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} } @masterthesis{Hartwig2017, type = {Bachelor Thesis}, author = {Hartwig, Patrick}, title = {Characterization of Physical and Fluid Dynamical Properties of Residual Biomass in Colombia for Gasification in a Fluidized Bed Reactor}, address = {Brandenburg an der Havel}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-18775}, school = {Technische Hochschule Brandenburg}, year = {2017}, abstract = {Kurzdarstellung Kolumbien ist ein agrarwirtschaftlich gepr{\"a}gtes Land, indem eine Vielzahl verschiedener landwirtschaftlicher Produkte, wie zum Beispiel Zuckerrohr, Kaffee oder Reis, angebaut werden. Durch die j{\"a}hrlich anwachsende Menge an produzierten G{\"u}tern steigt auch die j{\"a}hrlich produzierte Menge an landwirtschaftlichen Abf{\"a}llen, welche Anwendung als erneuerbare Energietr{\"a}ger finden k{\"o}nnen. 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.

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} } @article{GarzonGilIngabireKibathi2023, 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}, 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.

The Meclib concept mitigates this complexity and allows for efficient bulk production of material with consistent appearance and user experience. The core of Meclib is a set of pre-defined JSXGraph-based objects with an interface to Maxima, such that no problem specific JS code is required at all.
