Significantly Enhanced Interlaminar Shear, Fracture Toughness, and Bending Behavior of Glass Fiber/Epoxy Laminates Containing Aligned Graphene Nanoflakes

ABSTRACT Achieving controlled through‐thickness alignment of graphene flakes within electrically insulating glass‐fiber‐reinforced polymer composites remains a significant challenge due to the limited effectiveness of externally applied electric fields in such structural material...

Single‐Phase Single‐Stage Isolated DC–AC Inverter With Double‐Frequency Current Ripple Compensation Port

ABSTRACT The single‐phase single‐stage isolated photovoltaic (PV) microinverter typically requires bulky electrolytic capacitors to buffer double‐frequency ripple power, limiting lifespan and power density. This paper proposes a novel single‐stage isolated DC–AC topology with an...

Adaptive Dragonfly Algorithm for AI-enabled path planning of humanoid robots in obstacle-constrained environments

Abstract Reliable path planning is a significant requirement for humanoid robots to move around in an environment filled with obstacles. In this paper, a novel method for humanoid robot navigation is proposed based on the Adaptive Dragonfly Algorithm (aDA), which is an improvemen...

Application of Machine-Learning Models on Analysis and Prediction of the Fatigue Life of Pavement Quality Concrete Made with Recycled Concrete Aggregate

Abstract Fatigue-life estimation of pavement quality concrete (PQC) used in concrete pavement is important in light of estimation of the design life of a pavement subjected to repeated applications of wheel load. The present study investigates the flexural fatigue performance of...

Power‑efficient low‑noise high linear single-stage 140 dB DC gain OTA for biomedical signal acquisition

An efficient operational transconductance amplifier (OTA) with high gain, high bandwidth, low noise, high CMRR, and low power is crucial for optimal performance of analog-mixed-signal (AMS) systems. This article presents a low-power, single-stage high-gain adaptive recycling fold...

Parametric optimization for drilling of multi-fiber (glass and steel) reinforced epoxy composites

Glass fiber reinforced polymer (GFRP) composites are widely used in structural applications, where drilling is essential for mechanical assembly but often causes damage that reduces joint quality. This study investigates the drilling performance of a newly developed hybrid compos...

Pseudo-static bearing capacity of skirted footings on sandy slopes using artificial neural network and random forest regression models

This study investigates the pseudo-static bearing capacity of skirted strip footings on cohesionless slopes using finite-element limit analysis and data-driven prediction models. A total of 216 numerical simulations were performed by varying soil strength, slope angle, seismic co...

Joint Optimization of Packet Survivability and Aerodynamic Energy for Dynamic UAV Activation in VANETs via Deep Q-Networks

UAV-assisted VANETs are a key component of the 6G vision, yet their practical deployment is hindered by the fundamental conflict between network Quality of Service (QoS) and the high aerodynamic power required for rotary-wing flight. This paper proposes SAVIOR (Survivable Aerial-...

Intelligent navigation of humanoid robots using modified African vulture-inspired fuzzy control

Path planning and navigation control of humanoid robots in uneven and unstructured environments are challenging due to terrain uncertainty, stability requirements, and real-time decision-making constraints. This study presents an intelligent path-planning and navigation technique...

STARSFLUX: an all-sky catalogue of absolute spectro-photometric calibrators from 0.3 to 30 μ m

Abstract Obtaining accurate fluxes of faint sources from the ground in near- and mid-infrared wavelengths is challenging because of the rapidly changing atmospheric absorption. A common limitation is the lack of a nearby spectro-photometric calibrator. We present the STellar Abso...
