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...

The effect of freeze-thaw cycles on the frost resistance of energy tunnels in cold regions

Seasonal temperature fluctuations in cold regions induce freeze–thaw cycles that can significantly impact the structural safety and maintenance of tunnels. This study uses the Daban Mountain Tunnel as a case study to develop a full-scale nu...

EVALUATION OF ARTIFICIAL NEURAL NETWORK APPLICATIONS IN TRANSPORTATION ENGINEERING

The increased interest in artificial neural networks (ANNs) seen in government and private research as well as business and industry has included relatively little activity in transportation engineering. The position that ANNs, as a branch ...

Research on Visualization Technology of Production Process for Mechanical Manufacturing Workshop

The visualization of workshop information can affect production management and efficiency. Information can be presented both graphically and non-graphically (for example, in the form of data lists or tables). Graphical representations are i...

Analysis of methods for accounting cargo vehicles in traffic flow of a regulated crossroad

Introduction. The formation of a ‘cargo frame’ around large cities leads to a change in the composition of the traffic flow on bypass roads, and an increase in the total traffic flow of trucks of various categories. In addition, the active ...

Effects of Titanate Coupling Agent on Engineering Properties of Asphalt Binders and Mixtures Incorporating LLDPE-CaCO3 Pellet

This study was initiated to evaluate the performance of asphalt binders and mixtures incorporating linear low-density polyethylene- calcium carbonate (LLDPE-CaCO3) pellet, either with or without titanate coupling agent. The detailed manufac...

Designing Functional Carriage of High-Speed Medical Train – Systematic Analysis and Evaluation of Tasks, Functions and Flow Routes

This paper proposes a functional carriage design and an evaluation index system to improve the operational efficiency of high-speed medical trains. Hierarchical task analysis and human-machine-environment analysis were applied to model the ...

ANALYSIS OF TRAIN SHEET IN THE INFORMATION SYSTEM OF JSC «UKRZALIZNYTSIA»: PERSPECTIVE

Purpose. The system of train sheet analysis (TSA) in the information system of JSC «Ukrzaliznytsia» provides work with passenger and suburban trains and has considerable potential. Therefore it is necessary to establish the prospects of dev...

Fuzzy logic systems for transportation engineering: the state of the art

Transportation Engineering

The shipments were absolutely necessary at all times, but still have polluted and damaged the environment. The technique of transport or the engineering of transport is the application of the principles of technology and scientific findings...

Algae-Mamba: A Spatially Variable Mamba for Algae Extraction From Remote Sensing Images

To maintain marine ecosystem health, effective algae monitoring is essential. Traditional threshold-based methods and standard machine learning techniques often fall short in accurately and automatically distinguishing algae types. This stu...

SHORT NOTE - World’s deepest karst hydrologic system documented in Sierra de Juárez, Oaxaca, Mexico

Mexico is rapidly being recognized as possessing some of the most spectacular and deepest caves in the world. Six of the 46 cave systems in the world that have been explored to depths greater than 1,000 m are in Mexico (Minton, 1994). Two o...

Adsorption Preceding Wetting Front Controls Seismic Velocity

Abstract Rock elasticity varies with both humidity and water saturation, yet their combined effects remain poorly understood, although in nature vapor adsorption and liquid infiltration occur simultaneously. Here, we present experimental da...

Upper wind observing systems used for meteorological operations

Methods of upper wind measurements used in operational meteorology have been reviewed to provide guidance to those developing wind profiler radar systems. The main limitations of the various methods of tracking weather balloons are identifi...

Comparison between electrical resistivity tomography and tunnel seismic prediction 303 methods for detecting the water zone ahead of the tunnel face: A case study

In deep tunnels with hydro-geological conditions, it is paramount to investigate the geological structure of the region before excavating a tunnel; otherwise, unanticipated accidents may cause serious damage and delay the project. The purpo...

Integration of remote sensing and geophysics in geological mapping of southern block of Chitradurga Schist Belt areas in upstream Cauvery basin, Western Dharwar Craton, Karnataka

We present mapping and comparision of the geology of the southern block of the Chitradurga schist belt (CSB). We have used ASTER images and geophysical data to compare the geology. Consequently, present study confirms how remote sensing int...

New Occurrence of Seifertite and Stishovite in Chang’E‐5 Regolith

Abstract High‐pressure minerals in impact ejecta quantify shock conditions and provide clues for provenance analysis. The sampling site of Chang’E‐5 may contain distal ejecta, which is critical for constraining the impact events and interpr...

Integrating uncertainty propagation in GNSS radio occultation retrieval: from excess phase to atmospheric bending angle profiles

Global Navigation Satellite System (GNSS) radio occultation (RO) observations are highly accurate, long-term stable data sets and are globally available as a continuous record from 2001. Essential climate variables for the thermodynamic ...

Effects of Concrete Grades on Strength Characteristics of Metakaolin Modified Recycled Aggregate Concrete

In this study, locally produced Metakaolin (MK) was used as an admixture in recycled aggregate concrete of grades M 25 and M 30. The content of MK varied from 0-15% at 5% intervals. The physical and mechanical properties (bulk density, spec...
