[es] Este trabajo examina la magnitud y la frecuencia del transporte de sedimento (material disuelto, sedimento en suspensión y carga de fondo) en la cuenca de la riera de Arbúcies (Cordilleras Costeras Catalanas), a partir de los caudales diarios del periodo 1967-1992 y de las muestras de agua y sedimento obtenidas durante los años 1991 y 1992. Lo...

Dating recent peat deposits (i.e., past } 300 yrs of peat accumulation) has emerged as an important yet challenging task for estimating rates of organic matter accumulation and atmospheric pollutant deposition in peatlands. Due to their ombrotrophic nature and the tendency for Sphagnum-derived peat to have high cation exchange capacity, peatlands a...
As a part of the GLORIA-EUROPE project, the floristic diversity, frequency and species coverage in relation to the main ecological gradients (altitude,aspect) were studied in the alpine pasture (Primulo-Caricetum curvulae, Oreochloo-Juncetum trifidi) and subalpine dwarf shrub communities (Rhododendro myrtifolii - Vaccinetum ) of the four summits fr...
As the sensorial capacity of the robots increases, for example with the availability of MEMS sensors, it will be a requisite for good real-time performance to wisely select and manage them, in order to fulfill the strong time requirements of machines moving in human environments. This work represents a first approach towards solving this kind of pr...
In this work, we developed an adaptive fuzzy controller which : 1) does not require an accurate mathematical model of plant under control; 2) uses the error vector as controller's input, therefore it does not require all that components of state vector to be measurable; and 3) guarantees the global stability of the close-loop system. The simulation...
Experiments were carried out to prove the effectiveness of the proposed dynamic weighted voting technique. The experiments were carried on fourteen experimental fields with four different behaviour combinations. The results and comparison of the different experiments wee discussed. These results appear to show that the dynamic weighted voting techn...
