The main requirements include portability, low hardware requirements, and accuracy. The paper includes analysis of the algorithms employed for image processing, human detection and methods for estimating height of human. The experimental software solution is implemented in Python programming language. The SSD algorithm was selected to detect the person in the image and the output was later on utilized to calculate the real human height. A calibration object in a form of ArUco marker and its known dimensions became the foundation for calculating the real human height. The experimental testing confirmed the accuracy of the developed solution to be sufficient for the real-world application. The most accurate height, with just a deviation of 0.001 meters, was estimated at a distance of 5 and 8 meters. The approach presented in this paper is also to be used as a complement by newly proposed unmanned aerial vehicle security system.","PeriodicalId":194572,"journal":{"name":"2021 19th International Conference on Emerging eLearning Technologies and Applications (ICETA)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123546639","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}

What is more, there are not only people. There are devices connected to networks and communicating together, which opens many new possibilities in each area of everyday life, also known as Industry 4.0. Machines and people produce a lot of data, also called Big Data. By collecting and analyzing metadata about mobile communications, it is possible to improve different services provided by telecommunication companies or improve infrastructure itself. Some existing solutions are described in our work. We tried to combine two approaches, visualization of data and statistical analysis and based on that, we have proposed, implemented, and tested a new tool, which can help data analysts in the future.","PeriodicalId":194572,"journal":{"name":"2021 19th International Conference on Emerging eLearning Technologies and Applications (ICETA)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125414067","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}

Descriptive statistics were applied to data collected by a questionnaire from 1146 teachers and students from Estonia, Italy, and Serbia. In this research, we investigated the impact of COVID-19 on teaching and learning methods and the main challenges in digital teaching and learning. The empirical results showed that most higher education institutions implemented different digital platforms and switched entirely to online or blended learning. In addition, a sense of belonging through distance learning and delivery of “practical” lectures were found to be the key issues for the successful implementation of teaching and learning during the pandemic. Proper training of teachers, utilization of engagement tools, and investments in virtual laboratories could be a solution to the successful implementation of digital education.","PeriodicalId":194572,"journal":{"name":"2021 19th International Conference on Emerging eLearning Technologies and Applications (ICETA)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126971880","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 objective of the contribution is to identify the specifications of the basic training course for air traffic controllers. Since it is a professional and practically demanding training, the requirements for obtaining a License are also demanding.

A number of alternative approaches to mobile computing access have emerged during the last two decades. Given the diverse nature of the mobile domain in its entirety, it is obvious that no single technique will be suitable in all circumstances. In the field of architecture solutions, the prominent approach is service oriented. Indeed mobile environments are intrinsically asynchronous, distributed and based on services where one component can supply to whichever other entity on the web can be interested into. We propose a system based on mobile devices and distributed. The web-based architecture allows to query, retrieve, correlate and display heterogeneous informative contents taken from legacy enterprise applications. The enterprise application receives rough data from physical sensors geographically spread around. Design solution will cover only the client application running on the user’s mobile device and the application business logic level, while no consideration will be made about enterprise application architectures, types of DBMS used and types and configuration of physical devices. The most appropriate architectural models in this context are: distributed, agent-based, service-oriented, component-based.","PeriodicalId":194572,"journal":{"name":"2021 19th International Conference on Emerging eLearning Technologies and Applications (ICETA)","volume":"448 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115613539","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}

In this work, we report on experimental measurements and theoretical analysis characterization for PMD-based propagation effects in optical fibers influenced by wind gusts.
