This clinical method is cheap and effective and requires professional doctors to understand and interpret the heart sound for diagnosis of cardiac diseases. This paper presents basic analysis and comparison of heart sounds recorded from healthy and unhealthy subjects for automated screening of cardiac disorders. Some characteristics of heart sounds such as probability distribution of amplitude and frequency contents are quantified using signal processing to automate the diagnosis of cardiac disorders. Experiments were carried on the Heart sounds database created under National Institute of Health (National Center for Research Resources) and results are encouraging. The experiment results indicates enough discrimination between heart sounds from healthy and unhealthy heart sounds for automated screening of cardiac disorders using signal processing.","PeriodicalId":126751,"journal":{"name":"2017 International Conference and Workshop on Bioinspired Intelligence (IWOBI)","volume":"127 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123439870","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}

Such first module consists in the temporal segmentation of television video broadcasts, aiming to break down the video into shots, delimited by scene boundaries. An evaluation of other seven histogram distances is proposed, thus in order to better justify the use of the Bhattacharyya distance in ACE. Results presented were obtained using matches of the FIFA World Cup 2014. The classification results obtained by using Bhattacharyya distance are indeed the highest in terms of the F1-score, this was the main contribution of this study as there is no previous evidence of Bhattacharyya distance being compared with other distances and hence being selected as the one that produces the best classification results for our application.","PeriodicalId":126751,"journal":{"name":"2017 International Conference and Workshop on Bioinspired Intelligence (IWOBI)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123764758","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}

These marks could be used to detect early symptoms and monitor the evolution of the disease in time. Classically articulation marks have been mainly based on static premises. Articulation Kinematics from acoustic correlates may help in producing measurements based on the dynamic behavior of speech. Specifically, distribution functions from the absolute kinematic velocity estimated by a simplified articulation model can be used in establishing distances based on Information Theory concepts between running speech segments from patients and controls. As an example, a longitudinal case of ALS has been studied using this methodology. It shows that the performance of dynamic articulation quality correlates may be more sensitive and robust than static ones. Conclusions foresee the use of speech as a valuable monitoring methodology for ALS timely evolution.","PeriodicalId":126751,"journal":{"name":"2017 International Conference and Workshop on Bioinspired Intelligence (IWOBI)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121494369","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}

This article proposes a methodology for artificially generating a bipedal humanoid gait pattern for the knee and hip leg joints in the sagittal plane. The lower limbs movement is divided into three complementary patterns of movement, each with a specific function, which can be modulated individually and superposed to compose a gait pattern. This strategy is based on the potential field navigation algorithm concept [1] and the architecture for its application is based on the AuRA cognitive architecture [2]. The methodology was validated using a MATLABTM implementation of a simplified kinematic model of the legs movements. The results show movement patterns close to the biomechanical ones at the joints. When applied to the kinematic model, those movement patterns generate feet trajectories that are consistent to the biomechanical gait both in shape and amplitude. The strategy was also embedded in a microcontrolled prototype, revealing low computational demands as well as another view for the generated movement.","PeriodicalId":126751,"journal":{"name":"2017 International Conference and Workshop on Bioinspired Intelligence (IWOBI)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127411906","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}

No mortality was observed during the 2 weeks experimental period. The SE of the experimental cases was modified by the presence of MeHg, confirming our previous works.
