Neural Networks Architecture Evaluation in a Quantum Computer
In this work, we propose a quantum algorithm to evaluate neural networks
architectures named Quantum Neural Network Architecture Evaluation (QNNAE). The
proposed algorithm is based on a quantum associative memory and the learning
algorithm for artificial neural networks. Unlike conventional algorithms for
evaluating neural network architectures, QNNAE does not depend on
initialization of weights. The proposed algorithm has a binary output and
results in 0 with probability proportional to the performance of the network.
And its computational cost is equal to the computational cost to train a neural
network
Health benefits and uncertainty: an experimental analysis of the effects of risk presentation on auction bids for a healthful product
Experimental subjects receive a different presentation of a food product's potential health risk reductions if eaten regularly. They are then asked to bid for the product. Results suggest that the bids vary across the groups that receive differing risk information.

Approximate solutions for two dimensional problems in water pollution - component suppression schemes
In this work, a new hybrid method for solving problems in water pollution is proposed. The method furnishes approximate solutions for the two-dimensional transport equation in analytical form, in cases when the coupling between the hydrological and transport models can be neglected. The high speed processing of the scheme allows to simulate the transient dispersion in real time using low performance microcomputers.No trabalho a seguir Ă© proposto um novo mĂ©todo hĂbrido para a resolução de problemas em poluição aquática. O mĂ©todo fornece soluções aproximadas em forma analĂtica para a equação de transporte bidimensional, para situações nas quais o acoplamento entre os modelos hidrolĂłgico e de transporte pode ser ignorado. A alta velocidade de processamento do esquema hĂbrido permite simular a dispersĂŁo de poluentes em tempo real, empregado microcomputadores de baixa performance

The Effect of Risk Presentation on Product Valuation: An Experimental Analysis
We examine how people might evaluate a product with novel attribute, given various kinds of risk information. Using a product with healthful benefits, we assess subjects' willingness to pay given various kinds of health risk information conveying reduced health risks, life tradeoffs, and ambiguity. Four treatments in separate non-hypothetical experimental auctions are used to elicit willingness to pay values. Results suggest that willingness to pay vary across the groups that receive differing risk information. Specifically, willingness to pay was higher for the group that was given clear risk information and questions related to life tradeoffs than for the group given ambiguous risk information. Willingness to pay was lowest for the group that was given no risk information at all.Risk and Uncertainty,
Analysis, Design and Implementation of Biodiesel Projects in Brazil
During the oil crisis of the seventies, Brazil has developed a successful program for gasoline substitution by ethanol (Proálcool). Nowadays the biomass accounts for 27% of total national energy consumed in Brazil and the ethanol participates with 40% of the total national fuel consumption of Otto cycle vehicles. In 2004, the National Program for the Production and Use of Biodiesel (Biodiesel Program) was launched. One priority of the Biodiesel Program is the inclusion of family agriculture and smallholders into the production chain. The Federal University of Viçosa (UFV) has developed a software for the analysis of biodiesel projects with the participation of family agriculture. Results of production chain analysis and economic indicators calculated by the Biosoft system have allowed identifying the regular supply of oil at competitive prices as the key point to the efficiency of biodiesel production chains. The use of oil cake as feedstock is the leverage point of chain performance. The meal sale can lead to a vegetal oil price reduction, without compromising farmers´ income, since they can be able to set up their own oil extraction plants. Coordination is then the critical element and has the potential to improve the performance of both the biodiesel industry and the animal production chain.Agribusiness, Agricultural and Food Policy, Farm Management, Food Consumption/Nutrition/Food Safety, Industrial Organization,
