WebRayon atomique (calculé) Rayon atomique calculé à partir d'une formule fonction du nombre quantique principal n, de la charge effective du noyau et du rayon de Bohr. Le rayon est exprimé en pm (pico mètre = 10 -12 m). Tableau périodique classique. Version large. Webrayon. source ·. [ −] Data-parallelism library that makes it easy to convert sequential computations into parallel. Rayon is lightweight and convenient for introducing parallelism into existing code. It guarantees data-race free executions and takes advantage of parallelism when sensible, based on work-load at runtime.
