Flight Simulator Based on Jason Multi-Agent System
Punčochářová, Pavlína ; Zbořil, František (referee) ; Samek, Jan (advisor)
The aim of this work is to create a 2D flight simulator using Jason multi-agent system and AgentSpeak language. In this simulator, the aircrafts will be represented by agents and their behavior will be described by plans implemented in AgentSpeak language. Agents will use these plans to demonstrate different types of behavior such as detection and collision avoidance, the taking of a position or persecution. The final application consists of two parts - the simulation module and the user interface. Simulation module is the core of simulator and it is created in the Jason system. The user interface provides the possibility to control simulations and creating user simulation models.

Autonomous Management of Intelligent Home
Punčochářová, Pavlína ; Viktorin, Jan (referee) ; Korček, Pavol (advisor)
Currently, the topic of smart home is not new and there are many solutions for this problem on a market. Emphasis is placed on miniaturization of the individual elements of an intelligent system and control logic of the system as a whole. This is associated with requirement for ensuring management capabilities of the system in case of failure of the connection between some of the functional elements and the control member. This work deals with design and implementation of modifications in intelligent home gateway in an existing BeeeOn project to ensure its autonomy even in case of loss of internet connection. The problem of loss of ability to manage the household is solved by adding the possibility to establish direct communication with the gateway and the introduce automation ability into gates to control household without the participation of the controlling member. This extension brings autonomy into the system and allows user to have the household under control even in case of loss of internet connection. It leads to increase system security and quality of service in general.

Numerical simulation of unsteady low-Mach number viscous flow in a channel
Punčochářová, P. ; Kozel, Karel ; Horáček, Jaromír ; Fürst, J.
This study deals with a numerical solution of a 2D unsteady flow of a compressible viscous fluid in a channel for low inlet airflow velocity. The unsteadiness of the flow is caused by a prescribed periodic motion of a part of the channel wall with large amplitudes, nearly closing the channel during oscillations. The channel is a simplified model of the glottal space in the human vocal and the flow can represent a model of airflow coming from the trachea, through the glottal region with periodically vibrating vocal folds to the human vocal tract. The flow is described by a system of Navier-Stokes equations for laminar flows. The numerical solution is implemented using a grid of quadrilateral cells. Due the motion of the grid, the basic equations are considered in the Arbitrary Lagrangian-Eulerian form. Numerical results are presented for Mach number 0,012m, Reynolds number 5000 and vibration frequency 100 Hz.

Numerická simulace stlačitelného proudění s nízkým Machovým číslem skrz oscilující štěrbinu
Punčochářová, Petra ; Fürst, J. ; Kozel, Karel ; Horáček, Jaromír
The work deals with the numerical solution of 2D unsteady compressible viscous flows in a symmetric channel for a low inlet airflow velocity. The unsteadiness of the flow is caused by a prescribed periodic motion of a part of the channel wall with large amplitudes, nearly closing the channel during the oscillations. The flow in the channel can represent a simplified model of airflow coming from the trachea, through the glottal region with periodically vibratin vocal folds to the human vocal tract. The numerical solution is realized by finite volume method and the explicit predictor-corrector MacCormack scheme with Jameson artificial viscosity using a grid of quadrilateral cells. The moved grid of quadrilateral cells is considered in the form of conservation laws using Arbitrary Lagrangian-Eulerian method.

Numerické řešení stacionárního a nestacionárního stlačitelného viskozního proudění v kanále
Punčochářová, P. ; Kozel, Karel ; Horáček, Jaromír ; Fürst, J.
This study deals with numerical solution of 2D unsteady flow of compressible viscous fluid in channel for a low inlet airflow velocity. The unsteadiness of the flow is caused by a prescribed periodic motion of a part of the channel wall with large amplitudes. The channel is harmonically opening and nearly closing. When closing the airlow velocity is becoming much higher in the narrowest part of the airways, where also the viscous forces play important role. Therefore for a correct modelling of a real flow the compressible, viscous and unsteady fluid-flow model decribed by Navire-Stokes equations should be considered. The authors present the simulations of the flow field by the expecially developed program.

Numerické řešení nestacionárního proudění stlačitelné viskozní tekutiny v kanále
Punčochářová, Petra ; Kozel, Karel ; Fürst, J. ; Horáček, Jaromír
This work deals with numerical solutin of viscous laminar flows in a channel with time-changing wall. MacCormack scheme and Jameson artificial viscosity are used for numerical solution in the form of finite volume method with grid of quadrilateral cells. Mathematical model is unsteady system of 2D laminar Navier-Stokes equations. Unsteady behavior is caused by time dependent-boundary of lower. The channel represents a simple case of vocal tract. an unsteady domain is presented using Arbitrary Lagrangian-Eulerian method. In the work several numerical results of flows in two different channels are presented.

Numerické modelování nestacionárního proudění viskozní tekutiny ve 2D kanále pro nízká Machova čísla
Punčochářová, Petra ; Kozel, Karel ; Fürst, J. ; Horáček, Jaromír
The work presents an unsteady viscous flow for low upstream Mach number (M =0.012) in a 2D channel. Unsteady flow is caused by a moving part of the channel wall as a given function of time. The problem is described by the system of Navier-Stokes equations for compressible leminar flows. It is numerically solved by the explicit central finite volume version of MacCormack scheme on a grid of quadrilateral cells. Moved grid of quadrilateral cells is considered in the form of conservation laws using Arbitrary Lagrangian-Eulerian method. Physically the flow in the symmetrical channel can present some very simple model of flow in a human vocal tract. The aim is to compare two different cases of this problem of the flowfield.
