Introduction Metallic vascular stents are widely used during revascularization procedures to improve the success rate of the intervention. However, metallic stents are also known to produce susceptibility and radiofrequency (RF) artifacts that can hinder the depiction of the stent lumen during subsequent magnetic resonance angiography (MRA) investigations [1]. Proposed solutions to the RF shiel...

Abstract. This paper presents a step-by-step procedure for the numerical integration of fractional differential equation governing response single-degree-of-freedom (SDOF) system with derivative damping. The is developed by extending improved pseudo-force method proposed second author classical equations. To this aim, Grünwald–Letnikov approximation adopted. exploited to compute statistics SDOF...

Determination of the internal stability of reinforced soil walls under earthquake conditions is an important part of seismic design. The horizontal method of slices is used for determining internal stability or for tieback analysis of the reinforced soil wall. A pseudo-dynamic method is adopted in the present analysis, which considers the effect of phase difference in both the shear and primary...

In this research, the modal parameters of a beam in free-free condition are extracted by performing different experiments in laboratory. For this purpose, two different techniques are employed. The first methodology is considered as a time domain method in Operational Modal Analysis. While the other one is frequency domain impact hammer test which is categorized as an Experimental Modal Analysi...

The buffeting analysis of an uncertain long-span bridge deck was carried out in this paper. Due to the effect strong spatial correlation wind excitation, it should be assumed as partially coherent multiple excitations. following includes a theoretical formula for with parameters, which achieved mainly by combination stochastic pseudo excitation method (SPEM) and response surface (RSM). SPEM-RSM...

axial distributions of plasma and floating potentials, electron number density and the electron energy distribution function (eedf) have been measured in the double layer (dl) region of an he discharge constriction. excitation processes in the constriction region are studied. using a linearization method for the nonstationary balance equations and choosing appropriate discharge conditions, the ...

Abstract Carbon–heteroatom (C–X) cross-coupling is a common method for bond-forming reactions in chemistry but the more electronegative heteroatom X is, challenging bond formation becomes. Although reductive elimination from Cu(III) intermediates to form C–X bonds generally facile reaction, oxidative addition of Cu(I) into carbon–(pseudo)halide aryl (pseudo)halides energetically challenging. Th...

It has great significance to research the dynamical reliability probability of rolling mill rolls system for improving its stochastic dynamical reliability and products quality rolled. The fifth-octave vertical vibration stochastic dynamical model of rolls system was established, and the pseudo-excitation method was used to obtain the power spectral density and the variance variation characteri...

We present the numerical, theoretical, and experimental study of a terahertz metasurface supporting pseudo-anapole. Pseudo-anapole effect arises when electric toroidal dipole moments both tend to minimum, instead destructive interference between in conventional anapole mode. Such overlap allows resonance suppression type radiation. Thus it becomes possible multipoles other families higher order...

Second order advantage of excitation-emission fluorescence matrix was applied for the simultaneous determination of ibuprofen and caffeine. The proposed method is based on the measurement of the native fluorescence and recording emission spectra of ibuprofen and caffeine in different excitation wavelengths. The mixture of these compounds was resolved by multivariate curve resolution coupled wit...
