In this TDP we describe a new tool created for testing the strategy layer of our soccer playing agents. It is a complete 2D simulator that simulates the games based on the decisions of 22 agents. With this tool, debugging the decision and strategy layer of our agents is much more efficient than before due to various interaction methods and complete control over the simulation.
In the future, the tool could also serve as a measure to run simulations of game series much faster than with the 3D simulator. This way, the impact of different play strategies could be evaluated much faster than before.
Automatic Identification of Travel Locations in Rare Books - Object Oriented Information Management
(2017)
The digital content of the Internet is growing exponentially and mass digitization of printed media opens access to literature, in particular the genre of travel literature from the 18th and 19th century, which consists of diaries or travel books describing routes, observations or inspirations. The identification of described locations in the digital text is a long-standing challenge which requires information technology to supply dynamic links to sources by new forms of interaction and synthesis between humanistic texts and scientific observations.
Using object oriented information technology, a prototype of a software tool is developed which makes it possible to automatically identify geographic locations and travel routes mentioned in rare books. The information objects contain properties such as names and classification codes for populated places, streams, mountains and regions. Together, with the latitudes and longitudes of every single location, it is possible to geo-reference this information in order that all processed and filtered datasets can be displayed by a map application. This method has already been used in the Humboldt Digital Library to present Alexander von Humboldt’s maps and was tested in a case study to prove the correctness and reliability of the automatic identification of locations based on the work of Alexander von Humboldt and Johann Wolfgang von Goethe.
The results reveal numerous errors due to misspellings, change of location names, equality of terms and location names. But on the other hand it becomes very clear that results of the automatic object detection and recognition can be improved by error-free and comprehensive sources. As a result an increase in quality and usability of the service can be expected, accompanied by more options to detect unknown locations in the descriptions of rare books.
Technology and computer applications influence our daily lives and questions arise concerning the role of artificial intelligence and decision-making algorithms. There are warning voices, that computers can, in theory, emulate human intelligence-and exceed it. This paper points out that a replacement of humans by computers is unlikely, because human thinking is characterized by cognitive heuristics and emotions, which cannot simply be implemented in machines operating with algorithms, procedural data processing or artificial neural networks. However, we are going to share our responsibilities with superior computer systems, which are tracking and surveying all of our digital activities, whereas we have no idea of the decision-making processes inside the machines. It is shown that we need a new digital humanism defining rules of computer responsibilities to avoid digital totalism and comprehensive monitoring and controlling of individuals within the planet Earth.
Qualitative Wissenschaft, künstlerisches Forschen und forschendes Lernen verbinden Erkenntnis aus Praxis und Erfahrung. In der Autoethnographie der eigenen Werkstatt des Hörens wie der Kultur in Studios anderer, wird die noch neue Interdisziplin Sound (Studies) erprobt und vertieft, mit Impulsen für die Praxis und Theorie, von der noch wenig bekannten A/r/t ographie heute, hin zu einer künftig A/R/Tophonie, dem künstlerischen Forschen in der Musik, ebenso wie durch Klang Komposition, Radio Kunst und visuelle Musik.
Objective: This paper deals with the design and the optimization of mechatronic devices.
Introduction: Comparing with existing works, the design approach presented in this paper aims to integrate optimization in the design phase of complex mechatronic systems in order to increase the efficiency of this method.
Methods: To solve this problem, a novel mechatronic system design approach has been developed in order to take the multidisciplinary aspect and to consider optimization as a tool that can be used within the embodiment design process to build mechatronic solutions from a set of solution concepts designed with innovative or routine design methods.
Conclusions: This approach has then been applied to the design and optimization of a wind turbine system that can be implemented to autonomously supply a mountain cottage.
Im vorliegenden Beitrag wird ein Strommarktsimulationsmodell entwickelt, mit dessen Hilfe die Bereitstellung von Flexibilität auf dem Strom- und Regelleistungsmarkt in Deutschland modell-gestützt analysiert werden soll. Das Modell bildet dabei zwei parallel verlaufende, zentrale Wettbewerbsmärkte ab, an denen Akteure durch die individuelle Gebotsermittlung handeln können. Die entsprechend hierzu entwickelte Gebotslogik wird detailliert erläutert, wobei der Fokus auf der Flexibilität fossil-thermischer Kraftwerke liegt. In der anschließenden Gegen-überstellung mit realen Marktpreisen zeigt sich, dass die verwendete Methodik und die Ge-botslogik den bestehenden Markt und dessen Marktergebnis in geeigneter Form wiederspie-geln, wodurch zukünftig unterschiedlichste Flexibilitätsszenarien analysiert und Aussagen zu deren Auswirkungen auf den Markt und seine Akteure getroffen werden können.
Kinder am Bildschirm
(2017)
Wenn in Studien über digitale Medien und Kinder berichtet wird, liegt der Fokus meist darauf, Kinder „fit für die digitale Zukunft“ zu machen. Welche Folgen eine zu frühe und nicht regulierte Nutzung von Bildschirmmedien bei Kindern und Jugendlichen haben kann, zeigt sich in den Praxen der Kinderärzte. Das Spektrum der zu behandelnden Erkrankungen und der Beratungsbedarf bei psychosozialen Problemen haben sich in den letzten Jahren grundlegend verändert, schreiben die Verantwortlichen der BLIKK-Studie.
The electrical field (E-field) of the biventricular (BV) stimulation is important for the success of cardiac resynchronization therapy (CRT) in patients with cardiac insufficiency and widened QRS complex.
The aim of the study was to model different pacing and ablation electrodes and to integrate them into a heart model for the static and dynamic simulation of BV stimulation and HF ablation in atrial fibrillation (AF).
The modeling and simulation was carried out using the electromagnetic simulation software CST. Five multipolar left ventricular (LV) electrodes, four bipolar right atrial (RA) electrodes, two right ventricular (RV) electrodes and one HF ablation catheter were modelled. A selection were integrated into the heart rhythm model (Schalk, Offenburg) for the electrical field simulation. The simulation of an AV node ablation at CRT was performed with RA, RV and LV electrodes and integrated ablation catheter with an 8 mm gold tip.
The BV stimulation were performed simultaneously at amplitude of 3 V at the LV electrode and 1 V at the RV electrode with a pulse width of 0.5 ms each. The far-field potential at the RA electrode tip was 32.86 mV and 185.97 mV at a distance of 1 mm from the RA electrode tip. AV node ablation was simulated with an applied power of 5 W at 420 kHz at the distal ablation electrode. The temperature at the catheter tip was 103.87 °C after 5 s ablation time and 37.61 °C at a distance of 2 mm inside the myocardium. After 15 s, the temperature was 118.42 °C and 42.13 °C.
Virtual heart and electrode models as well as the simulations of electrical fields and temperature profiles allow the static and dynamic simulation of atrial synchronous BV stimulation and HF ablation at AF and could be used to optimize the CRT and AF ablation.
