This thesis focuses on the effectiveness of marketing tools available in Czech internet environment. The theoretical part describes typical attributes and advantages of individual tools and observes the possibilities of achieving marketing and commercial goals by using these tools. In the application part, the surveyed e-shop is introduced and it's marketing tools are analyzed using web analytics. Either behaviour of customers of this e-shop or financial indicators, which are crucial for evaluating performance, are analyzed in this thesis. The synergic effect of using these marketing channels is evaluated using the assisted conversions analysis. The main goals of this thesis is evaluation of the efficiency of used marketing tools using web analytics and consider suitability of their use for this specific e-shop. Another aim is comparing the performance of individual marketing sources and proposing measures to help increase efficiency of tools used by this e-shop.

I denna uppsats studeras Per Anders Fogelströms historiska roman Mina drömmars stad. Undersökningen har två syften. Det primära syftet är att undersöka hur maskulinitet konstrueras och upprätthålls av de två manliga huvudkaraktärerna. Denna del av undersökningen utgår från R.W. Connells maskulinitetsteori och genomförs med metoden karaktärsanalys. Det sekundära syftet är att undersöka romanens handling och karaktärer utifrån John Stephens kulturrelativistiska perspektiv. Undersökningens resultat visar att de två manliga huvudkaraktärerna eftersträvar att uppnå hegemoniska maskulinitetsideal i olika sociala grupperingar, men att deras framgång i denna strävan skiljer sig, samt att de olika maskuliniteterna samspelar med och påverkar varandra. Utifrån den kulturrelativistiska teorin visar undersökningen att 1950-talets samhälle och värderingar på flera plan avspeglas i karaktärerna och berättelsen som tilldrar sig i Stockholm 1860-1880.

While real-time applications are nowadays routinely used in visualizing large nu- merical simulations and volumes, handling these large-scale datasets requires high-end graphics clusters or supercomputers to process and visualize them. However, not all users have access to powerful clusters. Therefore, it is challenging to come up with a visualization approach that provides insight to large-scale datasets on a single com- puter. Explorable images (EI) is one of the methods that allows users to handle large data on a single workstation. Although it is a view-dependent method, it combines both exploration and modification of visual aspects without re-accessing the original huge data. In this thesis, we propose a novel image-based method that applies the concept of EI in visualizing large flow-field pathlines data. The goal of our work is to provide an optimized image-based method, which scales well with the dataset size. Our approach is based on constructing a per-pixel linked list data structure in which each pixel contains a list of pathlines segments. With this view-dependent method it is possible to filter, color-code and explore large-scale flow data in real-time. In addition, optimization techniques such as early-ray termination and deferred shading are applied, which further improves the performance and scalability of our approach.

The thesis focuses on the optical access networks and deals with the issue of transmission parameters of the physical layer, their negative impact on the quality of the services parameters and the possibilities of reducing their effect using the polarization multiplexing. The first and second chapter describe the theoretical background necessary for understanding the subsequent parts. The third chapter contains the practical part of the thesis. At first the optical routes in the Czech Republic in terms of polarization mode dispersion, which is together with insertion loss the main limiting parameter of high-speed optical networks, are evaluated. In the following part the measuring of the temperature changes effects on the polarization mode dispersion of the passive components and the effect of temperature changes to the polarization multiplexed signal are evaluated. To double the bandwidth and reduce the influence of polarization mode dispersion on the quality of services, the two simulation models of optical access networks using polarization multiplexing were carried out. These theoretical outputs were verified by the practical measurements in the laboratory and subsequently on the real optical route. Finally, a draft of the broadband optical access network based on wavelength and polarization multiplexing was designed based on obtained knowledge.

Although a number of studies have been conducted to understand the impact of ICT on a country’s economic output; a complete account for ICT’s influence on real GDP per capita has yet to be visualized. This study aims to investigate this topic, by exploring the hypothesis whether ICT has an impact (causal relationship) on real GDP per worker in 41 European countries from 1996-2010. Confidence in the judicial system is taken as an instrument to solve for endogeneity problems. ICT is defined as mobile, broadband and internet penetration per 100 people. We find that confidence in the justice system is a strong instrument for ICT. Therefore, using IV 2sls regression, it is observed that ICT does have a strong positive correlation and causal relationship with GDP per worker, with an elasticity of 0.4 between the variables. In light of the results, the author recommends that economic policies must be tailored to support ICT development in countries.

I studien analyseras sambandet mellan aktieprisvolatilitet (SPV) och utdelningspolicy (utdelning och utdelningsgrad) för svenska företag som är noterade på Stockholmsbörsens Large Cap lista. Urvalet består av 58 företag under tidsperioden 2015-2019. Multipel regressionsanalys har tillämpats på paneldata. För att styrka studiens resultat samt urskilja om kontrollvariablerna företagsstorlek (FS), vinstvolatilitet (EV), långsiktiga skulder (Debt), tillväxten (Growth) och vinst per aktie (EPS) har ett samband till aktieprisvolatiliteten. Studien bidrar till den begränsade mängd forskning om utdelningspolicy, kontrollvariabler och dess relation till aktieprisvolatilitet hos Large Cap företagen på den svenska aktiemarknaden. Studiens resultat finner ett statistiskt negativt signifikant samband för företagsstorlek i förhållande till aktieprisvolatilitet, samt ett statistiskt positivt signifikant samband mellan vinstvolatilitet och aktieprisvolatilitet. Enligt resultatet har utdelning och utdelningsgrad inget statistiskt signifikant samband till aktieprisvolatiliteten.
