Meteor Shower Fireballs
Shrbený, Lukáš ; Spurný, Pavel (advisor) ; Svoreň, Ján (referee) ; Bland, Philip A. (referee)
Centimeter-sized meteoroids cause bright meteors, called meteoric fireballs, during their encounter with the Earth's atmosphere. These fireballs can be observed by all-sky photographic methods. In this thesis, bright meteors belonging to major meteor streams are studied. All presented fireballs were recorded during last few years by all-sky photographic cameras from the Czech part of the European Fireball Network, Spain (Leonids 1999 campaign), and from the Australian Desert Network. Physical properties in terms of different methods (end height criterion, beginning heights, apparent ablation coefficient, fragmentation, dynamic pressure at the height of fragmentation or terminal flare), very detailed light curves (periodic changes of brightness, afterglow, shortlived flares, profiles) and heliocentric orbits are studied by individual showers. Studied meteor showers are Orionids, Geminids, _-Capricornids, Southern -Aquariids, Leonids and Perseids and a comparison of their main properties was performed. Also comparison with meteorite dropping fireballs was performed.
Selection and implementation of the information system for a project construction company
Spurný, Pavel ; Ulman, Miloš (advisor) ; Martin, Martin (referee)
This thesis deals with the issue of information systems targeted at Small and medium-sized enterprises (SMEs). The theoretical part defines basic terminology and creates thereby the theoretical base of the issue of a company´s information systems (IS). Then an analysis of the influence of implementation of information technologies into SMEs is carried out determining the development of the region. The practical part of the thesis is based on a case study dealing with the implementation of the information system QI for a medium-sized project construction company. The case study captures the whole process consisting of the selection of the product, pre-instalment analysis, implementation of the IS, training of the users leading to the system fully operating live. Built on that is then the following economic calculation of the implementation of the IS. The portability of the used solution is then assessed and the resulting outcome of the IS for the company is then evaluated. Drawbacks of the whole process are identified and their solutions are suggested.
Dynamics and fragmentations of meteoroids during their flight in the atmosphere
Kalenda, Pavel ; Borovička, Jiří ; Spurný, Pavel
The dynamic fragmentation of meteoroids during their flight in the atmosphere is described. The examples of very weak meteoroids, which easy fragments, up to strong meteoroids, which produce the explosive fragmentation, are described.
