A technique of using satellite-derived data for constructing continuous snow characteristics fields for distributed snowmelt runoff simulation is presented. The satellite-derived data and the available ground-based meteorological measurements are incorporated in a physically based snowpack model. The snowpack model describes temporal changes of the snow depth, density and water equivalent (SWE)...

PURPOSE To evaluate and compare the performance of shear-wave elastography (SWE) for breast masses using the local shear wave speed (m/sec) vs. Young modulus (kPa). METHODS A total of 130 breast lesions in 123 women who underwent SWE before ultrasound- guided core needle biopsy or surgical excision were included. With the region-of-interest placed over the stiffest areas of the lesion on SWE,...

INTRODUCTION This project concerns the identification of the smallest worthwhile effect (SWE) of exercise-based programmes to prevent falls in older people. The SWE is the smallest effect that justifies the costs, risks and inconveniences of an intervention and is used to inform the design and interpretation of systematic reviews and randomised clinical trials. METHODS AND ANALYSIS This study...

Twenty-four winter seasons (1978–2002) of mean February snow water equivalent (SWE) values were analyzed in an exploration of the spatial pattern of temporal variability in snow cover across the non-mountainous interior of Canada. The SWE data were derived from space-borne passive microwave brightness temperatures processed with a land coversensitive suite of algorithms. Spatial patterns in the...

Sensor engineering is continuously evolving as devices become cheaper, smaller, more intelligent, and more efficient. Today, oceanographic sensors aim at monitoring marine processes by means of physical, chemical, and biological variables, and use different data formats, units, parameters, resolutions, data quality standards, and protocols. Therefore, integration and interoperability at Europea...

Abstract. Manual measurement of snow water equivalent (SWE) is still important today for several applications such as hydrological model validation. This can be performed with different types tube sampler or by a pit. Although these methods have been decades, there an apparent lack information required to consensus regarding the best reference “true” SWE. We define and estimate uncertainty erro...

Aim: To determine the efficacy of kidney shear wave elastography (SWE) in patients diagnosed with ureteral stones.Method: Both kidneys 30 were evaluated prospectively SWE. The stone size and degree hydronephrosis determined by sonographic examination. contralateral was accepted as control parameter. Stone size, grade speed changes noted their relations examined for statistical significance.Resu...

BACKGROUND Primary open-angle glaucoma is a multifactorial serious disease characterized by progressive retinal ganglion cell death and loss of visual field. OBJECTIVES The purposes of this study were to investigate shear wave elastography (SWE) use in the evaluation of the optic nerve (ON) and peripapillary structures, and to compare the findings between glaucomatous and control eyes. PATI...
