Optical fibers guide light in a central core surrounded by a cladding. The most common fibers are step-index fibers, which guide light using total internal reflection in the fiber core. Recently, a new class of fibers, with a microstructured cladding, which also include photonic&#x...

In der Blechumformung besteht derzeit ein verstärktes Interesse an der Reduktion bzw. Vermeidung von mineralölbasierten Schmierstoffen. Neben ökonomischen Faktoren liegt das Anliegen zum Verzicht auf mineralölbasierte Schmierstoffe vor allem in ökologischen Aspekten begründet. Ein vollständig neuer Forschungsansatz&...

Digital Personal Assistant like the offerings from major tech companies like Amazon, Apple, and Google are seeing increased adoption rates as they near the end of their first decade of existence. Despite the backing of these companies, theses assistants remain restricted in the typ...

Internet of Things (IoT) is not just a word now. With an estimated 30 billion devices in the world by 2020, IoT has already become what it was envisioned when the trend began. But there is still a hustle from companies around the world for better and better ...

Permafrost covers over 60% of the territory in the central Siberia region. In recent years, there has been growing evidence to suggest that the runoff in central Siberia has shown an increase. This is suspected to be associated with the permafrost thawing in central Siberia.&#...

Durch die voranschreitende Digitalisierung der Gesellschaft sind Unternehmen mehr denn je zuvor in der Lage personenbezogene Daten im Internet zu erfassen, ohne dass Verbraucher dies mitbekommen. Es reicht schon das Besuchen einer Webseite mit angemeldeten Kundenkonto aus, um seine Daten preiszug...

The ring-opening polymerization (ROP) of (hetero)cyclic monomers provides access to a multitude of industrially important polymers such as poly(ester)s or poly(ether)s. In this context, meticulously designed catalysts with imposing ligand systems often feature the best performance of the abundantly av...

Cellular dynamics are modeled by the 3D architecture and mechanics of the extracellular matrix (ECM) and vice versa. These bidirectional cell‐ECM interactions are the basis for all vital tissues, many of which have been investigated in 2D environments over the last decades. Experimental...

This study underlines the relevance of leaching of fly ash particulate matter to carbon capture plants and strives for a better understanding of the solubility of various elements and heavy metals, especially Fe, in MEA solutions and of relevant leaching parameters.

This thesis investigates the possibility to reduce the computational effort of a dynamic skeletal muscle model making use of model order reduction methods. For that purpose, a three-dimensional, nonlinear, dynamic skeletal muscle model based on the theory of incompressible finite hyperelasticity&...

This thesis presents a full set of new numerical approaches for the description of nonlinear phenomena within nanostructures. Additionally, these methods are used to calculate second- and third-harmonic generations as well as the Kerr optical effect within nanostructures of different shapes. ...

Diese Arbeit beschäftigt sich damit die Stabilität und Funktionstüchtigkeit des Antriebsstranges einer Windenergieanlage der Größenordnung 10 MW zu untersuchen. Hierfür erfolgt der Aufbau eines Computermodells einer 10-MW-Windenergieanlage mithilfe des Mehrkörpersimulationsprogrammes SIMPACK. Weiterhin wird eine Parameterstud...

A great variety of commercially available goods, e. g. food products, require a degree of protection against gases and vapors. Electronic devices whose active layers are based on organic materials in particular demand extremely low oxygen transmission rates in order to attain adequate&#...
