1. ID20-opportunities for inelastic X-ray scattering at extreme conditions 

   Sahle, Christoph J.; Petitgirard, Sylvain; Spiekermann, Georg; et al. (2024)

   High Pressure Research

   Owing to the availability of bright X-rays sources such as the ESRF-EBS, inelastic X-ray scattering of samples contained in complex sample environments, including high pressure devices, has become feasible. Compared to well-established characterization techniques such as X-ray diffraction or X-ray absorption fine structure spectroscopy, inelastic X-ray scattering of samples under extreme conditions is a relatively novel probe. However, ...

2. EFFECT OF HYDROGEN ENRICHMENT ON TRANSFER MATRICES OF FULLY AND TECHNICALLY PREMIXED SWIRLED FLAMES 

   Blonde, Audrey; Schuermans, Bruno; Pandey, Khushboo; et al. (2023)

   PROCEEDINGS OF ASME TURBO EXPO 2023: TURBOMACHINERY TECHNICAL CONFERENCE AND EXPOSITION, GT2023, VOL 3A

   Knowledge of flame responses to acoustic perturbations is of utmost importance to predict thermoacoustic instabilities in gas turbine combustors. However, measuring transfer functions linking acoustic quantities upstream and downstream of flames is very challenging in practical systems and these measurements can significantly deviate from state-of-the-art models. Moreover, there is a lack of studies investigating the effect of hydrogen ...

3. Polymers from Plant Oils Linked by Siloxane Bonds for Programmed Depolymerization 

   Cheng, Chen; Shi, Jake X.; Kang, Eun-Hye; et al. (2024)

   Journal of the American Chemical Society

   The increased production of plastics is leading to the accumulation of plastic waste and depletion of limited fossil fuel resources. In this context, we report a strategy to create polymers that can undergo controlled depolymerization by linking renewable feedstocks with siloxane bonds. alpha,omega-Diesters and alpha,omega-diols containing siloxane bonds were synthesized from an alkenoic ester derived from castor oil and then polymerized ...

4. Seismic hazard zonation map and definition of seismic actions for Greece in the context of the ongoing revision of EC8 

   Pitilakis, Kyriazis; Riga, Evi; Apostolaki, Stefania; et al. (2024)

   Bulletin of Earthquake Engineering

   The Greek National Annex for current Eurocode 8 has adopted the seismic hazard zonation map published in 2003 as part of the modifications to the Greek Seismic Code EAK 2000 (EAK 2003). This map, which followed the catastrophic earthquakes that hit the country between 1978 and 2001, includes three seismic hazard zones with peak ground acceleration (PGA) ranging between 0.16 and 0.36 g. In this paper, following the significant progress ...

5. Learning Informative Health Indicators Through Unsupervised Contrastive Learning 

   Rombach, Katharina; Michau, Gabriel; Burzle, Wilfried; et al. (2024)

   IEEE Transactions on Reliability

   Monitoring the health of complex industrial assets is crucial for safe and efficient operations. Health indicators that provide quantitative real-time insights into the health status of industrial assets over time serve as valuable tools for, e.g., fault detection or prognostics. This article proposes a novel, versatile, and unsupervised approach to learn health indicators using contrastive learning, where the operational time serves as ...
