Protection against DDoS attacks in the cloud computing
Vavroch, Zdeněk ; Karkošková, Soňa (advisor) ; Jelínek, Ivan (referee)
DDoS Attacks are nowadays huge threat on the internet. Many people and companies are dependent on accessibility of their data, services or applications. And that is what attackers try to abuse. In some cases, site or application that is not working, can make very bad name for the company in public. DDoS attacks are dangerous for people working at home, for corporate networks and mainly for huge clouds. Cloud are often targets of attacks because of how many people are affected by it. This thesis is focused on types of DDoS attacks we know and goal of the thesis is to find best defense solutions, mainly for defending the cloud computing. I will choose and describe the most common methods we know and use. In theoretical part I will describe what is cloud computing and DDoS attacks and what types of DDoS we know. In practical part I will describe the most common and efficient methods of defense.

Impact of low oil and natural gas prices on the economy of Qatar since 2014
Šamánek, Ondřej ; Stuchlíková, Zuzana (advisor) ; Hasík, Gabriel (referee)
The bachelor thesis examines the impact of the oil and gas prices slump, which befell the world in 2014, on the economy of Qatar. The main objective of the thesis is to evaluate if and to what extend the price collapse influenced the relevant economic indicators and behaviour of the state and companies active in the affected field. The selected objective is examined using the method of data comparison, namely before and after the price slump, and with the help of the case study, in which the qatari company operating in the oil and gas is examined. From the conducted analysis it is possible to conclude that Qatar was directly influenced by the oil and gas prices collapse: its GDP slumped, fiscal deficit increased. The analysed company also experienced troubles caused by low prices: one year after the price slump, total amount of assigned tenders to company decreased substantially and historically high number of tenders was cancelled. Conclusions deriving from the thesis might be applied to other oil and gas export economies in the Persian Gulf, for fundamental traits of such economies are shared with the economy of Qatar.

Design of processes of business department in IT company and measuring their performance
Schütz, Martin ; Oškrdal, Václav (advisor) ; Bruckner, Tomáš (referee)
The thesis deals with design of new processes of business department in IT company which provides server hosting, web hosting and domain registration services. These processes come from identification and analysis of current processes and the theory of business department management. Key Performance Indicators (KPIs) were set for selected processes which can be used for managing the company as a whole. Models of processes were created due to EPC notation. New processes were designed to continuously create data in CRM information system providing evidential and information support necessary for business department management, including the possibility of measuring its performance. Processes also automatize often repetitive activities and provide relevant information to other affected business units within the company. Contribution of the thesis lies in results of analysis of current identified processes containing solution proposals of discovered problems and newly created process models. Both can be used as a pattern for optimization of current processes in already existing organization or for designing new process models in new organization in the same or similar field of business.

Older workers in the labour market
Pazderníková, Michaela ; Pavelka, Tomáš (advisor) ; Sirůček, Pavel (referee)
The thesis is dealing with the older workers in the labour market. The aim of this thesis is to analyse and evaluate the situation of the older workers in the labour market in the Czech Republic, especially in the years 2000 and 2005-2015, or even in 2015, with the focus on the indicators of the labour market, on the position of the older workers in this market according to selected aspects, and on the instruments affecting and encouraging these workers in the labour market. The thesis consists of the theoretical and the practical part. The theoretical part defines the problem of the demographic aging population, because this process is one of the reasons, why it is necessary to pay attention to the older workers in the labour market. This theoretical part is also dealing with the employment, unemployment, employment policy and strategic documents in relation to the older workers. The practical part begins with the demographic development in the Czech Republic, the following chapters are dealing with the analysis of the labour market indicators, instruments to support the older workers in the labour market and the comparison of the Czech Republic and EU states.

Optimal production strategy of the chosen company in the area of mechanical engineering
Brachtlová, Veronika ; Průša, Přemysl (advisor) ; Všetečková, Dana (referee)
The topic of this diploma thesis is "Optimal production strategy of the chosen company in the area of mechanical engineering" - namely the EUTECH join stock company, or more precisely its toolshop division, which deals with the manufacture of injection moulds, parts and production of special devices for aircraft industry. The aim of the paper is to evaluate, according to the defined factors, what is for the EUTECH join stock company more favourable - invest in purchase of the 5-Axis CNC machining center technology and deal with this process inside of the company or ensure this technology in cooperation with another companies. The thesis is divided into two main parts - theoretical and practical. In the theoretical part, the subjects of operation management theory and production are dealt with. The practical part deals with the production strategy of the EUTECH join stock company, or more precisely of its toolshop division in detail. The company is briefly introduced, the situational analysis of division toolshop is conducted and the production process of the company is examined. The final chapter deals with the use of cooperation in the toolshop division. The main and other factors affecting the choice of "product or sell" strategy are evaluated and consequently is decided which strategy is in case of the 5-Axis CNC machining center technology more favourable.

STRAIN ENGINEERING OF THE ELECTRONIC STRUCTURE OF 2D MATERIALS
del Corro, Elena ; Peňa-Alvarez, M. ; Morales-García, A. ; Bouša, Milan ; Řáhová, Jaroslava ; Kavan, Ladislav ; Kalbáč, Martin ; Frank, Otakar
The research on graphene has attracted much attention since its first successful preparation in 2004. It possesses many unique properties, such as an extreme stiffness and strength, high electron mobility, ballistic transport even at room temperature, superior thermal conductivity and many others. The affection for graphene was followed swiftly by a keen interest in other two dimensional materials like transition metal dichalcogenides. As has been predicted and in part proven experimentally, the electronic properties of these materials can be modified by various means. The most common ones include covalent or non-covalent chemistry, electrochemical, gate or atomic doping, or quantum confinement. None of these methods has proven universal enough in terms of the devices' characteristics or scalability. However, another approach is known mechanical strain/stress, but experiments in that direction are scarce, in spite of their high promises.\nThe primary challenge consists in the understanding of the mechanical properties of 2D materials and in the ability to quantify the lattice deformation. Several techniques can be then used to apply strain to the specimens and thus to induce changes in their electronic structure. We will review their basic concepts and some of the examples so far documented experimentally and/or theoretically.
