Processing and Storing IoT Data in Relational Databases with Application of Cloud Services
Hlava, Jakub ; Bartík, Vladimír (referee) ; Hynek, Jiří (advisor)
Smart cities and systems for their management are constantly producing great amount of data, which needs to be processed and stored. The goal of this Bachelor's thesis is to create a tool, which will make developers able to test influence of this amount of data on their system, especially on database server. Then they will be able to adjust their cloud infrastructure for assumed level of load before it's real-world deployment. The tool is developed using Python programming language as collection of components which makes scalable load testing possible from many places at the same time. Data about the course of test and about service of PostgreSQL database server is collected by the tool during testing. Course of the test can be controlled and monitored by user using integrated web interface, which also visualizes collected data in form of charts. The tool was created in cooperation with Logimic, s.r.o., tailored to their system for smart cities management.

Mollusca of the Czech Republic
Rindtová, Dita ; Hlava, Jakub (advisor) ; Křivská, Daniela (referee)
The Bachelor work Mollusca of the Czech Republic deals with basic information about molluscs occurring in the Czech Republic. In the research part of my work I deal with the anatomy of their bodies, shells and life cycles characteristic for the main representatives. In general characterization the work mentions endangered species listed in the Red List. Furthermore, the research part deals with ecology focused on shellfish incidence depending on the conditions of the ecosystem, introduction, and the methods of mollusc importance to humans.
The aim of the practical part was a faunal survey of selected localities contaminated by a man. This research was carried out in selected localities near the town of Příbram. It was the firsta research focused on the incidence of molluscs in these areas. The methodology of sample collection was carried out according to common methods of collecting molluscs and it is more specified in the work.
The own research was focused on characterisation of the areas (5 localities) where the collection was carried out. Thus there was formed a systematic overview of acquired kinds of terrestrial representatives according to designated habitats, taxonomic classification and specific characterisation of the species. A total of 514 individuals were processed belonging to 26 species of molluscs. The most numerous family had Vrásenkovití (Discidae) where the number of representatives climbed to 82 individuals. On the contrary Oxychilidae family, Skleněnkovití (Vitrinidae) and Melampovití (Ellobiidae) occured the least. There was found only one individual of each family.
In the last part of my work I deal with comparison of my research to the previous research carried out in Kokořínsko Reserve. This area has similar climatic conditions and the features of the ecosystems. The result of the comparison corresponds to the variability of the species found here.

Molluscan fauna of the Czech Republic
Cermanová, Michaela ; Hlava, Jakub (advisor) ; Husák, Tomáš (referee)
This thesis deals with the problems of molluscs on the area of the Czech Republic.
The introduction characterizes the tribe of molluscs and its history. The following part focuses on the morphology and anatomy of terrestrial and water molluscs, their ecology and biology. There is a detailed description of the life cycle of snails and clams, their way of life and food. The character of spread on the area of the Czech Republic and their migration connected with settlement of new biotopes was described at water molluscs. The following chapter deals with the question of collection and identification of molluscs, it describes several methods of collecting and identification of terrestrial and especially water molluscs.
A big part of the thesis is devoted to endangering of the mollusc fauna and negative influence of people on the malacofauna by creating new conditions in the landscape. The negative influences, by which people significantly change the landscape character, include for example forest clearing, construction of dams or longitudinal stream regulation. The last chapter describes the unoriginal species of terrestrial and water molluscs on the area of the Czech Republic, which represent another danger for our original malacofauna.

Entmophagy - insects as food of the future
Pondělíčková, Barbara ; Hlava, Jakub (advisor) ; Kulma, Martin (referee)
This bachelor thesis creates a summary of contemporary czech and the world's entomophagy. It contains knowledge about utilising insect as a source of food for people in
a form of literature research. This includes the history as well as contemporary reputation of entomophagy in the eyes of the public. The research part also describes the most notable species of insects utilised for consumtion today including a summary of the basic nutrition data. The following part of this paper studies farming insects distined for consumption and of course, safety concerns coming with consuming insects are also mentioned. In the end of the research part there is a list of several examples of different dishes made from insect.
In the practical part of this paper a questionnaire was created with the goal of mapping a describing the czech public's awareness of insect consumption the possibilities of its spreading. This questionnaire was realised particularly electronic (over the internet), additionally by personal questioning with the purpose of covering bigger variety of answers, especially to get answers from different age groups of the respondents. The recieved answers were analysed and the results were processed into graphs for easier reading.

Invertebrates in contaminated ecosystems - landfills
Vaníčková, Jana ; Hlava, Jakub (advisor) ; Husák, Tomáš (referee)
This bachelor thesis deals with invertebrates, in particular soil invertebrates, which inhabit the anthropogenically influenced enviroment at landfill of municipal waste.
In the theoretical part of this work the most common types of soil invertebrates and basic ecological concepts are described. The practical part included the processing of individual samples and also sampling sites description.
To obtain the material I have chosen four different landfills, where the soil samples were collected. The extraction of soil fauna was realized using Tullgrens extractors.The extracted samples were examined in lab conditions under binocular and the soil fauna were divided into taxonomic groups, according to their morphological characteristics.
Sampling locations did not represent a different ecosystems. The activities are carried out standardly, according to the law. There is a part of restoration area in each locality.
The aim of the practical part was to describe the composition of soil fauna communities in the landfill of municipal waste. Furthermore, this work deals with the comparison of individual sites and for a better interpretation, results are presented by tables and graphs. The observed diversity is interpreted using diversity and evenness indices.
The results show that the most dominant groups forming the fellowship of soil mites without incrusted body (in the work presented as Acari in general). Further, as another of the dominant group I found rich communities of the incrusted Oribatid mites and springtails (Collembola), which are considered as a typical soil fauna.
Most of these representatives was found in Sono landfill, on the other hand the minimum specimen were found in the Tušimice landfill. In the overall evaluation, samples did not represent significant differences in the composition of the soil invertebrates communities.
