13. Cash management policies by evolutionary models: a comparison using the Miller-Orr model
This work aims to apply genetic algorithms (GA) and particle swarm optimization (PSO) to managing cash balance, comparing performance results between computational models and the Miller-Orr model. Thus, the paper proposes the application of computational evolutionary models to minimize the total cost of cash balance maintenance, obtaining the parameters for

14. A Study of Physical and Numerical Effects of Dissipation on Turbulent Flow Simulations
ABSTRACT: The present work is primarily concerned with studying the effects of artificial dissipation and of certain diffusive terms in the turbulence model formulation on the capability of representing turbulent boundary layer flows. The flows of interest in the present case are assumed to be adequately represented by the compressible Reynolds-averaged Navi

15. O processo de gestão e controle dos fluxos de caixa em um banco brasileiro: uma análise à luz da abordagem do ciclo de vida organizacional / The process of management and control of cash flows in a Brazilian bank: an analysis according the organizational life cycle approach
This work aims to expand the knowledge about the activity of cash flow management and control in the banking sector, which is not much explored in research and literature, thus contributing to a better understanding of this activity, since for any company to optimize cash flows management is important, and this task is even more critical to a bank, because t

16. A reinserção dos cursos de água em áreas urbanas. Estudo de caso: Microbacia do Córrego Jataí - Uberlândia /MG / The reinsertion of the watercourses in urban areas. Case study: the Stream watershed Jataí - Uberlândia/MG
The main objective of this work is to promote the reinsertion of urban water in the context of physical and territorial planning, in the cities, through the study of the watershed of Jataí stream in Uberlândia-MG. Pursuiting the rebalancing of the waters with the urban environment, this work promote the connectivity and physical strengthening of the relati

17. Efeitos da formação e operação de um reservatório de pequena regularização na alteração da qualidade da água e do regime hidrológico na planície de inundação do Pantanal
The formation of reservoirs changes the quality and quantity of water, both upstream and downstream, and the direction and magnitude of such changes depend on their characteristics of construction, operation, morphometry, as well as hydrological regime and climate of the region. However, much of this knowledge was based on large reservoirs, which is not the

19. Investigação experimental e analítica do escoamento ao redor de cilindro circular com supressores de VIV. / Experimental and analytical investigation of the flow around circular cylinder with VIV suppressors.
The fluid flow around bluff bodies is one of the main problems in fluid mechanics. The investigations of this phenomenon are based on analytical, numerical and experimental techniques. Each technique presents advantages and disadvantages, being impossible the comprehensive characterization of the flow though only one technique for the majority of body geomet

20. NUMERICAL ANALYSIS OF THE FLOW OF EMULSION THROUGH STRAIGHT AND CONSTRICTED CAPILLARIES / ANÁLISE NUMÉRICA DO ESCOAMENTO DE EMULSÕES ATRAVÉS DE CAPILARES RETOS E CAPILARES COM GARGANTA
Emulsion can be used as a mobility control agent in enhanced oil recovery methods in order to achieve a more efficient sweep of the reservoir. The application of such technique requires full understanding of how emulsions flow in a porous material. The macroscopic flow behavior can be determined based on the pore scale flow, at which emulsions cannot be trea

23. Os fluxos de IDE no Brasil nos anos 1990: uma revisão de literatura à luz das transformações em curso
The flows of foreign investments in Brazil starting from the 1990s have called attention due to the magnitude of the invested value, the prevalence of properties acquisitions as a preferential way of carrying out these investments, and for the primacy of the operations involving rivals companies. This article searches for an explanation for the cycle of fore

24. Relaxation approaches to the optimal control of the Euler equations
The treatment of control problems governed by systems of conservation laws poses serious challenges for analysis and numerical simulations. This is due mainly to shock waves that occur in the solution of nonlinear systems of conservation laws. In this article, the problem of the control of Euler flows in gas dynamics is considered. Numerically, two semi-line
