The study focuses on two main areas: the weakening of the media and the emergence of "smart dictatorship." The paper examines the ways in which AI can be used to supervise, manipulate, and frustrate the media, thereby weakening its role as a check on government and corporate power. The study also explores how AI technology can be used to create an "omnidirectional monitoring" society, where individuals are constantly monitored and controlled through the use of "panopticon" techniques and "social bots". This can lead to the emergence of a "postdemocratic" society, characterized by growing inequality, dehumanization, and the manipulation of information on online media platforms. The research methodology adopted in the study is qualitative, using expert interviews with three experts who discussed the overall use of AI and its disruptive effects on democracy, such as the creation of fake news, filter bubbles, and algorithm bias. In conclusion, this research highlights the need for increased awareness and regulation of AI technology to ensure its responsible use and to protect democratic values.}, subject = {K{\"u}nstliche Intelligenz}, language = {en} } @misc{Brasche2014, author = {Brasche, Ulrich}, title = {Debt-overhang and ways out}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-9204}, pages = {1 -- 65}, year = {2014}, abstract = {The focus of this paper is legacy debt and ways out of it. It introduces credit, debt and financial stress as a basis for understanding the ongoing financial crisis as well as solutions discussed in politics and media. We clarify why and when debt is too much, and discuss ways of avoiding outright default. The main questions are • What are the basics of debt and related financial problems? • How much debt is too much? • Why and when is default a problem to all of us? • Is there a way out of the current debt crisis? While debt and looming bankruptcy of governments is the focus of media attention, we will not neglect the fact, that households, banks and companies in many countries acquired too much debt as well and are therefore a source of problems of their own right.}, language = {en} } @misc{GarzonGilIngabireKibathi2023, type = {Master Thesis}, author = {Garz{\´o}n Gil, Zahira and Ingabire, Noella Arlette and Kibathi, Patrick}, title = {Disruption of Africa's education systems and economic development due to overpopulation}, doi = {10.25933/opus4-2890}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-28909}, school = {Technische Hochschule Brandenburg}, year = {2023}, abstract = {Education lies at the foot of economic growth and human development. However, an increase in population tends to put a strain on existing education systems, especially in Africa where most countries are characterized by slow economic development, rapid population growth rates and a median age just shy of 20 years. Due to the slow rate of economic growth, many African countries lack the financial capability to provide proper education for their ever-growing populations or even already overpopulated regions, many of which have people who have reached the appropriate school-going age. This leads to a series of disruptive impacts on the education systems resulting in a people who are poorly or improperly educated, and thus are not equipped with the necessary skills required for the vast technical, professional and ever modernizing high-skill job markets such as construction, economic and technical professions, teaching occupations and so on, all of which drive economic growth and development. Therefore, we can see that rapid population growth, if left unchecked, may lead to overpopulation scenarios which could have a negative disruptive impact on education and human development, both of which are important factors necessary for economic growth.

Aufgrund der Tatsache, dass es in weiten Teilen Kolumbiens, gerade in den l{\"a}ndlichen agrarwirtschaftlich gepr{\"a}gten Gebieten, Probleme mit der Energieversorgung gibt, k{\"o}nnten die landwirtschaftlichen Abf{\"a}lle genutzt werden, um vor Ort Energie zu erzeugen und die Entwicklung dieser Regionen zu f{\"o}rdern. Die Forschungsgruppe „Biomass and Optimization of Thermal Systems" (BIOT) der „National University of Colombia" besch{\"a}ftigt sich mit genau diesem Thema. In dem Projekt „Efficient Use of Alternative Carbonaceous Fuels in the Power Generation in Colombia by Implementation of Fluidized Bed Reactors" ist geplant, eine zirkulierende Wirbelschichtanlage zur Vergasung von Biomassepartikeln zu konstruieren. Wirbelschichtreaktoren besitzen hervorragende W{\"a}rmetransporteigenschaften, sowie gute Partikelkontaktraten, welche notwendig f{\"u}r einen thermochemischen Wandlungsprozess sind [1]. Das Ziel des Projektes ist es zu untersuchen, welche der vor Ort anfallenden landwirtschaftlichen Abf{\"a}lle effizient genutzt werden k{\"o}nnen, um Energie durch Vergasungsprozesse unter Anwendung einer Wirbelschichtanlage zu produzieren. Die Auslegung des Wirbelschichtreaktors und die Modellierung des thermochemischen Wandlungsprozesses h{\"a}ngt stark von den physischen und fluiddynamischen Eigenschaften der verwendeten Biomassepartikel ab. Die vorliegende Arbeit besch{\"a}ftigt sich mit der experimentellen Bestimmung der wesentlichen Eigenschaften der Biomassepartikel. Dazu geh{\"o}ren: die Partikelgr{\"o}ßenverteilung, der mittlere Partikeldurchmesser, die Sch{\"u}tt- und Partikeldichte und der Feuchtigkeitsgehalt. Im Weiteren werden Fluidisierungsversuche mit Mischungen aus Quarzsand, welcher als Bettmaterial dient, und verschiedenen zugef{\"u}hrten Mengen an Biomassepartikeln durchgef{\"u}hrt. Dabei werden die charakteristischen Kenngr{\"o}ßen, wie die Lockerungsgeschwindigkeit, und die Art der Fluidisierung bzw. die Art der sich ausbildenden Schicht experimentell ermittelt, um Erkenntnisse dar{\"u}ber zu erlangen, ob die verschiedenen landwirtschaftlichen Abf{\"a}lle erfolgreich fluidisiert werden k{\"o}nnen.}, language = {en} } @book{Kraska2023, author = {Kraska, Martin}, title = {SMath with Maxima}, publisher = {Technische Hochschule Brandenburg}, address = {Brandenburg}, doi = {10.25933/opus4-2949}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-29497}, publisher = {Technische Hochschule Brandenburg}, pages = {87}, year = {2023}, subject = {SMath}, language = {en} } @misc{Kuipers2020, type = {Master Thesis}, author = {Kuipers, Tjerk}, title = {Developing nuclear security related legislative guarantees in licensing mobile Small Modular Reactors}, address = {Brandenburg an der Havel}, doi = {10.25933/opus4-2662}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-26627}, school = {Technische Hochschule Brandenburg}, pages = {56}, year = {2020}, abstract = {Goal of the thesis is to research enhancement of the legislative robustness and its possibilities regarding nuclear security of mobile Small Modular Reactors (SMRs) in The Netherlands to improve the licensing process. SMRs are small Nuclear Power Plants (NPPs) with an electrical power output lower than 300 MWe with specific attributes like modularity and mobility, which is beneficial in serial manufacturing, like simplified design features, so fewer components allows for a higher reliability, like passive safety features, which connotes the behavior of components according to known laws of physics, for instance gravity, and like inherent safety features which are defined by reactor characteristics. Chapter 2 reviews the inherent safety and security features of SMRs and its implications on nuclear safety and nuclear security. Chapter 3 deals with the international nuclear regulatory framework and its applicability towards licensing SMRs. Some IAEA Member States have revisioned their legal structure to optimize an SMR licensing process by applying a graded approach towards nuclear security and safety requirements. In Chapter 4 the Dutch nuclear regulatory framework and its impact on SMR developments related to nuclear safety and security are discussed. Suggestions and recommendations for possible legal adjustments are made. Chapter 5 approaches the harmonization of licensing requirements by proposing a more efficient alternative to the Dutch licensing process for all types of NPPs, including SMRs, as presented in international recommendations. Chapter 6 considers the need for SMRs and an alternative approach to the stakeholder involvement in the Dutch NPP licensing process. Generally nuclear regulatory frameworks mainly focus on licensing conventional NPPs and the corresponding nuclear safety and security requirements and therefore prescribing overshooting regulations. Legal options to gradually approach safety and security requirements are deeply embedded in the Dutch Nuclear Energy Act and corresponding legislation. Combined with legal adjustments as denoted in the conclusions and recommendations, the adjustmenst are not only permittable and justifiable but also legally possible. Therefore, the licensing process of SMRs can be streamlined, establishing a harmonized and robust nuclear regulatory framework creating great opportunities for enriching the energy mix in The Netherlands with SMRs.}, language = {en} } @article{PufalShunBenAmmaretal.2023, author = {Pufal, Jakob and Shun, Hanna and Ben Ammar, Rami and Jeckstadt, Janik and Schultheiß, John}, title = {The Great Shutdown}, doi = {10.25933/opus4-2894}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-28942}, pages = {II, 17, VI Seiten}, year = {2023}, abstract = {This research aims to examine the potential impact of a military escalation of the China-Taiwan conflict on global economies, with a particular focus on the microchip production industry in Taiwan.

The country has created a Nuclear Security governance in the Presidency of the Republic Institutional Security Cabinet, which holds a central role in the System for the Protection of the Brazilian Nuclear Program (Sipron, as the acronym in Portuguese), which has recently established the Nuclear Security Coordination in its structure. This new organization enabled the coordination of all national assets involved in the security of nuclear material during transport. Brazil has extensive dimensions; it occupies roughly half of South America, bordering the Atlantic Ocean and all the subcontinent countries except Ecuador and Chile. This continental country presents huge challenges to the ground transportation of any kind in order to reach neighboring countries. Nevertheless, in 2018, a successful nuclear material transport operation to Argentina was coordinated by Sipron within a length of more than 2.000 Km. Nuclear material was delivered from Resende in the State of Rio de Janeiro to Uruguaiana in the State of Rio Grande do Sul in the border with Argentina. This represents an itinerary farther then the distance between Vienna and Moscow. Various security coordination arrangements were necessary before and during the operation. First of all these arrangements were concerned to the identification of all stakeholders roles and responsibilities with the purpose to achieve the necessary synergy in order to perform the operation jointly. The Design and Evaluation Process Outline (DEPO) methodology was applied and the following tasks were accomplished: transportation conveyance characterization; risk and threat assessment with the support of the national intelligence agency; physical protection design according to a defined threat; law enforcement coordination (Federal Police and State Polices); contingency planning; information security measures; personnel clearances; coordination with highway operators; regulatory compliance; activation of the National Command and Control Joint Center and the State Command and Control Joint Centers; synchronization matrix implementation. The operation proved the importance of liaison in all levels, information sharing and cooperation among the responders. However, the principle of confidentiality application became crucial to restrict access to sensitive information to the minimum necessary. Deterrence was largely employed during the operation to minimize risks. The operation has turned into a successful interagency Case Study with many Best Practices and Lessons Learned.}, language = {en} } @masterthesis{Rothenhaeusler2022, type = {Bachelor Thesis}, author = {Rothenh{\"a}usler, Luis}, title = {d3.js and its potential in data visualization}, doi = {10.25933/opus4-2853}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-28536}, school = {Technische Hochschule Brandenburg}, year = {2022}, abstract = {Diese Arbeit gibt einen Einblick sowie eine Einsch{\"a}tzung eines Code-basierten Werkzeuges zur Datenvisualierung, der d3js bibliothek f{\"u}r JavaScript.
