(Centro Universitário do Estado do Pará, 2018-06-11) Sousa, Luiz Fellipe dos Santos; Brito, Itamar Jorge Vilhena de; Rocha, Raphael Souza; http://lattes.cnpq.br/6636943649993665; http://lattes.cnpq.br/5143837732124006; Baganha, Alessandra Natasha Alcântara Barreiros; http://lattes.cnpq.br/0672275617505946
This monograph deals with MKBlack: a heated bed for a 3D printer, emphasizing by means of comparative tests two models of heated bed, one with the pattern of circuit and heating, of commercial model most used in the market and the model proposed by the present work: to MKBlack. This shows a differentiated circuit pattern and, consequently, unusual heating in relation to the current market, thus emphasizing the decrease in 3D printing failures, usually caused by non-heating or poor heating of the heated bed. In the same tuning fork, it was emphasized that even the most widely used model on the market still needs significant changes and improvements. Since the MK2b model is Open Source, it was possible to use it as a principle for the development of the MKBlack heat bed, tested and approved satisfactorily. Such print tests have shown the possibility of printing parts of greater complexity, size and in different forms, therefore generating a large variety of parts in the production process that did not occur warping, as proven in the heating tests.

The need for the introduction of renewable energy sources is becoming greater, due to strong droughts that the country has been passing the water reserves responsible for supplying hydroelectric plants, which at some times of the year become unable to supply the electricity supply of some cities. Based on this, solar energy projects have been gaining ground in the market and have become more popular over time. The biggest drawback to joining a system of this type is the high cost of investment, but the financial result begins to appear gradually over the years, since this return will come with the reduction of the amount to be paid in the energy bill. Designing a photovoltaic system for a company that depends on high demand for electrical energy requires a large area required for the application of the modules, if a large space is not available the project could be hybridized, where conventional electric energy will work with the energy photovoltaic electricity.

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.

As time goes by, we realize that technology’s evolution is very consistent in society and our life. One of the branches that has grown in this period was in the commercial area, with new payment options (like credit card, debit card, internet banking, among other choices). However, this progress has positive and negative points. One of the negative points one could mention are hackers: people that observe and use system’s weakness for self-benefit. There are many reasons why hackers do it, for instance, for self-realization and financial return. Credit card utilization is getting more frequent each day due to commercial transactions by mobile devices. Information security needs to increase in order to prevent credit card cloning and other forms of cyber-attacks. This study aims to build a methodology using hardware and software. The purpose is to increase security in credit and debit card transactions, minimizing infrastructure related problems, like credit card cloning. Cryptography transactions and artificial intelligence (Pattern Recognitions) applied to authentication multi protocols will be studied. We will also look at improving authentication to increase the security. Cryptography will be used to protect the client’s data along the way. Pattern recognition is the knowledge used to classify and recognize in and out information in a credit card machine, like digital impression, iris and voice patterns.
