Comparison of data on the total ascent along the recorded GPS tracks depending on the method of determining
Get PDFIn this thesis, we discuss data on the total ascent along 250 recorded GPS tracks, situated in western Slovenia. GPS tracks were recorded with a simple single-frequency code GPS recorder Qstarz BT-Q1000P with distance criteria of 10 m from the previously recorded point. From all recorded GPS tracks, we calculated the total ascent in different ways, namely directly from the recorded ellipsoidal heights, using different thresholds of height profile simplification, with the help of Google Earth in view mode of the recorded GPS track “Absolute” or “Clamped to ground”, meaning on the SRTM 90 m, and by laying the GPS tracks on DMV 1 m data from a recent recording of Slovenia with ALS, which we used as a reference. We evaluated the suitability of a particular method of determining the total ascent and empirically determined correction factors to ensure comparability of data with reference values and their mutual comparability. Based on the aggregated processing of 250 recorded GPS tracks, we found out that the total ascent, calculated from originally recorded, uncorrected GPS tracks, has to be reduced for 20 % on average, to get a value that is comparable to the reference. Total ascents, obtained with Google Earth in view mode “Clamped to ground” or calculated by the simplification threshold of 15 m, are on average too small due to more generalized terrain model or height profile, therefore it is necessary to increase them for 20 % on average to ensure the comparison with the reference values. It turns out that the sum of deviations, calculated by comparing each total ascent to its reference value, is on average the smallest when total ascent is determined using 5 m threshold of height profile simplification
Comparation of land use in the municipalities of Hoče-Slivnica and Kidričevo on municipal acts
Get PDFIn the thesis there was made an analysis of changing land use for the Municipality of Hoče - Slivnica and the Municipality Kidričevo. The municipalities are comparable to position and to size. The comparison was made for the area, in fact in the year 2004 and in 2013 or so to say in 2014. A description and development of the legislation was presented which defined the spatial acts of the Municipalities for the discussed examples. The range of land use as well as their presentation differs among the land use in the compared periods. Therefore a method was defined upon what a comparison can be made. The analysis was carried out on the software platform ArcMap 10.2. In the thesis there are presented comparisons of the surface area for basic and detailed land use by means of tables, maps and comments. Some examples of sectors are also charted. In either case the surface area of the building ground enlarged, but the surface area of farmland diminished
Calibration of a hydraulic model of the water supply system Šmartno ob Paki
Get PDFThe graduation thesis addresses the subject of calibration of computerized hydraulic model of the pipeline system Šmartno ob Paki. In this thesis I got acquainted with the characteristics of the pipeline system Šmartno ob Paki and software Aquis. With software Aquis I have done the calibration of water flow and pressure. Plumbing systems represent a dynamic system built from multiple components which interact. Computer programs help us to understand better static and dynamic properties of pipeline systems.\ud
Software Aquis was used as part of the thesis, with which measurements on the system were monitored and the model simulation was made. The scope of this thesis was to compare the results obtained by simulations and measurements and afterwards to calibrate the model by using the correction factor to increase the accuracy thereof
Energy renovation of selected building and proposals for improving the quality of indoor environment
Get PDFFor this thesis paper, I have undertaken the renovation of old buildings from 1932. The main problem which I have concentrated on is the dampness of walls and their repair. The aims were to preserve the original appearance of the buildings and improve living conditions inside them. Mould appeared in particular areas and using different measurements, I have tried to find its source. Using a lazar heat detector, I recorded the walls' surface temperature and how it oscillated at different points. At the same time, I also took measurements with a multi- unction detector, which consists of 4 functions in one aparatus. With this I recorded the relativity of moisture and the air temperature in the area. The collected data were put together with the air temperature readings and comparative moisture in the air, using the ARSO website, based on the TEDI calculation programme. With this programme, I have examined the corresponding constructional complex to see if from the selected data diffusion dampness is shown in any of the layers from the construction unit. Then when I had defined the problem, I began a constructional complex reconstruction in accordance with the PURES requirements, but from the point of view of the corresponding predicted heat factor U. Also assisting me were the technical building guidelines, the regulations concerning the efficient use of energy, the regulations governing the ventilation of buildings and air- conditioning, as well as the guidelines of directive EPBD-r.\ud
I propose a suitable solution plan and constructional complex, which have arisen from the measurements' data, virtual condition of the building and their corresponding arguments
Parameter sensitivity analysis of hydrological model Bolska
Get PDFConceptual hydrological model HBV is extensively used in operational hydrological forecasting and water balance studies. In this paper, we apply the HBV model on 190 km2 basin Bolska. Using the tools of Monte Carlo simulation, which is built in the HBV-light model, we analyzed the individual sensitivity of the parameters, a sensitivity by changing the two parameters and the influence of parameters on the maximum flow in the flood. Analysis were done on the basis of Nash-Sutcliffe model efficiency coefficient. Individual analysis showed greater sensitivity of response routine parameters with respect to other three routines; it is most clearly seen through the influence of the middle box outflow and lower box outflow on the total runoff. Parameters of the snow routine have proved to be insensitive. By varying two parameters simultaneously the sensitivity analysis revealed interdependence of parameters in most of parameter combinations, reflecting the uncertainty in the results. Parameters that showed the most\ud
influence on the maximum flow are: K0, K1, UZL, PERC and FC

The analysis of visual comfort in the high school Domžale
Get PDFIn this thesis the sphere of assuring visual comfort is discussed with the focus on how to best use daily or natural light. With the help of technical literature, standards and criteria in the theoretical part all the necessary demands to assure enough and modified lighting of spaces for different purposes are described. The empirical research focuses on the example of the high school Domžale, for which the measurements and simulations with the programming equipment DIALux 4.12.0.1 and VELUX Daylight Visualizer 2.6.7 are performed. The procedures of measurement and programming equipment for analysis of lighting of spaces are shown in detail. Further on different measures to improve visual comfort with the help of daily light for each analized space are sistematically presented. The results are shown in tables, graphs, pictures and descriptions, and are critically evaluated regarding the recommended values of minimal lighting of such spaces (300lx). The use of light shelves in the spaces of the first floor helps most in improving the situation, partially also white walls in all spaces aid in the improvement. Where this is possible – from the point of construction and design - there are additional window openings arranged. With the implementation of the roof windows in combination with appropriate shades it is possible to create almost ideal conditions of visual comfort in the attic. At the same time this sort of change does not hurt the existing architectural plan

Analysis of selected algorithms for generalization of digital elevation model with applications in selected fields of Geodesy and geoinformatics
Get PDFThe purpose of the thesis is an analysis of selected existing algorithms for DEM generalization through case application in selected fields of geodesy and geoinformatics like cartography, spatial analyses in GIS, and quality control. In its practical part, I used the test area of Semič, consisting of a plain and the Semič hill rising above. Via ArcGIS program, I conducted several simple surface analyses: calculation of slope, angle, curvature, and analytical hillshading using DEM 5, DEM 12.5\ud
and LIDAR data. By bilinear interpolation method, I resampled all three layers of spatial data from 12.5 resolution to 25m and 50m resolutions, and conducted analyses. I interpreted the analyses' results in the sense of three selected fields in geodesy and geoinformatics. LIDAR is the highest quality display regarding the level of detail. Especially in the flat part, DEM 12.5 and DEM 5 are more consistent, whereas DEM 5 and LIDAR tally better in the hilly tract. Analytical hillshading at 45° azimuth yields undefined surface displays, a reverse surface display at 135° azimuth, hills being valleys and valleys hills, while hillshading at a vertical 10° angle forms long shadows. The best contours are generated from LIDAR, where contours are generalized and reduced mainly in the flat tract. Resampling to better resolution from 12.5m to 1m, I searched for errors in the layers. Through indirect sampling, I obtained even more generalized displays compared to direct sampling. Exposition is least sensitive to generalization, while angle and curvature are much more so. In curvature, differences are well enough seen at 25m resolution, where we can also visually perceive the differences in concavity and convexity. The least differences are seen in plan curvature. When resampling to smaller resolution of 25m and 50m, the quality of display and DEM data decreases, but I obtained more equivalent inter-layer displays at 50m resolution
Benchmarking of municipial waste collection service
Get PDFWaste management as well as certain other services provided in the public interest and in society generally special status. Utilities, among which also includes services in the field of waste management, both by their nature, monopolistic activities. Since it is an activity in which the absence of a monopoly lead to increased costs and, consequently, higher benefits for citizens, the system should aim that it is carried out as effectively as possible.\ud
The tool of benchmarking is generally accepted tool for the comparison of complex systems. It is used in many systems, but in the field of waste management is actually still very limited and has not developed. The reasons for this are that the only area developing rapidly, we are in a world witnessing rapid changes in the development, use of materials, use of resources, behavior and responsiveness users ... Nevertheless, comparisons are beginning in some other utilities are comparisons already more Developed and also a benchmark with other public services already exist.\ud
The company Snaga collects waste in the area of the Municipality of Ljubljana (MOL) and the suburban municipalities Brezovica, Dobrova - Polhov Gradec, Dol pri Ljubljani, Horjul, Medvode, Škofljica and Velike Lašče on the basis of a combination of deposition system and door-to-door waste collection. In 2012 we introduced a simpler, more user-friendly method of collecting packaging which increased the collected quantities - we’ve distributed bins and containers for packaging. Using bins outside their buildings, residents collect residual, biological waste and packaging and paper (on demand, in MOL). At the same time Snaga reduced frequencies of removal of residual waste and thus motivate citizens to increase the separation of waste at origin.\ud
At the same time we want to increase the efficiency of collection of municipal waste to achieve at least comparable values of efficiency indicators in comparison with other similar companies in branch, which has largely succeeded
