Laser projector for advertisement
Krist, Jakub ; Bajer, Arnošt (referee) ; Pavlík, Michal (advisor)
The scope of this work is to design equipment capable of using a single laser source project programmed image or text. Introduction is a summary outlining the basic principles of image projection in laser imaging. This thesis describes the design of a laser projector that is using microcontroller AT MEGA16 together with auxiliary electronics and rotating ring, able to draw the desktop system bitmap graphics.
Using generalized functions in continuum mechanics
Procházka, Petr ; Netuka, Horymír (referee) ; Pochylý, František (advisor)
Tato práce se zabývá využitím distribucí neboli zobecněných funkcí k řešení nestacionárních okrajových problémů v mechanice kontinua. Nejprve je zavedena teorie distribucí a jejich definice jako spojitých lineárních funkcionálů na prostoru testovacích funkcí. Druhá část teoretické kapitoly představuje Laplaceovu integrální transformaci. Následující kapitola se věnuje řešení průhybu nosníků pod vlivem nespojitého časově proměnlivého zatížení. Jejím výsledkem je vytvoření obecného modelu řešení průhybových čar nosníků vužitím distribucí. Poslední kapitola se zabývá řešením nestacionárního proudění v trubicích spojených hydraulickými prvky.
Overview of application of singularity functions in education of the beam deformation characteriscs.
Sejbal, Štěpán ; Profant, Tomáš (referee) ; Horníková, Jana (advisor)
The purpose of this work is gathering and comparing of literary foundations to implementing of singular functions and their applications at foreign universities and in world literature.
Electron Beam Control and Diagnostics for Advanced Technologies
Zobač, Martin ; Kolařík, Vladimír (referee) ; Průša, Stanislav (referee) ; Lencová, Bohumila (advisor)
The thesis deals with problems of control and diagnostics of electron beam technological devices which use electron beam for localised intensive heating of a material. A brief description of the electron beam welder MEBW-60/2 is included; the author has participated on its development and implementation. Main topics are the analysis of deflection system properties and the measurement of current distribution of the beam (so-called beam profiles). Geometrical aberrations, hysteresis, stability and dynamics of a single-stage magnetic x-y deflection system are described. Suitable measurement procedures and correction methods are introduced. Methods of transverse and longitudinal beam profile acquisition is presented using successive sampling of the local current density of the beam by a modified Faraday cup. The data processing and evaluation of characteristic beam parameters are shown. The presented methods were verified by fourteen experiments using the electron beam welder. The methods have proven to be useful in practical evaluation of the device properties.
Kamera crane
Nádvorník, Jan ; Hutař, Pavel (referee) ; Brandejs, Jan (advisor)
This thesis deals with product design rotating camera crane with variable length telescopic arm. Proposed maximum arm length is 6 [m] with a maximum weight capacity of the camera 8 [kg]. The work deals with the various structural units associated mainly with the issue of the telescopic arm. In individual sections detail the construction of the camera head developed deformation and stress analysis of a telescopic jib.
Utilization of generalized functions (Dirac) in continuum mechanics
Procházka, Petr ; Netuka, Horymír (referee) ; Pochylý, František (advisor)
The aim of this thesis is utilization of generalized functions. Firstly, basis of generalized functions theory and operations on their space are introduced. Secondly, examples and general model for calculating deflection lines of discontinuously loaded beams using distributions are shown. Towards the end, pressure loss in real incompressible fluid flowing in straight pipe system with hydrailic features is calculated.
