Texturní a barevné vlastnosti sýrů ošetřených extracelulárními enzymy
Jašková, Jana
Tato diplomová práce se zabývá texturními a barevnými vlastnostmi sýrů ošetřenými extracelulárním enzymem. Vzorky sýrů zrály po dobu třech týdnů. Pro stanovení texturních vlastností sýrů byla použita penetrační a kompresní metoda. Barva sýrů byla měřena na spektrofotometru CM 3500d. Nejnižší pevnost stanovenou penetrační metodou měl vzorek s lakázou po výrobě (0,55 ± 0,07 N) a nejvyšší pevnost vykazovat kontrolní vzorek, který zrál jeden týden (1,31 ± 0,14 N). Nejnižší pevnost stanovenou kompresní metodou měl vzorek s lakázou, který zrál dva týdny (3,11 ± 1,07 N) a nejvyšší pevnost měl kontrolní vzorek sýru zrající tři týdny (12,28 ± 2,36 N). Hodnoty L*(D65) se pohybovaly u všech vzorků v rozmezí od 72,89 ± 0,31 do 87,76 ± 0,01, hodnoty a*(D65) od -1,95 ± 0,01 do 0,66 ± 0,05 a hodnoty b*(D65) byly naměřeny mezi 6,73 ± 0,35 a 20,93 ± 0,03. Ošetření enzymem lakáza nemělo významný vliv na pevnost a barvu vzorků sýrů.

Conventional and unconventional energy storage technologies
Mikulec, Ondřej ; Rujbrová, Šárka (oponent) ; Jašková, Jana (vedoucí práce)
This bachelor thesis focuses on the systems used for the storage of electrical energy from the conventional methods being already integrated, to more unconventional ones. This thesis gives a basic explanation of these systems and their integration into the power grid. In the next part of the thesis, the focus is on their advantages and disadvantages from various points of view. The last part of the thesis pays close attention to the direct comparison of the given methods to further outline their main weakness while also showing their strong parts which makes them better for future development and additional integration.

Methods of websites localization
Nikulcha, Maxim ; Jašková, Jana (oponent) ; Šťastná, Dagmar (vedoucí práce)
The phenomenon of companies seeking to expand their markets to a global scale has been a trend for a long time. In the early days of international trade, it was quite difficult to establish connections between countries due to the lack of reliable communication systems. However, the situation changed when the Internet became a global means of communication. It introduced a new way of selling products and services using websites. The purpose of this paper is to expand the current understanding of web localization. In this paper, the definition of web localization, its origins and the difference between localization and cultural adaptation are presented. It also defines the process of localization within Translation Studies. Furthermore, it describes the most crucial methods of localization, examines typical localization errors, and provides best practice guidelines. The practical part analyzes the localization of selected websites with a focus on their functionality. This would help developers and translators to better understand the process of website localization and prevent further mistakes in their future work.

Nasycené mastné kyseliny v rostlinných olejích: zdroje a vliv na lidské zdraví
Jašková, Jana
Tato bakalářská práce se zabývá rostlinnými oleji, které obsahují vyšší podíl nasycených mastných kyselin. Cílem bylo zjistit jejich zdroje a vliv na lidské zdraví. Jedná se o literární rešerši, která popisuje zařazení nasycených mastných kyselin mezi lipidy a informuje o nejvýznamnějších nasycených mastných kyselinách. Dále vymezuje nejčastější rostlinné oleje s převažující stearovou, palmitovou nebo laurovou kyselinou. V neposlední řade popisuje jejich pěstování a následné zpracování na výrobu oleje. V závěru práce jsou formulovány onemocnění spojené s nasycenými mastnými kyselinami, zejména zvýšení hladiny LDL cholesterolu a jeho vliv na lidské zdraví. Celkově téma lipidů a nasycených mastných kyselin není zcela prozkoumáno a objevují se rozporuplné studie o tom, jak působí na lidské zdraví a jak by se měli omezit v lidské stravě.

Robots of the present and the future
Rehák, Jozef ; Langerová, Petra (oponent) ; Jašková, Jana (vedoucí práce)
This semestral thesis is concentrated on the topic of robots of the present and the future. The objective of the thesis is to introduce robots to a reader and theoretically describe the state of robots today and predictions for the future of robotics. At the beginning of the work is a brief description of the history of robots and explains the name they were given. Subsequently, the current state of robotics is described, and the robots are divided into groups that best suit their abilities. Moreover, predictions of the future of robotics are discussed together with the technological singularity. In addition, these discussed predictions show the potential of robotics to become part of the very existence of humans by becoming cyborgs or by digitizing their mind and uploading it to the cloud. In this way, the possibility of immortality or at least prolongation of life is presented. Lastly, there is possibly the first example of a product of the future, which will be mass-produced.

Cryptocurrency – a modern kind of money
Petrenec, Vojtěch ; Baumgartnerová, Alena (oponent) ; Jašková, Jana (vedoucí práce)
Cryptocurrency has become a well-known phenomenon in the worlds of banking and electronic payments, but it is still a mystery to the general public, and not everything is explained so that anybody can trade with it. The focus of this thesis is on cryptocurrency. The study concentrates on the origins of cryptocurrencies, the principles on which their security works, why their transactions are untraceable, and how these transfers are carried out. Subsequently, the thesis deals with where the owner can store his cryptocurrencies, what types of wallets exist, what cryptocurrency mining deals with and what can be obtained through it. Individual cryptocurrencies are discussed in the second chapter of this thesis, including their history, and which wallets are appropriate for each coin. Furthermore, fiat currencies are discussed, including their history and the economic functions they perform. Lastly, these economic functions are applied to cryptocurrency. The purpose of this thesis is to gain a greater understanding of cryptocurrencies, including what they are, how they work, and how to deal with them as well as how they differ from fiat currency.

The Technology of Subtitles in Films and other Media
Tobiášová, Eliška ; Jašková, Jana (oponent) ; Froehling, Kenneth (vedoucí práce)
The purpose of the bachelor’s thesis is to explore subtitling technology. This is analysed from a historical, present, and future perspective. The research also mentions specific ways of using subtitles for certain types of media and it also includes an analysis of the target groups for which the subtitles are intended. In addition to theoretical research of subtitling technology, an experiment is conducted to assess the accuracy of subtitling between machine-generated subtitles, professional work, and amateur work. This is achieved by comparing subtitles from the same film scenes side by side in tables. The result of the research, which is derived from the criteria mentioned in the work, shows that professional subtitles are the most reliable way.
