The way citizens interact with cities affects overall life quality. Their participation in social decisions is of paramount importance for helping on public decisions that affect governance, regulation and education. This interaction has the potential of being boosted within the scope of smart and digital cities, especially by recent advances in bl...

Cities are constantly transforming and, consequently, attracting efforts from researchers and opportunities to the industry. New transportation systems are being built in order to meet sustainability and efficiency criteria, as well as being adapted to the current possibilities. Moreover, citizens are becoming aware about the power and possibilitie...
Chapter
A global trend has been motivating programmers, investors, and the academia to go towards decentralized systems. Besides providing efficient solutions for complex problems faced in our daily life, these peer-to-peer communication protocols have been promoting greater freedom and transparency. In this paper, we point out open fields for researching,...
Chapter
Cities are undergoing transformations in several respects, but, mainly, regarding novel technologies. In this sense, the aim of this study is to understand the relation between the cities and the use of emerging technologies such as digital democracy, blockchain and, in particular, smart contracts. To discuss and analyze the possibilities of this e...

Purpose Universities, as providers of knowledge and technology, have a key role in society based on knowledge. The purpose of this paper is to identify and describe the technological innovation centers (TICs) of the federal universities of Minas Gerais, Brazil, verifying if federal institutions of higher education in the state are meeting the attr...
Conference Paper
Full-text available
The smart city debate will still be the scope of business, policy-making and territorial planning in the following years. Based on that, the paper aims to propose an interdisciplinary conceptualization of smart territories. The goal is to promote the contrary movement of megacities creation and also consolidate the geographical aspect of smartness....

A constante evolução das cidades tem impulsionado o desenvolvimento de novas fer-ramentas para integração entre os cidadãos. Aplicações inspiradas em técnicas da pesquisa ope-racional, que auxiliam a tomada de decisão, podem tornar viáveis antigos sonhos já idealizados por filósofos. Dentre esses, destacamos sistemas judiciais mais participativos,...

Distintos são os desafios para engajar os cidadãos em decisões sociais. As Tecnologias da Informação e Comunicação (TIC) possuem potencial para aprimorar tais relações, tornando os sistemas das cidades mais digitais. Este trabalho investiga a utilização dessas ferramentas nas cida- des inteligentes, do inglês Smart Cities (SC). Com o foco em otimiz...

Brain activity can be seen as a time series, in particular, electroencephalogram (EEG) can measure it over a specific time period. In this regard, brain fingerprinting can be subjected to be learned by machine learning techniques. These models have been advocated as EEG-based biometric systems. In this study, we apply a recent Hybrid Focasting Mode...

This paper focuses on Book Marketing Campaigns, where the benefit of offering each book is calculated based on a bipartite graph (biclique). A quasi Biclique problem is assessed for obtaining the probabilities of success of a given client buy a given book, considering it had received another book as free offer. The remaining optimization decision p...

This paper presents an Evolution Strategy (ES) based algorithm, designed to self-adapt its mutation operators, guiding the search into the solution space using a Self-Adaptive Reduced Variable Neighborhood Search procedure. In view of the specific local search operators for each individual, the proposed population-based approach also fits into the...

This paper focuses on the targeted offers problem in direct marketing campaigns. The main objective is to maximize the feedback of customers purchases, offering products for the set of customers with the highest probability of positively accepting the offer and, at the same time, minimizing the operational costs of the campaign. Given the combinato...

Project
This project aims to develop efficient algorithms for solving combinatorial optimization problems, such as vehicle routing, timetabling, classroom assignment, open-pit-mining operational planning, timetabling, scheduling, warehouse picking, etc. In particular, most of our research studies have been focusing on the use of metaheuristic-based algorithms. However, mathematical programming formulations and matheuristics are also in this research line's scope.
Project
This projects consider power dispatching in the future mini/microgrids scenarios. In particular, several operational requirements and constraints of the future cities are taken into account.
