ICIST 2014 Proceedings Vol.2, 333-337
Kranjac Mirjana, Sikimić Uroš, Dupljanin Đorđije, Dumnić Slaviša
Abstract: Public administration has to be leader into establishing of information society. The reason for it is its important role in raising awareness of necessity to implement information telecommunication technologies (ICT) into the all areas of social activities. Secretary for economy of the Government of Vojvodina supports activities of old handicrafts by giving financial donations to them through competitions. Such support has proved to be good but it has not improved visibility of old handicrafts. It appeared that public administration could add value to old handicrafts work through additional service. Additional service is old handicrafts promotion. For the promotion were used multimedia ICT tools. The paper presents activities of elaboration of interactive map of old handicrafts performed at Secretary for economy of Government of Vojvodina. Interactive map includes handicrafts description and photos and offers personalized touristic routs that enables visits to old handicrafts sites and practicing of traditional crafts.

Bobar Vjekoslav, Mandić Ksenija
Abstract: Public e-procurement is recognized to be the main area of government-to-business that needs to be exploited by government of developing nations. In this paper we give all details about public e-procurement in Serbia with a view to offering an improved approach. Here are described the main transformation phases from traditional form of public procurement to electronic form and each phase is described. Using three-tier architecture in software engineering a new logical model for the public eprocurement system in Serbia was designed and developed to eliminate the bottlenecks with existing systems. The certain parts of the use cases, class diagrams, decomposition levels and sequence diagrams in development of public eprocurement system in Serbia are given. At the end, we pointed out possibilities for further development in the field of public e-procurement systems, mostly concerning development in cloud environment.

232. Using Syntax Diagrams for Teaching Programming Language Grammar

ICIST 2014 Proceedings Vol.2, 363-365
Suvajdžin Rakić Zorica, Popov Srdjan, Petrić Tara
Abstract: Understanding the syntax is an important activity in the process of learning the new programming language. One of the main factors, which influence acceptability and clarity of the syntax, is the way in which the syntax is described. There is no consensus about which metalanguage is best for describing the syntax. The traditional way of learning syntax involves using Backus-Naur form (BNF), which is a bit confusing and not very popular among the students. Using syntax diagrams and tools for syntax visualization is better way for understanding and learning grammar of the programming language.

Stufi Martin, Veljković Nataša, Bogdanović-Dinić Sanja, Stoimenov Leonid
Abstract: As part of the Smart Administration strategy of the Czech Republic, Czech government has adopted a unique solution to centralize and to keep actual, most common and widely used information. The basic registers are the central information source for information systems of public authorities in the Czech Republic. Along with the Czech Point as the interface to all administrative requests and Data box as the electronic mail box the three projects represent a cornerstone of the effective public administration in the Czech Republic. This paper describes the current status of Public Administration (PA) in the Czech Republic and gives the characteristics of the optimal PA Information System (PAIS) and guidelines for its possible implementation in the Republic of Serbia.

ICIST 2014 Proceedings Vol.2, 376-381
Nikolić Vojkan, Protić Jelica, Đikanović Predrag
Abstract: European Commission recognized interoperability as a key factor in development of national eGovernment in the member states of European Union (EU) and as the unique eGovernment at the level of EU. The European Interoperability Strategy (EIS) and the European Interoperability Framework (EIF) which are used for European public services represent two key elements in the Digital Agenda for Europe promoting together interoperability among public administrations. Since National Interoperability Framework (NIF) of the Republic of Serbia was adopted on January, 10th 2014, until then the development of eGovernment in the Republic of Serbia had been in accordance with EIF where EIF had been the only document and guideline relating to eGovernment interoperability in the Republic of Serbia. This study shows eGovernement interoperability in the context of EIF and the proposed solution of connecting portal of eGovernement and Ministry of Interior Affairs (MOI) Republic of Serbia through Enterprise services bus (ESB).

236. Integrating processing in RAM memory and its application to high speed FFT computation

ICIST 2014 Proceedings Vol.2, 382-387
Efnusheva Danijela, Tentov Aristotel
Abstract: The growing rate of microprocessor performances significantly overcomes the one in DRAM memory. This problem of ever-increasing gap between CPU and memory speeds has been explored by many researchers. As a result, diverse specialized memory chips, that integrate processing, have been proposed. This paper discusses the architecture and implementation of several "smart" memories (computational RAM - CRAM, processing in memory - PIM chip and intelligent RAM - IRAM), including their strengths, weaknesses, and opportunities for high speed processing. Considering that these integrated chips allow for a high on-chip memory bandwidth and low latency, we examine IRAM's application for performing memory intensive operations, such as the complex calculations of the fast Fourier transform (FFT).

Dimčić Tomislav, Drajić Dejan, Krčo Srđan
Abstract: In this paper a few implementations were presented in order to show the importance of the IPv6 usage for IoT and possibilities that IPv6 offer. It is done in order to overcome addressing and routing limitations of IPv4 based mobile networks and WiFi. Two set-ups are presented. In the first one, smartphone is used as end point that could be accessed directly through the IPv6 address. Second set-up shows how smartphone could be used as a half-gateway for non IP devices, and provides access to the devices that use Bluetooth or Infrared communication with smartphone.

239. Analysis of Monitoring Dipole and Monopole Antennas Influence on Shielding Effectiveness of Enclosure with Apertures

ICIST 2014 Proceedings Vol.2, 399-404
Milutinović Vesna, Cvetković Tatjana, Dončov Nebojša, Milovanović Bratislav
Abstract: In this paper, numerical model of metal enclosure with apertures and monitoring antenna is considered for the purpose of accurate shielding effectiveness calculation. TLM method incorporating wire node model is used to account for the presence of monitoring dipole or monopole antennas used in practice to detect the level of electromagnetic field at selected points inside the enclosure. Numerical model is first verified through comparison with experimental results and then used to study an impact of physical parameters of considered antennas on shielding properties of rectangular enclosure and shift of its resonance frequencies. In addition, both antennas are mutually compared in terms of their influence on detected level of electromagnetic field inside enclosure.
