Experimental Characterization Of Femtosecond Laser Micromachining For Silicon Mold Fabrication And Hot Embossing For Polymer Microreplication
(Mechanical Engineering, 2007-08-23)
Hot embossing is a fabrication technique employed for replicating microfeatures on a polymer surface that was primarily developed to fabricate MEMS devices for microfluidic applications. This manuscript deals with ...
Design And Implementation Of A Feedback Linearizing Controller And Kalman Filter For A Magnetic Levitation System
(Mechanical Engineering, 2007-08-23)
The principal investigation undertaken in this research is the development and subsequent implementation of a feedback linearizing nonlinear controller and extended Kalman filter for a laboratory-based Magnetic Levitation ...
Analysis And Design Of A Piezoelectric Micro-actuator
(Mechanical Engineering, 2007-08-23)
Micro-grippers are usually fabricated of silicon using traditional semiconductor manufacturing processes and actuated based on thermal energy input causing their temperature to substantially increase and render unsuitable ...
Numerical Study On Capillarity- Dominant Free Surface And Interfacial Flows
(Mechanical Engineering, 2007-08-23)
The continuum surface force (CSF) method has been extensively employed in the volume-of-fluid (VOF), level set (LS) and front tracking methods to model surface tension forces. Its ability is limited for the surface tension ...
Spreading, Solidification And Remelting Behavior Of Liquid Metal Droplets Sequentially Impinging Onto A Metal Substrate
(Mechanical Engineering, 2007-08-23)
The fluid dynamics and simultaneous solidification of two successive molten metal droplets impacting a flat substrate is investigated numerically. The primary objective is to investigate the effects of initial droplet and ...
Structural Optimization Using ANSYS And Regulated Multiquadric Response Surface Model
(Mechanical Engineering, 2007-08-23)
The high computational expense of large non-linear and complex finite element analysis limits or often prohibits the use of conventional codes in engineering design and multidisciplinary optimization. Consequently alternate ...
