Forecasting methods for the datasets of Covid 19 for Sachsen and Czechia
No full textThis project consists of forecasting methods for the datasets of Covid 19 for Sachsen and Czechia, and the associated data. In a live setting it is automatically updated via a CI/CD pipeline (e.g. GitLab), and uploaded to a database that can be then accessed by a webserver backend, or a similar data consumer. This dataset has served as a basis for Where2Test website forecast dashboards for Sachsen and Czechia
Automatic deployment scripts for Covidsim/Episim web visualizer
No full textoai:rodare.hzdr.de:2351These scripts perform post-processing tasks of data produced by the Episim simulation framework on a HPC cluster, and facilitate automated upload of the post-processed data to a webserver running the Covidsim visualizer. Authentication is based on SSH keys, and the upload itself can be triggered either via a cronjob on the webserver, or via a git hook initiated by an external CI/CD pipeline (e.g. GitLab)
High Field Suppression of Bremsstrahlung Emission in High-Intensity Laser-Plasma Interactions
No full textThis dissertation investigates the effect of macroscopic electric and magnetic fields on bremsstrahlung emission in high-intensity laser-plasma interactions, specifically in the regime of relativistic-induced transparency. The Particle-in-Cell (PIC) EPOCH simulation code has been updated to incorporate a new suppression mechanism influenced by the presence of intense electric and magnetic fields. The study compared the bremsstrahlung emissions generated under relativistic transparency conditions using three distinct models: the original bremsstrahlung model in the EPOCH code, the model modified by the magnetic suppression (MS) effect, and the newly proposed suppression model by the electric and magnetic suppression (EMS) effect.
The results demonstrated that macroscopic electric and magnetic fields have a significant effect on the decrease of bremsstrahlung photons in laser-plasma interactions. In addition, differences in electron dynamics were observed between the EPOCH and EMS models, indicating that the suppression mechanism can influence the dynamics of electron acceleration. The study provides insight into bremsstrahlung emission under extreme conditions, where energetic electrons travel through a relativistically transparent plasma while being deflected by magnetic fields with MT-level strength.
On the basis of the results, it is suggested that the implementation of conventional bremsstrahlung in PIC codes be modified to account for the discussed suppression effect
Multi-sensor spectral database of WEEE polymers
No full textPolymers represent around 25% of total waste from electronic and electric equipment. Any successful recycling process must ensure that polymer-specific functionalities are preserved, to avoid downcycling. This requires a precise characterization of particle compounds moving at high speeds on conveyor belts in processing plants. We present a multi-sensor database including spectra acquired from imaging and point measurement sensors on 23 polymers including ABS, PS, PC, PE-types, PP, PVC, PET-types, PMMA, and PTFE. The techniques applied include hyperspectral imaging sensors (HSI) to map reflectance in the visible to near infrared (VNIR, (350–1000) nm ), short-wave (SWIR, (1000–2500) nm) and mid-wave infrared (MWIR, (2500–5000) nm) as well as point Raman, FTIR and portable spectral spectroradiometer (PSR) instruments.This research activity was supported by EIT RawMaterials within the KAVA up-scaling project "RAMSES-4-CE" (19262). We thank The Helmholtz Institute Freiberg for Resource Technology for supporting and funding the project for the AisaFENIX sensor. We acknowledge the HighSpeedImaging project, Funded by the European Regional Development Fund and the Land of Saxony, for the SPECIM FX50 sensor
HZDR Data Management Strategy — Top-Level Architecture
No full textThis data publication contains an overview to the Top-Level Architecture of the proposed HZDR Data Management Strategy with additional description of the various systems and services.
The Helmholtz-Zentrum Dresden-Rossendorf (HZDR) pursues a comprehensive data management strategy that is designed as an architecture of services to describe and manage scientific experiments in a sustainable manner. This strategy is based on the FAIR principles and aims to ensure the findability, accessibility, interoperability and reusability of research data.
The HZDR's comprehensive data lifecycle covers all phases of the data lifecycle: from planning and collection to analysis, storage, publication and archiving. Each phase is supported by specialised services and tools that help scientists to efficiently collect, store and share their data. These services include:
Electronic lab notebook: for the digital recording and management of lab experiments and data.
Data management plans (RDMO): For planning and organising data management during a research project.
(Time Series) Databases: For structured storage and retrieval of research data.
File systems: For storing and managing files in a controlled environment.
Publication systems (ROBIS, RODARE): For the publication and accessibility of research data and results.
Metadata catalogue (SciCat): For describing data in a wide variety of subsystems using searchable metadata
Repositories (Helmholtz Codebase): For archiving, version control and provision of software, special data sets and workflows.
Proposal Management System (GATE): For the administration of project proposals and approvals.
The superordinate web service HELIPORT plays a central role here. HELIPORT acts as a gateway and connecting service that links all components of the Data Management Strategy and describes them in a sustainable manner. HELIPORT ensures standardised access to the various services and tools, which considerably simplifies collaboration and the exchange of data

C++ & Python API for Scientific I/O with openPMD
No full textopenPMD is an open metadata format for open data workflows in open science. This library provides a common high-level API for openPMD writing and reading. It provides a common interface to I/O libraries and file formats such as HDF5 and ADIOS. Where supported, openPMD-api implements both serial and MPI parallel I/O capabilities.Supported by the Exascale Computing Project (17-SC-20-SC), a collaborative effort of two U.S. Department of Energy organizations (Office of Science and the National Nuclear Security Administration). Supported by the CAMPA collaboration, a project of the U.S. Department of Energy, Office of Science, Office of Advanced Scientific Computing Research and Office of High Energy Physics, Scientific Discovery through Advanced Computing (SciDAC) program. Previously supported by the Consortium for Advanced Modeling of Particles Accelerators (CAMPA), funded by the U.S. DOE Office of Science under Contract No. DE-AC02-05CH11231. This work was partially funded by the Center of Advanced Systems Understanding (CASUS), which is financed by Germany's Federal Ministry of Education and Research (BMBF) and by the Saxon Ministry for Science, Culture and Tourism (SMWK) with tax funds on the basis of the budget approved by the Saxon State Parliament
