1. Aceite residual automotriz como aditivo en mezclas de hormigón: Si es factible su uso
ABSTRACT Finding a use for Automotive Residual Oil (ARO) is preponderant for society, since one liter of this liquid is capable of contaminating one million liters of drinking water, without counting the damages to agricultural soils and groundwater. The purpose of this work is to study the physical and mechanical properties of concrete by incorporating ARA

2. Controlling sintering and grain growth of nanoceramics
Resumo Sinterização e crescimento de grão são processos fundamentais que afetam a evolução microestrutural das cerâmicas. Os modelos fenomenológicos que descrevem esses processos, conforme encontrados nos livros didáticos, são simplificações do conjunto altamente dinâmico de parâmetros do sistema, o que leva à previsibilidade limitada e à nec

3. SHORTEST PATHS ON DYNAMIC GRAPHS: A SURVEY
ABSTRACT This paper provides an overview of the state-of-the art and the current research trends concerning shortest paths problem on dynamic graphs. The discussion is divided in two main topics: reoptimization and time-dependent shortest paths. Reoptimization consists in the solution of a sequence of shortest path problems in which each instance slightly di

4. Path Planning for Unmanned Underwater Vehicle in 3D Space with Obstacles Using Spline-Imperialist Competitive Algorithm and Optimal Interval Type-2 Fuzzy Logic Controller
Abstract In this research, generation of a short and smooth path in three-dimensional space with obstacles for guiding an Unmanned Underwater Vehicle (UUV) without collision is investigated. This is done by utilizing spline technique, in which the spline control points positions are determined by Imperialist Competitive Algorithm (ICA) in three-dimensional s

5. Particle swarm optimization in WDM/OCDM networks with physical impairments
In this paper, optimization procedures based on particle swarm optimization (PSO) are investigated, aiming to efficiently solve the optimal resource allocation for signal-to-noise plus interference ratio (SNIR) optimization of optical code paths (OCPs) from wavelength division multiplexing/optical code division multiplexing (WDM/OCDM) considering imperfectio

6. Ensaios sobre a meta de inflação ótima para o Brasil / Optimal inflation target for the Brazilian economy
Inflation targeting regimes have been adopted by a large number of countries in recent years. Obviously, the definition of the actual inflation target to be pursued is an essential part of this regime. This work aims to make a contribution to the debate about the optimal target for Brazil. The three essays follow different paths in an attempt to estimate the

7. Impacto de condicionantes hidrológicas na definição de traçados rodoviários : aplicação na rodovia TO-247
The contribution of this research is given by the design of effective impacts of highways, through the expansion of the influence areas beyond the linear tracks, adding the assessment of the environmental sensitivity of watersheds in order to optimize the layout of road projects. It was produced an orderly and systematic approach of the cause and consequence

8. Análise matemática de um modelo de controle de populações de mosquitos / A mathematical analysis of a model for control of mosquito populations
The proliferation of mosquitoes in inhabited regions is an important public health issue since these insects are vectors of several infectious diseases. Thus, the study of techniques for controlling of mosquito populations has an important role in the quest for efficient combat techniques; in particular, the adequate understanding of mathematical models that

9. Optimal paths for minimizing lost available work during heat transfer processes with a generalized heat transfer law
A common of finite-time heat transfer processes between high- and low-temperature sides with a generalized heat transfer law [q ∝ (Δ(Tn ))m] are studied in this paper. The optimal heating and cooling configurations for minimizing lost available work are derived for the fixed initial and final temperatures of the working fluid of the system (low-temperatur

10. Dynamic modeling of overload in scale free networks
We introduce a simple dynamic model to investigate the fragmentation of transport networks. The transport properties like as the size of largest connected cluster, the length of the minimum paths and the optimal paths between a pair of nodes of the network were evaluated upon continuously increasing the load on the system. We use two load insertion strategie

11. Using advanced CAM-systems for optimized HSC-machining of complex free form surfaces
High speed cutting (HSC) offers the opportunity to significantly reduce machining times as well as to minimize manual rework for complex free form surfaces in the die and mould making industry. To achieve the best results it is also necessary to apply HSC-suitable machining strategies to perform optimal high speed milling operations. This paper presents a me

12. Zona de empate : o elo entre transformadas de watershed e conexidade nebulosa / Tie-zone : the bridge between watershed transforms and fuzzy connectedness
This thesis introduces the new concept of tie-zone transform that unifies the multiple solutions of a watershed transform, by conserving only the common parts among them such that the differing parts constitute the tie zone. The tie zone applied to the watershed via image-foresting transform (TZ-IFTWT) proves to be a link between watershed transforms based o
