Web-Based Demonstration of Linear Filters Design
Pospíšil, Ondřej ; Černocký, Jan (referee) ; Novotný, Ondřej (advisor)
The aim of this work is to create a demonstration application focused on the design of digital filters. In the first chapters we outline the theory of digital filtration and design of digital filters. Then we summarize and evaluate the existing solutions. The following chapters describe the design and implementation of the actual application.

Residential Complex in Brno - Komín
Novotný, Ondřej ; Františák, Luboš (referee) ; Nový, Vítězslav (advisor)
Residential complex is located in district Brno-Komín surrounded by garden colonies among Pastviny and Houškova streets. Local structures are characterized by significant diversity, where the old village houses, block of flats from 80s, and detached houses from 21st century are represented. The design is not trying to enter local structures inappropriately. The major afford is to combine high density and low-rise housing with quality of public space. We are able to understand whole area as the border between the city structures and countryside, that is soften by designed objects. Complex is formed by three main buildings, which also confront the idea of baugruppe. Houses combine characteristics of block of flats and detached houses.

Design of assist robot
Novotný, Ondřej ; Látal, Roman (referee) ; Kučera, Petr (advisor)
The aim of the Bachelor thesis is design of frame and lifting mechanism of assist robot called „Bob“. The thesis consist of several construction design of mechanism and gears, final solution control and creating of prototype. For the materiál of frame construction was chosen the aluminium because of its hardness and weight. The chassis of robot is 3-wheeled construction unable passing through threshold. The motor for robot drive was chosen DC motor with 500 rpm and torque 600 Nmm, which is placed inside of front wheels. For the lifting mechanism was chosen the motion screw with trapezoidal screw-thread Tr 10x3 made by DIN 103 from C15 steel. Another part of the thesis was create of the prototype for testing whole mechanisms and gears.

Adaptation of Speaker Recognition Systems
Novotný, Ondřej ; Pešán, Jan (referee) ; Plchot, Oldřich (advisor)
In this paper, we propose techniques for adaptation of speaker recognition systems. The aim of this work is to create adaptation for Probabilistic Linear Discriminant Analysis. Special attention is given to unsupervised adaptation. Our test shows appropriate clustering techniques for speaker estimation of the identity and estimation of the number of speakers in adaptation dataset. For the test, we are using NIST and Switchboard corpora.

Mobile Applications for Real-Time Noise Removal
Siladi, František ; Skácel, Miroslav (referee) ; Novotný, Ondřej (advisor)
The goal of this bachelor's thesis is to create a mobile application which will remove the noise from speech in real time. The first chapter describes the theory related to signal processing and described filters for denoising. The following chapter summarizes existing solutions. The third chapter contains my own design and implementation. At the end of this thesis is the evaluation of the application and evaluation from users.

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.

ResPublica/Civitas Socialis - Vision Křídla
Novotný, Ondřej ; Hudec, Mojmír (referee) ; Nový, Vítězslav (advisor)
The goal of diploma thesis is urbanism and architecture study of village central part, reconstruction of municipal house and new house of fire department and community center in Kridla. The village itself is located six kilometres far away from Nove Mesto na Morave in Bohemian-Moravian highlands. The design is not trying to enter local structures inappropriately. The major affort is to combine different functions and activities with quality of public space and respect of countryside area. One of the goals is also to provoke discussion about vision for the next 30 years among inhabitants of Kridla.

The Experience of Nonbinary Individuals with Self-Presentation and Gender Expression (from a Phenomenological Perspective)
Novotný, Ondřej ; Smetáčková, Irena (advisor) ; Macháčková, Marcela (referee)
This bachelor's thesis explores lived experiences of individuals who identify as non-binary, both in personal spheres and social interactions. It defines the concept of gender and examines related concepts such as its development, roles, stereotypes, and its socially constructed nature, as well as its interaction with social and personal identity. It briefly touches on androgyny and gender-aschematicity and their potential positive impact on society through reducing the salience of gender stereotypes, by promoting more flexible notions of gender. In the empirical section, the thesis analyses the narratives of four non- binary informants (obtained through semi-structured interviews) using interpretive phenomenological analysis. It specifically focuses on self-presentation and gender expression in relation to authenticity, studying the interaction between the self and the social environment. The thesis highlights the variability in experiences among these four individuals and summarizes their experiences into emergent themes and subthemes. Through description and interpretation, it seeks to elucidate and explain the individual experiences of the informants. Various common themes arise, such as: (1) the relationship between pressure exerted on the individual and the perceived need to challenge...

Experimental validation of active flow concept on wing section
Novotný, Ondřej ; Zima, Martin (referee) ; Popela, Robert (advisor)
The aim of this diploma thesis is experimental validation of active flow concept on the wing section. This concept could be replacement of commonly used high-lift devices. In the be-ginning of the thesis, a different high-lift devices and other experiments of active flow con-trol are described. Practical part of the thesis describes a preliminery of the measurment, such as preparing wind tunnel section, design of the rotary device and models of the wing section. Next chapter describes measuring of the wing section without active flow control and wing section with active flow control. In the end of the thesis the measurement was compared with CFD analysis.
