Josephson Microwave Sources Applied to Quantum Information Systems

Transfer Matrices Applied to Quantum Dot Systems

Quantum dots in semiconductor systems can be used to increase electron excitation in crystals by introducing intermediate bands betwen the main valence and conduction bands. Using the method of transfer matrices, we investigate how an electron interacts with a spherically symmetric potential well boundary. This result then can be generalized by creating a periodic lattice of similar potential w...

Scenario based technique applied to photovoltaic sources uncertainty

There is an increasing need to forecast power generated by photovoltaic sources in day-ahead power system operation. The electrical energy generated by these renewable sources is an uncertain variable and depends on solar irradiance, which is out of control and depends on climate conditions. The stochastic programming based on various scenarios is an efficient way to deal with such uncertaintie...

Information systems applied to transport improvement

Transport is one of the most relevant elements for the competitiveness of companies and cities. An inadequate transportation system generates high costs and low customer service levels, which ultimately produces a negative economic impact for both. This article presents an overview of the technology tools that are part of the Intelligent Transportation Systems (ITS) used to improve the performa...

Probabilistic Argumentation Systems Applied to Information Retrieval

In this dissertation, a new logical model of information retrieval is developed and evaluated experimentally. This model is built on a general technique for uncertain reasoning called probabilistic argumentation systems (PAS), in which propositional logic and probability theory are combined to represent and handle uncertain knowledge, both in a symbolic and in a numerical way. The logical model...
