The treatise is about the co-incineration of waste-derived fuels and raw materials in clinker/cement production plants and its impact on emissions to air. Depending on the incineration conditions, emissions to air can exceed existing requirements. This is demonstrated and explained by b...

In this work, new experimental methods and techniques for the analysis of the microscopic and the micromechanical material behavior of nickel- and iron-based superalloys are developed with the emphasis on the material characteristics and processes at smallest length scales.

The demand for cloud services is rising continuously, inflating the energy demand for data centres exponentially. The purpose of this literature review is to discover the positive impact liquid immersion cooling can have on data centre efficiency and density. Utilizing a systematic lite...

The use of electric vehicles has gained momentum in recent times as they prove to be eco-friendly and energy-efficient. EVs offer a long-term solution to reduce the dependence on fossil fuels and greenhouse gas emission. Decreased air pollution due to the elimination of the ex...

This thesis contains (i) experimental and (ii) numerical techniques to improve the description of fracture. In terms of (i), we provide validation data for high-velocity impact which were extracted by a software which we designed for this purpose. The algorithms to process the moti...

Thermochemical energy storage (TCS) constitutes a promising concept to exploit reaction enthalpies for the storage of thermal energy, which offers great potential for the development of more efficient storage solutions with higher energy densities compared to sensible and latent thermal energy&#x...

Das Haus, die Tradition und das Glück; die drei charakteristischen Termini dieser Forschung stehen explizit und markant in ihrer direkten Aneinanderreihung und sollen als Hyperonyme einer Metaebene für den folgenden Diskurs dienen. Diese setzt sich mit der Wechselbeziehung und Symbiose dieser...

Lignocellulosen, insbesondere heimische Laubhölzer wie Buche oder Pappel, bieten großes Potenzial als nachhaltige Rohstoffquelle für eine chemisch-stoffliche Verwertung. Insbesondere das enthaltene Lignin ist durch sein aromatisches Grundgerüst dafür prädestiniert. Um dieses zugänglich zu machen, muss das verholzte&...

Wave equations are usually simulated using explicit time integration methods. But the strong restriction on time step sizes in media with large differences in wave speeds can lead to high computational cost. Implicit time integration methods on the other hand can achieve better sta...

The field of Lexical Semantic Change Detection (LSCD) deals with the detection of words that change their meaning over time. While there is a large amount of research in the field, only few go beyond a standard benchmark evaluation of existing models. The goal of this...

A lot of problems in Imitation Learning can be split into multiple low-level tasks that need to be executed in sequence or parallel. Likewise in the area of human motion prediction, the actions of the human are frequently defined by a combination of linked subgoals. Howev...

Dieser SISS-Beitrag fasst die Ergebnisse aus dem DFG-geförderten Projekt „Monte-Carlo-Simulationen zur Evaluation der Leistungsfähigkeit moderner Missing Data Techniken bei Schätzung von Strukturgleichungsmodellen mit latenten Variablen. Eine systematische Analyse verschiedener Varianten der Multiplen Imputation“ zusammen. Im...

Quantum computers in this day and age are characterized by high error rates and their limited amount of qubits. This introduces errors to the execution of quantum circuits. Consequently, quantum computers currently cannot be expected to run arbitrary circuits successfully. In this conte...

A group corresponds to a topological space with one nontrivial homotopy group. A crossed module corresponds to a topological space with two nontrivial homotopy groups. In classical group theory, Cayley's Theorem constructs for every group G an injective group morphism to the symmetr...

To improve the representativeness of a real microstructural cut-out for modeling purposes, a numerical method named as “boundary pixel color alteration (BPCA)” is presented to modify measured 2D microstructure cut-outs. Its physical background is related to the phase growth. For the applicat...

In der heutigen Zeit haben Menschen viel mehr Zugriff auf Daten innerhalb eines Tages, als früher die meisten in ihrer gesamten Lebenszeit. Problematisch hierbei ist, dass diese Daten in verschiedensten Formen und Formaten gespeichert sind und somit das Verständnis der Beziehung zwischen...
