Bayesian networks (BNs) have become an essential tool for reasoning under uncertainty in complex models. In particular, the subclass of Gaussian Bayesian networks (GBNs) can be used to model continuous variables with Gaussian distributions. Here we focus on the task of learning GBNs from data. Factorization of the multivariate Gaussian joint density according to a directed acyclic graph (DAG) p...

A quasi-independence result holds for the go-back-n automatic repeat request (ARQ) protocol and the sliding window ow control protocol if packet errors are independent. The result is independent of the magnitude of the packet error probability or the cost of an error. A parallel result for the selective repeat ARQ protocol, however, does not appear to hold. Parts of this paper were presented as...

OBJECTIVE To describe the anthropometric and physical performance characteristics of a sample of senior A club rugby players and to highlight differences between the positional categories of the players within the forwards and backs. METHODS 94 senior A male rugby players were assessed on a number of anthropometric and physical performance assessments. The forwards were categorised into props...

We propose a new type of ubiquitous decision support system that is powered by a General Bayesian Network (GBN). Because complicated decision support problems are plagued by complexities when interpreting causal relationships among decision variables, GBNs have shown excellent decision support competence because of their flexible structure, which allows them to extract appropriate and robust ca...

Article history: Received 18 October 2015 Received in revised form 25 January 2016 Accepted 17 February 2016 Available online 23 February 2016 Editor: M. Cvetič The non-relativistic versions of the generalized Poincaré algebras and generalized AdS-Lorentz algebras are obtained. These non-relativistic algebras are called, generalized Galilean algebras of type I and type II and denoted by GBn and...

A new variant of the selective-repeat protocol is presented. While the protocols used until now have been based on cumulative acknowledgments and a single retransmit timer, a protocol based on individual acknowledgments and a separate timer for each outstanding packet is proposed here. In spite of a slightly increased complexity of the proposed protocol, when comparing it to the basic selective...

results the results showed that the highest compressive force exerted on the back was equal to 4002 n and the lowest force 1425 n. moreover, 76% of the tasks were reported to have the highest compressive force greater than the recommended limit; 72% of the tasks had an li 1 - 3 and 28% of them had an li less than 1. there was a weak direct correlation between compressive force and rwl. backgrou...

In this paper, an ARQ Go-Back-N protocol with time-out mechanism is studied. Transmissions on both the forward and the reverse channels are assumed to be subject to Markovian errors. A recently developed approach, based on renewal theory, is further extended and the steady state average number of packets in the ARQ system is evaluated. This allows us to determine analytically both throughput an...
