1. QUALITY ANALYSIS FOR THE VRP SOLUTIONS USING COMPUTER VISION TECHNIQUES
ABSTRACT The Vehicle Routing Problem (VRP) is a classical problem, and when the number of customers is very large, the task of finding the optimal solution can be extremely complex. It is still necessary to find an effective way to evaluate the quality of solutions when there is no known optimal solution. This work presents a suggestion to analyze the qualit

2. Privacidade de localização geográfica em consultas a serviços públicos Web de localização: uma abordagem baseada em médias aleatórias
The increasing demand for Location-Based Services (LBSs) has increased the need for solutions that consider the privacy of queries in public LBSs. The currently proposed approaches rely mainly on the construction of an anonymizing spatial region (ASR) based on a rectangle containing a user consultant and at least other K−1 users, thereby setting a K le

5. Estudo da resposta de cristais de quartzo natural para dosimetria termoluminescente
In the last few years, a number of studies have been carried out with the objective of characterizing and/or developing materials with thermoluminescence properties (TL) for the purpose of ionizing radiation dosimetry. The aim of this study consists in the characterization of the thermoluminescence properties of natural quartz crystals, to be used for radiat

6. Potencials and electric fields inside and outside resistive conductors carrying steady currents / Potenciais e campos eletricos dentro e fora de condutores resistivos com correntes constantes
In Chapter 1 we present an introduction about the electric field inside and outside resistive conductors carrying steady currents. We also discuss the distribution of surface charges that maintains the current fiow and its relation with these electric fields. We present some experiments related with these electric fields outside conductors with steady curren

7. Resfriamento por convecção natural de placas de circuito impresso formando um canal vertical
Experiments and theoretical modeling were carried out on the cooling by natural convection of an array of vertical parallel printed circuit boards. The thermal analysis of printed circuit boards (PCB) for predicting, as accurately as possible, the temperature of each component is important to obtain an optimal thermal design and to check the performance of a

8. Avaliação numerica de esquemas para equação eliptica de transporte conectivo-difuso
This work presents a study about five finite difference schemes applied to the numerical solution of convective diffusive transport equation of heat, momentum or species mass. The case of parallel flow is employed where the analysed property is expressed in two-dimensional coordinates. The schemes are the second order ones central differencing, Allen and Sou

9. Neuron recognition by parallel Potts segmentation
Identifying neurons and their spatial coordinates in images of the cerebral cortex is a necessary step in the quantitative analysis of spatial organization in the brain. This is especially important in the study of Alzheimer's disease (AD), in which spatial neuronal organization and relationships are highly disrupted because of neuronal loss. To automate neu

10. Model for the Structure of the Shape-Maintaining Layer of the Escherichia coli Cell Envelope
The surface area per repeating murein unit (i.e. per molecule of diaminopimelate) has been determined for the cell envelopes of the Escherichia coli strains K-12 and W. This area was constantly found to be 1.3 nm2. Using this value and other previously determined properties of E. coli murein, a three-dimensional model of murein is proposed. The model specifi

11. The free energy landscape for β hairpin folding in explicit water
The folding free energy landscape of the C-terminal β hairpin of protein G has been explored in this study with explicit solvent under periodic boundary condition and oplsaa force field. A highly parallel replica exchange method that combines molecular dynamics trajectories with a temperature exchange Monte Carlo process is used for sampling with the h

12. Fast Folding of an RNA Tetraloop on a Rugged Energy Landscape Detected by a Stacking-Sensitive Probe
We investigate the microsecond-timescale kinetics of the RNA hairpin ga∗cUUCGguc. The fluorescent nucleotide 2-aminopurine (a∗) reports mainly on base stacking. Ten kinetic traces and the temperature denaturation curve are globally fitted to four-state models of the free-energy surface. In the best-fitting sequential model, the hairpin unfolds over succe
