The Retrieval of Aerosols above Clouds and their Radiative Impact in Tropical Oceans
(2018-03-01)Aerosols affect the global radiation budget which plays an important role in determining the state of the Earth's climate. The heterogeneous distribution of aerosols and the variety in their properties results in high ... -
Retrieval Of Dust Aerosols Using METEOSAT Infrared Radiance
(2011-05-04) -
Retrieval of Land Surface Variables using Microwave Remote Sensing
Microwave remote sensing of the land surface processes has advantages over optical remote sensing such as least attenuation due to the atmosphere, and high temporal resolution among others. Soil moisture is an important ... -
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 ... -
Robust Adaptive Control of a Laser Beam System for Static and Moving Targets
(2018-02-28)The motivation of this thesis is to propose a robust control technique for a laser beam system with target estimation. The laser beam is meant to track and fall on a particular portion of the target until the operation is ... -
Robust Finite Element Strategies for Structures, Acoustics, Electromagnetics and Magneto-hydrodynamics
(2017-12-13)The finite element method (FEM) is a widely-used numerical tool in the fields of structural dynamics, acoustics and electromagnetics. In this work, our goal is to develop robust FEM strategies for solving problems in the ... -
Robust Numerical Modeling of Adhesively-Bonded Joints for Safety Assessment of Vehicle Body Structures Subjected to Extreme Loading
Continuous adhesively-bonded joints can lead to stiffer vehicle body structures in contrast to conventional spot-welded steel sheet metal-based unitized vehicle body design. For a given target stiffness, adhesive bonding, ... -
Robust Partial Integrated Guidance And Control Of UAVs For Reactive Obstacle Avoidance
(2012-04-24)UAVs employed for low altitude jobs are more liable to collide with the urban structures on their way to the goal point. In this thesis, the problem of reactive obstacle avoidance is addressed by an innovative partial ... -
Robust Registration of Measured Point Set for Computer-Aided Inspection
(2018-03-22)This thesis addresses the problem of registering one point set with respect to another. This problem arises in the context of the use of CMM/Scanners to inspect objects especially with freeform surfaces. The tolerance ... -
Robust Station-keeping and High-Precision Attitude Control for a Spacecraft on Sun–Earth L1 Halo Orbit
The halo orbits around the Sun-Earth L1 Lagrange point form an ideal location for deploying a solar observation spacecraft as they offer uninterrupted, long-duration visibility of the Sun. However, the complex orbital and ... -
Role of Aerosols in Modulating the Intraseasonal Oscillations of Indian Summer Monsoon
(2017-12-05)In this thesis, we have presented a systematic analysis of the change of cloud properties due to variation in aerosol concentration over Indian region using satellite observations, and Weather Research and Forecasting Model ... -
Role Of Boron On The Evolution Of Microstructure And Texture In Ti-6AL-4V-0.1B Alloy
(2013-06-04)Titanium and its alloys constitute an important class of materials for aerospace, biomedical, and chemical industries, primarily due to their high specific strength and fracture toughness with good corrosion resistance. ... -
Role of Composition, Structure and Physico-Chemical Environment on Stabilisation of Kuttanad Soil
(2018-04-12)Soft soil deposits of coastal regions and lowland areas pose many geotechnical problems but it is indispensable to utilize these grounds to meet the growing demand for infrastructure with ever increasing urbanization and ...
