Cyber-Sicherheit im Weltraum : Verwundbarkeiten, Angriffsvektoren und Schutzmaßnahmen
Schulze, Matthias - Stiftung Wissenschaft und Politik - 2023
Die IT-Sicherheit von Weltrauminfrastrukturen wird relevanter, während sich zahlreiche Staaten einen neuen Wettlauf um … die IT-Sicherheit im Weltraum definieren; ebenso gilt es, frühzeitig einen Informationsaustausch zwischen Staaten und … Computer Emergency Response Teams zu erwägen. Auch mit "Hacking-Wettbewerben" und gemeinsamen Übungen ließe sich dazu beitragen …

Jamming: A simple introduction
Siemens, Alexander O.N.; van Hecke, Martin - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 20, pp. 4255-4264
physics displayed by a very simple model system for the jamming transition: frictionless, soft spheres at zero temperature and … jamming transition, whenever the confining pressure becomes positive. We highlight some of the remarkable geometrical features … of the zero pressure jamming point and discuss the peculiar mechanical properties of these systems for small pressures. …

Optimizing at the ergodic edge
Boettcher, Stefan; Frank, Martin - In: Physica A: Statistical Mechanics and its Applications 367 (2006) C, pp. 220-230
Using a simple, annealed model, some of the key features of the recently introduced extremal optimization heuristic are demonstrated. In particular, it is shown that the dynamics of local search possesses a generic critical point under the variation of its sole parameter, separating phases of...

Flow and jam of granular particles in a two-dimensional hopper
To, Kiwing; Lai, Pik-Yin; Pak, H.K - In: Physica A: Statistical Mechanics and its Applications 315 (2002) 1, pp. 174-180
The jamming phenomenon of granular flow of mono-disperse disks in a two-dimensional hopper is studied experimentally …. When the opening of the hopper d is small, jamming occurs due to formation of an arch at the hopper opening. The jamming … disk configurations of the arch in the jamming events, the jamming probability can be explained quantitatively using a …

Phase segregation in driven diffusive systems
Braun, O.M. - In: Physica A: Statistical Mechanics and its Applications 357 (2005) 2, pp. 350-355
Driven diffusive models describe an array of atoms in an external periodic potential, when the motion is damped due to energy exchange with the substrate. The systems of this class have wide application in modeling of charge and mass transport in solids. Recently, the driven diffusive models...
