An asynchronous three-field domain decomposition method for first-order evolution problems

summary:We present an asynchronous multi-domain time integration algorithm with a dual domain decomposition method for the initial boundary-value problems for a parabolic equation. For efficient parallel computing, we apply the three-field domain decomposition method with local Lagrange multipliers to ensure the continuity of the primary unknowns at the interface between subdomains. The implicit method for time discretization and the multi-domain spatial decomposition enable us to use different time steps (subcycling) on different parts of a computational domain, and thus efficiently capture the underlying physics with less computational effort. We illustrate the performance of the proposed multi-domain time integrator by means of a simple numerical example

Evaluation of the Impact of Selected Factors on Bitcoin Price

Diplomová práce je zaměřena na popsání teoretických poznatků o kryptoměně bitcoin a také na prokázání existence vztahu bitcoinu s vybranými ekonomickými veličinami. Cílem práce je zhodnocení vlivu vybraných faktorů na vývoj ceny bitcoinu v rámci pětiletého období 7/2012 – 7/2017. Mezi vybrané faktory patří množství vytěžených bitcoinů, množství transakcí bitcoinu za den, hodnota akciového indexu Standard &Poor´s 500, efektivní sazba federálních fondů, cena zlata, hodnota akciového indexu SSE Composite a průměrná cena elektřiny na americkém trhu. Zhodnocení vlivu těchto faktorů bylo provedeno na základě sedmi jednofaktorových modelů a následně také pomocí dvou více faktorových modelů. Diplomová práce je rozdělena do pěti kapitol. První kapitolou je úvod. Druhá kapitola obsahuje teoretický popis kryptoměny bitcoin. Třetí kapitola obsahuje teoretické vymezení metod ekonometrické analýzy. Ve čtvrté kapitole jsou zhodnoceny jednotlivé faktory pomocí sedmi jedno faktorových a dvou více faktorových modelů. V závěru diplomové práce jsou shrnuty dosažené výsledky.The aim of this thesis is to describe the theoretical background of the cryptocurrency of Bitcoin and also to prove the interconnection between Bitcoin and selected economic quantities. The aim is to evaluate the selected factors’ influence on Bitcoin price development within the five-year-period of July 2012 – July 2017. The factors include the amount of mined Bitcoins, the volume of Bitcoin transactions per day, the value of the Standard& Poor’s 500 stock index, Effective Federal Funds Rate, gold price, SSE Composite stock index value and the average electricity price on the American market. The evaluation of these factors has been based on seven single-factor models, and further also on two multi- factor models. This thesis is divided in five chapters. The first chapter is the introduction. The second chapter deals with the theoretical description of Bitcoin cryptocurrency. The third chapter deals with the theoretical definition of Econometric Analysis methods. The fourth chapter evaluates the individual factors, based on the seven single-factor and two multi-factor models. The conclusion summarizes the achieved results.154 - Katedra financívelmi dobř

Coupled heat transport and Darcian water flow in freezing soils

summary:The model of coupled heat transport and Darcian water flow in unsaturated soils and in conditions of freezing and thawing is analyzed. In this contribution, we present results concerning the existence of the numerical solution. Numerical scheme is based on semi-implicit discretization in time. This work illustrates its performance for a problem of freezing processes in vertical soil columns

Mathematical modeling of hygro-thermal processes in deformed porous media

summary:In this contribution we propose a model of coupled heat and moisture transport in variable saturated deformed porous media. Solution of this model provides temperature, moisture content and strain as a function of space and time. We present the detailed description of the model and a~numerical illustrative example

Immigration and Integration policy af Great Britain and Political Mobilization of Ethnic Minorities of Immigrant Origin in 2/2 of 20.century

Great Britain is one of the most important European immigration countries - as for number as well as diversity of newcomers who have come in the period after the end of the World War II. Imperial history of Britain, or more precisely, the existence of the Commonwealth (which in fact arose by transformation of empire) played a significant role in this process. Citizens of both old and new commonwealth countries were thanks to membership of their countries in Commonwealth logically a privileged group of applicants for living in Britain. They had very often good connections thanks to, for example, contacts with British colonial administration in their countries and also knowledge of English language was a great advantage for them in compare with other groups of migrants and facilitated them to integrate into the host society. However, it is important to mention that immigration of non­ white non-European immigrants was since the beginning seen with suspicion and immigration policy was to a great extent influenced by pragmatism. British politicians had to solve a dilemma: either to implement strict immigration controls on all Commonwealth or accept immigration from new Commonwealth countries as accessory effect of old immigration. They accepted the transformation of United Kingdom into multicultural society not..
