A convolution algorithm that takes into account electron-density inhomogeneity was recently introduced to calculate dose distributions for the [gamma knife] treatment planning program. The accuracies of the dose distributions computed using the convolution method were assessed using an anthropomorphic phantom and film dosimetry.  2, record 1, English, - convolution%20algorithm

Safety of nuclear plants under normal operating conditions depends on a full knowledge of the relationship between reactivity and neutron flux. … a C. P.

Les méthodes de perturbation ont joué un rôle important en physique des réacteurs depuis les débuts des applications de l’énergie nucléaire, notamment dans le domaine des expériences critiques et des mesures. Déjà Wigner en 1945 en proposait la formulation plus élémentaire, la CPT (Classical Perturbation Theory, théorie classique des perturbations), issue directement des concepts classiques de la mécanique quantique, pour mesurer le poids en réactivité de petits échantillons de matériaux introduits dans une pile atomique. Dans les premières années du développement du nucléaire civil, les méthodes de perturbation occupèrent une place très importante dans les analyses de sûreté car, en raison des moyens de calcul très limités, les études étaient généralement effectuées dans l’approximation à zéro dimension, moyennant l’utilisation de coefficients de sensibilité obtenus justement à l’aide de la méthode CPT.  1, record 3, French, - th%C3%A9orie%20classique%20des%20perturbations

One of numerous parallel surfaces of bedding or foliation which indicate directional properties in rock [and] may be warped.  3, record 4, English, - s%2Dsurface

Workers on petrofabrics correlate s-surfaces of all kinds with deforming movements, but do not attempt anything more than a very broad correlation with deforming forces. They have shown that several sets of schistosity-surfaces may originate in a single deformation (as Becker insisted), though it is also possible for a second schistosity to be superposed upon s-planes of an earlier deformation.  2, record 4, English, - s%2Dsurface

There is considerable confusion in the prevalent usage of terms such as schistosity, foliation, flow cleavage, fracture cleavage, etc., Sander... recommends the employment of a purely descriptive non-genetic term to cover the parallel fabrics of metamorphic rocks; he includes all such structures("sets of planes of mechanical inhomogeneity") in his term "s-surfaces"("s-planes").  2, record 4, English, - s%2Dsurface
