We present a polynomial time algorithm to find the maximum weight of an edge-cut in graphs embeddable on an arbitrary orientable surface, with integral weights bounded in the absolute value by a polynomial of the size of the graph. The algorithm has been implemented for toroidal grids using modular arithmetics and the generalized nested dissection method. The applications in statistical physics...

Nested Generalized Exemplar (NGE) theory is an incremental form of inductive learning from examples. This paper presents a Fuzzy NGE learning system which induces fuzzy hypotheses from a set of examples described by fuzzy attributes and a crisp class. It presents and discusses the main concepts which supported the development of this system. An empirical evaluation of the FNGE prototype system ...

In order to determine the risk capital for their aggregate portfolio, property and casualty insurance companies must fit a multivariate model to the loss triangle data relating to each of their lines of business. As an inadequate choice of dependence structure may have an undesirable effect on reserve estimation, a two-stage inference strategy is proposed in this paper to assist with model sele...

Analysis of variance (ANOVA) is a statistical procedure for summarizing a classical linear model—a decomposition of sum of squares into a component for each source of variation in the model—along with an associated test (the F-test) of the hypothesis that any given source of variation in the model is zero. When applied to generalized linear models, multilevel models, and other extensions of cla...

Bell’s polynomials are used in many different fields of mathematics, ranging from number theory to operator theory. This paper shows a relevant application probability aimed at computing the moments generalized Gaussian distributions. To this end, table containing first values complete is provided. Furthermore, dedicated code for approximating general distributions terms detailed. Several test ...

This paper describes an execution time estimating model for nested transactions running on locally distributed database systems. At rst the model of nested transactions and the model of a locally distributed database system are established. The performance evaluation model of nested transactions is then built in three steps. The rst step describes a nondeterministic algorithm that evaluates the...

In this concise paper, we present the Nested Relational Sequence Model (NRSM), which is an extension of the Nested Relational Data Model in order to handle XML data. We also introduce a set of algebraic operations pertaining to the Nested Relational Sequence Model, which is an extension of the Nested Relational Data Model in order to handle XML data, to manipulate XML documents via NRS relation...
