DYNAMICKÁ ANALÝZA ZÁKLADOVÉ KONSTRUKCE V INTERAKCI S PODZÁKLADÍM / DYNAMIC ANALYSIS OF THE SOIL-FOUNDATION INTERACTION

Martinásek, Josef Unknown Date (has links)
Thesis deals with problems of the soil-structure interaction. In the theoretical part is described the approach to mathematical modeling of structure-foundation-soil interaction. The subsoil models are further described in detail, including the models with piles (both static and dynamics models). In the next chapter there is described the dynamics theory of the systems with single or more degrees of freedom. There is also an analysis of propagation, reflection and refraction of mechanical one-dimensional waves (P-wave, S-wave) and spatial waves (P- wave, SV-wave, SH-wave) and waves in homogeneous half-space (R-wave L-wave). The numerical analysis is logically sorted from hand calculation of the parameter change influence on the modal characteristics to complex computational FEM model of the machine with a foundation on piles placed in the spatial block of soil. Numerical studies aim to determine the influence of the subsoil model on the modal characteristics and thus confirm the absolute necessity of the subsoil model in tasks of dynamics. The next goal is to determine the appropriate key parameters of the computational model: the size of finite element, suitable shape of subsoil model, suitable inclination of boundary condition and suitable boundary conditions. For creating of set of computational models was used language APDL in conjunction with ANSYS software interface. All used input files are listed in the Annex.

Sledování vlastností kvasinek v průběhu kvašení piva / Investigation of yeast properties during the beer fermentation

Kociánová, Lenka January 2008 (has links)
In this diploma thesis, the properities of brewery’s yeasts during the operation beer fermentation in the selected brewery and dependences of diferent agents and their influence on viability and vitality of the yeasts were studied. Other observed properities were physiological state, pH, temperature, a value of soft and coarse sludges, a value of dissolved oxygen in wort, the level of wort’s fermentation. It were collected the samples of fermenting wort and washing yeasts for determination. The used yeasts were observed from the first time until thein last used (generally 4 times). pH, temperature, apparent fermenting and total numer of yeast cells were measured in the collected samples. The used yeasts were washed before every other application and vitality was determined. The number of death cells were observed by this method. The number of death cells never fell bellow 5 %. The value of dissolved oxygen in wort is also the important agent for the growth of yeasts. The touchs with low number of oxygen showed that the time for fermentation had to be longer (by about 3 or 4 days more). The touchs with higher number of sludges showed that the sludges haven’t any influence on the yeasts and the procces of fermentation. Confirm the accuracy of the repeated used of the yeasts was the object of this thesis.

Listen Up! : A study of how teachers in SLA approach the listening skill within upper secondary schools in Sweden

Andersson, Julia, Lagerström, Elin January 2020 (has links)
Listening comprehension and listening strategies plays a crucial role in the process of acquiring a language. This study aims to investigate to what extent the listening skill is practised in upper secondary schools in the south of Sweden. Research studies within the field of listening are few which indicates that the listening skill is not considered as essential in second language teaching as the other three skills: reading, writing and speaking. Previous studies indicate that teachers should educate students metacognitive awareness when teaching listening. The results summarize the teachers’ answers, reflections and attitudes conducted from semi-structured interviews. The analysis of the results focuses on the four categories distinguished from the teachers’ answers: Teaching Approaches, National Exams, The Individual Student and Metacognitive Awareness. Some of the teachers do not possess the knowledge of how to teach listening that develops students' listening proficiency. As a conclusion, the study shows that a hierarchy exists among the four skills to which teachers adjust to, and this may be detrimental in achieving educational aims.

Evolution of EU corporate R&D in the global economy: intensity gap, sectors' dynamics, specialisation and growth

Moncada Paternò Castello, Pietro 20 October 2017 (has links) (PDF)
The Thesis is composed by three complementary research investigations on the economic and policy aspects of EU corporate R&D.Collectively, the work first reviews the theoretical and empirical literature of corporate R&D intensity decomposition; it then investigates the EU R&D intensity and its decomposition elements comparatively with most closed competitors and with emerging economies over the period 2005-2013. Finally, it inspects further some key aspects that can be associated to the EU R&D intensity gap: sectoral dynamics and the resulting sectoral and technological specialisations as well as the drivers for R&D investment growth across sectors and firms' age groups of top R&D investing firms over time. These studies also address the possible policy implications that derive from their outcomes.The investigations rely on literature as well as on company data, mainly from nine editions (2006-2014) of the EU Industrial R&D Investment Scoreboard. For analytical purposes they use literature review, meta-analysis, descriptive statistics, R&D intensity decomposition computational approach, Manhattan distance and Technological Revealed Comparative Advantage metrics, and a multinominal logit regression model. The results of these three research works are novel in several aspects. It indicates that literature results on R&D intensity decomposition differ because of data and methodological heterogeneities, and that the structural cause is the main determinant of EU R&D intensity gap if sector compositions of the countries are considered. It inspects how the use of different data sources and analytical methods impact differently on R&D intensity decomposition results, and what the analytical and policy implications are.The empirical research results of this Thesis confirm the structural nature of the EU R&D intensity gap. In the last decade the gap between the EU and the USA has widened, whereas the EU gap with Japan has remained relatively stable. In contrast, the emerging countries' R&D intensity gap compared to the EU has remained relatively stable, while companies from emerging economies are considerably reducing such gap. Besides, as novel contribution to the state of the art of the literature, this Thesis uncovers the differences between EU and US by inspecting which sectors, countries and firms are more accountable for the aggregate R&D intensity performance of these two economies, and it finds a high heterogeneity of firms' R&D intensity within sectors. Furthermore, it shows that there is a bigger population of both larger and smaller US top R&D firms which invest more strongly in R&D than competitors, and that the global R&D investment is concentrated in a few firms, countries and industries. Finally, the research founds a slightly higher EU R&D shift over sectors compared to the US, but not strongly enough towards high-tech sectors. Also, the EU has an even broader technological specialisation than its already broad industrial R&D sector specialisation, while the USA leads by number of technological fields belonging mostly to the industrial R&D sectors of its specialisation. Furthermore, the EU has been better able than the USA and Japan to maintain its world share of R&D investment even during the years of economic and financial crisis. Lastly, the study also indicates that firms make a complementary use of capital expenditures and R&D intensity for their R&D investment growth strategies and it reveals that there are differences in their use between firms' age classes across sectors. Overall, the main results of the Thesis suggest that to reach a more positive R&D dynamics and boost its competitiveness, the EU should adapt its industrial structure and increase the weight of high R&D intensive sectors. A focus on creating the conditions for firm creation and growth in new-emerging innovative sectors is advised together with favouring the exploitation of the full capacity of EU leading - but mature - sectors to also absorb high-technology from other sectors. / Doctorat en Sciences économiques et de gestion / info:eu-repo/semantics/nonPublished

Předvolební strategie malých politických stran: Případová studie TOP 09, Věcí veřejných a Strany práv občanů - Zemanovci pro volby do PS PČR 2010 / Election Strategy of Small Political Parties: Case Study on TOP 09, Public Affairs Party and Party of Civic Rights - Zemanovci before Czech Parliamentary Elections 2010

Kapuciánová, Aneta January 2012 (has links)
Diploma thesis Election Strategy of Small Political Parties: Case Study on TOP 09, Public Affairs Party and Party of Civic Rights - Zemanovci before Czech Parliamentary Elections 2010 assesses the election campaign of mentioned political parties, their personal, communication and financial strategy as well as their strategy of inter-parties relations. The author assumes that the small political parties, which all of the examined ones were at the time of this research, lead the campaign in a similar way - avoiding the negative campaign, they are led by a strong and well-known personality who can attract the attention not only of the voters but also of the media, and they have a large number of supporters who sympathize with the particular political entity. The theoretical concept of the text is based on the similarity of political and economic approach of marketing - therefore the author reckons the small political parties as the nichers of the political market. They can be characterized by occupying only a small niche of the political market which is ignored by the bigger political parties for those it is place of peripheral importance. Hence the basis of electoral campaign of any small political party is delineation unoccupied part of the market. Nevertheless it is crucial to simultaneously...

Made in Grønland : How can a designer facilitate the activation of a community in the face of top-down regeneration? / Tillverkad i Grønland : Hur kan en designer underlätta aktiveringen av en samfund i anseende av topstyrd nydaning?

Miller, Rebecca January 2016 (has links)
Cities are highly unequal systems and rapid, top-down development is increasingly causing segregation between people of different socio-economic statuses through gentrification. In response, a bottom-up, more community centred approach is often proposed, yet this method also not without significant issues. In this thesis I investigate the role of the designer as a mediator, facilitator and translator between the top-down and bottom-up approaches to urban development. Using Grønland, Oslo as a case study, I start by gathering high-level research in order to understand the large-scale strategies that the municipality and private developers have for the area. In the second section, I undertake on-the-ground research in order to understand the everyday issues that people who live in, or use, the area face. In the final section I propose a research laboratory and makerspace that can activate the local community, providing the resources in order for everyday people to be able to have a positive impact on their city, in addition to gathering long-term, in-depth research on the area in order to influence the future of Grønland. This thesis is written as a working document that can, and should, be used by a wide range of people, from the municipality to local residents, and is designed to be added to as the project develops.
