Flutter Susceptibility Assessment of Airplanes in Sub-critical Regime using Ameliorated Flutter Margin and Neural Network Based Methods
(2018-02-17)As flight flutter testing on an airplane progresses to high dynamic pressures and high Mach number region, it becomes very difficult for engineers to predict the level of the remaining stability in a flutter-prone mode and ... -
Studies on Bioremediation of Cr (VI) using Indigenous Bacterial Strains Isolated from a Chromite Mine
(2018-02-16)Heavy metals are released into the environment either by natural processes or by anthropogenic activities. Industries such as leather tanning, textiles, metallurgical, electroplating and mining activities discharge the ... -
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 ... -
Molecular Simulation of Anisotropic Stress and Structure in polymers
(2018-02-15)This dissertation presents a numerical study using molecular dynamic simulations that interrogates the polymer structure as it is strained continuously in time and correlates it with the stress developed in it. We investigate ... -
Microgravity Flow Transients in the Context of On-Board Propellant Gauging
(2018-02-15)It is well known that surface tension of a liquid has a decisive role in flow dynamics and the eventual equilibrium state, especially in confined flows under low gravity conditions and also in free surface flows. One such ... -
Cyclic Pursuit : Variants and Applications
(2018-02-11)The classical n-bugs problem has attracted considerable attention from researchers. This problem stems from the study of movement of a group of animals. In the context of multi- agent systems the problem has been modelled ... -
Seismic Hazard Assessment of Tripura and Mizoram States along with Microzonation of Agartala and Aizawl Cities
(2018-02-10)Tee present research focuses on seismic hazard studies for the states of Tripura and Mizoram in the North-East India with taking into account the complex sesismotectonic characteristics of the region. This area is more ... -
Prediction of Physical Behavior of Rotating Blades under Tip-Rub Impact using Numerical Modeling
(2018-02-09)Rotating blades, which are the most critical components of any turbo-machinery, need to be designed to withstand forced vibrations due to accidental tip rub impact against inner surface of casing. These vibrations are ... -
Theoretical Studies of the Mechanisms of the Entry of Virus into Cells
(2018-02-09)Viruses cause human diseases by entering in to human cells. Many drugs have been developed that act at various stages of viral infection, but they fail due to their toxic side effects and high mutation rates of viruses. ... -
Estimation of Root Zone Soil Hydraulic Properties by Inversion of a Crop Model using Ground or Microwave Remote Sensing Observations
(2018-02-09)Good estimates of soil hydraulic parameters and their distribution in a catchment is essential for crop and hydrological models. Measurements of soil properties by experimental methods are expensive and often time consuming, ... -
Methods on Probabilistic Structural Vibration using Stochastic Finite Element Framework
(2018-02-07)Analysis of vibration of systems with uncertainty in material properties under the influence of a random forcing function is an active area of research. Especially the characterization based on mode shapes and frequencies ... -
Experimental and Numerical Studies on Spray in Crossflow
(2018-02-06)The phenomenon of spray in crossflow is of relevance in gas turbine combustor development. The current work focuses on spray in crossflow rather than liquid jet in crossflow from the standpoint of enhancing fuel dispersion ... -
Synthesis and Characterization of Functionalized Electroactive Polymers for Metal Ion Sensing
