Unmanned aerial rotorcraft vehicles have many military, commercial and civil applications. There is a necessity to advance the performance on several ranges of rotorcraft for using these vehicles successfully in the expa...

Anaerobic co-digestion of livestock waste presents a viable approach for addressing environmental challenges and reducing greenhouse gas emissions in semi-urban and rural contexts. This study focuses on the development o...

Today’s farming is up against the tough task of boosting crop yields while also taking care of the environment. The way pesticides and herbicides are usually applied can be a real hassle. It's often not very efficient,...

The military aggression of the Russian Federation against Ukraine, through the use of the full range of enemy aerial attack means not only against military targets but also against critical infrastructure objects (herein...

Structural health monitoring (SHM) has become a central tool for managing civil infrastructure. In modern SHM, the physical structure and the SHM system together form a coupled cyber-physical system. Due to the networked...

Abstract Large language models are beginning to appear in civil engineering practice, yet their advice often reflects generalized narratives rather than local evidence. This perspective introduces a governance audit fram...

It can be said that today's civil aviation basics began to be laid in the 1950s. This date is also important as the period in which the rules are being written and at the same time, some system solutions are produced by ...

The application of Internet of Things (IoT) technology is a significant step toward improving the sustainability and responsiveness of the built environment. The current work introduces the Adaptive and Sustainable IoT I...

This paper proposes an innovative automated multiphysics Microelectromechanical systems (MEMS) co-optimization platform integrating the embedded reduced-order modeling offered by Coventor MEMS+ with MATLAB’s numerical ...

Recent advancements in helmet design demonstrate that mimicking natural models can enhance both aerodynamics and safety protection. Thus, this paper comprehensively reviews the bio-inspired helmet designs reported in the...

Abstract This study aims to develop a performance grade (PG) zoning map for asphalt pavements along the Kabul–Salang Highway in Afghanistan, considering local climatic conditions and traffic factors, to support optimiz...

This work presents and validates a direct analytical methodology for the parametric hydrodynamic design of Pelton rotors. The proposed approach combines a one-dimensional theoretical framework for defining global geometr...

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 ...

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 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...

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...

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...

With the rapid expansion of the digital music industry, streaming platforms are required to efficiently and accurately classify massive music collections to support personalized recommendation, content organization, and ...

Traditional static security assessments difficult to capture the dynamic strategic interactions and behavioral decision-making inherent in extreme nuclear security risks. To address this, we propose a tripartite evolutio...

In the seismic design of reinforced concrete moment-resisting frame (RC MRF) structures equipped with steel damper columns (SDCs), design criteria should consider both peak responses (e.g., story drift) and cumulative re...

Abstract The development of sustainable infrastructure in Nigeria requires the effective use of native timber species in designed constructions. This study assesses the structural integrity of glue-laminated timber (Glul...

Culverts play a critical role in stormwater conveyance, roadway safety, and flood mitigation, particularly within low-lying urban communities vulnerable to extreme rainfall events. In Louisiana, increased rainfall intens...

Electricity bill sharing among occupants of multi apartment buildings in Nigeria is often based on equal cost allocation, a practice that leads to billing disputes, unpaid charges, and unjust cost sharing among users wit...

Abstract Concrete production’s environmental impact has driven the use of supplementary cementitious materials like sawdust ash (SDA) and admixtures such as Conplast to enhance sustainability and performance. This stud...
