Making Cluster Applications Energy-Aware

Dejan Kostic, Nedeljko Vasic, Vincent Salzgeber, Martin Barisits

Power consumption has become a critical issue in large scale clusters. Existing solutions for addressing the servers' energy consumption suggest ``shrinking'' the set of active machines, at least until the more power-proport-ional hardware devices become a ...

Using Augmentations as Bridges from Concrete to Abstract Representations

Pierre Dillenbourg, Patrick Jermann, Guillaume Zufferey

We describe a pedagogical approach supporting the acquisition of abstraction skills by apprentices in logistics. Apprentices start with a concrete representation in the form of a small-scale model which aims at engaging them in learning activities. Multipl ...

Magnetic-Field-Induced Soft-Mode Quantum Phase Transition in the High-Temperature Superconductor La1.855Sr0.145CuO4: An Inelastic Neutron-Scattering Study

Henrik Moodysson Rønnow, Joël Mesot, Johan Juul Chang

Inelastic neutron-scattering experiments on the high-temperature superconductor La1.855Sr0.145CuO4 reveal a magnetic excitation gap Delta that decreases continuously upon application of a magnetic field perpendicular to the CuO2 planes. The gap vanishes at ...
