Loss Ratios of Different Scheduling Policies for Firm Real-time System : Analysis and Comparisons
(2017-11-27)Firm real time system with Poisson arrival process, iid exponential service times and iid deadlines till the end of service of a job, operated under the First Come First Served (FCFS) scheduling policy is well studied. In ... -
Harmonic Sound Source Separation in Monaural Music Signals
(2017-11-27)Sound Source Separation refers to separating sound signals according to their sources from a given observed sound. It is efficient to code and very easy to analyze and manipulate sounds from individual sources separately ... -
Demodulation of Narrowband Speech Spectrograms
(2017-11-22)Speech is a non-stationary signal and contains modulations in both spectral and temporal domains. Based on the type of modulations studied, most speech processing algorithms can be classified into short-time analysis ... -
Analysis of Local Field Potential and Gamma Rhythm Using Matching Pursuit Algorithm
(2017-11-17)Signals recorded from the brain often show rhythmic patterns at different frequencies, which are tightly coupled to the external stimuli as well as the internal state of the subject. These signals also have transient ... -
DSA Image Registration And Respiratory Motion Tracking Using Probabilistic Graphical Models
(2017-10-18)This thesis addresses three problems related to image registration, prediction and tracking, applied to Angiography and Oncology. For image analysis, various probabilistic models have been employed to characterize the image ... -
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, ... -
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 ... -
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 ... -
On Maximizing The Performance Of The Bilateral Filter For Image Denoising
(2017-07-07)We address the problem of image denoising for additive white Gaussian noise (AWGN), Poisson noise, and Chi-squared noise scenarios. Thermal noise in electronic circuitry in camera hardware can be modeled as AWGN. Poisson ... -
Study On DC-Link Capacitor Current In A Three-Level Neutral-Point Clamped Inverter
(2017-05-24)Three-level diode-clamped inverter is being widely used these days. Extensive research has been carried out on pulse width modulation (PWM) strategies for a three-level inverter. The most widely used PWM strategies are ... -
