Palm liveness detection and identification
Kala, Adam ; Goldmann, Tomáš (referee) ; Sakin, Martin (advisor)
This bachelor's thesis is focused on the detection of liveness of the human hand and its identification from multispectral images. The main goal of the work is the recognition of a living hand and its forgeries based on the information we have obtained, the finding of minutiae for palm identification and their use. The work describes techniques for cropping the area of interest, extracting characteristic features from the palm, and subsequent detection of liveness and identification of the person. Liveness detection success reached over 90% and person identification with a False Acceptance Rate (FAR) of less than 2% for selected datasets.

Sound of a low whisper
Krutsche, Karin ; Mladějovský, Josef (referee) ; Štindlová, Marie (advisor)
This bachelor's thesis examines the intersection of Christian themes with everyday life and draws inspiration directly from the Bible. The author focuses on her subjective interpretation of faith and reflects on the unexpected ways in which God's presence can manifest itself. Through her artwork, she visually depicts these themes, emphasizing the symbolism of light as a representation of God's transcendence.

GLASS, LIGHT, OPTICS
Ilič, Andrej ; Fulínová, Katarína Kudějová - (referee) ; Tobola, Ondřej (advisor)
The bachelor thesis deals with the development of a glass pendant interior light. The author utilizes optical principles to achieve the desired lighting effect while contextualizing the piece within an interior space. The light design is conceived as a modular system, enabling the customer to assemble multiple units as a construction kit. The result of the thesis is a prototype ready for mass production.

Usage of a luminance analyzer for analysis of natural light sources
Svoboda, Martin ; Baxant, Petr (referee) ; Novák, Filip (advisor)
This bachelor thesis is focused on the description of photometric quantities, presentation of methods of measuring illuminance and luminance, and explanation of the principle of devices used to measure these quantities. It also deals with the functions of the eye, its sensitivity, and changes in vision due to the alternation of day and night. The last chapter describes the origin of light in the natural sources of light, the Sun, the Moon, and fire, and then presents the measured values with their analysis.

Gemini
Holcrová, Eliška ; Nový, Vítězslav (referee) ; Marek, Jiří (advisor)
The point of the proposal is to revitalize a high school for physically disadvantaged kids and the schools surroundings. The work includes a proposal for the revitalization of the school, the concept of a school garden, and a café with a community center. The result will be a suitable space for education, relaxation, and development, not only for the school students but also for the local residents.

Measurement and creation of irradiance maps of irradiated surfaces
Šindelářová, Anna ; Jandová, Kristýna (referee) ; Křivík, Petr (advisor)
This diploma thesis deals with the measurement and creation of irradiance maps of irradiated surfaces. In the first part of the thesis, there are defined light and light radiation and its types and there are explained the basic concepts closely related to light radiation. Furthermore, this thesis also describes different types of radiation sources and their effect on irradiated surfaces. The theoretical part concludes with a chapter on radiation sensors, specifically pyranometers. In the second part of the thesis, the intensity of the radiation incident on the selected surface was measured by the selected radiation source, and then the radiation distribution was simulated using the Agilent VEE Pro 9.2 software environment. Subsequently, the measurement and its simulation were processed and evaluated.

Zlín FCK Technology
Morávek, Jakub ; Kudla, David (referee) ; Štěpán, Marek (advisor)
The diploma thesis deals with the design of a residential building in the area of Malenovice near Zlín, where a new residential complex is to be built on the land of the current Malenovice sawmill, situated in close proximity to a four-lane road. The concept of this proposal is based on a detailed examination of human cycles and their impact on people in everyday life in relation to architecture. From the life cycle through the annual cycle and especially the daily cycle, professionally referred to as the circadian rhythm. The building, with its idea concept, orientation to the cardinal points, zoning of the apartment and also the shape solution, responds to the needs of man in terms of light comfort and at the same time addresses the greatest efficiency of the technologies used precisely in relation to light comfort, the form solution also creates conditions at the terrace level for the meeting of a wide range of inhabitants of the house - creating diversity. It reduces the need to illuminate the space during the day with artificial lighting, and after dark it addresses artificial lighting with respect to human health, thus also reducing energy consumption.

Fragile Future
Jedličková, Eliška ; Sobotka, Jiří (referee) ; Gabriel, Michal (advisor)
Fragility, variability, immateriality... In my final master's thesis, I focused on the theme of fragility and shadow in visual art. I directed my initial idea towards the motif of fragility and transience. It's a topic that has interested me for quite some time. Where are the boundaries of fragility? How can the perception of this concept differ for each of us? Fragility can be understood as a certain material property, but also as an internal matter. In connection with this theme, I decided to work with shadow, which, for me, is in many ways fragile, elusive, variable, and has no material essence, real nature, or form. I thus chose to work with aesthetic and spiritual phenomena.

Visible blindness in the urban world society's relation to light now and then
Pata, Václav ; Sedlák, Michal (advisor) ; Gajdošíková, Pavla (referee)
The diploma thesis is focused on city in time and age of artificial lighting. It takes the issue of light pollution as its starting point. Elementary sources and consequences of over- lighting are used as a base for the Forgotten Dark worksheets. The sheets were created in collaboration with Veřejný sál Hraničár (Public Hall Hraničář) as an educational material for the gallery cycle Light. Together with the sheets, a need to widen my knowledge and apply it to a specific situation arose. I picked Obchodní dům Prior and Kulturní středisko Corso (Shopping Mall Prior and Culture Center Corso) in the neighborhood of Krásné Březno for that purpose. The pick of the place directed the development of the themes of the theoretical part of the thesis. The middle part of the thesis is trying to show contemporary city from two essential angles. Firstly, I tried to answer the question about sources of the shape contemporary city has taken upon itself. The rest is focused on building public spaces in regard to their nighttime flow. The final chapter is exploring the object of Corso. At first It is trying to take a look at the context of the city part of Krásné Březno, then it is taking a look at the city part in context of Ústí nad Labem. The gathered information is used for a presentation of possible future of...

Design of optoelectronic sensor for biological tissues
Balík, Zdeněk ; Bartlová, Milada (referee) ; Tománek, Pavel (advisor)
Biological tissues are optically inhomogeneous and absorbent materials. They are comprised of various structures such as cells, cell organelles, and various fiber structures. Due to these structures leads to different interactions with the light and phenomena such as absorption, scattering and polarization of light. Different ultrasonic, electromagnetic, electrical and optical methods are used for meat ageing detection. Muscles are turbid anisotropic media, they exhibit changes in electrical and optical properties according to the direction of the electrical and optical fields in the sample. The diploma work assesses the feasibility of impedance measurements for meat ageing detection and their comparison with optical measurement of scattered polarized light. Two different sample were used: pork chop slices and chicken breasts were used for their relative homogeneity. The electrical method is a promising method due to the possibility of getting much information and realizing cheap and fast enough measurement systems. The proposed optical method allows measure the rotation of polarization plane with meat ageing in the range of 95 degrees within considered period. Through the first promising results obtained in this thesis, a further work has to be provided to determine closer relationship between optical scattering characteristics, electrical anisotropy in ageing-related tissue structural properties.
