A continuous curve M will be said to be a two-way continuous curve, or to be "two-way continuous," provided it is true that between every two points of M there exist in M at least two arcs neither of which is a subset of the other. A point P of a continuum M is a cut point of M provided it is true that the point set M—P is not connected. Every point of a continuum M which is not a cut point of ...

The performance of external sorting using merge sort is highly dependent on the length of the runs generated. One of the most commonly used run generation strategies is Replacement Selection (RS) because, on average, it generates runs that are twice the size of the memory available. However, the length of the runs generated by RS is downsized for data with certain characteristics, like inputs s...

In this paper we study two-way min-plus automata. We prove that two-way distance automata are equivalent to one-way distance automata. In the second part of the paper we show that, with general min-plus semirings, it is decidable whether every accepted word has a weight different from −∞ and that, in contrast, it is undecidable whether there exists a word accepted with a weight different from −∞.

In 1991, Luka and ten of his comrades were captured near Knin, a Croatian town held by rebel Serbs and the Yugoslav Federal Army. Luka spent a few months in the Knin jail. The first days he was left without food or water. He kept refusing to submit himself to the guards, so they would often take him to the top floor and beat him until he would pass out. After-wards, they would drag him down, hi...

General-to-speci c learners like ID3 and CN2 perform well when the target concept descriptions are general, but often have di culties when they are speci c or mixed. This problem can be alleviated by combining them with a speci c-to-general learning component, resulting in a two-way induction system. In this paper one design for such a component is proposed, as well as two methods for combining...

We present a meshless simulation method for multiphase fluid-particle systems using Smoothed Particle Hydrodynamics (SPH) and the Discrete Element Method (DEM). Rather than fully resolving the interstitial fluid, which is often infeasible, we use an unresolved fluid model based on the locally averaged Navier Stokes equations. A variable-h SPH formulation is used to calculate the fluid phase, wh...

UNLABELLED We present and review coupled two-way clustering, a method designed to mine gene expression data. The method identifies submatrices of the total expression matrix, whose clustering analysis reveals partitions of samples (and genes) into biologically relevant classes. We demonstrate, on data from colon and breast cancer, that we are able to identify partitions that elude standard clus...
