This paper considers techniques of object-oriented analysis and design as a new tool for solving and analyzing convex polygon triangulation. The triangulation is analyzed from three aspects: forward, reverse and round-trip engineering. We give a suggestion for improving the obtained software solution of the polygon triangulation algorithm using technique that combines UML modeling and Java programming.

Enumeration, Ranking and Generation of Binary Trees Based on Level-Order Traversal Using Catalan Cipher Vectors
Vol. 3 No. 2 (2013): JITA – APEIRON Adrijan Božinovski, Biljana Stojčevska, Veno Pačovski Enumeration, Ranking and Generation of Binary Trees Based on Level-Order Traversal Using Catalan Cipher Vectors Original scientific paper DOI: https://doi.org/10.7251/JIT1302078B Abstract Download Article PDF In this paper, a new representation of a binary tree is introduced, called the Catalan Cipher Vector, which is a vector of elements with certain properties. It can be ranked using a special form of the Catalan Triangle designed for this purpose. It is shown that the vector coincides with the level-order traversal of the binary tree and how it can be used to generate a binary tree from it. Streamlined algorithms for directly obtaining the rank from a binary tree and vice versa, using the Catalan Cipher Vector during the processes, are given. The algorithms are analyzed for time and space complexity and shown to be linear for both.The Catalan Cipher Vector enables a straightforward determination of the position and linking for every node of the binary tree, since it contains information for both every node’s ancestor and the direction of linking from the ancestor to that node. Thus, it is especially well suited for binary tree generation. Using another structure, called a canonical state-space tableau, the relationship between the Catalan Cipher Vector and the level-order traversal of the binary tree is explained. Keywords: Enumeration, Rank, Generation, Binary tree, Level-order traversal, Catalan Cipher Vector, Canonical State-Space Tableau.

Comparative Analysis of Data Mining Techniques Applied to Wireless Sensor Network Data for Fire Detection – [Cloned #2413]
Vol. 3 No. 2 (2013): JITA – APEIRON Mirjana Maksimović, Vladimir Vujović Comparative Analysis of Data Mining Techniques Applied to Wireless Sensor Network Data for Fire Detection Original scientific paper DOI: https://doi.org/10.7251/JIT1302065M Download Article PDF Abstract Wireless sensor networks (WSN) are a rapidly growing area for research and commercial development with very wide range of applications. Using WSNs many critical events like fire can be detected earlier to prevent loosing human lives and heavy structural damages. Integration of soft computing techniques on sensor nodes, like fuzzy logic, neural networks and data mining, can significantly lead to improvements of critical events detection possibility. Using data mining techniques in process of patterns discovery in large data sets it’s not often so easy. A several algorithms must be applied to application before a suitable algorithm for selected data types can be found. Therefore, the selection of a correct data mining algorithm depends on not only the goal of an application, but also on the compatibility of the data set. This paper focuses on comparative analysis of various data mining techniques and algorithms and in that purpose three different experiments on WSN fire detection data are proposed and performed. The primary goal was to see which of them has the best classification accuracy of fuzzy logic generated data and is the most appropriate for a particular application of fire detection.

The Application of Information and Communication Technologies in Dance Sport in Bosnia and Herzegovina
Vol. 4 No. 1 (2014): JITA – APEIRON Velibor Srdić, Milan Nešićć The Application of Information and Communication Technologies in Dance Sport in Bosnia and Herzegovina Original scientific paper DOI: https://doi.org/10.7251/JIT1401023S Download Article PDF Abstract The research was performed with the aim of determining the frequency and ways of application of information and communication technologies (ICT) in dance sport in Bosnia and Herzegovina. The research was conducted on the sample of 33 dance clubs, that is, their representatives, with the condition for the clubs to belong to one of the two national dance associations of Bosnia and Herzegovina. The data were collected via interviews, associations’ web pages and their archives. The research utilized analysis and induction method. The results showed weak application of ITC in everyday work of dance clubs, but they also indicated the appropriate usage of ICT by dance associations (as the “umbrella” organizations of dance sport) at dance competitions. In this sense, it is advisable to steer finances towards improvement of dance clubs’ equipment and IT training of employees.

Influence of Resolution and Frame Rate on the Linear In-Stream Video Ad QoE
Vol. 4 No. 1 (2014): JITA – APEIRON Miloš Ljubojević, Vojkan Vasković, Zdenka Babić, Dušan Starčević Influence of Resolution and Frame Rate on the Linear In-Stream Video Ad QoE Original scientific paper DOI: https://doi.org/10.7251/JIT1401015LJ Download Article PDF Abstract An increasing number of services and facilities that are of interest to users is based on video streaming. Technical characteristics of video have a strong impact on the quality of a video streaming service and its perception by users. The most important measure of quality, which focuses on the user, is the Quality of Experience (QoE). Given that video advertising is a typical video streaming application, it is necessary to analyze the effect of the change of video characteristics on the QoE. This paper examines the impact of resolution and frame rate change on the QoE level by using objective and subjective QoE metrics. It also looks at the possibility of mapping the objective QoE metrics into subjective ones, if the QoE in Internet video advertising is analyzed. It was demonstrated that the values obtained by the objective assessment of quality can be mapped to the results obtained by subjective assessment of quality when the quality of experience of linear in- stream video ads is analyzed. The results indicate that temporal aspects of video quality assessment, e.g. influence of resolution and frame rate change to the level of the QoE, can be achieved by implementation of objective methods. Therefore, quality of experience can be improved by the proper selection of video characteristics values.

Selection of Telecommunication Access Networks
Vol. 4 No. 1 (2014): JITA – APEIRON Predrag Katanić Selection of Telecommunication Access Networks Original scientific paper DOI: https://doi.org/10.7251/JIT1401005K Download Article PDF Abstract The development of Internet technology and computer networks leads to the convergence of traditional systems voice, video and data into a unique IP-based TriplePlay system. Differences in implementing TriplePlay service basically come down to the choice of technology of data transmission from the last aggregation point (node) to a subscriber (Last Mile).Analyzing Internet market, the Organization for Economic Co-operation and Development (OECD) made trend in increasing demand for bandwidth during the period from 2007 to 2017. The analysis is based on SmartHome concept which includes broadband internet as well as multimedia services such as IPTV, cell phones and so on. The results of the analysis to a great extent confirm increasing trend of the consumers’ demand for bandwidth defined by Jakob Nielsen. His theory is based on the previous period and predicts that the need for bandwidth will rise by 50% every year. Nielsen’s diagram resembles that of Moore which predicts that CPU power will double every 18 months, that is 67% a year.The constant alterations in market and technology causes dilemma to operators in terms of investment. It is quite difficult to answer the question about the choice of technology of connecting the subscribers from the aspect of both technological and economic justification. Finding the answer to this question is the main goal of this paper. Keywords: Internet technology, Triple Play, VoIP, IPTV.
