Dashboard for Smart Home Status Focused on Low Consumption Installations
Fišer, Tomáš ; Hynek, Jiří (referee) ; John, Petr (advisor)
In the rapidly evolving concept of IoT, or a network consisting of physical devices with electronic and software capabilities to interconnect and collaborate to perform autonomous actions without human intervention, dashboards are an important element for users, providing data visualizations and controls over data. This work deals with the creation of a dashboard that has as main goals low energy consumption compared to traditional solutions, simple control interface and clear data visualization. It tries to meet the parameter of low power consumption by using energy efficient computing hardware, ESP32 microcontroller and by using E-ink display panel which again has low power consumption. The resulting dashboard should be able to run on batteries for long periods of time without the need to replace or recharge the batteries.

Remotely Managed Low-Energy Information Display
Petruška, Zdenko ; Mrázek, Vojtěch (referee) ; Goldmann, Tomáš (advisor)
The main goal of this thesis is to create visualization panel and an app used for management of content on this panel. Visualization panel is composed of a platform ESP32 and an E-ink display. The panel and the app communicate with each other using wireless connection. The app is written using Django web framework. The app provides management of multiple panels and displayed content can be shared by panels.

Control system for drip irrigation
Zíka, Radim ; Benešl, Tomáš (referee) ; Bradáč, Zdeněk (advisor)
The bachelor thesis deals with designing drip irrigation control system. Aim of this thesis is realisation of microcontroler system which enables scheduled control of multiple branches of drip irrigation in an orchard. The design is focused on keeping the power consumption of the circuitry as low as possible. Theoretical part of this thesis focuses on research on drip irrigation and on low power circuit design theory. Practical part of thesis covers microcontroler system design, schematic design, printed circuit board design, revival of designed PCB and designing its control software.

Reader's perception of printed and displayed text
Piskáčková, Klára ; Drobíková, Barbora (advisor) ; Bouda, Tomáš (referee)
(in English): This thesis is conceived as a metareview of research on differences in perception, understanding and retention of text on various display media. It summarizes the results of the most interesting and most relevant research on this topic conducted since the 80s to the present. Even though it is difficult to summarize the results of individual studies, mainly because of differences in research methodology and differently chosen tested samples, we can say that the main finding of this metareview is that display technologies that are available these days have no negative effect on eye fatigue, reading speed, perception, understanding or retention of text. Theoretical part of this thesis is followed by practical part that consists of three short experiments performed on a small sample of participants. First of those experiments studies differences in reading comprehension and retention among high school students, second experiment focuses on differences in reading speed on different media and subjective evaluation of eye fatigue, and the third experiment is an online form about subjective preferences of study materials among learners.

Books as a medium and their role in contemporary world - paper or screen?
Piskáčková, Klára ; Halada, Jan (advisor) ; Vlček, JIří (referee)
The purpose of this work is to analyze the newly grown phenomenon of electronic books and electronic publishing, to map consequences of e-books in relation to paper books and to describe its pros and cons. Also, this work tries to compare ebook readers presently available on Czech market, and to make a comparison of most frequently used e-book formats. The future of e-books in the Czech Republic can be inestimable, but this work gives the opinions of some Czech publishers, booksellers and authors, trying to suggest how the future may look like.

Czech Electronic Book Market – Obstacles and Opportunities
Šperková, Lucie ; Koubský, Petr (advisor) ; Brodský, Jiří (referee)
This master dissertation "Czech Electronic Book Market -- Obstacles and Opportunities" analyzes Czech market with e-books. The aim is to provide a comprehensive overview of the current situation on the market in terms of technologies, distribution models and legal issues. It describes commercial, free and illegal sources in the market, including a description of digitisation projects in Czech libraries. The thesis also includes a theoretical introduction to e-books and their development in the past. Details are discussed, focusing on technology, modern electronic readers with electronic ink. For comparison, the thesis also analyzes the U.S. market with e-books. In analytical part the individual portals with e-books on the market, their supply and user interfaces are compared. The real example analyzes the costs of an e-book and its comparison to costs of a printed book. At the end of the thesis, alternative models of distribution requirements for establishment of a new portal with e-books are characterised, the Creative Commons licenses are described and the current trend of e-journals is mentioned. Finally, I suggest recommendations especially for sellers on the Czech market describe the advantages and disadvantages of e-books in terms of individual roles in the distribution model and estimate the future market development. More detailed information related to the comparison of different types of electronic ink, a list of electronic readers that are available on the Czech e-book market at this time and specific examples of various users' interfaces that are being used on Czech e-books portals can be found in Appendix.
