Abstract: This work presents the development of a web application focused on Progressive Web Apps (PWA), for sharing the prices of products targeted by region. The system also has intrinsic crowdsourcing methodologies based on the use of rewards, based on evolving User Profile categories, with exclusive features. In the developed solution, a recommendation algorithm based on collaborative product filtering was used. The results obtained from tests with users became satisfactory, showing good usability, acceptance and operation of the developed application, as well as indicating future strategies to improve the usability of the proposal for other audiences, studies of new layouts and specific profiles for categories of users.

Abstract: In this work, the objective was to develop a digitizer, in the form of web application, to extract world coordinates from images of XY-type graphs with Cartesian axes represented in linear scales. The analysis of 13 digitizing tools served as a basis for the implementation of some functionalities such as the display of statistical parameters associated with the definition of scale, as well as improvements in the definition of control points, which contributes to the configuration of more reliable scales and, consequently, more results accurate. The mathematical model used to adjust the scale equations was the same to perform linear geometric transformations affine in the plane and, to validate it, a unit radius circumference contained in an image transformed by shear and then by rotation was digitized. The statistical analysis showed excellent results, which allow us to conclude that the mathematical model was used correctly.

Abstract: Nowadays, digital technologies and internet access are part of most people's lives. The expansion of the internet combined with new development tools in programming has allowed the community development of applications to solve the most varied urban problems. This work describes the implementation of a web platform for the dissemination of applications based on civic technologies, through open-source community development in Mato Grosso do Sul, entitled “Code for Pantanal” project. Such a platform is being conceived through the use of open source tools, and the back-end is with a NodeJS API using the ExpressJS framework that is linking the database in MongoDB, reporting Json to the front-end in ReactJS. Among the functionalities developed are: i) visualization of registered projects, ii) request to participate in a project, iii) indication for new projects, iv) summary of project documentation, v) information about the team, vi) didactic material, including tutorials and video lessons on projects, sharing source code and first steps in programming. The project, in addition to educating the authors' training in technology, proves to be of great contribution to society, since there is the possibility of this project shortening the relationship between the community and municipal entities, accelerating the response to solve urban problems.
