Laboratory-scale characterization of saturated soil samples through ultrasonic techniques

Exploring accuracy of statistical characterization of gravel beds using Kinect device in the laboratory scale

Mountainous river beds-generally consist of gravel particles that the precise description of such bed is not only important hydraulically, but also it has great environmental significance. The accurate estimation of bed roughness gives us valuable information to make reliable hydraulic models of flow in river with rigorous bed form. This study discuses about the accuracy of the Kinect device in...

Elastic characterization of porous bone by ultrasonic method through Lamb waves

The object of this research is to characterize the porous bones by an ultrasonic method using Lamb waves. In recent years, the characterization of such materials has attracted many authors and takes a perfect place in the field of medicine. It requires the development of more efficient technology for getting the necessary quality and security. This paper aims to exploits the dispersion curves o...

Characterization of piezoelectric materials using ultrasonic and resonant techniques

Resonance technique for determining the physical properties of piezoelectric material can be difficult to implement for some low symmetry systems. Inconstancy may be introduced because several samples are needed and the degree of poling depends on sample geometry. The ultrasonic method on the other hand, allows the determination of a complete set of elastic, piezoelectric, dielectric constants ...

Characterization of Cs in Riyadh Saudi Arabia Soil Samples

The current study was conducted primarily to investigate and estimate Cs activity concentrations and the external dose rate due to fallout radionuclide Cs. Soil samples were collected from different 25 locations at Riyadh Province and analyzed using low level γ-spectrometry equipped with HPGe-detector. Cs activity concentrations and calculated dose rate were found in the range of 0.8 3.1 Bq·kg ...
