It is widely accepted that deduction, induction and analogy are quite differen forms of reasoning and that is why they are studied separately. We believe tha from a computational point of view deduction, induction and analogy are only slightly different versions of an uniform reasoning process. We shall make an attempt at exploring this process and showing a possible way of reasoning in human p...

As modern computation platforms become increasingly complex, their programming interfaces are increasingly dicult to use. Œis complexity is especially inappropriate given the relatively simple core functionality that many of the computations implement. We present a new approach for obtaining so‰ware that executes on modern computing platforms with complex programming interfaces. Our approach s...

A new type of electronic receiver based on stochastic resonance properties is proposed to retrieve subthreshold modulated (or not) digital signals. In order to check the receiver performances, we investigated different kinds of modulations. Considering both uniform and gaussian white noise, a total restoration of the emitted data is achieved for an unmodulated or amplitude modulated (A.M.) sign...

We report on the use of Perc NCircle atraumatic stone forceps to retrieve stones during laparoscopic ureterolithotomy. We think that it is a safe, simple device and that it has significant advantages over other methods.

The X-ray constrained wavefunction (XC-WF) method proposed by Jayatilaka [Jayatilaka & Grimwood (2001) ▸, Acta Cryst. A57, 76-86] has attracted much attention because it represents a possible third way of theoretically studying the electronic structure of atoms and molecules, combining features of the more popular wavefunction- and DFT-based approaches. In its original formulation, the XC-WF te...

Highly heterogeneous XML collections are thematic collections exploiting different structures: the parent-child or ancestor-descendant relationships are not preserved and vocabulary discrepancies in the element names can occur. In this setting current approaches return answers with low precision. By means of similarity measures and semantic inverted indices we present an approach for improving ...

Indexing cases on features has been shown to be a successful method of retrieving experiential knowledge for many single-task systems. However, discovering a general set of indices for retrieving cross-contextual information in a multi-use knowledge base is impractical. We present a method for retrieving crosscontextuM information based on knowledgedirected spreading activation in a semantic ne...

In this short paper, we present the knowledge representation model called Extended Semantic Network. The basic idea of this proposal is to imagine data representation techniques which can reason beyond the classical techniques in information retrieval systems. It is argued that by employing hybrid techniques one can address the good recall with powerful deduction problems. Our objective here is...

Many programs of bioinformatics provide biochemists and biologists retrieve and analysis services of gene and protein databases. These services access databases for each arrival of user's request, which takes a long time, increases server's overload and response time. In this paper, two data sharing models are presented to reduce database retrieve for sequence alignments. (1) Grouping model is ...

We investigate and compare two forms of recursion on sets for querying nested collections. The rst one is called sri and it corresponds to sequential processing of data. The second one is called sru and it corresponds to data-parallel processing. A uniform rst-order translation from sru into sri was known from previous work. The converse translation is by necessity more diicult and we have obta...
