Das neue fib Bulletin 80 : Teilsicherheitsbeiwerte fĂŒr die Nachrechnung bestehender Massivbauwerke
Die zuverlÀssigkeitsbasierte Nachrechnung bestehender Tragwerke
kann auf Basis verschiedener wissenschaftlicher Verfahren
erfolgen. Da jedoch bisher nur wenige mit den Eurocodes
kompatible Verfahren fĂŒr eine praxisgerechte Anwendung
existieren, kommen fĂŒr die Nachrechnung bestehender Tragwerke
meist semiprobabilistische Verfahren und Teilsicherheitsbeiwerte
zur Anwendung, wie sie auch zur Bemessung
von Neubauwerken verwendet werden. Eine solche Beurteilung
bzw. Nachrechnung bestehender Tragwerke fĂŒhrt oft zu
sehr konservativen Ergebnissen, verbunden mit aufwendigen
und kostenintensiven VerstĂ€rkungsmaĂnahmen.
Vor diesem Hintergrund wurde in der fib Task Group 3.1 âReliability
and safety evaluation: full-probabilistic and semi-probabilistic
methods for existing structuresâ das neue Bulletin 80
âTeilsicherheitsbeiwerte fĂŒr die Nachrechnung bestehender
Massivbauwerkeâ [1] erarbeitet, welches sowohl Empfehlungen
fĂŒr die Teilsicherheitsbeiwerte der Einwirkungs- als auch
der Widerstandsseite enthÀlt.
Im vorliegenden Beitrag werden neben zwei Verfahren zur Bestimmung
modifizierter Teilsicherheitsbeiwerte fĂŒr die Nachrechnung
bestehender Massivbauwerke nach fib Bulletin 80 [1]
mit schwerpunktmĂ€Ăiger Betrachtung der Widerstandsseite
auch Methoden zur Anpassung des ZielzuverlÀssigkeitsindex
nach fib Bulletin 80 [1] vorgestellt. DarĂŒber hinaus wird das
Vorgehen an einem Anwendungsbeispiel erlÀutert
Simulation-based roadmap for the integration of poly-silicon on oxide contacts into screen-printed crystalline silicon solar cells
We present a simulation-based study for identifying promising cell structures, which integrate poly-Si on oxide junctions into industrial crystalline silicon solar cells. The simulations use best-case measured input parameters to determine efficiency potentials. We also discuss the main challenges of industrially processing these structures. We find that structures based on p-type wafers in which the phosphorus diffusion is replaced by an n-type poly-Si on oxide junction (POLO) in combination with the conventional screen-printed and fired Al contacts show a high efficiency potential. The efficiency gains in comparsion to the 23.7% efficiency simulated for the PERC reference case are 1.0% for the POLO BJ (back junction) structure and 1.8% for the POLO IBC (interdigitated back contact) structure. The POLO BJ and the POLO IBC cells can be processed with lean process flows, which are built on major steps of the PERC process such as the screen-printed Al contacts and the Al2O3/SiN passivation. Cell concepts with contacts using poly-Si for both polarities (POLO 2-concepts) show an even higher efficiency gain potential of 1.3% for a POLO 2 BJ cell and 2.2% for a POLO 2 IBC cell in comparison to PERC. For these structures further research on poly-Si structuring and screen-printing on p-type poly-Si is necessary. © 2021, The Author(s)
For none, one, or two polaritiesâHow do POLO junctions fit best into industrial Si solar cells?
We present a systematic study on the benefit of the implementation of poly-Si on oxide (POLO) or related junctions into p-type industrial Si solar cells as compared with the benchmark of Passivated Emitter and Rear Cell (PERC). We assess three aspects: (a) the simulated efficiency potential of representative structures with POLO junctions for none (=PERC+), one, and for two polarities; (b) possible lean process flows for their fabrication; and (c) experimental results on major building blocks. Synergistic efficiency gain analysis reveals that the exclusive suppression of the contact recombination for one polarity by POLO only yields moderate efficiency improvements between 0.23%abs and 0.41%abs as compared with PERC+ because of the remaining recombination paths. This problem is solved in a structure that includes POLO junctions for both polarities (POLO2), for whose realization we propose a lean process flow, and for which we experimentally demonstrate the most important building blocks. However, two experimental challengesâalignment tolerances and screen-print metallization of p+ poly-Siâare unsolved so far and reduced the efficiency of the ârealâ POLO2 cell as compared with an idealized scenario. As an intermediate step, we therefore work on a POLO IBC cell with POLO junctions for one polarity. It avoids the abovementioned challenges of the POLO2 structure, can be realized within a lean process flow, and has an efficiency benefit of 1.59%abs as compared with PERCâbecause not only contact recombination is suppressed but also the entire phosphorus emitter is replaced by an n+ POLO junction
Examining meandering stream by using geomorphological characteristics with GIS-based analysis
An assessment of the meandering stream type using its classification system to geomorphology characteristics combined with GIS-based analysis is presented in this paper. It describes geomorphology characteristics consisting of 8 parameters with GIS-based analysis that differ in the zone of sediment position, stream width, stream sinuosity, amplitude, wavelength, bend sharpness, meander pattern, and slope. The selected case study in this paper is the Barito Stream, South Kalimantan, Indonesia. Based on the results, the variability varied in all the geomorphology characteristics except bend sharpness and slope. The transport zone is the longest zone with classified as a very wide river with moderate sinuosity and high amplitude (< 1500). It is also categorized as a moderate wavelength and sharp bend with a relatively shallow slope. This approach is a simple, appropriate, and easy-to-use practice in examining meandering stream since there is no data or lack of supporting field data. The implementation of this meandering stream classification method is suitable for stream restoration projects, fish habitat enhancement, and water resource management. Further research is the study of possible geomorphic responses of a channel to natural and anthropogenic disturbances including channel-bed degradation, channel-bed aggradation, channel widening, and channel straightening
Vestibular Infant Screening (VIS)âFlanders : results after 1.5Â years of vestibular screening in hearing-impaired children
Due to the close anatomical relationship between the auditory and vestibular end organs, hearing-impaired children have a higher risk for vestibular dysfunction, which can affect their (motor) development. Unfortunately, vestibular dysfunction often goes unnoticed, as vestibular assessment in these children is not standard of care nowadays. To timely detect vestibular dysfunction, the Vestibular Infant ScreeningâFlanders (VISâFlanders) project has implemented a basic vestibular screening test for hearing-impaired infants in Flanders (Belgium) with a participation rate of 86.7% during the first year and a half. The cervical Vestibular Evoked Myogenic Potentials (cVEMP) test was applied as vestibular screening tool to map the occurrence of vestibular (mainly saccular) dysfunction in this population. At the age of 6 months, 184 infants were screened. No refers on vestibular screening were observed in infants with permanent conductive hearing loss. In infants with permanent sensorineural hearing loss, a cVEMP refer rate of 9.5% was observed. Failure was significantly more common in infants with severe-profound compared to those with mild-moderate sensorineural hearing loss (risk ratioâ=â9.8). Since this is the first regional study with a large sample size and successful participation rate, the VISâFlanders project aims to set an example for other regions worldwide
The Science Performance of JWST as Characterized in Commissioning
This paper characterizes the actual science performance of the James Webb
Space Telescope (JWST), as determined from the six month commissioning period.
We summarize the performance of the spacecraft, telescope, science instruments,
and ground system, with an emphasis on differences from pre-launch
expectations. Commissioning has made clear that JWST is fully capable of
achieving the discoveries for which it was built. Moreover, almost across the
board, the science performance of JWST is better than expected; in most cases,
JWST will go deeper faster than expected. The telescope and instrument suite
have demonstrated the sensitivity, stability, image quality, and spectral range
that are necessary to transform our understanding of the cosmos through
observations spanning from near-earth asteroids to the most distant galaxies.Comment: 5th version as accepted to PASP; 31 pages, 18 figures;

The James Webb Space Telescope Mission
Twenty-six years ago a small committee report, building on earlier studies,
expounded a compelling and poetic vision for the future of astronomy, calling
for an infrared-optimized space telescope with an aperture of at least .
With the support of their governments in the US, Europe, and Canada, 20,000
people realized that vision as the James Webb Space Telescope. A
generation of astronomers will celebrate their accomplishments for the life of
the mission, potentially as long as 20 years, and beyond. This report and the
scientific discoveries that follow are extended thank-you notes to the 20,000
team members. The telescope is working perfectly, with much better image
quality than expected. In this and accompanying papers, we give a brief
history, describe the observatory, outline its objectives and current observing
program, and discuss the inventions and people who made it possible. We cite
detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space
