A case study in hybrid multi-threading and hierarchical reinforcement learning approach for cooperative multi-agent systems
(Institute of Electrical and Electronics Engineers Inc., 2016)This paper describes a case study about a multi-agent system for cooperative tasks, i.e. a mixing color task given three different sources of color. A reinforcement learning approach was performed by the agents, however, ... -
Takeoff vibrations of a jetliner : Simulating possible cause
(2016)This paper is motivated by the jetliner vibrations during the takeoff. Using a gas flow simulation tool, the oscillations of the air around the wing are analyzed. It is pointed out that the flow behind and below the wing ... -
Interoperability in electronic health records through the mediation of ubiquitous user model
(Springer Verlag, 2016)The paradigm of healthcare systems has change from isolated proprietary health records to patient-centric solutions in which government, hospitals and clinics, general practitioners and other stakeholders must cooperate ... -
Machine learning method to establish the connection between age related macular degeneration and some genetic variations
(Springer Verlag, 2016)Medicine research based in machine learning methods allows the improvement of diagnosis in complex diseases. Age related Macular Degeneration (AMD) is one of them. AMD is the leading cause of blindness in the world. It ... -
Paralleling a synchronverter and a PWM-based converter for supplying a microgrid
(Institute of Electrical and Electronics Engineers Inc., 2017)The paper's aim is to present the parallel operation of a synchronverter and a PWM-based inverter in order to feed the load of a microgrid. The main motivation lies on the fact that the power electronics advancements made ... -
Estimation of quantile confidence intervals for queueing systems based on the bootstrap methodology
(Springer, 2017)This paper presents a simple methodology for estimating confidence intervals of quantiles in queueing systems. The paper investigates the actual probability density function of quantile estimators resulting of independent ... -
Interpretability of artificial hydrocarbon networks for breast cancer classification
(Institute of Electrical and Electronics Engineers Inc., 2017)In machine learning, interpretability refers to understand the underlying behavior of the prediction of a model in order to identify diagnosis criteria and/or new rules from its output. Interpretability contributes to ... -
Modeling and control of an interleaved DC-DC multilevel boost converter
(Institute of Electrical and Electronics Engineers Inc., 2017)In this paper we study the modeling and control of an interleaved DC-DC multilevel topology that exhibits a high-voltage gain and a minimum ripple point design. In this configuration, the current ripple cancelation point ... -
Medi-Kit : developing a solution to improve attention on medical treatment
(Institute of Electrical and Electronics Engineers Inc., 2017)Leaving unattended a medical treatment may have consequences, from prolonging a recovery waiting time to mortal circumstances. rent technological solutions have been proposed for this problem, including pillboxes and ... -
Electric wheelchair module : converting a mechanical to an electric wheelchair
(Institute of Electrical and Electronics Engineers Inc., 2017)There is a growing need for transportation, either inside a house or office, as well as in the streets and other public spaces. This constant need is a disadvantage for anyone with some kind of disability, specially those ... -
Can crush : an automated waste compacting system for public areas
(Institute of Electrical and Electronics Engineers Inc., 2017)Overwhelming amount of waste is generated every year globally. This problem has been shown to be significant interenst in solving the waste managament, e.g. land filling is a common practice. However, environmental issues ... -
A novel artificial hydrocarbon networks based value function approximation in hierarchical reinforcement learning
(Springer Verlag, 2017)Reinforcement learning aims to solve the problem of learning optimal or near-optimal decision-making policies for a given domain problem. However, it is known that increasing the dimensionality of the input space (i.e. ... -
Fuzzy-based approach of concept alignment
(Springer Verlag, 2017)The need to share and reuse information has grown in the new era of Internet of things and ubiquitous computing. Researchers in ontology and schema matching use mapping approaches in order to achieve interoperability between ... -
Detection of non-homogeneous cycles in blood flow signals in coronary grafts
(SPIESociety of Photo-optical Instrumentation Engineers, 2017)Quasi-periodic blood flow signals, obtained by means of Doppler ultrasound techniques during graft verification, may be contaminated with random distortions (artifacts not periodical not homogeneous and affecting only some ... -
