Abstract In this study, we developed a micromechanical model for exploring the longitudinal tensile behavior of unidirectional discontinuous flax fiber reinforced epoxy composites, emphasizing the significant roles of the aspect ratio of fibers and fiber-matrix interfacial properties. Representative volume elements (RVEs) are built using a novel approach which accounts for the randomness of the fiber distribution, discontinuity of the fibers, and the modeling of the interfaces as cohesive zone elements.
Finite element simulations of the RVEs under longitudinal tension were performed with proper periodic boundary conditions (PBCs). We investigated how fiber aspect ratio, interfacial properties and matrix… More >

Abstract Peripheral nerve injury can result in significant motor or sensory impairment. Traditional treatments have certain drawbacks and often result in suboptimal clinical results. To overcome these limitations, tissue engineering and bioprinting technologies are promising approaches for manufacturing nerve guidance conduits (NGCs). NGCs are tubular biostructures that bridge the nerve injury site, provide an appropriate microenvironment, and promote peripheral nerve regeneration by guiding axonal growth. The architecture of NGCs needs to mimic the morphology of natural peripheral nerves by designing their topology to regulate nerve cell behaviours. Topographic guidance cues are an effective element in improving… More >

Abstract Under the partial shading conditions (PSC) of Photovoltaic (PV) modules in a PV hybrid system, the power output curve exhibits multiple peaks. This often causes traditional maximum power point tracking (MPPT) methods to fall into local optima and fail to find the global optimum. To address this issue, a composite MPPT algorithm is proposed. It combines the improved kepler optimization algorithm (IKOA) with the optimized variable-step perturb and observe (OIP&O). The update probabilities, planetary velocity and position step coefficients of IKOA are nonlinearly and adaptively optimized. This adaptation meets the varying needs of the initial… More >

Abstract The rapid adoption of Internet of Things (IoT) technologies has introduced significant security challenges across the physical, network, and application layers, particularly with the widespread use of the Message Queue Telemetry Transport (MQTT) protocol, which, while efficient in bandwidth consumption, lacks inherent security features, making it vulnerable to various cyber threats. This research addresses these challenges by presenting a secure, lightweight communication proxy that enhances the scalability and security of MQTT-based Internet of Things (IoT) networks. The proposed solution builds upon the Dang-Scheme, a mutual authentication protocol designed explicitly for resource-constrained environments and enhances it… More >

Abstract Federated Edge Learning (FEL), an emerging distributed Machine Learning (ML) paradigm, enables model training in a distributed environment while ensuring user privacy by using physical separation for each user’s data. However, with the development of complex application scenarios such as the Internet of Things (IoT) and Smart Earth, the conventional resource allocation schemes can no longer effectively support these growing computational and communication demands. Therefore, joint resource optimization may be the key solution to the scaling problem. This paper simultaneously addresses the multifaceted challenges of computation and communication, with the growing multiple resource demands. We… More >
