This diploma thesis deals with creation of several random number generators. The data from these prototypes are then compared according to various aspects and statistical methods. The reader is familiar with the basic concepts, the existing random number generators and the technologies used.

Random number generation can be based on physical events with probabilistic character, or on algorithms that use complex or one-way functions, alternatively on both of these approaches. A magnetic vortex is a basic state of magnetization that forms in magnetic micro- and nanostructures of an appropriate shape, dimensions and material. Quantities of the magnetic vortex form randomly if ambient conditions are chosen eligibly. A concept of a true random number generator using a random switching of states of the magnetic vortex is presented in this thesis. This concept is realized and random numbers were experimentally generated and numbers were statistically analysed.

The diploma theses deals with the concept leadership, the concept learning organisation and their reciprocel relationship, specificaly about function leadership in the learning organisation. The theses defines, observes and researches these two phenomenas in the segment of education, specificaly in schools related to programm "The leader in me" both in the Czech Republic and abroad - the Netherlands. Leadership mentioned in this work represent the 7 habits of highly effective people by Stephen R. Covey as the main tool. The theses concerns the teachers' profesional development and their general personal characteristics, in a view of regarding development. The goal of the work is to summary of opinions related to the Covey 7 habits of highly effective people as leadership tool. Based on the summary the theses defines role of leadership in the learning organisation in the area of school and describes reciprocal relationships leadership and learning organisation and the area of professional development in the behaviour of teachers. Furthevemore, the these evaluates the importance in relationships from in accordance with effectivity and success of the learning organisation in the school area. The theoretical part of the theses defines the main concepts of work - leadership, learning organisation,...
