SUMY, Ukraine — Ukrainian soldiers had grown used to the deadly drones stalking their vehicles and chasing them through doors and windows — until they met ones they couldn’t stop. New drones were ...

We develop a comprehensive theoretical model for fluorescence-based fiber optic sensors that accounts for multimodal excitation, incoherent emission from a homogeneously distributed ensemble of ...

A bird’s nest incorporating fiber optic cable is a striking sign of how much debris from fiber-guided FPVs now litters the landscape of Ukraine. Other images show fields glittering with fibers like ...

Khyzak REBOFF is a new Ukrainian FPV kamikaze drone with fiber optic cable for communication instead of radio. This makes it immune to jamming, the most effective protection against small drones.

Existing studies 1,2 have demonstrated that mechanical faults are typically preceded by characteristic precursors in acoustic vibration signals. This study focuses on fault monitoring of conveyor ...

Big quote: Light, not silicon, could someday define how artificial intelligence stores and recalls its knowledge. That's the idea that recently surfaced when John Carmack – the engineer known for his ...
