Knowledge Discovery from Time Series
Krutý, Peter ; Burget, Radek (referee) ; Bartík, Vladimír (advisor)
This thesis is focused on the field of knowledge discovery from data, specifically from time series. Main objective is to research Python programming language support in this area and then design and implement an application that will allow to demonstrate and compare selected methods. Methods are demonstrated in experiments using appropriate data set. The output of the thesis is a comparison of methods for specific tasks and the application implementing selected methods.

Efficiency analysis of the heat source with heat pumps
Miklas, Václav ; Hejčík, Jiří (referee) ; Máša, Vítězslav (advisor)
This thesis is focused on the gross COP analysis of the heat source with heat pumps. In the first part, summary of the heat pump research including progressive technologies is presented. The main part is the case study dealing with the efficiency analysis of the heating system based on air source heat pumps. That includes theoretical formulation of the conditions which affects gross COP of the heat pumps. The main contribution is the evaluation of measured data. The outcome of evaluation is the average COP in the selected period. The outcome also includes dependence of the COP on different conditions and comparison of the evaluated COP and the theoretical one. Consequently, some methods for optimal operating of the heat source are recommended.

Data Mining with Python
Krestianková, Tamara ; Burgetová, Ivana (referee) ; Zendulka, Jaroslav (advisor)
This thesis deals with principles of data mining process, available Python packages for data mining and a demonstration of Python script capable of data analyisis focused on classification techniques. Created classifiers are able to classify subjects into two groups - healthy people and people suffering from Parkinson's disease - based on their biomedical vocal analysis data.

Analysis of the meteorological dates
Králík, Martin ; Čmiel, Vratislav (referee) ; Rozman, Jiří (advisor)
The aim of the bachelor’s thesis is to recognize the basics of atmospherical physics, the techniques and measuring instruments used in weather stations and the statistical analysis of three chosen meteorological parameters. Data analysis is made by using graphical display method, which is discussed later on.

Similarity Searching in Network Data
Hud, Jakub ; Krobot, Pavel (referee) ; Wrona, Jan (advisor)
This bachelor thesis is interested in analyzing IP flow records. IP flow record contains IP flow metadata of specific network communication such as IP addresses, port numbers, network protocol numbers and other. Main goal is to design and implement metrices to determine similarity of NetFlow records. At the beginning of this thesis is description of how to analyze great amount of data. Next there are shown network monitoring technicies and NetFlow. Other parts of this thesis are dedicated to design and implementation of data analysis using DBSCAN algorithm. Implementation of data analysis application is also part of this thesis. As a result, the application can be used to network scan detection using NetFlow data although the results are not very clear and contain a lot of legitimate communication.

Vibration analysis using a mobile phone accelerometer
Robek, Tomáš ; Huzlík, Rostislav (referee) ; Zuth, Daniel (advisor)
The bachelor thesis deals with the question whether or not measurements of vibrations can be taken with a mobile phone. For that purpose I made an experiment to compare data measured with a mobile phone and data measured with professional gauging equipment. I also focused on finding the most commonly used accelometer in mobile phones as well as on finding and comparing suitable mobile apps for recording vibrations with mobile phones.

Analysis of operation data for purposes of optimization
Slavíček, Martin ; Pavlas, Martin (referee) ; Touš, Michal (advisor)
This thesis deals with analysis of operation data for purposes of optimization. The thesis is divided into four chapters. First chapter focuses on present and future development in waste management legislation. It mainly deals with prevention, recycling and disposal of waste. Second chapter more closely describes waste-to-energy process. This chapter also describes the technology of municipal waste incinerator in Liberec, Termizo, a.s. Third chapter starts with description of tools used in design of the models based on operation data. Then the models for individual technological nodes are described. The last part is focused on building a complex model of Termizo using previous results.

Increasing the Effectiveness of Marketing Effort by Experimental Testing Methods
Lorková, Kristína ; Luhan, Jan (referee) ; Chalupský, Vladimír (advisor)
The thesis analyses the customer behavior of Kiwi.com, a global online retail company for booking flights and proposes marketing interventions to increase the conversion rates in various customer segments. The effectiveness of new behavioral interventions is tested against current marketing efforts using experimental A/B methods. Additionally, areas for further improvements are explored and a design of future product features and marketing behavioral interventions is proposed.
