Shape Optimization Using A Meshless Flow Solver And Modern Optimization Techniques
(2009-03-17)The development of a shape optimization solver using the existing Computational Fluid Dynamics (CFD) codes is taken up as topic of research in this thesis. A shape optimizer was initially developed based on Genetic ... -
Shape-constrained Biomedical Image Segmentation and Applications
The detection, segmentation, and delineation of the targeted regions of interest in biomedical images are fundamental steps for computer-aided assessment and prescreening. In this thesis, we focus on shape-constrained ... -

Shear Behaviour of GCL-Sand Interrfaces under Static and Dynamic Conditions
Geosynthetic clay liners (GCL) are unique geocomposites that combine the beneficial properties of bentonite clay and geosynthetics in providing effective hydraulic barriers in landfill systems. In landfills, GCLs form ... -
Shear Behaviour of Sand-geosynthetic Interfaces Based on Size And Morphology of Sand Particles and Surface Roughness of Geosynthetics
(2018-01-01)Geosynthetics are used in conjunction with soil/particulate materials to serve various functions like reinforcement, drainage, filtration and containment. The shear behavior of soil-geosynthetic interfaces hugely depends ... -
Shear Induced Transitions In Mixed Surfactant Systems And Anisotropic Colloids
(2017-06-12)This thesis deals with the non-equilibrium phenomena under shear observed mainly in bilayer forming liquid crystalline phases of mixed surfactant systems, anisotropic colloidal dispersions as well as Langmuir monolayers ... -
Shift-like Automorphisms of Ck
(2018-01-03)We use transcendental shift-like automorphisms of Ck, k > 2 to construct two examples of non-degenerate entire mappings with prescribed ranges. The first example exhibits an entire mapping of Ck, k>2 whose range avoids a ... -
Shock Dynamics due to Downstream Pressure Perturbations: Idealization of Transonic Unstarted Cascade Flutter
Shock wave unsteadiness is an important phenomenon in high-speed aerodynamics. This phenomenon is observed in many locations of high-speed vehicles, such as supersonic inlets, ramjet engines, transonic airfoils, high-speed ... -
Shock tube experimental and advanced computational investigations on pyrolysis of cyclohexane derivatives and C2 + C2 reaction
My thesis involves studying the pyrolysis/thermal decomposition of cyclohexane derivatives (important constituents of conventional transportation fuel). From the literature as well as the composition analysis of two fuels ... -
Shock Tube Investigation and Modeling of Dicyclopentadiene: Fundamental to Application
Dicyclopentadiene (DCPD), a homodimer of cyclopentadiene (C5H6) was chosen for the present study. DCPD can be obtained by dehydrogenation of JP-10 (jet propellant C10H16) which is currently used as aviation fuel. The ... -
Shock Tunnel Investigations on Hypersonic Impinging Shock Wave Boundary Layer Interaction
(2018-04-13)The interaction of a shock wave and boundary layer often occurs in high speed flows. For sufficiently strong shock strengths the boundary layer separates, generating shock patterns in the contiguous inviscid flow (termed ... -
Shock Tunnel Investigations On Hypersonic Separated Flows
(2009-08-11)Knowledge of flow separation is very essential for proper understanding of both external and internal aerothermodynamics of bodies. Because of unique flow features such as thick boundary layers, merged shock layers, strong ... -
Shock Wave-boundary Layer Interaction in Supersonic Flow over Compression Ramp and Forward-Facing Step
(2018-01-12)Shock wave-boundary layer interactions (SWBLIs) have been studied ex-tensively due to their practical importance in the design of high speed ve-hicles. These interactions, especially the ones leading to shock induced ... -
Shocks, Shock-Boundary Layer Interaction, And Transonic Flutter
(2017-09-27)Transonic utter is an aeroelastic instability characterized by part-chord shocks over an airfoil and single mode oscillations leading to a drop in the utter boundary. We present a numerical study that examines the influence ... -
Short Circuit and Open Circuit Natural Frequencies of 3-Φ Transformers: Derived Analytical Expressions and its Applications
Frequency Response Analysis (FRA) method is perhaps the most sensitive tool that can detect even the slightest of winding/core movements. High sensitivity, non-invasiveness, non-destructiveness, and on-site capability are ... -
Short to Medium Range Forecasting Skills of the GFS Model
The reliable prediction of the South Asian monsoon rainfall and its variability is crucial for various hydrological applications and early warning systems. This study analyzes Global Fore- cast System (GFS) model generated ... -
Shortest Length Geodesics on Closed Hyperbolic Surfaces
(2018-01-31)Given a hyperbolic surface, the set of all closed geodesics whose length is minimal form a graph on the surface, in fact a so called fat graph, which we call the systolic graph. The central question that we study in this ... -
Signal Processing Algorithms For Digital Image Forensics
(2010-03-19)Availability of digital cameras in various forms and user-friendly image editing softwares has enabled people to create and manipulate digital images easily. While image editing can be used for enhancing the quality of the ...
