The editorial function of the territorial intelligence systems
2006
This communication makes an updating of our thinking about the editorial function of the systems of territorial intelligence. Computer science and information systems aim at increasing the communication between the human beings. A territorial intelligence system is an instrument at the service of the actors who ambition to control the development the equitable and sustainable development of their territory. Since the irruption of data processing, we led research activities to design friendly software, then to model the structure of a territorial information system that is at the service of a network of territorial actors, and more recently to integrate the data analysis functions. They led …
Modelling of the Universe : Simulation of the GPS (The Global Positioning System)
2007
Masteroppgave i informasjons- og kommunikasjonsteknologi 2007 – Høgskolen i Agder, Grimstad ParAbel is a project at Agder University College aims at mathematics and physics on Internet. One of the sub projects named SimReal [2] (Simulation in ‘Realfag’), which currently aims at simulating behaviours and properties of universe for both mathematics and physics studying. This project focuses on simulation of the GPS which is one sub task in SimReal. In this paper, on the one hand, we will set up a GPS simulation model and use it to be a teaching material for learning mathematics and physics. On the other hand, by testing the simulation model among the college students, we will discuss about th…
An environmental forensic procedure to analyse anthropogenic pressures of urban origin on surface water of protected coastal agro-environmental wetla…
2013
Detection and spatial distribution of 14 drugs of abuse and 17 pharmaceuticals in surface waters was investigated to determine transport hydrological connectivity between urban, agriculture and natural environments. Solid-phase extraction and liquid chromatography tandem mass spectrometry was applied to all samples. To determine spatial incidence of contaminants, analytical results of target compounds were georeferenced and integrated into a geographical information systems structure together with layers of municipal population, location of sewage water treatment plants and irrigation channels and sectors. The methodology was applied to L'Albufera Natural Park in Valencia (Spain). A total o…
Cattle as actors in a pastoral landscape. Gis analysis of an agropastoralist group
2018
In the study of pastoral landscapes, ethnoarchaeology can incorporate first-hand information on material features and herding prac- tices and identify the active role of domestic animals in such practices. The Mursi are a present day transhumant agro-pastoralist group, which are specialized in the livestock herding of cattle (Bos indicus). This study examines evidence from this animal behaviour and its needs, which allows us to enrich a particular construction of a herding landscape in contemporary SW Ethiopia. Remote sens- ing techniques are employed to obtain landscape snapshots of the Mursi main pasture area, which are contrasted with fieldwork data. Moreover, recent improvement in digit…
La valeur économique des paysages des villes périurbanisées
2007
La recherche présentée ici propose une méthode de description et d’évaluation des caractéristiques d’un paysage qui combine la géographie quantitative et l’économétrie des modèles hédoniques. Un modèle géographique produit des indices caractérisant les paysages à partir d’une reconstitution de la vue depuis le sol, en tenant compte des effets du relief et des masques que les objets hauts opposent à la vue. Il décrit la quantité de paysage vu par un observateur au niveau du sol en la répartissant entre 13 types d’occupations du sol. Les variables produites par le modèle géographique sont utilisées dans des régressions hédoniques qui permettent d’évaluer l’impact des attributs paysagers ain…
Understanding Urban Fabric with the OH_FET model based on Social Use, Space and Time
2008
The proposed principle for understanding the urban fabric is based on considering the town as a set of complex objects, taking a systemic approach. The town system used to study the urban fabric over large time spans is composed of three sub-systems relating to historical objects from the level of the excavation to that of the former urban space: function (social use), space (location, surface area and morphology) and time (dating, duration and chronology). The historical object is the analytical unit of the space studied. It is the Cartesian product of the three sets, Social use, Space and Time, from which it stems. On the basis of this process, the Historical Object (OH) is broken down in…
Paperless survey? New methodological approaches to archaeological fieldwork, the case of Navarrés (València)
2014
El trabajo que presentamos se ha desarrollado en el marco del proyecto NSF “The Emergence of Coupled Natural and Human Landscapes in the Western Mediterranean” en el área comprendida por la actual comarca de La Canal de Navarres, situada al suroeste de la provincia de Valencia. Este espacio se convierte en una de las áreas elegidas para un programa de recogida de datos centrado en la prospección sistemática “off site “. En las jornadas “Dando sentido a la prospección arqueológica” nos centraremos en los aspectos metodológicos que hemos desarrollado para llevar a cabo el trabajo de campo. Esta ha sido la primera vez que hemos realizado una prospección arqueológica, en una zona completamente …
Monitoring and predicting sediment yield in a small Sicilian basin
2001
Identifying areas of a basin that are most sensitive to erosion have stimulated the study of within–basin variability of the sediment–delivery processes and the use of spatially distributed models. To verify the reliability of a sediment–delivery distributed model applicable at the morphological unit scale (i.e., the area of clearly defined aspect, length, and steepness), experiments were carried out at mean annual and event scales in a small Sicilian basin. A Geographical Information System is briefly presented into which the measurements carried out at the basin outlet (runoff, sediment yield, etc.) and other point and areal information (soil erodibility, digital terrain model, etc.) were…
La Meseta de Requena-Utiel entre los siglos II-I a.C.: La Romanización del territorio ibérico de Kelin
2013
En la presente Tesis Doctoral se aborda el tema general de la romanización de los pueblos ibéricos en la fachada mediterránea peninsular a partir del caso concreto del territorio de una ciudad ibérica, Kelin – Los Villares (Caudete de las Fuentes, València). Dicha ciudad, ocupada entre los siglos VII-I a.C., sabemos que al menos desde el s. V a.C. organizó un territorio a su alrededor, con unos límites muy similares a los de la actual comarca de Requena-Utiel. Ha sido excavada desde los años 90 desde el Servicio de Investigación Prehistórica de la Diputación de Valencia y la Universitat de València, siendo la directora de la presente tesis la directora de la última fase de excavación, Consu…
Mapping floristic diversity: a case study in Sicily
2021
This paper presents an operational methodology to map and analyze the floristic richness of “target species” in Natura 2000 sites, making use of G.I.S. tools and procedures. A Floristic diversity map (scale 1:50,000), covering an area of 612 km2, was produced by a team of experts as part of the management plans of “Madonie Mountains” Sites of Community Importance (SCIs), located in Sicily (Italy). The primary grid map represents the richness of “target species”, which include species of Community interests, taxa on the National Red List, endemic and threatened, species protected under International Conventions, taxa of phytogeographic importance. Secondary data frames include a three-dimens…
