Resource allocation schemes for orthogonal frequency division multiple access- (OFDMA-) based cognitive radio (CR) networks that impose minimum and maximum rate constraints are considered.To demonstrate the practical application of such systems, we consider the transmission of scalable video sequences.An integer programming (IP) formulation of the
The goal of this study is to identify gaming slang terms in the news articles of highly rated Russian media.Three online newspapers of various types were used as an empirical material: Kommersant (the Hockey Stick first private business newspaper in Russia), RBC (a socio-political analytical newspaper) and Rossiyskaya Gazeta (agency of the Russian
With its well-known biological toxicity, the excessive concentrations of sulfide in tannery wastewaters may upset the biological treatment processes, thus leading to a COMBO STRAW BENT substantial decrease in the efficiency of treatment plants.The presence of sulfide in wastewaters may dramatically interfere with microbial activities and consequent
Delving into the current chronicles of research findings, explorations of biodiesel production and utilization in diesel engines have been at the forefront of sustainable and creative energy discovery.Far beyond the problems of energy crises, renewable biodiesel offers unlimited solutions to the associated issues of depleting reserves and harmful e
Computationally fast electromagnetic models of eddy current sensors are required in model-based measurements, Brake Cam machine interpretation approaches or in the sensor design phase.If a sensor geometry allows it, the analytical approach to the modeling has significant advantages in comparison to numerical methods, most notably less demanding imp
