Reverse Channel Training in Multiple Antenna Time Division Duplex Systems
(2018-04-02)Multiple-Input Multiple-Output (MIMO) communication using multiple antennas has received significant attention in recent years, both in the academia and industry, as they offer additional spatial dimensions for high-rate ... -
Reversible Redox Switching of First Hyperpolarizability (Β) of Metallorganic Complexes
The concept of molecular switches has garnered enormous interest because of the vital role of these switches as components in molecular electronic/photonic devices, signal transmission and optical communication. Compounds ... -
Revisiting Statistical Techniques for Result Cardinality Estimation
The Relational Database Management Systems (RDBMS) constitute the backbone of today's information-rich society, providing a congenial environment for handling enterprise data during its entire life cycle of generation, ... -
Revisiting the General Circulation of the Tropics
This thesis examines some aspects of the tropical general circulation. First, we consider the zonal momentum budget of the tropical upper troposphere. Our motivation is the zonal inhomogeneity of the Earth that presents ... -
Rheological Studies on Slow Flow in Dense Granular Ensembles
An experimental study on the rheology and kinematics of dense granular materials is presented in this thesis in the slow flow regime. In this study, we employ an often used experimental set up of the cylindrical Couette ... -
Rheology of Dense Granular Chute Flows
Granular flows have always fascinated researchers through its complex and mysterious behavior. Although a collection of solids, they exhibit properties like that of fluids. Flows over an inclined plane, known as chute flow, ... -
Rheology of dense granular materials
Granular materials are frequently encountered in our daily lives and are widely used in several industrial processes. Characterising the flow of these materials has always proved challenging due to the lack of simple ... -
Rheology of dense non-Brownian suspensions
Suspensions are ubiquitous in nature and industry, ranging from magma, blood, and mud to cement, paint, and molten chocolate. Despite the Newtonian nature of the suspending fluid and the expectation of linearity in the ... -
Ricci Flow And Isotropic Curvature
(2014-09-03)This thesis consists of two parts. In the first part, we study certain Ricci flow invariant nonnegative curvature conditions as given by B. Wilking. We begin by proving that any such nonnegative curvature implies nonnegative ... -
Rice transcription factors OsMADS2 and OsMADS4 regulate floret organ development: Deciphering their gene targets, traits and functions related to their unequal genetic redundancy
Organs in modern dicot flowers are positioned in concentric rings (whorls). The outermost whorl has green protective sepals, internal to which are showy petals, and the reproductive stamen and carpel whorls. Florets of ... -
Riemann Roch Theorem For Algebraic Curves

Riesz Transforms Associated With Heisenberg Groups And Grushin Operators
(2015-12-08)We characterise the higher order Riesz transforms on the Heisenberg group and also show that they satisfy dimension-free bounds under some assumptions on the multipliers. We also prove the boundedness of the higher order ... -
Rigidity And Regularity Of Holomorphic Mappings
(2015-07-16)We deal with two themes that are illustrative of the rigidity and regularity of holomorphic mappings. The first one concerns the regularity of continuous CR mappings between smooth pseudo convex, finite type hypersurfaces ... -
Rinderpest Virus Transcription : Functional Dissection Of Viral RNA Polymerase And Role Of Host Factor Ebp1 In Virus Multiplication
(2009-11-23)Rinderpest virus (RPV) belongs to the order Mononegavirale which comprises non segmented negative sense RNA viruses including human pathogens such as Measles, Ebola and Marburg virus. RPV is the causative agent of Rinderpest ... -
Ring Oscillator Based Temperature Sensor
(2016-06-20)The temperature sensor design discussed in this thesis, is meant mainly to monitor temperature at power outlets. Current variations in power cords have a direct impact on the surrounding temperature. Sensing these variations ... -
Risk Estimation Strategies for Speech Signal Denoising
In automatic speech recognition (ASR) systems, the recognition performance is severely affected by noise in the input speech signal [2]. One can improve the performance of ASR systems in noisy environments by denoising ... -
Risk-Sensitive Stochastic Control and Differential Games
This thesis studies risk-sensitive stochastic optimal control and differential game problems. First, we study risk-sensitive stochastic differential games for controlled reflecting diffusion processes in a smooth bounded ...
