Semi-active Control of Earthquake Induced Vibrations in Building Structures using MR Dampers: Algorithm Development and Benchmark Application
The thrust of this thesis is the development of two different kinds of feed-forward control strategy using the semi-active device MR damper to monitor MR damper supply current/voltage. The study develops a feed-forward ... -
Semi-active Control Of Earthquake Induced Vibrations In Structures Using MR Dampers : Algorithm Development, Experimental Verification And Benchmark Applications
(2010-08-16)As Civil Engineering structures, e.g., tall buildings, long span bridges, deep water offshore platforms, nuclear power plants, etc., have become more costly, complex and serve more critical functions, the consequences of ... -
Semiotic Studies on Holistic Order in Product Design
(2018-02-16)‘Holistic Order’ is a new term used in this study. In literature, its synonyms such as beauty, order, visual order, and aesthetic order have been in usage for a long time. Historical studies on arts & crafts from philosophical ... -
Semisolid Die Casting of Wrought A6061 Aluminium Alloy
(2018-04-02)The mechanical properties achieved with high performance wrought aluminium alloys are superior to cast aluminum alloys. To obtain an intricate shaped component, wrought alloys are commonly subjected to forging followed by ... -
Sensitivity of Sea Surface Temperature Intraseasonal Oscillation to Diurnal Atmospheric Forcings in an OGCM
(2018-04-05)Abstract The diurnal cycle is a dominant mode of sea surface temperature (SST) variability in trop-ical oceans, that influences air-sea interaction and climate processes. Diurnal variability of SST generally ranges from ... -
Shaking Table Studies on Seismic Response of Unreinforced and Geosynthetic Reinforced Soil Slopes
Experiences from recent earthquake records all over the world suggest that reinforced soil slopes provide better resistance to the seismic forces and possess higher yield accelerations compared to unreinforced slopes. ... -
Shaking Table Tests to Study the Influence of Ground Motion, Soil and Site Parameters on the Initiation of Liquefaction in Sands
(2018-01-12)Liquefaction is a phenomenon in which soil loses a large percentage of its shear resistance due to increased pore water pressure and flows like a liquid. Undrained cyclic loading conditions during earthquakes cause ... -
Shape Characterization of Granular Particles using Image Based Techniques
(2018-05-22)Granular soils with different sizes and shapes are often used in many civil engineering structures. In different contexts, several researchers have emphasized that shape of particles play a pivotal role in influencing ... -
A shape optimization approach for simulating contact of elastic membranes with rigid obstacles
The obstacle problem consists in computing equilibrium shapes of elastic membranes in contact with rigid obstacles. In addition to the displacement u of the membrane, the interface on the membrane demarcating the ... -
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 ... -
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 ... -
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 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 ... -
