1. Os “altos círculos” no mercado de transportes em São Paulo
Resumo Em gestação há quatro anos, a cidade de São Paulo aguarda as novas licitações dos serviços de ônibus. Nesse período, movimentações têm problematizado os graus de concentração desse mercado, tanto fora quando dentro da Prefeitura. Até o momento, todavia, sabe-se muito pouco sobre a composição e as transformações do conjunto das empr

2. Writing the literature review for empirical papers
Abstract Paper aims The purpose of the paper is to offer guidance regarding how to write a Literature Review for empirical papers, that provides adequate background and convincing support. The literature review plays the fundamental role of unveiling the theory, or theories, that underpin the paper argument, sets its limits, and defines and clarifies the ma

3. Predicting Runoff Risks by Digital Soil Mapping
ABSTRACT Digital soil mapping (DSM) permits continuous mapping soil types and properties through raster formats considering variation within soil class, in contrast to the traditional mapping that only considers spatial variation of soils at the boundaries of delineated polygons. The objective of this study was to compare the performance of SoLIM (Soil Land

4. PHASE EQUILIBRIA FOR BINARY SYSTEMS CONTAINING IONIC LIQUID WITH WATER OR HYDROCARBONS
Abstract In this work, the mutual solubilities of sets of ionic liquids ([CnMIM] [TF2N] (n = 4, 8, 12), [C4PY] [TF2N], [C8MIM] [OTF]) and organic compounds (heptane, o-xylene, toluene, or water) are investigated. The experimental data measured for these systems were used to adjust the binary interaction parameters between their components for the Non-Random

5. FSM-Based Test Case Generation Methods Applied to Test the Communication Software on Board the ITASAT University Satellite: A Case Study
ABSTRACT: The software in satellite applications has become increasingly larger, more complex and more integrated, so its verification and validation require exploration of new approaches. In this paper we present a Model-Based Testing (MBT) approach applied to the Communication Module of the ITASAT-1 university satellite. The models are Finite State Machine

6. Integral transform solution of natural convection in a square cavity with volumetric heat generation
The generalized integral transform technique (GITT) is employed to obtain a hybrid numerical-analytical solution of natural convection in a cavity with volumetric heat generation. The hybrid nature of this approach allows for the establishment of benchmark results in the solution of non-linear partial differential equation systems, including the coupled set

7. Análise de observabilidade e de redundância de medidas no contexto de estimação de estado trifásica / Observability and measurement redundancy analysis on three-phase state estimation
Este trabalho de dissertação trata do problema de observabilidade e redundância de medidas para efeito de estimação de estado trifásica. É proposta a extensão de uma metodologia numérica eficiente para análise de observabilidade e identificação de medidas críticas e conjuntos críticos de medidas, desenvolvida para modelagem por fase, a fim de c

8. Análise do processo de formação de estratégias de marketing no jornal Correio da Paraíba
The main objective that motivated this research was to analyze the formation process of marketing strategies in the newspaper Correio da Paraiba in the period from 1991 to 2010. The research sets a qualitative kind, descriptive and is a single case study. The research scenario was the newspaper Correio da Paraiba, which covered six interviewed, three from to

9. Contrast sensitivity and retinal ganglion cell responses in the primate
Human contrast sensitivity is considered in relation to the responses delivered by retinal ganglion cells of the primate to luminance and chromatic contrast. At different temporal frequencies, response amplitude relative to response variability determines the limit to sensitivity of a single ganglion cell. This can be related to specific models of central de

10. Laparoscopic skill laboratory in urological surgery: tools and methods for resident training
PURPOSE: Laparoscopy has certainly brought considerable benefits to patients, but laparoscopic surgery requires a set of skills different from open surgery, and learning in the operating room may increase surgical time, and even may be harmful to patients. Several training programs have been developed to decrease these potential prejudices. PURPOSES: to desc

11. A topological approach to the identification of critical measurements in power-system state estimation
This paper presents a new topological methodology for critical measurements identification in observable networks. A measurement is said to be critical, in an observability sense, if its removal from the measurement set makes the associated system lose observability. The proposed methodology is based on the properties of both, observable measurement subnetwo

12. Concentração de triptofano e variáveis cinemáticas a diferentes percentuais da velocidade crítica no nado crawl
The aim of this study was to investigate the changes in plasma tryptophan concentration ([TRP]) and kinematic variables in a series of interval training in different percentages of the critical speed (CS) in front crawl. Volunteers were 14 competitive male swimmers with at least four years experience in this style and swimming 48 ± 11 km per week. The subje
