Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Network coding-based protection scheme for Elastic Optical Networks [PDF]

2014 10th International Conference on the Design of Reliable Communication Networks (DRCN), 2014
Optical technologies are the foundations supporting the current telecommunication network backbones due to the high speed transmissions achieved in fiber optical networks. Traditional optical networks consist of a fixed 50 GHz grid, resulting in a low optical spectrum (OS) utilization, specifically with transmission rates above 100 Gbps.

Demonstration of all-optical inverse multiplexing in elastic optical networks

, 2014
We propose all-optical inverse multiplexing in elastic optical networks using superchannel multicasting to achieve efficient spectrum utilization. We show the benefit by simulation and demonstrate the feasibility by experiment on OFDM superchannel. ? OSA

DigiChrom: A Domain Ontology for Semantic Representation of Trivalent Chromium Platings and Its Large Language Model‐Based Alignment With Multiple Mid‐Level Ontologies

Advanced Engineering Materials, EarlyView.
Digitalizing electroplating requires both domain knowledge and interoperability. This work introduces PlatOn, a domain ontology for trivalent chromium plating and coating characterization, and a hybrid pipeline that aligns it to a mid‐level reference ontology by combining eight similarity metrics with language model reasoning. Expert‐validated mappings

Spectral Reallocation In Lightpaths Encompassing The Most Fragmented Link Of Elastic Optical Networks

, 2017
Dynamic allocation and release of lightpaths cause spectral fragmentation and degrade the bandwidth occupation in elastic optical networks (EON). Spectral reallocation and defragmentation strategies are key issues to minimize this problem and should be ...

Architecture‐Driven Sensor Stability in Weft‐Knitted Engineering Textiles

Advanced Engineering Materials, EarlyView.
Textile‐integrated sensor architectures are systematically compared to evaluate their electromechanical behavior under combined mechanical and environmental loading. Pocket‐based integration exhibits stable and reproducible signals, whereas tunnel‐based routing shows higher sensitivity accompanied by increased variability.
