    Informell und formal Lernen in CoPs
    (FH Joanneum, 2018-09-13)
    ;
    Fallmann, Irmgard 
    ;
    Im Poster wird darstellt, wie informelles und formales Lernen – zwei recht unterschiedliche Lernformen – im Online Distance Learning an einer Hochschule miteinander in Berührung kommen. CoPs bieten hier Möglichkeiten zwischen den beiden Lernformen zu vermitteln – denn wir wollen das implizite Erfahrungslernen der Studierenden, ihr Vorwissen, berücksichtigen und im Studium darauf aufbauen und individuelle Lernwege ermöglichen. In CoPs kann implizites Wissen, das oft aus informellem Lernen wie etwa Erfahrungslernen resultiert, rasch und einfach geteilt werden. Dies passiert implizit oder durch Externalisation (Nonaka & Takeushi 1996), etwa durch die Schaffung von Artefakten, die auf der gemeinsamen Praxis basieren. Damit trifft eine informelle Komponente auf eine formelle Komponente, das Informelle kann durch die Externalisierung formalisiert werden, das implizite Erfahrungslernen dadurch auch etwa im formalen Lernen an der Hochschule eingebunden werden.

    Remote On-Screen Support and Cooperation with Open Sporce Components in e-Learning
    (E. Weber, 2008)
    In many learning situations it is essential to offer support for the students by an instructor directly at the computer screens of the students like in a computer lab. To provide this support in remote e-learning situations, the teacher needs a real-time view of the contents of the students computer screen from remote. in this paper we discuss a solution for providing real-time remote on-screen student support with distance-learning via internet connections in a safe and secure manner. Our "virtual classroom" consists of open source components only and workson most operating systems independently of the underlying learning software used. We enhance this solution with a prototype of a common desktop, that is suitable for small work groupsto work together on a common computer screen in real time, which is useful e.g. for small student groups working togetherfrom remote. The common desktop systemalso works independently of the software used on the screen and can be operated with any client computer. In practice, these solutions are accompanied by commuication systems like chat or voice-chat, to achieve a system for real-time remote teaching and real-time remote cooperation.

    Neue Perspektiven für E-Portfolios
    (EDU|days, 2017-04-06)
    E-Portfolios als digitale Sammelmappen für Arbeitsergebnisse, Reflexion und Kommentare werden oft eingesetzt. In den meisten Fällen wird dabei das Werkzeug Mahara genutzt. In dieser "traditionellen" Variante sind die E-Portfolios primär für die Autoren und Lehrenden sichtbar. Am Masterstudiengang Angewandtes Wissensmanagement haben wir uns für eine neue Variante der E-Portfolio-Umsetzung entschieden. Seit zwei Jahren arbeiten die Studierenden mit WordPress E-Portfolios, die im Internet frei zugänglich sind. Damit sind nicht nur technische und organisatorische Herausforderungen verbunden. Die Studierenden müssen vor allem ihre Kompetenzen in den Bereichen Content Management Systeme, Webdesign, Textgestaltung, Medienrecht und persönliches Wissensmanagement "live" im Internet anwenden.

    Podcasting-based Mobile Learning in Blended Learning Courses
    (ICL 2009 International Conference Interactive Computer Aided Learning, 2009-09-26)
    Blended learning scenarios benefit from educational content delivered to mobile devices supporting full mobility of students. Podcasting and the utilization of various types of podcasts are discussed as an efficient means of providing mobile students in a part-time degree programme with learning content. Crucial to the success of podcasting is the chosen course design that mixes face-to-face phases with distance learning phases based on the delivery of appropriate content embedded in podcasting episodes. The type and output format of those episodes has to be chosen accurately according to the applied usage scenario.

    A Security Cost Modelling Framework for Cyber-Physical Systems

    Cyber-Physical Systems (CPS) are formed through interconnected components capable of computation, communication, sensing and changing the physical world. The development of these systems poses a significant challenge since they have to be designed in a way to ensure cyber-security without impacting their performance. This article presents the Security Cost Modelling Framework (SCMF) and shows supported by an experimental study how it can be used to measure, normalise and aggregate the overall performance of a CPS. Unlike previous studies, our approach uses different metrics to measure the overall performance of a CPS and provides a methodology for normalising the measurement results of different units to a common Cost Unit. Moreover, we show how the Security Costs can be extracted from the overall performance measurements which allows to quantify the overhead imposed by performing security-related tasks. Furthermore, we describe the architecture of our experimental testbed and demonstrate the applicability of SCMF in an experimental study. Our results show that measuring the overall performance and extracting the security costs using SCMF can serve as basis to redesign interactions to achieve the same overall goal at less costs.

    An Algorithm to Transform an Artificial Neural Network into its Open Equation Form and its Potential Applications
    (North Atlantic University Union, 2015)
    During the last decades artificial neural networks have evolved to an accepted and proven technology for modelling and function approximation. Different kinds of network architectures exist to support certain domains and applications in an efficient way. This paper assumes the traditional multilayer feedforward artificial neural network (ANN) architecture with one input layer, one or more fully interconnected hidden layers and one output layer. Each layer consists of several classic perceptron nodes using a differentiable transfer function like the logistics function. Very often it is useful to have an ANN model in an open equation form available, that allows a deeper analysis of the model and to do more complex experiments and simulations. The following paper presents an algorithm that makes it possible to transform an ANN into its open form equivalent, called process model architecture network or PMA network. It has been used as an integral part in several industrial control projects. A PMA network can be used for system simulation, scenario analyses or inverse model based control. An example application is discussed.
