Abstract:

Pomocí molekulového modelování je možné předpovídat chování nových látek a napomáhá při jinak obtížné interpretaci experimentálních dat. Cílem práce byla predikce vybraných vlastností polymeračních katalyzátorů na bázi karbenů, predikce jejich struktur a spektrálních charakteristik a studie mechanismu polymerace za otevření kruhu laktidu. K ověření chování karbenů a jejich prekurzorů ve formě chloridů byly studovány vybrané charakteristiky molekuly. Byl proveden výpočet vybraných molekulových orbitalů a elektrostatických map. Následně pomocí počítačových programů byly získány teoretické vazebn

Abstract:

The work is focused on the obtaining thermochemical properties of the linear polynitramines to predict their detonation properties. The basic thermochemical parameters are enthalpies ?f H° (298,g) in the gas and solid phase as well. The values of the enthalpy in the gas phase were obtained at a theoretical level by quantum chemical DFT calculations using both an isodesmic reactions and direct thermochemical G-Gaussian recipes. Conversion to the enthalpy in the solid phase ?f H° (298,s) was carried out using sublimation enthalpies ?s H° (298,g) obtained on the empirical level. The results were

Abstract:

The subject of this master’s thesis is to analyze and evaluate the economic indicators of selected company and comparison of these indicators with the nearest competitors. The thesis is divided into three main sections. First part is theoretical and contains information about used economical and statistical terms. Second part contains of analysis of economic indicators, comparison of actual and predicted values and comparison with the nearest competitors. In order to predict future values of indicators, on selected indicators appropriate regression function has been applied. The last part of t

Abstract:

These master’s theses present the review of design support methods. Mechanical part design plays an important role whether company will succeed in market or will fail. In the first part I describe some systematical design support methods and tools, such like axiomatic design and group technology. From my point of view there are three measures of the design process: cost, quality and time, which are pivotal in design process. Regardless of the product being designed – whether it is an entire system or some small subpart of a larger product – the customer and management always want it cheaper,

Abstract:

Syftet med föreliggande studie var att undersöka hur ryttare upplever Flow, och vidare även hur ryttare upplever samspelet inom ekipaget vid Flow. Studien inkluderade 10 kvinnliga informanter (M = 18.7, SD = 1.48) med tävlingserfarenhet som sträcker sig från ingen alls till internationell nivå (Hoppning= 4, Dressyr = 3, Fälttävlan = 2, Ingen tävling = 1). En semi-strukturerad intervjuguide utvecklades utifrån Csikszentmihalyi's holistiska perspektiv på de nio dimensionerna av Flow (Jackson & Csikszentmihalyi, 1999), och data analyserades kvalitativt genom en innehållsanalys.

Abstract:

The main purpose of panel studies is to analyze changes in values of studied variables over time. In micro panel research, a large number of elements are periodically observed within the relatively short time period of just a few years. Moreover, the number of repeated measurements is small. This dissertation deals with contemporary approaches to the regression and the clustering analysis of micro panel data. One of the approaches to the micro panel analysis is to use multivariate statistical models originally designed for crosssectional data and modify them in order to take into account the w

The doctoral thesis deals with reliability (dependability) analyses of operation and testing data of the Airplanes. Requirements of airworthiness regulations on aircraft hydraulic systems (with a focus on US FAR-23 and European CS-23 regulations) are taken into account. Mentioned regulations include requirements for the structural design, design of systems, etc. They cover wide range of airplanes from small sport airplanes to 19-seats transport aircraft. Also options for predictive reliability analyses (resources) and reliability tests are discussed in the doctoral thesis. Practical applicatio

Abstract:

no<br>In the 2007 blind test of crystal structure prediction hosted by the Cambridge Crystallographic Data Centre (CCDC), a hybrid DFT/MM method correctly ranked each of the four experimental structures as having the lowest lattice energy of all the crystal structures predicted for each molecule. The work presented here further validates this hybrid method by optimizing the crystal structures (experimental and submitted) of the first three CCDC blind tests held in 1999, 2001, and 2004. Except for the crystal structures of compound IX, all structures were reminimized and ranked according to the
