	Photovoltaic Battery Charger with Sun Tracking Knob, Martin ; Kufa, Jan This paper describes the design of a photovoltaicbattery charger. The charger can track the sun and tilt the panelin azimuth and elevation. The device includes an Maximum PowerPoint Tracking (MPPT) regulator to maximise the energy from thephotovoltaic panel. This photovoltaic charger is designed for Liionbatteries and is equipped with appropriate battery protection.The system is battery-powered and therefore energy selfsufficient.Another purpose of the device is to measure accuratedata for further processing. It will measure the energyconsumption required for its operation and the energy producedby the photovoltaic panel. The device communicates wirelessly viaWi-Fi and sends the measured data to the Thingspeak server. Detailed record
	Photovoltaic battery charger with sun tracking Knob, Martin ; Frýza, Tomáš (referee) ; Kufa, Jan (advisor) This thesis describes the design of photovoltaic battery charger. The charger can tracking the Sun and tilt the panel in azimuth and elevation. The device includes an MPPT regulator to optimise the energy produced by the photovoltaic cell from the Sun. This photovoltaic charger is designed to charge Li-Ion batteries and includes appropriate charging and protection circuits. The charger is energy self-sufficient, which means that it does not need an additional power source. Another purpose of this device is to measure electrical quantities. The device sends the measured data wirelessly via Wifi. Detailed record

	Experimentální vyšetřování proudění v okolí vibrujícího křidélka pomocí metody TR-PIV Uruba, Václav ; Knob, Martin ; Vlček, Václav ; Luxa, Martin ; Lukáč, Jan ; Dvořák, Rudolf Results from experiments on flow around vibrating wing in high-speed subsonic flow are presented. The Time Resolved PIV technique was used to follow dynamical behavior of both the elastically mounted wing and the flow-field behind the wing. The applicability of the chosen method for a given case was proved positively. Detailed record
	PIV měření proudových polí v modelu lidského vokálního traktu Horáček, Jaromír ; Šidlof, Petr ; Uruba, Václav ; Veselý, Jan ; Radolf, Vojtěch ; Bula, Vítězslav ; Knob, Martin The contribution describes an especially developed complex physical model of the voice production that consists of simplified models of the trachea, the self-oscillating vocal folds and the vocal tract with acoustical spaces that correspond to the vowel /a:/. The presented measurement set-up enables to use the PIV method for visualization of the airflow-pattern and synchronous vocal fold vibration visualization, acoustic and pressure measurements. Some preliminary results are presented as well. Detailed record
	Dynamics of a boundary layer separation Uruba, Václav ; Knob, Martin Dynamical behavior of a boundary layer separation is studied using experimental approach. The dynamical nature of the phenomenon is demonstrated on a simple case of a boundary layer in adverse pressure gradient. The Time-Resolved PIV technique was utilized to study instantaneous structure of the separation region and its time development. Distinctive coherent structures and their dynamical behavior were identified using the POD and BOD methods. Detailed record
	Aplikace ortogonálních dekompozičních metod Uruba, Václav ; Knob, Martin Orthogonal decomposition techniques are introduced with respect to application to time-resolved PIV data. Several modifications of the techniques are taken into account, particularly the Proper Orthogonal Decomposition in continuous and snapshot variants for space analysis only as well as the Bi-Orthogonal Decomposition to be used for joint space-time analysis.

	Nestacionární charakteristiky rovinného paprsku, vstřikovaného do korátkové kavity Knob, Martin ; Uruba, Václav ; Antoš, Pavel ; Popelka, Lukáš ; Šafařík, Pavel ; Adamec, J. In the article, the results of the biorthogonal decomposition of a 2D TR PIV data of a jet impinging into a trough cavity, are presented. The obtained spatiotemporal structure is shown and its physical meaning is clearly explained. Detailed record
	Nestacionární vírová struktura vyvolaná parpskem tekutiny vstřikovaným do korýtkové kavity Knob, Martin ; Uruba, Václav In the contribution, the results of vortex identification in an unsteady TR PIV data of a cavity subject to a jet impingement are presented. The main phenomena, such as vortex loop are shown and their relation with local pressure minima is described. Detailed record
	Krátký přehled metod identifikace vírů s ohledem na data naměřená 2D PIV Knob, Martin ; Uruba, Václav A brief survey of four basic vortex identification methods, namely the Q- criterion, the l2 method, the G2 method and the Complex eigenvalue method, is given in this contribution. All the methods are investigated on an artificial flow- field as well as an unsteady signal, obtained by the TR PIV system. The results of all the methods are evaluated and compared. Detailed record
