Hodnocení úspěšnosti účastníků praktické výuky letního a zimního přežití / Evaluating the success of participants practical, summer and winter survival training.

Šika, Vojtěch January 2016 (has links)
Title: Evaluating the success of participants practical, summer and winter survival training. Objectives: The aim of this thesis was to evaluate and interpret the data. This data was collected over a period of several years, and observations were made by experts in the field of survival. Based on the course of the winter and summer survival, the idea was to observe if there are differences between successful men and women who best cope with stress. Observed people are generally students at Charles University. Methods: Data were collected during the course of survival thanks to observing instructors, who in no way influenced the behavior of the students in all activities associated with survival. Evaluating of behavior was conducted on the basis of six criteria established by survival instructors. The students completed the five-factor questionnaire NEOPS that was used to obtain personal profile of individual students. Results: For interpretation of the results was used Eyseneck's coordinate model of temperament. In this model they were recorded individual personality profiles obtained thanks to two fundamental dimensions - neuroticism and extroversion. Over 72% of students participating the survival seminar belong to a sanguine temperament, a person who is emotionally stable and openminded. Along...

Sledování, vyhodnocení a porovnání obsahu nitrátů v zelenině distribuované v obchodní síti vybrané oblasti ČR a přilehlé příhraniční oblasti Rakouska / Monitoring, evaluation and comparison of a nitrate content in vegetables distributed in a network of markets in selected area in the Czech Republic and adjacent regions of Austria

RŮŽEK, Marek January 2013 (has links)
The main aim of this study was to monitor and evaluate nitrate contents in vegetables, offered in the network of markets, from anti-nutritive point of view. The nitrate content was monitored in common vegetable types in the course of a year. The selected supermarkets were used as the source of samples. The ion-selective electrode measurement method was used to set the nitrate content. The analysed samples were provided in Billa markets in Jindřichův Hradec and in Heidenreichstein in Austria. In total 149 samples were analysed, 71 were provided in the Czech markets and 78 in Austria. The leaf and root vegetables were tested, especially lettuce, iceberg lettuce, a carrot, a parsley and a radish. The lowest measured value 21 mg NO3-.kg-1 was taken from the parsley from the Czech Republic. The highest nitrate content was detected in the lettuce also originated from the Czech production and reached 5200 mg NO3-.kg-1. In the final comparison with the neighbouring Austria, the Czech samples have shown, except for the carrot, higher nitrate contents.

Zhodnocení revitalizace vodní nádrže Olešná

Forgačová, Kristýna January 2018 (has links)
This diploma thesis aims to assess the restoration of the Olešná water reservoir. The goal of the thesis is to evaluate the measured values of the risk elements and hazardous substances from the sediments extracted from the Olešná reservoir according to Decree No. 257/2009 Coll. on the Use of Sediments on Agricultural Land. Another objective of the thesis is the analysis of basic parameters of water quality. The selected parameters are aggregate phosphorus, aggregate nitrogen, calcium and magnesium. The results of the monitoring are compared with the values of permissible surface water pollution from the Government Ordinance No. 401/2015 Coll. The source data for this thesis were provided by Povodí Odry, s.p. (Odra River Basin Enterprise). Literature review relates to topics of water reservoirs, soil erosion, sediments, quality and pollution of surface waters.

Beveridgeův-Nelsonův rozklad a jeho aplikace / Beveridge-Nelson decomposition and its applications

Masák, Štěpán January 2015 (has links)
In this work we deal with the Beveridge-Nelson decomposition of a linear process into a trend and a cyclical component. First, we generalize the decom- position for multidimensional linear process and then we use it to prove some of the limit theorems for the process and its special cases, processes VAR and VARMA. Further, we define the concept of cointegration and introduce the po- pular VEC model for cointegrated time series. Finally, we show a method how to deal with infinite sums appearing in calculation of the Beveridge-Nelson decom- position and apply it to real data. Then we compare the results of this method with approximations using partial sums.

Jelínek, Dan January 2020 (has links)
The thesis deals with the design of the production of Ignition case. Component is a hollow cover of one channel ignition device, produced by the PBS Velká Bíteš company. It has a constant wall thickness of 0,5 mm and production rate is 15 000 pieces per year. Technology of deep drawing with solid forming tool was picked out of several considered production variants. DC05 deep drawing steel is the material of choice. Based on technological calculations, number of drawing operations needed and forming force was established. Based on those parameters, hydraulic press ZH 10 produced by the Presshydraulika s.r.o. company was chosen for the task.

Chaotické náhodné veličiny v aplikované pravděpodobnosti / Chaotic random variables in applied probability

Večeřa, Jakub January 2019 (has links)
This thesis deals with modeling of particle processes. In the first part we ex- amine Gibbs facet process on a bounded window with discrete orientation distri- bution and we derive central limit theorem (CLT) for U-statistics of facet process with increasing intensity. We calculate all asymptotic joint moments for interac- tion U-statistics and use the method of moments for deriving the CLT. Moreover we present an alternative proof which makes use of the CLT for U-statistics of a Poisson facet process. In the second part we model planar segment processes given by a density with respect to the Poisson process. Parametric models involve reference distributions of directions and/or lengths of segments. Statistical methods are presented which first estimate scalar parameters by known approaches and then the reference distribution is estimated non-parametrically. We also introduce the Takacs-Fiksel estimate and demonstrate the use of estimators in a simulation study and also using data from actin fibres from stem cells images. In the third part we study a stationary Gibbs particle process with determin- istically bounded particles on Euclidean space defined in terms of a finite range potential and an activity parameter. For small activity parameters, we prove the CLT for certain statistics of this...

Retrospektivní analýza a identifikace možností ovlivnění limitní sportovní výkonnosti / Retrospective analysis and identification of options for limiting sports performance

Semerád, Miroslav January 2018 (has links)
Subject: The knowledge of the sport performance structure with individual identification of the sport training model is a prerequisite for the effective management of sport training. Achieving the sports top limit performance in sport is possible by adapting the training plan to the athlete's individuality by his physiological and psychological prerequisites. To achieve the highest sports performance, sports training analysis is an indispensable tool for international competitiveness. This case study deals with the description of sports training models identified by the composition and dynamics of the training load predictors. A retrospective longitudinal study provides with insights into the possibilities of influencing sports training, which made national, Czech, records on the course of 800 m men and 3,000 m of women's steeplechase. Probandé (n=2) at the age of 21 (runner 1) and 28 resp. 29 years old (runner 2) reached limiting sports performances. The track record dates originates from 1995 to 2012. Runners were participants or medalists from top world or European athletic competitions. Objectiv: The aim of the thesis is to identify retrospectively through the found predictors, by whom were reached limit sports performance and sporting performance in the middle distances run. Methods: The...

Stochastické evoluční rovnice / Stochastic Evolution Equations

Čoupek, Petr January 2017 (has links)
Stochastic Evolution Equations Petr Čoupek Doctoral Thesis Abstract Linear stochastic evolution equations with additive regular Volterra noise are studied in the thesis. Regular Volterra processes need not be Gaussian, Markov or semimartingales, but they admit a certain covariance structure instead. Particular examples cover the fractional Brownian motion of H > 1/2 and, in the non-Gaussian case, the Rosenblatt process. The solution is considered in the mild form, which is given by the variation of constants formula, and takes values either in a separable Hilbert space or the space Lp(D, µ) for large p. In the Hilbert-space setting, existence, space-time regularity and large-time behaviour of the solutions are studied. In the Lp setting, existence and regularity is studied, and in concrete cases of stochastic partial differential equations, the solution is shown to be a space-time continuous random field.

Stabilní rozdělení a jejich aplikace / Stable distributions and their applications

Volchenkova, Irina January 2016 (has links)
The aim of this thesis is to show that the use of heavy-tailed distributions in finance is theoretically unfounded and may cause significant misunderstandings and fallacies in model interpretation. The main reason seems to be a wrong understanding of the concept of the distributional tail. Also in models based on real data it seems more reasonable to concentrate on the central part of the distribution not tails. Powered by TCPDF (www.tcpdf.org)
