Atomistic Simulations of Crack Front Curvature Effects and Crack-Microstructure Interactions
(2017)
The resistance against crack propagation is undoubtedly one of the most important properties of metallic materials. Particularly in the early stage of their existence, the growth of cracks is influenced by interactions ...
Performance Engineering for Exascale-Enabled Sparse Linear Algebra Building Blocks
(2018)
The increasing demand for solving larger and more complex problems in computational science and engineering is a major driving factor to deploy computer systems with ever-advancing performance capabilities. To increase the ...
Wideband Active Load Modulation in RF Power Amplifiers
(2019)
For almost a century, active load modulation techniques have been used to increase the backoff efficiency of high frequency power amplifiers. The Doherty architecture, which is based on active load modulation, has become ...
Super Cartan geometry and loop quantum supergravity
(2022)
Superstring theory and loop quantum gravity (LQG) are promising approaches towards the formulation of a quantum theory of gravity. Superstring theory aims at unification of all fundamental forces of nature, predicting ...
Entropically driven self‐assembly of pear‐shaped nanoparticles
(2020)
The ambition to recreate highly complex and functional nanostructures found in living organisms marks one of the pillars of today‘s research in bio- and soft matter physics. Here, self-assembly has evolved into a prominent ...

Electric power systems are pioneers and drivers of prosperity in modern societies. In this respect, they play a key role worldwide in achieving climate goals, electrifying connecting renewable energies. The entire energy ...
Sound emission of low-pressure axial fans under distorted inflow conditions
(2018)
The sound emission of low-pressure axial fans is substantially influenced by the fan blade geometry and the inflow conditions, induced by the fan installation system. However, the combined impact of these parameters has ...
Characterization and Design of Small Array Antennas for Direction-Of-Arrival Estimation Characterization and Design of Small Array Antennas for Direction-Of-Arrival Estimation for Ultra-Wideband Industrial FMCW Radar Systems
(2015)
This book covers the characterization and design of small array antennas for ultra-wideband (UWB) industrial linear frequency-modulated continuouswave (FMCW) RADAR systems. Although the techniques developed in this work ...
A Hierarchical Control Architecture for ω-Languages
(2017)
In the Supervisory Control Theory according to P.J. Ramadge und W.M. Wonham, the behaviour of a dynamical system is described by sequences of discrete events. Typical applications are production and transportation systems ...
Morphometry of random spatial structures in physics
(2016)
From the large-scale structure of the universe to exotic states in nuclear matter: random or disordered spatial structures appear on nearly all length scales in very different physical, chemical, or biological systems. In ...
Physically-Based Methodology for the EMC-Compliant Design and Verification of Automotive System ICs
(2021)
In the recent decades, automotive electronics has undergone a rapid evolution towards highly complex multifunction chips. So-called Automotive System ICs can integrate multiple DC/DC-converters, a logic core, linear ...
Fracture Toughness of Freestanding Metallic Thin Films Studied by Bulge Testing
(2018)
Metallic thin films are nowadays frequently used as key components in microelectronic and microelectromechanical systems, so that the functionalities of these systems often depend on the structural integrity of the ...
Backstepping Control of Coupled Parabolic Systems with Varying Parameters
(2021)
Many technical processes are described by coupled parabolic partial differential equations. Time dependent characteristics, time-varying spatial domains or the linearization of a system around a desired trajectory result ...
