Analysis of accuracy and precision of GNSS zenith tropospheric delay
Get PDFThe aim of the thesis was to compare the calculations of zenith tropospheric delay, computed within the meteorological model, with an independently acquired calculation of three GNSS data processing methods. Data analysis was done in the absolute and relative mode of determination. Using absolute mode of zenith tropospheric delay computation we computed the differences between the computed zenith tropospheric delay with the meteorological model ALADIN, taken as a reference, and results of zenith tropospheric delay computation on the basis of GNSS observations processing with geodetic methods (PPP, Bernese GNSS Software, network SIGNAL). The absolute zenith tropospheric delays values of chosen reference station we used for calculation of the relative tropospheric delay. Thus obtained values of differential zenith tropospheric delay we compared with the values obtained from the meteorological model. On the basis of calculated differences the mean value of the differential tropospheric delay and the standard deviations were calculated. These data were then evaluated. The obtained values of zenith tropospheric refraction show a high level of conformity between values obtained on the basis of GNSS data processing with the meteorological model, particularly in the relative mode using with PPP method and Bernese GNSS Software

Systematic analysis of tenders and selection of subcontractors for facade works
Get PDFThe thesis topic deals with the selection of subcontractors from the perspective of main contractor company. It describes a model of systematic analysis of subcontracting bids and selection of subcontractors. It focuses on communication with subcontractors in the early stage of bidding the project. The paper presents the evaluation and selection of projects to be checked for suitability and further discussion and elaboration of the tender. Inquiring, receving and analysing of subcontractors bids\ud
is a topic that in the paper is detaily presented. These are also essential for effective communication with subcontractors. In more detailed ways the problems are explained that may occure in the analysis of subcontractors offers and inclusion of those in the main contractor's offer. Before the final selection of a subcontractor the one should also be evaluated as unreliable subcontractors may cause inconvenience. Through the thesis the process of selection of subcontractors for facade works is shown on an example
Earthquake-resitant design of house JUBHome
Get PDFIn the thesis a two story reinforced concrete building built according to the system JUBHome is designed. JUBHome is an energy efficient system, which composed of the following subassemblages: JUBHome BASE, JUBHome WALL, JUBHome FLOOR and JUBHome ROOF. The study presented in the thesis was limited to design of foundation sub-assemblage and the wall. The guidelines for design of such systems were developed at the Institute of Structural Engineering, Earthquake Engineering and Construction IT (FGG-IKPIR). The\ud
design is based on the target risk and the experimental investigations which performed at the Faculty of Civil and Geodetic engineering (FGG). In the first part of the thesis the guidelines for earthquake-resistant design of JUBHome buildings is presented. Follows the description of the investigated building and response spectrum analysis, which was performed by program SAP2000. The flexibility of thermal insulation under the foundation slab was modeled in approximate manner. It was proved that the conditions against the overturning and the sliding of the building are satisfied and that the stresses in the thermal insulation do\ud
not exceed the capacity. The selected wall was then designed in order to achieve adequate shear and flexural strength. The reinforcement plan for the designed wall is presented at the end of the thesis
Analysis of the consequences of the Vogršček dam failure
Get PDFThe safty of flooding is very important,because the consequences that appear by the destruction of the large dam are catastrophical and are seen even years after the\ud
destruction. In my thesis i have described the large dam called Vogrscek, which is also the biggest large dam in Slovenia. The large dam serves as watering of farmlands downstream. I have studied the possibilities of the destruction of the large dam and analyzed the conseqencess that could appear. I have come to the conclussion, that we can prevent the possibility of destruction with frequent technical checks to the point that it almost can't appear. The large dam that can be destroyed only in the case of an catastrophical earthquke, or in some other special cases, is still one of the most dangerous constructional objects in Slovenia. With a quick reaction and informing in the case of destruction , there can be saved a lot of lifes
The problem of placing the roma settlements in the case of municipality Grosuplje
Get PDFFrom the aspect of spatial planning, development, placing and planning of Roma settlements must be inventive. In this master's dissertation, inventiveness has been defined with the following approach: i made a field research of a designated population of Romas on sporadic areas, exmined their leve of socialisation and habits, with regard to the specifics of their culture. This, when used in accordance with principles of holistic spatial planning, enables us to better place new Roma settlements or develop and enlarge existing ones. Inclusion of Romas from the first stages of development and complying with the elements od spatial policies. Compliance with the hierarchy of the legislation, coordination between the state and the municipality, the inclusion of sectors, the inclusion of the public, adjusting the legislation with flexible spatial restrictions, emphasizing the cases of good practice and efficient sistemic actions are just some of the most important principles. All the procedures must be carried out with cooperation of four main players: the state, municiplity, Romas and the local population.\ud
The issue of Roma people is multi-layered, so it needs to be tackled with an interdisplinary approach. This aster's dissertation discusses a segment of spatial challenges, namely the research of a pilot model of placing new Roma settlements or develop and enlarge existing ones in the case of dolenje Romas. For the purpose of this master's dissertation, we focused on settlements with up to 120 inhabitants
Dissertations and data
Get PDFThe keynote provides an overview on the field of research data produced by PhD students, in the context of open science, open access to research results, e-Science and the handling of electronic theses and dissertations. The keynote includes recent empirical results and recommendations for good practice and further research. In particular, the paper is based on an assessment of 864 print and electronic dissertations in sciences, social sciences and humanities from the Universities of Lille (France) and Ljubljana (Slovenia), submitted between 1987 and 2015, and on a survey on data management with 270 scientists in social sciences and humanities of the University of Lille 3.\ud
The keynote starts with an introduction into data-driven science, data life cycle and data publishing. It then moves on to research data management by PhD students, their practice, their needs and their willingness to disseminate and share their data. After this qualitative analysis of information behaviour, we present the results of a quantitative assessment of research data produced and submitted with dissertations Special attention is paid to the size of the research data in appendices, to their presentation and link to the text, to their sources and typology, and to their potential for further research. The discussion puts the focus on legal aspects (database protection, intellectual property, privacy, third-party rights) and other barriers to data sharing, reuse and dissemination through open access.\ud
Another part adds insight into the potential handling of these data, in the framework of the French and Slovenian dissertation infrastructures. What could be done to valorise these data in a centralized system for electronic theses and dissertations (ETDs)? The topics are formats, metadata (including attribution of unique identifiers), submission/deposit, long-term preservation and dissemination. This part will also draw on experiences from other campuses and make use of results from surveys on data management at the Universities of Berlin and Lille.\ud
The conclusion provides some recommendations for the assistance and advice to PhD students in managing and depositing their research data, and also for further research.\ud
Our study will be helpful for academic libraries to develop assistance and advice for PhD students in managing their research data, in collaboration with the research structures and the graduate schools. Moreover, it should be helpful to prepare and select research data for long-term preservation, curate research data in open repositories and design data repositories.\ud
The French part of paper is part of an ongoing research project at the University of Lille 3 (France) in the field of digital humanities and research data, conducted with scientists and academic librarians. Its preliminary results have been presented at a conference on research data in February 2015 at Lille, at the 8th Conference on Grey Literature and Repositories at Prague in October 2015 and published in the Journal of Librarianship and Scholarly Communication. The Slovenian research results have not been published before.\u
Transformation of BIM model to building energy model (BEM)
Get PDFBuilding energy analyses in Slovenia are usually performed by tools that do not offer interoperability with building information modelling and other modelling software. This means that several geometrical models need to be re-created for the same building.\ud
A repetitive input of geometrical and non-geometrical data into different software packages is a time consuming, costly, and error prone process. Building information modelling (BIM) is replacing traditional two-dimensional drafting and BIM offers interoperability with different simulation tools. In this thesis we explore the energy analysis through the use of ArchiCAD with its plugin Ecodesigner STAR. This program offers seamless transformation from building information model to building energy model within the same software. Building energy analysis software, developed in Slovenia uses a quasi-stationary calculation method. ArchiCAD uses a more precise hourly method, but does not consider standards valid in Slovenia.\ud
We used simplified cases to test the software and to develop modelling guidelines. We also studied the possibility of using geometric and non-geometric data generated by ArchiCAD in third party software, that considers calculation methods valid in Slovenia.\ud
The transformation from building information model to building energy model is shown in the case of a block of flats. Step-by-step measures were taken to achieve better energy efficiency of the building. During the process strengths and weaknesses of the software were identified. We concluded that the software is most suitable for quick energy analyses in the design stage and as a decision support tool about reasonability of measures taken to improve building energy efficiency
Positional accuracy control of national orthophoto with GNSS positioning
Get PDFOrthophoto is very popular among the users, but its quality is not regulated, since there is no mandatory quality control standard existent in Slovenia. Quality check is performed systematically during the implementation of the project of the Cyclic Aerial Survey of Slovenia and with the support of the scientific and technical report (Kapnias et al., 2008). A number of standards are being used abroad to control the positional accuracy of spatial data, among which the most relevant are the National Standard for Spatial Data Accuracy (NSSDA) and the Standardization Agreement 2215 (STANAG 2215). Since both standards differ considerably in the size of the sample and the statistical model, they were put to test in the master thesis by using them to control the quality of the national orthophoto from the 2014 time series in the trigonometric district of Celje. The orthophoto and stereopair control points were measured and reference values were obtained by the GNSS RTK method. Data was processed by using the methodology of both standards and the standards were subsequently evaluated. Orthophoto was produced for two sections by using DMR 1 obtained from the laser scan data, and the reduction in variation at control points was examined. The results were interpreted and STANAG 2215 was suggested as the national standard for measuring the quality of positional accuracy of orthophoto in Slovenia
