Using the Monte Carlo (MC) method, this paper derives arithmetic and geometric means and associated variances of the net capillary drive parameter, G, that appears in the Parlange infiltration model, as a function of soil texture and antecedent soil moisture content. Approximate expressions for the arithmetic and geometric statistics of G are also obtained, which compare favourably with MC gene...

We present in this paper a method of image segmentation (T-CAAR) based on a fuzzy logic tree. The construction of the classes corresponding to regions of interest has been made by an upset of membership function and a fusion operator into a tree structure. The comparison of this method with fuzzy c-mean, mean shift and watershed allows using an appropriate technique for biotechnological bioproc...

In this paper we present a template-based method of motion estimation which tracks two-handed-gestures. In our method the gesturing information of temporal motion and spatial luminance is fully utilized. The dominant motion of the detected region corresponding to the tracked object (some hand or the head) is computed. Using this result the object template is warped to yield a prediction templat...

T paper describes the use of multiple-objective decision analysis to qualitatively and quantitatively assess the quality of an endangered watershed and guide future efforts to improve the quality of the watershed. The Upham Brook Watershed is an urban watershed that lies at the interface of declining inner-city Richmond, Virginia, and growth-oriented Henrico County. A section of stream within t...

Population and economic growth, the consequent increase in food demands have put great pressures on environmental resources they are driving rapid LULC changes. This study is aimed to examine impacts of land use/land cover changes hydrology Upper Gilgel Abay watershed. Landsat images (Landsat 5 TM 1986, ETM+ 2003, 8 OLI-TIRS 2021) were categorized into classes following supervised image classif...

Abstract The effects of watershed subdivisions on hydrological simulations have not been evaluated in Arctic conditions yet. This study applied the Soil and Water Assessment Tool threshold drainage area (TDA) technique to evaluate impacts subdivision at a 5,913-km2 watershed, Målselv. was discretized according four TDA scheme scales including 200, 2,000, 5,000, 10,000 ha. different schemes wate...
