Design Flood Estimation at Ungauged Locations using Geomorphological Characteristics
Estimates of design flood are necessary at locations of hydrologic structures (e.g., flood control dams, barrages) in studies related to their planning, design and risk assessment. In situations, where failure of hydrologic ... -
Design of Curved Aggressive Annular Diffusers
For economical air transportation, aero engines with lower specific fuel consumption, lower emissions and lower noise levels are required. To this end, the use of turbofan engine with high bypass ratio is an option. With ... -
Design of Planar Supersonic Wind Tunnel Nozzle
This thesis revisits the design of a planar supersonic nozzle for a supersonic wind tunnel using the method of characteristics (MOC) and Computational Fluid Dynamics (CFD). While design of a converging-diverging (CD) ... -
Design Of Two-Axis Displacement-Amplifying Compliant Mechanisms Using Topology Optimization
(2010-07-14)This thesis deals with the design of two-axis displacement-amplifying compliant mechanisms (DaCMs) using topology optimization. The two-axis compliant mechanisms considered here are XY positioners and two-axis inertial ... -
A Design Procedure for Flapping Wings Comprising Piezoelectric Actuators, Driver Circuit, and a Compliant Mechanism
(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 ... -
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 ... -
Design, Control and Experimental Validation of a Robust Adaptive Feedback Linearization Controller for a Quadcopter Manipulator System
A quadcopter manipulator system (QMS) is an aerial robot comprising a quadcopter with a three degree of freedom manipulator mounted at the bottom of the vehicle. An aerial robot can reach otherwise inaccessible ... -
Design, Development And Flight Control Of Sapthami - A Fixed Wing Micro Air Vehicle
(2010-09-21)Two micro air vehicles, namely Sapthami and Sapthami-flyer, are developed in this thesis. Their total weight is less than 200grams each. They fit inside a 30cm and 32cm sphere respectively and carry the commercially available ... -
Design, Fabrication and Application of In situ Total Internal Reflection (TIR) Raman Tribometer For the Chemical Analysis of Tribological Systems
In conventional tribological experiments that study friction and wear behavior of materials, the contact interface is hidden by the contacting bodies. The physical or chemical phenomena taking place at the interface must ... -
