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 ...
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 ...
Fabrication and Characterization of Optomechanical Devices
Silicon photonics is a promising platform for photonic devices and circuits, largely driven by advanced complementary metal-oxide-semiconductor (CMOS) processing technology. An extremely crucial component for a photonic ...
Kinematic Design and Optimal Synthesis of Parallel Manipulators Using Monte Carlo Method
Parallel manipulators are widely used for a variety of tasks where increased accuracy and large load carrying capacities are required. In this work, we propose a Monte Carlo based method to represent and quantify the ...
Gust Rejection in Insect Flight
Large commercial and military aircraft can fly in turbulent wind conditions except in extreme weather events like cyclones. Smaller man-made vehicles like Micro aerial vehicles (MAVs) and Nano aerial vehicles (NAVs) are ...
Continuum Analysis of Cavitation Induced Failure and Tensile Deformation Response of Metallic Glasses & Nanoglasses
Metallic glasses (MGs), which are metals solidified in an amorphous state, have shown attractive
mechanical properties such as high strength (up to 5 GPa), yield strain (around
2%) and good corrosion resistance. They ...
Simulation and Study of Noise Generated due to Turbulent Boundary Layer in Towed Hydrophone Array
In this thesis, a wave propagation based analytical model is developed for an underwater towed array. The towed array is modeled as an in finite tube filled with a certain liquid and submerged in an in finite volume of ...
Turbulent Free Convection Over Horizontal Surfaces
This thesis deals with turbulent free convection in a horizontal fluid layer above a heated
surface. The work can be roughly divided into two parts. In the &st part a model
is proposed for the near wall dynamics in ...
