There are particular issues that hinder the performance of IT management committees, such as the lack of productivity, duration of the meetings, physical distance between members, and low quality of some complex decisions, among other restrictive factors. In this paper we present a method based on wisdom of crowds' theory and Analytic Hierarchy Process (AHP), designed to automate the process of group decision making for IT management committees. We conducted a case study in a Brazilian IT company, and the results indicate that managers considered our method and tool useful, preferable to the current decision-making method, complete and easy to use.

This work consists of a case study in Cariri, the second largest metropolitan area in the state of Ceará. For that, examples of irregularities are presented by means of the diagnosis of the study area, and then solutions based on the ABNT standards and federal legislation are proposed. To perform the analysis, a comparative method was applied, focusing on the aspects of construction that do not meet the requirements of the current legislation. Then, a spatial configuration more suitable to the areas of study was proposed, improving, therefore, the physical characteristics of the non- motorized transport, resulting in a reduction in traffic conflicts and in an improvement the quality of public spaces.

Performance and operation of railway structures can be influenced by ballast aggregates’ shape properties, which include the form itself, angularity and superficial texture. The aggregates shape properties and the particle size may be directly affected by many factors such as: the track usage time, the fouling material that can modify the original granulometry and the maintenance processes. In this context, it is necessary the evaluation of the aggregates’ shape properties aiming to verify how they can influence on railway’s performance and operation. This work measures these aggregates properties collected from quarries (origin) and aggregates collected after some operation time using ABNT, and AREMA standards, as well as the DIP technique. Results indicated that both materials meet ABNT specifications, the same did not happen when AREMA standards were used. Concerning the DIP results, changes were observed on form, sphericity, and superficial texture, caused by structural efforts from the traffic, by the time of operation that produces fine material and, mainly, by the maintenance procedures (tamping).

In Brasil, it is traditionally used CM-30 during the prime coat, but this material has kerosene as diluent of the Petroleum Asphalt Cement (CAP). In developed countries there is a major constraint on the use of the CM-30 primer. This restriction occurs because it is considered polluting to the environment due to proper handling of bituminous material, as well as the emission of Volatile Organic Hydrocarbons (VOC's). There are few published studies on bituminous primer, in Brazil and in the world highlighting the need to develop studies on the performance of alternative ligands that may in the future replace the CM-30. In Brazil, the selection of new binders in the laboratory to verify the penetration of bituminous priming, involves an exhaustive preparation of the Samples (CPs) which is very time consuming. For every variable to be tested (binder type and rate, soil type, compaction, irrigation rate prior, etc.) are shaped at least three CPs for every moisture content, compacted using miniature cylinders (50 × 50) or modified Marshall (100 × 50). This paper proposes a methodology for expeditious evaluation of priming alternative binders to reduce the time and amount of sample. Therefore, test samples were molded in capsules 43mm in diameter and 22mm in height in a sample of sandy soil, using the conventional binder type CM-30. The molding was performed using a coesimetro for compaction the soil in the capsule. It was found that the proposed method can be a simple, fast and inexpensive evaluation of the penetration of bituminous priming and can contribute to the previous selection of alternative binders.
