Sputter Deposited ZrC and NbC Thin Films – Studies on Microstructure, Texture and Hardness
(2018-08-29)Transition metal carbides have great industrial importance with a wide area of applications. Unlike many ceramic materials which can be produced from raw materials found in nature, the refractory carbides generally do not ... -
Analytical Modelling and Non-linear Characterisation of Piezoelectric Materials for Actuation and Vibration Control of Beams
(2018-08-29)The use of piezoelectric materials for actuation, and vibration suppression of thin beams, is the subject of study in this doctoral thesis. The initial focus is set on reducing beam vibrations with resistively shunted ... -
Experimental and Molecular Dynamics Simulation Study of Viscosity of Polymer Nanocomposites
(2018-08-29)One of the important dynamic parameter characterizing the properties of polymer nanocomposite is viscosity. It is a quantity of interest on macroscopic scale also. A thorough study of viscosity in case of polymer nanocomposite ... -
Enhancing GPGPU Performance through Warp Scheduling, Divergence Taming and Runtime Parallelizing Transformations
(2018-08-29)There has been a tremendous growth in the use of Graphics Processing Units (GPU) for the acceleration of general purpose applications. The growth is primarily due to the huge computing power offered by the GPUs and the ... -
Sparsity Motivated Auditory Wavelet Representation and Blind Deconvolution
(2018-08-29)In many scenarios, events such as singularities and transients that carry important information about a signal undergo spreading during acquisition or transmission and it is important to localize the events. For example, ... -
Supporting Real-Time, Automated Evaluation of Difficulty in Manual Assembly
(2018-08-29)Product designers address the costs of assembly during the design process. Design process can be more efficient if assembly issues could be addressed early in its design process. Doing this requires the ability to assess ... -
Multi-Core Memory System Design : Developing and using Analytical Models for Performance Evaluation and Enhancements
Memory system design is increasingly influencing modern multi-core architectures from both performance and power perspectives. Both main memory latency and bandwidth have im-proved at a rate that is slower than the increase ... -
Understanding the Role of Rab22A in Recycling Endosome Biogenesis and Melanocyte Pigmentation
(2018-08-28)Recycling embosoms (REs) are transient intermediates of endosomal network, constantly generated from early/sorting endosomes (EEs/SEs). Conventionally, these organelles function in recycling of many growth/nutrient/signalling ... -
Diffusion-Controlled Growth of Phases in Metal-Tin Systems Related to Microelectronics Packaging
(2018-08-28)The electro–mechanical connection between under bump metallization (UBM) and solder in flip–chip bonding is achieved by the formation of brittle intermetallic compounds (IMCs) during the soldering process. These IMCs ... -
Benchmarking and Scheduling Strategies for Distributed Stream Processing
(2018-08-20)The velocity dimension of Big Data refers to the need to rapidly process data that arrives continuously as streams of messages or events. Distributed Stream Processing Systems (DSPS) refer to distributed programming and ... -
A Fine-Grained Dynamic Information Flow Analysis for Android Apps
(2018-08-20)Android has been steadily gaining popularity ever since its launch in 2008. One of the major factors for this is the easy availability of a large variety of apps. They range from simple apps such as calculator apps to apps ... -
On a Divide-and-Conquer Approach for Sensor Network Localization
(2018-08-20)Advancement of micro-electro-mechanics and wireless communication have proliferated the deployment of large-scale wireless sensor networks. Due to cost, size and power constraints, at most a few sensor nodes can be equipped ... -
Studies on Silicone Rubber Insulators used for High Voltage Transmission
(2018-08-20)Recently high temperature vulcanized (HTV) silicone rubber (SIR) / polymeric/composite insulators are gaining wider acceptance as overhead transmission line insulators for extra high voltage (EHV) and ultra-high voltage ... -
Feature Selection under Multicollinearity & Causal Inference on Time Series
(2018-08-20)In this work, we study and extend algorithms for Sparse Regression and Causal Inference problems. Both the problems are fundamental in the area of Data Science. The goal of regression problem is to nd out the \best" ... -
Computational Analyses of Protein Structure and Immunogen Design
(2018-08-20)The sequence of a polypeptide chain determines its structure which in turns determines its function. A protein is stabilized by multiple forces; hydrophobic interaction, electrostatic interactions and hydrogen bond formation ... -
Precipitate Growth and Coarsening in Ternary Alloys
(2018-08-20)We have studied precipitate growth and coarsening in ternary alloys using two different phase held models. The first one is a ternary extension of the classical Cahn-Hilliard (C-H) model in which both the phases are ... -
Falcon : A Graph Manipulation Language for Distributed Heterogeneous Systems
(2018-08-20)Graphs model relationships across real-world entities in web graphs, social network graphs, and road network graphs. Graph algorithms analyze and transform a graph to discover graph properties or to apply a computation. ... -
Contaminant Transport through Soil and Effect of Bentonite and super-absorbent Polymer on Transport Parameters
(2018-08-20)The aim of this present research is to improve the containment properties of clayey soil by the use of bentonite and polymers as the additives. Clayey soils are generally used for the control of soil and water pollutions ... -
Resource Allocation in Femtocells via Game Theory
