An Integrated Software Architecture for Bandwidth Adaptive Video Streaming
(World Acad Sci Eng & Tech-Waset, 2008)
Video streaming over lossy IP networks is very important issues due to the heterogeneous structure of networks. Infrastructure of the Internet exhibits variable bandwidths delays congestions and time-varying packet losses. ...
Design of practical matching networks with lumped elements via modeling
(IEEE, 2007)
It is a common practice to utilize commercially available software tools to design matching networks for wireless communication systems. Most of these tools require a properly selected matching network topology with good ...
Performance of space-time coded systems with transmit antenna selection
(IEEE, 2007)
We deal with transmit antenna selection for space-time coded (STC) systems over multiple input multiple output (MIMO) channels. Using pairwise error probability analysis and simulation results we show that transmit antenna ...
Reflectance-based Foster impedance data modeling
(Fachverlag Schiele Schon, 2007)
A reflectance-based method is presented to model a set of given Foster impedance data as a lossless singly terminated two-port consisting of lumped-elements in short or open termination. The basis of the new method rests ...
Apolipoprotein B gene variants are involved in the determination of blood glucose and lipid levels in patients with non-insulin dependent diabetes mellitus
(Wiley, 2006)
We have examined the frequency of the EcoRI XbaI and MspI RFLPs of the apolipoprotein B (apo 13) gene in I 10 type 2 diabetic patients and 9 1 healthy control subjects in order to ascertain whether variation in this gene ...
Influence of combined antioxidants against cadmium induced testicular damage
(Elsevier Science Bv, 2006)
Acute effects ofcadmium (Cd) and combined antioxidants were evaluated in Sprague-Dawley rat testes. The rats were subdivided into four groups. Cadmium chloride (2 mg/kg day) injected intraperitoneally during 8 days. Vitamin ...
A computational study on the amine-oxidation mechanism of monoamine oxidase: Insight into the polar nucleophilic mechanism
(Royal Soc Chemistry, 2006)
The proposed polar nucleophilic mechanism of MAO was investigated using quantum chemical calculations employing the semi-empirical PM3 method. In order to mimic the reaction at the enzyme's active site the reactions between ...
A fuzzy AHP approach to evaluating machine tool alternatives
(Springer, 2006)
Selecting process of a machine tool has been very important issue for companies for years because the improper selection of a machine tool might cause of many problems affecting negatively on productivity precision flexibility ...
Linear expansions for frequency selective channels in OFDM
(Elsevier GMBH Urban & Fischer Verlag, 2006)
Modeling the frequency selective fading channels as random processes we employ a linear expansion based on the Karhumen-Loeve (KL) series representation involving a complete set of orthogonal deterministic vectors with a ...
Ginkgo biloba extract regulates differentially the cell death induced by hydrogen peroxide and simvastatin
(Elsevier Science Bv, 2006)
Several human diseases have been associated with the overproduction of reactive oxygen species (ROS) and subsequently various antioxidants emerged as potential therapeutic agents that scavenge ROS. As an oxidative stress ...
