Non-Iterative Ring Beam Shaping Using Phase Control in Coherent Beam Combining [PDF]
EPJ Web of ConferencesWe propose a deterministic method for ring-shaped beam synthesis in coherent beam combining (CBC) systems using phase-only control. A calibrated propagation operator is inverted via a Tikhonov-regularized pseudoinverse to directly compute the required ...

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization
Advanced Engineering Materials, EarlyView.Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...
