DL­R­magazine 164 – Rolling out the red car­pet for IS­TAR

A special kind of star is seen behind a curtain on the cover of the latest DLRmagazine. Its name, ISTAR, stands for In-flight Systems and Technology Airborne Research. Its future is clear: gradually expanded and equipped with highly specialised measurement technology, the latest addition to DLR's research aircraft fleet should soon be able to simulate the flight characteristics of any aircraft in flight. In the April issue of the DLRmagazine, you can also expect to meet stars made of flesh and blood, such as Jessika Wichner, the head of the DLR Central Archive. She spends her days preserving the past and present for the future. Our partners in conversation on the subject of aviation also look to the future: atmospheric researcher Sigrun Matthes reports on how non-carbon dioxide effects influence the climate, and Christian Eschmann talks about unmanned aircraft systems and their influence on the air traffic of the future. Our future mobility is also the subject of the article about the Test Field in Lower Saxony. DLR is investigating autonomous driving functions there. Space enthusiasts will get an in-depth look at a 'planetary affair'. What do we know about our planetary neighbour Venus and what we have yet to learn. Although our lives have somewhat been turned around in spring of 2020 and all kinds of things are uncertain, the DLRmagazine brings to you its reports, interviews and news from DLR's research and development … and work on the summer edition is already underway

European cinema: face to face with Hollywood

In the face of renewed competition from Hollywood since the early 1980s and the challenges posed to Europe's national cinemas by the fall of the Wall in 1989, independent filmmaking in Europe has begun to re-invent itself. European Cinema: Face to Face with Hollywood re-assesses the different debates and presents a broader framework for understanding the forces at work since the 1960s. These include the interface of "world cinema" and the rise of Asian cinemas, the importance of the international film festival circuit, the role of television, as well as the changing aesthetics of auteur cinema. New audiences have different allegiances, and new technologies enable networks to reshape identities, but European cinema still has an important function in setting critical and creative agendas, even as its economic and institutional bases are in transition

Deployment Strategies for Protected Long-Reach PON

The mass deployment of ?bre access networks is probably the most important network upgrade strategy for operators over the coming decade. Next generation networks, and in particular the Long-Reach Passive Optical Network (LR-PON) solution, aim to increase long term economic viability and sustainability of Fibre-To-The-Premises (FTTP) deployment. The LR-PON solution achieves this by minimising the number of nodes and the amount of electronic equipment required within the network. Since a LR-PON replaces the metro backhaul network, which is usually a protected part of the network, protecting the long reach part of LRPON network against failures becomes a critical issue that needs to be taken into account. In this paper we introduce a novel protection mechanism that, by spreading the load generated by a node failure over the network, can signi?cantly reduce the overall protection capacity required. We then present a practical FTTP deployment scenario based on our protected LR-PON architecture for a European country. The problem is modeled using Integer Linear Programming and the optimisation results, obtained using a real dataset provided by a national operator, show that a small number of Metro/Core nodes can provide protected connection to FTTP users. By applying a detailed cost model to the outcome of the optimisation we are able to show that our LR-PON deployment strategy that minimises the overall protection capacity, rather than just minimising ?bre distances in the LR-PON, can signi?cantly reduce costs
