Aeroelastic analysis of wind turbines under turbulent inflow conditions See

The aeroelastic response of a 2 MW NM80 turbine with a rotor diameter of 80 m and interaction phenomena are investigated by the use of a high-fidelity model. A time-accurate unsteady fluid–structure interaction (FSI) coupling is used between a computational fluid dynamics (CFD) code for...

Laserstrahlschweißen von Metallen mit unterschiedlichen thermophysikalischen Eigenschaften See

Im Rahmen dieser Arbeit wurden prozessangepasste Strategien für die gezielte Energieeinbringung beim Laserstrahlschweißen von Metallen mit unterschiedlichen thermophysikalischen Eigenschaften untersucht und entwickelt. Die Umsetzung wurde anhand der Beispiele des Laserstrahlschweißens von Nickelschaum an Nickelblech und ...

Gendo-Frobenius algebras and comultiplication See

Two large classes of algebras, Frobenius algebras and gendo-symmetric algebras, are characterised by thenexistence of a comultiplication with some special properties. Symmetric algebras are both Frobenius and gendo-symmetric. Kerner and Yamagata investigated two variations of gendo-symmetric algebras and i...

Multiscale modelling and simulation of metal fatigue and its applications See

Multiscale materials modelling (MMM) has been recently growing and simultaneously becoming a significant tool for understanding complexities of contemporary materials as well as a valuable driver for their development. In view of that, this work presents a MMM approach based on the appl...

Algorithmen zur nichtlinearen Stabilitätsanalyse dünnwandiger Strukturen See

Diese Arbeit befasst sich mit der direkten Berechnung kritischer Punkte dünnwandiger Strukturen, die durch eine von außen aufgebrachte Knotenverschiebung belastet sind. Hierfür werden die für Kraftlastfälle bereits verfügbaren Algorithmen zur direkten Berechnung von Durchschlags- und Verzweigungspunkten erweitert&#x...

Prosodic event detection for speech understanding using neural networks See

Additive manufacturing of β-tricalcium phosphate components via Fused Deposition of Ceramics (FDC) See

Das Paper beschreibt die Compoundierung bioaktiver Keramik (Beta-Tricalciumphosphat) in einer organischen Matrix, die anschließende Extrusion zu Filamenten, die für den FDM-3D-Druck geeignet sind, sowie die Formgebund zu Scaffolds mittels additiver Fertigung. Weiterhin werden fertigungsprozessbegleitende Untersuchungen z...

PFG-NMR studies of ATP diffusion in PEG-DA hydrogels and aqueous solutions of PEG-DA polymers See

Adenosine triphosphate (ATP) is the major carrier of chemical energy in cells. The diffusion of ATP in hydrogels, which have a structural resemblance to the natural extracellular matrix, is therefore of great importance to understand many biological processes. In continuation of our rec...

Automatisierte Aggregation von Musterimplementierungen See

Christopher Alexander publizierte 1977 erste Muster (Patterns) für die Stadt- und Gebäudearchitektur. Mittlerweile sind Muster in der Softwarearchitektur und -entwicklung etabliert und weitverbreitet. Muster beschreiben abstrakte und bewährte Lösungen für wiederkehrende Problemstellungen. Im Fall von Architekturentwürfen...

A methodology to estimate flow duration curves at partially ungauged basins See

The flow duration curve (FDC) of streamflow at a specific site has a key role in the knowledge on the distribution and characteristics of streamflow at that site. The FDC gives information on the water regime, providing information to optimally manage the water resources of&#x...

Using software-performance-antipatterns and profiling traces to perform code-refactorings See

Today, usability, user satisfaction, as well as enterprise adoption of a software application, are highly influenced by the performance of the software application. Therefore, it is required to resolve performance issues as early as possible during the development of the software. Many ...

A collaborative pattern writing platform See

Nowadays, two types of approaches are used to formulate and publish patterns. On the one hand, patterns are formulated by a group of authors and are published in a printed medium. Hence no feedback is provided outside of the author group unless they approach other authors...

Plant detection and classification in agricultural fields See

Field game herbs like the field larkspur provide a food source for animals e.g. bees, especially during their blooming period. This plant species is weak in competition for nutrients, thus it does not decrease crop yield. Nevertheless, the field larkspur is destructed by the f...

Carbon flow assessment and analysis in European countries: potential benefits of CO2-efficient Demand Response programs in interconnected electricity markets See

The CO2 emission intensity of electricity use in a country is determined by the combination of generation technologies used to satisfy the demand. In an interconnected electricity network, imports and exports between countries can be a significant contributor to the combination. In this...

High-level rovibrational calculations on ketenimine See

From an astrochemical point of view ketenimine (CH2CNH) is a complex organic molecule (COM) and therefore likely to be a building block for biologically relevant molecules. Since it has been detected in the star-forming region Sagittarius B2(N), it is of high relevance in this ...
