Algorithm based on simulated annealing for land use allocation
(Elsevier, 2007-09-02)This article describes the use of simulated annealing for allocation of land units to a set of possible uses on, the basis of their suitability for those uses, and the compactness of the total areas allotted to the same ... -
O abandono de terras: concepto teórico e consecuencias
(Universidade de Santiago de Compostela, 2008)O abandono de terras e a conseguinte diminución da superficie utilizada pola agricultura constitúe un problema importante nun gran número de rexións da Unión Europea entre as que se atopa Galicia. A posta en marcha do ... -
A Density Management Diagram Including Stand Stability and Crown Fire Risk for Pseudotsuga Menziesii (Mirb.) Franco in Spain
(International Mountain Society, 2009)A static stand density management diagram was constructed for Douglas fir (Pseudotsuga menziesii [Mirb.] Franco) plantations in Spain on the basis of 3 equations that were fitted simultaneously by the full information ... -
Site index model for natural stands of rebollo oak (Quercus pyrenaica Willd.) In Galicia, NW Iberian Peninsula
(Universidade Federal de Santa Maria, 2010)Data from stem analysis of 56 dominant trees of Quercus pyrenaica Willd., in natural stands in Galicia (NW Iberian Peninsula), were used to evaluate four dynamic site equations derived with the Generalized Algebraic Difference ... -
Análisis de los factores que condicionan la evolución de los usos del suelo en los pequeños asentamientos urbanos de la costa norte de Galicia
(Asociación Española de Geografía, 2010)La estructura urbana condiciona en gran medida su evolución futura. En el presente trabajo se analiza la evolución de los usos del suelo en un área rururbana de la costa norte de Galicia, identificando los procesos de ... -
Implications in the design of a method for visual grading and mechanical testing of hardwood structural timber for assignation within the European strength classes
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2011)The European strength class system (EN 338:2009) is based on a testing standard (EN 408:2004) that is not easy to use with hardwoods, although some of this type of timber, such as European oak (Quercus robur L.), is ... -
Manual GPS guidance system for agricultural vehicles
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2011)In this paper, the performance of a manual GPS guidance system to assist farming operations is evaluated. The distribution of granular fertilizer was simulated in order to discretize areas with excessive application of ... -
Root temperature and energy consumption at different cable depths in electrically heated substrates
(Universidade de São Paulo, 2011)A finite element method-based model of a substrate heated by an electric heating cable buried in a thermal isolated container was experimentally validated with root mean square error values of root zone temperature ranging ... -
