Transmission of human body's movement into sound using sensors
Rataj, Jakub ; RATAJ, Michal (advisor) ; TROJAN, Jan (referee)
This work treats about the permeation of two different compositional approaches (real time technologie and instrumental composition) in proper piece of art - music and dance performance The Art of Manipulation. First I treat about the development of interactive motion sensing systems in the last fifty years and further I describe to different possibilities of their categorisation. In the next part I describe the performance The Art of Manipulation in terms of its dramaturgy and musical content. Further I deal with compositional methods that I used in the instrumental and electroacoustic musical plane and concurrently I analyze their relationship. In the end I describe the architecture and function of the virtual instrument used for real time sound recording and processing.

Střihové napětí na stěně pod velkou bublinou stoupající v nakloněném plochém kanále
Tihon, Jaroslav ; Pěnkavová, Věra ; Vejražka, Jiří
The motion of single air bubbles in an inclined flat water channel is investigated experimentally. The electrodiffusion technique of near-wall flow diagnostics is applied to measure the wall shear stress distribution under large bubbles rising along the upper channel wall. The electrodiffusion measurements are synchronized with the visual observation of bubble movement done by a high-speed camera. The analysis of video records provides information on the bubble shape and terminal velocity. The experiments are carried out for three different channel heights and cover a wide range of channel inclination angles (from horizontal to vertical position). The experimental results on bubble motion characteristics obtained in stagnant and upward-flowing liquid arrangements are confronted with the recent predictions and scaling provided by theoretical models.

Motion in Faulkner: An Analysis of Movement in The Sound and the Fury
Hesová, Petra ; Ulmanová, Hana (advisor) ; Matthews, John Thomas (referee)
The Gothic is an extremely viable mode in the history of American literature. As a genre concerned principally with distortions and aberrations, it provides a platform for writers to voice their concerns about periods of transformation and destabilized boundaries. William Faulkner, one of the leading authors of the American South, frequently employs the Gothic mode in his portrayals of the South as a traumatized region trying to cope with the echoes of the Civil War and with the disintegration of old aristocratic values, which manifests itself in the decay of institutions (such as the family) as well as a collapse of individual minds. This emphasis on the human psyche is evident especially in the novel The Sound and the Fury, whose main characters and narrators are representatives of the various extremities of the human psyche (severe mental retardation, suicidal tendencies, schizophrenia and paranoia). Faulkner's use of the Gothic mode is rather unorthodox and innovative, employing inversions and parody which can be appropriately demonstrated by the category of motion and his use of the traditional Gothic devices and character types. The traditional motion patterns - flight and pursuit, quest and purposeless wandering - that are originally connected predominantly with only one Gothic type (the...

Motion control during hanged object transportation
Richter, Jan ; Davidová, Olga (referee) ; Němec, Zdeněk (advisor)
The Diploma Thesis focuses on examination of most suitable optionsof movement regulation of pendent object from the perspective of various requirements on the course of the process as such. The environment of Matlab-Simulink was used for the analysis. The first part of the Thesis deals with the creation of the model of the whole system and creation of additional models of systems with similar, highly oscillating behaviour. The central part of the Thesis focuses on the design of suitable methods of movement regulation during translocation of the pendent object, which is tested on a simple model of travelling monkey. Four approaches to the problem solving were chosen: simple regulation by PID regulator, branched regulation, state regulation and predicative regulation. All solving options are being analysed and optimised and their results mutually compared according to requirements defined, such as: speed of the process, fluency of the movement, small pose overshoot or small angle of rope deflection.

Slowly rotating sources around static black holes
Čížek, Pavel ; Semerák, Oldřich (advisor) ; Ledvinka, Tomáš (referee)
In this thesis we study the possibility of perturbative solution of the Einstein equations in the case of stationary and axially symmetric metric. The method is motivated by the pursuit of describing the astrophysically important system of a black hole surrounded by a thin disc or a ring. A Schwarzschild black hole is thus considered as a central source, with a light and/or slowly rotating disc around. We show that the metric can be found in terms of perturbative expansions in relative disc mass or in inverted distance from the hole, and point out where problems occur. The approach can be applied to a disc "given in advance" as well as in the "self-consistent" case when the disc elements orbit on circular geodesics in the desired total eld. It can also be generalised to the discs composed of more dust components.

Napěťová analýza lidských hlasivek
Vampola, T. ; Horáček, Jaromír
A three-dimensional (3D) finite element (FE) fully parametric model of the human larynx was developed and used for numerical simulation of stresses during vibrating vocal folds the collisions. The complex model consists of the vocal folds, arytenoids, thyroid and cricoid cartilages. The vocal fold tissue is modelled as a three layered orthotropic material. The results of numerical simulation of the vocal folds oscillations excited by a prescribed intraglottal aerodynamic pressure are presented. The FE contact elements are used modelling the vocal folds collisions and the principal and shear stresses are computed in time domain on the surface and inside the vocal fold tissue. The results show significant dynamic stresses in all there directions and comparable maxima of Von Mises stresses were obtained for closed and open phases of the vocal folds motion.

Zviditelnění nestacionárního proudění kolem vibrujícího profilu: Experimentální uspořádání a předběžné testy
Vlček, Václav ; Horáček, Jaromír ; Luxa, Martin ; Veselý, Jan ; Bula, Vítězslav
The contribution presents the designed aeroelastic model, experimental set-up and preliminary tests of optical measurements of flow field around a vibrating NACA 0017 profile elastically supported in the measurement section of the wind tunnel. The profile can vibrate with two degrees of freedom for translation and rotation. The interferometry method combined with the high speed filming was used for flow visualization of in different phases of the profile motion. The measurements were performed in a subsonic wind tunnel above the airflow velocity for loss of the system stability by flutter, thus the vibration amplitudes were relatively large up to about 7 mm for vertical translation and 16.5 degrees for angle of rotation around the elastic axis. The 52 images of the flow field were recorded during one oscillation period of the profile from which the pressure and velocity can be evaluated in the given time instants.
