The Great Shutdown

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 academic paper will analyze the current economic ties between Taiwan and other countries, as well as the potential consequences of a disruption in trade and production caused by a military conflict. The research will also examine the role of Taiwan's microchip industry in the global supply chain and its potential vulnerability to a disruption in the event of a military escalation. Additionally, this scientific paper will explore the possible economic responses of other countries and the international community to a military escalation of the China-Taiwan conflict. The research will use a combination of the systematic literature review and the scenario technique to demonstrate potential impact of a military escalation of the China-Taiwan conflict on global economies, with a specific focus on the microchip production industry in Taiwan.

The purpose of this work is to demonstrate how International Transport of Nuclear Material in Brazil is organized, coordinated and executed according to the National Nuclear Security Regime. 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.
Diese Arbeit gibt einen Einblick sowie eine Einschätzung eines Code-basierten
Werkzeuges zur Datenvisualierung, der d3js bibliothek für JavaScript. Es
werden nicht nur das Potential, sondern auch die Vor- und Nachteile evaluiert.
Weiterhin wird eine Einschätzung gegeben, wann der Einsatz dieses Werkzeuges
sinnvoll ist. Um diese Einschätzungen treffen zu können, werden einige Di-
agramme, bezüglich der aktuellen Flüchtlichgssituation, die aufgrund des
bewaffneten Ukrainekonfilktes besteht, erstellt. Dafür werden zunächst die
nötigen Grundlagen erklärt. Dies umfasst sowohl Daten und Datentypen,
als auch Diagramme und deren Aufbau. Abschließend werden die erstellten
Diagramme, sowie d3js im Diskussionsteil ausgewertet.
Da d3js in reinem JavaScript implementiert ist, lässt es sich problem-
los mit anderen Frameworks kombinieren. Der Fokus von d3js liegt auf der
schnellen und einfachen Manipulation von Elementen im Document Object
Model. d3js ist jedoch kein Werkzeug, mit dem in wenigen Zeilen Quell-
code ganze Diagramme erstellt werden können. Vielmehr müssen sowohl die
einzelnen Elemente eines Diagrammes, wie auch deren Position und Ausse-
hen händisch definiert werden. Das ermöglicht ein Höchstmaß an Kontrolle
über das Aussehen und Verhalten der Diagramme. Es ist jedoch auch zeitin-
tensiv und führt eventuell zur Implementation unübersichtlicher Diagramme.
Gepaart mit der hohen initialen Lernkurve kann die Nutzung von d3js nur
in speziellen Fällen, welche die volle Kontrolle über Aussehen und Verhalten
von Diagrammen benötigen, empfohlen werden.
The Quantum Threat looms over cryptography: Once strong quantum computers become available, its game over for encryption and privacy. This widespread understanding of the how cryptography will be impacted by quantum computing is challenged in this thesis to achieve a more nuanced understanding of both the ramifications of the Quantum Threat and potential countermeasures to it.
Single dielectric microspheres can manipulate light focusing and collection to enhance optical interaction with surfaces. To demonstrate this principle, we experimentally investigate the enhancement of the Raman signal collected by a single dielectric microsphere, with a radius much larger than the exciting laser spot size, residing on the sample surface. The absolute microsphere-assisted Raman signal from a single graphene layer measured in air is more than a factor of two higher than that obtained with a high numerical aperture objective. Results from Mie’s theory are used to benchmark numerical simulations and an analytical model to describe the isolated microsphere focusing properties. The analytical model and the numerical simulations justify the Raman signal enhancement measured in the microsphere-assisted Raman spectroscopy experiments.
