Protocolo de seguimiento del desarrollo infantil: el entorno educativo de la atenci??n temprana : Plan Marco de Atenci??n Temprana

El Protocolo de Seguimiento del Desarrollo Infanti tiene por objetivo detectar tempranamente posibles alteraciones del desarrollo que puedan generar necesidades espec??ficas de apoyo educativo. Una intervenci??n temprana en los trastornos del neurodesarrollo o en las situaciones de riesgo exige un proceso de detecci??n. En la pr??ctica, y entre otras medidas posibles aunque de menor envergadura, este proceso pasa por la puesta en marcha de procedimientos sistem??ticos de observaci??n del desarrollo para valorar la presencia de sospechas, alertas o indicadores de esos trastornos, adem??s de tener en cuenta situaciones objetivas de riesgo de padecerlos.

Computing Distance Functions from Generalized Sources on Weighted Polyhedral Surfaces

We present algorithms for computing approximate distance functions and shortest paths from a generalized source (point, segment, polygonal chain or polygonal region) on a weighted non-convex polyhedral surface in which obstacles (represented by polygonal chains or polygons) are allowed. We also describe an algorithm for discretizing, by using graphics hardware capabilities, distance functions. Finally, we present algorithms for computing discrete k-order Voronoi diagrams

Generalized Higher-Order Voronoi Diagrams on Polyhedral Surfaces

We present an algorithm for computing exact shortest paths, and consequently distances, from a generalized source (point, segment, polygonal chain or polygonal region) on a possibly non-convex polyhedral surface in which polygonal chain or polygon obstacles are allowed. We also present algorithms for computing discrete Voronoi diagrams of a set of generalized sites (points, segments, polygonal chains or polygons) on a polyhedral surface with obstacles. To obtain the discrete Voronoi diagrams our algorithms, exploiting hardware graphics capabilities, compute shortest path distances defined by the sites

View-dependent information theory quality measures for pixel sampling and scene discretization in flatland

In this paper, we present view-dependent information theory quality measures for pixel sampling and scene discretization in flatland. The measures are based on a definition for the mutual information of a line, and have a purely geometrical basis. Several algorithms exploiting them are presented and compare well with an existing one based on depth differences

Shape complexity based on mutual information

Shape complexity has recently received attention from different fields, such as computer vision and psychology. In this paper, integral geometry and information theory tools are applied to quantify the shape complexity from two different perspectives: from the inside of the object, we evaluate its degree of structure or correlation between its surfaces (inner complexity), and from the outside, we compute its degree of interaction with the circumscribing sphere (outer complexity). Our shape complexity measures are based on the following two facts: uniformly distributed global lines crossing an object define a continuous information channel and the continuous mutual information of this channel is independent of the object discretisation and invariant to translations, rotations, and changes of scale. The measures introduced in this paper can be potentially used as shape descriptors for object recognition, image retrieval, object localisation, tumour analysis, and protein docking, among others

Point sampling with uniformly distributed lines

In this paper we address the problem of extracting representative point samples from polygonal models. The goal of such a sampling algorithm is to find points that are evenly distributed. We propose star-discrepancy as a measure for sampling quality and propose new sampling methods based on global line distributions. We investigate several line generation algorithms including an efficient hardware-based sampling method. Our method contributes to the area of point-based graphics by extracting points that are more evenly distributed than by sampling with current algorithms

El Turisme, present i futur

L’aparició del turisme ha estat una de les claus per a entendre la transformació que ha patit la plana del Baix Ter, tant pel que fa al paisatge humà com al paisatge físic. Les raons de la massificació del turisme a la Costa Brava serien la bellesa de l’entorn, la bona climatologia i l’oferta de serveis a un preu assequible

L'embassament de Boadella: antecedents, execució i repercussions locals d'una infraestructura hidràulica

L' objectiu fonamental d’aquest article és aprofundir en les implicacions socials i territorials que té la realització d’una gran infraestructura hidràulica com és un embassament. Aprofitant que l’Alt Empordà compta amb una de les dues úniques grans obres d’aquesta tipologia existents a totes les comarques gironines, s’ha pres com a cas pràctic d’estudi l’embassament de Boadella. A l’article s’analitzen quins van ser els antecedents que conduïren a la seva construcció i quins van ser els efectes directes que va tenir sobre el lloc de realització. Més al marge es deixaran les seves conseqüències a la plana i al litoral altempordanesos. Es farà una radiografia sobre com era l’espai que quedà ocupat per les aigües i el seu poblament i com va repercutir el projecte a sobre d’ells. Tot plegat, sense perdre de vista els contextos històric i geogràfic que envoltaren la seva execució

Interpretación sedimentológica y paleogeográfica del nivel de areniscas eocénicas de Sarrià de Ter (Prov. de Gerona)

There is in this work a description of sedimentological characters of the medium Eocene sandstone level from Sarriá de Ter (Gerona province Spain) and an interpretation of their genesis and situation in the regional paleogeography. The conclusion is that these sandstones form a deltaic channel(delta front). To wards the E and NE the become fluvial deposits, to wards the W, Plana de Vic, they become clay and silstones considered as a prodelta
