Effect of Convection and Shrinkage on Solidification and Microstructure Formation
(2017-11-24)
Understanding the fundamental mechanisms of solidification and the relative significance of different parameters governing these mechanisms is of vital importance for controlling the evolution of microstructure during ...
Interaction of Bubbles with Vortical Structures
(2017-09-23)
Bubbly turbulent flows occur in a variety of industrial, naval and geophysical problems. In these flows, the bubbles in the flow interact with turbulence and/or vortical structures present in the continuous phase, resulting ...
Influence of Contact Stresses on Shape Recovery in Sputter Deposited NiTiCu Thin Films
(2017-10-05)
NiTiCu is a shape memory alloy that regains its original shape after large amount of shape changing deformation when heated above a critical temperature called reverse martensitic trans-formation temperature( Af). When ...
Geometric Reasoning with Mesh-based Shape Representation in Product Development
(2017-10-09)
Triangle meshes have become an increasingly popular shape representation. Given the ease of standardization it allows and the proliferation of devices (scanners, range images ) that capture and output shape information as ...
Specification and Verification of Tolerances for Parts with Free-Form Surfaces
(2017-11-27)
The need for increased product variety and improved aesthetics require the manufacturing enterprise to reduce time to market and to increase use of free-form surfaces in the form of the product. These changes lead to ...
Dynamics Of Cricket Song Towards Nature-inspired MEMS Speakers
(2016-09-15)
The clever designs of natural transducers are a great source of inspiration for man-made systems. At small length scales, there are many transducers in nature that we are now beginning to understand and learn from. Here, ...
Creation of an Orderly Jet and Thrust Generation in Quiescent Fluid from an Oscillating Two-dimensional Flexible Foil
(2018-02-22)
In nature, many of the flapping wings and fins in swimming and flying animals have various degrees of flexibility with strong and coupled solid-fluid interactions between the structure and the fluid. In most cases, the ...
Studies on the Design of Novel MEMS Microphones
(2018-02-17)
MEMS microphones have been a research topic for the last two and half decades. The state-of-the-art comprises surface mount MEMS microphones in laptops, mobile phones and tablets, etc. The popularity and the commercial ...
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 ...
Studies on Multiphase, Multi-scale Transport Phenomena in the Presence of Superimposed Magnetic Field
(2018-02-28)
Multiphase transport phenomena primarily encompass the fundamental principles and applications concerning the systems where overall dynamics are precept by phase change evolution. On the other hand, multiscale transport ...
