For this purpose, it gathers on a dedicated repository (Zenodo), data from several high-contrast ground-based instruments worldwide in which we injected synthetic planetary signals. The data challenge is hosted on the CodaLab competition platform, where participants can upload their results. The specifications of the data challenge are published on our website https://exoplanet-imaging-challenge.github.io/. The first phase, launched on the 1st of September 2019 and closed on the 1st of October 2020, consisted in detecting point sources in two types of common data-set in the field of high-contrast imaging: data taken in pupil-tracking mode at one wavelength (subchallenge 1, also referred to as ADI) and multispectral data taken in pupil-tracking mode (subchallenge 2, also referred to as ADI+mSDI). In this paper, we describe the approach, organisational lessons-learnt and current limitations of the data challenge, as well as preliminary results of the participants’ submissions for this first phase. In the future, we plan to provide permanent access to the standard library of data sets and metrics, in order to guide the validation and support the publications of innovative image processing algorithms dedicated to high-contrast imaging of planetary systems.

It is intended that this addendum will be merged with RR-335 in the future as a report for predicting the sound insulation in buildings using mass-timber constructions including NLT assemblies. This report presents the results from experimental studies of airborne sound transmission through assemblies of nail-laminated timber (NLT) with various linings. To put the data presented in this report in the proper context, this report begins with a brief explanation of calculation procedures to predict the apparent sound transmission class (ASTC) between adjacent spaces in a building whose structure is a combination of mass-timber assemblies such as nail-laminated timber (NLT) or cross-laminated timber (CLT) panels.

The CBRN GSR currently in use by the CAF is the C4 respirator. The National Research Council of Canada assessed the communication performance of the C4 respirator. This report presents the results of the performance test. The method for assessing the communication performance used in this study was the NIOSH standard test procedure TEB-CBRN-APR-STP-0313 [1]. Other methods exist to evaluate the communication performance of respirators, but historically the NIOSH standard test procedure has been used. This report details the implementation and results of the tests conducted at the National Research Council of Canada, following the NIOSH standard test procedure.

Especially in the automotive industry, the reliable supply of painted bodies for the fi nal assembly is essential for OEMs considering just in time or just in sequence processes. Additionally one central cost target is the avoidance of resorting for JIT/JIS processes. An essential workfl ow analysis is therefore the basis for making strategic or operational decisions such as the adjustment of the plant structure or increasing the number of products and variants manufactured simultaneously. In order to support strategic planning using simulation and planning systems, the modeling of the production process is required. This is particularly important for scheduling as no real manufacturing data is available and therefore prognosis based on the model are essential. Due to the short time and the limited human resources for a detailed modeling, it is essential to create a robust model with good accuracy and reduced complexity Y1 - 2014 SN - 978-3-936527-38-4 U6 - https://doi.org/10.15771/978-3-936527-38-4 SP - 35 EP - 43 S PB - News & Media ER - TY - JOUR A1 - Lautenschläger, Toni A1 - Leis, Alexander A1 - Dendorfer, Sebastian A1 - Palm, Christoph A1 - Schreiner, Rupert A1 - Langer, Christoph A1 - Prommesberger, Christian A1 - Ławrowski, Robert Damian A1 - Dams, Florian A1 - Bornmann, Benjamin A1 - Navitski, Aliaksandr A1 - Serbun, Pavel A1 - Müller, Günter A1 - Liebetruth, Thomas A1 - Kohlert, Dieter A1 - Pernsteiner, Jochen A1 - Schreier, Franz A1 - Heerklotz, Sabrina A1 - Heerklotz, Allwin A1 - Boos, Alexander A1 - Herwald, Dominik A1 - Monkman, Gareth J.

Standardized procedures for calculating the overall transmission, combined with standardized measurements to characterize sub-assemblies, provide much better prediction of sound transmission between adjacent indoor spaces. The International Standards Organization (ISO) has published a calculation method, ISO 15712-1 that uses laboratory test data for sub-assemblies such as walls and floors as inputs for a detailed procedure to calculate the expected sound transmission between adjacent rooms in a building. This standard works very well for some types of construction, but to use it in a North American context one must overcome two obstacles – incompatibility with the ASTM standards used by our construction industry, and low accuracy of its predictions for lightweight wood or steel frame construction. To bypass limitations of ISO 15712-1, this Guide explains how to merge ASTM and ISO test data in the ISO calculation procedure, and provides recommendations for applying extended measurement and calculation procedures for specific common types of construction. This Guide was developed in a project established by the National Research Council of Canada to support the transition of construction industry practice to using apparent sound transmission class (ASTC) for sound control objectives in the National Building Code of Canada (NBCC). However, the potential range of application goes beyond the minimum requirements of the NBCC – the Guide also facilitates design to provide enhanced sound insulation, and should be generally applicable to construction in both Canada and the USA. This publication contains a limited set of examples for several types of construction, to provide an introduction and overview of the ASTC calculation procedure. Additional examples and measurement data can be found in the companion documents to this Guide, namely NRC Research Reports RR-333 to RR-337. Furthermore, the calculation procedure outlined and illustrated in this Guide is also used by the software web application soundPATHS, which is available for free on the website of the National Research Council of Canada (see the references in Section 7 of this Guide for access details). Au cours des dernières années, les scientifiques et les ingénieurs ont fait porter leurs efforts en matière d’atténuation de la transmission du son dans les bâtiments davantage sur le rendement du système dans sa totalité que sur les ensembles de construction individuels. Les méthodes normalisées de calcul de la transmission globale, combinées à des mesures normalisées de caractérisation des sous-ensembles, permettent de mieux prédire la transmission du son entre des espaces intérieurs adjacents. L’Organisation internationale de normalisation (ISO) a publié une méthode de calcul, la norme ISO 15712-1, qui utilise des données d’essai en laboratoire pour les sous-ensembles, comme les murs et les planchers, comme données d’entrée en vue d’une méthode détaillée de calcul de la transmission du son prévue entre des pièces adjacentes dans un bâtiment. Cette norme fonctionne très bien pour certains types de construction, mais pour l’utiliser dans un contexte nord-américain, il faut surmonter deux obstacles – l’incompatibilité avec les normes ASTM utilisées par notre industrie de la construction et la faible exactitude de ses prévisions pour la construction à ossature de bois ou d’acier légère. Pour contourner les limites de la norme ISO 15712-1, le présent guide explique comment fusionner les données d’essai de l’ISO et de l’ASTM dans la méthode de calcul de l’ISO, et formule des recommandations relativement à l’application de méthodes élargies de mesure et de calcul pour des types de construction courants. Le présent guide a été élaboré dans le cadre d’un projet mis sur pied par le Conseil national de recherches du Canada afin d’appuyer la transition de la pratique de l’industrie de la construction vers l’utilisation d’un indice de transmission du son apparent (ITSA) satisfaisant aux objectifs de réduction rigoureux du Code national du bâtiment du Canada (CNBC). Toutefois, l’éventail potentiel d’applications va au-delà des exigences minimales du CNBC – le Guide facilite aussi une conception visant à améliorer l’insonorisation et devrait s’appliquer de façon générale à la construction tant au Canada qu’aux États-Unis. La présente publication contient un ensemble limité d’exemples pour plusieurs types de construction, afin de fournir une introduction et un aperçu de la méthode de calcul de l’ITSA. On trouvera d’autres exemples et données de mesure dans les documents d’accompagnement du présent guide, à savoir, les rapports de recherche RR-333 à RR-337 du CNRC. De plus, la méthode de calcul décrite et illustrée dans le présent guide est également utilisée par l’application Web soundPATHS, disponible gratuitement sur le site Web du Conseil national de recherches du Canada (voir les références à la section 7 du présent guide pour les détails d’accès).

Here, we propose a toolbox to validate MR-AC of clinical PET/MRI data sets. Methods Torso scans of ten patients were acquired on a combined PET/CT and on a 1.5-T MRI system. MR-based attenuation data were derived from the CT following MR–CT image co-registration and subsequent histogram matching. PET images were reconstructed after CT- (PET/CT) and MR-based AC (PET/MRI). Lesion-to-background (L/B) ratios were estimated on PET/CT and PET/MRI. Results MR–CT histogram matching leads to a mean voxel intensity difference in the CT- and MR-based attenuation images of 12% (max). Mean differences between PET/MRI and PET/CT were 19% (max). L/B ratios were similar except for the lung where local misregistration and intensity transformation leads to a biased PET/MRI. Conclusion Our toolbox can be used to study pitfalls in MR-AC. We found that co-registration accuracy and pixel value transformation determine the accuracy of PET/MRI.
