Success story DAB in the UK
(2017)
The popularity of digital audio broadcasting in different countries can be explained mainly by means of historical development. In this work, the general technical conditions are explained and the mode of operation is explained. In addition, advantages, disadvantages and alternatives are presented. After that, the development of the digital radio in Germany and the UK is compared with the current situation in order to show how the differences have led to a different distribution and acceptance of the medium.
Obesity is a major public health issue in many countries and its development leads to many severe conditions. Adipose tissue (AT) simply called fat, in males visceral adipose tissues (VAT) are dominant. Estrogens play an important role in many pathological processes.
In this study, one of the subtypes of the estrogen receptor ER-beta is activated using KB (Specific ligand) treatment on VAT.
In this study, I investigated the metabolism effectof KB treatment on VAT using bioinformatics methods.
In this thesis study, I applied several bioinformatics methods such as differential expression gene analysis, pathway analysis, RNA splicing analysis and SNPs callings to make the prediction of the effect of KB treatment on VAT. A list of candidate genes, pathways and SNPs were identified in this study, which could provide some clues to reveal the genetic mechanism underlying the KB treatment effect. The results of my study show that the KB treatment on VAT has caused significant effect.
This thesis proposes a solution to the practical problem of supervising relatively basic mechanic processes in robotics by means of computervision. Supervision happens by comparing the tracked movement with a known, ideal recording of the movement that acts as a model.
First, this thesis analyzes possible approaches to the problem regarding data structures and representation, ways of extracting the data from the recording and ways to compare the data sets of two recordings. Then, a specific solution is implemented in C++ and explained.
The computer based calculation of the sound insulation in between dwellings or the analysis of the transmission in a building are common use in practice of a building acoustic engineer. With the release of the revised DIN 4109 in July 2016 a whole new calculation model was introduced to the German users of this standard. The calculation model and its input data now need to be included into existing calculation software, such as the software SONarchitect ISO of the Spanish developers Sound of Numbers. For this cause this thesis compares the input parameter and the airborne and impact sound transmission of the DIN 4109:2016-07 and European standard EN 12354:2000. With the help of this comparison it now is possible to declare all necessary parameter and calculation procedures for the calculation of the airborne and impact sound insulation between dwellings.
The object of the thesis is the material and information flows in the production systems of enterprises, in particular, of LLC "Kolibri".
As a subject of thesis, the improvement of the management of material and related information flows of the company LLC "Kolibri" was chosen.
The purpose of the thesis is theoretical substantiation and development of practical recommendations for the effective management of the flows of material and information resources of the enterprise on the principles of logistics.
The Blockchain is a technology which has the capabilities to change the way, the world operates. As promising as this may be, there are still many challenges which do not exist or are way simpler to solve in conventional software solutions. Services which are offered over the blockchain suffer from so called Block-confirmation-times where the customer simply has to wait till the transaction is confirmed. In this paper possible solutions to that problem will be examined and challenges that arise from the specific criteria of the Ethereum Blockchain will be analyzed.
In the context of globalization and the internationalization of international markets, mergers and acquisitions are becoming increasingly important for transnational corporations and national economies of countries as a form of internationalization, integration and the way to attract foreign investment. In the framework of this paper, the theoretical aspects of mergers and acquisitions have been analyzed, and the experience of Germany, China and Russia in attracting investments through mergers and acquisitions has been examined, and the success of this method for each country has been assessed.
This bachelor thesis examines two main topics: Corporate Social Responsibility and Corporate Philanthropy as an integral part of it. It was written in order to prove the high importance of business philanthropy in today’s global market and to encourage companies to strengthen their CSR policy so as to contribute to the resolution of social problems. This paper reviews the theoretical framework of CSR, its evolution, types and theories relating to Corporate Philanthropy. Also it represents a comparative analysis of successful practices of corporate philanthropy in pharmaceutical and other global industries predominantly in Europe and USA. This work underlines competitive advantages and important socio-economic impact of CP and suggest recommendations for companies in developing their CSR activities. The subsequent paper is based on internet research using articles, presentations, reports and studies, websites and official legal documents.
This thesis focuses on the introduction of a process for the fracture toughness testing of epoxy resin systems, in the light of the linear elastic fracture mechanic approach. Based on the requirements of ISO 13586, SENB-specimen were designed and especially the precracking process was analysed and the tapping process was optimized by designing and testing a drop-weight device. After successful validating the test process using specimen made of Araldite LY556, the in uence of GNP loading on the fracture toughness was analysed. The pure epoxy showed a KIc of 0.73 MPap
m, being perfectly in line with the manufacturers datasheet. A peak in fracture toughness of 0.83 MPap
m was archived at 1 wt% and a loading rate of 10 mm/min, showing a decreasing trend as the loading is increased further. As the loading rate is increased, the fracture toughness reduces slightly for 0.5 wt% and 2 wt% GNP, but
drops signicantly for 1 wt% GNP obliterating the peak. The load vs. displacement curves showed quasi-brittle material behaviour. The fracture surfaces were analysed using SEM and while the neat resin did not show any features, did the reinforced samples show pattern of crack pinning in connection with bridging and pull-out. The resulting improvement is less signicant as observed by other researchers for larger GNPs. This is in line with the general idea, that small particles are not able to yield as high improvements, but the signicant decrease for higher loading rates is not observed or described so far. It is suspected that tests at lower loading rates (e.g. 1 or 0.5 mm/min) show an even higher fracture toughness.
Aminoacyl-tRNA synthetases (aaRSs) are key enzymes in the process of protein biosynthesis, charging tRNA molecules with their corresponding amino acid. Whereas adenosine phosphate fixation is common to all aaRSs, recognition of the respective amino acid to ensure correct translation poses a complex task, which is still not understood to its full extent. Using all aaRS structures in the Protein Data Bank (PDB), this thesis reveals further details about the specificitydetermining interactions of each aaRS. Moreover, inspection of the similarities between these enzymes using the structure-derived interaction data reinforces the sequence-based evolutionary trace of aaRSs to a certain degree: The concurrent development of two distinct Classes of aaRS is apparent at functional level, and previously determined evolutionary subclasses coincide altogether with specific aminoacyl recognition in each aaRS Type. Still, discrimination of amino acids in aaRSs involves a multitude of further relevant mechanisms. Eventually, analysis of specificity-relevant binding site interactions sheds light on how aaRS evolved to distinguish different amino acids.
