The mathematical theory of perturbations in cosmology
Novák, Jan ; Pravda, Vojtěch (advisor) ; Scholtz, Martin (referee) ; Chopovsky, A. (referee)
We have been studying Cosmological Perturbation Theory in this thesis. There was presented the Standard General Relativity in higher dimensions. Then we used the apparatus of so called GHP formalism and this is a generalization of the well-known NP-formalism. Scalar perturbations in f(R)-cosmology in the late Universe is the final topic, which was a logical step how to proceed further and to continue in work where was shown that four-dimensional spacetimes are special. We get the potentials φ and ψ for the case of a box 150 Mpc. We used the so called mechanical approach for the case of a cosmological background. Our approach of getting these potentials is in observable Universe new. It is interesting also in the context of simulations in these, so called nonlinear theories. Powered by TCPDF (www.tcpdf.org)

Species diversity of dry basic habitats enclaves within forest environment in the Doksy region: effect of abiotic factors and historical land use
Martinec, Pavel ; Sádlo, Jiří (advisor) ; Novák, Jan (referee)
The primary aim of this thesis was to examine variables that explain species variety of dry bazic biotopes in forrest areas of Doksy landscape. The most important variables are geology, history of biotypes, existence of rock, amount of solar radiation, existence of land disturvation, declinationi and area of biotopy. By the PCNM methodoloby The thesis has examined also area related variables. Primary goal was to examine history related variable that explain 1,2% of the whole species diversity. The thesis distinguished special species with high inclination to historically stable biotopes and those, that are highly correlated with specific land use.The area covered with species-poor acidophilous pine forests on sandstone with isolated patches of basic bedrock with a species-rich flora. In total, 149 localities differing in history were studied. Some anthropogenic disturbances and local history. Main questions: What is the distribution pattern of patches with basiphilous flora and which environmental factors drive their species composition? How the historical land-use since the half of 19th century can influence the current species composition? How is the historical impact detected by functional species traits? Keywords: Secondary habitats, dry calcareous habitats, Pinus sylvestris, abandoned...

Evaluation of short-term effect of Extracorporeal shockwave therapy into muscular trriger points.
Novák, Jan ; Čech, Zdeněk (advisor) ; Vaculín, Šimon (referee)
Diplomová práce Hodnocení krátkodobého efektu aplikace rázové vlny na MTrP Abstract This thesis concerns the application of radial extracorporeal shockwave therapy into muscular trigger points. It's location is derived from the descending part of trapezius muscle on the side of the dominant upper extremity. The performance analysis is based on using partially double-blind placebo-controlled, randomized clinical trial. The effects of the therapy were investigated in 28 subjects divided into experimental and control groups and objectively manifested by measuring the pressure pain threshold. Furthermore, the measuring of the active range of motion of the cervical spine, and the measuring of the maximal voluntary wrist and third finger flexion (measured before and after the therapy). After the therapy, the pressure pain threshold value of the trigger point located in trapezius muscle increased on average from 199 to 295 kPa (p = 0,025). The cervical spine lateral flexion increased on average by 3 degrees towards to the side of non-dominant upper extremity (p = 0,045). This study also investigates the pressure pain threshold value changes of 7 reference points placed remotely from the area of the application. After the shockwave therapy, the pressure pain threshold values of these reference points increased on...

The comparison of two competitive programmes-112 in danger of life TV Nova and Private dramas on Prima Tv.
Novák, Jan ; Šoltys, Otakar (advisor) ; Dorčáková, Jana (referee)
The main topic of my thesis is a comparison of two investigative shows. The comparison is based on tv measurement which were published, for each show, by the television stations. I also used methods of narrative text as a guide through journalistic show same as Lubomír Doležel presented it in his work. I compared the conclusions that come up from the research with the analytical probe in which 86 participations took part. The aim of the work was to find a model of a successful show, so it would have the most perfect structure and it would the most attractive one for audience. Surely, I also focused on the character of the host and how important of an aspect the host is for the choice of the show.

Measurement of dynamic characteristic of check valves
Novák, Jan ; Himr, Daniel (referee) ; Habán, Vladimír (advisor)
Master thesis presents overview of existing types of check valves, their features, uses and issue called "cracking". Experimental part of this thesis focuses on the lift and swing check valves. Results of the measurement are evaluated from non-stationary flow point of view by developing and analyzing static and dynamic characteristics. This thesis takes into account losses and dynamic effects as main viewpoints. Two methods for measuring non-stationary velocities are used. Direct method called Gibson and indirect method laser doppler anemometry. Goal of the master thesis is to increase understanding of the check valves and their applicability.

Financial analysis of a chosen company
NOVÁK, Jan
This work focus on examination of financial situation of company and value evaluation by methods of financial analysis. The teoretical part contains description of subjects using financial analysis, data sources, using methods of financial analysis and definition of basic terms relating to theme. The practical part focus on the financial analysis of a chosen company for the years 2010-2015 by ratios and creditworthy and bankruptcy models. The final results are compared with sector and with recommended values. In conclusion the financial situation of the company is evaluated and recommendations for future development is suggested

The Quaternary Paleoecological Analysis of the Soos National Nature Reserve
Rajdlová, Hana ; Holcová, Katarína (advisor) ; Novák, Jan (referee)
The Quaternary Paleoecological Analysis of the Soos National Nature Reserve The aim of this proposed diploma thesis is to describe the structure of diatom communities in the diatomite deposits of the Soos National Nature Reserve and compare the finding of this thesis with those of older publications. Another aim was to reconstruct the history of the basin trough with the outputs of diatom analysis accomplished in the 3,4 m long sediment profile. The similarity of diatom communites in individual diatomite types was also tested. Key words: subfossil diatoms, Soos National Nature Reserve, paleolimnology, Late Glacial, Holocene

Care of The Soul and Problem of Education
Novák, Jan ; Hogenová, Anna (advisor) ; Prázný, Aleš (referee)
Care of the Soul and Problem of Education The Czech philosopher Jan Patočka shows two different modalities of soul concepts while thinking about Jan Amos Komenský's heritage for contemporary pedagogy. The close-set soul conceptus supposes simply recognizeable world, modern ideas of its controllability and scientific structure scheme. Education, which means care of the soul in three ways - care of the soul in the sense of cosmos order, in the sense of public and in the personal way, means (following close-set conceptus) formation, preparation and setting up the undone young being for life in the modern society. Reflexions of our contemporary situation find out, that modern situation appears as a crisis. This crisis demands a new approach to education, which could be found in the open-set soul concept. The open-set soul could be described as something incomplete, which is searching its fundamentals all the time. Another characteristic shows affinity of the soul for something superior or sense of own finality. Education in this way unveils itself like repeatedly reached humanity. This kind of education does not mean formation or setting up, this kind of education means revealing context of the world, society and finally own personality. Open-set mind should bring responsibility through this revealing....
