Pipeline joint coating is key to maintaining the integrity and service life of oil and gas pipelines. This study presents a novel full-process automatic joint-coating system, comprising a modular design of a universal chassis and four operational mod...

The antiformal negative flower structure of the Shahejie Formation in the Southwest Sag of Dongpu Depression is the main target of rolling exploration evaluation, but there is limited understanding of its hydrocarbon accumulation events. In this stud...

Carbon Capture and Storage (CCS) is a critical technology for promoting carbon reduction and achieving the carbon neutrality goal. As a vital component of CCS projects, the injection process makes it especially important to clarify wellsite layout me...

Aluminium is widely used in electrical and structural applications; however, its lower electrical conductivity compared to copper limits broader adoption in high-performance systems. Deep cryogenic treatment (DCT) and DCT followed by annealing (DCT+A...

Extreme working conditions place high demands on material properties. For example, tools for friction stir welding of titanium alloys must be highly wear-resistant, have high strength at high temperatures, and also have high adhesion properties. Thes...

Safety and security are major priorities in modern society. Especially for vulnerable groups of individuals, such as the elderly and patients with disabilities, providing a safe environment and adequate alerting for debilitating events and situations...

We propose a novel optical method for performing integer division N÷D, based on the superposition of two transmissive masks: a dividend mask (G1) encoding N lines, and a completer mask (G2) providing blocks of D sites. The combined pattern is...

Besides the closed-form expansion coefficients of a weak-form numerical differentiator (WFND), we introduce a cubic boundary shape function with the aid of two parameters for reducing the boundary errors of fourth-order numerical derivatives to zero....

Under the dual carbon goals, microgrids face significant challenges in managing multi-energy flow coupling and maintaining operational robustness with high renewable energy penetration. This paper proposes a novel dynamic pressure-aware spatiotempora...

As a support material for mine roadways, shotcrete (SC) exhibits performance limitations in extreme deep-mining environments characterized by high stress and water seepage. Polyoxymethylene (POM) fiber, with its properties of high strength, high modu...
