Wheelchair control using EEG signal classification
Malý, Lukáš ; Sadovský, Petr (referee) ; Žalud, Luděk (advisor)
Tato diplomová práce představuje koncept elektrického invalidního vozíku ovládaného lidskou myslí. Tento koncept je určen pro osoby, které elektrický invalidní vozík nemohou ovládat klasickými způsoby, jakým je například joystick. V práci jsou popsány čtyři hlavní komponenty konceptu: elektroencefalograf, brain-computer interface (rozhraní mozek-počítač), systém sdílené kontroly a samotný elektrický invalidní vozík. V textu je představena použitá metodologie a výsledky provedených experimentů. V závěru jsou nastíněna doporučení pro budoucí vývoj.

Analysis of Economic Risk of Investment Project
Malý, Lukáš ; Holá, Michaela (referee) ; Hromádka, Vít (advisor)
This thesis focuses on considering of the investor economic risk during the preparation of the investment project including the financial plan, its evaluation and suggestions of proposals for risk reduction. Correct decisions on implementation or rejection of the project are based on the realistic financial plan. However, expenses and revenues are only implied and are burdened with some variability that leads to the risk of failure to achieve the planned values. To assess the acceptability of certain risks for the investor, an analysis of risk factors was conducted. The factors are first identified for their significance and potential negative impact, then the most risk factors are evaluated and determined whether it is necessary to further tracking or the risk to the investor is acceptable.

Toolbox for neuronal datasets
Malý, Lukáš ; Harabiš, Vratislav (referee) ; Lamoš, Martin (advisor)
The aim of this bachelor's thesis was to create toolbox for functional magnetic resonance (fMRI) and electroencefalography (EEG) data processing in MATLAB enviroment using SPM software package. The first part describes the physiological origin of these data at neuronal level, basics of magnetic resonance imaging, principles of fMRI experiment, preprocessing and processing of fMRI data, their interpretation, then function and principles of EEG are described and at the end is simultaneous EEG-fMRI described. In the second part of the thesis features of each tool from Neural Data Toolbox (NDTb) are described.

Justice and dignity in deciding on the allocation of scarce resources in the provision of medical care in a situation of scarcity.
Malý, Lukáš ; Fošum, Jan (advisor) ; Štica, Petr (referee)
The problem of allocation of scarce resources in the provision of curative - preventive care in the period lack includes many dimensions. Human dignity and justice can be understood as central concepts, with regard to the social teaching of the Catholic Church. The aim of the work is to describe the role and mutual relationship of both concepts and to offer a basic view of the topic of the allocation of rare resources in the contemporary discussion in the conditions of the Czech Republic. In this context, the question of justice with an emphasis on human dignity appears as a central theme. In the second part, on the normative level, the work is focused on the concept of inherent and contingent dignity, as two main lines of meaning. The importance of inherent dignity cannot be questioned in the context of medical ethics and bioethics. But is the concept of dignity attributed from the outside, based on certain characteristics, abilities and skills (the so-called contingent dignity) also relevant and what role can it play in the situation of scarce resources in the framework of their allocation? How can this category be understood given the need to prioritize in a situation of scarcity?

The Poetics of Space in The Alexandria Quartet.
Malý, Lukáš ; Bílek, Petr (advisor) ; Pokorný, Martin (referee)
Poetics of space in The Alexandria Quartet is created by multilevel structures. This poetics is closely connected to the main space of the story - Alexandria, which is at the same time one of the novel's topics. Each level is suggested in connection to various theoretical conceptions which are subsequently used for my own analysis. Alexandria is initially an aesthetic coulisse of the story which is portrayed by descriptive passages. Strongly subjective and lyrical descriptions of the city establish overall impression of the story and potentially support reader's experiential illusion. Alexandria and its specificity is further modulated and thematised by its special macroscopic conditions which border Alexandria as an autonomous fictional space with its own rules within the novel's fictional world. Part of poetics of the space in this novel is also portraying spatio-temporal aspect of the reality (chronotope) no only on the level of the story, but also on the level of storytelling. Alexandria is further explicit rhetoric and also through semantic indexation personified and enters semantic relations with the main characters and events. Each level is complementary to another and all are part of the semantic gesture of the novel. Alexandria becomes a separate symbol, mythical entity which importance is...

Study of biological activity of alkaloids isolated from Fumaria officinalis L. (Fumariaceae) II.
Malý, Lukáš ; Chlebek, Jakub (advisor) ; Opletal, Lubomír (referee)
Malý, L.: Study of biological activity of alkaloids isolated from Fumaria officinalis L. (Fumariaceae) II. Diploma Thesis, Charles University in Prague, Faculty of Pharmacy in Hradec Králové, Department of Pharmaceutical Botany and Ecology, Hradec Králové 2014, 49 pp. Obtained diethylether extract of Fumaria officinalis L. was separated to fractions in column chromatography with petrol, chloroform and ethanol. Preparative TLC and crystalisation led to isolation of five alkaloids from fraction. Alkaloids were identified by GC-MS and NMR specters, optical rotation and melting point as protopine, cryptopine, (-)-fumaricine, (+)-fumariline and (+)-parfumidine. Isolated alkaloids were tested for their inhibition activity towards acetyl- and butyrylcholinesterase and towards prolyloligopeptidase. Activities were compared with standards. Natural inhibitor galanthamine showed IC50 AChE 1.710 ± 0.065 µM, IC50 BuChE 42.30 ± 1.30 µM. Best inhibition activity showed protopine (IC50 AChE 345.4 ± 24 µM, IC50 BuChE 239.6 ± 22.3 µM) and cryptopine (IC50 AChE 477.71 ± 47.33 µM, IC50 BuChE 270.82 ± 39.12 µM). The highest prolyloligopeptidase inhibition activity showed (+)-parfumidine with IC50 POP 99.2 µM, which was more active than used natural inhibitor baicaline (IC50 POP 605.9 ± 0.021 µM). Synthetic POP...
