The SaaS functional infrastructure presented is a fully operational commercial service intended to replace the standard desktop setup in a scenario where the ECG sensor is capable of transmitting the data to the cloud.","PeriodicalId":203046,"journal":{"name":"2017 40th International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO)","volume":"880 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127405459","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}

It can be a great tool to improve analytic capabilities in any field, for example marketing analytics, churn prediction, health care, etc. In terms of SNA, network structure is defined by nodes, edges and metrics which quantify the importance or influence of certain nodes in the network or relationship strength between nodes. Algorithms for network metrics calculation are complex and that makes SNA difficult to implement in big data environments on large datasets with many nodes and edges. In this paper we will elaborate how to efficiently and performance wise perform SNA and visualize results of the analysis on large datasets using increasingly popular GraphX and JavaScript libraries.","PeriodicalId":203046,"journal":{"name":"2017 40th International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126707011","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}

There is a wide array of smartphone applications and external hardware capable of analyzing NFC systems and traffic that may enable several types of attacks.

However, due to uncertain and dynamic nature of operational environment, algorithms for autonomous operation might fail. In order to assist the robot, the human operator might need to take control over the robot from remote location. In order to efficiently and safely teleoperate the robot, the operator has to have high degree of situational awareness. This can be achieved with appropriate human-computer interface (HCI), so that the remote environment model constructed with sensor data is presented at appropriate time, and that robot commands can be issued intuitively and easily. In the research, influence of HCI elements on performance of teleoperated mobile robot was studied for several tasks and with several HCI setups. The user study was performed, in which accuracy and speed of completion of given tasks were measured on a real robot. Statistical analysis was performed in order to identify possible setup dependencies. It showed that, in majority of analysed cases and based on introduced metrics, there is no significant difference between the setups, and between the visual control and teleoperation. Finally, conclusions were drawn with emphasis on benefits of information technology in particular case.","PeriodicalId":203046,"journal":{"name":"2017 40th International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO)","volume":"abs/2006.06614 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123710900","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}

A complementary method is the detection of the fetal heart rate with an ultrasound. In this paper, we present and analyze abdominal ECG measurements obtained with a differential ECG body sensor. Abdominal ECG was measured in different months of pregnancy within two subjects: one caring a single fetus and another caring twins. The fetal ECG signal measured on the abdomen during pregnancy is superimposed to the mother's AECG and has a very small amplitude, which is smaller than the amplitude of the mother's ECG in that part of her body. The interference from the power grid is not present in the signal, which is crucial for further analysis. The recordings demonstrate the remarkable potential of the sensor for abdominal ECG measurements.","PeriodicalId":203046,"journal":{"name":"2017 40th International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO)","volume":"2016 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127401002","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}

Graphics clusters can offer the raw computing power needed for such simulations but, due to their physical design and operating mode, introduce a series of challenges that must be overcome, such as efficient distributed rendering and remote visualization and interaction with the simulated scenes.
