Total Cost of Ownership (TCO) is a key tool to have a complete understanding of the costs associated with an investment, as it allows to analyze not only the initial acquisition costs, but also the long-term costs related to operation, maintenance, depreciation, and other factors. In the context of the cement industry, TCO is especially important due to the complexity of the production processes and the wide variety of components and machinery involved in the process.
For this reason, a TCO analysis for the cement industry has been conducted in this study, with the objective of showing the different components of the cost of production. This analysis will allow the reader to gain knowledge about these costs, in the industrial model will be to make informed decisions on the adoption of technologies and practices that will allow them to reduce costs in the long run and improve their operational efficiency.
In particular, this study pursues to give visibility to technologies and practices that enable the reduction of carbon emissions in cement production, thus contributing to the sustainability of industry and the protection of the environment. By being at the forefront of sustainability issues, the cement industry can contribute to the achievement of environmentally friendly technologies and enable the development of people and industry.
The Oxyfuel technology has been selected as a carbon capture solution for the cement industry due to its practical application, low costs, and practical adaptation to non-capture processes. The adoption of this technology allows for a significant reduction in CO2 emissions, which is a crucial factor in achieving sustainability in the cement manufacturing process.
Carbon capture storage technologies represent a high investment, although these technologies increase the cost of production, the application of Oxyfuel technology is one of the most economically viable as the cheapest technology per capture according to the comparison. However, this price increase is a technical advantage as the carbon capture efficiency of this technology reaches 90%. This level of efficiency leads to a decrease in taxes for the generation of CO2 emissions, making the cement manufacturing process sustainable.
The COVID-19 pandemic has led to an economic downturn in the Slovak Republic. To bridge corporate liquidity problems the Slovakian Government has introduced several support measures. The investigation discusses the effectiveness of the measures imposed. Based on theoretical foundations, the research question is empirically examined by using a qualitative expert survey. As the automotive industry plays a leading role in Slovakia, the research conducted is oriented towards the financing phases, a typical automotive exporter is undergoing. As a result of the research, bridging loans and government grants were identified as the most important measures. Additionally, tendencies towards political recommendations for action were identified. The research explored, that the Slovakian Government should focus on meeting the short-term liquidity needs, boosting exports and promoting innovation as well as considering a support package for the automotive industry.
The objective of this thesis is the quantification and qualification of neonicotinoid insecticides using thin-layer chromatography (TLC). Neonicotinoids are a relatively new form of pesticides, which have been proven to be extremely lethal to the honey bee, Apis mellifera. In this paper six forms of neonicotinoid insecticides (i.e. Acetamiprid, Thiacloprid, Imidacloprid, Clothianidin, Thaimethoxam, and Nitenpyram) are analysed. The initial steps are to first find a suitable mobile phase eluent, followed by the search for a reagent causing a luminescence effect of the neonicotinoids on a TLC plate. Subsequently, a calibration method is then used to find the detection limit of this TLC experiment. The aim is, therefore, to achieve a standard method of quantifying and qualifying neonicotinoids via TLC. Whilst a suitable mobile phase has been established, an optimal fluorescent reagent has yet to be found and more research on the subject must be carried out.
The research paper provides important findings about the development, difficulties and perception of the support measures for exporters introduced by the Austrian government in times of COVID-19 crisis. Based on a literature review using secondary data, eight qualitative interviews were conducted with experts from the Austrian economy and government, among them the Austrian ECA ‘Oesterreichische Kontrollbank AG’. To balance the effects of the COVID-19 pandemic on the Austrian economy, a broad coverage with financing instruments for a wide range of target groups was established. Although the support measures have been well received by companies, insolvencies cannot completely be prevented. Nevertheless, the actual effects are not yet predictable and need to be assessed in further research at a later point in time.
The COVID-19 pandemic has been spreading rapidly across the globe and has seriously affected global trade. In order to reduce the pandemic’s impact on their economy, the French government released a support plan referring to the COVID-19 crisis. Since mid-tier companies play a leading role in France’s export, this paper deals with the measures taken by the French government to support especially French mid-tier export companies. Based on empirical literature and recent publications, the research question is analyzed by conducting interviews with experts, such as market participants, governmental institutions and an expert for trade and innovation. As a result of the research, the emergency measures taken by the French government, such as the CAP Francexport reinsurance scheme, the extension of cover for export guarantees, additional information and assistance, and the deferral of tax and social security contributions have mitigated the effects at first instance.
The COVID-19 pandemic has the global economy under control. This paper deals with the economic consequences in Germany and shows the measures taken by the German government to support especially small and medium-sized export companies. The structure of the German economy and foreign trade promotion are explained as a basis. After considering the government's support measures, an evaluation of country comparisons shows that there is still potential for further measures, especially in direct lending and debt moratorium. The analysis is based on quantitative data from surveys and qualitative results from interviews with relevant ministries and market participants as well as recent publications.
Decarbonisation Strategies in Energy Systems Modelling: APV and e-tractors as Flexibility Assets
(2023)
This work presents an analysis of the impact of introducing Agrophotovoltaic technologies and electric tractors into Germany’s energy system. Agrophotovoltaics involves installing photovoltaic systems in agricultural areas, allowing for dual usage of the land for both energy generation and food production. Electric tractors, which are agricultural machinery powered by electric motors, can also function as energy storage units, providing flexibility to the grid. The analysis includes a sensitivity study to understand how the availability of agricultural land influences Agrophotovoltaic investments, followed by the examination of various scenarios that involve converting diesel tractors to electric tractors. These scenarios are based on the current CO2 emission reduction targets set by the German Government, aiming for a 65% reduction below 1990 levels by 2030 and achieving zero emissions by 2045. The results indicate that approximately 3% of available agricultural land is necessary to establish a viable energy mix in Germany. Furthermore, the expansion of electric tractors tends to reduce the overall system costs and enhances the energy-cost-efficiency of Agrophotovoltaic investments.
If the current situation could be described in one word, it would be ‘uncertainty’. In times of global crisis, it is important to support the economy to keep businesses alive. Therefore, this paper shows the Finnish government measures and how exporters can benefit from them. Looking in particular at the maritime sector, the research pointed out that there were not that many specific measures for exporters and shipbuilders. This essay detected that the provided measures are suitable for the needs of the affected companies and are an effective instrument by the government to stabilise the industry. This is proved by the number of companies taking advantage of these loans, grants and guarantees. Due to the already mentioned uncertainty, it remains unclear how measures have to be adjusted in the future.
The aim of this essay is to analyse and evaluate the Italian government measures for exporters in response to COVID-19. The unexpected, rapid and hardly predictable consequences of the pandemic paralyzed the entire globe. For a long time, Italy was the epicentre of the virus, which caused severe damage in the Italian export economy dropping temporarily more than 40%. The Italian government reacted exemplary fast and took multiple countermeasures of high extent especially through the Italian export credit agency SACE. On the one hand, the internationally compared broad structure of SACE was a huge advantage, which allowed to release quickly numerous measures. On the other hand, there is room for improvement regarding the accessibility of measure-related information, which has been partially only available in Italian. Furthermore, there is a remarkable risk resulting from the combination of the high monetary effort to enable the numerous measures, the difficult financial situation of the Italian government and the unpredictability of the COVID-19 consequences.
This seminar paper examines government measures to support export-oriented companies in Belgium. After a short overview of the Belgian economy and the impact of the Covid-19 crisis, the paper introduces the available government measures for exporters. In particular, the role of Credendo as a Belgian export-credit insurance company will be discussed, and its measures will be examined in more detail. In addition, federal measures of the Belgian government will be identified, and a summary of the most important regional measures will be provided. The entirety of government measures available to export-oriented companies will be reviewed and options for the future activities of export-oriented companies will be pointed out.
Android is the most popular mobile operating system. Its omnipresence leads to the fact that it is also the most popular target amongst malware developers and other computer criminals. Hence, this thesis shows the security-relevant structures of Android’s system and application architecture. Furthermore, it provides laboratory exercises on various security-related issues to understand them not only theoretically but also deal with them in a practical way. In order to provide infrastructure-independent education, the exercises are based on Android Virtual Devices (AVDs).
In this work, the authors have dealt with the question of what measures have been taken by the Danish government to support exporters during the time of COVID-19. The analysis first looks at Denmark's general economic situation. In the following, Denmark's governmental and financial measures to support exporters are briefly explained. In addition to the economic and financial effects, the issue of green energy has also become a major focus of political attention in times of crisis. Denmark is a pioneer in the wind energy sector and accounts for a large share of exports. For this reason, the impact and possible future developments for the wind sector in connection with the pandemic are also being investigated.
Quarz crystal microbalances allow the monitoring of the adsorption process of mass from a liquid to their surface. The adsorbed mass can be analysed regarding to its protein content using mass spectromety. To ensure the protein identification the results of several measurements can be combined. A high content QCM-D array was developed to allow up to ten measurements parallel. The samples can be routed inside the array distributing one sample to several chips. The fluidic parts were prototyped using 3D printing. The assembled array was tight and the sample routing function could be demonstrated. A temperature controller was developed and implemented. The parameters for the PID controller were determined and the controller was shown to be able to keep the temperature constant over long time with high accuracy.
The coronavirus affects the strongly export-oriented Swiss economy in a situation where political and economic developments are already making the cross-border exchange of goods and services difficult. For this reason, the question arises of how Switzerland can maintain or strengthen its position in global competition in the export business during an unprecedented period of crisis such as the current one.
In order to find an answer to this question, this paper critically examines the existing government support measures for Swiss exporters in times of COVID-19. The fact that Switzerland has so far not taken any specific support measures for exporters raises the actual research question of whether there is a specific necessity and demand for a special export promotion. To answer this research question, various expert opinions are compared and overall conclusions are drawn. By rapidly introducing and adapting the already existing instruments – liquidity assistance and an expansion of short-time work benefits – the federal government was able to ensure the survival of many companies. According to the authors of this paper, this focus of government support in times of crisis is just right for a small national economy in the short term and therefore preferable to a specific support of exporters. Nevertheless, given the high relative importance of foreign trade for Switzerland’s overall economic performance, there can be no recovery of national economy without a recovery of foreign trade.
British Government long-term Measures for Exporters in the Manufacturing Sector in Times of COVID-19
(2020)
The authors of this paper have addressed the question of what measures have been taken by the British government to support exporters in the manufacturing sector in the era of COVID-19. A classification of the manufacturing export industry in the British economy as a whole and the impending economic impact of COVID-19 were also examined. It should be noted that the United Kingdom is facing major structural changes as a result of the Corona pandemic and its withdrawal from the European Union, which are examined more in detail in this paper. The UKEF, in cooperation with other institutions, provides a number of finance facilities for exporters already before Corona crisis. The access to get this support has been facilitated for the COVID-19 affected exporters, but no additional measures were made available.
This essay deals with the Spanish economy and especially with the Spanish governmental measures for SME exporters in times of COVID-19. The focus was set on SMEs, as they are an essential part of trade for the government and are particularly affected by the pandemic. Since the financial crisis, the Spanish economy has become highly diversified, with a greater focus on exports. Competitiveness, productivity and efficiency have increased significantly. The Spanish government measures largely affect the areas liquidity and financing, taxes and protection of the employment. One of the most important measures is the 100-billion-euro credit line and the policies on unemployment. The Spanish government is dependent on further aid packages and is criticized for the measures.
This essay is about Estonia’s measures to help its exporters responding to COVID-19. The purpose is to analyse the companies’ need for help measures and the governmental objectives behind the measures and finally to analyse the possible effects. We used the two latest surveys dealing with the entrepreneurship situation and conducted two inter-views with governmental representatives exposing their objectives. The outcomes show that more than half of Estonian companies are asking for governmental help mainly as a consequence of a drop of demand. Limiting the increase of unemployment and bankrupt-cies as well as strengthening the economic recovery were identified as the main govern-mental objectives while restraining fiscal costs is a subordinated objective but becomes more important the more money will be spent. The help measures offered by KredEx are in line with these objectives. After the crisis the implications of the established measures should be analysed so that others can learn from the Estonian Government’s approach.

In the beginning, there was an idea: the reconstruction of the first "Iron Hand" of the Franconian imperial knight Götz von Berlichingen (1480–1562). We found that with this historical prosthesis, simple actions for daily use, such as holding a wine glass, a mobile phone, a bicycle handlebar grip, a horse’s reins, or some grapes, are possible without effort. Controlling this passive artificial hand, however, is based on the help of a healthy second hand.
Researchers are developing new GNSS receivers and antennas based on an innovative signal-processing scheme to significantly improve GNSS tracking reliability and accuracy under degraded signal conditions. It is based on the principles of synthetic-aperture radar. Like in a multi-antenna phased array receiver, GNSS signals from different spatial locations are combined coherently forming an optimized synthetic antenna-gain pattern. The method is implemented in a real-time PC-based software receiver and works with GPS, GLONASS, and Galileo signals. Multiple frequencies are generally supported. The idea of synthetic-aperture processing is realized as a coherent summation of correlation values of each satellite over the so-called beamforming interval. Each correlation value is multiplied with a phase factor. For example, the phase factor can be chosen to compensate for the relative antenna motion over the beam-forming interval and the resulting sum of the scaled correlation values represents a coherent correlation value maximizing the line of sight signal power.
This thesis explores the feasibility and optimization of a solar-thermal sorption system mainly designed to provide cooling but also capable of heating functionalities. Through the development of a black-box model using Python programming, the study delves into the system's performance under various operation modes. Simulation results reveal the effectiveness of adaptive control strategies and pre-heating stages in optimizing efficiency, particularly in cooling modes. In heating assessments, superior performance is observed when utilizing the outdoor coil as the heat source for the heat pump. Challenges related to operational temperature bands are addressed, proposing parallel connections of the heat pump and outdoor coil to enhance performance. Future research directions include refining regression models and incorporating real-time measurement data for improved accuracy, as well as extending simulation duration for comprehensive evaluations. This study contributes valuable insights into the system’s capabilities and applications, laying the groundwork for advancements in heat-driven integrated sustainable energy systems.
