Predictive Analytics als Governance- und Managementanwendung - Zukunftsorientiertes Controlling
(2016)
The aim of the smart grid is to achieve more efficient, distributed and secure supply of energy over the traditional power grid by using a bidirectional information flow between the grid agents (e.g. generator node, customer). One of the key optimization problems in smart grid is to produce power among generator nodes with a minimum cost while meeting the customer demand, known as Economic Dispatch Problem (EDP). In recent years, many distributed approaches to solve EDP have been proposed. However, protecting the privacy-sensitive data of individual generator nodes has been largely overlooked in the existing solutions. In this work, we show an attack against an existing auction-based EDP protocol considering a non-colluding semi-honest adversary. We briefly introduce our approach to a practical privacy-preserving EDP solution as our work in progress.
Practical exercises are a crucial part of many curricula. Even simple exercises can improve the understanding of the underlying subject. Most experimental setups require special hardware. To carry out e. g. a lens experiments the students need access to an optical bench, various lenses, light sources, apertures and a screen. In our previous publication we demonstrated the use of augmented reality visualization techniques in order to let the students prepare with a simulated experimental setup. Within the context of our intended blended learning concept we want to utilize augmented or virtual reality techniques for stationary laboratory exercises. Unlike applications running on mobile devices, stationary setups can be extended more easily with additional interfaces and thus allow for more complex interactions and simulations in virtual reality (VR) and augmented reality (AR). The most significant difference is the possibility to allow interactions beyond touching a screen. The LEAP Motion controller is a small inexpensive device that allows for the tracking of the user’s hands and fingers in three dimensions. It is conceivable to allow the user to interact with the simulation’s virtual elements by the user’s very hand position, movement and gesture. In this paper we evaluate possible applications of the LEAP Motion controller for simulated experiments in augmented and virtual reality. We pay particular attention to the devices strengths and weaknesses and want to point out useful and less useful application scenarios. © (2016) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).

In many scientific studies lens experiments are part of the curriculum. The conducted experiments are meant to give the students a basic understanding for the laws of optics and its applications. Most of the experiments need special hardware like e.g. an optical bench, light sources, apertures and different lens types. Therefore it is not possible for the students to conduct any of the experiments outside of the university’s laboratory. Simple optical software simulators enabling the students to virtually perform lens experiments already exist, but are mostly desktop or web browser based.
Augmented Reality (AR) is a special case of mediated and mixed reality concepts, where computers are used to add, subtract or modify one’s perception of reality. As a result of the success and widespread availability of handheld mobile devices, like e.g. tablet computers and smartphones, mobile augmented reality applications are easy to use. Augmented reality can be easily used to visualize a simulated optical bench. The students can interactively modify properties like e.g. lens type, lens curvature, lens diameter, lens refractive index and the positions of the instruments in space. Light rays can be visualized and promote an additional understanding of the laws of optics. An AR application like this is ideally suited to prepare the actual laboratory sessions and/or recap the teaching content.
The authors will present their experience with handheld augmented reality applications and their possibilities for light and optic experiments without the needs for specialized optical hardware.
UNIKOPS : Universell konfigurierbare Sicherheitslösung für Cyber-Physikalische heterogene Systeme
(2016)
Ziel von UNIKOPS (Universell konfigurierbare Sicherheitslösung für Cyberphysikalische heterogene Systeme) ist es, hochflexible Software- und teilweise auch Hardwarelösungen mit sehr hohem Sicherheitsniveau zu entwickeln, die in einer Vielzahl von CPS-Anwendungsfeldern, insbesondere mit Sensorknoten, einsetzbar sind.
While prospect of tracking mobile devices' users is widely discussed all over European countries to counteract COVID-19 propagation, we propose a Bloom filter based construction providing users' location privacy and preventing mass surveillance.
We apply a solution based on Bloom filters data structure that allows a third party, a government agency, to perform some privacy-preserving set relations on a mobile telco's access logfile.
By computing set relations, the government agency, given the knowledge of two identified persons, has an instrument that provides a (possible) infection chain from the initial to the final infected user no matter at which location on a worldwide scale they are.
The benefit of our approach is that intermediate possible infected users can be identified and subsequently contacted by the agency. With such approach, we state that solely identities of possible infected users will be revealed and location privacy of others will be preserved. To this extent, it meets General Data Protection Regulation (GDPR)requirements in this area.
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.
