    Inferência baseada em regras de produção para o diagnóstico laboratorial da anemia
    (Centro Universitário do Estado do Pará, 2018-06-11) Gouveia, Rafael Santos; Rocha, Thiago Maia da; Nascimento, Polyana Santos Fonseca; Bezerra, Deisiany Santos; http://lattes.cnpq.br/6889523334917369; Araújo, Andrea Cristina Marques de; http://lattes.cnpq.br/7322421741765559
    Artificial intelligence is a technology that presents relevant applications in several areas. Soon after the emergence of this technology, its usefulness in the field of medicine stood out, culminating in notorious results regarding clinical process aid and long-term financial return. When dealing with the medical diagnostic procedure, the large number of variables can affect the decision process, causing differences in the opinions of the practitioners. There are many uncertainties regarding risk factors, therefore the diagnosis of the disease can be difficult even for specialists. Aiming in creating a tool to support the laboratory diagnosis of anemia, this project carried out a study that combined concepts in hematology with artificial intelligence under the approach of knowledge based systems to develop an inference system prototype that supports the process of diagnosis. This study also presents reports about the system development process. Consequently, it was possible to study anemia diagnosis and how to apply the acquired knowledge to the computational language and formal representation of the problem. As a result, it was possible to understand the stages which are part in a medical área knowledge based system development.

    Técnicas anti-forenses em computadores pessoais
    (Centro Universitário do Estado do Pará, 2017-12-04) Macêdo, Wilson Antonio Cosmo; Brito, Itamar Jorge Vilhena de; http://lattes.cnpq.br/5143837732124006; Araújo, Andrea Cristina Marques de; http://lattes.cnpq.br/7322421741765559; Carmo, Ricardo Melo Casseb do; http://lattes.cnpq.br/4933624262290855
    The evolution of information technologies and the increase of users in the digital environment also resulted in the increase of the number of crimes in the virtual environment, as well as the complexity of them, thus creating new challenges for the professionals involved in the computer forensics. The purpose of this study is precisely to analyze the forms that malicious users with personal computers can use to try to obstruct the expert analysis in case of suspect of crim, either by hiding or destroying data, so that the information obtained during the analyzes of this work may help in cases where the presence of any of these techniques. The approach used to carry out the study was the use of simulations of some of these techniques in a controlled environment close to the real scenario and the use of tools focused on expertise and digital research in these scenarios to evaluate the efficiency and main characteristics of these techniques, generating in this way technical information that may provide an advantage to the expert or digital investigator in cases with simliar occurrences to those present in this study.
