However, these IoT solutions face the big data challenge where data comes with a certain velocity and huge quantities. In this paper, we analyze a situation where wearable ECG sensors stream continuous data to the servers. A server needs to receive these streams from a lot of sensors and needs to star various digital signal processing techniques initiating huge processing demands. Our focus in this paper is on optimizing the sequential Wavelet Transform filter. Due to the highly dependent structure of the transformation procedure we propose several optimization techniques for efficient parallelization. We set a hypothesis that optimizing the DWT initialization and processing part can yield a faster code. In this paper, we have provided several experiments to test the validity of this hypothesis by using OpenMP for parallelization. Our analysis shows that proposed techniques can optimize the sequential version of the code.","PeriodicalId":203046,"journal":{"name":"2017 40th International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO)","volume":"33 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":"125034511","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 course is obligatory for sophomore students enrolled in Electrical Engineering and Information Technology undergraduate program as well as in Computing undergraduate program. Due to the course comprehensiveness and recognised lack of interest, students tend to study without understanding the studied concepts and their practical application. This paper presents the proposal to increase the interest in electronics by introduction of the active learning (AL) process. This AL process is supported by the developed AL module, i.e. clicker, which provides the hands-on experience of the topics studied throughout the course. We provide questionnaire proposal that will be given to groups of students and the results will be compared to the control group to assess the usefulness of the proposed approach.","PeriodicalId":203046,"journal":{"name":"2017 40th International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO)","volume":"1 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":"129470255","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}

PSO is a method that optimizes a problem by iteratively trying to improve a candidate solution with regard to a given measure of quality to mathematical formula over the particle's position and velocity. The applied method explores the search space locally as well as globally and uses them in the mathematical formulas. The optimal design of IIR filter is realized with the result obtained with PSO.","PeriodicalId":203046,"journal":{"name":"2017 40th International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO)","volume":"142 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":"123416597","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 main challenge is how to address such a change with regard to the design of information systems and how those information systems are aligned with the change in human behaviour. This paper aims to address the issue of designing information systems that support Science 2.0 - a new phenomenon of interrelated sociotechnical interactions in which communication is the heart of science and the environment that enables critiquing, suggesting and sharing ideas and data in real time with almost no costs. This paper underlines problems related to the institutionalisation of knowledge transfer and its weaknesses. It also pinpoints John Dewey's primary and secondary experience as a point of departure which provides theories, theoretical frameworks and models such as information behaviour, documents and communities of action, the quadruple Helix model, activity theory, evolutionary learning and knowledge sharing communities. All these can be utilised for designing adaptive information systems that support better knowledge transfer.","PeriodicalId":203046,"journal":{"name":"2017 40th International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO)","volume":"4 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":"123739996","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}

Setting up such a network with a large number of physical interconnected IoT devices can be a challenge. In the IoT world, one of the key challenges is to efficiently support M2M communication in constrained networks. This can be achieved using MQTT (Message Queuing Telemetry Transport) and CoAP (Constrained Application Protocol) protocols. Choosing the appropriate protocol can be difficult while developing IoT application. There are several conditions that need to be considered while determining which protocol should be used. In this paper, we will evaluate performance and compare these protocols through different scenarios.","PeriodicalId":203046,"journal":{"name":"2017 40th International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO)","volume":"26 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":"121609816","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}

Two types of samples were studied: 1) tablets pressed at 1.5 GPa to form bulk samples and 2) thin films prepared from 35% ethanol-water colloidal dispersions by their filtration onto membrane filters (pore diameter is 20 nm). The electrical resistances of the samples were shown to be increased in the presence of ethanol and acetone gases at room temperature, thereby revealing positive response to reducing gases.","PeriodicalId":203046,"journal":{"name":"2017 40th International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO)","volume":"7 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":"124189875","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 converter operates close to the megahertz range. A specialized simulation model of the considered two-phase buck converter is proposed. The model allows an evaluation of current and voltage ripples at various duty cycles and inductor coupling factors. It can facilitate the design and tuning of such DC-DC converters. The model is implemented into a general-purpose simulation environment. The simulation results are presented and analyzed. The model is verified trough a dedicated experiment on a realized converter. Although coupled inductors increase the power converter efficiency, for high-current buck converter this effect is substantial at duty cycle bigger than 40 %. The advantages at lower duty cycle are related to the output voltage ripple and feedback response time. Design considerations are derived based on the analyzed simulation and experimental results of the investigated two-phase buck converter.","PeriodicalId":203046,"journal":{"name":"2017 40th International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO)","volume":"2 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":"125514609","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 effect of the phase noise on the constellation diagram for both M-QAMs is examined. The impact of changing the power of the input signal, phase noise and frequency offset on Bit Error Rate (BER) performance of 64-QAM and 256-QAM is also studied.
