Das vorliegende Buch behandelt lineare zeitdiskrete Regelverfahren und gliedert sich in zwei Teile mit ganz unterschiedlichen thematischen Schwerpunkten. In den ersten sechs Kapiteln steht die Analyse und Synthese von zeitdiskreten Regelungen im Bildbereich im Vordergrund. Im zweiten Teil des Buchs werden im Zeitbereich angesiedelte zeitdiskrete Reglerentwurfsverfahren behandelt. Dort dominieren Zustandsraumverfahren die Erläuterungen.
Diese Bachelorarbeit analysiert das Medienkonsumverhalten der deutschen Bevölkerung und die vielfältigen Nutzungen von YouTube. Mit dieser Abhandlung sollte es möglich sein, wichtige Punkte für die Erstellung eines eigenen YouTube-Kanals zu sammeln. Dies gilt sowohl für Ersteller von Inhalten als auch für Unternehmen.
Zu Beginn wird analysiert, welche Funktionen YouTube für Content Creator, Unternehmen und Konsumenten bietet. Des Weiteren werden die verschiedenen Finanzierungsmöglichkeiten aufgezeigt, welche die Videoplattform anbietet.
Die für die Analyse erforderlichen Daten stammen aus verschiedenen Studien zum Verhalten des Medienkonsums. Darüber hinaus werden auf sozialen Plattformen eigene Umfragen durchgeführt, um einen spezifischen Überblick über die Nutzung von YouTube und seinen Alternativen zu erhalten.
Mit dem Ergebnis der Analyse wird ein Prozess entwickelt, der dazu beitragen soll, Fehler beim Erstellen eines YouTube-Kanals zu vermeiden und einen positiven Effekt für den Kanal zu erzielen. Dieser Prozess enthält wichtige Punkte, die beim Ausführen eines Kanals zu beachten sind.
Wow, You Are Terrible at This!: An Intercultural Study on Virtual Agents Giving Mixed Feedback
(2020)
While the effects of virtual agents in terms of likeability, uncanniness, etc. are well explored, it is unclear how their appearance and the feedback they give affects people's reactions. Is critical feedback from an agent embodied as a mouse or a robot taken less serious than from a human agent? In an intercultural study with 120 participants from Germany and the US, participants had to find hidden objects in a game and received feedback on their performance by virtual agents with different appearances. As some levels were designed to be unsolvable, critical feedback was unavoidable. We hypothesized that feedback would be taken more serious, the more human the agent looked. Also, we expected the subjects from the US to react more sensitively to criticism. Surprisingly, our results showed that the agents' appearance did not significantly change the participants' perception. Also, while we found highly significant differences in inspirational and motivational effects as well as in perceived task load between the two cultures, the reactions to criticism were contrary to expectations based on established cultural models. This work improves our understanding on how affective virtual agents are to be designed, both with respect to culture and to dialogue strategies.
With economic weight shifting toward net zero, now is the time for ECAs, Exim-Banks, and PRIs to lead. Despite previous success, aligning global economic governance to climate goals requires additional activities across export finance and investment insurance institutions. The new research project initiated by Oxford University, ClimateWorks Foundation, and Mission 2020 including other practitioners and academics from institutions such as Atradius DSB, Columbia University, EDC, FMO and Offenburg University focuses on reshaping future trade and investment governance in light of climate action. The idea of a ‘Berne Union Net Zero Club’ is an important item in a potential package of reforms. This can include realigning mandates and corporate strategies, principles of intervention, as well as ECA, Exim-Bank and PRI operating models in order to accelerate net zero transformation. Full transparency regarding Berne Union members’ activities would be an excellent starting point. We invite all interested parties in the sector to come together to chart our own path to net zero
Additive manufacturing (AM) or 3D printing (3DP) has become a widespread new technology in recent years and is now used in many areas of industry. At the same time, there is an increasing need for training courses that impart the knowledge required for product development in 3D printing. In this article, a workshop on “Rapid Prototyping” is presented, which is intended to provide students with the technical and creative knowledge for product development in the field of AM. Today, additive manufacturing is an important part of teaching for the training of future engineers. In a detailed literature review, the advantages and disadvantages of previous approaches to training students are examined and analyzed. On this basis, a new approach is developed in which the students analyze and optimize a given product in terms of additivie manufacturing. The students use two different 3D printers to complete this task. In this way, the students acquire the skills to work independently with different processes and materials. With this new approach, the students learn to adapt the design to different manufacturing processes and to observe the restrictions of different materials. The results of these courses are evaluated through feedback in a presentation and a questionnaire.
Künstliche Intelligenz gilt immer noch als eine der zukunftsweisenden Technologien, die viele Bereiche wie etwa Medizin, Handel, Verkehr und öffentliche Verwaltung revolutioniert. So scheint es nicht verwunderlich, dass bereits knapp jedes fünfte Unternehmen in Deutschland zurzeit KI-Systeme implementiert oder zumindest ihren Einsatz plant. Besonders hoch im Kurs stehen KI-Projekte, um Daten zu analysieren. Ganze 70 Prozent der Unternehmen sehen hier das größte Potenzial, so die Ergebnisse einer Umfrage von PWC [1]. Dennoch lauern einige Stolpersteine, wollen Unternehmen intelligente Datenprojekte umsetzen. Welche Hürden auftauchen können und wie sich diese meistern lassen, erläutert dieser Artikel anhand eines KI-Projektes zur Analyse von Geschäftspartnerdaten [2].
This paper describes a comparative study of two tactile systems supporting navigation for persons with little or no visual and auditory perception. The efficacy of a tactile head-mounted device (HMD) was compared to that of a wearable device, a tactile belt. A study with twenty participants showed that the participants took significantly less time to complete a course when navigating with the HMD, as compared to the belt.
