Dynamically isotropic Gough-Stewart platform for micro-vibration isolation in spacecraft
Rotating components such as reaction wheels and momentum wheels on spacecraft generate micro-vibrations up to 250 Hz during on-orbit operations. While the use of Gough-Stewart Platforms (GSPs) for six degrees of freedom ... -
Dynamics and Organization of Passive and Magnetically Driven Colloids Under Optical Confinement
The physics of confined systems of interacting particles has been a subject of active research for more than a century. Such systems are ubiquitous in nature - examples include petroleum in porous rocks, cytoplasm in ... -
Dynamics and Rheology of Non-colloidal Suspensions: Active and Soft Deformable Particles
Classical works on the suspensions of rigid spherical and ellipsoidal particles have been carried out by Einstein and Jeffery. However, in nature and industry, we come across materials that are either deformable or active. ... -
Dynamics And Stability Of A Launch Vehicle
(2011-07-08)Stability is an important criterion in the design and performance of launch vehicles. Present day launch vehicles have become more and more flexible due to the constraints of weight reduction, necessarily imposed for ... -
Dynamics and Stability of Multiple Jets in Geophysical Flows
(2018-04-18)The effect of rotation on the stability of multiple jets in planetary atmospheres is system- atically investigated. Typically in Jovian planetary atmospheres, multiple zonal jets have been observed and their morphology has ... -
Dynamics and Transport Properties in Polymer Nanocomposites: Role of Interfacial Entropic and Enthalpic Effects
Polymers embedded with nanoparticles polymer nanocomposites (PNCs) have emerged as a new class of hybrid materials, which combine the unique electronic, mechanical, magnetic, catalytic, and optical properties of nanoparticles ... -
Dynamics in complex systems: liquid crystals, biological water, supercooled water and enzymes
The origin of the glassy orientational dynamics, both single particle and collective, of nematogens near the isotropic-nematic transition has been addressed in several publications in recent years [5-7, 12]. In these ... -
Dynamics of a Stratified Population of Optimum Seeking Agents on a Network
Very large scale multi-agent systems occur both naturally and in engineering applications. In many of these systems, the agents are either selfish or act with varying levels of coordination. Understanding the evolution of ... -
Dynamics of a Suspended Microchannel Resonator
Micro-Electro-Mechanical-System (MEMS) mass sensing devices have a wide variety of applications in healthcare diagnostics and biosciences. Typically, mass sensing on a MEMS device works by physisorption and chemisorption ... -
Dynamics Of Activated Processes Involving Chain Molecules
(2009-09-11)This thesis presents our recent study of few interesting problems involving activated processes. This chapter gives an overview of the thesis. It is now possible to do single molecule experiments involving enzyme molecules. ... -
Dynamics of Actuated and Interacting Swirl Premixed Flames in Model Gas Turbine Combustors
Lean premixed combustion is preferred in gas turbines because of the reduced (NOx) emissions. However, the combustors operating in lean premixed regime could suffer from problems like flame flashback, flame blowoff and ... -
Dynamics of bond-formation in some diatomics
An understanding of molecular formation from the separated atoms is one of the important goals in quantum chemistry. Earlier interpretations of the bond formation are based on the spatial characteristics of the charge ... -
Dynamics of Bubbles and Drops in the Presence of an Electric Field
(2018-07-16)The present thesis deals with two-phase electrohydrodynamic simulations of bubble and droplet dynamics under externally applied electric fields. We used the Coupled Level-Set and Volume-of-fluid method (CLSVOF) and two ... -
Dynamics Of Cricket Song Towards Nature-inspired MEMS Speakers
(2016-09-15)The clever designs of natural transducers are a great source of inspiration for man-made systems. At small length scales, there are many transducers in nature that we are now beginning to understand and learn from. Here, ... -
Dynamics of Droplets Under Support, Acoustic And/Or Ambient Flow Excitation
(2018-04-24)The first step on the way to understanding the complicated dynamics of spray is to study the behavior of isolated droplets. In many industrial and natural processes such as turbulent combustion, agricultural sprays, spray ... -
Dynamics Of Early Stages Of Transition In A Laminar Separation Bubble
(2010-04-12)This is an experimental and theoretical study of a laminar separation bubble and the associated transition dynamics in its early stages. The separation of a laminar boundary layer from a solid surface is prevalent in very ... -
