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...

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...

Constructing backfill walls adjacent to the yield coal pillar can effectively enhance its stability. The backfill and coal pillar form a synergistic bearing structure that jointly maintains the stability of the overlying...

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...

The characteristic oral environment – with its dynamic clearance, moisture, microbial load, and inflammatory potential – makes oral diseases highly prevalent and therapeutically challenging. Metal-organic frameworks ...

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...

Artificial intelligence (AI), machine learning (ML), and advanced computing techniques are now central to the digital transformation journey, reshaping industries, academia, and society. This special issue of the Journal...

In marine science and engineering, growing volumes of imaging data are used in exploration and monitoring. The process of manual annotation of this data (i.e. marking and describing objects of interest with labels), to e...

Abstract Simulating the response of granular materials under realistic loading scenarios is essential for ensuring the reliability of geotechnical infrastructure. This task is particularly challenging because natural soi...

Disease Diagnosis in crops is a very expensive and lengthy process, as it often involves the need for few experts to make observations, leading to delayed diagnosis, viral spread of diseases, and thus, massive economic l...

Reservoirs are critical infrastructure for global water, food, and energy security, yet their storage dynamics remain poorly characterized across most of the world. Accurate and timely knowledge of reservoir storage is e...

Synthetic biology is emerging as a frontier interdisciplinary discipline that is increasingly regarded as a key driver of sustainable innovation in advanced materials. By leveraging the design-build-test-learn (DBTL) cyc...

Pixel-level segmentation is critical for remote sensing applications, yet traditional supervised methods suffer from high annotation costs. While foundational vision models like CLIP and the Segment Anything Model (SAM) ...

This work presents a new Ultra Wide Band (UWB) beamforming fifth-order derivative Gaussian pulse transmitter with dual small Vivaldi antennas for remote acquisition of vital signals in impulse radar applications. The sys...

Abstract Radio-Frequency Identification (RFID) is one of the leading enabling technologies of the Internet of Things (IoT) at low cost and high granularity scenarios. The cost of implementing IoT applications concerns th...

Abstract This work presents the development of a reconfigurable frequency selective surface (RFSS) for application in the 2400-2483.5 MHz band, standard IEEE 802.11b/g/n (Wi-Fi). The proposed RFSS is based on the four-ar...
