The main objectives of the study are to develop a generalized thermo-electromechanical model of a solid-state heat engine based on a Ni-Ti-Cu shape memory alloy for converting low-grade thermal energy (30-100 °C) into e...

Coastal zone is transitional area between land and sea. Under the impacts of climate change, coastal zone is threatened by stressors such as sea-level rise, intensified storm surges. It is a common trend in global coasta...

Abstract This study presents the optimization and performance analysis of a tandem solar cell structure with the solar cell capacitance simulator in one dimension (SCAPS-1D). The novel monolithic two-terminal (2 T) tand...

Abstract Biological production of adipic acid, a crucial building block in nylon and polymer manufacturing, from renewable feedstocks has attracted attention as a sustainable alternative to the traditional petrochemical ...

The analysis and modeling of educational data are of great significance to the evaluation of teaching quality and personalized learning guidance. However, the acquisition of academic data is often limited by the costs of...

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...

This study focuses on the detonation performance and equation of state (EOS) of a low-density composite explosive mixed in a certain proportion of PBX-9502 powder and 502 glue. The theoretical analysis method was used ba...

BackgroundThe surface subsidence induced by coal seam mining represents a continuous dynamic evolution process. Constructing a full-time perdition model for surface subsidence in goafs holds significant theoretical and p...

The aim of this work is to create the scientific foundations of microwave extractors implementing the effect of mechanodiffusion discovered by the authors, as well as visual, kinetic, and energy substantiation of the fun...

Investigations into the collection of seafloor massive sulfides have had a relatively late start, with few related achievements. Moreover, most existing studies have focused on the collection of spherical particles. Ther...

ObjectiveThe conventional inversion of surface direct-current (DC) resistivity data faces challenges such as limited exploration accuracy and depth. This study aims to enhance the accuracy and reliability of exploration ...

Abstract In structural engineering, the behavior and strength of reinforced concrete haunched beams (RCHBS) are crucial, especially when shear strength governs design. Despite the advantages of RCHBS, several building co...

In response to the inaccuracy model of low-voltage power grid, a solution method based on AMI(advanced metering infrastructure) data and metering point errors of electricity meters is proposed. This method analyzes the e...

In response to the threats posed by underwater explosions to the stability of island-reef engineering structures and coral reef ecosystems, this study investigates the dynamic response characteristics and carbon emission...

This study presents pioneering research addressing the challenge of surrounding rock control in gob-side entry retaining by roof cutting under the conditions of a gently inclined coal seam with an extra-thick main roof r...

This systematic review of 79 CubeSat antenna studies reveals a progressive “workflow attrition cascade” (68% $\rightarrow 70$ % $\rightarrow 87$ % $\rightarrow 92$ %) wherein electromagnetic design sophisti...

ObjectiveLimestone water hazards in coal seam floors represent one of the two primary categories of mine water hazards in China. Limestone aquifers are generally characterized by abundant static water reserves and consid...

To refine the theoretical framework of earth pressure calculation and enrich its practical applications, a theoretical analysis of unsaturated Rankine’s earth pressure was conducted. Based on the triple-shear unified s...

Three-phase pulse width modulation (PWM) rectifiers are crucial in industrial, civil, and transportation applications. Due to the diversity of grid loads, the three-phase input voltage may be unbalanced, which consequent...

Abstract Targeting the environment of gas-cooled reactors (800 °C, 1 Mpa), we propose an all-sapphire composite-cavity sensor system for pressure measurement with in-situ temperature compensation. The sensor based on ...

Radiography or X-ray imaging is a diagnostic imaging used in medicine to produce images of inner anatomical structures such as bones, teeth, lungs, and chest organs. Impulse noise is one of the major factors that degrade...

To address the sensitivity of traditional Two-Dimensional Principal Component Analysis (2DPCA) to outliers and the breakdown of variance-reconstruction equivalence under noise, we propose an Angle-Aware Weighted 2DPCA (A...

Wood is a natural material widely used in construction. Unlike artificial building materials, wood is characterized by natural defects (flaws) that can negatively affect its performance under load. This study proposes a ...

This paper proposes a novel wireless power transfer system that integrates full-duplex communication functionality with negligible crosstalk between coupling coils. The system employs an LCC circuit as the overall topolo...
