(2018-06-05)Flapping-wing micro air vehicle (MAV) is an emerging micro-robotic technology, which has several challenges toward its practical implementation. Inspired by insect flight, researchers have adopted bio-mimicking approach ... -
Vulnerability of Forests to Climatic and Non-Climatic Stressors : A Multi-Scale Assessment for Indian Forests
(2018-06-05)During the 21st century, climatic change and non-climatic stressors are likely to impact forests leading to large-scale forest and biodiversity loss, and diminished ecological benefits. Assessing the vulnerability of ... -
Bioremediation of Chromium : Mechanisms and Biosensing Applications
(2018-06-05)Water pollution, especially caused due to the indiscriminate release of heavy metals as a result of anthropogenic activities is a major concern worldwide. Chromium, a heavy metal, regardless of its commercial importance ... -
Impact Angle Constrained Guidance Using Cubic Splines
(2018-06-05)In this thesis the cubic spline guidance law and its variants are derived. A detailed analysis is carried out to find the initial conditions for successful interception. The results are applied to three dimensional ... -
Large Eddy Simulation of Multiphase Flows
(2018-06-05)Multiphase flows are a common phenomenon. Rains, sediment transport in rivers, snow and dust storms, mud slides and avalanches are examples of multiphase flows occurring in nature. Blood flow is an example of multiphase flow ... -
Modeling of the Haltere-A Natural Micro-Scale Vibratory Gyroscope
(2018-06-05)Vibratory gyroscopes have gained immense popularity in the microsystem technology because of their suitability to planar fabrication techniques. With considerable effort in design and fabrication, MEMS (Micro-electro-mec ... -
Quantitative Laser-Based Diagnostics and Modelling of Syngas-Air Counterflow Diffusion Flames
(2018-06-05)Syngas, a gaseous mixture of H2, CO and diluents such as N2, CO2, is a clean fuel generated via gasification of coal or biomass. Syngas produced via gasification typically has low calorific values due to very high dilution ... -
Elastic Wave Propagation and Evaluation of Low Strain Dynamic Properties in Jointed Rocks
(2018-06-05)When the point under consideration is not near to the source of vibration, the strains developed in the rock mass due to the passage of waves are usually of small magnitude, and within the elastic range. However, the rock ... -
Design and Fabrication of Conjugated Molecule Based Resistive Sensor for Environmental Monitoring Detecting Targeted Analytes
(2018-06-05)Volatile organic compounds (VOCs) in air and heavy metal ions, anions, microorganism in water are environmental contaminants that require detection at certain low concentrations to avoid detrimental effects. Analytical ... -
Numerical Modelling and Software Development for Analysing Squeeze Film Fffect in MEMS
(2018-06-05)The goal of the current study was to develop a computational framework for modelling the coupled fluid-structure interaction problem of squeeze films often encountered in MEMS devices. Vibratory MEMS devices such as ... -
Effect of Humidity and Temperature on Wear of TiN and TiAIN Coatings
(2018-05-30)When loss of material due to sliding of two solids is promoted/prevented, in the presence of chemically reacting liquid or gas, tribochemical wear is said to occur. Tribochemical wear, in which corrosive media promotes ... -
Time-Optimal Guidance for Impact Angle Constrained Interception of Moving Targets
(2018-05-30)Various unmanned missions deploy vehicles such as missiles, torpedoes, ground robots, and unmanned aerial vehicles. Guidance strategies for these vehicles aim to intercept a target point and satisfy additional objectives ... -
Studies on the Effect of Process Aspects on Material Mixing and Defect Formation in Friction Stir Welding
(2018-05-30)Friction Stir Welding (FSW) is a rapidly growing solid state welding process and has been a proven method for welding high strength aluminium alloys which were formerly not recommended for joining by conventional fusion ... -
Edge Effect of Semi-Infinite Rectangular Posts on Impacting Drops
(2018-05-30)The inhibiting effect of a sharp edge on liquid spreading is well observed during drop interaction with textured surfaces. On groove-textured solid surfaces comprising unidirectional parallel grooves, the edge effect of ... -

(2018-05-30)Natural turbulent convection studies encompass a wide range of flows occurring in nature, for example, atmospheric and oceanic flows, con-vection in the Earth’s mantle, convection in the stars and also in many engineering ... -
Unraveling the Evolutionary Advantages of Crosstalk Between Two-Component Signalling Systems of M tuberculosis
(2018-05-29)M. tuberculosis (Mtb) senses and responds to changes in its environment primar-ily through two-component signalling systems (TCSs). Each TCS contains a trans-membrane histidine kinase (HK ) protein and a cytoplasmic response ... -
Intent- driven Correspondence and Registration of Shapes
(2018-05-29)Registration means to bring two or more shapes into a suitable relative configuration (position and orientation). In its major applications like 3D scan alignment, the aim is to coalesce data and regions originating from ... -
Estimation of Stress Concentration and Stress Intensity Factors by a Semi-Analytical Method
(2018-05-29)The presence of notches or cracks causes stresses to amplify in nearby regions. This phenomenon is studied by estimating the Stress Concentration Factor (SCF) for notches, and the Stress Intensity Factor (SIF) for cracks. ... -
