In order to improve the analysis effect of the international competitiveness of China’s new energy vehicle industry, this paper combines the improved AHP and grey relational analysis method to analyze the international competitiveness of Ch...

Managing energy consumption: a case of natural gas as a taxation tool in Ukraine

Energy consumption is managed to some degree in different countries. If the government is interested in reducing the energy poverty and increasing the energy consumption, it provides enough energy access for all consumers. However, sometime...

Re-examine weekday effects and intraday returns: a probability distribution approach for Dow and Nasdaq ten-minute indices

Predictions of FluSurge 2.0 methodology on hospital utilization during the Covid-19 outbreaks in several countries

Application of the Flusurge 2.0 methodology to predict the needs of conventional hospital treatment, intensive care, and respiratory support resources as a consequence of coronavirus disease (COVID-19) in several countries. Different countr...

Effect of road surface deformations on lateral lane utilization and longitudinal driving behaviours

Various road surface deformations generally occur on urban and rural roads due to infrastructure, superstructure deficiencies and excessive heavy vehicle loads. In addition to driver-based errors, many accidents happen due to these mentione...

Evolution characteristics of seepage-stress fields and optimization of waterproof-drainage system during operation period of urban tunnels with small interval

The long-term structural safety issues of water-rich tunnels under complex hydrogeological conditions during operation period and their mutual interaction mechanism with groundwater environment are receiving increasing attention. To study t...

The research of the temperature effect of steel-concrete composite bridges is of great significance to ensure the safety and durability. The latest research progress in the field of composite bridge temperature field is introduced, includin...

Modeling Of Polymer Melt Flow In The Annular Channel Of A Disk Extruder

Purpose. Polymer products are used in industry due to their performance properties. The homogeneity of the melt is essential for the quality of the final product. Uniform distribution of components and properties ensures homogeneity of the ...

Characterizing particle crushing behavior of dry granular soils by acoustic emission

This study investigates particle crushing mechanisms in granular soils during shearing through staged triaxial compression experiments performed at prescribed axial strains and varying confining stresses, integrating a high-performance acou...

Numerical investigation of corroded middle‐high strength pipeline subjected to combined internal pressure and axial compressive loading

Abstract Buried oil and gas pipelines may face the threat of geological disasters such as landslides, faults, and floods. However, long‐term buried oil and gas pipelines often have corrosion defects, which bring greater challenges to the sa...

Transportation engineering

Based on the existing VMS guidance effect maximization model, Niu’s work puts forth a fuzzyconstraint based VMS programming model. The model makes improvements on the original attenuation factor, increases the constraints of benefitcost, an...

Estimation for Two-Dimensional Nonsymmetric Coherently Distributed Source in L-Shaped Arrays

We explore the estimation of a two-dimensional (2D) nonsymmetric coherently distributed (CD) source using L-shaped arrays. Compared with a symmetric source, the modeling and estimation of a nonsymmetric source are more practical. A nonsymme...

Predicting Method for Lining External Water Pressure Reduction Coefficient Based on Equivalent Stable Drainage Volume Principle

［Objective］ By establishing a numerical seepage analysis model that aligns with real drainage systems and introducing the concept of a ′virtual permeability coefficient′ for secondary lining, the objective is to delve into the correlation b...

Hydrogen-powered drives of the rail vehicles (part 1)

The paper presents the reasons for launching the efforts aimed at implementing the lowemission rail vehicles. A short history of development of the hydrogen-powered drive solutions is described. It has been pointed out that implementation o...

Accidental explosions on the railway: simulation-based prediction of damage to nearby buildings

A procedure for estimating potential damage to buildings induced by accidental explosions on the railway is developed. By the damage failures of nearby structures due to actions generated by the accidental explosions are meant. This damage ...
