Autism Spectrum Disorder (ASD) diagnosis is still based on behavioral criteria through a lengthy and time-consuming process. Much effort is being made to identify brain imaging biomarkers and develop tools that could facilitate its diagnosis. In particular, using Machine Learning classifiers based on resting-state fMRI (rs-fMRI) data is promising,...

Ao longo dos anos, várias ferramentas foram propostas na literatura visando auxiliar e apoiar o ensino de programação, sobretudo em disciplinas introdutórias. Essas ferramentas podem auxiliar o aprendizado dos estudantes ao mesmo tempo em que proporcionam dinamismo e inovação, contribuindo para o aumento da motivação no estudo do tema tratado e, po...

Lack of risk management or its inadequate application is one reason that software development projects fail. Agile methods, which have become increasingly popular, do not offer specific activities to manage risks. We develop and evaluate a tool for managing risks in software development projects that use agile methods. The proposed tool provides a...

Power transmission lines are of great importance for the operation of all sectors of society, such as commerce, industry and public agencies. To ensure reliability and availability of power supply, regular and occasional inspections are conducted, mostly using patrol with binoculars, helicopters or truck cranes. Research is being developed using un...

Vehicles are becoming more intelligent and connected due to the demand for faster, efficient, and safer transportation. For this transformation, it was necessary to increase the amount of data transferred between electronic modules in the vehicular network since it is vital for an intelligent system’s decision-making process. Hundreds of messages t...

Ensinar os conceitos de engenharia de software aplicados à gerência de projetos para estudantes de cursos de computação e áreas afins se apresenta como uma tarefa desafiadora devido a fatores motivacionais e de recursos. A partir desta realidade, buscam-se diferentes metodologias que incentivem o estudo do tema. Esta pesquisa apresenta a experiênci...

The social media exerts an important role in publishing information and newspaper online. The quality of this information and the sentiment analysis might help predict the price of diverse market asset and cause great gains and losses. In this scenario, many researchers have been studying the diverse aspects that influence this area. Recently, cryp...

Currently the Project Management Institute (PMI) estimates that approximately 25% of the world’s Gross Domestic Product (GDP) is spent on projects of various kinds and that about 16.5 million professionals are directly involved in project management worldwide. This volume of projects and changes in the world scenario, increasingly competitive, gene...

This paper proposes the selection of historical cost performance data of processes using the Random Tree classifier and the application of the calculation proposed by [20], to improve the predictability of projects cost. The proposed technique was evaluated through an empirical study, which evaluated the implementation of the proposed technique in...

This article examines the main published works on predictability of cryptocurrencies from a point of view of identifying techniques, algorithms and characteristics that can improve price predictability in cryptocurrencies. This paper presents a systematic mapping of papers and classifies them into categories on type of analysis and techniques. This...

This paper focuses on the viability of using smart contract controlled electronic locks to give access to people by the lock’s owner in locations like hotels, coworking spaces or even their homes. The goal is that the guest rents a property using the lock and receives a temporary digital key according to his reservation which he uses to unlock the...

Risk management contributes to software projects success, but agile software development methods do not o®er speci¯c activities to manage risks. Therefore, this study aims to propose a list of risk management practices for agile projects, aiming to increase their chances of success. We analyzed 129 works on agile methods that a®orded 127 risk manag...

O presente trabalho faz uma proposta que combina a técnica de GVA com dados históricos e a utilização da Random Tree com o objetivo de melhorar a previsibilidade dos custos dos projetos, através de um estudo que utilizou 23 projetos de uma fábrica de softwares. Para provar que a técnica proposta era mais precisa que a técnica tradicional, foram rea...

O uso de jogos sérios tem se apresentado como uma estratégia diferenciada para promover o ensino de conceitos e técnicas essenciais a variadas áreas do conhecimento. Visando contribuir para o processo de formação de estudantes de Gerência de Projetos de Software, esta pesquisa apresenta o desenvolvimento e a validação de um jogo sério de tabuleiro...

One of the reasons for the failure of software projects is the absence of risk management procedures or its improper application. The adoption of Scrum in software projects is increasing. However, such approach does not specify risk management activities. This paper presents the results of a survey conducted using a qualitative approach to analyze...

The adoption of the Scrum framework is growing in order to increase the success rate of software development projects. However, the risk treatment in Scrum is performed implicitly. In addition, the scientific literature on this topic is scarce. This study aims to identify and analyze the risk treatment practices proposed by Scrum. The research meth...

Although the Earned Value Management (EVM) technique has been used by several companies in various industrial sectors (software development, construction, aerospace, aeronautics, among others) for over 35 years to predict time and cost outcomes, many studies have found vulnerabilities, including: (i) cost performance data do not always have normal...

The present study proposes an extension of the Earned Value Management (EVM) technique, through the integration of the quality historic data as a mean of improving the technique's cost predictability. The proposed technique was evaluated and compared to the traditional technique in different hypothesis tests utilizing real data of 20 projects. The...

Although the Earned Value Management - EVM technique is utilized by several companies in different sectors for over 35 years, in order to predict cost results, many studies detected vulnerabilities in the technique, among them: (i) there is instability in the cost and time performance indicators during the Project; (ii) there is a trend of deterior...
