Role of Gypsum in Stabilisation of Expansive Soil with Lime/Fly Ash-A Micro-Mechanistic Study
Stabilization of expansive soils with various calcium–based stabilizers (lime and cement) directly or in combinations with other solid waste materials such as fly ash and ground granulated blast furnace slag (GGBS) etc. ... -
Role Of Hydrogen Injection Temperature On The Combustion Instability Of Cryogenic Rocket Engine
(2014-04-16)Physical mechanism for high frequency instability in cryogenic engines at low hydrogen injection temperature has been a subject of debate for long time. Experimental and early developmental studies revealed no instabilities ... -
Role of in-phase octahedral tilt influencing structure and properties in Na0.5Bi0.5TiO3 - based piezoceramics
High performance perovskite (ABO3) based piezoceramics are used as actuators, pressure sensors, and transducers in wide-ranging applications spanning sectors like health, space, defence and automobiles. For over four ... -
Role Of Interfacial Phenomena In Bioprocessing Of Minerals Using Bacillus Polymyxa
(Indian Institute of Science, 2006-12-11)In recent years there has been growing interest in bio-mineral processing due to its low operating costs and its application in processing lean-grade ores. Bioprocessing is a good alternative to conventional hydrometallurgy ... -
Role of Microstructure in the Mechanics of Soft Matter
(2018-07-16)Materials which exhibit non-linear mechanical behaviors under large deformations are generally classified as “soft matter”. Elastomers represent an important class of soft materials which have wide commercial applications ... -
Role Of Mixed Convection In Cooling Of Electronics
(2011-03-15)Cooling of electronic components is one of the most important issues concerned in the electronic industry for design of equipment. Maintaining the temperature of an electronic device within its safe operating temperature ... -
Role of Physico-chemical Processes And Micro-structural Features in Influencing Moisture Loss and Engineering Properties Of Compacted Residual Soils Exposed To Environmental Relative Humidity
The moisture content of residual soils above the water table, and near ground surface (≤ 6 m) is influenced by the environmental relative humidity (RH). The focus of this thesis is to examine the physico-chemical and ... -
The role of polymer phase on rigidity percolation of ABS−spherical nickel microparticles composites
Percolation and rigidity transitions are very important phenomena in random heterogeneous microstructures, as various physical properties change abruptly at some critical volume fractions of one phase. The concepts of ... -
Role Of Sea Surface Temperature Gradient In Intraseasonal Oscillation Of Convection In An Aquaplanet Model
(2016-11-15)In this thesis we examine intra-seasonal oscillations (ISO) in the aqua-planet setup of the Community Atmospheric Model (CAM) version 5.1, mainly based on July and January climatological sea surface temperature (SST). We ... -
The Role of Self-Recirculating Casing Treatment on Axial Compressor and Its Aeroelastic Behavior
The modern-day axial compressor stages in a gas turbine engine play a vital role in generating the high-pressure ratios by operating at the limits of their design. Aerodynamic instabilities such as rotating stall and surge ... -
Role Of Solid Phase Movement And Remelting On Macrosegregation And Microstructure Formation In Solidificaiton Processing
(2010-08-25)Melt convection and solid phase movement play an important role in solidification processes, which significantly influence the formation of grain structures and solute segregations. In general, the melt convection and grain ... -
Role Of Stacking Fault Energy On Texture Evolution In Micro- And Nano-Crystalline Nickel-Cobalt Alloys
(2017-05-24)Plastic deformation of metals and alloys are invariably accompanied by the development of texture. The origin of texture is attributed to the deformation micro-mechanisms associated with processing. The face-centered cubic ... -
Rotational Temperature Measurement in Hypersonic Shock Tunnel using Tunable Diode Laser Absorption Spectroscopy
Atmospheric entry of a spacecraft is considered as one of the critical phases in any planetary mission. Although it lasts only for a few minutes, rapid heating and deceleration can cause severe problems to the spacecraft. ... -
Rotationally Invariant Kinetic Upwind Method (KUMARI)
(2009-03-11)In the quest for a high fidelity numerical scheme for CFD it is necessary to satisfy demands on accuracy, conservation, positivity and upwinding. Recently the requirement of rotational invariance has been added to this ... -
Satellite Attitude Determination from Terrestrial/Planetary Landmarks
Attitude Determination (AD) or specifying orientation relative to a known reference frame plays a crucial role in meeting the mission specific pointing goals of a satellite. Attitude sensors provide measurements of known ... -
Scaling Characteristics Of Tropical Rainfall
(2016-11-15)We study the space-time characteristics of global tropical rainfall. The data used is from the Tropical Rainfall Measuring Mission (TRMM) and spans the years 2000-2009. Using anomaly fields constructed by removing a single ... -
