Each phase of realization consists of numerous procedures in order to obtain ultra stable, high quality devices competitive on international markets. Quartz crystal unit is the heart of almost all devices for frequency control. Our proposal is to realize high-stability OCXO SC cut crystal unit from 5-30MHz band, with strict demands from the list of technical characteristics especially having in mind low phase noise, short-term and long-term stabilities. It is further planned to develop and realize ultra-thin micro-miniature AT cut crystal units for frequencies from 30-180MHz intended for filters with special demands for position and suppression of spurious resonanties, intermodulation, environmental characteristics and small frequency deviation in wide range of temperatures.
Viminacium, roman city and military legion camp – research of material and non-material of inhabitants by using the modern technologies of remote detection, geophysics, GIS, digitalisation and 3D visualisation
Project duration: 2011-2014
Project code: III 47018
Project coordinator: Institute of Archeology
Participants from Singidunum University: Milan Milosavljević
Abstract
Subject of research are the remains of the Roman city and military camp Viminacium, which is situated in the counties of the villages Stari Kostolac and Drmno. The importance of Viminacium is that it represents the only Roman city and military camp which is not endangered by modern agglomerations. During Roman times, it had more than 35.000 inhabitants. Viminacium was the capital of the Roman province Moesia Superior, the administrative, economic and cultural centre for the area on the northern border of the Roman Empire. Within the area of the archaeological site Viminacium, during the past several years, multidisciplinary systematical geo-physical research is taking place before archaeological excavations. The application of geo-physical methods includes common work of geo-physicists, electro-engineers and archaeologists. Decisions about convenience of an archaeological site for applications of such methods, its stratigraphy, geo-physical contrast, the overview of archaeological documentation, as well as the project of measuring itself must be a result of common work. It is clear that, for a competent interpretation of geo-physical data, one needs multidisciplinary activity. After geo-physical and archaeological research comes an anthropological analysis and after that an interpretation that explains the population of Viminacium and its material culture. At this moment, the only Roman amphitheatre at the territory of the former province of Upper Moesia is being excavated.
Research of technical-technological, staff and organizational capacity of Serbian Railways, from the viewpoint of current and future European Union requirements
Project duration: 2011-2014
Project code: 36012
Project coordinator: Faculty of Transport and Traffic Engineering, University of Belgrade
Participants from Singidunum University: Irina Branović
Abstract
The project will include the research of the current situation and the EU requirements related to the field of railway transport safety, with special emphasis on the way of formation and financing, organizational and staffing structure, scope and working methods of so called “Safety Authority”, an entity dealing with the investigation and analysis of rail accidents, as well as proposing measures to raise the level of security. The aim of this part of the research is to propose optimal solution for “Safety Authority” in the Republic of Serbia. Special attention will be devoted to the research related to the potential of Serbian Railways in terms of EU requirements related to the compatibility and interoperability of technical systems, both in the field of technical exploitation characteristics and maintenance. Traffic-technical and organizational requirements that will appear in our railways upon Serbian EU entry, especially on Corridor X, will also be analyzed. Measures to meet these requirements will be proposed. Requirements for intermodal transport will be given special attention. In this regard, the EU environmental requirements regarding rail transport will be analyzed and possibilities of fulfilling the requirements by Serbian Railways will be explored. The situation regarding normative regulation of railway traffic will be explored and activities with the aim of raising this area to the required EU level will be proposed.
Development and Application of Methodes and Laboratory Equipment Intended for Conformity Assessment of Technical Products
Project duration: 2011-2014
Project code: 35031
Project coordinator: Institute of Nuclear Sciences Vinča
Participants from Singidunum University: Predrag Popović
Abstract
Adjusting of technical legislation of the Republic of Serbia with the European legal heritage is of high importance for the economy, as it creates preconditions for increasing exports and provides consumer protection from non-quality products at the local market. Successful application of harmonized technical legislation requires upgrading of the infrastructure required for conformity assessment in the Republic of Serbia which will be in the position to apply the conformity assessment methods that are in accordance with the essential requirements of the compulsory EU Directives. In that way, producers would acquire the right to use the “CE“ labeling for their products, which is the proof of the product being safe for people and environment, and which confirms to the government organizations that the product has had a legal placement on the market. Due to the significance of these activities for the national economy development and for consumer protection, the authorized Conformity Assessment Bodies have to be empowered in compliance with the criteria set out in relevant directives and international standards regulating their field of work. The strengthened products conformity assessment infrastructure would become a technical service where producers wishing to market their products on the EU market could get all necessary technical information and certificates on conformity of their products with the requirements of relevant Directives, as well as to get actual assistance in analyzing and assessing the risks related to usage of the products. The expected project results would considerably help development of the products conformity assessment methods and proceedings, in accordance with the EU harmonized technical regulations, especially regarding the products where technical safety is relevant. This is a precondition for the economy of Serbia to create, in the priority fields, the products of necessary quality that can be competitive in the international market.

Abstract
The importance of research within this project stems directly from the significance of meeting the economic dimension of competitiveness of the country, i.e., equal participation of Serbia in the European and global market of goods and services. Thus, it is obvious that the companies (the focus of this project is a company) can and must activate all internal technical, technological, human, financial and other resources in order to achieve the required level of competitiveness of goods and services offered in the domestic and foreign markets. It should be emphasized that competitiveness in the domestic market is often underestimated and neglected despite the fact that it is extremely important as it represents the first step on the path towards achieving competitiveness in the European and global market. Competition in the domestic market is occasionally sharper and more complex for some goods and services, primarily due to the effects of some non-economic factors that are, in most cases, political provenances.

Abstract
The characteristic polynomial of any square matrix of order can be computed in time by the standard algorithm. So, the same applies for computing the characteristic polyno0mial of graphs of order For some special classes of graphs, however, like threshoild and chaim graphs, the time complexity bound can be significantly improved by the exploiting their combinational structure. For example, for threshold graphs the bound is recently decreased to. Here we put forward some novel ideas based on the divisor technique to obtain another fast algorithm for computing the characteristic polynomial of threshold and chain graphs, as well as some other graph classes.
