(cont.) Packing/Covering problems, we prove upper and lower bounds on the adaptivity gap depending on the dimension. We also design polynomial-time algorithms achieving near-optimal approximation guarantees with respect to the adaptive optimum. Finally, we prove complexity-theoretic results regarding optimal adaptive…

This paper presents the automatic extension of TERSEO to other languages,
a knowledge-based system for the recognition and
normalization of temporal expressions, originally developed for
Spanish.

TERSEO was extended to English and Italian through the
automatic translation of the…

Context can be described as the totality of ideas, situations and information that (a) related to, (b) provide the origins for, and (c) influence our response, perspective or judgment of a thing. Design always takes place in a context. However,…

(cont.) members. The experimental program for RC beams involves qualitative and quantitative observation of the changes in the debonding behavior and load capacity of the beams with various configurations of shear and/or flexural strengthening and anchorage conditions in four evolutionary…

Despite recent progress in materials synthesis, there are few materials with narrow pore size distributions and well-defined pore structures in the size range of 100 - 500 A. Materials with pores of 100 - 500 A possess a potential combination…

A pesar del progreso que se realiza en el Procesamiento del Lenguaje Natural (PLN) aún estamos lejos de la Comprensión del Lenguaje Natural. Un paso importante hacia este objetivo es el desarrollo de técnicas y recursos que traten conceptos en…

Virtual laboratories offer many advantages for the teaching of technological subjects, such as flexibility in time-tables and
student access to expensive and limited equipment. However, it is also important to evaluate the acceptability of such
laboratories by the students and…

An automatic disassembly cell requires of a
computer vision system for recognition and localization of
the products and each of theirs components. The detection
of occlusions adds more information to the knowledge base
to identify components and products, and generate…

Background: With the release of openEHR Version 1.0 a common Electronic Health Records (EHR) architecture has been defined to pursue the aim of semantic interoperability of Electronic Health Records. Archetypes as clinical content models play a key role in this…

A survey was carried out in different localities of Rangamati and Bandarban Districts of Bangladesh between 2001 and 2002 to document medicinal plants. A total of 69 medicinal plants under 40 families were documented during this work, which the tribal…
