A low-power/low-noise readout circuit for integrated capacitive sensors
(2006)A switched-capacitor integrated system is presented in this work that attains sub-fF measurement resolution in integrated capacitive sensors, with 1.5-kHz bandwidth and 50-mu W average power consumption in continuous ... -
Modelling of microstructure evolution during precipitation processes: a population balance approach of the KWN model
(2006)In the present study a general kinetic model for phase transformations resulting in a second-phase particle precipitation in a matrix is presented. Such transformations involve simultaneous nucleation, growth and coarsening ... -
Molecular dynamics simulation of the atomic structure of a NiO tilt grain boundary at high temperature
(2000)The detailed atomic structure of the Sigma 5(310)[001] tilt grain boundary is still the subject of controversy since the structures deduced from high-resolution electron microscopy (HREM) experiments differ from those ... -
Nanocrystalline growth and diagnostics of TiC and TiB2 hard coatings by pulsed laser deposition
(1999)Nanocrystalline coatings of TiC and TiB2 were grown by pulsed laser deposition on Si(100) and on X155 steel at low substrate temperatures ranging from 40 degrees C to 650 degrees C. A pulsed KrF excimer laser was used with ... -
Numerical modeling of pyrolytic laser-induced chemical vapor deposition
(2003)Laser chemical vapor deposition (LCVD) is a technique to deposit thin films of oxidation, corrosion, and wear resistant as well as electronic, optoelectronic, and superconductor materials. In order to understand the ... -
Parameters Affecting Slip Length at the Nanoscale
(2013)We investigate liquid flows in various nanochannels and present the effect of all physical parameters affecting slip length at the boundary using molecular dynamics simulations. Our computational model shows that slip ... -
Pressure driven rarefied gas flow through a slit and an orifice
(2012)The flow of a monatomic gas through a slit and an orifice due to an arbitrarily large pressure difference is examined on the basis of the nonlinear Bhatnagar-Gross-Krook (BGK) model equation, subject to Maxwell diffuse ... -
Pyrolytic laser-based chemical vapour deposition of TiC coatings
(1995)TiC layers have been successfully deposited locally on D2 tool steel specimens and miniature industrial tools with the aim to improve their mechanical and chemical surface properties. The deposition process was based on a ... -
QAM and PSK OFDM RoFSO Over M-Turbulence Induced Fading Channels
(2015)Free-Space Optical (FSO) technology can effectively transfer multiple radio-frequency signals, and this new technique is commonly referred in the technical literature as radio on FSO (RoFSO). In the present study, we ... -
Rarefied gas flow through short tubes into vacuum
(2008)A rarefied gas flow into vacuum through a tube of finite length is investigated over the whole range of gas rarefaction by the direct simulation Monte Carlo method. The nonequilibrium effects at the inlet and outlet of the ... -
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 ... -
Simulation of gas flow through tubes of finite length over the whole range of rarefaction for various pressure drop ratios
(2009)The rarefied gas flow through circular tubes of finite length has been investigated computationally by the direct simulation Monte Carlo method. The reduced flow rate and the flow field have been calculated as functions ... -
Superhydrophobic films for the protection of outdoor cultural heritage assets
(2009)A very simple method that can be used to impart superhydrophobicity to stone surfaces of monuments using common and low-cost materials that are already employed or are easy to be found by conservators is presented. A ... -
Surface hardening of low-alloy 15CrNi6 steel by CO2 laser beam
(1999)The study investigates laser transformation hardening in the low-alloy 15CrNi6 case-hardening steel. The effect of process parameters such as beam power, beam diameter and travel speed on microstructure, case depth and ... -
Surface Properties of Superhydrophobic Coatings for Stone Protection
(2009)Superhydrophobic films are produced by a simple and low cost method. Silica (SiO(2)) nanoparticles are dispersed in solutions of Rhodorsil 224, a commercial poly(alkyl siloxane) which is used for the protection of outdoor ... -
Time-dependent rarefied gas flow of single gases and binary gas mixtures into vacuum
(2014)Time-dependent flows of single gases and binary gas mixtures with various molar fractions from a chamber through a short tube into vacuum are examined by simulations and experiments. The main goal is the comparison of the ...
