Asynchronous MQTT Client Library for Embedded Devices Running on Drogue-IoT Firmware
Babec, Ondřej ; Lichtner, Ondrej (referee) ; Pluskal, Jan (advisor)
IoT je odvětví informatiky, které v posledních letech masivně expanduje. V dnešním světě je IoT všude kolem nás. Jsou to chytré žárovky a doplňky do domácnosti, ale také tisíce zařízení v průmyslových objektech. Nedílnou součástí IoT jsou protokoly pro zasílání zpráv, které umožňují komunikaci komunikaci s těmito zařízeními. Dnes již existuje mnoho projektů, které umoňují integraci IoT zařízení a následné cloudové zpracování jejich zpráv. Jedním z těchto projektů je Drogue-IoT. Tento open-source projekt umožňuje vytvářet firemní cloudové řešení, ale také firmware pro vestavné zařízení. Jednou z limitací tohoto projektu je nepřítomnost klientské aplikace podporující zasílání zpráv pomocí protokolu MQTT. Právě tato klientská aplikace je tématem této práce. Práce zahrnuje návrh a implementaci klienta protokolu MQTT pro vestavěná zařízení v jazyce Rust, který doposud neexistuje. Řešení je demonstrováno pomocí sestrojeného zařízení. Výsledná práce vyhodnocuje implementaci klienta a obsahuje návrhy na budoucí vylepšení práce.

Assessing the contribution of bioeconomy to the economic growth and development of Ghana: analysis of the fishery industry
Omari, Frank Agyekum
The concept of bioeconomy and its importance in achieving economic growth while protecting the environment has gained significant attention on the research and policy front in recent years. The fisheries sector in Ghana is economically important and provides employment opportunities, but there is a lack of understanding on how to effectively adopt the bioeconomy paradigm in the sector. This study aims to identify the key factors such as employee motivation, research and innovation, knowledge and skills, regulatory quality, and the production process quality facilitating bioeconomy transition. The scope of the study focuses on exploring the nature of bioeconomy in Ghana in general and the contribution of bioeconomy to the growth of the economy and the development of Ghana. The research methodology relied on both primary and secondary data source and the study sample consisted of management and staff in the fishery sector. Utilizing structural equation modeling (SEM), SMARTPLS 4 software was employed to examine the data. Findings of this study revealed that, key drivers such as motivation of employees, knowledge and skills, research and innovation, regulatory quality, and the quality of the production process all tested significant to the dependent variable of organizational performance. The study provides significant findings regarding the factors, challenges, and approaches involved in the successful implementation of bioeconomy in Ghana’s fisheries industry. Based on the findings, important actions to enable a seamless transition include the implementation of strong financial mechanisms, formulation of supportive policy frameworks, and promoting research and development initiatives.

Struktura sukcesních porostů a růstové vlastnosti břízy bělokoré (Betula pendula Roth) na exponovaném stanovišti
Bardoň, Karel
This bachelor’s thesis describes the structure of naturally occurring stands dominated by white birch (Betula Pendula Roth) on two exposed sites. The site marked as "Hlubočec" represents the situation of the Nizký Jeseník, the site marked as "Krásná" the situation of the Moravian-Silesian Beskydy. Both areas have been inventorised and described in terms of the growth potential of birch as well as the current presence of other tree species, including the so-called target species in the case of "Hlubočec". The growing potential was, as expected, in the more trophic site of Hlubočec. Here, there are target individuals of grown out European beech and forest oak, as well as relatively abundant occurrences of natural regeneration of Norway spruce, white birch, and occasionally also bird crane and European beech. The 'Krásná' site represents an area that has been neglected in the past, affected by erosion and degradation, where the birch tree mainly serves the function of soil protection and habitat restoration.

Intrauterinní růstová retardace selat
Kršová, Eliška
This bachelor's thesis focuses on intrauterine growth restriction of piglets. The first part of the thesis deals with sow hybridization, the creation of super-fertile sow lines, and how breeding can affect litter size. The second part focuses on the issues of highly fertile sows, particularly in terms of nutrition, housing, delivery, lactation, weaning, and preparation for the next pregnancy. The third part focuses on intrauterine growth restriction of piglets. This section describes what this condition means and what can influence it. The fourth part deals with problems in piglets with intrauterine growth restriction. Methods for the application of artificial milk, the use of surrogate sows, or split nursing are described here.

Využití druhu Terminalia brownii pro zalesňování v jižní Etiopii
Raab, Jakub
This work is primarily focused on determining the growth capacity of Terminalia brownii species during plantations under mechanical erosion control measures in the southern region of Ethiopia. The aim of the work is therefore to determine the growth capacity and its properties in two standard types of erosion control measures and compare them with the growth characteristics of natural regeneration occurring in the study area. To address this issue, a field research was organized in Arba Minch, Ethiopia, where plantations of the investigated species were implemented. The area of interest was divided into test plots, where the number of planted seedlings, the number of growing individuals, and the number of naturally regenerated pieces were counted. The height and stem diameter at a height of 15 cm were measured for each growing individual. The results evaluate the mortality of the species in various erosion control measures and its growth characteristics. The work thus demonstrates the growth capacity and the dependence of height on stem diameter for different forms of erosion control measures.

Vyhodnocení růstové intenzity jalovic na jejich reprodukční a užitkové vlastnosti
Voldánová, Eliška
The main aim of this diploma thesis was to evaluate effects of holstein heifers growth factors and their subsequent reproduction and milk production. The heifers were rear in the same conditions and also their subsequet reproduction and milk production took place in the same stable. No significant (p> 0,05) differences in the weight of heifers weighed a tage of 225, 335, 445 and 580 days were demonstrated for heifers after the sires of the line NXB and for heifers after the sires of the line NEO. Similary, there was no evidence (p> 0,05) of the influence of the order of mother´s lactation on the growth ability of the heifers. From the reproductive indicators of the heifers, the age of embed, the age of calving and the insemination index were monitored. The heifers were most often embed at the age of 13 months. The best age if calving was from the age of 22 to 23 months. Significantly (p <0,05), the best insemination index was found out in heifers from mothers on the 4th and higher lactation (1,17). The best insemination index was shown on the group of heifers which weighed during their time of embed between 400 to 440 kg. The milk production was better after the sires of the line NXB (10556 kg). In terms of grouping by maternal lactation, the best performance was held by heifers after the mother on the 2nd lactation. The content of fat was the similar (about 4 %) in all groups of heifers. The content of protein was similar for all groups of heifers (3,36 %). The best milk production was achieved by heifers calved at the age of 23–24 months. This group had the highest content of fat and proteins. The most favorable milk yield was shown in heifers weighing between 400 to 440 kg at the time of embeding. This group also had the highest fat content, but conversely the lowest protein content.
