Míry podobnosti pro nominální data v hierarchickém shlukování
Šulc, Zdeněk ; Řezanková, Hana (advisor) ; Šimůnek, Milan (referee) ; Žambochová, Marta (referee)
This dissertation thesis deals with similarity measures for nominal data in hierarchical clustering, which can cope with variables with more than two categories, and which aspire to replace the simple matching approach standardly used in this area. These similarity measures take into account additional characteristics of a dataset, such as frequency distribution of categories or number of categories of a given variable. The thesis recognizes three main aims. The first one is an examination and clustering performance evaluation of selected similarity measures for nominal data in hierarchical clustering of objects and variables. To achieve this goal, four experiments dealing both with the object and variable clustering were performed. They examine the clustering quality of the examined similarity measures for nominal data in comparison with the commonly used similarity measures using a binary transformation, and moreover, with several alternative methods for nominal data clustering. The comparison and evaluation are performed on real and generated datasets. Outputs of these experiments lead to knowledge, which similarity measures can generally be used, which ones perform well in a particular situation, and which ones are not recommended to use for an object or variable clustering. The second aim is to propose a theory-based similarity measure, evaluate its properties, and compare it with the other examined similarity measures. Based on this aim, two novel similarity measures, Variable Entropy and Variable Mutability are proposed; especially, the former one performs very well in datasets with a lower number of variables. The third aim of this thesis is to provide a convenient software implementation based on the examined similarity measures for nominal data, which covers the whole clustering process from a computation of a proximity matrix to evaluation of resulting clusters. This goal was also achieved by creating the nomclust package for the software R, which covers this issue, and which is freely available.

Investment Decision Making of State and Local Governments
Kula, David ; Fotr, Jiří (advisor) ; Ochrana, František (referee) ; Potluka, Oto (referee)
The topic of this dissertation thesis is collection, analysis and evaluation of information about investment decisions making within public administration bodies. The investment decision making is examined in relation to allocation of public funds on investment activities and projects. The main goal of this thesis is to analyze and evaluate the current status of the investment decision making within the public sector. Subsequently the goal is to offer new or updated knowledge related to these issues, and bring recommendations to improve the investment decision making of public administration bodies. At first, there are described current knowledge in the field of investment decision making. This is followed by an analysis of assessment methods used for evaluation and selection of investment projects. The work is completed by recommendations for investment decisions making in the form of a normative model. The model should increase benefits of public investment expenses for society. There are used data obtained through a questionnaire survey of 430 subsidized firms, 169 state organizational units and state funds and 130 cities, boroughs and counties. Another important source of information was secondary data of selected ministries and agencies, legislation and literature.

Building and use of smaller computer networks
Kyzivát, Marek ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
The thesis describes the initial state of the computer network Basic Schools and Kindergartens Ohradní (ZŠMŠ Ohradní) in Prague 4 and then its reconstruction, which I largely contributed. ZŠMŠ Ohradní consists of four pavilions and from one building on the other side of the street. The aim of this study is to assess the initial state of the network and point out the shortcomings that we discovered. We found deficiencies in the operation stress tests, measurements and data cabling overall analysis. Original networks connectivity was 100Mb/s. Together with a colleague, we are network administrators. Furthermore, I am going to introduce a new form of network, which has identified deficiencies improved, by using on newer technologies. I will describe its structure, address allocation, active and passive components, and operated services. New network is capable of 1Gb/s, and its spine is going to be 10Gb/s soon. Benefits of this reconstruction is faster, more stable and more modern network that will facilitate the work of employees of ZŠMŠ Ohradní. To these improvements, I have mainly contributed by measurements. I participated in the design and implementation of new form of data network. I collaborated with fellow Poc to the configuration of active elements and network services in reconstructed network.

Design of processes of business department in IT company and measuring their performance
Schütz, Martin ; Oškrdal, Václav (advisor) ; Bruckner, Tomáš (referee)
The thesis deals with design of new processes of business department in IT company which provides server hosting, web hosting and domain registration services. These processes come from identification and analysis of current processes and the theory of business department management. Key Performance Indicators (KPIs) were set for selected processes which can be used for managing the company as a whole. Models of processes were created due to EPC notation. New processes were designed to continuously create data in CRM information system providing evidential and information support necessary for business department management, including the possibility of measuring its performance. Processes also automatize often repetitive activities and provide relevant information to other affected business units within the company. Contribution of the thesis lies in results of analysis of current identified processes containing solution proposals of discovered problems and newly created process models. Both can be used as a pattern for optimization of current processes in already existing organization or for designing new process models in new organization in the same or similar field of business.

CRM System Optimization
Fučík, Ivan ; Mildeová, Stanislava (advisor)
This thesis is focused on CRM solutions in small and medium-sized organizations with respect to the quality of their customer relationship. The main goal of this work is to design an optimal CRM solution in the environment of real organization. To achieve this goal it is necessary to understand the theoretical basis of several topics, such as organizations and their relationship with customers, CRM systems, their features and trends. On the basis of these theoretical topics it is possible to analyze current CRM solution in the organization. From the data obtained by the methods of observation and controlled interview it was possible to prepare a design for optimal CRM solution. This optimal solution comes also from user and organization requirements. The optimal CRM solution saves time and costs associated with current CRM solution and replaces existing and ineffective CRM tools.

Height measurement in the northern area of mining areas Doubrava and Karviná Mines In 2016
Kajzar, Vlastimil ; Waclawik, Petr ; Staš, Lubomír
In the northern area of mining areas Doubrava and Karvina mines on the border RA Detmarovice and Doubrava are implemented, the mining activities. For this reason, in order to detect possible effects of the mine to the surface and surface objects twice a year height focuses, points in this area stable. From 2014 he was a contractor for these works chosen by the Institute of Geonics, v.v.i., Ostrava. In August and November 2016 survey conducted campaigns planned this year, during which it conducted a total of 4 highrise focus of inter-related leveling routes, which are formed by these points. Highrise points are stabilized in the area of interest in several ways - usually in steel design height marks on buildings, then as an iron bolt concreted in the ground or using nails driven into the concrete foundation or other alternative means. Distribution points in the area of interest is indicative captured in the map appendix. Existing trace and focus points are highlighted in green, yellow trace inaccessible points, refocused points in red and violet points that have occurred to their long term disablement or destruction. Each zaměřovaných points in order to trace the terrain carefully documented (GPS coordinates, photos, text description) and registered. These documents are available from the contractor.
