Scanning Probe Microscopy: Measuring on Hard Surfaces
Matějka, Milan ; Urbánek, Michal ; Kolařík, Vladimír
During a measurement by scanning probe microscopy (SPM) an image artifacts can appear in a measurement data. The source of image artifacts during an SPM measurement could be in parts of the SPM tool: mechanical system, piezoelectric crystal, scanner electronic. However, the main source of image artifact is the probe tip geometry and properties of the sample. For example, probe wearing, which occurs during the contact measurement on a sample with a hard surface, could result in heavy probe shape change, causing probe-related image artifacts. Measurement could appear problematic on a sample with periodical relief structure (e.g. gratings with sub 10 μm periodicity) prepared in hard materials (e.g. silicon), when the structure height is greater than about 500 nm. In this case, probe can easily get struck during the scanning, on the hard surface as well as at the high aspect ratio relief structure, causing image artifact thus reducing measurement quality.

SPM Nanoscratching in the Sub 100 nm Resolution
Urbánek, Michal ; Kolařík, Vladimír ; Matějka, Milan
Scanning probe microscopy (SPM) is tool basically used for surface characterization. Besides that, it offers several lithographic methods (e.g. nanoscratching) to prepare structures in the sub 100 nm resolution. The nanoscratching using SPM offers a method for patterning of surface with a very high resolution based on near field interaction. By this method some tiny marks or taggants could be prepared. Therefore we used the SPM nanoscratching for preparation of nanostructures in thin soft polymer films by various tips. Nanoscratching regime of SPM is possible to operate in contact and close contact modes. In the contact mode we prepared an array of stamps with a variable size, where dimensions and depth dependency on number of pixels were inspected. For writing of these structures we used polymer films with different softness (e.g. PMMA, SU-8) and various values of setpoint, which are responsible for structures deepness.

THE LIFE AND WORKS OF GIUSEPPE VERDI FOCUSSING ON THE OPERA DON CARLOS
Urbánek, Miroslav ; Podskalský, Miloslav (advisor) ; Podskalský, Miloslav (advisor) ; Tuček, René (referee)
Giuseppe Verdi is amongst one of the greatest opera composers of the nineteenth century. Despite his life's tragic fates he was full of energy which transpired into his operas. His work stems from a strong Italian operatic tradition and culminated to became the peak of Itatian of the ninteenth century. His beginnings were still in an tradition we he left to create a new. He began to write through composed, large scale works with dramatic content to match. Thw works of Berlioz and Wagner had a large influence onVerdi but even as such he did not allow his music to be taken over stylisticly but rather held to his own.The greates treaures in Verdi's music are the beautiful melodic lines of witch he was a master the ever creative rhythmic motives. He uses speaks to the listner through its simple and clear nature. Verdi lifted Itatian opera to a new and higher level. He intentionally chose materials and subject matter that were close to his individual creative person and didn't entertain subjects which were not. Dispite his inovativness he strongly believed that to the leave the Italian operatic tradition was amongst one of the greatest dangers. His operas today belong amongst some of the most played of operas ever written.

Financial Crisis and Business Cycle - the analysis of rescue package against crisis in the Czech Republic
Urbánek, Martin ; Ševčíková, Michaela (advisor) ; Loužek, Marek (referee)
The main goal of my bachelor thesis is to analyze and compare steps against crisis, which were proposed in the Czech Republic to alleviate the effects of the Financial Crisis there. I focus mainly on the National anti-crisis plan and its possible alternatives. The whole analysis is based on available empirical dates. In a theoretical part I deal with current financial and economic crisis from the point of view of economic theory. I focus mainly on the theory of Financial Crisis and the theory of the Business Cycle. In the second part I deal with indicators of current Financial Crisis and I describe the current state of world economy as a result of financial and economic crisis. Then I analyze rescue packages and I focus on some individual steps to mitigate negative impacts of the Financial Crisis in the Czech Republic. Then I describe some potential impacts of those steps to the Czech economy. At last, but not at least I focus on steps, which are the most effective ones from my point of view and I describe their positive effects on the Czech economy.
