Hydrogeophysik : Erkundungen und Sicherung der Ressource Wasser : Antrittsvorlesung 2006-06-01
(2006)
Die weltweite Wasserversorgung basiert zu einem überwiegenden Teil auf Grundwasser. Die Erkundung, der Schutz, die nachhaltige Nutzung sowie die eventuelle Sanierung dieser Grundwasserressourcen sind somit global von fundamentalem gesellschaftlichem Interesse. Bei vielen dieser grundwasserbezogenen Fragestellungen ist häufig eine effiziente und detaillierte Charakterisierung des Untergrundes notwendig. Geophysikalische Messverfahren liefern Abbilder der physikalischen Eigenschaften, wie beispielsweise des elektrischen Widerstandes, die wichtige Informationen über den geometrischen und stofflichen Aufbau des verborgenen Untergrundes liefern. In der Vorlesung wird gezeigt, wie die Verfahren der Angewandten Geophysik auf Fragestellungen hinsichtlich der Präsenz, Ausbreitung und Qualität der Ressource Grundwasser eingesetzt werden können. Darüber hinaus werden aktuelle Forschungsthemen und offene Fragen angesprochen.
Python is used in a wide range of geoscientific applications, such as in processing images for remote sensing, in generating and processing digital elevation models, and in analyzing time series. This book introduces methods of data analysis in the geosciences using Python that include basic statistics for univariate, bivariate, and multivariate data sets, time series analysis, and signal processing; the analysis of spatial and directional data; and image analysis. The text includes numerous examples that demonstrate how Python can be used on data sets from the earth sciences. The supplementary electronic material (available online through Springer Link) contains the example data as well as recipes that include all the Python commands featured in the book.
MATLAB is used in a wide range of applications in geosciences, such as image processing in remote sensing, generation and processing of digital elevation models and the analysis of time series. This book introduces basic methods of data analysis in geosciences using MATLAB. The text includes a brief description of each method and numerous examples demonstrating how MATLAB can be used on data sets from earth sciences. All MATLAB recipes can be easily modified in order to analyse the reader's own data sets. The book comes with a CD containing exemplary data sets and a digital version of the MATLAB recipes.

In this study we examine the tonal organization of a series of recordings of liturgical chants, sung in 1966 by the Georgian master singer Artem Erkomaishvili. This dataset is the oldest corpus of Georgian chants from which the time synchronous F0-trajectories for all three voices have been reliably determined (Müller et al. 2017). It is therefore of outstanding importance for the understanding of the tuning principles of traditional Georgian vocal music.
The aim of the present study is to use various computational methods to analyze what these recordings can contribute to the ongoing scientific dispute about traditional Georgian tuning systems. Starting point for the present analysis is the re-release of the original audio data together with estimated fundamental frequency (F0) trajectories for each of the three voices, beat annotations, and digital scores (Rosenzweig et al. 2020). We present synoptic models for the pitch and the harmonic interval distributions, which are the first of such models for which the complete Erkomaishvili dataset was used. We show that these distributions can be very compactly be expressed as Gaussian mixture models, anchored on discrete sets of pitch or interval values for the pitch and interval distributions, respectively. As part of our study we demonstrate that these pitch values, which we refer to as scale pitches, and which are determined as the mean values of the Gaussian mixture elements, define the scale degrees of the melodic sound scales which build the skeleton of Artem Erkomaishvili’s intonation. The observation of consistent pitch bending of notes in melodic phrases, which appear in identical form in a group of chants, as well as the observation of harmonically driven intonation adjustments, which are clearly documented for all pure harmonic intervals, demonstrate that Artem Erkomaishvili intentionally deviates from the scale pitch skeleton quite freely. As a central result of our study, we proof that this melodic freedom is always constrained by the attracting influence of the scale pitches. Deviations of the F0-values of individual note events from the scale pitches at one instance of time are compensated for in the subsequent melodic steps. This suggests a deviation-compensation mechanism at the core of Artem Erkomaishvili’s melody generation, which clearly honors the scales but still allows for a large degree of melodic flexibility. This model, which summarizes all partial aspects of our analysis, is consistent with the melodic scale models derived from the observed pitch distributions, as well as with the melodic and harmonic interval distributions. In addition to the tangible results of our work, we believe that our work has general implications for the determination of tuning models from audio data, in particular for non-tempered music.

Die Ziele der Energiewende sind ehrgeizig. Der Vortrag zeigt, welche Nutzungsoptionen der Untergrund bietet - z.B. geothermische Energiegewinnung oder geologische Speicherung. Für eine gesellschaftsweite, sachliche Diskussion werden konkrete Zahlen nicht nur zu den Chancen, sondern auch zu den Risiken benötigt.
Frank Krüger, der seit 1997 am Institut für Geowissenschaften in der Seismologie tätig ist, wurde eine außerplanmäßige Professur für Geophysik übertragen. Seine Vorlesung zum Thema "Seismologische Arrays in der teleseismischen Struktur- und Herdprozessabbildung" gibt einen Überblick über den Einsatz arrayseismologischer Verfahren in der Erdstrukturerkundung und der detaillierten Abbildung von Erdbebenherden. Dichte Netzwerke von seismologischen Messstationen ermöglichen die Anwendung spezieller hochauflösender Auswertungsverfahren. Diese wurden zunächst im Kontext der Spionage entwickelt, finden heutzutage aber breite Anwendung in vielen seismologischen Forschungsbereichen, von der Erkundung der Struktur an der Grenze zum Erdkern, über Zusammenhänge von seismischem Wellenfeld und Wetterphänomenen bis hin zum Einsatz bei Tsunamifrühwarnsystemen zur schnellen Analyse sehr großer Erdbebenherde.

"In spite of ever-increasing research into natural hazards, the reported damage from natural disasters continues to rise, increasingly disrupting human activities. We, as scientists who study the way in which the part of Earth most relevant to society- the surface-behaves, are disturbed and frustrated by this trend. It appears that the large amounts of funding devoted each year to research into reducing the impacts of natural disasters could be much more effective in producing useful results. At the same time we are aware that society, as represented by its decision makers, while increasingly concerned at the impacts of natural disasters on lives and economies, is reluctant to acknowledge the intrinsic activity of Earth's surface and to take steps to adapt societal behaviour to minimise the impacts of natural disasters. Understanding and managing natural hazards and disasters are beyond matters of applied earth science, and also involve considering human societal, economic and political decisions"

Theories and concepts
(2020)
Urban Change and Citizenship in Times of Crisis addresses the fact that in the beginning of the twenty-first century the majority of the world’s population is urbanised, a social fact that has turned cities more than ever into focal sites of social change. Multiple economic and political strategies, employed by a variety of individual and collective actors, on a number of scales, constitute cities as contested spaces that hold opportunities as well as restrictions for their inhabitants. While cities and urban spaces have long been of central concern for the social sciences, today, classical sociological questions about the city acquire new meaning: Can cities be spaces of emancipation, or does life in the modern city entail a corrosion of citizenship rights? Is the city the focus of societal transformation processes, or do urban environments lose importance in shaping social reality and economic relationships? Furthermore, new questions urgently need to be asked: What is the impact of different historical phenomena such as neo-liberal restructuring, financial and economic crises, or migration flows, as well as their respective counter-movements, on the structure of contemporary cities and on the citizenship rights of city inhabitants? The three volumes address such crucial questions thereby opening up new spaces of debate on both the city and new developments of urbanism.
The contributions to Theories and Concepts offer new theoretical reflections on the city in a philosophical and historical perspective as well as fresh empirical analyses of social life in urban contexts. Chapters not only critically revisit classical and modern philosophical considerations about the nature of cities but no less discuss normative philosophical reflections of urban life and the role of religion in historical processes of the emergence of cities. Composed around the question whether there can be such a thing as a ‘successful city’, this volume addresses issues of urban political subjectivities by considering the city’s role in historical processes of emancipation, the fight for citizenship rights, and today’s challenges and opportunities with regard to promoting social justice, integration, and diversity. Consequentially, theory-driven empirical analyses offer new insight into ways of solving problems in urban contexts and a genuine approach to analyse the Social Quality in cities.

Alexander von Humboldt
(2022)
This book aims to view and to understand Alexander von Humboldt from different perspectives and in varying disciplinary contexts. His contributions addressed numerous topics in the earth but also life sciences—spanning from geo-botany, climatology, paleontology, oceanography, mineralogy, resources, and hydrogeology to links between the environmental impact of humans, erosion, and climate change. From the very beginning, he paved the way for a modern, integrated earth system science approach to decipher, characterize, and model the different forcing factors and their feedback mechanisms. It becomes obvious that Humboldt’s holistic approach is far beyond simple description and empiric data collection. As documented and analyzed in the different texts of this volume, he combines observation and analysis with emotions and subjective perceptions in a very affectionate way. However, this publication does not intend to add another encyclopedic text compilation but to observe and critically analyze this unique personality´s relevance in a modern context, particularly in discussing environmental and social key issues in the twenty-first century.
