This paper describes the development of a proof-of-concept application, which can be used to train people in the field of programmable logic controller (PLC) and robot programming. This concept leads to a better understanding, what kind of infrastructure and software packages can be combined, to not only have a visual representation of an industrial like scenario, but also the possibility to use commonly established programming environments such as TIA Portal, to set up a PLC program. In addi-tion, it provides insights on how OPC UA can be used and is suitable for controlling a typical six-axis industrial robot with the help of a PLC.

Die Industrie ist im Wandel. Die Grenzen zwischen Industrien, Anwendungsbereichen und Unternehmen verschwinden immer weiter, sind teils kaum noch in ihrer alten Ausprägung zu erkennen. Auch die industrielle Automation kann und sollte sich diesem Trend nicht entziehen. Immer mehr Technologien und Paradigmen anderer Bereiche gewinnen an Bedeutung. Hinzu kommt, dass die Anzahl und die Vielfalt an Geräten, Anwendungen, Anforderungen und Technologien stetig wächst. Diese Arbeit befasst sich mit Ansätzen, die es ermöglichen, einigen Aspekten der wachsenden Komplexität zu begegnen. Dabei handelt es sich um Technologien und Konzepte zum Thema Management, genauer zum Netzwerk-, System- und Dienste-Management. Ziel ist es nicht nur einen Ansatz zu finden, der gegenwärtigen Ansprüchen genügt, sondern auch noch für kommende Entwicklungen geeignet ist.

The bilingual Tanzanian writer William Eliezer Mkufya was born on the 18th of June 1953 in Tanga region. Mkufya is a self-trained writer as he had a scientific education. Ua la Faraja (The flower of consolation) won the TEPUSA best manuscript award in 2001 and was published in 2004. it is supposed to be the first part of the trilogy Maua (Flowers) in which the author commits himself to the fight against the plague of AIDS in the context of the existentialist philosophy. In more than 400 pages he presents several persons affected by this frightening disease and even if no one recovers his or her health, the author did not sink into pessimism, but presents a sign of hope, or rather a `flower of consolation`. Mkufya returns with Ua la Faraja to the realistic novel, assuming the traditional role of a teacher. Although his main concern is to convey a message explaining how to face the calamity that is affecting Africa more severely than any other part of the world, he has achieved it with an anti-melodramatic approach and with great skill.

Economic utilization of geothermal networks under agricultural surfaces needs large agricultural areas. In order to exploit the cultivated land more effectively, this paper proposes a novel locally vibrating plough system that employs a hydraulic actuator direct on the plough blade instead of the state of the art external vibration units. Starting with a description of geothermal networks under agricultural surfaces and the construction technology in details, the contribution shows different concepts, the development and test of the most promising solution for imprinting local vibrations at the cutting edge with the goal of traction force reduction. A virtual demonstrator, the test rig set-up and the control concepts are described. Both of the closed-loop simulation and experimental position control of the entire vibration system demonstrate that the novel design has impressive performance improvement. Finally, the integration of the vibration system into a prototype tool is shown and the reduction of the traction force is proven by experiments carried out with a tractor on a testing field.

We argue that this action mediating impacted considerably in the negotiations between the republic of Sudan and the republic of South Sudan, since: (i) it was established a ceasefire in hostilities between the warring parties, especially in the border regions between the two Sudanese states; (ii) an active effectiveness on the part of the peacekeeping operations of the UN and AU to ensure civilian protection and humanitarian aid in face of escalating violence in the region; (iii) the establishment of the most significant agreements regarding the outstanding issues, especially regarding the creation of a demilitarized zone in Abyei. First, we discussed International Mediation Theory in Post-Cold War Era to clarify its main assumptions, thus considering the importance of mediation in solving international crises, taking as a basis the various types mediators. Then we carried out a descriptive presentation of the case study, the conflict in Southern Sudan, seeking to discuss the implications of the Comprehensive Peace Agreement (CPA) and its subsequent implementation in 2005. In this case, we sought to emphasize issues related to wealth distribution, delimitation of borders and sovereignty of Abyei. Finally, we examined the mediating role of the UN and the AU, as a means of conflict resolution, facing these outstanding issues arising from the CPA in 2011- 2012. To do so, we pointed up its successes and failures in driving this conflict mediation process and the maintenance of peace in warring areas. Given the above, we point the central question of this study: what is the level of effectiveness of the UN and the AU as mediating institutions in building and promoting peace in South Sudan? Before the points raised, we argued that mediation effectiveness could be observed in terms of humanitarian impact on the region, actions issued by the UN Security Council and the African Peace Council in curbing violence in the States of Jonglei and Abyei. Therefore, this dissertation is structured based on qualitative analytical, exploratory and descriptive research on issues of Conflict Resolution, International Mediation, and Regional and International Organizations. / Esta dissertação tem como objetivo debater a efetividade do papel mediador da Organização das Nações Unidas (ONU) e da União Africana (UA) na resolução do conflito do Sudão do Sul. Argumenta-se que essa atuação mediadora impactou de forma considerável nas negociações entre a república do Sudão e a república do Sudão do Sul, uma vez que: (i) percebeu-se um cessar-fogo nas hostilidades entre as partes beligerantes, especialmente, nas regiões fronteiriças entre os dois Estados sudaneses; (ii) uma ativa efetividade, por parte das operações de paz da ONU e UA, em assegurar a proteção civil e a ajuda humanitária em face da escalada da violência na região; (iii) o estabelecimento de acordos mais significativos em relação às questões pendentes, principalmente no que se referiu à criação de uma Zona Desmilitarizada em Abyei. Discute-se, inicialmente, o estudo com uma compreensão teórica acerca da Mediação Internacional no pós-Guerra Fria visando a esclarecer suas principais premissas. Considerando-se a importância da mediação na resolução de crises internacionais, tomaram-se por base os variados tipos de mediadores. Em seguida, passou-se para a apresentação descritiva do caso prático, o conflito do Sudão do Sul, buscando-se discutir as implicações do Acordo Geral de Paz (CPA) e sua posterior implementação, em 2005. Nesse caso, procuraram-se ressaltar as questões relacionadas à partilha das riquezas, a delimitação das fronteiras e a soberania da região de Abyei. Por fim, analisou-se o papel mediador da ONU e da UA, enquanto meios de resolução de conflitos, frente a essas questões pendentes, resultantes do CPA, no biênio 2011-2012. Para tanto, apontou-se seus acertos e falhas na condução do processo de mediação desse conflito e na manutenção da paz nas áreas beligerantes. Diante do exposto, volta-se para a pergunta central desse estudo: qual a efetividade da ONU e da UA, como instituições mediadoras, na construção e promoção da paz no Sudão do Sul? Frente aos pontos levantados, argumenta-se que a efetividade da referida mediação pôde ser constatada em termos do impacto humanitário no terreno, das ações emanadas pelo Conselho de Segurança da ONU e pelo Conselho de Paz Africano em conter a violência nos Estados do Jonglei e Abyei. Portanto, esta dissertação se estrutura à luz da pesquisa qualitativa-analítica, exploratória e descritiva sobre os temas da Resolução de Conflitos, da Mediação Internacional e das Organizações Regionais e Internacionais.

This thesis details the design of a protocol translator between the industrial-automation protocol OPC UA, and HTTP. The design is based on the architecture of the protocol translator of the Arrowhead framework, and is interoperable with all of its associated protocols. The design requirements are defined to comply with a service-oriented architecture (SOA) and RESTful interaction through HTTP, with minimal requirement of the consuming client to be familiar with OPC UA semantics. Effort is put into making translation as transparent as possible, but limits the scope of this work to exclude a complete semantic translation. The solution presented in this thesis satisfies structural- and foundational interoperability, and bridges interaction to be independent of OPC UA services. The resulting translator is capable of accessing the content of any OPC UA server with simple HTTP-requests, where addressing is oriented around OPC UA nodes.

Internet of Things (‘IoT’) systems are complex, asynchronous solutions often comprised of various software and hardware components developed in isolation of each other. These components function with different degrees of reliability and performance over an inherently unreliable network, the Internet. Many IoT systems are developed within silos that do not provide the ability to communicate or be interoperable with other systems and platforms. Literature exists on how these systems should be designed, how they should interoperate, and how they could be improved, but practice does not always consult literature. The work brings together a proposed reference architecture for the IoT and engineering practices for flow semantics found in existing literature with a commercial implementation of an IoT platform. It demonstrates that the proposed IoT reference architecture and flow-service-quality engineering practices when integrated together can produce a more robust system with increased functionality and interoperability. It shows how such practices can be implemented into a commercial solution, and explores the value provided to the system when implemented. This work contributes to the current understanding of how complex IoT systems can be developed to be more reliable and interoperable using reference architectures and flow semantics. The work highlights the value of integration of academic solutions with commercial implementations of complex systems.
