
Scope and Method of Study:
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 ...
Enhanced rateless coding and compressive sensing for efficient data/multimedia transmission and storage in AD-HOC and sensor networks
(2012-12)
In this dissertation, we investigate the theory and applications of the novel class of FEC codes called rateless or fountain codes in video transmission and wireless sensor networks (WSN). First, we investigate the rateless ...
