Abstract This study presents a numerical framework for analyzing dispersion and wave propagation in spatiotemporally modulated metamaterials. A one-dimensional periodic spring–mass system with space- and time-dependent...

In this paper, firstly, based on Halpern iterative algorithm, Mann iterative algorithm, shrinking projection algorithm and hybrid midpoint rules, we introduce two modified strong convergence algorithms for nonexpansive m...

Widespread attention has been drawn to the underwater biomimetic robotic fish due to its excellent agility and little environmental disturbance. A hybrid-driven bionic robotic fish outfitted with dual-propeller thrusters...

In modern construction, steel trusses remain one of the most common types of load-bearing structures used in the construction of industrial, civil, and public buildings. Their use is driven by high load-carrying capacity...

Dynamic fault trees (DFTs) are widely adopted in industry to assess the dependability of safety-critical equipment. Since many systems are too large to be studied numerically, DFTs dependability is often analysed using M...

Abstract In current research on deflector jet servo valves, the receiver pressure estimated using traditional two-dimensional simulation and theoretical calculation is always lower than the experimental data; therefore, ...

The results of a predictive analysis of the mock-up of a reactor containment building, based on computer numerical simulation, are presented in this paper and compared with the results obtained in the context of the VeRC...

This paper presents a combined numerical and empirical investigation of how propagation channel conditions shape Modulation Error Ratio (MER) in UHF DVB-T broadcasting. A MATLAB/Simulink DVB-T physical-layer model is ext...

Abstract This work conducts a comprehensive numerical study of a concentrated photovoltaic–thermal (CPVT) system equipped with a V-trough reflector, with the objective of enhancing output power under realistic operatin...

Porous metallic structures such as Kelvin cells have attracted increasing attention due to their high surface-to-volume ratio and design flexibility, making them promising candidates for lightweight and efficient heat ex...

To simulate the joint network around mining tunnels and to conduct the stability analysis of tunnels in jointed rock mass, a numerical model for jointed rock mass containing particle flow block model, original joint netw...

Abstract Electromagnetic problems with moving structures are considered. For objects moving at a uniform velocity, the most popular technique used in the literature consists of a change of the reference frame and the uti...

Abstract This study develops and analyzes a Caputo fractional-order SEIHRD model to investigate the transmission dynamics and control of Ebola virus disease. The model ensures positivity, boundedness, and invariance of f...

The Nipah virus (NiV) is a zoonotic pathogen known for causing severe illnesses in both animals and humans, including encephalitis and respiratory issues. In this study, we present a nonlinear system of ordinary differen...

The Bahía Blanca Estuary is a complex system of channels and tidal flats where the most important deep water harbour system of Argentina is located. The main goal of the present work was to obtain a hydrodynamic conce...

Abstract The Pehlivan chaotic system, introduced by Ibrahim Pehlivan and Yilmaz Uyaroglu, is a three-dimensional autonomous chaotic model with rich dynamical properties. This paper develops a numerical framework for the ...

The paper presents a methodology and an example of determining the floor response spectrum of nuclear power plant building structures under earthquake loads. When critical energy infrastructure facilities are consider...

In the first half of this paper, we present a fresh perspective toward the Wind Triangle Problem in aerial navigation by deriving necessary and sufficient conditions, which we call "go/no-go conditions", for the existenc...

Numerical analysis of basal upheaval stability of foundation pits is a very important method in researches on deep excavation engineering, which is in the initial development stage and is of important issues remained to ...

Abstract Objective To investigate the association between ultrasonically detected fetal urinary system abnormalities and chromosomal copy number variations (CNVs) in Heilongjiang Province, northeastern China. Methods Coh...

Abstract Objective To explore the utility of microarray technology in prenatal diagnosis of nasal bone agenesis or hypoplasia. Methods Between July 2018 to October 2023, several cases of abnormal nasal bone development w...

By introducing the artificial intelligence technology, on improved Nelder-Mead acceleration algorithm based on the neural network is proposed to obtain better optimization results. A back analysis method for construction...

Abstract In the present study, we examine how optical solitons behave in a synthetic nonlocal nonlinear medium. An analytical investigation is conducted into the nonlinear dynamical model that represents the propagation ...

Abstract Large-diameter monopiles are extensively used to support onshore bridges, port terminals, and offshore wind farms due to their high load-bearing capacity, low settlement and excellent seismic performance. Meanwh...
