Like fingerprints, each individual has unique patterns in the iris, which makes it a common approach for implementing visual biometric authentication. The paper describes a novel system for extracting the iris pattern and using it for identification of people. The system uses Haar wavelet decomposition and 2D Gabor filtering to extract the pattern data. The pattern data is then used with bitwise XOR comparison for final identification matching. Instead of manually selecting parameters for the Gabor filter, a machine learning method called Particle Swarm Optimization was used. The parameters that gave the best matching result were then implemented in the filter design. The implemented system was evaluated on images obtained from 6 individuals in different settings. The evaluation showed that matching identification could be achieved for the database used. The prepossessing of images with Independent Component Analysis was also used to remove the reflections on the images but that did not improve the classification significantly. Still we were able to perfectly distinguish between the individuals. Further preprocessing and a larger training database would be required to get more general and robust results.","PeriodicalId":437575,"journal":{"name":"2020 43rd International Convention on Information, Communication and Electronic Technology (MIPRO)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116746364","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 this purpose, Ge1-xSnx-alloys were grown on a relaxed Ge virtual substrate on top of a commercial Si (100) wafer using molecular beam epitaxy. The crystal structure and quality of the Ge1-xSnx-epilayers were analyzed by high-resolution X-ray diffraction. In order to extract the carrier mobilities in Ge1-xSnx, low temperature hall measurements were carried out, using a Van-der-Pauw-geometry. It is shown that with increasing Sn-concentration we find a decrease in carrier mobility, which corresponds to an increasing sheetresistance.","PeriodicalId":437575,"journal":{"name":"2020 43rd International Convention on Information, Communication and Electronic Technology (MIPRO)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116098546","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}

Advanced processes such as Selective Laser Sintering and PolyJet 3D printing are used. However, 3D printing of clothes still experiences some disadvantages, of which the biggest is the slow 3D printing speed and usually a small printing area of 3D printers. The novel, large multi-head printers can significantly increase the printing speed, but such printers require an additional step to prepare given 3D models that increase. However, pre-processing time grows exponentially with the number of printer heads, therefore computer resources that exceed the capabilities of a single workstation are required to prepare a printout. This implies the use of HPC resources, and because of its flexibility, lower cost and ease of use, HPC Cloud is optimal platform for such jobs. We have shown that the structure of these jobs fits perfectly in the HPC Cloud environment.","PeriodicalId":437575,"journal":{"name":"2020 43rd International Convention on Information, Communication and Electronic Technology (MIPRO)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116573199","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}

Although the communication process is embedded in all other common processes, few studies focus on the quality of communication, especially in education. Communication etiquette requires a greater number of communication skills due to the constant adaptation of situations in the environment. The survey was conducted on a sample of 257 teachers of primary education of the City of Zagreb and Zagreb County. The conducted research showed that primary education teachers show a noticeable higher level of communication etiquette (71.8%) than e.g. managers of social areas (43.21%). The reason can be found in two communication levels: the content and relation, whereby during initial education the relation level is often omitted without which there is no quality communication. It can be assumed that the student-professor relationship is more or less the same at all higher education institutions in Croatia, but that the social ones may differ from the technical ones regarding the content of courses which may contribute more to the development of communication culture.","PeriodicalId":437575,"journal":{"name":"2020 43rd International Convention on Information, Communication and Electronic Technology (MIPRO)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115642609","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}

We have used quantitative research methodology and as research method used a questionnaire to collect the data. We collected the data before and after playing the game, so we can assess the difference of the time spent on educational games and the level of transferred knowledge. The system is expected to help high school students to easily orient and engage during lecture classes and easily find and use the learning content. The system has been evaluated on its functionalities and the usability, on two groups of users, one group with computer science background and the second group of users as novices with different field background. Afterwards we used regression analyses to determine the impact. The research study tries to contribute with identified impacting factors for such systems, analyses of the improvement in user friendliness, and usability.

This paper analyses the possibilities, challenges and difficulties of automatic periodic collection and analysis of data from popular social networks and explains in detail the acquisition and analysis of data from Twitter. The paper explains an implementation of a simple hot topic detection algorithm based on texts acquired from the Twitter’s official API. The texts collected are being pre-processed by removing stop-words and stemming the remaining words using Porter’s stemming algorithm. Words from pre-processed text are assigned ranks depending on a large-scale analysis using TF-IDF weight and grouped into a hot topic. The algorithm accuracy was evaluated by comparison with Twitter’s official hot topic detection algorithm. Appropriate user interface enabling configuring the process of data acquisition, analysis and viewing results in a geographic fashion was implemented.","PeriodicalId":437575,"journal":{"name":"2020 43rd International Convention on Information, Communication and Electronic Technology (MIPRO)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121155704","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}
