Design and analysis of smooth geometry‐conforming lattices via Generalized Bézier patches
Abstract We propose a novel methodology to model globally G 1 geometry‐conforming metamaterials using Generalized Bézier‐based (GB) patches. Since every canonical tile is inscribed in a unit cube, we exploit its natural decomposition in octants and design multi‐sided patches for...

A Review of Input Current Ripple Reduction Techniques in Non-Isolated DC–DC Boost Converters
Input current ripple reduction in DC-DC boost converters is a persistent challenge because input current ripples are driving up filter requirements, electromagnetic interference (EMI), and stress on sources and loads. This ultimately limits power density and efficiency in many ap...

Grid-forming inverters (GFMIs) are essential for future low-inertia power systems because they establish voltage and frequency rather than simply following the grid. However, compared with synchronous machines, they have limited overload and fault current capability, so providing...

Passive Back-Support Exoskeletons Reduce Cumulative Spinal Loading During Aeronautical Tasks
Effects of passive back-support exoskeletons (BSEs) on internal spinal loading during aeronautical tasks remain unclear. We quantified changes in L5/S1 compression force while 19 male participants performed representative aeronautical polishing and handling tasks (sustained flexe...
- Materials & EnergyOpen access
Structural applications require materials that provide an optimal balance of strength, durability, and sustainability. This study develops functionally graded sisal/glass fiber-reinforced polymer composites and evaluates their tensile, compressive, and flexural properties, as wel...
