Pro Memoria of Wilhelm Wortmann
No full textThe author of this report, Wilhelm Wortmann (born November 20, 1797 in Elberfeld, died August 6, 1882 in Dusseldorf) had been one of the deputy mayors in Dusseldorf since 1848 and was a member of the administrative council of the Allgemeine Musikverein, founded in 1845, where he functioned as recording secretrary. In addition, he was second oboist of the society's orchestra. This circumstance could have a personal note, since Wortmann was not a professional musician but one of the "dilletantes" whom Schumann disliked having in the orchestra.Robert Schumann was the director of the Allgemeine Musiverein [General Music Society] at Dusseldorf from 1850 until the end of 1853 (de jure until the end of 1854), conducting the orchestra and the chorus. He was also the municipal music director. Nearly from the beginning there were conflicts between the Society and Schumann. In his second year, he had a stormy confrontation with the deputy mayor Wilhelm Wortmann who was also a leading member of the council of the Allgemeine Musikverein. Schumann's health deteriorated during 1852 and especially the fall of 1853. Things got worse when members of the chorus and orchestra were dissatisfied with Schumann's style of conducting and refused to perform under his direction. Schumann was for his part dissatisfied with the skills of some instrumentalists and singers. In addition, Schumann failed (or refused) to appear at a concert on November 10, 1853. In a letter to the administrative council of the Society dated November 1853, Schumann accuses the council of breach of contract. Mayor Ludwig Hammers tries to mediate between the two parties with a letter dated December 5, 1853. In the end, Schumann terminated his contract in Dusseldorf in October 1854.The paper Pro memoria must have been written between November 19 and Debember 5, 1853. It was written to clarify the situation between the Society and its director and then delievered to the members of the town council of Dusseldorf. At the end of the report, Wormann mentions the letter from Schumann dated November 19 (page 43 of the Pro memoria, line 13-16). A copy of the Pro memoria was most probably sent to Schumann on Debember 5, 1853 from Mayor Hammers, along with a letter in which he asks for Schumann's comment on the reported events.There is another copy of this report held by the Stadtarchiv Dusseldorf (Town Archive Dusseldorf). There are two possibilities for the relationship the two documents. First, the Rice University copy could be a copy of the one held by the Town Archive Dusseldorf. Second, both could be a copy of another exemplar. The later seems likely. Both copies have mistakes in writing that are held in common. There are marks in the Rice copy made in pencil. It is unclear who made them. However, all of the are at parts of the text that report negatively on Robert Schumann. They stem from a member of the town council, from a member of the music society, or from later owners

CFD ANALYSIS OF AIR FLOW AROUND THE ROTOR OF A 1 kW WORTMANN WINDTURBINE
No full textU diplomskom radu je provedena CFD analiza strujanja zraka oko rotora vjetroturbine snage 1 kW koja je oblikovana Wortmannovim aeroprofilima. Nakon analize strujanja zraka oko rotora, napravljena je usporedba s vjetroturbinom koja je izrađena od Althausovih aeroprofila čija je autorica kolegica Mihaela Erceg.
Ograničenja koja su postavljena autoru su snaga rotora vjetroturbine koja mora biti 1 kW i aeroprofili koji moraju biti oznake Wortmann.
Uzimajući u obzir ograničenja, kreće se u prelimirarnu fazu osnivanja i razvoja vjetroturbine iz koje se oblikuje geometrija konačnog seta aeroprofila. Sljedeća faza je oblikovanje geometrije u odgovarajućem softveru platforme Ansys. Zatim slijedi generiranje mreže vodeći računa o graničnom sloju. Nakon svega slijedi CFD simulacija u rješavaču Fluent na temelju čijih rezultata se vrši usporedba polja fizikalnih veličina kod dvije različite vjetroturbine i donosi se konačan zaključak po pitanju efikasnosti.
Na kraju su navedeni prijedlozi za poboljšanje procesa osnivanja i razvitka vjetroturbine.In this master’s thesis, a CFD analysis of wind flow around 1 kW wind turbine rotor defined by Wortmann airofils was conducted. After wind flow analysis around wind turbine rotor, a comparison was made with the windturbine that was made of Althaus airfoils whose author is a colleague Mihaela Erceg.
Limits set up upon author were the power of a windturbine rotor which is 1 kW and airfoils which must be a Wortmann brand.
Regarding the limits, the development starts with the preliminary phase of establishing and developing windturbine which is a start point for modelling the final set of airfoils. Next step is modelling geometry in a certain software of the platform Ansys. Next comes mesh generation taking into account boundary layer. After all, next comes CFD simulation in solver Fluent whose results are used to compare field of physical quantities for two different windturbines and a final conclusion is made regarding wind turbine efficiency.
Lastly, suggestions for improvement have been made for the process of founding and developing windturbine

Linked RDF graphs of an architectural and structural representation of a timber structure
No full textThis dataset provides a collection of semantically enriched RDF graphs representing both architectural and structural aspects of a timber structure. The data is organized into modular Turtle (.ttl) files and one RIF rule definition (.txt) for reasoning purposes.
Included in the dataset:
Architectural Graph.ttl: Captures the spatial and material characteristics of the architectural model, defined using standard RDF vocabularies.
Structural Graph.ttl: Encodes structural elements and their relationships, including support systems and load-bearing components, structured for semantic querying.
Neutral Building Model (Architectural + Structural).ttl: A consolidated RDF representation integrating architectural and structural elements. All proprietary references (e.g., BHoM) have been removed to ensure vendor neutrality and interoperability. Architectural columns are linked to structural bars, and architectural floors to structural panels. The model is fully queryable using SPARQL and adheres to open-access, GDPR-compliant standards.
RDF_RIF_Rule.pie.txt: A rule expressed in RDF/RIF Core syntax that demonstrates reasoning capabilities on the dataset.
This dataset supports the findings of a related journal paper (currently under submission) and is complemented by a GitHub repository containing the scripts and tools used to generate the RDF data. It is intended for researchers and professionals working on Linked Building Data, semantic modeling, ontology design, and integrated architectural/structural workflows in BIM.
All files are formatted using open standards (RDF, Turtle, RIF) and designed for use in FAIR-compliant, interdisciplinary design environments
AEC Co-design workflow for cross-domain querying and reasoning using Semantic Web Technologies
No full textThe Architecture, Engineering, and Construction (AEC) industry faces data integration challenges due to fragmented silos and diverse data representations, hindering cross-domain queries and early detection of design constraints. Semantic Web Technologies (SWTs) address data integration challenges.This paper evaluates the impact of SWTs on co-design workflows by comparing them with alternative approaches to assess their effectiveness in supporting interdisciplinary collaboration and design constraint detection. Using Design Science Research, a co-design methodology is developed that integrates SWTs with AEC tools for reasoning and federated querying. A component of this methodology is a bidirectional mapping strategy for translating object-oriented data models, demonstrated with the Building Habitat Object Model (BHoM), an AEC interoperability framework.Findings reveal that integrating SWTs enables reasoning and complex queries across federated datasets, improving co-design efficiency. These findings support AEC professionals in advancing co-design and data-driven decision-making, while also informing future research on integrating SWTs into AEC design workflows
BHoM to bhOWL converter
No full textThe dataset is the release version v2.0.0 of the BHoM to bhOWL converter, which helps convert BHoM data to a knowledge graph in any software BHoM supports.
BHoM (The Buildings and Habitats object Model) is collaborative framework that runs within several AEC design software, which helps to represent data in a object oriented database model.
OWL (Web Ontology Language) provides a standardized and expressive language for representing knowledge and relationships within a domain. It allows for the creation of ontologies, which are formal descriptions of the concepts and relationships within a domain. Additionally, OWL can support reasoning and inference over ontologies, allowing for automated reasoning about the relationships between different concepts and data elements. This can be particularly useful in identifying inconsistencies or gaps in data, or in suggesting additional data sources or mappings that may be needed to support integration efforts.
Our BHoM to bhOWL converter is developed as an extension to BHoM framework, and runs within any software that BHoM supports (eg. Grasshopper 3D, Excel, etc.)
The dataset contains also example Grasshopper 3D files that exemplify the process of converting BHoM data to bhOWL
Magnetic Multilayers: From High-Throughput Ab-initio Calculations to Predictive Machine Learning
No full textThin-film multi-layer systems of 3d transition metals exhibiting magnetic phenomena are prototype systems in the field of surface magnetism [1,2]. The possibility to tune the interactions by choosing different elements and different stacking, enables scientists and engineers to design materials with specific desired magnetic properties. Up to now, the magnetic properties are rarely examined using high-throughput simulations due to the peculiarities of the setup and technical challenges induced by the surface setup in DFT [3] calculations.We performed a combinatorics study of such multilayer surface systems by employing a layer swapping based approach using three different mono-atomic 3d transition metal layers on noble metal (FCC) substrates. Hence, we systematically constructed symmetric thin-films and computed the resulting magnetic properties. By using a highly automated AiiDA [4,5] workflow and our all-electron full-potential DFT code FLEUR [3] we studied 6660 possible configurations of film systems. This systematic approach enables us to perform a detailed analysis of the underlying physics, magnetic properties as well as to apply ML and XAI techniques on the acquired data. Concluding, we demonstrate the capabilities of state-of-the-art computational frameworks [4,5,6] and workflows [7] in high-throughput materials screening.Acknowledgement: This work was performed as part of the Helmholtz School for Data Science in Life, Earth and Energy (HDS-LEE) and received funding from the Helmholtz Association of German Research Centres.

E.T.A. Hoffmanns »Kater Murr«
No full textWith the ‘Lebens-Ansichten des Katers Murr nebst fragmentarischer Biographie des Kapellmeister Johannes Kreisler in zufälligen Makulaturblättern’ (1819/1921), E.T.A. Hoffmann, the author, composer, illustrator and legal scholar, created a piece of writing that can be considered one of the most groundbreaking novels of the 19th century. This volume assembles new readings that examine Hoffmann's Kater Murr from comparative, musicological and theatre theory perspectives. It also explores poetological (for Kater Murr that means consistently focusing on the materiality of its artistic production) as well as media-aesthetic and cultural studies approaches. With contributions by Prof. Dr. Lutz Ellrich, Prof. Dr. Achim Geisenhanslüke, Dr. Irmtraud Hnilica, Dr. Vanessa Höving, Prof. Dr. Claudia Liebrand, Prof. Dr. Christine Lubkoll, Prof. Dr. Frederike Middelhoff, Prof. Dr. Harald Neumeyer, Prof. Dr. Marion Schmaus, Prof. Dr. Monika Schmitz-Emans, Dagmar Wahl and Prof. Dr. Thomas Wortmann.PublishedE.T.A. Hoffmann, der Autor, Komponist, Zeichner und Jurist, hat mit den „Lebens-Ansichten des Katers Murr nebst fragmentarischer Biographie des Kapellmeister Johannes Kreisler in zufälligen Makulaturblättern“ (1819/1921) einen Text vorgelegt, der als einer der innovativsten Romanprojekte des 19. Jahrhunderts anzusehen ist. Der Band versammelt neue Lektüren, die Hoffmanns Kater Murr aus komparatistischer, musik- und theatertheoretischer Sicht in den Blick nehmen. Sowohl poetologische (das heißt für den Kater Murr immer auch auf die Materialität der künstlerischen Produktion zielende) als auch medienästhetische und kulturwissenschaftliche Zugänge werden erprobt.
