AMI-Assisted High-Capacity DWDM Optical Transmission with MIMO-OFDM for Future Networks

Line coding plays a critical role in determining the performance and reliability of digital communication systems. This paper proposes a novel high-speed optical transmission method that employs Alternate Mark Inversion (AMI) line coding in a DWDM system integrated with an OFDM m...

Context-aware image captioning using cosine transformer attention and optimal vision transformer with improved walrus optimization algorithm

Abstract Automatic image captioning aims to acquire the learning of the correlation between the visual and the linguistic cognitive domain through the generation of descriptive captions with respect to input images. But it is affected by the semantic distance between image featur...

Hierarchical federated edge learning with criticality-aware aggregation for privacy-preserving fetal health classification

The automated classification of fetal health from cardiotocographic (CTG) recordings is a crucial machine learning application in obstetric diagnostics. Although centralized predictive models have advanced significantly, their large-scale clinical deployment remains structurally...

A review on interfacial and microstructural control of tribological performance in Material Extrusion (MEX)-printed nanocomposites

Abstract Material Extrusion (MEX) is one of the most popular methods used for 3-D printed polymer-based functional parts; however, the possibility of limited wear resistance coupled with frictional behaviour is an issue with many of these parts. The effect of type of nano-filler,...
