China's high-speed railway (HSR) construction industry has been experiencing a golden period of opportunities in the recent decades. Due to necessity protecting arable lands and advantage rapid construction, bridges (elevated structures) are predominantly used HSRs, which must meet critical small settlement requirement. This article first reviews main technical standards small- medium-span HSR bridges, where their comparison with Japanese standard International Union Railway is highlighted....
Abstract Currently, high‐performance polymerized small‐molecule acceptors (PSMAs) based on ADA‐type SMAs are still rare and greatly demanded for polymer solar cells (PSCs). Herein, two novel regioregular PSMAs (PW‐Se PS‐Se) designed synthesized by using centrosymmetric (linear‐shaped) axisymmetric (banana‐shaped) as the main building blocks, respectively. It is demonstrated that photovoltaic performance of can be significantly improved optimizing configuration SMAs. Compared to SMA‐based...
Efficient force identification of bridge cables is important to the performance evaluation cable-supported bridges. For this purpose, sensors are conventionally installed on record vibration responses, which nevertheless time-consuming and labor-intensive. This study develops a fully automated noncontact cable method using microwave radar sensing, enabling forces group be identified simultaneously thus largely improving efficiency. The fast sieve with linear time complexity proposed find...
In this study we investigate the feasibility of using passive bistatic radar to exploit WiMAX communication signals as transmitters opportunity for marine surveillance. The range and Doppler characteristics such a system are first assessed through ambiguity function analysis on typical set data transmission waveforms. Theoretical simulations then used ability detecting vessels within three busy shipping areas in UK, presence noise interference signals. initial shows resolution 5.6 m is...

A novel asymmetric acceptor, M36-FCl, has been developed by chemically hybridizing two symmetric M-series acceptors: one with fluorinated terminal groups (M36F) and the other chlorinated (M36Cl). This...
This study proposes a framework to accurately simulate the fluctuating wind and aerodynamic forces relative moving trains. It provides novel method for calculating power spectra of trains time–frequency transform admittance function unsteady forces. The proposed demonstrates broader applicability than existing methods, particularly in complex environments characterized by inhomogeneity non-stationarity. Moreover, it presents consider phase simulating Considering characteristics...
We modified the work of Wang and Zou , where both costs benefits fear effects were considered, a constant time delay was used to represent biomass conversion from prey predator. In our work, we assumed that digestion is not constant, but rather follows specific distribution. The modeled using general kernel function, more functional response function also employed. Then, established an integral–differential model with distributed delays. show there exists delay-dependent threshold determines...
As the load and working environment temperature increasing, high efficiency oil lubrication was urgently needed for main bearing of aeroengine.

To investigate the vibration characteristics of long-span suspension bridges under impact high-speed trains, a method for conducting time–frequency domain analysis dynamic response coupled system is presented in this study. First, finite element model bridge established to conduct modal analysis, and simulation results are compared with measured data validate correctness model. Subsequently, multi-body dynamics train developed. Then, two approaches, dummy flexible-track method, employed...
Bridge bearings experience numerous small‐amplitude displacements under environmental loads. The continuous cyclic accumulations of these will result in severe wear on the poly‐tetra‐fluoro‐ethylene (PTFE) plates bridge bearings, which seriously endangers service life bearings. Traditional method directly uses linear rate cumulative a short period to evaluate wearing life, but only such as several days may not represent characteristics whole life. Hence, this research takes spherical steel...
