To set up a network with a large number of devices in the constrained environment can be a challenge. Also, collecting, storing and analyzing data generated from sensors attached to the devices most often requires developing custom-made applications which imply time and cost consumption. Several cloud providers are offering IoT services that unite needed features into full solution offering connectivity between devices and the cloud, processing of data sent from devices and interaction with connected devices through the application. One of them is AWS IoT (Amazon Internet of Things) which is fully scalable, reliable and simple to use. This platform can collect data from a large number of different devices and connect them to endpoints for other tools, allowing a developer to tie received data into the independent application. Other aspects, like security, resource management, integration and centralized management are also covered. In this paper, we will evaluate the performance of the AWS IoT web services by connecting small, single-board computers, like Raspberry Pi through different scenarios.","PeriodicalId":431110,"journal":{"name":"2018 41st International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126642464","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 aim of this paper is to present an analytical model for the planning and use of network resources in the heterogeneous networks (multitier, multistandard) whose topology will enable network enhancements of indoor and outdoor coverage, capacities and reliability of communication, reduction of investment costs and maintenance of the network, as well as reduction of electricity consumption. This model should set the theoretical framework in which it is possible to upgrade efficiently the existing network with the least costs of network deployment, while at the same time providing the capacity to meet user requirements in the necessary places and at the required time. Accordingly, a set of values of network resource parameters is presented as one of the main results achieved by this model. Hence, this set grasps parameters' values which enable increased energy and spectral efficiency, as well as required capacities, the satisfactory level of quality of service, and rational energy consumption within the real network in the time domain. In addition, the results include the establishment of a connection with the necessary limit values of the radio signal parameters at the cell boundaries, considering all cell tiers.","PeriodicalId":431110,"journal":{"name":"2018 41st International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125650932","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 findings were analyzed in relation to four variables: age and gender of study participants; field of science in which they work; their practices of exchanging scientific literature. The questionnaire was sent to employees at the Faculties of Humanities and Social Sciences, as well as to the employees of various science faculties in Croatian cities Split and Rijeka. It was found out that there are significant differences in use of web portals. More than half of participants from the fields of social sciences and humanities use very frequently Croatian portal Hrčak, in relation to only 4% of participants from the field of natural sciences. For participants in humanities the Croatian portals are most important. Scientists from the field of social sciences mostly use foreign portals. Scientists from the field of natural sciences are the most frequent users of pirate portals. It was established that older participants use most frequently Croatian portals. Younger participants most frequently use foreign and pirate portals. Croatian and foreign web portals are most frequently used by female participants, while male participants are most frequent users of pirate portals.","PeriodicalId":431110,"journal":{"name":"2018 41st International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO)","volume":"31 11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134288256","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}

ECG signal holds vital information for the current health condition of the patient. Detection of cardiac disorders is based on detection of sudden deviations from the mean line. Detection of heartbeat functions is based on extracting ECG characteristic features, especially the R-peak. Although in this paper we address a general approach, we focus on using wearable ECG sensors and developing an efficient QRS detector to determine the heartbeat function. The real problem in detection and ECG signal analysis is processing the noise contaminated ECG signal and the way one can reduce the feature space to extract the relevant features. In this paper, we set a research question to investigate how the filter affects the accuracy, sensitivity and precision values on QRS detectors. We report our findings on optimal filter design with a central frequency of 8.33 Hz and −3db cutoff frequencies at 4 Hz and 20 Hz. The analysis addresses development of an efficient filter with small computing complexity intended to be used for wearable ECG sensors.","PeriodicalId":431110,"journal":{"name":"2018 41st International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133898143","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}

For light at mid-infrared (MIR) wavelengths, metals become less suitable for plasmonic applications as a result of the high Drude losses. At those wavelengths, highly doped semiconductors are potential alternatives. The doped group IV alloy Ge<inf>x</inf>Sn<inf>y</inf> has been shown to be particularly interesting. We present results on the fabrication and optical characterization of rod antennas fabricated from highly n-type doped Ge<inf>0.95</inf>Sn<inf>0.05</inf> (n-Ge<inf>x</inf>Sn<inf>y</inf>) on Si(001) substrates. Extinction spectra were obtained via Fourier Transform Infrared (FTIR) Spectroscopy. To verify the measurement results the behavior of the n-Ge<inf>0.95</inf>Sn<inf>0.05</inf> rod antennas was simulated. The results show that the n-Ge<inf>0.95</inf>Sn<inf>0.05</inf> rod antennas absorb MIR radiation through plasmonic excitation. Two different peaks could be observed in the extinction spectra of the n-Ge<inf>0.95</inf>Sn<inf>0.05</inf> rod antennas and attributed to two locally separated plasmonic modes. One mode forms on the n-Ge<inf>0.95</inf>Sn<inf>0.05</inf>/Si interface of the n-Ge<inf>0.95</inf>Sn<inf>0.05</inf> rod antennas, the other one forms at the n-Ge<inf>0.95</inf>Sn<inf>0.05</inf>/air interface. We discuss possible applications of this type of n-Ge<inf>0.95</inf>Sn<inf>0.05</inf> rod antennas for MIR sensing.","PeriodicalId":431110,"journal":{"name":"2018 41st International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129295865","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 is very important to motivate students to actively participate in classes, regardless of a classical classroom education or e-learning style of teaching. Gamification is one of the methods that motivates students to actively participate in class, learn through entertainment by playing with their colleagues and emphasize on the positive competition and also, to make learning fun. In this paper, some of the methods used by Zagreb School of Economics and Management (ZSEM) will be described and analyzed through student engagement and motivation in different courses. courses that are related to technologies and courses that are related to legal discipline. The research shows that students are very pleased with the introduction of gamification as part of the educational process — no matter which course it is, they feel that gamification has helped them to get motivated to study and they have expressed their wish to have it as part of any course they are attending.","PeriodicalId":431110,"journal":{"name":"2018 41st International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO)","volume":"449 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115920819","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}
