Stability of wall-bounded compressible shear flows
In this work, the linear stability of compressible shear flows in channels and pipes are studied. A steady fully-developed laminar flow of an ideal gas, driven in a channel and a pipe by a constant body acceleration, is ... -
Stable isotope and biogeochemical study of arsenic contamination in shallow groundwater at seasonal time intervals from West Bengal (Nadia district)
Seasonal monitoring of groundwater is essential to ascertain safe water for the population and ecosystem for drinking, irrigation, domestic purposes and to keep track of groundwater quality with natural (climate change ... -
Stable isotope geochemistry of carbonatites: New insights into the petrogenesis and evolution
Carbonatites are carbonate-rich magmatic rocks that are commonly thought of having a mantle origin and are thus, of great interest to geologist for understanding the chemical evolution of the upper mantle. This thesis ... -
Stable Isotopic Composition of Rice Grain Organic Matter as an Archive of Monsoonal Climate
(2018-08-30)Rice grows in saturated soil water condition and its requirement for water is highest amongst other cereal crops. In India, the southwest monsoon wind regime brings rainfall that provides a favourable environment for rice ... -
A stable Strontium isotopic (δ88/86Sr) study of seawater from the Bay of Bengal, coastal groundwater from the Bengal Basin, and the Ganges, Brahmaputra, Mahanadi, and Godavari rivers in India
Strontium (Sr) is an alkaline earth element that has four naturally occurring stable isotopes, 84Sr, 86Sr, 87Sr and 88Sr. During measurements of the radiogenic Sr isotope ratio (87Sr/86Sr), which is a widely used tracer ... -
Stall Flutter of a Cascade of Blades at Low Reynolds Number
(2017-12-05)Due to the requirements for high blade loading, modern turbo‐machine blades operate very close to the stall regime. This can lead to flow separation with periodic shedding of vortices, which could lead to self induced ... -
Standoff Target Tracking Guidance using Line-of-Sight Distance Bifurcation
Unmanned aerial vehicle (UAV) applications that continue to receive significant attention are target acquisition and tracking. There exist many paths to track a stationary target from a prescribed altitude. The most widely ... -
State and Parameter Estimation in Water Distribution Systems
Water Distribution Systems (WDS) are one of the most important infrastructures in a society, which has a direct impact on human lives. Water authorities around the world are expected to supply the required amount of water ... -
Static and Dynamic Behavior of Reinforced Masonry : Experimental and Analytical Investigations
(2018-07-18)The most common form of dwellings in rural and semi-urban areas of India and other developing countries around the globe are one/two storey unreinforced masonry (URM) buildings. It is well known that such masonry buildings ... -
Static And Dynamic Behaviour Of Cement Stabilised Rammed Earth Panels And Building Models
(2011-01-10)Rammed earth is one of the earliest building materials used for structural walls. Stabilised rammed earth is a variant of traditional or pure rammed earth that involves addition of a small amount of cement to improve ... -
Static Balancing of Rigid-Body Linkages and Compliant Mechanisms
(2018-03-07)Static balance is the reduction or elimination of the actuating effort in quasi-static motion of a mechanical system by adding non-dissipative force interactions to the system. In recent years, there is increasing recognition ... -
Statics of Shallow Bistable Arches
Bistable arches have two force-free stable equilibrium configurations. They also show multimodality by switching between their stable states in multiple deformation pathways. These two attributes and their nonlinear ... -
Steady Sedimentation of Particles in Long Vertical Tube and Effect of End Boundary Conditions on Convective Motion
Sedimentation – settling of particles in a fluid- is observed in nature like rain droplets and dust particles in the atmosphere, and in a variety of industrial processes, like to clarify liquid as well as separate particles ... -
Steady State Dynamics Of Systems With Fractional Order Derivative Damping Models
(2011-01-10)Rubber like materials find wide applications in damping treatment of structures, vibration isolations and they appear prominently in the form of hoses in many structures such as aircraft engines. The study reported in this ... -
Stirring and mixing driven by mesoscale eddies in the stratified Bay of Bengal
The stirring of passive tracers driven by altimetry-derived daily surface geostrophic currents is studied on subseasonal timescales in the Bay of Bengal. Advection of latitudinal and longitudinal bands highlights the chaotic ... -
Stochastic Analysis Of Flow And Solute Transport In Heterogeneous Porous Media Using Perturbation Approach
(2009-04-16)Analysis of flow and solute transport problem in porous media are affected by uncertainty inbuilt both in boundary conditions and spatial variability in system parameters. The experimental investigation reveals that the ... -
Stochastic Modelling of Flexible Pavement Performance
(2017-11-16)Stochastic analysis provides a rationale for the treatment of uncertainties, founded on the principles of probability theory and statistics, and is concerned with a quantifiable measure of the confidence or the reliability ...
