FUSED-Net: Detecting traffic signs with limited data

Automatic Traffic Sign Recognition is paramount in modern transportation systems. However, curating large-scale datasets for diverse traffic sign detection remains impractical. In this context, we present FUSED-Net, a novel approach that enhances Few-Shot Object Detection (FSOD)...

Maximising Regenerative Energy Return from Dynamo-Motor Traction Drives in Solar PV-Powered Electric Vehicles for Long-Haul Operation with Strong Stability

Abstract This thesis develops a design method for maximising the energy returned to the traction store of a solar photovoltaic (PV) powered electric vehicle by a dynamo-motor traction drive over a long-haul mission, while maintaining strong small-signal and large-signal stability...

Blue Technology in Switchgear for Sustainable Power Transmission Systems: Dielectric, Switching, Life-Cycle and Techno-Economic Modelling of SF₆-Free Clean-Air and Vacuum Gas-Insulated Substations

Abstract Sulphur hexafluoride (SF₆) has been the reference insulating and arc-quenching medium of high-voltage switchgear for six decades, but with a global warming potential of about 24 300 and an atmospheric residence time of the order of 3 200 years it is now the single larges...

Optimization of double-diffusive mixed convection for a hybrid nanofluid system: A numerical and statistical coupled approach

There has been a lot of research on nanofluid convection, but not much on the impacts of double-diffusive mixed convection, hybrid nanofluids, and complex geometries like L -shaped cavities using combined statistical and numerical approaches. To fill that important gap, the aim i...

Scaffolding self-regulated science learning with multiple external representations in online environments

Abstract Multiple external representations (MERs) are central to learning abstract scientific concepts, yet most evidence on their effective use comes from teacher-guided settings. As online and blended learning environments expand, how students navigate and make sense of MERs wi...

Dietary patterns among women with polycystic ovary syndrome in Bangladesh: a cross-sectional comparison with women without PCOS

Polycystic ovary syndrome (PCOS) is a common endocrine disorder associated with reproductive and metabolic complications, for which dietary modification is an important component of management. Although previous studies have examined dietary patterns among women with PCOS, eviden...

Potential of Seaweed to Improve the Quality and Shelf Life of Fish and Fishery Products

ABSTRACT The rapid growth of the global population has increased the demand for safe, healthy, and sustainable food, and fish supplies about 20% of the world's protein demand. Fishery products are rich in nutrient compositions such as moisture, protein, lipids, minerals, etc. Moi...
