SLAmeter - The evaluator of network traffic parameters

This paper introduces the SLAmeter network metering tool, which constitutes an alternative solution to the network traffic monitoring tools based on the IPFIX protocol. The main purpose of the SLAmeter is to offer a reliable possibility to track and fulfill the conditions specified in the Service Level Agreement subscribed between the subscriber and provider. SLAmeter was designed with the extension of the BasicMeter tool and consists of several components on different layers.

Innovative learning stories for teachers based on latest IT technologies

This paper deals with new ways of teaching and learning with major support of new technologies and software solutions in primary and secondary schools. Children are keen to use new technology, mobile devices, and internet applications. They use it more for out of school activities. School has to explore the potential of new technologies and offer curricula in attractive way. Connection between traditional and on-line content should be found, linking existing educational objects into IP world is necessary. Teachers are facing new challenges how to teach in a new setting different generation of pupils. This paper brings review of some tools and presents selected learning scenarios which should help to do so. Paper also presents project iTEC funded by European Commission which helps to solve some of the problems that teachers are facing. The research project wants to identify trends for future classroom, recognize best practices and test them in 1000 classrooms throughout the Europe.

Interactive eBook as a supporting tool for education process

This paper is trying to rediscover the usage of eBooks today in the form of a textbook. It describes the concept of electronic textbook, which provides to the reader some interactivity with the goal of improving his study experience. This concept is based on the results of Technical University of Košice.

On the Extraction of Anthropometric Parameters by Visual and Non-visual Means

In this paper the system for collection of anthropometric data is presented, along with the novel techniques for extraction of such data. System is built on selected open-source platform having developed various plugins as a part of the project. Means for extraction follow two approaches: visual and non-visual. The first presumes the acquiring of data from static 2D image, the latter gets data through the direct measurement. Visual approach utilizes several principles following the image processing and related face recognition algorithms. Moreover known anthropometric relations are utilized to estimate other proportions. The output in the form of data of individual user may serve as for statistical comparison with other users. Further such data is to be used for correlation studies with several diseases and changes of overall health condition.

Kinect as a tool in estimation of selected human body dimensions

The aim of this paper the extraction of human body dimensions using the latest Microsoft Kinect device. Another focus is the analysis of various application of this device in specific branches of science and research and its application in estimation of dimensions. Brief analysis of the device itself is carried out as well. The principal output of this paper the software application that utilizes data from Microsoft Kinect sensor in order to estimate the height of human body as well as the length of its limbs. Further comparison between both generations of Kinect devices is carried out.

Booking solution for video conference planning

In this paper, the solution for interconnecting the videoconference systems into a single videoconference infrastructure is presented. Further its users will be able to make reservations through developed web application. The paper presents complex analysis of technologies related to videoconferencing. Several ways of implementation of the web application while connecting to a central system for videoconference management are outlined. Subsequently, following the proposal, a functional web solution that enables planning of bookings for registered users of the systems is developed and tested in the real environment.

The experience from implementation of National telepresence infrastructure in Slovakia to support research, development and technology transfer

Almost two hundred sites located mostly at Universities were equipped in 2015 with latest videoconferencing devices and connected to one national network. This was covered by national project named National telepresence infrastructure to support research, development and technology transfer (NTI). This paper presents technological challenges behind, integration of hardware and software solutions in multi-vendor environment, problems faced and results after one year of usage. All technical and organizational work was covered by Slovak Centre of Scientific and Technical Information in Bratislava. This project had to fight with more problems, not only of technological nature, but mostly with providing help to end users allowing them to see advantages in new way of collaboration and changing the way they think and work. Implementation has brought fully new custom web based services designed and created based on experience with academic institutions and feedback gathered after project launch.

Personal mobile meter for development of human body skeletal model

In this paper, the innovative approach to extraction of the real size of the human body is presented. The prototype device for such extraction process is designed, implemented and tested on larger sample of subjects. The principal goal is the proposal of a solution for creation of exact skeletal human body model. Model dimensions may be further used in numerous use-cases, such as 3D modelling, clothing industry or security. Both, hardware and software, is based on the open-source technologies. The core functionality is enabled by developed hardware module that carries out the measurements of the real scene dimensions. Extracted values may be stored on the device itself or send to another mobile device. The accuracy of the solution proved to be 100 percent in terms of measurement in centimeters.

Secured web oriented videoconferencing system for educational purposes using WebRTC technology

This work deals with the means of videoconferencing systems ran by web browsers. It analyzes certain contemporary videoconferencing solutions and technologies used for multimedia streaming. It also describes the WebRTC technology terminology and presents the reader with its benefits. It sketches certain options for security enhancements for visual stream transmission via computer network. Based on the proposed concept it was possible to create an experimental web oriented videoconferencing system with a dual layer security policy in which students and teachers are able to communicate via chat and share files with each other besides audio and video communication.

First outcomes of designing the future classroom

This is the second paper presenting the iTEC project, we have first introduced at the ICETA 2011 International conference. The research is based on 5 cycles of testing learning stories and activities while using new innovative technologies in classrooms. Meanwhile the project has come to its middle point; the 3rd cycle of testing learning stories and activities is implemented in hundreds of classrooms of 17 countries this school year. The article discusses first international results from cycle 1, brings outcomes from cycle 2 on national level and presents new approaches coming with cycle 3. The project is focusing both on innovative pedagogies as on innovative technologies used in education. The iTEC project is funded by the European Commission.
