Signal Processing Algorithms For Digital Image Forensics
(2010-03-19)Availability of digital cameras in various forms and user-friendly image editing softwares has enabled people to create and manipulate digital images easily. While image editing can be used for enhancing the quality of the ... -
Signal Processing and Coding for Two-Dimensional Magnetic Recording
Many novel approaches have been proposed to improve storage densities of magnetic recording beyond the existing 1 Tb/in2. These include heat-assisted magnetic recording (HAMR), bit-patterned media (BPM) and two-dimensional ... -
Signcryption in a Quantum World
With recent advancements and research on quantum computers, it is conjectured that in the foreseeable future, sufficiently large quantum computers will be built to break essentially all public key cryptosystems currently ... -
Silicon photodetector integrated silicon nitride-on-SOI platform for communication and sensor applications
Driven by the exponential growth of data tra c, current infrastructure and standards are evolved to meeting the requirements. In long haul communication, 1550/1310 nm based singlemode ber technology is a commercially ... -
Silk-based Biomaterials for Wound Care and Tissue Regeneration
For most individuals, wound healing is a highly organized, straightforward process. However, there are instances where external intervention becomes necessary to support the body’s innate healing mechanism. In this thesis, ... -
Similarity between Scalar Fields
(2017-10-05)Scientific phenomena are often studied through collections of related scalar fields such as data generated by simulation experiments that are parameter or time dependent . Exploration of such data requires robust measures ... -
A simple method for measurement of high power, inline beam quality of high-power lasers
Over the past few decades, applications of high-power fiber laser in the area of material processing, medicine, defence, high precision micro-machining etc., is rapidly increasing. The primary reason behind thriving ... -
Simple Models For The Mean And Transient Intertropical Convergence Zone And Its Northward Migration
(2011-11-16)Satellite data have shown that east-west oriented cloud bands, known as Intertropical convergence zone (ITCZ), propagate eastwards along the equator throughout the year and northwards during boreal summer on intraseasonal ... -
Simulation and Characterization of Streamflow Time Series
Streamflow can be partitioned into distinct time scales to better understand the underlying governing processes: fast flow, representing surface runoff controlled mainly by meteorological processes that operate over ... -
Simulation and Study of Noise Generated due to Turbulent Boundary Layer in Towed Hydrophone Array
In this thesis, a wave propagation based analytical model is developed for an underwater towed array. The towed array is modeled as an in finite tube filled with a certain liquid and submerged in an in finite volume of ... -
Simulation Based Algorithms For Markov Decision Process And Stochastic Optimization
(2010-08-06)In Chapter 2, we propose several two-timescale simulation-based actor-critic algorithms for solution of infinite horizon Markov Decision Processes (MDPs) with finite state-space under the average cost criterion. On the ... -
Simulation of complex plastic flows in metal sliding and cutting
Metal manufacturing encompasses a broad range of mechanical transformation processes that shape native metal into useful forms. These processes generally involve the interaction of a hard tool with a specimen / workpiece, ... -
Simulations of Aerosol Species over the Indian Region: Evaluation and Improvements
Increasing aerosol loading over the south Asian region, holds a potential of, perturbing the south Asian monsoon system and the Himalayan glacial coverage, and thus affecting lives of (1/4)th of the world’s population. ... -
Simultaneous Studies Of Electrical Contact Resistance And Thermal Contact Conductance Across Metallic Contacts
(2010-12-07)Contact resistance is the most important and universal characteristic of all types of electrical and thermal contacts. Accurate measurement of contact resistance is important, because it serves as a measure for judging the ...
