Hyperspectral (450-2500 nm) airborne HyMap imaging spectrometer data (spatial resolution 5 m) were processed for mapping of environmental effects on vegetation due to talc mining activities at Lahnaslampi, Sotkamo, Finland. As a part of the european MINEO project, the HyMap imagery was interpreted by applying vegetation indices, using standard classification and hyperspectral mapping approaches...

This paper details the application of a genetic programming framework for classification of decision tree of Soil data to classify soil texture. The database contains measurements of soil profile data. We have applied GATree for generating classification decision tree. GATree is a decision tree builder that is based on Genetic Algorithms (GAs). The idea behind it is rather simple but powerful. ...

In the boreal region, soil organic carbon (OC) dynamics are strongly governed by the interaction between wildfire and permafrost. Using a combination of field measurements, numerical modeling of soil thermal dynamics, and mass-balance modeling of OC dynamics, we tested the sensitivity of soil OC storage to a suite of individual climate factors (air temperature, soil moisture, and snow depth) an...

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract Predicting discharge in ungauged catchments requires knowledge on the distribution and spatial heterogeneity of hydrological soil properties. Because hydrological soil information is not available on a European scale, we reclassified the S...

[1] In the past, texture-based classification of soils has been used for grouping soils in variably saturated water flow and solute transport studies. Classification of soils becomes especially important for large-scale studies where the spatial and temporal variability in the hydraulic properties of soils exceeds the field sampling capabilities. Although soiltexture-based classification has be...

in recent years, in order to enhance the health of agroecosystems, concerns on ecological inputs especially to produce medicinal plants, has been increased. in order to evaluate the effects of winter cover crops on pgprs activities and soil nitrogen content in simultaneous application of organic manures and biological fertilizer in a low input production system of cucurbita pepo under minimum t...

We classify all the structure groups which arise as subgroups of the isotropy group, (Spin(7) ⋉ R8) × R, of a single null Killing spinor in eleven dimensions. We construct the spaces of spinors fixed by these groups. We determine the conditions under which structure subgroups of the maximal null strucuture group (Spin(7) ⋉ R8) × R may also be embedded in SU(5), and hence the conditions under wh...

it is proposed to use a single base platform in the persian gulf considering its low depth and more appropriate environmental conditions in comparison to north sea and mexico gulf where this kind of platform is very popular. the pile of platform is responsible for transmission of environmental loads resulted from waves, currents, wind and dead loads to foundation of platform. using sacs 5.3 sof...

BACKGROUND A major challenges in the analysis of large and complex biomedical data is to develop an approach for 1) identifying distinct subgroups in the sampled populations, 2) characterizing their relationships among subgroups, and 3) developing a prediction model to classify subgroup memberships of new samples by finding a set of predictors. Each subgroup can represent different pathogen ser...
