Optical Diffraction Tomography for the Refractive Index Profiling of Objects with Large Space-Bandwidth product
(2018-05-25)The primary goal of this work is to arrive at direction tomography (DT) algorithms freed from the severe linearization in the formulation, and as-assumptions on variation of the refractive index distribution (RID), involved ... -
Optical, Structural and Mechanical Characterization of Ultrafast Laser Inscribed Chalcogenide Waveguides
In recent years, chalcogenide glasses have established their usefulness as attractive candidates for the fabrication of all-optical devices and mid infra-red lasers. These glasses possess low phonon energy and hence high ... -
Optoelectronic Properties of Graphene Based Van-der-Waals Hybrids
Light matter interactions in atomically thin van der Waals materials have attracted significant attention in recent day [1–6]. Although the thickness does not exceed few nano-meters, such an atomically thin materials alone ... -
The Pick-Nevanlinna Interpolation Problem : Complex-analytic Methods in Special Domains
(2018-06-13)The Pick–Nevanlinna interpolation problem, in its fullest generality, is as follows: Given domains D1, D2 in complex Euclidean spaces, and a set f¹ zi; wiº : 1 i N g D1 D2, where zi are distinct and N 2 š+, N 2, find ... -
Point-of-Care High-throughput Optofluidic Microscope for Quantitative Imaging Cytometry
(2018-03-15)Biological research and Clinical Diagnostics heavily rely on Optical Microscopy for analyzing properties of cells. The experimental protocol for con-ducting a microscopy based diagnostic test consists of several manual ... -
Polymer Assisted Dispersion of Carbon Nanotubes (CNTs) and Structure, Electronic Properties of CNT - Polymer Composite
(2018-05-21)Carbon nanotubes possess various unique and interesting properties. They have very high thermal and electrical conductivities, high stiffness, mechanical strength, and optical properties. Due to these properties, CNTs are ... -
A Probing System for Dynamic Mode Atomic Force Microscopy Based on Specialized Probes
The dynamic mode atomic force microscope (AFM) is a versatile tool that uses a resonantly excited micro-cantilever probe to obtain a sample’s topography and to characterize its material properties. While a number of useful ... -
A Probing System with Replaceable Tips for Three Dimensional Nano-Metrology
(2018-06-14)With increase in the number of three dimensional (3-D) nanometer-scale objects that are being either fabricated or studied, there is a need to accurately characterize their geometry. While the Atomic force microscope (AFM) ... -
Probing the Beyond Standard Model Physics in Top Quark and Dark Matter Sectors
(2018-05-22)The Standard Model (SM) of particle physics provides the theoretical framework to describe the fundamental interactions among elementary constituents of matter. SM is supported by experiments to a high degree of accuracy, ... -
Probing the Nature of Dark Matter in the Universe
The dark matter is the most dominating matter candidate and a key driving force for the structure formation in the universe. Despite decade-long searches, the precise nature and particle properties of dark matter are ... -
The Space of Metric Measure Spaces
(2018-05-22)This thesis is broadly divided in two parts. In the first part we give a survey of various distances between metric spaces, namely the uniform distance, Lipschitz distance, Hausdor distance and the Gramoz Hausdor distance. ... -
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 ... -
Stabilization Schemes for Convection Dominated Scalar Problems with Different Time Discretizations in Time dependent Domains
(2018-05-21)Problems governed by partial differential equations (PDEs) in deformable domains, t Rd; d = 2; 3; are of fundamental importance in science and engineering. They are of particular relevance in the design of many engineering ... -
