This last one is complex and depends on many factors: Position of heart, thickness of the body skin, surface electrode conductivity, acquisition noise and many others. In clinical use, the ECG signal is analysed using twelve leads but in many works in the literature, the analysis methods of the ECG is based on two leads. We present a new method to delineate QRS complexes and T and P waves from electrocardiogram signal. It is based on the continuous wavelet transform. The method is applied on several leads, recorded simultaneously, to improve the localization of the detection. Indeed, if a delineation method is applied on only one lead with some disturbances in it, the result of the delineation could be affected. As the method proposed here merges the result of several leads, the delineation is less affected by disturbances on few leads. The results from this method and from a doctor in medicine are compared. That shows the good ability to separate waves and the enhancement of delineation accuracy when several leads are used.","PeriodicalId":414016,"journal":{"name":"International Conference on Complex Information Systems","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133460513","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}

To turn such information into knowledge , it is necessary to address several information-model issues. Biodiversity data are collected for various scientific objectives, often even without clear preliminary objectives, may follow different taxonomy standards and organization logic, and be held in multiple file formats and utilising a variety of database technologies. This paper presents a graph catalogue model for the metadata management of biodiversity databases. It explores the possible operation of data mining and visualization to guide the analysis of heterogeneous biodiversity data. In particular, we would propose contributions to the problems of (1) the analysis of heterogeneous distributed data found across different databases, (2) the identification of matches and approximations between data sets, and (3) the identificaton of relationships between various databases. This paper describes a proof of concept of an infrastructure testbed and its basic operations, presenting an evaluation of the resulting system in comparison with the ideal expectations of the ecologist.","PeriodicalId":414016,"journal":{"name":"International Conference on Complex Information Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130035867","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}

Processes involving knowledge have these features. The intrinsic characteristic of knowledge is represented by the value that it can generate in a network, due to its constant and continuous rate of growth. In a heterogeneous network not all the nodes have similar knowledge levels. Furthermore, not all the connections have the same importance. In order to consider knowledge as a resource and not as an obstacle, it is admittable that nodes can decide individually with whom transfer knowledge. Using a context-aware decision making perspective and considering each single node as a decision maker that has to decide in a particular context whether accept the transfer or not, it will be helpful to understand how and why certain mechanisms and behavioural patterns arise. In this paper, the proposed model considers the process of knowledge transfer as a decision making one, where each alternative, one of the nodes neighbor that wants to transfer knowledge, has an evaluation on the basis of two criteria, knowledge distance and confidence. Their values are dynamically updated at each time step on the basis of the quality of the knowledge transferred.","PeriodicalId":414016,"journal":{"name":"International Conference on Complex Information Systems","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115730955","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 relatively recent times, the availability of data regarding human movements have fostered the emergence of a new branch of social studies, with the aim to unveil and study those patterns thanks to data collected by means of geolocalization technologies. In this paper we analyze a large dataset of GPS tracks of cars collected in Rome (Italy). Dividing the drivers in classes according to the number of trips they perform in a day, we show that the sequence of the traveled space connecting two consecutive stops shows a precise behavior so that the shortest trips are performed at the middle of the sequence, when the longest occur at the beginning and at the end when drivers head back home. We show that this behavior is consistent with the idea of an optimization process in which the total travel time is minimized, under the effect of spatial constraints so that the starting points is on the border of the space in which the dynamics takes place.","PeriodicalId":414016,"journal":{"name":"International Conference on Complex Information Systems","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116507577","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}
