QR codes on curved media facades: Two approaches for inverse distortion based on raytracing and image warping

Abstract: Media facades and other public displays are a common sight in our everyday life. They can be found at various places, such as shopping malls or traffic hubs, e.g., the Times Square in New York City or Shibuya Crossing in Tokyo. Thanks to advances in technology, media facades are not bound to plane, rectangular shapes. Thus, many media facades are curved to increase their visual appearance or to better harmonize with the building behind. One example of such a curved media facade is the “Medienfassade” in the city of Munster. The shown content, however, is visually distorted due to the facade's concave shape. That visual distortion may cause problems for certain types of content, i.e., QR codes, that may thus not be scanned with mobile apps. Since QR codes became popular in recent years, it appears desirable to display these codes on curved media facades, too. Thus, we propose two preprocessing approaches to compensate for the visual distortions of the curved media facade. An in-situ evaluation showed that both approaches can be used to “rectify” the distorted QR codes and let them be scanned successfully.

Renditen privater Haushalte nach Vermögensgruppen — Deutschland versus Österreich

Abstract: Sparer mit niedrigen Vermogen leiden unter der Geldpolitik der EZB besonders stark, wird haufig kritisiert. Deshalb untersuchen die Autoren die realen Renditen, die deutsche und osterreichische Haushalte verschiedener finanzieller Vermogensgruppen in Zeiten extrem niedriger Zinssatze erzielen. In allen Gruppen gingen die Renditen zuruck, allerdings weniger deutlich als angenommen. Auserdem zeigt sich, dass reiche Haushalte besonders betroffen sind, auch wenn ihre Renditen heute noch hoher liegen als die armerer Haushalte. Wahrend die allgemeinen Entwicklungen ahnlich sind, ist das Ertragsniveau in Osterreich durchweg niedriger als in Deutschland. Ursache dafur ist vor allem die unterschiedliche Vermogensstruktur. Die Wirtschaftspolitik sollte daher eine hohere Diversifizierung der Vermogenswerte anstreben und dies insbesondere fur armere Haushalte, indem die finanzielle Bildung effektiv verbessert wird.

Large-Eddy-Simulation (LES) Analysis

Abstract: Computational Fluid Dynamics, usually abbreviated as CFD, has become a “third” approach in addition to the classic analytical treatment and the experimental investigation of flow and heat transfer phenomena CFD is a branch of fluid mechanics that uses numerical methods and mathematical algorithms to solve and analyze problems that involve flow phenomena This approach is especially attractive since powerful computers for performing the calculations are now widely available However, the direct numerical simulation (DNS) of turbulent flows resolving the entire range of turbulent length scales at high Reynolds numbers is still not feasible, and appropriate simulation strategies for such flows are still required

Prävention zwischen vorausschauender Unterstützung und normierender Disziplinierung

Abstract: Pravention ist ein Handlungsprinzip Sozialer Arbeit und in der Praxis zentraler Bestandteil konzeptioneller Uberlegungen und Begrundungen. Als Referenz der Kinder- und Jugendhilfe oder der Drogenarbeit wird Pravention von wissenschaftlichen Akteur_innen jedoch auch kritisch beleuchtet. Diese Kritik kann dazu dienen, Situationen einer praventiven Praxis Sozialer Arbeit zu reflektieren, indem sie beispielsweise darauf hinterfragt werden, inwieweit praventive Handlungen als vorausschauende Unterstutzung fur Adressat_innen interpretierbar sind, oder ob sie als normierende oder gar disziplinierende Masnahmen als Politik des Verhaltens kritisiert werden mussen.

Reliable and Energy Optimized Routing Algorithm for WSNs

Abstract: Benefits like elimination of hard-wiring, cost reduction, infrastructure-free and easy maintenance make Wireless Sensor Networks (WSNs) an innovative technology whose range of applications is increasing in many different environments. Since WSNs were born, reliable communications have been a challenge. Some complex routing solutions have been presented in the recent past. In this paper, the objective is to present a simple algorithm to enhance the reliability of end-to-end transmissions optimizing power consumption and to demonstrate that it works in applications that require bounded delay guarantees on packet delivery.
