Therefore, real-time dynamic strain monitoring of bogies is essential for predicting and preventing high-speed train accidents. Compared to traditional Non-Destructive Testing and Evaluation (NDT&E) methods, Radio Frequency Identification (RFID) sensors are more suitable for Structural Health Monitoring (SHM) due to their wireless capabilities and cost-effectiveness. Here we propose a wireless real-time monitoring system that utilizes integrated RFID tags with microcontrollers and sensor modules for real-time dynamic strain monitoring of Einel-rad-Einelfahrwerk (EEF) bogies. The microcontroller converts analog signals into digital, enhancing environmental interference resistance. The RFID tags wirelessly transmit digital signals to readers and host computers. To verify accuracy and real-time dynamic strain detection capabilities of designed system, experiments were conducted in laboratory settings and on-site with high-speed train bogies. Experimental results validate the system's 200 Hz dynamic strain detection capability with a 70 cm operational range. Laboratory calibrations within 600-1400 με exhibited absolute errors <19.39 με (2.07%). On-site tests on bogies revealed absolute errors of 5.08 με (7.50%) for axle strain and 7.59 με (7.66%) for wheel hub lateral strain under operational conditions.","PeriodicalId":72644,"journal":{"name":"Communications engineering","volume":"4 1","pages":"87"},"PeriodicalIF":0.0,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12078583/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144082355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The optical fibers with an enhanced detection algorithm greatly boost optical detection sensitivity. Furthermore, the droplet charging to enhance the tip charging phenomenon is complemented and validated. The detection and sorting accuracy of enriching large-size H22 cells reached 99.8% and 99.3%, respectively, with the target cell concentration increased by nearly 86-fold.

A database of the lifecycle carbon footprint is set up from raw material to recycling.

Miniature fixed points offer a solution for International System of Units traceability of space radiation values.

We demonstrated a space temperature traceability technology, which realizes continuous temperature self-calibration across all-location region is achieved through near-site transfer mechanism of phase transition characteristics. A transfer link between fixed points-blackbody-remote sensor has been established. We further provided two traceability schemes and deployed eight miniature fixed points covering 234 K to 345 K. Experiments showed repeatability and long-term stability of 6.0 mK and 3.2 mK. Additionally, we exhibited the latest spaceborne blackbody, achieving the first on-orbit replication of 7.4 mK.

Here, we demonstrate a monolithically integrated O-band Ge/SiGe QCSE modulator operating at 100 Gb s-1, seamlessly integrated with silicon nitride (SiN) waveguides on both silicon and silicon-on-insulator substrates. Our modulator achieves <1 dB coupling loss, <63 fJ bit-1 energy consumption, and >5 dB static extinction ratio, while maintaining performance across a 20-80 °C temperature range. Leveraging CMOS-compatible fabrication processes, we incorporate multiple quantum-well stacks grown at wafer scale on silicon, enabling large-scale production. The modulator's substrate-agnostic integration with back-end of line grown SiN layers, presents a scalable approach for cost-effective co-integration of electronic and photonic components.

Unlike other model-free approaches, the reservoir controllers are sample-efficient, meaning a weighted average of the reservoir output can be trained with a limited amount of pre-recorded data. However, developing and testing the reservoir controller relies on repetitive experiments that require researchers' proficiency in both robot and reservoir design. In this paper, we propose a design method for reliable reservoir controllers by synchronizing the timescales of the reservoir dynamics with those observed in the robot. The results demonstrate that our timescale alignment test filters out 99% of ineffective reservoirs. We further applied the selected reservoirs to computational tasks including short-term memory and parity checks, along with control tasks involving robot trajectory tracking. Our findings reveal that a higher computational capability reduces the control failure rate, though it concurrently increases the trajectory-tracking error.","PeriodicalId":72644,"journal":{"name":"Communications engineering","volume":"4 1","pages":"81"},"PeriodicalIF":0.0,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12043989/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144042320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we experimentally validate a photonic-integrated neuromorphic accelerator that uses a hardware-friendly optical spectrum slicing technique through a reconfigurable silicon photonic mesh. The proposed scheme acts as an analogue convolutional engine, enabling information preprocessing in the optical domain, dimensionality reduction, and extraction of spatio-temporal features. Numerical results demonstrate that with only 7 photonic nodes, critical modules of a digital convolutional neural network can be replaced. As a result, a 98.6% accuracy on the MNIST dataset was numerically achieved, with an estimation of power consumption reduction up to 30% compared to digital convolutional neural networks. Experimental results using a reconfigurable silicon integrated chip confirm these findings, achieving 97.7% accuracy with only three optical nodes.","PeriodicalId":72644,"journal":{"name":"Communications engineering","volume":"4 1","pages":"80"},"PeriodicalIF":0.0,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12038015/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144059687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
