In this study, we propose a novel P300 BCI paradigm for spelling through auditory-tactile bimodal stimuli. The target number of speller is increased and thus the information transfer rate (ITR) is improved. Specifically, a BCI speller with 36 selectable items was developed by simultaneously and randomly presenting auditory and tactile stimuli from same one of six directions. With six participants, the average simulated online ITR of the bimodal-stimulus-BCI system increased by 30% and 34% compared with the auditory and tactile approach, respectively. These findings suggest the proposed bimodal BCI paradigm is exceedingly efficient, which is promising for achieving quick spelling in visual saccade-independent P300-BCI application.","PeriodicalId":293990,"journal":{"name":"2019 IEEE International Conference on Computational Intelligence and Virtual Environments for Measurement Systems and Applications (CIVEMSA)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114382744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The problem of multi-agent is that each of the agents has a randomly different initial state. The existence of multi-agent in a system needs to be managed in order to be a structured system for making certain decision cooperatively. This paper presents the implementation of cooperative multi-agent for synchronizing the end-effector position of the robotic arm based on consensus and PID controller. Physically, the robotic arm has three servo motors that mean the robotic arm has three joints. Thus, to synchronize the end-effector position of the robotic arm among agents, all of the servo motors in all agents must be controlled in order to achieve the same point of view. In addition, this paper expounds how to derive the consensus equations and PID controller based on designed graph topology. The presence of two proposed methods is intended to compare whether or not the problem of multi-agent regarding randomly different initial state can be overcome by using consensus and PID controller. From the experimental results, the derived consensus equations and PID controller can be implemented to synchronize all of the joints possessed by the robotic arm. As a result, the end-effector of the robotic arm in all of the agents successfully pointed to the same position in three-dimensional space. It indicates that the derived consensus equations and PID controller can handle the different state of each joint in all of the agents.","PeriodicalId":293990,"journal":{"name":"2019 IEEE International Conference on Computational Intelligence and Virtual Environments for Measurement Systems and Applications (CIVEMSA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129496531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, the path planning task is carried out using three bio-inspired optimization algorithms, including PSO, ABC and FA. The duty of the algorithms is to determine a collision-free path through fixed obstacles in the working environment. The maximum speed of the robot is applied to the optimization problem as a constraint. In order to evaluate the performance of the algorithms, four workspaces with different obstacle layout are simulated in MATLAB, and the quality of path planning task is analyzed statistically and numerically, considering four different criteria, including, convergency quality, convergency time, path length and success rate. In the next step, a control model is designed to track the path curve determined by the path planning algorithms. A PID-based control structure is simulated in MATLAB Simulink and the controller was able to track the pre-determined traj ectories with proper approximation. The controller is applied on a dynamic model of a two-wheeled mobile robot offered by [1]. In order to validate the control inputs it is necessary to apply them on a real platform. The experimental study is implemented on a two-wheeled mobile robot which is designed and built based on the authors' previous paper [2] in various enverioment and obstacles. The result shows control inputs were applied to the real robot and the robot was able to imitate the applied path curve, and find its way toward the target point without colliding obstacles in real and simulation task.","PeriodicalId":293990,"journal":{"name":"2019 IEEE International Conference on Computational Intelligence and Virtual Environments for Measurement Systems and Applications (CIVEMSA)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132014033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most methods applied to decode SSVEPs are limited to CCA and some extended CCA-based methods. This study proposed a comparing network based on Convolutional Neural Network (CNN), which was used to learn the relationship between EEG signals and the templates corresponding to each stimulus frequency of SSVEPs. This novel method incorporated prior knowledge and a spatial filter (task related component analysis, TRCA) to enhance detection of SSVEPs. The effectiveness of the proposed method was validated by comparing it with the standard CCA and other state-of-the art methods for decoding SSVEPs (i.e., CNN and TRCA) on the actual SSVEP datasets collected from 17 subjects. The comparison results indicated that the CNN-based comparing network significantly could significantly improve the classification accuracy compared with the standard CCA, TRCA and CNN. Furthermore, the comparing network with TRCA achieved the best performance among three methods based on comparing network with the averaged accuracy of 84.57% (data length: 2s) and 70.21% (data length: 1s). The study validated the efficiency of the proposed CNN-based comparing methods in decoding SSVEPs.

Many studies have used electroencephalograph (EEG) technology for CI users, which have shown that EEG is suitable for clinical postoperative evaluation. This study aims to explore changes of latencies and amplitudes of P1 wave in CI children under auditory stimulation. A pure tone at 1000 Hz was used as the stimuli to induce cortical auditory evoked potentials (CAEP). The characteristics of P1 wave were compared between normal hearing children and CI children over different implantation period. Results show that CI children started to have improved auditory perception after implantation, moreover, their P1 wave amplitude becomes similar to that of normal hearing children after six months. One year after implantation, the characteristics of P1 wave of CI children become similar to those of normal hearing children. Therefore, it seems that P1 could be used as an objective auditory rehabilitation assessing indicator for CI children.","PeriodicalId":293990,"journal":{"name":"2019 IEEE International Conference on Computational Intelligence and Virtual Environments for Measurement Systems and Applications (CIVEMSA)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122228872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Generally, voice signals are used for speech recognition, which is easily affected by environmental interference. Additionally, surface electromyography (sEMG) of articulatory muscles has been proposed in previous studies to enable speech recognition, which is insensitive to noisy environments. However, it remains unclear what are the contributions of facial and neck muscles for speech recognition, which would be vital for selecting locations of sEMG recording electrodes. In this study, the high-density (HD) sEMG technique was proposed to explore the major articulatory muscles contributed to speaking. The HD sEMG signals were acquired from four subjects by surface electrodes over the face and neck during speaking five Chinese daily phrases, from which four features (mean absolute value, waveform length, number of zero crossing, and slope sign change) were extracted. Then a linear-discriminant-analysis classifier was built by the sEMG features for speech recognition. The primary results showed that the sEMG and RMS waveforms illustrated obvious difference when speaking different Chinese phrases. And the classification accuracy using signals from the neck was higher than that from the facial muscles, whereas the accuracy was increased by using the whole facial and neck muscles. Our pilot results revealed that the facial and neck muscles were both contributed to the speech recognition while the neck muscles were more crucial than the facial muscles during speaking. This pilot study may suggest that the HD sEMG might pave a way to find the major muscles of speech recognition.","PeriodicalId":293990,"journal":{"name":"2019 IEEE International Conference on Computational Intelligence and Virtual Environments for Measurement Systems and Applications (CIVEMSA)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131808770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nowadays, Convolutional Neural Network (CNN) and its related CNN-hybrid approaches have achieved the state-of-art accuracy in this field. However, most of these existing techniques employ large-scale neural networks which cause performance bottleneck in portable systems. Moreover, traditional convolution kernel confuses EEG multiple frequency bands information, which is critical for investigating emotion status. To improve these issues, firstly, we extract power spectral features from four frequency bands (θ,α,β,γ) and transform obtained features into cortex-like frames while preserving spatial information of electrodes position, so that the multi-channel, multi-frequency bands and time series EEG signals can be efficiently represented. Then, we design a shallow depthwise parallel CNN inspired by Mobilenet technique to learn spatial representation from labeled frames. Segment-level emotion recognition experiments are implemented to verify the proposed architecture with DEAP database. Our approach achieves the competitive accuracy of 84.07% and 82.95% on arousal and valence respectively. Besides, the experimental results prove the computation-effectiveness of the proposed method. Compared with the state-of-art approach, our approach saves 69.23% GPU memory and reduces 30% GPU peak utilization with only 6.5% accuracy drop.

However, in practice, sensor isolation is a state of normality, and full connectivity is not a requirement for many WSN applications to operate successfully. Due to this, this paper investigates the partial connectivity problem in a randomly deployed WSN, taking into consideration the particular function of the sink node and its skewed placement due to environmental and terrain factors in network deployment. We strive to identify the tradeoffs between partial connectivity and the required network parameters in contrast to full connectivity under various circumstances. Through mathematically modeling, theoretical analysis and simulation evaluations, we demonstrate the significant impact of the sink node and its placement on the network connectivity and that partial connectivity, as compared with full connectivity, is a more appropriate metric to assess the connectivity of random WSNs. For example, we show that the sensor connection rate drops from 98.8% to 72.5% when the sink node is relocated from the network center to the border and that 1.367 times more energy is needed to connect less than 4% of the remote sensors, under the studied network settings. The results help in defining appropriate performance metrics and in selecting critical network parameters for real-life WSN design and implementation.","PeriodicalId":293990,"journal":{"name":"2019 IEEE International Conference on Computational Intelligence and Virtual Environments for Measurement Systems and Applications (CIVEMSA)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124734009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
