In this study, a novel least square support vector machine (LSSVM) model integrated with gradient-based optimizer (GBO) algorithm is introduced for the assessment of water quality (WQ) parameters. For purpose, three stations, including Ahvaz, Armand, and Gotvand in Karun river basin, have been selected to electrical conductivity (EC) total dissolved solids (TDS). First, prove superiority LSSVM-...

Research from this laboratory has recently demonstrated that the omasal epithelium of sheep is capable of absorbing dipeptides. In order to express proteins potentially responsible for the mediated absorption of small peptides, size-fractionated poly(A)+RNA (RNA) isolated from omasal epithelial tissue of sheep (average BW 67.5 kg) were injected into defolliculated Xenopus laevis oocytes. The ab...

This paper deals with the numerical computation of electromagnetic (EM) energy absorption by biological tissues. It is indeed one of the important challenges for the computational EM community to estimate rate of EM energy absorption by human tissues to asses the potential health hazard quantitatively. This is usually quantified in terms of SAR, which is the normalized rate of energy absorbed b...

In many parts of the world, groundwater is considered to be a key source fresh water for both domestic and non-domestic sectors. Where extraction implemented, systems monitor quality must ensure safe sustainable supply. Over years, Iraq has suffered from surface supply problems, necessitating in regions. This study investigates region central around Babylon city, covering an area 5119 km2. The ...

This paper presents the numerical evaluation of the microwave absorption at 2.4 GHz (ISM band) in a homogeneous rectangular head model. Specific absorption rate(SAR) reduction in the head model is achieved by attaching nickel-zinc spinel ferrite sheet resonating at 2.4 GHz to a mobile phone. RF shields made of ferrite sheets are used to suppress surface currents on the mobile phone. Simulations...

This paper presents faster Specific Absorption Rate (SAR) measurement techniques based on a previously proposed estimation method. This estimation method theoretically estimates the SAR from a 2-D scanned electric field (E-field) by basically applying the equivalence theorem and the image theory. The method reduces the SAR measurement time without sacrificing accuracy. We present the applicabil...

This paper presents a new Specific Absorption Rate (SAR) measurement technique that employs the ElectroOptic (EO) probe. Conventionally, the electric field (E-field) probe comprising diode-loaded dipole sensors is employed for SAR measurements. We developed a prototype of a three-axis EO probe for SAR measurement. This three-axis EO probe is capable of measuring both the amplitude and phase of ...

Synthetic aperture radar (SAR) images due to the usage of coherent imaging systems are affected by speckle. So lots of despeckling filters have been introduced up to now to suppress the speckle. Hence, objective and subjective evaluation of the denoised SAR images becomes a necessity. Thereby lots of objective evaluating estimators are introduced to evaluate the performance of despeckling filte...
