title: Amplification of Negative Gas Adsorption in a multivariate framework

description: The approach of multivariate MOFs was used to fine-tune the mechanical properties of the flexible framework DUT-49. In situ XRD, NMR and physisorption studies showed that the partial incorporation of a more rigid linker into DUT-49 framework enables a stabilization of the metastable open pore phase which led to a twofold amplification of the expelled gas amount upon “Negative Gas Adsorption” transition.

title: Colloidal probe atomic force microscopy measurements on pristine gas bubbles, agglomerates and particle-laden gas bubbles

description: This dataset contains experimental Atomic Force Microscopy (AFM) force-displacement measurements of poorly wetted alumina particles (colloidal probes) &lt; 15 µm interacting with pristine gas bubbles, agglomerates and particle-laden gas bubbles (hetero-coagulates) in an aqueous environment. The data was generated in the context of the Collaborative Research Center CRC 920 (Project ID 169148856 – subproject B04) that is funded by the German Research Foundation (DFG). The data set is of interest for researches that study the agglomeration or hetero-coagulation in liquid environment, and it is expected to be of particular interest to those that are concerned with the simulation and modeling of these processes (for example by Discrete Element Method). The AFM raw data was baseline corrected to increase the accessibility of the data sets to those less familiar with the AFM. A detailed interpretation of the AFM data in this repository is found in https://doi.org/10.1021/acs.langmuir.3c01781 and https://doi.org/10.1016/j.colsurfa.2024.134660.

title: "Computational Homogenisation and Multiscale Modelling Employing an Image-based Approach for the Structural Analysis of Shells." - Data corresponding to publication

description: This contribution contains the data for the presented numerical examples in the dissertation "Computational Homogenisation and Multiscale Modelling Employing an Image-based Approach for the Structural Analysis of Shells." by L. Mester (2024). Abstract of dissertation: "Shell structures represent efficient structural systems. Integrating materials with distinct properties, such as composites, can further enhance the structural performance of shells. These composite shell structures find application in various engineering fields, ranging from aerospace to civil engineering, providing a balance between strength and material consumption. Identifying the optimum designs, particularly in terms of load-bearing capacity and suitability, drives the need for accurate and efficient analysis methods accounting for the intricate material behaviour of composites. In the scope of this work, a first-order homogenisation method for the analysis of shell structures, taking into account a detailed description of the microstructure, is proposed. The method allows the simulation of the structural behaviour at different length scales within a single framework. Thus, providing an approach able to capture the microscopic morphology while being computationally efficient. Although homogenisation methods are widely used and thoroughly investigated for three-dimensional problems, their application to structural elements, such as shells, still poses challenges. Specifically, assessing the homogenised shear stiffness often yields inaccurate results. The main focus is on the coupling of the microscopic representative volume element (RVE) to the macroscopic shell formulation. For this purpose, three different boundary conditions for the RVE are presented. These differ mainly in the treatment of the macroscopic shear strain and impose different symmetry requirements on the RVE. Introducing an additional constraint at the microscopic scale corrects the homogenised shear stiffness components. Using linear-elastic benchmark examples, the approach is validated at the microscopic scale and further evaluated using multiscale examples, including geometrical and physical nonlinearities. In the context of civil engineering, the proposed method is applied to examine carbon reinforced concrete shell structures. Image-based methods are used to capture the microscopic structure with high accuracy. The aim of this work is to combine a numerical analysis method with an accurate internal description to allow for the evaluation of novel production techniques and structural designs of, but not limited to, carbon-reinforced concrete shell structures."

description: Dieser Datensatz enthält die Rohdaten zur Dissertation "Kinetische Studie der Umbenetzungsagglomeration als Basis für die zweidimensionale formselektive Trennung von Partikelgemischen". Um Partikelgemische hinsichtlicher ihrer Primärpartikelform mit Hilfe der Umbenetzungsagglomeration trennen zu können, muss der Prozess in der Benetzungsphase abgebrochen werden. Um diesen Zeitpunkt bestimmen zu können, kann das Rührerdrehmoment genutzt werden, da damit die Prozesskinetik in-line bestimmt werden kann. Um diese Annahme zu beweisen, wurden zu unterschiedlichen Zeitpunkten Proben aus der Umbenetzungsagglomeration entnommen und mittels Mikroröntgentomographie (µ-CT) und dreidimensionaler Bildverarbeitung analysiert. Die Agglomeratgröße am Ende des Prozesses wurde mit zweidimensionaler Bildverarbeitung bestimmt.

title: Datasets for paper "ReACKed QUICer: Measuring the Performance of Instant Acknowledgments in QUIC Handshakes"

description: This dataset contains Qlog and packet captures to measure the Performance of Instant Acknowledgements in (i) an emulated testbed and (ii) CDNs. See https://doi.org/10.5281/zenodo.13743301 Abstract: In this paper, we present a detailed performance analysis of QUIC instant ACK, a standard-compliant approach to reduce waiting times during the QUIC connection setup in common CDN deployments. To understand the root causes of the performance properties, we combine numerical analysis and the emulation of eight QUIC implementations using the QUIC Interop Runner. Our experiments comprehensively cover packet loss and non-loss scenarios, different round trip times, and TLS certificate sizes. To clarify instant ACK deployments in the wild, we conduct active measurements of 1M popular domain names. For almost all domain names under control of Cloudflare, Cloudflare uses instant ACK, which in fact improves performance. We also find, however, that instant ACK may lead to unnecessary retransmissions or longer waiting times under some network conditions, raising awareness of drawbacks of instant ACK in the future.

title: Longitudinal Concrete Analysis Data

description: The "Longitudinal Concrete Analysis" dataset contains ultrahigh-speed image sequences of concrete surface cylinders under compression testing in a split Hopkinson pressure bar (SHPB) setup, captured with a Kirana7M camera at frame rates between 1 million and 2 million frames per second (Mfps). A Bézier fitting filtering method has been applied to the raw images to correct for inherent image lag errors of the Kirana7M, enabling proper material analysis based using one-dimensional wave theory. The primary use of this dataset is to estimate the longitudinal wave propagation velocity during the first stress wave transit, achieved through the development of an image-sequence-based approach for selecting stress-wave-induced motion points. Additionally, the dataset is used for the estimation of various material properties, including global deformation, concrete velocity, strain, and stress. Strain measurements obtained through the well-established strain gauge technique—commonly used in split Hopkinson bar testing for material analysis—are also provided within the dataset, for validation of the ultrahigh-speed image sequence analysis.
