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...

soil erosion causes sediments to be detached from their source materials and transported as suspended particles. the present study was conducted to evaluate the effects of sand exploitation on the distribution of suspended sediments in the educational and research forest watershed of tarbiat modares university, which comprises approximately 50,000 ha. fifty-one water samples were collected befo...

Texture analysis holds significant promise for improving the science return of remote planetary exploration. Communications with exploration spacecraft suffer significant latency and bandwidth constraints; onboard image understanding can summarize large datasets and select representative images for transmission. We present image texture descriptors that satisfy the strict computational requirem...

This paper proposes a framework for colour texture segmentation. The framework uses the colour and the texture distributions for discriminating the colour textured regions. The proposed colour texture segmentation method was tested in three different applications. The applications includes Irish Script on Screen (ISOS) images, skin cancer images and Sediment Profile Imagery (SPI). Image texture...

the understanding soil erosion processes and the development of accurate erosion prediction models require understanding of detachment, deposition and sediment transport in rills. to evaluate the effect of soil type and flow stream power on the relative importance of flow driven processes of sediment transport, and on the boundary between the processes regarding to particle size, experiments we...

Abstract A study on the suspended sediment transportation downstream from the Danjiangkou Reservoir in China has shown that the dynamics of suspended sediment grain size are complicated. During the period when the reservoir was used for flood retention, the suspended sediment median size decreased gradually; after entering the period when the reservoir was used for water storage, the median siz...

A total of 110 participants were interviewed to investigate the effect of hand measurements and gender on mobile phone messaging satisfaction. Physical measurements of hand-size and thumbs were recorded. This study focused on mobile phone keypad design factors; namely, key size, shape, texture, space between keys, layout and keypad simplicity. Females were found to be more satisfied with the ke...

this article present the result from a study of two sediment cores collected from theenvironmentally distinct zones of ces. accumulation status of five toxic metals: cadmium (cd), chromium(cr), cobalt (co), copper (cu) and lead (pb) were analyzed. besides texture and chns were determined tounderstand the composition of the sediment. enrichment factor (ef) and anthropogenic factor (af) wereused ...
