Performance of such large heterogenous telepresence infrastructure can be limited not only by hardware resources utilization or network bandwidth but also with software cloud licensing limitations. After problem analysis we designed and implemented new NTI service booking system with ability to prevent high NTI resources usage. Research results are in form of integration of mechanisms of identification of critical nodes in specific booking time and mechanisms for proper technology resources balancing and effective license capacity distribution based on each service request. Proposed solution has been experimentally implemented in productive environment of NTI portal and it is currently used by research community resulting hundreds of conferences and live streams.

The key parameters we focus on are the total human body height, arm length, leg length, shoulders distance and head height. Prototype software solution utilizes Histogram of Oriented Gradients (HOG) and Haar classifiers algorithms. The analysis of existing object detection approaches in the image is carried out. Following this analysis, the suitable approach is selected, while bearing in mind the software prototype requirements. Further, the methods for extraction of human body parameters are presented and specific details of implementation are described. Prototype of the application enables specification of selected human body features having the output values close to the real dimensions of human body.

Republic of Moldova is one of European countries aspiring for a membership in European Union and its structures. The main goal of TEMPUS TecTNet project is to support the process by improving preparation of qualified experts working in the field of innovation and technology transfer at Moldovan universities and agencies. The paper presents the project, its main goals and achieved results in the fields of education and establishing infrastructure for cooperation among universities and industry in Republic of Moldova. The main focus is on developed master course, which is one of most important outcome of project.

Existing techniques are analyzed and also partially utilized in presented approach as an aid in the extraction process. The design of two different approaches was proposed, these were later implemented and tested. Proposed methods cover utilization of homography matrix, vanishing points and vanishing line. Developed system allows to determine the dimension of any object in image based on the value of reference dimension. Proposed software solution was tested in laboratory and real-world environment.

This year, the testing included two independent tests - one for the pupils of elementary schools and second for the respondents over 15 years. In our research we evaluated data from young people from 15 to 30, mainly students of secondary schools and universities who filled in the latter test. We tried to track down development of IT skills and knowledge during the secondary school study and to compare the results for particular school types and school grades.

NTI is effective collaborative environment with not only videoconferencing ability but it dispone also live broadcast functions, recording to multimedia archive or automatic conference booking system. Overall infrastructure consists of core layouts, web platform and over two hundred collaborative endpoints, which will be described in solution design. After one and half year of pilot operation the NTI shows trends of usage among research, development and innovation institutions. The paper shows also examples of real usage of live broadcasts ability of NTI.

The analysis covers information on the HBDF format and specific measurement procedures that are associated with the format and together form a coherent structure for the recording of such data. The structure of the format itself is implemented as XML schema, determining the content of XML outputs. Experimental software solution is designed and proves valid in the examination of HBDF structure. Schema ensures the data coherency and integrity, while the proposed solution ensures the import, operation, and export of data. The XML schema was experimentally tested as a part of multiple research projects.

Proposed innovations enhance the quality of education in IT, mathematics, science, and related technology areas that have as the main focus ICT. Further, they improve the motivation of pupils and students to study informatics and ICT, and help to develop scientific abilities of both, pupils, and students. Following the requirements of IT sector, in the 5 to 8 years the project aims to adjust educational system to educate 1000 new specialists, as compared to the current state. Project activities are designed for min. 24 000 pupils of primary school, min. 9 000 pupils of secondary schools, min. 3 000 students of universities and min. 1 800 teachers of primary and secondary schools from all over the Slovakia, except for Bratislava self-governing region. IT Academy as a sustainable system for education and training of specialists, recognizing the demands of IT industry, is based on market and IT sector requirements. It incorporates also the partnerships of all subjects within Slovakia that co-create the system itself — i.e. IT companies, universities, secondary school, primary school, self-government, and other subjects. Partnership with IT Academy is established in form of contract or memorandum of cooperation, giving the entity status of “IT Academy partner”.

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.
