Online Quizzes in Information System
 Sláma, Pavel ; Skokanová, Jana (referee) ; Lampa, Petr (advisor)
This thesis is trying to find its way in extensive area of relatively new problems of E-learning. E-learning has come together with fast advancement of the Internet trying to make education more comfortable and faster and at the same time trying to lower its dependency on the human resources. A lot of a development of the online tests is still needed. However, it is important to make clear the rules of the "game" and to press for their integration. The first goal to achieve the full-value system which would be able to substitute the conventional methods of education is to find out and solve the issues of testing in general, to analyze the requirements and to create data format for the data portability, which is required because of the mutual communication between different systems. On these bases it is possible to design the database scheme and then the complete system.

Parametry bílých LED při dodržení provozních podmínek
 Pavelka, Tomáš ; Doležal, Petr ; Sláma, Pavel
Paper brings knowledge from measurement on white power LEDs for general lighting applications considering operational conditions that affect quantitative and qualitative light parameters of LEDs as well as basic electrical parameters. These data are necessary for correct design of luminaire and even for basic understanding of LED behaviour in real applications, so it can be used for creation of proper model of LED parameters degradation. Measuring of LED parameter changes is based on spectroradiometry to provide information not only about luminous flux change but also about qualitative parameters changes such as chromaticity temperature and colour rendering index.
