Studies On The Dynamics And Stability Of Bicycles
(2009-02-25)This thesis studies the dynamics and stability of some bicycles. The dynamics of idealized bicycles is of interest due to complexities associated with the behaviour of this seemingly simple machine. It is also useful as ... -
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 ... -
Studies On Transport Phenomena During Solidification In Presence Of Electromagnetic Stirring
(2010-07-20)In several applications of casting, dendritic microstructure is not desirable as it results in poor mechanical properties. Enhancing the fluid flow in the mushy zone by stirring is one of the means to suppress this dendritic ... -
Studies on Two-Stage Air-Cooled Silica gel + Water Adsorption Cooling System
Adsorption cooling systems are evolving as promising complements to conventional vapor compression refrigeration (VCR) systems because of their ability to utilize low-grade heat sources such as industrial waste heat, solar, ... -
Study of Droplet Dynamics in Heated Environment
(2018-04-02)Droplets as precursor are extensively applied in diverse fields of science and engineering. Various contributions are provided previously towards analysis of single phase and multi-phase droplets of single and multiple ... -
A Study Of Four Nonlinear Systems With Parametric Forcing
(2010-06-01)This thesis considers four nonlinear systems with parametric forcing. The first problem involves an inverted pendulum with asymmetric elastic restraints subjected to harmonic vertical base excitation. On linearizing ... -
A Study Of Four Problems In Nonlinear Vibrations via The Method Of Multiple Scales
(2010-12-03)This thesis involves the study of four problems in the area of nonlinear vibrations, using the asymptotic method of multiple scales(MMS). Accordingly, it consists of four sequentially arranged parts. In the first part ... -
Study Of Liquid Fuel Film Transport And Its Effect On Cold Start Hydrocarbon Emissions In A Carburetted Engine
(2013-01-31)The present work is concerned with fundamental studies on the liquid fuel transport in the intake manifold of small carburetted engines. This work is motivated by the need for development of technologies to meet the stringent ... -
A Study of Mode Dependent Energy Dissipation in 2D MEMS Resonators
(2018-02-25)With the advent of micro and nano electromechanical systems (MEMS/NEMS), there has been rapid development in the design and fabrication of sensitive resonant sensors. Sensitivity of such devices depends on the resonant ... -
Study Of Multiple Asperity Sliding Contacts
(2016-06-18)Surfaces are rough, unless special care is taken to make them atomically smooth. Roughness exists at all scales, and any surface-producing operation affects the roughness in certain degrees, specific to the production ... -
Study Of Solidification And Microstructure Produced By Cooling Slope Method
(2016-05-05)In most casting applications, dendritic microstructure morphology is not desired because it leads to poor mechanical properties. Forced convection causing sufficient shearing in the mushy zone of the partially solidified ... -
Study Of Squeeze Film Effects In Modelling Dynamic MEMS Devices
(2011-02-21)We present studies on squeeze film effects in dynamic MEMS devices with a special emphasis on the development of compact analytical models. First, the efficacy of lumped parameter modelling of dynamic MEMS devices is ... -
Study Of Stall Flutter Of An Isolated Blade In A Low Reynolds Number Incompressible Flow
(2015-07-08)Highly-loaded turbomachine blades can stall under off-design conditions. In this regime, the flow can separate close to the leading edge of the blade in a periodic manner that can lead to blade vibrations, commonly referred ... -
Study Of The Effect Of Elasticity Of The Added Mass In Mass Sensing Using Resonant Peak Shift Technique
(2013-05-21)Micromachined biosensors are used in chemical and biological applications. A biosensor which uses mass based transduction is called a mass sensor. Mass sensors are used to detect extremely small mass of biomolecules such ... -
