Additives and polymer composition influence the interaction of microplastics with xenobiotics
(2021)
In Industry 4.0 machine learning approaches are a state-of-the art for predictive maintenance, machine condition monitoring, and others. Distributed decision trees are one of the learning algorithms for such applications. A new approach of node based parallelization for the construction is presented and allows to classify data through a network of nodes. Attacks on the nodes are discussed based on different attack scenarios and attack classifications are presented. A thorough analysis of protection measurements is given, such that classification is not maliciously modified by an attacker. Different countermeasures are proposed and analyzed. A quorum-based system allows for a good balance between computational overhead and robustness of the algorithm.

Biosynthesis of iron oxide magnetic nanoparticles using clinically isolated Pseudomonas aeruginosa
(2021)
Distributed machine learning algorithms that employ Deep Neural Networks (DNNs) are widely used in Industry 4.0 applications, such as smart manufacturing. The layers of a DNN can be mapped onto different nodes located in the cloud, edge and shop floor for preserving privacy. The quality of the data that is fed into and processed through the DNN is of utmost importance for critical tasks, such as inspection and quality control. Distributed Data Validation Networks (DDVNs) are used to validate the quality of the data. However, they are prone to single points of failure when an attack occurs. This paper proposes QUDOS, an approach that enhances the security of a distributed DNN that is supported by DDVNs using quorums. The proposed approach allows individual nodes that are corrupted due to an attack to be detected or excluded when the DNN produces an output. Metrics such as corruption factor and success probability of an attack are considered for evaluating the security aspects of DNNs. A simulation study demonstrates that if the number of corrupted nodes is less than a given threshold for decision-making in a quorum, the QUDOS approach always prevents attacks. Furthermore, the study shows that increasing the size of the quorum has a better impact on security than increasing the number of layers. One merit of QUDOS is that it enhances the security of DNNs without requiring any modifications to the algorithm and can therefore be applied to other classes of problems.
Training of neural networks requires often high computational power and large memory on Graphics Processing Unit (GPU) hardware. Many cloud providers such as Amazon, Azure, Google, Siemens, etc, provide such infrastructure. However, should one choose a cloud infrastructure or an on premise system for a neural network application, how can these systems be compared with one another? This paper investigates seven prominent Machine Learning benchmarks, which are MLPerf, DAWNBench, DeepBench, DLBS, TBD, AIBench, and ADABench. The recent popularity and widespread use of Deep Learning in various applications have created a need for benchmarking in this field. This paper shows that these application domains need slightly different resources and argue that there is no standard benchmark suite available that addresses these different application needs. We compare these benchmarks and summarize benchmarkrelated datasets, domains, and metrics. Finally, a concept of an ideal benchmark is sketched.
Potentials of Semantic Image Segmentation Using Visual Attention Networks for People with Dementia
(2021)
Due to the increasing number of dementia patients, it is time to include the care sector in digitization as well. Digital media, for example, can be used on tablets in memory care and have considerable potential for reminiscence therapy for people with dementia. The time consuming assembly of digital media content has to be automated for the caretakers.
This work analyzes the potentials of semantic image segmentation with Visual Attention Networks for reminiscence therapy sessions. These approaches enable the selection of digital images to satisfy the patients individual experience and biographically. A detailed comparison of various Visual Attention Networks evaluated by the BLEU score is shown. The most promising networks for semantic image segmentation are VGG16 and VGG19.
In edge/fog computing infrastructures, the resources and services are offloaded to the edge and computations are distributed among different nodes instead of transmitting them to a centralized entity. Distributed Hash Table (DHT) systems provide a solution to organizing and distributing the computations and storage without involving a trusted third party. However, the physical locations of nodes are not considered during the creation of the overlay which causes some efficiency issues. In this paper, Locality aware Distributed Addressing (LADA) model is proposed that can be adopted in distributed infrastructures to create an overlay that considers the physical locations of participating nodes. LADA aims to address the efficiency issues during the store and lookup processes in DHT overlay. Additionally, it addresses the privacy issue in similar proposals and removes any possible set of fixed entities. Our studies showed that the proposed model is efficient, robust and is able to protect the privacy of the locations of the participating nodes.

Kartographierung ethischer Sollbruchstellen : Schleichender Wertewandel und neue Vulnerabilitäten
(2021)
Das Ziel der vorliegenden Arbeit war es zu prüfen, inwiefern der Entwurf des deutschen Sorgfaltspflichtengesetzes für den Schutz der Menschenrechte und Umweltstandards wirksam und notwendig ist. Das Forschungsthema wurde anhand der Textilindustrie beleuchtet. Es wurden internationale Standards, Richtlinien und Vereinbarungen näher betrachtet. Des Weiteren wurden die menschenrechtlichen Sorgfaltspflichten und die Inhalte des Entwurfes für ein allgemeines Grundverständnis evaluiert. Die Arbeit analysierte die Lieferkettengesetze im Ausland und alternative Maßnahmen. Durch Experteninterviews mit Unternehmen aus der Textilbranche wurden neue Erkenntnisse gewonnen. Die Ergebnisse der Arbeit zeigten, dass freiwillige Maßnahmen nur eine eingeschränkte Wirksamkeit haben, da nicht alle Unternehmen verpflichtet werden und die Maßnahmen nicht rechtsbindend sind. Jedoch helfen freiwillige Maßnahmen in der Regel dabei, die menschenrechtliche Sorgfaltspflicht und den Entwurf des deutschen Sorgfaltspflichtengesetzes einzuhalten. Grundsätzlich hängt die Wirksamkeit eines Lieferkettengesetzes von der inhaltlichen Ausgestaltung ab. Viele der Auswirkungen des deutschen Sorgfaltspflichtengesetzes sind weitestgehend ungeklärt und werden sich erst nach der Einführung des Gesetzes zeigen. Es wurde festgestellt, dass Lieferkettengesetze mit Sanktionen, wie Geldstrafen und Klagemöglichkeiten meist verstärkt eingehalten werden.
Das an der Hochschule Furtwangen University angebotene Outdoor-Wildwassertraining (WWM-Seminar) verknüpft die Managementlehre mit dem Kajakfahren auf dem Wildwasser. Studierende können dieses mehrtägige Wahlpflichtfach freiwillig belegen, nehmen an Theorieeinheiten teil und erfahren sowie erproben das Gelernte auf dem Wildwasserfluss. In der vorliegenden Arbeit wird anhand einer Studie überprüft, welche Auswirkungen das WWM-Seminar auf die Management Skills der Studierenden hat. Dafür wurden Teilnehmende (Testgruppe) sowie Nicht-Teilnehmende (Kontrollgruppe) des Trainings mithilfe eines Fragebogens im Pretest-Posttest-Design befragt. Die Auswertungen der Daten durch analytische Statistik zeigen signifikante Verbesserungen der Einschätzungen der Teilnehmenden bezüglich ihrer Managementfähigkeiten und-fertigkeiten. Lernerfolge durch das WWM-Seminar können angenommen werden.
Abstract
With the writing of this paper, I have the intention to move the legal entity further into the public discourse and test the hypothesis whether the legal entity in its current form is still contemporary. The principle of separability combined with the economic principle is offering much potential to exploit the current economic landscape. Although they are partly constrained by several laws. This cause frictions between governments and corporations. In the following, this paper will show you different ways how companies such as Nestlé, Ikea, or E.ON use the legal entity to follow the economic principle. Furthermore, this paper will show how professional football clubs uses the legal entity to attract investors and in which manner the German Football Association (DFB) use their status as a non-profit organization. The government is trying to restrain companies with laws and restrictions such as a new form of a class action or regulations that prevent nuclear energy operators from outsourcing liabilities to subsidiaries, which arguing against the initial hypothesis. An important part deals with the justification for the existence and criticism of the legal person. Here, the focus is located on statements beside legal professionals such as Christian Jaag who thinks that the current version of the legal person does not fit to the international tax law. He mentioned as a reason for its existence that without the legal person there would not be a taxation in the country it is located as customers, suppliers or employee may locate somewhere else. Experts outside of jurisprudence rarely comment on the legal person. Economists are silent about it and take it for granted, as it is to their advantage.

This bachelor thesis is dedicated to the topic of insurance in the outdoor sports sector. The range of services offered by personal liability insurances, business liability insurances, association liability insurances and accident insurances were examined. For this purpose, all insurance terms and conditions available or obtainable in spring 2021 by companies organized in the German Insurance Association
(Gesamtverband der Deutschen Versicherungswirtschaft e.V.) were compiled and examined for commonalities and differences. Exclusions, inclusions, and special features by the insurance companies were also considered. The results are presented in a tabular overview. As a result, it was possible to determine that in the case of personal liability insurances, coverage for all types of sports is basically provided by all insurance companies without distinction. Deviations can only be found in the areas of horses/riding, water sports and air sports. Only in this spectrum personal liability insurers each make their own offer, which can clearly distinguish them from their competitors. In the case of business liability, no generalized regulations could be identified, except that the respective business purpose is insured.
Thus, specialized outdoor sports companies or outdoor events of other companies are insured. In conclusion, competition among insurance companies is likely to be most pronounced in business liability insurances. Association liability insurances lag behind these major liability areas because sports associations can obtain coverage from a major insurer. The offers by the insurance companies focus on the purpose of the association and are evaluated individually. With the exception of air sports activities, accident insurances indiscriminately insure all bodily injuries that occur as a result of an accident in a private context in outdoor sports. In general, outdoor sports activities of all kinds are always insured or can be insured through appropriate rate or contract negotiations.
