The extremely high sensitivity of the Square Kilometre Array (SKA) will make possible Direct-to-Earth (DtE) communications from distant spacecraft within the range of the Solar System. DtE could become a valuable addition to standard communication schemes supporting special science tasks or mission-critical operations. It could also serve as an important back-up option for the “traditional” con...

The system analyzes the data and recognizes if a dangerous situation exists such as the sudden appearance of road construction sites, traffic back-ups and warnings of objects on the road or inclement weather. Drivers are warned of the precise location of the danger through warning lights integrated in the reflector posts and directly via car-to-x communication. Fraunhofer Institute for Embedded...

Compared to divalent ruthenium coordination complexes, which are widely exploited as parts of multi-component photonic devices, optically active trivalent chromium complexes are under-represented in multi-metallic supramolecular architectures performing energy conversion mainly because of the tricky preparation of stable heteroleptic CrIII building blocks. We herein propose some improvements wi...

As a result of globalization, mergers, acquisitions, and scarce skills, software development is increasingly more distributed. Distribution, however, introduces major communication barriers, including time zone differences, cultural differences, and most project participants have not met face to face. In this paper, we focus on “knowledge scouts,” developers that travel briefly to other sites a...

In this paper, we identify two categories of media that are common in computer-supported collaborative learning and software in general: communication media, and information media. These two types of media map easily on to two types of social activities in which learning is grounded: dialogue and monologue. Drawing on literature in learning theory, we suggest the need for interfaces that help s...

Visible light communication (VLC) has largeunlicensed bandwidth, enables communication in radio frequency (RF) responsive environments, understand energy-efficient data transmission, and has the potential to increase the capacity of wireless access networks . On the other hand, WiFi provides more coverage than VLC. In order to take the advantages of both WiFi and VLC, we studied hybrid WiFi-VLC...
