beryllium chemical combination has a considerable effect on the design and fabrication of the241am9be neutron source. in this investigation the beryllium combinations were studied as a generator ofneutrons with various mass percentage, and the neutron yields were also calculated using the results of thealice and srim codes calculations per unit incident charge. the neutron yields of beryllium ...

‎‎a natural generalization of two dimensional cyclic code ($t{tdc}$) is two dimensional skew cyclic code‎. ‎it is well-known that there is a correspondence between two dimensional skew cyclic codes and left ideals of the quotient ring $r_n:=f[x,y;rho,theta]/_l$‎. ‎in this paper we characterize the left ideals of the ring $r_n$ with two methods and find the generator matrix for two dimensional s...

Comme le laisse entendre la célèbre formule de Lawrence Lessig selon laquelle « code est loi », informatique qu’exécutent les ordinateurs produit des effets régulation sociale. Or, ce lui-même encadré par tout un ensemble standards techniques qui forment une sorte du dont rédaction porteuse nombreux enjeux techno-politiques débattus dans arènes spécialisées. Cet article propose pistes méthodolo...

Recently, flood damage has become a social problem owing to unexperienced weather conditions arising from climate change. An immediate response heavy rain is important for the mitigation of economic losses and also rapid recovery. Spatiotemporal precipitation forecasts may enhance accuracy dam inflow prediction, more than 6 h forward mitigation. However, ordinary ConvLSTM limitation predictable...
