Space-time variability of near-surface salinity in the Bay of Bengal
Freshwater from monsoon rain and rivers leads to a 5-10 m deep low-salinity layer in the north Bay of Bengal from August to February. The thin fresh layer, with strong stratification at its base, is highly responsive to ... -
Spatial downscaling and analysis of satellite and ground-based rainfall for hydrological modelling
Precipitation is a vital element of the global hydrological and energy cycles, which is intermittent and highly variable in both space and time. Accurate measurements of precipitation at various space and time scales are ... -
Spatio-temporal characteristics of precipitating clouds and rainfall over the Western Ghats of India
One of the heaviest rainfall receiving regions during the Indian summer monsoon season is anchored around the orographic barriers of the Western Ghats (WG) in peninsular India. The high rainfall is attributed to the forced ... -
Spatio-temporal Dynamics in Droplet Combustion Under Diverse Flow Conditions
Spray combustion of liquid fuels is one of the most ubiquitous modes of combustion used in a wide range of applications ranging from IC engines for transportation to Gas turbines in propulsion systems, owing to the high ... -
Special Finite elements for analysis of pain jionts in composite plates
Joints are essential to connect various components of a structural assembly. Among various methods of joining, pin (or fastener) joints are of detachable type and are the most preferred under situations requiring periodic ... -
Specification and Verification of Tolerances for Parts with Free-Form Surfaces
(2017-11-27)The need for increased product variety and improved aesthetics require the manufacturing enterprise to reduce time to market and to increase use of free-form surfaces in the form of the product. These changes lead to ... -
Spectral Analysis of Wave Motion in Nonlocal Continuum Theories of Elasticity
Traditionally, in solid mechanics, classical continuum theories of elasticity have been an important tool in the examinations of behaviour of solids under external loads. However, due to absence of length scale information ... -
Spectral Methods for different classes of Partial Differential Equations
The thesis touches numerical solutions and wave propagation analysis using spectral methods for different classes of partial differential equations (PDEs) having applications in various fields. We address the solution of ... -
Speech Signal Classification Using Support Vector Machines
(2011-03-16)Hidden Markov Models (HMMs) are, undoubtedly, the most employed core technique for Automatic Speech Recognition (ASR). Nevertheless, we are still far from achieving high‐performance ASR systems. Some alternative approaches, ... -
Spherical Indentation Response of Bulk and Thin Film Shape Memory Alloys
Shape memory alloys (SMAs) have the ability to recover large strains upon undergoing a thermomechanical cycle. In addition to being used as structural elements, they can be patterned as thin films which can be employed in ... -
Spontaneous Crack Propagation In Functionally Graded Materials
(2009-10-28)Functionally graded materials (FGMs) are composites that have continuously varying material properties, which eliminate undesirable stress concentrations that might otherwise occur in layered composites. The concept of ... -
Spray Interaction with Supersonic Crossflow
The flow residence time in a scramjet combustor is of the order of a millisecond (10−3s). High energy density liquid fuels are the energy carriers of choice in scramjet engines, however liquid fuels must be atomized, ... -
Spray morphology and droplet characteristics in gas centered swirl coaxial (GCSC) atomizers
Studies on liquid atomization and spray formation in coaxial type atomizers are necessary to improve the performance of liquid propellant rocket engines. Recess ratio, expressed as the ratio of orifice recess length to ... -
Stabilisation Of Black Cotton Soil By Lime Piles
(Indian Institute of Science, 2006-07-07)Modification of black cotton soils by chemical admixtures is a common method for stabilizing the swell-shrink tendency of expansive soils. Advantages of chemical stabilization are that they reduce the swell-shrink tendency ... -
Stabilised Rammed Earth For Walls : Materials, Compressive Strength And Elastic Properties
(2011-01-10)Rammed earth is a technique of forming in-situ structural wall elements using rigid formwork. Advantages of rammed earth walls include flexibility in plan form, scope for adjusting strength and wall thickness, variety of ... -
Stability Numbers For Slopes With Associated And Non-Associated Flow Rule And Shake Table Liquefaction Studies
(2007-10-23)Based upon the upper bound limit analysis, the stability numbers have been developed for a two-layered soil slope both for an associated flow rule material and for a homogeneous slope with non-associated flow rule material. ... -
Stability Of Double-Diffusive Finger Convection In A Non-Linear Time Varying Background State
(2010-09-06)Convection set up in a fluid due to the presence of two components of differing diffusivities is known as double diffusive convection. Double diffusive convection is observed in nature, in oceans, in the formation of certain ... -
Stability of slopes and passive earth structures in partially saturated soils by the method of characteristics.
Stability analysis of slopes and passive earth pressures are problems of considerable economic importance and technical interest in geotechnical engineering. Efforts have continuously been made to improve the methods of ... -
Stability of unbounded and bounded granular shear flows
Recent computer simulations of granular flows (Hopkins & Louge 1991; Goldhirsch, Kui & Zanetti 1993) have identified an interesting picture of cluster formation. In this thesis, we have attempted to explain particle ...
