Psychoacoustical Measurement of Binaural Hearing Characteristics
Novotný, Ota ; Trzos, Michal (referee) ; Schimmel, Jiří (advisor)
This diploma thesis deals with a binaural hearing issues (it means hearing by both of ears), a human hearing ability to locate position of a sound source at three-dimensional space and parameters that affect this ability. In the second part, it focuses on psychoacoustic experiment, its main features and errors that can occur and which affect a results credibility. Method of pair comparisons is described more closely here. The last part of this thesis describes a technical solution of experiment in Java environment. The application should have a graphical interface and should be able to register a new user and perform a psychoacoustical experiment. The process of experiment is following. The aplication selects a random position of defined virtual sound source on the defined range and it plays this sound into headphones on button click. The users task is to set the application controls, representing a virtual sound source position, that way, where the user hear the sound come from. On another button click the application plays the same sound, but this sound comes from application controls set position (set by user). User compares this pair of sounds and modifies the position of second sound source until these two positions are same. The application stores these results for later processing on another button click. Principles of generating testing sound sources (sine wave, narrowband noise and sound file with wav extension) and their 3D positioning by measured head model impulse responses correlation are described thereinafter. An ability of human hearing system to locate a virtual sound source in dependence on sound parameters is discussed in conclusion.

Bubal, Jan ; Svobodová, Doubravka (advisor) ; Gregorini, Bedřich (referee)
ELEMENTARY GUIDE TO TECHNICAL EQUIPMENT OF SMALL THEATRE GROUPS, VENUES AND EVENTS
In my bachelor thesis I dissert on relationship of stage and audience, its technical equipment, sound and lightning systems from an angle of an incipient theatre producer and manager. This work should be an elementary guide that helps in organizing small festivals, site-specific and other similar projects. Finally it should work as an instruction manual helping to technically equip a small theatre venue and bring a reader brief awareness of the economical aspect of setting up the venue. Main emphasis lies on lighting technologies, particular types of lights and regularities of its usage. This thesis also contains large amount of graphical documentation and basic technical specification.

On a Personal Plane/Delimitation
Komoňová, Pavlína ; Koťátková, Eva (referee) ; Ambrůz, Jan (advisor)
A liquid and a vessel it is one of the stimuli for my final work. Opportunity arose with the installation process Austerlitz castle in the cellar and I exchanged a bright, warm room for a dark, cool environment. Walk up on the wooden pier, which progressively increases until it reaches a maximum height of 25 cm. Going through the corridor and you come into the space unexpectedly increases, the wooden floor beneath you slightly swings. Discouraged, boards under waggling your weight because they are screwed and light shines through them that you engage. Maybe now examine options, and then you go further narrowing down the corridor outside. Now you have gone through my inside.

Antenna for in-car UWB communication
Špůrek, Jan ; Puskely, Jan (referee) ; Raida, Zbyněk (advisor)
This bachelor’s thesis is focused on the design of a wireless UWB network inside a car. The project is divided into three parts. In the first part, we describe the design of suitable antennas and feeding structures. The second part is focused on the simulation of a reciprocal communication for each type of the antenna in free space. In the third part, we investigate the effect of interference caused by near parts of the car for each type of the antenna. The results are then evaluated and the most suitable antenna is chosen for realization. The fourth part describes modifications of the antenna for SMA connector, which is necessary for measurement. In the fifth part we discuss measured results and compare them with assumptions from simulations. Results of the thesis are summarized in the conclusion.

Immediate early genes as a tool for study of spatial orientation and memory
Bláhová, Veronika ; Němec, Pavel (advisor) ; Telenský, Petr (referee)
Properties of the environment, spatial orientation cues and time-shifting movements are essential for cognitive maps. The understanding of how both space and the animal's position within that space are represented in the brain has been significantly advanced by the discoveries of four principal neuronal types: the place cells, the head direction cells, the grid cells and border cells. Their activity being driven by both allothetic (visual and non-visual landmarks), and idiothetic cues (internal movement cues based on proprioceptive and vestibular information). Brain regions containing aforementioned types of neurons constitute complex spatial representation system. Immediate early genes (IEGs) and their products became sophisticated tool for the study of neural substrate of spatial orientation including magnetic orientation. For further research it is unavoidable to uncover the dynamic of processes related to IEGs in order to better understanding the functions of brain centres involved in rodent navigation circuit. This work summarises our knowledge about spatial orientation of the vertebrates aimed at rodents, in context with detection of IEGs expression as activity markers in neural substrate. There are described most common experimental mazes and most frequent detection methods used in connection with...

Dining Outdoors
Trčková, Jitka ; Buganská, Tamara (referee) ; Zdařil, Zdeněk (advisor)
Feasting which contains plates, cups, cutlery, quilt and canvas bags as a cover. Bags are made for cyclists, pedestrians and easily used for more demanding users with car. Set is designed for 4 people. QUILT, shape is proceed from square, place for feasting is moved from center of quilt to the longest side on edge. Users are closer together and still can see each other in conversation. Place for feasting is highlighted with colored rubber segments which also help balance surface. PLATES are made from two parts - dinner plate and soup plate. Inside the soup plate is space for cutlery storage. CUTLERY is consisted of desert spoon, fokr and knife. All these three parts have a groove which is enabling fix cutlery together. CUPS, shape is proceed from accidence of hole project. There is a small point on the outside which helps to use the cup out of the quilt without capsizing of drink. This point is designed for sticking in the ground. BAGS have classic oblong cut, they are designed for easy use for cyclists (2 pieces). It is consisted also strap for pedestrian. There are two smaller pockets for set of plates and set of cups inside one of the bag.

The graveyard as a literary place in the 19th century Czech fiction
Procházková, Žaneta ; Menclová, Věra (referee) ; Vaněk, Václav (advisor)
V české epice nacházíme nejrůznější přístupy autorů ke smrti, odrážejí tak onu mozaikovitost názorů člověka 19. století, navíc se v nich mísí prvky kulturně sociální s prvky předchozí literární tradice, přitom jde, jak jsme si ukázali, o vlivy pocházející z různých historických období. Hřbitov bývá označován jako zahrada mrtvých, svaté pole, místo posledního odpočinku, příbytek věčnosti… Tato pojmenování v sobě skrývají některé z možných přístupů k prostoru hřbitova, popř. hrobu. V epice se setkáváme s koncepcí hřbitova jako zahrady či pole, dále se hřbitovemlabyrintem a (okrajově) hřbitovem-bytostí, hrob bývá přirovnáván k lůnu, loži či příbytku. V zásadě můžeme vypozorovat tři základní situace, kde a za jakých okolností se v české epice objevuje prostor hřbitova: hřbitov vytváří hlavní kulisu děje, vrací se jako leitmotiv nebo se vyskytne v ději pouze jednou, vždy však na místě výrazně exponovaném. Na umístění v rámci textu pak závisí funkce, kterou prostor hřbitova plní.

The view on a relationship aspects between a man and a guide dog
Borská, Klára ; Vodáčková, Daniela (advisor) ; Šafránková, Pavla (referee)
Ve své práci jsem se zaměřila na vztah člověka a vodicího psa. Cílem mé práce bylo zjistit, jak takový vztah může fungovat a jaké jsou jeho hlavní prvky. Věnovala jsem se otázkám pozitivních i negativních stránek soužití a jeho celkovému hodnocení majiteli vodicích psů. Důležitým okruhem byla i motivace k pořízení vodicího psa. Teoretickým základem mé práce jsou historické souvislosti vztahu člověka a psa a jeho vývoje, včetně rozvoje výcviku psů jako pomocníků člověka. Dále jsem se věnovala popisu druhů zrakového postižení, průběhu výcviku psa i legislativě ve vztahu k vodicím psům. Informace ohledně soužití s vodicím psem jsem získala prostřednictvím rozhovorů s respondenty, kterými byli tři muži a sedm žen. Z rozhovorů i prostudovaných materiálů jsem dospěla k závěru, že soužití člověka s vodicím psem je pro člověka se zrakovým postižením velkým přínosem. Z rozhovorů vyplývá, že tento vztah přispívá ke zlepšení kvality života člověka s postižením. Vodicí pes je zdrojem pocitu bezpečí z hlediska pohybu v prostoru a zároveň je člověku společníkem a přítelem.
