An emergent research topic is thus “Are science teachers succeeding in transferring to their students the digital competences specific to the study of science?” In the initial research phase, our intention was to prepare a Digital Competence Framework for Science Learning for Elementary school Students, and a proposal for how this could be applied in the science classroom. We began from a study of the Slovenian syllabus for Computer Science and Multimedia in elementary school. We discovered that, in science education, we cannot rely on students' digital competence even at the basic level (use of e-mail, internet browsers, word processors and home multimedia), a situation that calls for intervention by science teachers. Additionally, the school subject Computer Science and Multimedia is elective, which is another reason that we cannot expect students to be digitally competent in all classrooms, nor we can expect this kind of digital competency merely on account of the abundance of digital technology all around us. A framework was prepared and adapted for the basic, general and subject specific levels. Specific classroom situations are identified for clarifying the concepts, and classroom practices based on tested sources are proposed for presentation at the conference.","PeriodicalId":431110,"journal":{"name":"2018 41st International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO)","volume":"31 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":"114791086","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 analysis involved 186 students from 10 different institutions worldwide. The descriptive statistics is used to identify and explain the correlations between main constructs, as well as to explain the correlations between indicators that are direct benefits of using ePortfolios. The results confirmed the previous research implications and found the modest correlation between the Use and Net Benefits, as well as a moderate correlation between the User Satisfaction and Net Benefits.","PeriodicalId":431110,"journal":{"name":"2018 41st International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO)","volume":"38 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":"114860609","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}

Fonseca-Pinto","doi":"10.23919/MIPRO.2018.8400033","DOIUrl":"https://doi.org/10.23919/MIPRO.2018.8400033","url":null,"abstract":"Firstly described by Newton in the 17th century, speckle is an optical phenomenon which can be translated into image patterns produced by wave interferences of diffused reflections. In fact, the speckle pattern is generated by the multiple interference phenomena that occur when a rough surface is illuminated with a coherent source of light, producing randomly distributed reflected waves of the same frequency but different phases and amplitudes. Although it has been known for a long time, capturing video sequences of speckle patterns was dependent on recent technological developments, in particular, related to laser technology and microsensors. The speckle acquisition setup comprises a light source, usually a laser, an optical beam expander and a CCD camera. The generated interference patterns are captured in series of video sequences, to further be processed. In previous works, several image processing algorithms have been applied to analyze video frames of speckle, aimed to capture the evolution patterns in dynamic processes. However, due to the typical high frequencies of the changing patterns, classical texture algorithms mostly fail this goal. In this work, speckle dynamics are evaluated using Local Binary Patterns (LBP) jointly with some of its main variants and a newly proposed algorithm, in a reactive hyperemia controlled test. The proposed methodology goes beyond the traditional implementations of LBPs, by considering an additional Gaussian filtering, a methodology thus coined as LBPg. The results, on one hand, confirm that the classical formulations of LBP are not sensitive to changes in the simulated patterns but, on the other hand, demonstrate that the newly proposed LBP-adapted algorithm successfully identify the dynamics of the processes under study.","PeriodicalId":431110,"journal":{"name":"2018 41st International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO)","volume":"61 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":"131190289","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}

While the sequencing techniques are the biologist domain, the genome assembly is bioinformatical task and development of new assembly algorithms responds to the new sequencing methods. The final part of the assembly process is merging the contigs and find their position in the genome. Contigs are almost the final product but they can contain errors and features induced by previous assembly process. The current methods use string algorithms based on dynamic programming computing with characters (A, C, G, T) representing nucleotides, but if applied to long sequences, e.g. contigs, they tend to be time-consuming. We applied another approach based on genomic signal processing to evaluate the further merging and overlaps between the contigs. The genomic signal form of DNA sequence can reveal hidden features of sequences and digital signal processing methods can be applied. Also, the computational complexity of task can be reduced by implementing massive downsampling. We use our own implementation of cross-correlation based on Pearson correlation coefficient to detect possible overlaps between contigs, when high positive correlation indicates possible shared regions of the contigs but also to denote the position of that region, without the alignment.","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":"129735088","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}

On workplace they have to use technologies, which are used in practice of their employing enterprise, but often do not understand the scientific and/or technological principles on which these technologies are based. They seek explanations on Internet, but information on Internet is often low quality, one-sided and presented with business targets on mind — to get more users to technologies developed and sold by a business enterprise. Thus university has to explain basic principles of technologies what students already know and have used and correct some popular beliefs, which are supported by software vendors and based their business interests. Non-formal sources of knowledge — workplace training and Internet — do not reduce teacher's task, but force teachers constantly study all new which appears in this field, thus increase teachers workload. Students increasing use of non-formal sources of knowledge imply need for flipping the process — instead of teaching students are set to learn from provided detailed tutorials. Use of Internet and work has made self-study, seeking information from Internet sources very customary for current students, thus such flipping worked very well in a game programming course provided by the first author.","PeriodicalId":431110,"journal":{"name":"2018 41st International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO)","volume":"55 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":"129281298","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}

Three classes of power amplifier (PA) operation are investigated, namely Class A, Class AB and Class B. Matching impedances and bias points for all classes of operation are optimized by employing the load-pull and source-pull contours for output power and collector efficiency.

The FDDA was designed using the bulk-driven technique, and Rail-to-Rail (RtR) input voltage range was ensured through the use of bulk-driven input transistors. Additionally, the RtR input/output CMFB, based on FDDA topology, was proposed. The output voltage range is near RtR (±0.36 V). The CMRR and PSRR of 60.2 dB and 64.4 dB was achieved, respectively. The proposed FDDA shows very good linearity in wide output range, thus the THD of −156 dB@1 mV was reached. Furthermore, the proposed FDDA was used as a building block of an ultra-low voltage-to-frequency converter.","PeriodicalId":431110,"journal":{"name":"2018 41st International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO)","volume":"35 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":"134308409","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}

Improving the dynamics of off-line time synchronization in wireless sensor networks 改进无线传感器网络中离线时间同步的动态特性

Depolli","doi":"10.23919/MIPRO.2018.8400054","DOIUrl":"https://doi.org/10.23919/MIPRO.2018.8400054","url":null,"abstract":"The time synchronization in wireless sensor networks (WSN) is a well-known issue. One of the approaches to the problem is by using off-line algorithms, meaning that the exchange of signaling messages for synchronization of individual clocks does not take place. Such an approach is typically based on a linear regression, which serves as an estimate of the actual ratio of the clock rates in the network. Due to the ever changing conditions in the network, where the wireless channel reliability and clock rates vary over time, the method needs to adapt dynamically. In the process of adaptation, discontinuities of determined linear regression lines may appear, which causes sudden time offsets. In this article, new procedures are proposed to cope with the varying conditions in such a way as to achieve as seamless transitions as possible. It is shown that unless such procedures are used, time offsets in the order of up to half a second may appear as peaks observed in the transition from one state to another. The proposed method reduces the offsets by an order of magnitude. The effectiveness of proposed solution is demonstrated on a specific case of wireless sensor ECG measurements.","PeriodicalId":431110,"journal":{"name":"2018 41st International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO)","volume":"25 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":"132012884","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}
