In this paper, we transform a PERT network into a mixtures of truncated exponentials Bayesian network. We use the Shenoy-Shafer architecture to propagate the MTE potentials in the resulting MTE PERT Bayes net and thus to find the marginal distribution of the project completion time. Finding the distribution of the project completion time is important because there is no closed form expression f...

The paper deals with investigating approximation abilities of a special class of discrete-time dynamic neural networks. The networks considered are called locally recurrent globally feed-forward, because they are designed with dynamic neuron models which contain inner feedbacks, but interconnections between neurons are strict feed-forward ones like in the well-known multi-layer perceptron. The ...

As mobile data traffic increases, and the number of services provided by the mobile network increases, service load flows as well, which requires changing in the principles, models, and strategies for media transmission streams serving to guarantee the given nature of giving a wide scope of services in Flexible and cost-effective. Right now, the fundamental question remains what number of netwo...

In this paper, a new method for developing a lower bound on exact completion time distribution function of stochastic PERT networks is provided that is based on simplifying the structure of this type of network. The designed mechanism simplifies network structure by arc duplication so that network distribution function can be calculated only with convolution and multiplication. The selection of...

in order to have better insight of project characteristics, different kinds of fuzzy analysis for project networks have been recently proposed, most of which consider activities duration as the main and only source of imprecision and vagueness, but as it is usually experienced in real projects, the structure of the network is also subject to changes. in this paper we consider three types of imp...

BACKGROUND Integrating newly developed tests and treatments for severe pulmonary embolism (PE) into clinical care requires coordinated multispecialty collaboration. To meet this need, we developed a new paradigm: a multidisciplinary Pulmonary Embolism Response Team (PERT). In this report, we provide the first longitudinal analysis of patients treated by a PERT. METHODS Our PERT includes speci...
