Açaí is a fruit very present in the lives of the inhabitants of the state of Pará due to its cultural and biological relevance. This importance is explained in indigenous folklore, in which a legend tells the story of its origin, treating it as a food that saved an entire tribe. But not everything is fantasy, açaí is a food that has many nutritional benefits that have been discovered and explored since the 1990s. This interest produced a growth in the demand for the fruit and its derivatives, resulting in the need for technological solutions in several parts of its productive chain. Thereby, the present work aims to create a mobile application that works as an ad marketplace for the açaí market, optimizing its marketing and bringing ease to its members. For this, it was essential to use the IBGE locations API, which provided the manipulation of the counties of Pará as data for various features of the application. Employing technologies such as Flutter and Firebase, it was possible to produce a product that considers the particularities of the açaí market and has the features to assist in its gaps.

Genetic algorithms are used in a wide range of optimization problems, especially in combinatorial problems, where the search space is, in many occasions, too large for exact methods to achieve optimal solutions. This class of problems bear great importance for mathematical models that reflect real world situations, such as vehicle routing. The goal of this work is to utilize a genetic algorithm to optimize networked linked capacitated vehicles, in this configuration, all passengers and drivers positions are known in every moment. To make this optimization possible, the problem was mathematically modeled using the Capacitated Vehicle Routing Problem (CVRP) as inspiration with alterations reflecting the nature of the network linked capacitated vehicles. After that, this work also compares the obtained performance to a non-optimized route, so that the gain from using this method can be observed.

Photovoltaic energy is a source of sustainable energy that is constantly growing in Brazil and in the world, factors for this growth are the reduction of costs and the continuous increases in electricity tariffs. As its name suggests, it is the generation of electrical energy through light (photo, which comes from the Greek "phos" which means light and voltaic which is derived from "volt" which is the unit of electromotive force). However, although photovoltaic energy is becoming popular, for a part of the population it is still a type of exotic technology, for which information is not easily found. Which can lead lay people, who want to take advantage of this type of technology, to make mistakes when purchasing it. To reduce this lack of information, we developed a platform that makes it possible to compare products related to photovoltaic systems. For the development of this project, we used Adobe XD, VScode, MariaDB and HeidiSQL tools, with these tools it was possible to generate the comparison platform.
