Estudia filtros de microcinta con distribuciones de resonadores de anillos y resonadores de anillos complementarios divididos.

By using the Fourier-Bessel series expansion of wave function, obtained is the analytical solution to the dynamic responses of canyon with multiple arc-shaped alluvial layers under the incidence of plane SV waves. Compar...

The property of the soil in free field is an important influencing factor for the free field seismic response. In the existing studies the soil at local site is supposed to be the single-phase medium or saturated porous ...

A hybrid technique, FEM-IBIEM is developed for studying the scattering of seismic waves by a 3-D complex local site. The indirect boundary integral equation method (IBIEM) adopts the dynamic Green's functions of concentr...

In this work, carbon nanotube (CNT) based interconnections and switches will be reviewed, discussing the possibility to use nanotubes as potential building blocks for signal routing in microwave networks. In particular, ...

Nonlinear Schrödinger equations with power-law nonlinearities have attracted considerable attention recently. Two previous proposals for these types of equations, corresponding respectively to the Gross– Pitaievsky eq...

In this study, an all-optical multiplexer (Mux) based on elliptical insulator-metal-insulator (IMI) plasmonic waveguides is designed. The area of the proposed structure is very small (400 nm × 400 nm) which oper...

Indium tin oxide (ITO) has become an important material in photonics due to its transparency, high electrical conductivity, and, more recently, its epsilon-near-zero (ENZ) properties for nonlinear optics. In this work, w...

During tunnel construction using the drilling and blasting method, layered jointed rock masses often pose engineering challenges such as over- and under-excavation of the crown and working face. The authors addressed the...

The earthquake liquefaction is one of the direct causes for unstable ground and damage of upper structure. Therefore, the liquefaction assessment is an important part of anti-seismic investigation in engineering. By taki...

This study investigates the tensile mechanical properties of gray sandstone under dynamic impact. Drawing on the one-dimensional stress wave theory, we conducted a one-dimensional spallation experiment using a 50 mm diam...

The coefficient of lateral earth pressure at rest K0 of Shanghai soft clay is measured by the GDS stress path triaxial device. The shear wave velocity and the corresponding small strain shear stiffness at K0 state are al...

The mathematical methods of FFT and wavelet transform are used to deal with the acoustic emission (AE) frequency information of rock fracture firstly. Combined with the spectral distribution of AE signal, the main respon...

This study presents the dynamical analysis and soliton solutions of the Chaffee–Infante equation, an important nonlinear evolution model. The Chaffee Infante equation, widely employed as a reaction–diffusion model, i...

Abstract Stroke remains a primary cause of disability globally. An in‐depth comprehension of gait impairments following a stroke is vital for crafting effective therapeutic interventions, and vertical ground reaction f...

For a better understanding of the kinematics and mechanics of the Oriente transform fault, a left‑lateral boundary along Cuba's southern margin in the Caribbean, we use the seismic records to determine new deviatoric m...

Abstract Nitrogen-doped carbon dots (CDs) were prepared from essential fluorescent amino acids, such as lysine (Lys), phenylalanine (Phe), tyrosine (Tyr), and tryptophan (Trp) by two routes, microwave and teflon-lined au...

The low-frequency vibration stimulation technology can improve the seepage of fluid in low-permeability reservoir, which is rather deeper than that of the regular geotechnical formation. Few researches on the mechanisms ...

There is a series of symmetric deep-seated cracks (DSC) in the abutment slope of Yebatan Hydropower Station. The special geological phenomenon is analyzed to provide a scientific basis for a comprehensive analysis on roc...

The constraint conditions at pile head are assumed based on the case of Zhejiang Hotel Expansion Project, and then the deflection functions under different constraint conditions of pile tip and top are introduced. The to...

Based on theoretical analysis, the spectral element method is used to study the effect of bedrock terrain on ground motion. The achievements are as follows: (1) The intensity of bedrock ground motion is related to bedroc...

In this study, we evaluated a nanoscale random rubbed structure (nRRS) used as a scattering layer in organic light-emitting diodes (OLEDs) through an innovative manufacturing method. The rubbing technique, which is conve...
