Quantum approach to GaAs MESFETs
(IEEE, 1997)
This paper is completely devoted to an original method of determination of carriers distribution in GaAs MESFET channel based on the investigation of transport equation including a quantum correction term.
Speedup of Clos packet switches that provide delay guarantees
(IEEE, New York, 2005)
A multihop Clos fabric may provide the terabit capacity by using the smaller switching elements (SE). When the traffic load is balanced over the switches in a middle stage, all the traffic would get through the fabric, as ...
Precipitation of the beta-phase and corrosion behavior of an al-6.8 wt.% mg alloy
(John Wiley & Sons, Chichester, 2012)
This study was performed on the Al-Mg alloy with the chemical composition: Al-Mg6.8-Mn0.51-Fe0.2-Si0.1. As-received cold rolled material (O-temper) was subjected to (i) cold rolling and annealing at 265 degrees C and 320 ...
Preparation of heterogeneous catalyst for biodlesel synthesis
(2007 AIChE Annual Meeting, 2007)
Certain disadvantages of conventional processes of biodiesel, i.e. fatty acid methyl esters (FAME) synthesis could be avoided by applying new technologies which are based on using heterogeneous catalyst. In this study a ...
Supercritical carbon dioxide extraction of essential oils and mathematical modelling on the micro-scale - General model
(CHISA 2006 - 17th International Congress of Chemical and Process Engineering, 2006)
General model for the supercritical carbon dioxide extraction of essential oils on the secretory structure scale (micro-scale) is presented in this study. The model containes Source and Transfer term which describes mass ...
Design, implementation and testing of the controller for the terabit packet switch
(IEEE, New York, 2006)
The sequential greedy scheduling (SGS) is a scalable algorithm that provides non-blocking in high-capacity packet switches. We implemented the SGS scheduler in the FPGA device, and examined its scalability and speed. Then, ...
Exploiting the Nonlinear Frequency Response Method to Evaluate the Potential of Forced Periodic Operation of Reactors
(American Institute of Chemical Engineers Annual Meeting (AIChE Annual Meeting), San Francisco, USA, 2016)
Forced periodic operations of chemical reactors possess significant potential to improve numerous performance criteria. The corresponding analysis of reaction systems and the estimation of the magnitude of possible performance ...
The influence of low-temperature plasma treatment on some wool properties
(American Institute of Physics, 2004)
If swift heavy ions (5 MeV/u) hit solid targets energy is transferred to the electrons of the solid. Caused by the high electronic energy deposition along the flight path of the ion a cylindrical shaped chemical or structural ...
Supercritical carbon dioxide extraction of carrot fruit oil - Comparison with hydrodistillation and modelling
(CHISA 2006 - 17th International Congress of Chemical and Process Engineering, 2006)
In this study the compositions of Carrot fruit (Daucus carrota, cultivar Chanteney) essential oil obtained by hydrodistillation and its extract obtained by supercritical carbon dioxide extraction at 313 K and 10 MPa were ...
Supercritical carbon dioxide extraction and fractionation of hyper for in and adhyperforin from St. John's Wort (Hypericum perforatum L.)
(CHISA 2006 - 17th International Congress of Chemical and Process Engineering, 2006)
Plants of the genus Hypericum have been used as traditional medicinal plants in various parts of the world. St. John's Wort (Hypericum perforatum L.) has been reported as an antidepressive, antiviral, antimicrobial, ...
