For a solid evaluation of the performance of Mobile Ad-Hoc Networks (MANET), a sound knowledge of the channel characteristics and a suitable channel model to recreate those are essential. This work presents the results of extensive channel measurements in the VHF and UHF band. Based on the results, a well-adapted channel model incorporating the correlation of the links in the network is developed and validated.
Social work as a democratically constituted profession committed to human rights is currently facing cross-border encroachments and attacks by right-wing populist movements and governments. With the Bundestag elections in September 2017, the question of the extent to which right-wing populist forces succeed in influencing the discourse with xenophobic and nationalist arguments arises in Germany, too. The authors examine how social work can respond effectively to nationalism, exclusion, de-solidarization and a basic skepticism about science and position itself against this background. The book explores different conditions in Germany, France, Poland, Russia and the US.
