In this article we present a generalization of Markov Decision Processes with discreet time where the immediate rewards in every period are not deterministic but random, with the two first moments of the distribution given.Formulas are developed to calculate the expected value and the variance of the reward of the process, formulas which generalize and partially correct other results. We make some observations about the distribution of rewards for processes with limited or unlimited horizon and...
If a regenerative process is represented as semi-regenerative, we derive
formulae enabling us to calculate basic characteristics associated with the first occurrence
time starting from corresponding characteristics for the semi-regenerative
process. Recursive equations, integral equations, and Monte-Carlo algorithms are
proposed for practical solving of the problem.
Un hecho delictivo ha sido cometido por una o más personas. Para descubrir el número de presuntos delincuentes, se determina el perfil genético de la evidencia forense encontrada en el lugar del delito, mediante el estudio de marcadores de tipo STR. En el presente artículo se desarrollan diversos algoritmos. En el primero se considera la probabilidad de que n personas elegidas aleatoriamente de la población de referencia contengan un perfil genético compatible, en el segundo se calcula la evidencia...
Este artículo expone un método para el cálculo del número medio de máquinas en funcionamiento en un sistema formado por un operario y N máquinas iguales, con tiempos exponenciales de funcionamiento entre averías y tiempos de servicio aleatorios, idéntica e independientemente distribuidos. El modelo generaliza las conocidas fórmulas que se obtienen a partir de los modelos M/M/1 con centro emisor finito y de Ashcroft, que suelen utilizarse para el problema de asignación de máquinas.
In this paper we obtain a representation of semimartingalas in the plane by means of stochastic integrals. Some applications to the study of random Markov gaussian fields are given.
On définit les capacités de Choquet dans le cas fini en utilisant une forme bilinéaire non dégénérée associée à la base de Choquet. On montre que, dans le cas fini, une capacité de Choquet est la donnée d’un convexe de mesure qu’on caractérise. Le cas profini, issu des arbres, est obtenu par passage à la limite projective du cas fini. Sur les capacités profinies, on définit une forme bilinéaire dont le rapport avec l’intégration, dans des cas simples, est étudié.
On étudie les espaces de Sobolev construits sur un espace localement convexe muni d’une mesure gaussienne centree . Si est de Radon, on démontre que les capacités naturelles sont tendues sur les compacts. Cela résulte d’un principe général relatif aux quasi-normes.On s’intéresse également aux fonctions quasi-continues a valeurs banachiques, ce qui est utile pour les propriétés de Nikodym, et à des applications à la continuité des trajectoires des intégrales stochastiques.
We study two systems that are based on sums of weakly dependent
Bernoulli random variables that take values ± 1 with equal
probabilities. We show that already one step of the so-called
soft decision parallel interference cancellation, used in the third
generation of mobile telecommunication CDMA, is able to considerably
increase the number of users such a system can host. We also
consider a variant of the well-known Hopfield model of neural
networks. We show that this variant proposed by Amari...
