Příprava a polymerizace monomerů odvozených od ethynylpyridinů / Preparation and polymerization ethynyl pyridine based monomersFaukner, Tomáš January 2011 (has links)
A group of monomers based on disubstitued ethynylpyridine (3-PyCCPh-4-t-Bu, 2-PyCCR, R = 4-t-BuPh, 2-Py, n-Bu) and 4-tert-butyphenylethynyl (4-t-BuPhCCPh-p-OR, R = SiPh2-t-Bu, Si-i-Pr3) were prepared by Sonogashira cross-coupling reaction (PdCl2[(PPh3]2/CuI). All of these monomers were charakterized by IR, UV/vis and NMR spectroscopy. Ethynylpyridine based monomers were polymerised by quarternization (ethylbromid was used as a quarternization agent) and by Grubbs-Hoveyda 2nd generation catalyst. As a product of the quarternization were obtained oligomers compounded by 2 - 13 monomers units (Mw: 1600 - 6000, Y 70%). Only low molecular weight oligomers were also obtained by Grubbs-Hoveyda 2nd generation polymerization (Mw: 400 - 1500, Y 34 %). Monomers based on 4-tert-butyphenylethynyl were polymerized by TaCl5/Bu4Sn/Toluen catalytic system. In that case were obatined polymers (Mw: 64 000 - 200 000, IP = 2,3 -3,9, Y 75 %). Products of polymeryzations were charakterized by GPC, IR, UV/vis and NMR spectroscopy.

Odlehlá pozorování / OutliersKudrnáč, Vojtěch January 2015 (has links)
This paper concerns itself with the methods of identifying outliers in an otherwise normally distributed data set. Several significant tests and criteria designed for this purpose are described here, Peirce's criterion, Chauvenet's criterion, Grubbs' test, Dixon's test and Cochran's test. Deriving of the tests and criteria is indicated and finally the results of the use of the test and criteria on simulated data with normal distribution and inserted outlier are looked into. Codes in programming language R with the implementation of these test and criteria using existing functions are included. Powered by TCPDF (www.tcpdf.org)

Posouzení vlivu územního plánování na cenu pozemků v Prostějově a jeho okolí / Evaluation of the Impact of Town and Country Planning on the Land Prices in Prostějov and its SurroundingsHrubanová, Michaela January 2010 (has links)
The thesis is focused on setting land prices according to the rules of valuation and market price (the current). Selected lands are placed in non-structural locations and locations designed to be constructed at selected stages of landscape planning. Based on gained results was made evaluation of how various stages of landscape planning affects the current price and also the administrative price. The thesis also explains the cause of the difference and way how it affects the price of invested land.

Posouzení vlivu územního plánování na cenu pozemku v Milínově / Evaluation of the Impact of Town and Country Planning on the Land Price in MilínovDoláková, Markéta January 2013 (has links)
In this dipoma is priced selected lend and administrative costs by pricing regulation and market price, which is performed by a professional estimate using the comparsion (comparative) method. A case study is considered prices of land in connection with changes in the landscape plan and implementation strategy for rural development. It was also evaluated the degree to which the emergence of zoning and development of services and facilities in rural areas affects the amount of land prices.
