ADVANCES IN MICRO-MANUFACTURING APPLYING TRIBOLOGICAL PRINCIPLES
(2010)Micro-manufacturing is a cover term for manufacturing processes applied to products possessing micro- and nano-scopic features. Due to the scaling of surface phenomena, the tribological aspects of such processes are much ... -
The driven cavity flow over the whole range of the Knudsen number
(2005)The flow of a rarefied gas in a rectangular enclosure due to the motion of the upper wall is solved over the whole range of the Knudsen number. The formulation is based on the two-dimensional linearized Bhatnagar-Gross-Krook ... -
Gas flow and heat transfer simulation in MEMS via a mesoscopic approach
(2004)The flow problem of binary gaseous mixtures in rectangular micro channels due to small pressure, temperature and molar concentration gradients over the whole range of the Kn number is solved. The solution is based on a ... -
Multichannel speech enhancement using MEMS microphones
(2015)In this work, we investigate the efficacy of Micro Electro-Mechanical System (MEMS) microphones, a newly developed technology of very compact sensors, for multichannel speech enhancement. Experiments are conducted on real ... -
Rarefied gas flow of binary mixtures through long channels with triangular and trapezoidal cross sections
(2010)The flow of binary gas mixtures through long micro-channels with triangular and trapezoidal cross sections is investigated in the whole range of the Knudsen number. The flow is driven by pressure and concentration gradients. ... -
Shear driven micro-flows of gaseous mixtures
(2006)A mesoscale kinetic-type approach is proposed to solve shear driven micro flows of binary gas mixtures in MEMS. The coupled linear integro-differential equations, which formally describe the flow, are solved using the ... -
Size effects on strength, toughness and fatigue crack growth of gradient elastic solids
(2008)The present study investigates the microstructural size effect on the strength of a bar under axial loading, and on the toughness and crack growth of a beam under three-point bending within the framework of strain gradient ... -
Variance-reduced DSMC for binary gas flows as defined by the McCormack kinetic model
(2012)A variance-reduced direct simulation Monte Carlo method is presented for binary gas flows as defined by the McCormack kinetic model. Two types of flow configuration, namely pressure driven flow between two parallel plates ...
