Crystallization in suspensions of hard spheres and turbidity

He, Yueming; Ackerson, Bruce J. - In: Physica A: Statistical Mechanics and its Applications 235 (1997) 1, pp. 194-203

The dynamics of crystallization have been investigated for suspensions of hard spheres by small angle light scattering …, direct imaging, and Bragg scattering. This work reports preliminary but complementary measurements of turbidity during … crystallization. The change in turbidity correlates with small angle light scattering for the smaller volume fractions studied, where …

Forces centrifuges et forces centripètes autour de la métropole tunisoise. Les entrepreneurs locaux, acteurs de la localisation industrielle

Metral, André - In: Revue d'économie régionale et urbaine avril (2003) 2, pp. 267-290

As we focus on the evolution of the relative weight of the Tunis area and the tunisian coastline in the industrial potential of this country, we would like now to complete the strictly economic analysis of the agglomeration and industrial location by an approach of the economy decision-makers as...

Biørn, Erik - 2014

The measurement error problem in linear time series regression, with focus on the impact of error memory, modeled as nite-order MA processes, is considered. Three prototype models, two bivariate and one univariate ARMA, and ways of handling the problem by using instrumental variables (IVs) are...

The Productive City Needs both - localization and urbanization economies across spatial scales in the city

Andersson, Martin; Larsson, Johan P; Lundblad, Joakim - 2015

This paper revisits a classical inquiry by addressing the question of localization and urbanization economies. We propose that specialization and diversity may offer externalities operating at different spatial scales. Using high-resolution geo-coded plant-level panel data for Swedish cities...
