Low Z impurity transport in tokamaks. [Neoclassical transport theory] [PDF]

, 1978
Low Z impurity transport in tokamaks was simulated with a one-dimensional impurity transport model including both neoclassical and anomalous transport. The neoclassical fluxes are due to collisions between the background plasma and impurity ions as well as collisions between the various ionization states. The evaluation of the neoclassical fluxes takes

Disparate clump approximation in neoclassical plasma transport theory [PDF]

, 1978
A model of a multiple ion plasma is considered in which the system may contain many atomic species, each with an arbitrary number of charge states, but in which the atomic species are disparate in mass. Using this approximation is calculated in analytic form, the multispecies Spitzer function, from which there follow tractable expressions for the Ware ...

Assessing the impact of road transport infrastructure investment on economic development in South Africa

Journal of Transport and Supply Chain Management, 2017
Background: There has been considerable decline in the investment on road transport infrastructure in recent times, as a result of the dwindling economic investment owing to lowering gross domestic product (GDP) since 2009.

The impact of transport, land and fiscal policy on housing and economic geography in a small, open growth model

Journal of Transport and Land Use, 2013
This study proposes a spatial model to examine dynamic interactions among growth, economic geography, the housing market, and public goods in a small, open economic growth model. We emphasize the impact of transport, land and fiscal policy on the spatial

THE LARGE ASPECT RATIO LIMIT OF NEOCLASSICAL TRANSPORT THEORY [PDF]

, 2002
OAK B202 THE LARGE ASPECT RATIO LIMIT OF NEOCLASSICAL TRANSPORT THEORY. This article presents a comprehensive description of neoclassical transport theory in the banana regime for large aspect ratio flux surfaces of arbitrary shapes. The method of matched asymptotic expansions is used to obtain analytical solutions for plasma distribution functions and

SOLPS-ITER modification for impurity transport modelling in the tokamak pedestal region

Nuclear Materials and Energy
Kinetic corrections to SOLPS-ITER fluid equations are made to extend their applicability for description of the neoclassical part of impurity transport to collisionless regimes of the main ions.

Tree-based approaches for understanding growth patterns in the European regions

REGION, 2016
The paper describes an empirical analysis to understand the main drivers of economic growth in the European Union (EU) regions in the past decade. The analysis maintains the traditional factors of growth used in the literature on regional growth - stage ...

INTERNATIONAL BIOMASS TRADE AND SUSTAINABLE DEVELOPMENT: AN OVERVIEW [PDF]

CES Working Papers, 2011
It is crystal clear that the neoclassical economical theory, despite being probably the best growth model ever invented by man, tickled a cost of environmental degradation which can threaten our wealth and even our existence. For this reason, the concept
