Sustainable distribution
(2020)
This master thesis gives an insight into the topic of sustainability in the banking industry and focuses on distribution. In the first part of the thesis, the terms and concepts of sustainability and sustainable distribution are being explained and existing methods for measuring sustainability are presented on the basis of an extensive literature research.
Subsequently, the banking industry is introduced, the distribution of financial services is explained, and the specifics of sustainable distribution in the banking industry are elaborated.
An empirical study in form of expert interviews was used to show to what extent sustainability currently plays or will play a role in the banking sector. For this purpose, experts from six banks were interviewed.
In the final part of the paper, the hypotheses formulated at the beginning of the paper as well as additional questions are examined or answered and a model for evaluating the effects of selected distribution channels on ecological and social sustainability is being presented.
Nowadays, the area of customer management strives for omni-channel and state-of-the-art CRM concepts including Artificial Intelligence and the approach of Customer Experience. As a result, modern CRM solutions are essential tools for supporting customer processes in Marketing, Sales and Service. AI-driven CRM accelerates sales cycles, improves lead generation and qualification, and enables highly personalized marketing. The focus of this thesis is to present the basics of Customer Relationship Management, to show the latest Gartner insights about CRM and CX, and to demonstrate an AI Business Framework, which introduces AI use cases that are used as a basis for the expert interviews conducted in an international B2B company. AI will transform CX through a better understanding of customer behavior. The following research questions are answered in this thesis: In which AI use cases can Sales and CRM be improved? How can Customer Experience be improved with AI-driven CRM?
The present research had compared how Uppsala and Bartlett & Ghoshal (B&G) models explain the internationalization process of the Brazilian pulp producer Fibria.
The Uppsala model describes the developments of capabilities that enable the firm to move towards higher commitments abroad. Despite its sine-qua-non dependence on foreign markets, it is unlikely that Fibria will internationalize its production to another country, given the country-specific advantages that the company has in Brazil. Nevertheless, Fibria set its structure abroad even when the direct exports would suffice to reach the markets without any foreign direct investment.
B&G deals with the aspects of the organizational structure and described the Transnational type as the evolution of the international firm. In their typology, Fibria was a Global and Ethnocentric type, but interestingly, elements of Transnational and Geocentric models were also observed in the company.
Both theories overlap or complement each other in many aspects. However, they could not explain the peculiarities of the internationalization of Fibria. One reason is the lack of country-related elements in these models.
Eventually, comparisons between theories such as those presented enable decision-makers to align the corporate strategy using suitable models, bearing in mind the limitations that each method entails.
A novel calorimetric technique for the analysis of gas-releasing endothermic dissociation reactions
(2020)
The master thesis concentrates on two different cases to generate energy from MSW. In the first case, the MSW is incinerated in an incineration plant. This approach represents the present situation in the waste treatment in large parts of the UK.
In the second case, the OFMSW is separated in a treatment facility and used in a fermentation plant. The remaining waste is again used as a feedstock in an incineration plant. The difference in the net energy yield between these two cases is investigated in this thesis.
To calculate the difference in the energy yield of case 1 and case 2, a research of the existing literature about comparisons of incineration and fermentation plants and their results are reflected and data about the MSW in the UK is collected. With the input of the literature and the researched data, a model is built which compares the two different cases of waste treatment. The results of the comparisons are then examined by varying different parameters. This step is repeated by using different input parameters. Afterwards, the results are compared and analysed.
In the next part of the thesis, an economic analysis of the incineration and fermentation combined technology plant is made. In this analysis, the investment costs, the annual profits and the annual costs of an additional fermentation plant are discussed and calculated. The result of the analysis is displayed as an amortization time calculation. The results are then analysed by varying the parameters in a sensitivity analysis.
Finally, the research question is answered and a forecast for possible plant designs with an incineration and a fermentation plant in combination are discussed.
In the residential construction industry, the focus on energy efficiency and cost effectiveness has been gaining importance. In order to achieve these contradicting objectives, a shift towards a reduced complexity in building practices can be observed.
Within the HVAC sector, the Tempering method for space heating has received particular attention as an alternative way to heat museums and buildings worthy of preservation.
In spite of the simplified design, this space heating system is claimed to offer significant advantages in its present field of application.
This study evaluates the implementation of Tempering in the residential context. So far, there is no scientific research on the implementation of Tempering in energy efficient-dwellings.
This master thesis provides initial results on achievable heat flux values, the impact on heat generation efficiency, the inherent installation costs as well as the particular
consequences in terms of end energy consumption of the building as a whole. The findings are compared to the individual performances of well-established heat emission approaches.
By means of a numerical analysis and a case study on a real-case single-family home, it is found that the heat flux values of Tempering systems suffice for the implementation within buildings, which comply with the low-energy building standard. Comparing radiant walls, radiant floors and radiators, the inherent installation costs are lowest for Tempering and radiant floors. The impact on the end energy consumption depends largely on the utilised heat generation system. With a gas-condensing boiler, Tempering performs equal to the radiant systems. When a ground source heat pump system is installed, however, Tempering performs poorly and accounts for a significantly increased energy consumption. Radiator systems are found to be the most energy-efficient method for space heating in both cases.
In times of global climate change, it is increasingly important to investigate emissions and resource consumption of all machines and, if possible, to improve them. This includes within the transport sector car ferries.
In order to reduce the environmental impacts of car ferries, the electrification has penetrated into this sector, which has led to the world's first fully electric car ferry. One of the most important components to operate this ferry is the energy storage. Not only the battery storage of the ferry itself is needed, but also an onshore battery storage system is needed to support the electrical grid.
The present study examines how storage technologies and concepts can impact the environment considering the world's first all-electric car ferry, MF Ampere, which operates in Norway.
To examine this, the current onshore battery storage system is compared to a concrete sphere storage system. For this purpose, data from the first test run of this new storage technology, which was successfully carried out by the Fraunhofer Institute in 2016, is considered. Subsequently, a life cycle assessment of the two storage systems is carried out to compare the environmental impacts.
The concrete sphere storage system performs better for 15 of 17 impact categories compared to the existing onshore battery storage system. Depending on the impact category the impact reduction is about 2% to 8%.
Nevertheless, it is difficult to estimate how long the useful life and how good the efficiency of the concrete ball storage will be, since no system of this size has been tested yet. Also, the costs of the concrete sphere storage system have not been considered.
In this thesis the effect of dc voltage bias on the equivalent series resistance (ESR) of capacitors and especially ferroelectric dielectric ceramic capacitors (FDCC) is analysed. Further the influence of the dc biased ESR on the losses of capacitors is investigated. Also piezoelectric resonances (PR) occurring in FDCCs with applied dc bias and their influence on the losses are analysed.
Therefore a measurement circuit to measure the impedance and thus the ESR of capacitors in combination with a vector network analyser (VNA) is developed. Using the developed circuit the ESR of capacitors of different technologies is measured and their behaviour with dc bias is evaluated. The losses of an FDCC are measured in a power electronic (PE) circuit with a developed calorimetric measurement system (CMS). The influence of the PR is investigated by tuning the switching frequency of the PE system and thus the frequency of the capacitor current exactly into the PR. The measured losses are then compared to a calculation based on the capacitor current harmonics and the respective ESR.
The measurements show an increase of the ESR with dc bias for all measured FDCCs. The loss measurements show a significant increase of the losses in an FDCC if the current frequency matches the PR frequency. Consequently a decrease of the PE system's efficiency is measured. The loss calculations do not exactly match the measurements but there is a systematic deviation of the same order for all measurements.
