3D ultimate limit state analysis using discontinuity layout optimization [PDF]

, 2012
The recently developed discontinuity layout optimization (DLO) procedure uses limit analysis theory to directly obtain upper bounds on plane strain collapse loads of bodies and has successfully been applied to geotechnical problems.

Photonic Doping of Epsilon‐Near‐Zero Bragg Microcavities

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
Photonic doping of an epsilon‐near‐zero (ENZ) Bragg microcavity at optical frequencies induces strong magnetic responses from dielectric inclusions, enabling intense field localization, Purcell enhancement, and tunable hybrid Bragg–Mie modes. The platform supports perfect magnetic conductor and epsilon‐and‐mu‐near‐zero regimes, offering opportunities ...

Parameter‐Preserving Real‐time BIM Rendering via Direct GPU Ray Tracing

Computer Animation and Virtual Worlds, Volume 37, Issue 4, July/August 2026.
Parametric BIM geometry is preserved from Revit extraction to GPU ray tracing without mesh tessellation. A two‐tier cache reuses repeated geometry during export, and an instanced OptiX representation reduces memory at render time. The method lowers export time and GPU memory while preserving exact curved surfaces.
