We investigate theoretically and demonstrate experimentally, the effect of material geometric periodicity in face sheets on overall dynamics sandwich beams. By treating two core as separate entities using classic plate theory (CPT), conjunction with Bloch theorem, solving governing equations transfer matrix method (TMM) generalized differential quadrature (GDQM), we obtain a low-frequency \text...

This paper investigates a 3D reconstruction based on the ultrasonic scanned data for tissue mimicking material (TMM) sample. A two-step varied window filter is developed to smooth ultrasound backscatter signals at first. Next, the anisotropic diffusion filter with a triangular window is presented to reduce the noise of the 2D images by aligning one-dimensional signals. Finally, the 3D structure...

According to cohen venavi, a classic Hebrew essay by Ekhad Ha-Am, there are two ways of serving God: Priest and Prophet. The priest is a very skilled technician who knows by heart the 613 mitzvahs, and who can slaughter a lamb with due regard to the many rigorous and subtle laws. On the other hand, a prophet is often very clumsy in the day-to-day ritual, and is unable to sacrifice an animal pro...

Finding new plasmonic materials with prominent optical properties and unique physical chemical characteristics, which are merits of traditional gold silver, is great interest to many applications. This work uses a series powerful numerical methods, such as density functional theory (DFT) electromagnetic modeling approaches, predict the response mechanically well-known material, zirconium nitrid...

We present a transfer matrix method which is particularly useful for solving some classes of sandpile models. The method is then used to solve the de-terministic nonabelian sandpile models for N=2 and N=3. The possibility of generalization to arbitrary N is discussed briefly.

In this paper, a highly sensitive graphene-based multiple-layer (BK7/Au/PtSe2/Graphene) coated surface plasmon resonance (SPR) biosensor is proposed for the rapid detection of novel Coronavirus (COVID-19). The sensor was modeled on basis total internal reflection (TIR) technique real-time ligand-analyte immobilization in sensing region. refractive index (RI) region changed due to interaction di...

The Slope Deflection Method is one of the displacement-based methods developed for structural analysis. In this study, an approach proposed static analysis continuous beams. basis includes Ricatti Transform, which was used in literature to get Transfer Matrix by using Finite Element Method. Transform applied firstly, application shown theoretically, and then two numerical examples were solved s...
