Design of the telescope spectrograph for distant object analysis
Drobil, Tomáš ; Pořízka, Pavel (referee) ; Novotný, Jan (advisor)
Meteor spectra obtained from orbit include many spectral lines in the ultraviolet region, which is mostly absorbed by the atmosphere and thus cannot be observed from ground stations. This bachelor thesis focuses on the design of a spectrograph, placed in a 2U CubeSat, suitable for meteor observation and its spectral analysis in the range from the ultraviolet to near-infrared region. The design includes choice of a suitable camera. Based on the required parameters, several designs have been created, and the process is summarized in the last chapter. The research study of telescopes combined with spectrometers used for meteor observations is also included.

Popularization of science in Czech audiovisual media with focus on astronautics
Vopršal, Lukáš ; Jirák, Jan (advisor) ; Halada, Jan (referee)
This thesis deals with the topic of processing and popularization of science, namely the field of cosmonautics within the context of the Czech audiovisual media. The first aim of the thesis is to critically analyze the content of selected episodes broadcasted on a science-popular program within the course of the years of 2021-2022. The second aim is to evaluate the use of popularization elements within the selected episodes through an application of suitable comparative methods. The dissertation is divided into a theoretical and a practical part. In the theoretical part of the work, a research was conducted based on Czech and foreign professional literature, with the aim of mapping and describing different approaches to the popularization of science in the media. This has been done by defining the terms science, mass media, scientific journalism and popularization of science within this context. An extensive part of the research is organized in a chronological fashion, encompassing the development and evolution of Czech scientific journalism, with its beginnings in the second half of the 19th century to the present day. This trajectory is analyzed in detail using the examples of two renowned science-popular programs called "Meteor" and "Okna vesmíru dokořán". In the practical part, it has been...

METEOR - perennial star beetwen radio programme
Jaklová, Anna ; Beneš, Zdeněk (advisor) ; Šmíd, Marek (referee)
In this diploma thesis I focus on the popular science program for children and youth Meteor, which has been regularly broadcast on radio since 1962. In the opening chapter I am introducing the early years of radiotelephony on our territory - how it gets from the microphone to the telephone handset in the Kbelský tent to the obligatory listening to schools. I also explain the purpose of radio and its effort to spread awareness. For the sake of full understanding it was necessary to state the context of the situation of the 60s to which the Meteor was born. Subsequently, I focus on the history of Meteor, who recently celebrated his 55th birthday, his founders, the main features of the show. In the last part I summarize the current situation and present an interview with the current head of Meteor Petr Sobotka.

Analysis and Suppression of Noise in Astronomical Video
Švihlík, J. ; Fliegel, K. ; Koten, Pavel ; Jerhotova, E. ; Vítek, S. ; Páta, P.
This paper is devoted to noise suppression in systems for double station observation of meteors, nowadays known as MAIA (Meteor Automatic Imager and Analyzer). The noise analysis based on acquisition of testing video sequences at different lighting conditions and their statistical evaluation were described in our previous paper The measurement showed that the type of noise generated by the system is signal-independent in a certain illumination range. The noise and image models in the wavelet domain are based on the Generalized Laplacian Model (GLM) and it is the most convenient to estimate the model parameters using the moment method. Furthermore, the noise component may be modeled by the GLM also in the space domain. Overall, we verified that the GLM allows for modeling various types of probability density functions. In the final section of this paper, the performance of the proposed advanced de noising algorithm is verified on the real data, which were acquired in the Astronomical Institute.

Web Application Development on Meteor Platform
Hlaváček, Josef ; Buchalcevová, Alena (advisor) ; Mittner, Jan (referee)
The thesis describes the Meteor Platform and the process of real-time web application design and development. The objective is to provide information covering the technology behind real-time web applications and to describe the Meteor application design and development process utilizing the MMSP methodology. First part of the thesis defines what a real-time web application is and describes Node.js platform and javascript frameworks Mojito, Derby and Meteor. The second part deals with Meteor application design and development process and provides information about used architecture and components. The last chapter provides recommendation on Meteor application development and suitability of the framework for various types of applications, as well as utilization of the MMSP methodology for Meteor application development. The main output and benefit of the thesis is the real-time web application Chute Achiever, which can be used for educational purposes. This thesis is the first academic work about Meteor platform published at the University of Economics.
