In this paper we introduce two models of opinion dynamics in oligopoly markets and apply them to a situation, where a new entrant challenges two incumbents of the same size. The models differ in the way the two forces influencing consumer choice - (local) social interactions and (global)...

The observation of substantial current drive from neutral beam injection (NBI) in TFTR, JET and DIII-D has led to renewed interest in a steady state, non-inductively driven tokamak. The discovery of apparently considerable neoclassical (bootstrap) current in TFTR, makes a steady state device...

A new strategy for validation of hydrocode predictions through the Bayesian analysis of radiographic data is presented. The Bayesian approach allows one to incorporate prior knowledge about the structure of the objects being analyzed and provides the foundation for assessing the reliability of...

In this paper, we introduce and discuss the passage to hydrodynamic equations for kinetic models of conservative economies, in which the density of wealth depends on additional parameters, like the propensity to invest. As in kinetic theory of rarefied gases, the closure depends on the knowledge...

Measurements and numerical simulations carried out off Mumbai coast for the period 22 October–22 November 2009 showed significant variations in water level and currents during cyclone Phyan. Changes in the meridional component of the current velocity were found to be highly significant during...

Although short-circuiting is broadly recognized as an important phenomenon in reactor designs, it is very difficult to compare the degree of short-circuiting among different reactor types from the hydraulic indexes in reality. Identification of reactor type was essential and necessary to solve...

Analyzing hydraulic risk involves simulating a high number of scenarios from which to draw statistical information about flood extent and depth in relation to variations in the defence conditions and the entity of the event. With the aim of keeping the computational times of simulations within...

A theory of nonlinear convective depletion is set up as a nanosphere translates fast through a semidilute polymer solution. For nanospheres a self-consistent field theory in the Rouse approximation is often legitimate. A self-similar solution of the convective depletion equation is argued to be...
