Reordering Text Fragments Using a Language Model
Holubec, Michael ; Kocour, Martin (referee) ; Beneš, Karel (advisor)
The aim of this work is to construct and experimentally verify the effectiveness of the language model in identifying the reading order. For this purpose language model with LSTM architecture was constructed. This work designs and implements three methods which are used to identify reading order. These methods are Language analysis, Spatial analysis and Combined analysis. Language analysis and combined analysis used constructed language model. The success of the language model, and all three methods, was measured on three datasets containing newspaper articles. Language analysis reaches 57,6 % and spatial analysis reaches 91,6 %. Combined analysis achieved the best results 92,9 %. The work shows that the language model can be used to identify reading order but use of additional data (e.g. spatial data

Spatial analyses based on 3D city model
Florková, Miroslava ; Bartoněk, Dalibor (referee) ; Volařík, Tomáš (advisor)
The thesis is focused on geographic information systems and geographic data analyses tools. Examples of spatial analyses and tools for their creation are presented in ArcGIS at work. The main goal was to create a simulation camera system in the 3D urban model and to create spatial analyzes resulting in the camera's field of vision being intersected with the 3D model of the city. The result is 3D visualization, which shows the range of camera shooting areas. The results obtained were evaluated at the end.

Methodology for the solution of massive tasks in GIS
Opatřilová, Irena ; Hanzl, Vlastimil (referee) ; Cajthaml,, Jiří (referee) ; Řezník,, Tomáš (referee) ; Bartoněk, Dalibor (advisor)
This doctoral thesis deals with the issue of solving massive tasks in GIS. These tasks process large volumes of geographic data with different formats. The thesis describes a theoretical analysis of the complexity of tasks and the possibilities to optimize sub-processes which lead to an acceptable solution. It considers the possibility of using parallelism in GIS, which leads to an acceleration in the processing of large volumes of geographic data. It also proposes a method for the optimization of processes through an algorithm which determines the number of means necessary for the successful solution of a task at a specified time and assigns processes to these means. Additionally, there is a proposed algorithm for the optimization of the preparation of data for extensive GIS projects. The algorithms have been validated by the results of a research project, the aim of which was to analyse the terrain surface above a gas line in the Czech Republic. The primary method of analysis was the classification of an orthophoto image, which was further refined through filtration using the ZABAGED layers. Therefore, the thesis deals with the possibility of improving the results of image classification using GIS instruments as well as dealing with the determination of the error rate in analysis results. The results of the analysis are now used for the strategic planning of maintenance and the development of gas facilities in the Czech Republic. The results of the work have general importance regarding the performance of other operations of the same class in GIS.

GIS ANALYSIS IN BUILDING INFORMATION MODELS
Černý, Martin ; Kubíček,, Petr (referee) ; Vyhnálek,, Rudolf (referee) ; Bartoněk, Dalibor (referee) ; Pospíšil, Lubomil (advisor)
This dissertation thesis are concerned about the Geographic Information Systems (GIS) and spatial analyses inside of the Building Information Models (BIM). BIM and GIS are compared from different points of view like data organization, geometry types and modelling paradigms. Results of this comparisons are applied in the first case study where BIM data in IFC format are converted to the SHP format usable for spatial analyses in GIS. The results of the case study are evaluated and new approach for spatial analyses in BIM models is proposed based on the results. The new proposed approach is based on the semantic relations existing in the BIM models. Thesis are concluded with the future development which is in line with authors actual focus.

Analýza propustnosti krajiny pro zvěř na příkladu dvou pilotních oblastí v Rakousku
Jurečka, Mořic
The landscape of Central Europe is experiencing an increase in anthropogenic development and linear infrastructure. Landscape fragmentation has a number of negative environmental impacts. To mitigate the negative impacts, ecological corridors have been designed through GIS programmes. This paper focuses on the evaluation of the proposed ecological corridors and the analysis of potential impact factors in two pilot areas in Austria. Eighteen mammal species were recorded along the ecological corridors. The permeability of the areas in the pilot areas is problematic for large mammals. The work suggests that the degree of ecological stability and the presence of vegetation positively influence the number of mammal species on ecological corridors. Vegetation cover and other mitigation measures around the ecological corridors will be needed to ensure permanent permeability of the landscape.

The Impact of War-Related Violence on Post-Conflict Electoral Violence - A Disaggregated Analysis
Küsel, Evita ; Aslan, Emil (advisor) ; Kocmanová, Markéta (referee)
The international community frequently advocates elections in conflict-ridden societies as an integral part of peacekeeping strategies. However, elections themselves often become the focal point of contention and violence, potentially resulting in conflict recurrence. Given the severe consequences of electoral violence, scholars have increasingly focused on analysing its causes. While significant progress has been made in explaining the occurrence of electoral violence at the country level, these studies fail to account for the substantial intra-country variation of electoral violence. The present thesis fills this research gap by examining the spatial distribution of electoral violence within post-conflict countries. Specifically, the hypothesis proposes that areas within a country that have previously experienced war-related violence are more likely to witness electoral violence in the first post-conflict election. Through analysing spatially disaggregated data from the UCDP GED and ECAV datasets, this thesis conducts a country- fixed effects regression and finds a positive and statistically significant relationship between conflict-related violence and post-conflict electoral violence at the level below the state.
