Variable-density groundwater flow models are often used to understand the complex nature of coastal groundwater systems. Hydrodynamic dispersion is a difficult process to represent with a model because of spatially varying hydraulic conductivity and temporally varying hydrologic boundary conditions. Temporal variations in water levels, for example, that occur in the field are often averaged int...

In speech research using real-time magnetic resonance imaging (RT-MRI), frame reconstruction is typically performed with a constant temporal resolution. However, a flexible selection of temporal resolution is desirable because of natural variations in speaking rate and variations in the speed of different articulators. In this work, a novel spiral golden-ratio temporal view order was applied to...

assessing the quality of groundwater is important to ensure the sustainablesafe use of these resources. however, describing the overall water quality condition isdifficult due to the spatial variability of multiple contaminants and the wide range ofindicators (chemical, physical and biological) that could be measured. therefore, in thiscase study, some water quality parameters including na, mg,...

"> The present study described the diversity of wheat and barley varieties andlandraces available in farmer’s fields in Syria using different indicators. Analysisof spatial and temporal diversity and coefficient of parentage along withmeasurements of agronomic and morphological traits were employed to explain thediversity of wheat and barley varieties or landraces grown by farmers in Syria.Farm...

[1] Scales of temporal and spatial variability of clear‐sky land surface temperature (LST) in middle latitudes are empirically evaluated using data from satellite and land surface observations. We consider separately the time‐dependent expected value, its spatial variations, weather‐related temporal and spatial anomalies, and errors of LST observation. Seasonal and diurnal cycles in the time‐de...

Separation of red blood cells and plasma in microcirculatory vessels produces a cell-free layer at the wall. This layer may be an important determinant of blood viscosity and wall shear stress in arterioles, where most of the hydraulic pressure loss in the circulatory system occurs and flow regulatory mechanisms are prominent. With the use of a newly developed method, the width of the cell-free...

â â  a great portion of precipitation in the south western iran falls in the snow formation. surface runoff produced from melting snow has an important role in the recharging ground water, surface and subsurface flows. rapid snowmelt can even cause flooding . since the snowmelt cannot be easily detected from optical satellite images, snow cover area (sca) is derived as an important hydrological...
