1. Mine fleet cost evaluation - Dijkstra's optimized path
Abstract The transport distance in a mining operation strongly influences a mine operation revenue and its operational cycle because it is a fundamental part of the total mining costs. Generally, the transport route is determined based on an engineer's practical knowledge, which does not consider any mechanism to optimize the possible routes to be taken. In

2. The alternative model of silicone for experimental simulation of suture of living tissue in the teaching of surgical technique
Abstract Purpose: To develop a silicone alternative model of tissue suture simulation to be used in the teaching of surgical technique. Methods: Twelve alternative models of silicone for tissue suture simulation were manufactured and implemented as a tool for suture pattern training of undergraduate medical students of Universidade Federal do Amazonas. For

3. A COMBINATION OF DISCRETE EVENT SIMULATION AND MULTI-CRITERIA ANALYSIS TO CONFIGURE SUGARCANE DROP AND HOOK DELIVERY SYSTEMS
ABSTRACT This article explores decision analysis regarding Drop and Hook (D&H) transportation operations at sugarcane mills. By means of a case study, a combination of a discrete event simulation model and multi-attribute utility theory was used to evaluate different configurations for sugarcane delivery systems using internal, external, or no D&H systems. A

4. A GENERIC TACTICAL PLANNING MODEL TO SUPPLY A BIOREFINERY WITH BIOMASS
ABSTRACT The supply chains which bring biomass to biorefineries play a critical role in biofuel production. Optimization models can help decision makers to design more efficient chains and minimize the cost of biomass delivered to the refineries. This article based on a French national research project on biomass logistics considers one refinery, able to pro

5. COST-EFFECTIVE BANDWIDTH PROVISIONING IN MICROWAVE WIRELESS NETWORKS UNDER UNRELIABLE CHANNEL CONDITIONS
ABSTRACT Cost-effective planning and dimensioning of backhaul microwave networks under unreliable channel conditions remains a relatively underexplored area in the literature. In particular, bandwidth assignment requires special attention as the transport capacity of microwave links is prone to variations due to, e.g., weather conditions. In this paper, we f

6. A cost prediction model for machine operation in multi-field production systems
ABSTRACT Capacity planning in agricultural field operations needs to give consideration to the operational system design which involves the selection and dimensioning of production components, such as machinery and equipment. Capacity planning models currently onstream are generally based on average norm data and not on specific farm data which may vary from

7. Busca heurística e inferência de parâmetros cinéticos de reações de hidrotratamento de óleo diesel a partir de dados experimentais escassos
Currently, the amount of contaminants (such as sulfur, nitrogen and aromatics) in diesel oil is strictly controlled, due to their impact on pollutant emissions. The most important process used to meet fuel specifications regarding contaminants is the catalytic hydrogenation, specifically hydrotreatment (HDT). Optimization of the HDT process can benefit from

8. 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

9. Algoritmos evolucionÃrios multipopulaÃÃo na otimizaÃÃo multiobjetiva da remediaÃÃo de Ãguas subterrÃneas / Multi-population Evolutionary Algorithm Multi-Objective Optimization of Groundwater Remediation
Through the last three decades the evolutionary algorithms have been successful on application to many areas. Easily applied, efficiency and confidence are the main advantages of the evolutionary algorithms. In the groundwater remediation, generally, the objectives are the cost minimization, minimization of contaminant presence, maximization of pumping effic

10. Study of mixers fertilizers plants localization in brazilian Center-West region using a linear programming model / Estudo de localização de fábricas misturadoras de adubo na região Centro-Oeste brasileira utilizando um modelo de programação linear
Currently, the brazilian agribusiness is responsible for about 37% of the national PIB and face up to two of the great challenges in its constant growth which are the high dependence of chemical products (fertilizers) to expand its agricultural frontier and consequently, the distance (and transports costs) that this frontiers impose to be overcome, as much f

11. An approach to design feedback controllers for flight control systems employing the concepts of gain scheduling and optimization.
The role of feedback in the design of aircraft stability and control is becoming increasingly important. The basic reason driving this trend is the necessity to cope with a growing number of more stringent requirements, which are sometimes conflicting. This work presents a design methodology applicable to flight control laws, which can be either a control an

12. Essays in Applied Econometrics
This thesis is divided in three essays. The first essay examines the reactions by incumbent airlines to the threat and actual entry of the low-cost carrier Gol in the Brazilian domestic air transport market. By estimating the reactions in prices, quantities and supply variables, it investigates the plausibility of theories of entry deterrence and accommodati
