Structural acoustics of perforated panels
In this work, radiation and transmission of sound through flexible perforated panels set in infinite rigid baffles are investigated. The treatment is largely analytical using Fourier transforms and contour integrations. ...
Characterization of Corneal Lens of Drosophila melanogaster and its Genetic Mutants using Atomic Force Microscope and Scanning Electron Microscope
Drosophila melanogaster (the fruit fly) is a widely used model organism for the study of human disease condition and genetic pathways due to the high degree of gene conservation between fly and human. The compound eyes of ...
Spherical Indentation Response of Bulk and Thin Film Shape Memory Alloys
Shape memory alloys (SMAs) have the ability to recover large strains upon undergoing a thermomechanical cycle. In addition to being used as structural elements, they can be patterned as thin films which can be employed in ...
Vapor Mediated Interaction in Droplets
Controlling internal flow in evaporating sessile droplets is desirable across applications ranging from lab-on-chip medical diagnostics, DNA profiling to surface patterning. Diffusion-limited evaporation in droplets exhibits ...
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 ...
Numerical and Experimental Investigation of Mixed-mode Fracture Behavior of Basal Textured Magnesium Alloys
Magnesium alloys are finding tremendous applications in automobile and aerospace industries owing to their low density, high specific strength, good machinability and damping characteristics. However, their structural ...
Measuring Three-dimensional Deformations of Elastic Ribbons
Experimental techniques to measure and visualize kinematics in structural
and solid mechanics range from humble strain gage rosettes to sophisticated
digital image correlation methods. This thesis develops a stereo ...
Supercritical CO2 Power Cycles and Turbomachinery Development for Renewable Energy and Waste Heat Recovery
Supercritical carbon dioxide (sCO2) power cycles have transitioned from the kilowatt level pilot facilities to the megawatt level demonstration plants. Theoretical studies and commercial benefits associated with sCO2, such ...
Steady Sedimentation of Particles in Long Vertical Tube and Effect of End Boundary Conditions on Convective Motion
Sedimentation – settling of particles in a fluid- is observed in nature like rain droplets and dust particles in the atmosphere, and in a variety of industrial processes, like to clarify liquid as well as separate particles ...
Mechanics of collective cell migration on substrates of different stiffness
Collective cell migration is characteristic in many physiological processes such as wound closure, morphogenesis, and cancer tumour metastasis. Experiments on cell monolayers demonstrated the formation of finger-like ...
