In the current implementation a sequence of ***random hinges***, where each hinge may extend over multiple voxels, is applied until the ion energy reaches an energy threshold.

variável aleatória


Explanation:
Encontrei este método relacionado ao algoritmo de Monte Carlo. Esses documentos fala de um método chamado "random hinge", que foi traduzido neste outro documento como método de "variável aleatória".

----------
Em Inglês

One idea is to split the total distance s to be traveled in each step into two substeps of lengths ξs and (1 – ξ)s, where the number ξ is chosen at random 0 and 1. This random hinge method (see, for example, papers by Kawrakow and Bielajew [5] and Fernandez-Varea et al. [4]) can be shown (see Larsen [13]) to increase the accuracy in CH modeling. However, even these improved algorithms suffer ultimately from the lack of exact knowledge of the spatial distribution of radiation. Of equal importance for the computational success of such models, special strategies are often needed in order to deal with model inaccuracies near abrupt changes in material properties and at external boundaries, adding further to the cost of their implementation.

Em Português

O método de Monte Carlo (MMC) pode ser descrito
como um método estatístico, no qual se utiliza uma sequência de números aleatórios para a realização de uma
simulação (...) Outra componente fundamental em processos estocásticos é o conceito de variável aleatória. Qualquer
quantidade que não pode ser especificada sem o uso
das leis de probabilidade é chamada de variável aleatória.

ja que isso tem a ver com uma maquina, hinge so pode ser dobradica. Tipo aquelas dobradicas de porta mesmo. Entao" random hinges" seria dobradicas aleatorias,
