Pore Forming Toxins : Unravelling Oligomerization Pathways and Related Kinetics
Pore forming toxins are a class of proteins secreted from a wide variety of pathogens. These toxins are implicated in several diseases such as cholera, anthrax, tuberculosis and food poisoning. The toxin proteins are ... -
Motion Planning of Flexible One-dimensional Object and Hyper-redundant Robots
This thesis deals with motion planning of flexible one-dimensional objects and hyper-redundant serial robots moving in a plane or in three dimensional space. The flexible one-dimensional object is modeled as a continuous ... -
Microstructural Evolution of Directionally Solidified Ni-Al-Re/Ru Alloys
Nickel based superalloys are high temperature materials which find application as blade and disc components of jet engines due to their ability to retain their mechanical properties at temperatures close to 0.8 of their ... -
Experimental Studies on Gaseous Mixing in a Low Area Ratio Rectangular Supersonic Confined Jet
When a supersonic jet passes through a confined passage, it is called as supersonic confined jet. They are encountered in many aerospace applications such as supersonic ejectors, supersonic mixers/purgers, and thrust ... -
Numerical Modelling of Reinforced Concrete Structural Elements and Assemblages Exposed to Thermo-mechanical Loading
Fire represents one of the extreme loads that a structure may experience during its design life. In reinforced concrete (RC) structures, the mechanical properties of both concrete and steel deteriorates with rise in ... -
Effect of Surface Texture on Friction under Dry Reciprocating Contacts
Surface texture has been successfully used in many fields to improve the performance of surfaces, in applications like drag reduction, control of wettability, and enhancement of heat transfer. In tribology, surface texture ... -
Nano Surface Modifications for Anti-Corrosive and Anti-Biofouling Applications
Microbially Induced Corrosion (MIC) of materials is a major concern of marine industry. Various ferrous and non-ferrous materials used in industry are prone to MIC. Bio-fouling or formation of bio-film on material surface ... -
Design, Analysis, Simulation and Experimentation of a Flexible Spine Quadruped
Quadrupeds robots can move on uneven and rough terrain where mobile robots cannot venture. Al-though bipeds have more capabilities, they are inherently unstable and difficult to control. Most quadrupeds today are built ... -
Externally Induced Instabilities in Contactless Functional Droplets
Many natural and technological processes involve spray or cluster of droplets which are subjected to chaotic external environment. Study of the behavior of a single droplet is therefore crucial to understand the dynamics ... -
Dynamic Strain Aging and Creep in near-α Ti Alloy, IMI834
IMI 834 is a near- Ti alloy used in high temperature applications such as compressor discs and blades of aero engines. Titanium alloys including IMI 834 are known to exhibit dynamic strain aging (DSA) over the temperature ... -
Non-catalytic Synthesis of Biolubricant Esters and their Solubilities in Supercritical Fluids
Breakdown products released due to increased loss of mineral oil based lubricants to the environment lead to aquatic toxicity and release of harmful volatile compounds into the atmosphere. The production of these conventional ... -
Molecular Simulation Studies of Competing Pathways in Crystal Nucleation
Microscopic nature of nuclei and extremely fast nucleation events makes it difficult to study nucleation experimentally. Route to nucleation can be effected by different parameters such as thermodynamic conditions, uid ... -
Continuous-Curvature Path Planning Using Four Parameter Logistic Curves
Autonomous vehicles perform time and cost effective operations with minimal or no human effort and hence, have the potential to be used in civilian, commercial and military applications. Pertaining to these applications, ... -
Evaporation and Buckling Dynamics of Sessile Droplets Resting on Hydrophobic Substrates
(2018-09-04)Droplet evaporation is ubiquitous to multitude of applications such as microfluidics, surface patterning and ink-jet printing. In many of the process like food processing tiny concentrations of suspended particles may alter ... -
A Haptic Simulator for Gastrointestinal Endoscopy : Design Development and Experiments
(2018-09-04)Endoscopy is an involved clinical practice requiring considerable skill in performing the procedure. Virtual reality together with haptics offers immersive, flexible, and cost-effective platform for training in endoscopic ... -
A Non Resonant Piezoelectric Sensor for Mass, Force and Stiffness Measurements
(2018-09-04)The word piezo in greek means \to compress". Piezoelectric sensors work on the principle of direct piezoelectric effect, where a mechanical input generates a corresponding electric charge. The advantages of these sensors ... -
Stable Isotopic Composition of Rice Grain Organic Matter as an Archive of Monsoonal Climate
(2018-08-30)Rice grows in saturated soil water condition and its requirement for water is highest amongst other cereal crops. In India, the southwest monsoon wind regime brings rainfall that provides a favourable environment for rice ... -
Analytical Modelling and Non-linear Characterisation of Piezoelectric Materials for Actuation and Vibration Control of Beams
(2018-08-29)The use of piezoelectric materials for actuation, and vibration suppression of thin beams, is the subject of study in this doctoral thesis. The initial focus is set on reducing beam vibrations with resistively shunted ... -
Supporting Real-Time, Automated Evaluation of Difficulty in Manual Assembly
(2018-08-29)Product designers address the costs of assembly during the design process. Design process can be more efficient if assembly issues could be addressed early in its design process. Doing this requires the ability to assess ... -
Diffusion-Controlled Growth of Phases in Metal-Tin Systems Related to Microelectronics Packaging
(2018-08-28)The electro–mechanical connection between under bump metallization (UBM) and solder in flip–chip bonding is achieved by the formation of brittle intermetallic compounds (IMCs) during the soldering process. These IMCs ...
