Advances in Spacecraft Attitude Control
Spacecraft attitude maneuvers comply with Euler's moment equations, a set of three nonlinear, coupled differential equations. Nonlinearities complicate the mathematical treatment of the seemingly simple action of rotating, and these complications lead to a robust lineage of research. This book is meant for basic scientifically inclined readers, and commences with a chapter on the basics of spac…

Advances in Modelling and Control of Wind and Hydrogenerators
Rapid deployment of wind and solar energy generation is going to result in a series of new problems with regards to the reliability of our electrical grid in terms of outages, cost, and life-time, forcing us to promptly deal with the challenging restructuring of our energy systems. Increased penetration of fluctuating renewable energy resources is a challenge for the electrical grid. Proposing …

EIB Working Paper 2022/02 - How to foster climate innovation in the European …
Relying on the EIB Online Survey on Climate Innovations, we investigate the different climate innovations European firms are currently using, their motivations and challenges, and their views on current regulatory frameworks. The analysis confirms that there’s a strong link between climate innovation and firm performance, but also that firms suffer from the low availability of finance. To cre…

EIB Group Carbon Footprint Report 2020
This report provides a comprehensive breakdown of EIB Group greenhouse gas emissions arising from internal operations at head office locations in 2020. It also analyses comparatively against performance in previous years dating back to the 2007 baseline. As a result of the teleworking arrangements during the COVID-19 pandemic, the EIB Group’s net emissions in 2020 were more than 70% below 201…

Terra Petraea
Situated in a deep valley and flanked by high mountain ranges, Petra's urban development was only possible through a well-structured organization of its surrounding landscape. This study presents a first comprehensive archaeological and culture-historical characterization of the Petraean hinterland and researches overall strategies of the spatial organization of the city's rural environs. Ba…

Study of an alternative phase field model for low interfacial energy in elast…
In 2005, the hybrid model was published by Prof. H.-D. Alber and Prof. P. Zhu as an alternative to the Allen-Cahn model for the description of phase field transformations. With low interfacial energy, it is more efficient, since the resolution of the diffuse interface is numerically broader for the same solution accuracy and allows coarser meshing. The solutions of both models are associated wi…

Speech perception in complex acoustic environments
Listeners with hearing impairments have difficulties understanding speech in the presence of background noise. Although prosthetic devices such as hearing aids and cochlear implants may improve the hearing capability, listeners with hearing impairments still complain about their speech perception in the presence of noise. The basic tonal audiometry only gives a cursory idea of the degree of dif…

Providing orbit information with predetermined bounded accuracy
The exchange of orbit information is becoming more important in view of the increasing population of objects in space as well as the increase in parties involved in space operations. The aim of this thesis was to investigate how orbit information maintained by a space surveillance system can be provided to its users. Services like collision avoidance require very accurate information, while oth…

On the Stability of Objective Structures
The main focus of this thesis is the discussion of stability of an objective (atomic) structure consisting of single atoms which interact via a potential. We define atomistic stability using a second derivative test. More precisely, atomistic stability is equivalent to a vanishing first derivative of the configurational energy (at the corresponding point) and the coerciveness of the second deri…
