Network optimization techniques

This chapter is devoted to modeling and optimization techniques applicable to communication network design and planning. The main emphasis is put on the models dealing with optimization of the capacity of network resources and traffic routing that lead to tractable optimization problems. It is a common belief that the right means for such modeling are multicommodity flow networks (MFN). MFN form a

The Post-Communist Afterlife of Dissidents: The Case of Herta Müller

This chapter explores the role of the dissident intellectual in the post-dictatorship era. More specifically, it looks at the reaction in the Romanian cultural press and in the daily newspapers to the awarding of the 2009 Nobel Prize in Literature to Herta Müller, a Romanian-born German writer. Müller is known for her anti-Communist stance as well as her critique of those Romanian political and in

Effects of Protons and Small Alcohols on the Oxygen-Evolving Complex of Photosystem II

Higher plants and algae use oxygenic photosynthesis to convert solar energy to reducing equivalents and chemical energy. The ultimate electron donor to oxygenic photosynthesis is water. Oxidation of water to oxygen occurs in the oxygen-evolving complex (OEC) in Photosystem II (PSII). The OEC is composed of four Mn atoms, Ca2+ and Cl-. The OEC cycles through five states (S0 - S4) during oxidation o

Heroes and Victims : The Holocaust in Israeli Historical Consciousness

The interest in the Holocaust has been growing continuously over the last decades, and this study deals with how the Holocaust has been perceived, interpreted and used in an Israeli context. The central theoretical concept in this study is historical consciousness, and the aim is to analyze the place of the Holocaust in Israeli historical consciousness. This concept should be understood as the wa

Q2 Evolution of the Neutron Spin Structure Moments using a He-3 Target

We have measured the spin structure functions g1 and g2 of 3He in a double-spin experiment by inclusively scattering polarized electrons at energies ranging from 0.862 to 5.058 GeV off a polarized 3He target at a 15.5° scattering angle. Excitation energies covered the resonance and the onset of the deep inelastic regions. We have determined for the first time the Q2 evolution of 1(Q2)=g1(x,Q2)dx,

An approach of the geometrical-based single bounce elliptical channel model for mobile environments

The simulation approach is an important tool used for the design and implementation of mobile radio systems with an emphasis on the propagation modeling for wireless channel. We carried out simulations for three different street positions scenarios of the receiver, (mobile station), using the geometrical-based single bounce elliptical channel model, as might be appropriate for microcellular applic
