Column-oriented and Image Data Format Benchmarks
Tarageľ, Marián ; Bartl, Vojtěch (referee) ; Špaňhel, Jakub (advisor)
Cieľom tejto bakalárskej práce je ohodnotiť rôzne dátové formáty pre ukladanie tabulárnych a obrazových dát. K zvládnutiu tejto úlohy táto práca navrhuje nový benchmark dátových formátov. Benchmark je rozdelený do troch benchmarkových skupín. Tie zahŕňajú benchmark nekomprimovaných tabulárnych formátov, komprimovaných tabulárnych formátov a benchmark obrazových úložísk. Celkové výsledky tabulárnych benchmarkov naznačujú, že najlepší tabulárny formát pre rýchle ukladanie a čítanie je Feather a najviac pamäťovo efektívny je Parquet. Výsledky benchmarkov ukladania obrázkov ukazujú, že najrýchlejšie úložisko obrázkov je v SQLite a najmenej miesta vyžaduje formát PNG. Výsledky tejto práce môžu prispieť k lepšiemu pochopeniu správania sa rôznych dátových formátov a pomôcť pri výbere správneho formátu pre tabulárne a obrazové dáta.

Product Data Visualization in PNC Build System
Korytár, Patrik ; Janoušek, Vladimír (referee) ; Kočí, Radek (advisor)
Cieľom tejto bakalárskej práce je zlepšiť vizualizáciu dát súvisiacich s produktami build systému PNC na jeho novom webovom používateľskom rozhraní. Hlavné vizualizačné prvky zahŕňajú tabuľky, grafy, sieťové grafy a palubné panely. Táto práca analyzuje vstupy od používateľov build systému PNC, aby sa zohľadnili skutočné potreby používateľov. Na základe analýzy bol vytvorený dizajn pre úplne nové komponenty používateľského rozhrania a niektoré z už existujúcich boli prepracované. Na ilustráciu nového dizajnu sa vytvorili nákresy. Navrhnuté boli nové koncové body REST API pre dáta vyžadované novými komponentami. Nové funkcie boli následne implementované. Implementačný jazyk je TypeScript. Hlavné knižnice zahŕňajú React, Chart.js, Sigma.js a Graphology. Ako výsledok má teraz nové používateľské rozhranie systému PNC nové funkcie, ktoré pomáhajú s používaním stránok súvisiacich s produktami. Implementácia je tiež ľahko rozšíriteľná pre viac vizualizácií tohto druhu.

Analytical Dashboard for Indoor Locating System
Petrovič, Lukáš ; Ščuglík, František (referee) ; Veselý, Vladimír (advisor)
The main purpose of this work is to create an application which will provide visualisation of historical data from position sensors. The data are being obtained from closed spaces, for example shops, gymnasiums or halls. These data are valuable but without easily usable visualisation they will lose their potential. Right visualisation allows user to better evaluate situation which the data represents. Result of this work is a tool with which the user is able to easily analyse data gained in certain time interval. For the needs of analysis, the application provides various kinds of data representations, which assign the data specific purpose. Data might be presented in graphs for example for the purpose of representation of the total overcomed distance of monitored object. They can also be used in maps which provide good representation of positions due to monitored area. All created visualization elements are put into interactive blocks. These blocks make up almost whole control panel. It is easy to manipulate with these blocks and to edit created visualisation with their help.

Hanzély, Oskár ; Bidlo, Michal (referee) ; Jaroš, Jiří (advisor)
This thesis deals with routing processes of computer networks, overview of netwrok topologies and commonly used routing algorythms. It includes detailed description of created application to graphycal dysplay of networks schemes and routing. It contains transformation process of some schemes and the visualisation of all routing steps like an animation. The potency of usage and future development is commented briefly.

Visualising CPU Activity
Ďurčo, Marián ; Češka, Milan (referee) ; Vojnar, Tomáš (advisor)
This thesis is intended to be a complement for learning about the RISC pipeline. Product of this thesis is a web application. After reviewing various tools and libraries suitable for this work, we have chosen two main libraries React and Redux. The created solution allows the instruction flow to be displayed in the RISC pipeline as well as states of the registers and the memory. It makes easy to perform transitions between the various parts of the visualization. This visualization allows a basic understanding of the RISC pipeline principles and also individual assembly instructions.

Sentiment Analysis in Automotive Industry
Bezák, Adam ; Otrusina, Lubomír (referee) ; Smrž, Pavel (advisor)
The main theme of this thesis is to familiarize with the basic methods of sentiment analysis on social networks. Thesis’s theme is aimed on the automotive industry, although this prinicipal can be used in any different examined branch. The basis of the practical part is to obtain data from the social networks, analyze them and then index them into ElasticSearch database. Another goal of the thesis is to visualize these data by means of a web portal. Created web portal provides various statistics of the leading automobile brands, an overview of new trends or the aspect visualization of the individual cars.
