ABSTRACT: Although the piezocone penetration test (PCPT) has several advantages over traditional methods of sampling and laboratory analysis in determining representative properties of a soil deposit, the existing methods used to infer soil properties from PCPT data are not always reliable due to the complexity of cone penetration. In this study, it is proposed that the process of “data fusion”...

To get land cover information of study city area, and according to the spectral feather of the wanted classes including water, vegetation, impervious surface, and soil at LANDSAT-TM remote sensing image, we used a method that using three indexes including normalized difference vegetation index, modify normalized difference water index, and ratio impervious surface index to extract the thematic ...

The goal of the study was to apply and modify the semiemperical water-cloud model to simulate bacscattering coefficients of C-VV and L-HH as a function of LAI, vegetation water content and soil moisture. Bacscattering coefficients were compared to these obtained from ERS-2.SAR and JERS.SAR measurements taken simultaneously for the agriculture area in Poland. During time of satellite acquisition...

NASA’s Soil Moisture Active Passive (SMAP) satellite mission combines a passive L-band radiometer and an active Synthetic Aperture Radar (SAR) instrument in order to monitor the near-surface soil moisture and freeze-thaw states globally, with a revisit frequency of 23 days. SMAP provides three soil moisture products: a high-resolution from the radar, a low-resolution from the radiometer, and an...

Land degradation is becoming one of the severest environmental issues in the world, especially in developing nations. Land degradation, usually accompanied by soil erosion, always results in a decrease or complete loss of land productivity, and produces on-site and off-site pollution to soil and water. The methods for land reclamation are various, including physical, chemical and biological. Th...

The interdependence of species richness and plant biomass has widely been accepted as a general biodiversity rule. However, there is no information about how relationships are established during colonization and how total biomass is distributed among plants. The main objective of this study was to determine the role of several factors which we have hypothetized as affecting biomass distribution...

childhood autism is a neurodevelopmental disorder characterized by impairments in social interactions, verbal and non-verbal communication and by a pattern of stereotypical behaviors and interests. the aim of this study was to estimate the dysmorphic facial features of children with autism and children with asperger syndrome.the examination was conducted on 60 children (30 with childhood autism...

spike sorting is a class of techniques used in the analysis of electrophysiological data. studying the dynamics of neural activity via electrical recording relies on the ability to detect and sort neural spikes recorded from a number of neurons by the same electrode. this article reviews methods for detecting and classifying action potentials, a problem commonly referred to as spike sorting.

The classification of soils originated from three main sources: from early empirical soil surveys, from folk soil classifications and from scientific theory of pedology. The first soil classifications reflected their origin in different extent, and still remain certain features of their initial sources. The actual situation in soil classification is discouraging, mainly due to the diversity of ...
