Influence of social networks on communication and culture

Má bakalářská práce je zaměřena na problematiku sociálních sítí a jejich vliv na dnešní společnost. Zabývá se jejich historií od prvotních pokusů až po nejnovější globální sociání sítě. Poté práce vysvětluje základní myšlenku vedoucí k vytvoření sociálních sítí i jejich charakteristické znaky. Dále nastiňuje problémy související se snadnou dostupností a nadměrným využíváním sociálních sítí, které následně ovlivňuje lidskou společnost. Práce se věnuje vlivu sociálních sítí na jazyk, mezilidskou komunikaci a kulturní adaptaci.My bachelor thesis is focused on issues with social networking services and their influence on modern society. It addresses their history from the very first attempts to create a social networking service to the modern global ones. Later the thesis provides an explanation of the creation of a social networking service and its characteristic traits. Furthermore it outlines problems connected with the availability and overuse of social networking services that are subsequently influencing the human society. The thesis also analyzes the influence of social networks on language, interpersonal communication and cultural adaptation.

Local spin operators for fermion simulations

Digital quantum simulation of fermionic systems is important in the context of chemistry and physics. Simulating fermionic models on general purpose quantum computers requires imposing a fermionic algebra on spins. The previously studied Jordan-Wigner and Bravyi-Kitaev transformations are two techniques for accomplishing this task. Here we re-examine an auxiliary fermion construction which maps fermionic operators to local operators on spins. The local simulation is performed by relaxing the requirement that the number of spins should match the number of fermionic modes. Instead, auxiliary modes are introduced to enable non-consecutive fermionic couplings to be simulated with constant low-rank tensor products on spins. We connect the auxiliary fermion construction to other topological models and give examples of the construction

Work Environment Parameters and their Measurement

Tato bakalářská práce se zabývá parametry pracovního prostředí a jejich měřením. Pracovnímu prostředí se v dnešní době věnuje velká pozornost, protože výrazně ovlivňuje pohodu a výkony člověka. Jeho vhodnou optimalizací lze současně docílit výrazných ekonomických úspor a zvýšení komfortu pracujících osob.This bachelor thesis deals with the work environments parameters and their measurements. The work environment is being paid a lot of attention nowadays, because it significantly affects the comfort and work performance. With the suitable optimalisation we can achieve significant economic savings and increase the comfort of the employees.

A "problem of time" in the multiplicative scheme for the nn-site hopper

Quantum Measure Theory (QMT) is an approach to quantum mechanics, based on the path integral, in which quantum theory is conceived of as a generalised stochastic process. One of the postulates of QMT is that events with zero quantum measure do not occur, however this is not sufficient to give a full picture of the quantum world. Determining the other postulates is a work in progress and this paper investigates a proposal called the Multiplicative Scheme for QMT in which the physical world corresponds, essentially, to a set of histories from the path integral. This scheme is applied to Sorkin's $n$-site hopper, a discrete, unitary model of a single particle on a ring of $n$ sites, motivated by free Schr\"odinger propagation. It is shown that the multiplicative scheme's global features lead to the conclusion that no non-trivial, time-finite event can occur.Comment: 24 pages, 2 figures. Now published in J. Phys. A: Math.

Hybrid ventilation in buildings

Tato bakalářská práce se zabývá hybridním větráním v budovách. První část práce je věnována větrání, jeho rozdělení a popisu přirozeného a nuceného větrání. Hybridnímu větrání v budovách se věnuje druhá část práce. Je zde uvedeno rozdělení hybridního větrání, 2 ukázky hybridního větrání v nebytovém sektoru a 4 typy hybridních větrácích systémů pro 4 teplotní pásma.This bachelor thesis deals with hybrid ventilation in buildings. The first part of the thesis discusses ventilation, the classification of ventilation and then natural and mechanical ventilation are summarized. The second part focuses on hybrid ventilation. Here the classification of hybrid ventilation, 2 examples of hybrid ventilation in non-residential premises and 4 hybrid ventilation systems for 4 climate zones are mentioned.

Financing of Liabilities Beyond the Service Life of Nuclear Installations

Operation of a nuclear installation is connected with the creation of long-term liabilities for spent fuel management and disposal, and also decommissioning of the installation (power plant, storages). This means that the operator will have to expend considerable amount of financial resources over a long period after the closure of installation. These financial resources will have to be created during operation of the installation. Related costs to be expended in future must be fully included in the price of electricity, in order to ensure fair competition among different operators. Financial resources for future coverage of liabilities must be continuously invested in order to compensate for inflation and to gain some real interest.Any failure by the operator to comply with its liabilities poses an economic and potentially an environmental hazard for operator’s country. Due attention must therefore be paid to assessing connected costs, defining liabilities and ensuring appropriate regulatory oversight. Appropriate measures must be well defined and firmly anchored in the legislation of countries operating nuclear installations. This paper reviews the basic principles that should ensure operator’s compliance their liabilities, and maps the current situation in the Czech Republic.

Philosophie und Politik bei Cicero

The subject of Philosophy and Politics in Cicero include, inter alia, the question of the true statesman, who is characterized by conduct that is based on common interest and the common good of the state. The statesman and philosopher, despite sharing the same views of the good of the state, however differ in the respect that the statesman embraces these values in his behavior and does not linger only in the world of theoretical considerations. Yet Cicero argues against the Epicureans and argues that philosophy should result in behavior and that any behavior should be theoretically based. This confrontation of philosophy and politics stands in the background of the work De republica by Cicero. We will be interested to know what the difference between statesman and philosopher in Cicero's work is
