1. Emissões de poluentes atmosféricos em condições reais de pavimentação asfáltica: material particulado, black carbon e hidrocarbonetos policíclicos aromáticos
Intensive use of asphalt generates pollutants into the atmosphere which are harmful to the environment and worrying for occupational health. The application of asphalt products leads to emissions of significant concentrations of polycyclic aromatic hydrocarbons (PAHs) and particulate matter (PM) to the atmosphere. This paper aims to assess the pollutant emis

2. Single-Bus and Dual-Bus Architectures of Electrical Power Systems for Small Spacecraft
ABSTRACT Nowadays, it has become possible for universities and new businesses to launch satellites of reduced size and cost fulfilling viable missions. Nevertheless, there is still a considerable failure rate that reduces the expected lifetime of these spacecraft. One of the main causes of failure is the power system. Redundancy is one of the main options to

4. The orientation and mobility of visual impaired people in bus and subway networks in Brazil
Resumo Orientação espacial depende tanto da informação contida no ambiente quanto da capacidade do indivíduo em perceber e lidar com essa informação. Para poder entender um sistema de transporte público urbano e mover-se de forma independente de um lugar para outro, esse serviço deve fornecer informações acessíveis aos usuários, para que esses p

5. Electromechanical Impedance - Based Structural Health Monitoring Instrumentation System Applied to Aircraft Structures and Employing a Multiplexed Sensor Array
ABSTRACT: The electromechanical impedance method has been seen as a promising tool for structural health monitoring regarding different types of structures and purposes. Most importantly, this method can be used in real-time applications. Frequently, massive, high-cost, single-channel impedance analyzers are used to process the time domain data, aiming at ob

6. Analysis of expansions of a bus transit network considering the needs identified by the community: case study
Abstract Expansion analyses are performed on a bus transit network in the City of Laramie area in Wyoming. Expansion analysis is based on the needs identified by the bus transportation agency and the community. This paper examines the expansions, operations and sustainability of a bus transit in a small city having a population of 30,000 people. When funding

7. Cost-effective joints configurations of concrete pavements for a sustainable infrastructure
Abstract Nowadays, there are Concrete Pavements (CPs) with Joints Configurations (JCs) that reduce initial costs about 20%. But are these JCs produced by Early-Entry Saw-Cutting (EESC), Unsealed Joints (UJs) and Shorter Joint Spacing (ShJS) able to maintain the traditional performance of CPs? The aim of this paper is to analyze the effects of the joints beha

8. Exposure to particulate matter 2.5 mM collected at high traffic routes in Rio de Janeiro city: evaluation mutagenic, genotoxic and determination of health risks induced by polycyclic aromatic hydrocarbons / Exposição ao material particulado 2,5 m coletado em vias de alto tráfego da cidade do Rio de Janeiro: avaliação mutagênica, genotóxica e determinação de risco à saúde induzido por hidrocarbonetos policíclicos aromáticos
The mutagenicity of airborne particles from combustion is attributed primarily to polycyclic aromatic hydrocarbons (PAHs). We investigated the mutagenic activity of particulate matter (PM2.5) samples collected from three sites in Rio de Janeiro. Samples were collected using a high-volume sampler at Avenida Brasil, the campus of the Rio de Janeiro State Unive

9. A generic and open framework for multiword expressions treatment : from acquisition to applications
The treatment of multiword expressions (MWEs), like take off, bus stop and big deal, is a challenge for NLP applications. This kind of linguistic construction is not only arbitrary but also much more frequent than one would initially guess. This thesis investigates the behaviour of MWEs across different languages, domains and construction types, proposing an

10. Estimação de estado em sistemas elétricos de potência: composição de erros de medidas / State estimation in power systems: measurement error composition
Bretas et al. (2009) has proved, using geometric background, that the measurement error can be decomposed into two components the detectable and the undetectable component respectively. Bretas has also demonstrated that the current methodologies used for processing of gross errors (GE), consider only the detectable component of the error. Thus, depending on

11. Design of self-checking fully differential circuits and boards
A design methodology for on-line testing analog linear fully differential (FD) circuits is presented in this work. The test strategy is based on concurrently monitoring via an analog checker the common mode (CM) at the inputs of all amplifiers. The totally self-checking (TSC) goal is achieved for linear FD implementations provided that the checker CM thresho

12. Operações de serviços de pós-venda baseadas em conhecimento: o caso Carrier Transicold Brasil
The performance of technical assistance depends on how information and knowledge are disseminated to a network of services. This work was developed with the aim of identifying how the operations of after-sales service can generate competitive categories for a technical assistance network based on quality management and knowledge. This case study included par
