The purpose of this article is to evaluate the feasibility of parameterization of custom basic molds, eliminating the need for making a mold for each user. This method uses the three-dimensional scanning to obtain the anthropometric measurements, and the user’s body silhouette and parameterize these measures, causing the production of a single basic mold is necessary to meet users with different anthropometric characteristics. A low-cost 3D scanner was used, Microsoft Kinect, to obtain the 3D model of the user’s body and the Grasshopper modeling algorithm for setting the mold. Thus, a research participant was scanned and, from your 3D model, anthropometric measurements were obtained for setting the mold. The final model was built and experienced by the participant for validation purposes. The results were satisfactory in showing high precision in anthropometric model produced. Thus, the study addressed brings important contribution to the development of products for clothing in areas as they provide flexibility in the basic mold production process and product measurements with high accuracy and hence increase the degree of comfort for the user.

O objetivo deste trabalho, que é o recorte de uma pesquisa em andamento, é analisar materiais compósitos e sugerir a substituição da madeira natural em playgrounds por essa matéria-prima. Esses compósitos, conhecidos como materiais verdes, combinam fibras naturais com polímeros biodegradáveis, sendo eles sustentáveis, ou seja, de fácil compostagem no final de sua vida útil, sem prejudicar o meio ambiente. A partir de uma investigação laboratorial, com foco 3 (três) materiais compósitos, foram utilizados equipamentos para análise da superfície e composição química do produto. Os resultados demonstram que os 3 (três) materiais podem substituir a madeira natural, devido à sua resistência e durabilidade, porém, necessita-se de mais ensaios para verificar a viabilidade quanto ao processo de usinagem de peças para os equipamentos de playground.

This paper discusses an automated approach to database change management throughout the companies’ development workflow. By using automated tools, companies can avoid common issues related to manual database deployments. This work was motivated by analyzing usual problems within organizations, mostly originated from manual interventions that may result in systems disruptions and production incidents. In addition to practices of continuous integration and continuous delivery, the current paper describes a case study in which a suggested pipeline is implemented in order to reduce the deployment times and decrease incidents due to ineffective data controlling.

This work presents the HyperCAL3D, an application to support the teaching and learning process of Descriptive Geometry through the study of solid objects. The methodology used for its implementation and the main features of the application are described. A selection of concepts was carried out to determine the functional structure of the software should have. From this, the main features were modeled through processes of vector geometry equivalent to that used in Descriptive Geometry. The main features introduced include: the projection process, the representation of hidden lines in three-dimensional model and the projections, successive auxiliary views in real time, and the intersection process. All these tools are implemented in an application that aids the learning process of the students and the teaching procedures of professors.
