The prompt neutron and γ emission from primary fission fragments are calculated for thermal neutron induced fission of 235U and 239Pu and for spontaneous fission of 252Cf using a Monte Carlo Hauser-Feshbach approach for the evaporation of the excited fission fragments. Remaining free model parameters, such as excitation energy sharing and initial spin distribution, are determined by comparison ...
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
utilization of effective instruments in support of and to provide economic safety for active population in the agricultural sector and towards an increase in production is an indispensable necessity. agricultural crop insurance is one of these instruments. the purpose of this paper is to investigate the factors affecting an adoption of agricultural crops’ insurance among apple growers in semiro...
KNO scaling, i.e. the collapse of multiplicity distributions Pn onto a universal scaling curve manifests when Pn is expressed as the distribution of the standardized multiplicity (n− c)/λ with c and λ being location and scale parameters governed by leading particle effects and the growth of average multiplicity. At very high energies, strong violation of KNO scaling behavior is observed (pp̄) an...
A new approach for multiplicity control (Optimal Subset) is presented. It is based on the selection of the best subset of partial (univariate) hypotheses which, when combined, produce the minimal p-value. The second step consists in multiplicity adjustment. In this work we show how to perform this new procedure in the permutation framework, choosing adequate combining functions and permutation ...
the purpose of this letter is to revisit the nonlinear reaction-diusion modelin porous catalysts when reaction term is fractional function of the concen-tration distribution of the reactant. this model, which originates also in uidand solute transport in soft tissues and microvessels, has been recently givenanalytical solution in terms of taylors series for dierent family of reactionterms. we...
I compare the numerical multiplicity function given in Yahagi, Nagashima & Yoshii (2004) with the theoretical multiplicity function obtained by means of the excursion set model and an improved version of the barrier shape obtained in Del Popolo & Gambera (1998), which implicitly takes account of total angular momentum acquired by the proto-structure during evolution and of a non-zero cosmologic...
In this paper, we prove a multiplicity result for some biharmonic elliptic equation of Kirchhoff type and involving nonlinearities with critical exponential growth at infinity. Using some variational arguments and exploiting the symmetries of the problem, we establish a multiplicity result giving two nontrivial solutions.
Gluon dominance model is proposed to study multiparticle production. This model describes multiplicity distributions in e+e−, pp̄ annihilation and pp interactions.
Many kinds of interactions among individuals construct collective animal behavior, but how to apply this multiplicity of interactions is often unclear when constructing models. We propose multiplicity of interaction in a simple model constructed from three factors: asynchronous updating, learning site patterns, and agent anticipation. We found that the first two contribute to an efficient searc...
