COMPUTER SIMULATION OF THE FLOTATION PROCESS TAKING INTO ACCOUNT THE HYDRODYNAMIC STRUCTURE OF INTERACTION FLOWS

Abstract:

This article discusses computer simulation of the flotation process, taking into account the hydrodynamic structure of the interacting flows. Various variants are studied, and the possibility of using differential equations of typical models of inertial and integral links is shown. This made it possible to justify a multistage method of identifying a flotation facility. The results obtained allowed us to develop acceptable computer models of the dynamics of the flotation process. Methods for modeling an object and a control system for flotation complexes based on computer models of the process occurring in the gas and liquid phase have been developed.

LOCAL CLUSTERS IN A GLOBAL ECONOMY

Abstract:

Economic geography during an era of global competition involves a paradox. It is widely recognized that changes in technology and competition have diminished many of the traditional roles of location. Yet clusters, or geographic concentrations of interconnected companies, are a striking feature of
virtually every national, regional, state, and even metropolitan economy, especially in more advanced nations. The prevalence of clusters reveals important insights about the microeconomics of competition and the role of location in competitive advantage. Even as old reasons for clustering have diminished in importance with globalization, new influences of clusters on competition have taken on growing importance in an increasingly complex, knowledge-based, and dynamic economy. Clusters represent a new way of thinking about national, state, and local economies, and they necessitate new roles for companies, government, and other institutions in enhancing competitiveness. Resources, capital, technology, and other inputs can be efficiently sourced in global markets.
