Conference Paper
Although there is a growing concern about accidents and illnesses at work, global statistics still reveal alarming data. It is estimated that 2.78 million people die each year worldwide due to labor factors. In this regard, information systems and automation systems applied to occupational health and safety are gaining prominence for accident preve...

The heat input is the amount of energy supplied per unit length of the welded workpiece. In this study, the effect of two different heat inputs in laser beam welding of a high strength aluminum alloy AA6013-T4 was evaluated from macrostructural and microstructural points of view. The experiments were performed using a continuous wave 2 kW Yb-fiber...

This paper focus on the learning of music time series. In this context, from compressed digital audio files, we sought to verify how a song can be learned, both in terms of amplitude and frequency. Given the enormous amount of data contained in those time series, the use of classical learning methods becomes limited. Typical compressed acquisitions...

The adhesion between carbon fiber-reinforced polymer (CFRP) and titanium parts can be improved by laser surface texturing before gluing them together. Here, a pulsed Nd:YAG laser was employed before bonding of the textured surfaces using an epoxy paste adhesive. To investigate the influence of the laser parameters, the roughness of the surfaces wer...

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...

In this paper, a multi-objective power dispatching problem that uses Plug-in Electric Vehicle (PEV) as storage units is considered. The problem involves several PEVs and a microgrid community, composed of small houses, residential areas, and different Renewable Energy Resources. Three different objectives are considered: microgrid total costs; usag...

This paper describes a multi-objective power dispatching problem that uses Plug-in Electric Vehicle (PEV) as storage units. We formulate the energy storage planning as a Mixed-Integer Linear Programming (MILP) problem, respecting PEV requirements, minimizing three different objectives and analyzing three different criteria. Two novel cost-to-variab...

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...
Conference Paper
Improving the use of energy resources has been a great challenge in the last years. A new complex scenario involving a decentralized bidirectional communication between energy suppliers, distribution system and consumption is nowa-days becoming reality. Sometimes cited as the largest and most complex machine ever built, Electric Grids (EG) are been...
Article
The importance of short-term load forecasting has been increasing lately. Electric grids are changing from a centralized single supply model towards a decentralized bidirectional grid of suppliers and consumers in an uncertain and very dynamic scenario. On the other hand, with deregulation and competition, energy price forecasting has become a big...

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.
