This study aims to continuously optimize the exhaust manifold to ensure long-term stability of reliable performance, and focused on exhaust manifold examining low and high cycle fatigue at high temperatures. The thermal ...

Abstract Background Various designs of dental implants made of zirconium dioxide (zirconia) as an alternative to titanium implants are available as one-piece implant (OPI) or as bone-level or tissue-level two-piece impla...

Abstract Background With the high prevalence of periodontitis, tooth rotation resulting from periodontal damage can be corrected through orthodontic treatment; however, the biomechanical complexity of tooth movement in c...

Abstract Alkaline water electrolysis represents a promising pathway for green hydrogen production, yet comprehensive multi-physics simulation remains computationally prohibitive for practical design optimization. This st...

Abstract This paper presents a four-wheel differential-drive (4WD) autonomous platform that consolidates grass cutting, collection, leaf crushing, and precision seeding through modular, quick-release toolheads. A vertica...

In the present study, the transmission error (TE) behaviour of an identical involute spur gear pair dynamically coupled with an attached subsystem is investigated through numerical modelling. The surrounding mechanical s...

We present a magnetically actuated vocal fold–phantom phonation system capable of reproducing longitudinal tension modulation to mimic cricothyroid (CT) and thyroarytenoid (TA) muscle activation. We first formulat...

In view of the structural bearing performance issues of buried water diversion tunnels, the paper conducted a series of numerical simulation study on the joint bearing mechanism of steel lining-concrete lining-surroundin...

Abstract The use of textile fibre-reinforced composite materials for many alternative applications has significantly increased in the twenty-first century due to their lightweight nature and high strength-to-weight ratio...

The purpose of the present paper is to propose a novel approach of impact test system based on electromagnetic loading (EML) technology, which could provide more efficient and flexible experiment method with large range ...

Abstract To study the differences in insulation effects of foam box with ice packaging in the aircraft cargo hold environment and the normal pressure environment, and to understand the changes in refrigeration performanc...

Abstract The uncontrolled floor heave in gob-side entry retaining is the serious problem of underground coal mining. This phenomenon has gravely restricted the application of pillarless mining that has been increasingly ...

Auxetic materials, defined by their negative Poisson’s ratio, exhibit enhanced toughness, energy absorption, and improved shape retention, making them attractive for aerospace, biomedical, and flexible electronics appl...

With the expanding use of woven composites in critical load-bearing applications under harsh environmental conditions, it is essential to evaluate how hygrothermal exposure affects their performance. This study aims to s...

Abstract Bearing layers are commonly produced using coarse aggregates, gravel, and filler, where excessive filler content can reduce drainage performance. This study investigates an alternative production method for conv...

Electroslag welding involves high heat input, which may cause material hardening in the weld and heat-affected zone. At the same time, the electroslag weld is in an inaccessible state, making the welding quality difficul...

Introduction. Self-excited induction generators (SEIGs) play a vital role in renewable energy systems, particularly in remote regions. However, their performance is highly sensitive to excitation capacitance, rotor speed...

Abstract Bone tissue engineering scaffolds must provide structural support while permitting fluid transport and maintaining safe hydrodynamic conditions for cell activity. Triply Periodic Minimal Surface (TPMS) architect...

This study investigates the effect of discharge voltage on fracture distribution and fragmentation extent in multi-hole pulsed discharge rock fragmentation. Comparative experiments were conducted on red sandstone specime...

The present work investigates the compressive mechanical response of three lattice structures manufactured via VAT photopolymerization. A bio-inspired architecture, derived from the observation of Euplectella aspergillum...

Concrete-filled steel tubular (CFST) truss arch bridges are widely used in long-span bridge construction due to their high strength, good stiffness, and excellent durability. However, arch rib joints, as critical load-be...

Highly divergent and asymmetric beam profiles are an inherent limitation of facet-emitting mid-infrared semiconductor lasers and complicate their use in free-space optical systems. In this work, we demonstrate beam colli...

Excessive armature mass fraction in asynchronous induction coil thrusters critically constrains payload capacity and propulsion efficiency. This study addresses this limitation through two lightweight strategies: axial h...

In this paper, a near-field integrated sensing and communication (ISAC) using a multi-waveguide pinching antenna system (PASS) is proposed, where discrete radiating particles are flexibly clamped along multiple dielectri...
