Adaptive BCI Based on Software Agents

Adaptive BCI Based on Software Agents

The selection of features is generally the most difficult field to model in BCIs. Therefore, time and effort are invested in individual feature selection prior to data set training. Another great difficulty regarding the model of the BCI topology is the brain signal variability between users. How should this topology be in order to implement a system that can be used by large number of users with an optimal set of features? The proposal presented in this paper allows for obtaining feature reduction and classifier selection based on software agents. The software agents contain Genetic Algorithms (GA) and a cost function. GA used entropy and mutual information to choose the number of features. For the classifier selection a cost function was defined. Success rate and Cohen's Kappa coefficient are used as parameters to evaluate the classifiers performance. The obtained results allow finding a topology represented as a neural model for an adaptive BCI, where the number of the channels, features and the classifier are interrelated. The minimal subset of features and the optimal classifier were obtained with the adaptive BCI. Only three EEG channels were needed to obtain a success rate of 93% for the BCI competition III data set IVa.

This paper presents a new electromagnetic modeling of a via-hole using a Wave Concept Iterative Procedure. There are specific TM modes associated with the insertion of the via-hole influencing the incident and reflected waves, called the "via's modes". The formulation and results are presented considering the influence of one and two via's mode. The advantage of the model presented is the possibility to simulate planar circuits with a layer and a via-hole considering the effects of the field that propagates around the via.

Static resistance measurement of circuit breakers has been a crucial technique to assess the state of contacts, supporting maintenance procedures. However, in many cases, the obtained results do not provide accurate data for correct diagnosis, since the test examines only the main contact. This article discusses the application of the contact dynamic resistance measurement (DRM) in the evaluation of main and arcing contacts. The DRM is a contact resistance test, and the resistance is determined during the opening of contacts, analyzing the main and arcing contacts. The research objective is to get the DRM parameters that can assist in the contacts diagnosis. The obtained results indicate that DRM has presented more qualitative parameters than the static resistance test in the evaluation of contacts. The resistance tests were performed applying a direct current with 300 A of amplitude. © 2014 IEEE.

Cognitive radio is a viable technology for the next generation of wireless communications. The ability to sense the electromagnetic spectrum and to enable vacant bands to other users has been investigated in the past years. One important issue is the use of an efficient spectrum sensing algorithm to monitor the frequency band occupancy. Usually, the effects of fading are overseen in the analysis of those algorithms. This paper aims to evaluate the performance of a spectrum sensing algorithm based on Jarque-Bera test. Rayleigh fading is considered in this paper. Preliminary simulation results are provided, to demonstrate the potential of the proposed strategy.

This paper presents an Ethernet sniffer programmed in ANSI C to export in an on-line way the electroencephalographic (EEG) data acquired with the device BrainNet36®, which is a Brazilian EEG device for clinical and polysomnography purposes. The sniffer proved to be useful for off-line analysis of the EEG and also for on-line applications, as Brain Computer-Interfaces (BCIs). Despite its limitations and packet losses at around 1.7% due to noise, the off-line analysis of the EEG successfully replicated results of the literature regarding the Event-Related (De)Synchronization (ERD/ERS) and Evoked Potentials (EPs) calculated for mental tasks. For on-line applications the sniffer was used to program a single-switch BCI for on-line classification of motor and no motor mental tasks with high success rate. Nowadays, the BrainNet36® device is being used for EEG research at many Brazilian universities, therefore, we hope that this article may encourage on-line applications. Finally, as the sniffer operation is explained here with examples, this text may serve as a reference guide for potential user's. © 2014 IEEE.

Stroke is a leading cause of morbidity and mortality worldwide. In most patients, the stroke causes disabilities that hamper the performance of daily tasks autonomously. The most common clinical features in these individuals are hemiparesis, abnormal gait pattern, muscle spasticity and balance loss. There are several studies about the use of robotic devices in hemiparetic individuals, for example for rehabilitation. The robotic walker developed at UFES/Brazil will be assessed for its applicability, using Surface Electromyography (sEMG) to verify the muscle activation during the gait in individuals with post-stroke hemi-paresis. Preliminary tests are being made with the proposed methodology to analyse the robotic walker, but first using a conventional walker two frontal wheels as assistant gait. Two healthy volunteers performed initially a path without the aid of the walker and then with its aid along a flat straight route. sEMG signals are analyzed in order to assess the muscle activity during the gait. After analyzing the data, the results were compared between the free and assisted gait. With the use of the walker the gait speed in healthy volunteers was reduced and, consequently, changes occurred during activation of the muscles. Changes caused by shifting down are important due to improper adjustment of the height of the walker leads to gait changes. As future work, we intend assess the use of robotic walker in clinical trials.

This paper presents an implementation with mobile robot to generate actions to interact with children with autism. The robot is able to detect the child localization and approach him/her, keeping a safe proximity minimum (interaction distance). The mobile robot is equipped with laser sensor to obtain distances and an embedded control system for the interaction. The implementation allows two modes of interaction, depending on the degree of interaction with the child. The system here developed can help children with autism in the process of social evolution and be a tool for professionals and researchers of the area.

This paper investigates a power shunt filter composed by four standard h-bridge converters, acting in four-wire system. Compared with the usual four-wire shunt filters, the proposed converter permits reducing the dc-link voltages, the harmonic distortion or the switching frequency. Suitable control strategies to adjust the filter currents as well as the three dc-link voltages are presented. The PWM strategy is designed to command the converter according to the reference voltage provided by the controllers. Simulation and experimental results are presented.

This paper presents two six-phase open-end machine conversion systems. They are composed of three three-leg converters connected in series to a six-phase machine with open terminals, in an open-end winding connection. The converters use diodes to replace controlled switches, making the conversion system non-reversible and with a reduced number of controlled components. In this case, the machine must work always as a generator. A study concerning harmonic distortion and semiconductor losses is carried out. PWM and control strategies are developed. Simulation and experimental results in order to test these strategies are presented. © 2014 IEEE.

This paper presents two machine drive system based on a six-phase machine (SPM) and three-leg converters. The machine is composed of two three-phase groups. For the first configuration, one of the groups is connected to a three-leg converter and the other is connected to other two three-leg converters in an open-end winding configuration (see Fig. 4). For the second configuration, one of the groups is connected to a three-leg converter (similar to first one) and the other group is connected to a three-level NPC converter (see Fig. 5). Since the machine two groups are fed differently, the system topology is considered to be hybrid. The purpose of these topologies is to be an alternative configuration, being midway between the conventional six-leg inverter system (see Fig. 1) and the NPC six-leg inverter system (see Fig. 2) and Conventional twelve-leg Open-end inverter system (see Fig. 3). Compared with the conventional six-leg system, the proposed systems permits reducing the power processed by the semiconductor switches and their ratings, the dc-link voltage and the harmonic distortion. On the other hand, the proposed systems constitute less complex alternatives, compared with the open-end and NPC counterparts (see Fig. 3). PWM and control strategies are discussed. Simulation and experimental results are also presented. © 2014 IEEE.
