Methods for Text Segmentation from Scene Images
(2017-09-27)Recognition of text from camera-captured scene/born-digital images help in the development of aids for the blind, unmanned navigation systems and spam filters. However, text in such images is not confined to any page layout, ... -
Plan Bouquets : An Exploratory Approach to Robust Query Processing
(2017-09-26)Over the last four decades, relational database systems, with their mathematical basis in first-order logic, have provided a congenial and efficient environment to handle enterprise data during its entire life cycle of ... -
Data Fusion Based Physical Layer Protocols for Cognitive Radio Applications
(2017-09-26)This thesis proposes and analyzes data fusion algorithms that operate on the physical layer of a wireless sensor network, in the context of three applications of cognitive radios: 1. Cooperative spectrum sensing via binary ... -
Bitrate Reduction Techniques for Low-Complexity Surveillance Video Coding
(2017-09-26)High resolution surveillance video cameras are invaluable resources for effective crime prevention and forensic investigations. However, increasing communication bandwidth requirements of high definition surveillance videos ... -
Reactive Power Planning And Operation of Power Systems with Wind Farms for Voltage Stability Improvement
(2017-09-23)In recent years, the electric power industry around the world is changing continuously due to transformation from regulated market structure to deregulated market structure. The main aim of the transformation of electric ... -
Energy Harvesting Wireless Sensor Networks : Performance Evaluation And Trade-offs
(2017-09-23)Wireless sensor networks(WSNs) have a diverse set of applications such as military surveillance, health and environmental monitoring, and home automation. Sensor nodes are equipped with pre-charged batteries, which drain ... -
Optimal Control of Information Epidemics in Homogeneously And Heterogeneously Mixed Populations
(2017-09-23)Social networks play an important role in disseminating a piece of information in a population. Companies advertising a newly launched product, movie promotion, political campaigns, social awareness campaigns by governments, ... -
Neuronal Dissimilarity Indices that Predict Oddball Detection in Behaviour
(2017-09-23)Our vision is as yet unsurpassed by machines because of the sophisticated representations of objects in our brains. This representation is vastly different from a pixel-based representation used in machine storages. It is ... -
Retweet Profiling - Study Dissemination of Twitter Messages
(2017-09-23)Social media has become an important means of everyday communication. It is a mechanism for “sharing” and “resharing” of information. While social network platforms provide the means to users for resharing/reblogging (aka ... -
Distributed Algorithms for Power Allocation Games on Gaussian Interference Channels
(2017-09-20)We consider a wireless communication system in which there are N transmitter-receiver pairs and each transmitter wants to communicate with its corresponding receiver. This is modelled as an interference channel. We propose ... -
Feature Adaptation Algorithms for Reinforcement Learning with Applications to Wireless Sensor Networks And Road Traffic Control
(2017-09-20)Many sequential decision making problems under uncertainty arising in engineering, science and economics are often modelled as Markov Decision Processes (MDPs). In the setting of MDPs, the goal is to and a state dependent ... -
Design And Control of Power Converters for Renewable Energy Systems
(2017-09-20)Renewable energy sources normally require power converters to convert their energy into standardized regulated ac output. The motivation for this thesis is to design and control power converters for renewable energy ... -
Spectral And Temporal Zero-Crossings-Based Signal Analysis
(2017-09-20)We consider real zero-crossing analysis of the real/imaginary parts of the spectrum, namely, spectral zero-crossings (SZCs). The two major contributions are to show that: (i) SZCs provide enable temporal localization of ... -
Low Power And Low Spur Frequency Synthesizer Circuit Techniques For Energy Efficient Wireless Transmitters
(2017-09-07)There has been a huge rise in interest in the design of energy efficient wireless sensor networks (WSN) and body area networks (BAN) with the advent of many new applications over the last few decades. The number of sensor ... -
Fundamentals Limits Of Communication In Interference Limited Environments
(2017-08-21)In multiuser wireless communications, interference not only limits the performance of the system, but also allows users to eavesdrop on other users’ messages. Hence, interference management in multiuser wireless communication ... -
Optimal Amplify-And-Forward Relaying For Cooperative Communications And Underlay Cognitive Radio
(2017-08-21)Relay-assisted cooperative communication exploits spatial diversity to combat wireless fading, and is an appealing technology for next generation wireless systems. Several relay cooperation protocols have been proposed in ... -
Minimization Problems Based On A Parametric Family Of Relative Entropies
(2017-08-21)We study minimization problems with respect to a one-parameter family of generalized relative entropies. These relative entropies, which we call relative -entropies (denoted I (P; Q)), arise as redundancies under mismatched ... -
