Summary: The demand for network capacity has increased due to new digital applications and services that rely heavily on optical communication networks. To avoid the challenge of deploying fiber in certain scenarios, a hybrid all-optical fiber/FSO link is proposed. Machine learning techniques, specifically Gaussian process regression, are used to predict channel impairments in the hybrid all-optical fiber/FSO channels. The results show high accuracy in predicting most impairments, except for light turbulence parameters under strong ASE noise. The proposed approach provides a self-aware and self-adaptive communication system and has the potential to optimize network resources in the future.

Summary: This paper explores the potential of hybrid materials combining steel or cast iron with fibre or particle composites for lightweight machine tool structural design with high damping ratio. Fiber composites and particle composites were successfully used to reduce component mass and improve damping ratio on single structural parts, while the improvement in damping ratio of hybrid components in assembly configuration is less significant. The importance of damping caused in the connecting interfaces was also highlighted in the study.

Summary: The use of larger CBN grains in grinding can improve material removal rates for hardened steel components and achieve higher depths of cut. Grinding with coarse grains results in lower process forces, higher residual stress, and rougher surfaces, with minimal wear observed. In some cases, using larger grains can enhance tool performance and allow for higher feed rates.
