Analysis And Design Of Spatial Manipulators : An Exact Algebraic Approach Using Dual Numbers And Symbolic Computation
(2008-11-03)This thesis presents a unified framework for the analysis of instantaneous kinematics and statics of spatial manipulators. The proposed formulation covers the entire range of kinematic behavior, with kinematic singularity ... -
Analysis and Modelling of Small Scale Organic Rankine Cycle System with Scroll Expander
In recent years, the growing concern about pollution from fossil fuels has resulted in an increased effort for utilization of low-grade heat sources such as industrial waste heat, solar energy and other renewable sources. ... -
Analysis Of Multiply-Connected Acoustic Filters with Application To Design Of Combination Mufflers And Underwater Noise Control Linings
(2008-10-01)This thesis endeavors towards developing various concepts employed in analysis and design of acoustic filters for varied applications ranging from combination mufflers for automobiles to complex networks of gas carrying ... -
Analysis Of Non-Hertzian Contact Between Rough Surfaces

Analysis Of Squeeze Film Damping In Microdevices
(2012-12-12)There are various energy dissipation mechanisms that affect the dynamic response of microstructures used in MEMS devices. A cumulative effect of such losses is captured by an important characteristic of the structure called ... -
Analysis of Transcritical CO2 and CO2+ Propane Mixtures for Tropical Cooling Applications
The increasing global average ambient temperatures coupled with stringent environmental regulations has turned the focus on natural working fluids such as Carbon dioxide (CO2), and hydrocarbons for use in the refrigeration ... -
Analytical Investigations on Linear And Nonlinear Wave Propagation in Structural-acoustic Waveguides
(2017-09-26)This thesis has two parts: In the first part, we study the dispersion characteristics of structural-acoustic waveguides by obtaining closed-form solutions for the coupled wave numbers. Two representative systems are ... -
Analytical, Numerical, And Experimental Studies Of Fluid Damping In MEMS Devices
(2009-09-11)Fluid damping arising from squeeze film flow of air or some inert gas trapped between an oscillating micro mechanical structure, such as a beam or a plate, and a fixed substrate often dominates the other energy dissipation ... -
Asymptotic Analysis Of The Dispersion Characteristics Of Structural Acoustic Waveguides
(2010-04-12)In this work, we study the coupled dispersion characteristics of three distinct structural-acoustic waveguides, namely: -(1) a two-dimensional waveguide, (2) a fluid-filled circular cylindrical shell and (3)a fluid-filledelliptic ... -
Axially Homogeneous Turbulent Convection at High Rayleigh Numbers : Scaling Laws for Flux and Spectra
(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 ... -

Blade Flutter in a Linear Cascade: Unsteady Loads and Flow Features in Subsonic and Transonic Flows
Vibration related issues like flutter can significantly limit the performance of aircraft engines and cause unwarranted cost and time overruns. The increased demand for more powerful yet compact engines has resulted in the ... -
Blast Loading on Plain and Perforated Tubes with High Explosives
According to the assessments of the United Nations, there are more than 100 million mines lying buried in various conflict zones of many countries in the world. As per their assessment, many thousand casualties happen ... -
Breakout Noise From The Coupled Acoustic-Structural HVAC Systems
(2010-07-19)Noise control in the heating, ventilation and air-conditioning (HVAC) systems is one of the critical design parameters in measuring the occupant comfort. The noise generated by air-handling units propagates through the ... -
