El proyecto consiste en el desarollo de un conjunto de módulos software para implantar un sistema lógico difuso. En un caso particular este sistema se aplica a las plantas del laboratorio de Ingeniería de Sistemas y Automática de la E.T.S.I. Industriales de la Universidad de Valladolid. El número de profesores implicados ha sido de 5, todos ellos de dicho departamento. El software ha sido desarrollado empleando la herramienta Borland Builder C++.

En esta investigación se elabora y propone un método de análisis automático de actitudes ambientales que se aplica a la construcción de test de parejas de imágenes ambientales. Estos test reúnen dimensiones o escalas independientes de las predisposiciones del público ante los paisajes y otros aspectos del medio ambiente.. Se emplean 680 parejas de fotografías de escenas de comportamientos ambientales, para analizar las dimensiones fundamentales de las actitudes infantiles ante el entorno. En el trabajo se encuentran hasta seis dimensiones incorreladas relacionadas con distintas posibilidades de comportamiento. Se observa en este estudio que las escalas que se obtienen del análisis automático de actitudes ambientales son sensibles a cambios producidos en el transcurso de una actividad de educación ambiental y también a diferencias intergrupales en la apreciación del medio ambiente.. Entre las aplicaciones del método desarrollado, además de la educación ambiental, destacan la interpretación del medio y la planificación ambiental en las áreas relativas a la percepción de la calidad de vida..

A simple and most promising oxide-assisted catalyst-free method is used to prepare silicon nitride nanowires that give rise to high yield in a short time. After a brief analysis of the state of the art, we reveal the crucial role played by the oxygen partial pressure: when oxygen partial pressure is slightly below the threshold of passive oxidation, a high yield inhibiting the formation of any silica layer covering the nanowires occurs and thanks to the synthesis temperature one can control nanowire dimensions

This study investigates the relation between physical measurements of pure-tones, third-octave bands of noise and third-octave bands of speech and subjective judgments of auditory threshold, most-comfortable listening level (MCL) and uncomfortable-listening level (UCL) for three normally hearing listeners.

This paper discusses a study undertaken to determine whether a normal hearing person or hearing impaired person can reliably select a threshold of intelligibility and if so, whether this can be considered a valid measurement.

This paper investigates loudness summation in a group of listeners with moderate to severe hearing losses and the applicability of this information to hearing aid fittings.

This paper is a review of a study to evaluate the usefulness of a laboratory approach to auditory training with hearing impaired children.

This paper presents some normative data on the relation between the perceived loudness of third-octave bands of noise and that of broad-band noise. The study used normally-hearing listeners and was used as a control study for a parallel study done with hearing impaired listeners.

The primary objective of this research study is to determine if various body positions for ocular vestibular evoked myogenic potential (oVEMP) testing demonstrate differentiation of the saccule and utricle through threshold responses.

Two types of ecological thresholds are now being widely used to develop conservation targets: breakpoint-based thresholds represent tipping points where system properties change dramatically, whereas classification thresholds identify groups of data points with contrasting properties. Both breakpoint-based and classification thresholds are useful tools in evidence-based conservation. However, it is critical that the type of threshold to be estimated corresponds with the question of interest and that appropriate statistical procedures are used to determine its location. On the basis of their statistical properties, we recommend using piecewise regression methods to identify breakpoint-based thresholds and discriminant analysis or classification and regression trees to identify classification thresholds.
