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, ...
Use of nonlinear frequency response analysis for model discrimination: Example - DMFC anode kinetics
(18th International Congress of Chemical and Process Engineering, CHISA 2008, 2008)
Nonlinear frequency response analysis is proven as a powerful tool for the characterization of nonlinear systems. A set of frequency response functions (FRF), which contain different information, is obtained. In a number ...
Design of the multicast controller for the high-capacity Internet router
(IEEE, New York, 2007)
High-capacity routers that circulate multicast packets have unique properties. Their architecture is non-blocking even for the multicast traffic. It also provides delay guarantees. This paper presents the detailed ...
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 ...
Enhanced Cell-ID+TA GSM positioning technique
(IEEE, New York, 2005)
The majority of existing GSM positioning techniques can be described as either costly or with limited performance. Basic GSM positioning techniques Cell-ID and Cell-ID+TA can be upgraded to decrease positioning error. We ...
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 ...
Preparation of heterogeneous catalyst for biodiesel synthesis
(2007 AIChE Annual Meeting, 2007)
Certain disadvantages of conventional processes of biodiesel, e.g., fatty acid methyl esters (FAME) synthesis could be avoided by applying new technologies that are based on using heterogeneous catalyst. A new type of ...
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 ...
Heat transfer conditions and ultrasonic measurements of alumina based refractories
(CHISA 2006 - 17th International Congress of Chemical and Process Engineering, 2006)
In this paper temperature difference and resistance parameters were used for prediction of thermal shock behavior of alumina based commercial refractories with content of Al2O3 from 28 % to 78 %. Thermal and mechanical ...
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, ...
