INFLUENCE OF LASER CUTTING AND PUNCHING ON MAGNETIC PROPERTIES\nOF ELECTRICAL STEEL M470-50A
Bulín, Tomáš ; Švábenská, Eva ; Hapla, Miroslav ; Ondrůšek, Č. ; Schneeweiss, Oldřich
Electrical steel M470-50A belongs to the most often used materials in electrical machines. Due to this fact, it is desirable to know the magnetic parameters after processing raw sheets into the required shape. Basic parameters of mechanical, electrical, and magnetic properties of the sheets are usually obtained from the producer but the magnetic properties are changing in dependence on additional machining processes. The aim of this study is to describe changes in parameters of magnetic behavior after punching, laser and spark cutting of the original sheets. The basic information of structure was obtained by optical and scanning electron microscopy. The magnetic parameters were acquired from the measuring of magnetic hysteresis loops in dependence on saturation fields and frequencies. The results are discussed from the point of view of applied\ncutting technology with the aim to obtain the best magnetic parameters and consequently a higher efficiency of the final product. Results can be used as input parameters in simulation of the electrical machine.

HYDROGEN ABSORPTION IN A-Co30Fe55B15
Čermák, Jiří ; Král, Lubomír ; Roupcová, Pavla
Hydrogen solved in amorphous alloys (AAs) influences their magnetic characteristics. AAs are also perspective\nas additives that can improve hydrogen storage kinetic in certain types of ball-milled hydrogen storage\nmaterials (HSMs). Therefore, knowledge of hydrogen solubility and hydrogen sorption kinetics in AAs are of a\ngreat importance for aimed design both AAs with optimal magnetic parameters and HSMs with desired sorption\ncharacteristics. In the present paper, amorphous alloy Co30Fe55B15 (an example of the type a-TM1xTM2y Bz ;\nTM - transition metal) was investigated. Hydrogen concentration c H was measured by Sieverts method in\ntemperature interval from T = 150 °C to T = 350 °C under hydrogen pressure p up to 6 MPa. It was found that\nc H was an increasing function of p and its maximum value was typically 0.5 wt.% H2 at 350 °C and 6 MPa.\nHowever, when the alloy was preliminary hydrogen charged (PHC), the pressure dependence of total c Htot in\nthe first absorption cycle(s) is non-monotonous in dependence on PHC conditions. For the sake of comparison,\nthe same absorption characteristics were measured also in Mg2Ni intermetallic that is a common constituent\nin Mg-based HSMs. Comparing Co30Fe55B15 and Mg2Ni, it was concluded that Co30Fe55B15 shows lower\nhydrogen solubility, but much better absorption kinetics.

ELECTRON BEAM REMELTING OF PLASMA SPRAYED ALUMINA COATINGS
Matějíček, Jiří ; Veverka, J. ; Čížek, J. ; Kouřil, J.
Plasma sprayed alumina coatings find numerous applications in various fields, where they enhance the properties of the base material. Examples include thermal barriers, wear resistance, electrical insulation, and diffusion and corrosion barriers. A typical structure of plasma sprayed coatings, containing a multitude of voids and imperfectly bonded interfaces, gives them unique properties - particularly low thermal conductivity, high strain tolerance, etc. However, for certain applications such as permeation barriers or wear resistance, these voids may be detrimental.\nThis paper reports on the first experiments with remelting of plasma sprayed alumina coatings by electron beam technology, with the purpose of densifying the coatings and thereby eliminating the voids. Throughout the study, several parameters of the e-beam device were varied - beam current, traverse velocity and number of passes. The treated coatings were observed by light and electron microscopy and the thickness, structure and surface morphology of the remelted layer were determined and correlated with the process parameters. Based on the first series of experiments, the e-beam settings leading to dense and smooth remelted layer of sufficient thickness were obtained. In this layer, a change of phase composition and a marked increase in hardness were observed.\n

San Minn (or) An Artist who prefer creating and paintings than his life
Zeya, Pyin Nyar ; JANEČEK, Vít (advisor) ; VOJTĚCHOVSKÝ, Miloš (referee)
No one can control a painter artist’s freely thoughts and ideas and although his paintings were under the high pressure and banned by force, the artistic value of his materials never go down. So that I am writing this paper.
He, San Minn has broken out the mainstream of Burmese painting field, he never made business paintings as well. He keeps his belief on the art of paints and he is always finding for the new way to make his paintings. His materials are very different from other Burmese painter artists’ materials. His style is unique in Burmese paintings. So I can get a chance to study of his style, ideas, ways of thinking and his determination on the art works.
My paper can show a painter artist’s life who grew up under the military rule for 50 years and the situation and history of Burmese painting field. Then not only people who are studying the painting subject, but also other people can know about the subject of Burmese painting and field of artists. I dare say that my paper must be colorful and fruitful.
As a painter artist, it seems that he wants his audience to feel his materials but he rare to show his real life behind the pictures. For me, I can get a chance to know about his real life for my thesis paper.
xxxxxxxxxx
Thesis Statement
My thesis can be useful for everybody who is interested in Burmese contemporary art field.
This is the biggest chance to read about one of the most famous, important and significant artists and art movements of Burma. His paintings are reflecting his journey through over 40 years of censorship, but he was not afraid to tackle political and social issues.
Many of San Minn's art works are based on autobiographical, making sharp social commentary on the popular culture, social values and scenario circumstances where he has lived in.

Natural houses in gardens
Formánková, Kristýna ; Kunt, Miroslav (advisor)
Thesis discusses natural houses which are supposed to be part of our lives in the future. These houses may be for someone and they might prefer smarter building with non-recyclable materials when choosing a new housing. But it is necessary to think about our future and sustainable development. We also need to tell ourselves what is really a priority for our planet. There comes a time when they will prefer building materials which can be used somehow after some time or be recycled. This is related to the design of the garden. It is designed to fulfil an ornamental, economic and social function. The garden is an integral part of each house, therefore it is important for each element used to be creating the garden as a linked harmonious whole. The study deals with the concept of a natural houses home in accordance with the maximum use of the garden.
