Accurate attenuation coefficient measurements are able to display the nature of selectivity in an image. The methods used to measure the attenuation coefficient are Monte Carlo probability and linear regression models. T...

Abstract In eddy current testing, the law of attenuation of eddy current (EC) is of great concern. In conductive half space under the excitation of uniform magnetic field, the EC density decreases exponentially in the de...

Abstract Objectives To prospectively evaluate the correlation between the attenuation imaging (ATI) parameter and hepatic steatosis in overweight (OW)/obese (OB) children, and to establish normal ATI reference values fro...

Due to the special characteristics of light in water, the information of the red channel is seriously attenuated in collected image. This causes other colors to dominate the image. This paper proposes an underwater image...

Abstract Underwater imaging suffers from various challenges such as color distortion, low contrast, and reduced visibility caused by light attenuation. Addressing these issues is crucial for improving the performance of ...

ABSTRACT For different dyes like methyl green, methyl orange, methyl red, malachite green, crystal violate, safranin, and methylene blue. We calculated their optical constants like wavelengths of maximum absorption, mol...

In modern society the work and athletic performance of horses has led to a very important animal production sector in which Brazil possesses the third largest horse stock. Among all equine lesions described, metacarpopha...

When an orbital-angular-momentum (OAM) beam propagates through the dynamic air–water interface, the aerosol above the water and the water surface curvature could induce various degradations (e.g., wavefront distortion,...

From 2017 to 2019, an extensive sampling campaign was conducted in Belgian inland and coastal waters, aimed at providing paired data of optical and biogeochemical properties to support research into optical monitoring of...

Abstract Objective To evaluate the diagnostic value of Revolution APEX energy spectrum CT imaging and quantitative parameters in T staging of pancreatic cancer (PCa). Methods Energy spectrum CT of 105 patients diagnosed ...

The underwater light climate has important effects on primary producers. The aim of this research was to evaluate its variability in a turbid river-floodplain system. Photosynthetically active radiation (PAR) was measure...

We provide a simple method that enables readily acquired experimental data to be used to predict whether or not a candidate molecular material may exhibit strong coupling. Specifically, we explore the relationship betwee...

This research deals with the preparation number of composite materials by casting the base alloy (Al-Co-Ni) by adding chromium oxide (Cr2O3) as reinforcement material, by weight ratios of (5, 10, 15 wt%) for the base all...

Zirconium (Zr), a metal with an hcp structure, has been investigated for the transmission of acoustic wave in the 0 to 25 GPa operating pressure. For this, the Lennard-Jones interaction potential approach has been used ...

Con el propósito de evaluar la variación temporal del estado trófico y la condición húmica del lago del Parque Norte (LPN), Medellín (Antioquia, Colombia), se realizaron muestreos quincenales entre marzo y agosto d...

A theory is developed for the propagation of stress waves in a porous elastic solid containing compressible viscous fluid. The emphasis of the present treatment is on materials where fluid and solid are of comparable den...

In this paper, a semi-empirical method for the prediction of rain attenuation in slant paths and terrestrial links is proposed. The method uses the same simplified model of equivalent rain cell that is the basis for the ...

Tsunami-like waves pose a serious threat to coastal infrastructure, necessitating effective mitigation measures to reduce inundation and associated damage. This study uses a numerical wave tank (NWT) to investigate the h...

Using specially designed low-temperature resonant column apparatus, change rules of dynamic shear moduli and damping ratio with negative temperature and their computational methods for three soils are investigated. Conce...

137Cs can be an important environmental contaminant due to fallout from nuclear reactor accidents and atomic weapons testing. Its contribution to the air gamma dose rate at 1 m height above contaminated ground depends on...

Abstract The friction judder characteristics during clutch engagement have a significant influence on the NVH of a driveline. In this research, the judder characteristics of automobile clutch friction materials and exper...

The NASA-ISRO Synthetic Aperture Radar (NISAR) mission will advance global soil moisture monitoring through high-resolution L-band observations. However, accurate fine-scale retrieval remains challenging due to the 12-da...

Abstract Objective To investigate whether virtual unenhanced (VUE) images generated from spectral CT using the rapid kVp switching technique can serve as a substitute for true unenhanced (TUE) images in the assessment of...

Abstract This work proposes the application of a slot in the ground plane, Defected Ground Structure (DGS), of a microstrip patch antenna. The application of this technique aims to attenuate higher-order excited modes wi...
