The synthetic aperture focusing technique (SAFT) is a well-established method for improving the resolution of an ultrasonic image. A major shortcoming is the inherent assumption that the pulse reflected from a flaw has a spectral content that is independent of the flaw's location relative to the transducer. In this project, we address the issue by using SAFT combined with Wiener filtering and a...
Synthetically focused imaging has been used for some time in the NDE community. The techniques have primarily been directed towards imaging using bulk waves. There has recently been use of SAFT (Synthetic Aperture Focusing Technique) using guided waves in plates. Here, we review three different synthetically focused imaging algorithms for a linear array aperture: CSM (Common Source Method), SAF...
We propose a GPU-accelerated implementation of frequency-domain synthetic aperture focusing technique (SAFT) employing truncated regularized inverse k-space interpolation. Our achieves sub-1s reconstruction time for data sizes up to 100 M voxels, providing more than tenfold decrease in as compared CPU-based SAFT. provide an empirical model that can be used predict the execution quasi-3D any siz...
In this work, the PC-SAFT equation of state (EoS) has been used to model the solubility of acid gases (CO2 and H2S) in two imidazolium-based ionic liquids (ILs) ([C8-mim][PF6] and [C8-mim][Tf2N]). Parameters of pure ILs were estimated using experimental densities. Two strategies were considered to model densities of pure ILs. In strategy 1, ILs were modeled as nonassociating compounds and in st...
To clarify the pathogenesis of chronic eosinophilic pneumonia (CEP), the apoptosis of eosinophils from bronchoalveolar lavage (BAL-Eos) was compared with that of eosinophils from peripheral blood (PB-Eos) in six cases of CEP. The survival rate of eosinophils and the percentage of apoptotic cells of both types of eosinophils were examined, and the effects of interleukin 5 (IL-5) were evaluated. ...
A statistical associating fluid theory for potentials of variable range to model dipolar fluids is presented. The new theory, termed the SAFT-VR+D equation (the statistical associating fluid theory for potentials of variable range plus dipole), explicitly accounts for dipolar interactions and their effect on the structure of the fluid. This is achieved through the use of the generalized mean sp...
در این پژوهش مایعات یونی با پایه ی ایمیدازولیوم انتخاب شده اند که دارای دو زنجیره ی آلکیلی هستند، یک زنجیره ی آلکیل ثابت ( متیل ) و زنجیره ی دیگر از بوتیل به هگزیل و اکتیل تغییر می کند. آنیون های این مایعات یونی نیزقابل تغییر است نظیر تترا فلوئورو بورات و هگزا فلوئورو فسفات و بیس( تری فلوئورو متیل سولفونیل ) ایمید. در این پژوهش با معادلات حالت pc-saftو heterosegmented-saft این مایعات یونی برر...
Galectin-3 (Gal-3), a β galactoside-binding lectin, is implicated in the pathogenesis of allergic airway inflammation and allergen-challenged mice deficient in Gal-3 (Gal-3(-/-)) exhibit decreased airway recruitment of eosinophils (Eos). Gal-3 is expressed and secreted by several cell types and can thus function extracellularly and intracellularly to regulate a variety of cellular responses. We...
Understanding of CO2 hydrate–liquid water two-phase equilibrium is very important for storage in deep sea and submarine sediments. This study proposed an accurate thermodynamic model to calculate solubility pure seawater at (HLWE). The van der Waals–Platteeuw coupling with angle-dependent ab initio intermolecular potentials was used the chemical potential hydrate phase. Two methods were describ...
