13. Development of Three-Dimensional Electrodes of PbO2 Electrodeposited on Reticulated Vitreous Carbon for Organic Eletrooxidation
The application of electrochemical technology for the degradation of organic pollutants often faces two main problems, related to the anode material and mass transport limitations. Although PbO2 electrode is inexpensive and provides satisfactory electrooxidation kinetics, in the form of plane electrodes it is unable to resolve the mass transfer problem that

14. Efficiency Comparison of Bus Operators in Delhi
There is an apparent inefficiency in the workings of the primary bus operators in New Delhi. The paper focuses on labor inefficiency and compares the compensation schemes offered to the conductors of the two major bus operators in Delhi- Delhi Transport Corporation (DTC) and Delhi Integrated Multi-Modal Transit System (DIMTS). Such a study which compares the

16. Da rodovia da morte ao desvio pela vida: os conflitos socioambientais em torno da duplicação da BR-101 em Araranguá/SC (1995-2011) / From the highway to the deviation of the dead for life: conflicts around the duplication of the BR-101 in Araranguá / SC (1995 2011
The BR-101 in Araranguá is so related to the life of the city which is hardly mentioned in history books and research the city. Therefore, this research based in the History of the Present Time to delve into a subject comes to innovative local historiography. After years of development driven by agriculture and small industries organized themselves in refin

17. Numerical analysis of the nonlinear subgrid scale method
This paper presents the numerical analysis of the Nonlinear Subgrid Scale (NSGS) model for approximating singularly perturbed transport models. The NSGS is a free parameter subgrid stabilizing method that introduces an extra stability only onto the subgrid scales. Thisnew feature comes from the local control yielded by decomposing the velocity field into the

18. Solução da equação Sn multigrupo de transporte dependente do tempo em meio heterogêneo
In this dissertation is presented an analytical solution for the approximation SN transport equation with the time dependent power, to homogeneous plates as to heterogeneous, assuming a multigroup model with isotropic scattering. The main idea involves the following steps, in this order: construction of a solution to the equation mentioned in a homogeneous p

19. Modelos e algoritmos para um problema de bombeamento de múltiplos combustíveis em uma rede com um único duto unidirecional / Models and algorithms for a multiple product pipeline on a network with a single unidirectional pipe
One of the most economical and, with respect to the environment, safest ways to transport fuel is to pump them through pipeline networks. However, the several operational constraints that have to be considered turn the planning of these activities into a major challenge. Among the several cenarios in which the problem arises, in this dissertation we investig

20. A hybrid methodology to solve the container loading problem with weight distribution and cutting problems
Transport of goods has represented an important role in economic development throughout the history and ship containerization brought great advantages. Its invention in mid-1950s brought down the cost of transport and reduced time for loading and unloading cargo. Consequently, it increased efficiency of port working and reduced handling cargo to hours instea

21. Proposta de um modelo matemático para o problema dial-a-ride aplicado ao transporte de cadeirantes
Os problemas de transporte público de cadeirantes são comumente resolvidos pelo modelo Dial-a-Ride Problem (DARP) com janelas de tempo (Time Window - TW). Com base nas restrições de janela de tempo na origem e no destino de cada cliente, no número de veículos e na capacidade de cada um deles, deseja-se minimizar os custos de atendimento dessas demandas

23. Inclusão de MRI e informação multigrid a priori para inferência bayesiana de fontes de M/EEG / MRI image and multigrid a priori information for bayesian M/EEG source localization
Functional Neuroimaging has evolved in the last few decades with the introduction of techniques such as Positron Emission Tomography or PET and Functional Magnetic Ressonance Image or fMRI [Belliveau et al., 1991]. These allow observing brain activity with a resolution of a few millimeters and, due to the nature of the signal, a time resolution of the order

24. âModelagem da IntrusÃo Salina Utilizando Analise de Sensitividade Adjunta â Estudo de Caso: Cap-Bon/Tunisiaâ / "Modeling of Saline Intrusion Using Sensitivity Analysis Assistant - Case Study: Cap-Bon/Tunisia"
Today the water is a natural well which limits the socioeconomic development and even the subsistence of the population. An attempt to minimize the problem of water scarcity has used the farming of groundwater. However, this growth of the use of groundwater was done inappropriately and with inadequate wells construction. This practice was eventually put at r
