Faced with a scenario where the growth of urban centers is increasing, the BRT system comes as a viable solution to this, enabling the development of functional bus corridors, serving to meet the demand of rapid shifts, especially in areas with high population density. However, to characterize as a system, it is necessary to measure their level of performance in the face of various aspects that are part of his characterization. For this, the article aims to study the main criteria influencers for the development of a performance measurement system for the BRT systems in Brazil, using for this the bibliographic research, technical manuals and expert opinion about the subject, focusing, at the end of this, to reveal these criteria, aiming at the future the elaboration of indicators to facilitate its performance evaluation.

The goal of this paper is to show a study to evaluate the possibility of using ontologies to support maintenance procedures in IT equipment in a small power company. The aim is to improve the degree of reliability in detection of potential failures and defects in maintenance processes of information technology critical assets, trying to obtain less downtime of services that they provide. The methodological procedures used in this study were literature review, to present the modeling concepts of knowledge focused on ontologies creation and state of the art in building of field procedures describing the steps from initial drafting of ontology finishing with their tests. The results demonstrate that it is viable to utilize this technique, where the network equipment that keeps critical services require high level of availability on meeting the needs of the corporation.

Mainstream Traffic Flow Control (MTFC) with Variable Speed Limits (VSL) is a freeway traffic control method which aims to maximize throughput by regulating the mainstream flow upstream from a bottleneck. Recent studies in a macroscopic simulator have shown optimal and feedback MTFC potential to improve traffic conditions. In this paper, local feedback MTFC is applied in microscopic simulation for an on-ramp merge bottleneck. Traffic behavior reveals important aspects that had not been previously captured in macroscopic simulation. Mainly, the more realistic VSL application at specific points instead of along an entire freeway section produces a slower traffic response to speed limit changes. In addition, the nonlinear speed limit-flow relation observed in the microscopic model is more pronounced than what was observed at the macroscopic level. After appropriate modifications in the control law significant improvements in traffic conditions were obtained.

This study proposes to identify and select indicators contributing to the evaluation of the levels of sustainability in the family agriculture production of castor beans in the state of Paraíba. To achieve these objectives, we used the Pressure-State-Impact-Response (PSIR) model, which describes the human activities, processes and standards that impact on sustainable development. The methodology was based on Descriptive and Exploratory research applied in a case study of an agricultural cooperative. The primary data were collected through semi-structured interviews with representatives of public organs and agriculturists. Based on the reality and the problems that affecting the production system, a total 47 indicators were set, classified and tailored to the specifics of the activity, considering the different dimensions of sustainability. The results showed that the indicators selected enabled the systemic analysis of agricultural activity, facilitating the identification of the positive and negative aspects that influence the productive sector, and also propose possible solutions and improvements to stimulating the local oleaginous production.
