Preferential Solvation in Carbonyl-Twisted PRODAN Derivatives
No full textThe
Rosés and Bosch model for preferential solvation is
used to analyze the fluorescence behavior of two PRODAN derivatives
in binary solvents with one or two protic components. The preferential
solvation results suggest that the excited PRODAN derivatives form
two H-bonds. The model allows for determining the characteristics
of the singly H-bonded excited states. They show red-shifted fluorescence
but relatively little quenching. In contrast, the doubly H-bonded
excited states are significantly quenched when the protic solvent
is a strong H-bond donor (large SA value). With two protic solvents
there is little preferential interaction even though the solvents
have very different H-bond-forming ability

Emil Fahrenkamp: Bauten und Projekte für Berlin
No full textThema der vorliegenden Arbeit ist die umfassende Aufarbeitung und Dokumentation der Bauten und Projekte Emil Fahrenkamps (*1885, 1966) in Berlin und Potsdam-Babelsberg sowie die kritische Einordnung seiner Arbeiten in den Kontext der Baugeschichte des 20. Jahrhunderts. Den zentralen Untersuchungsgegenstand bildet, neben der gebaudespezifischen Erfassung der Bau- und Planungsprozesse und der Gebaudebeschreibung Fahrenkamps grosstadtische Arbeiten und Entwurfe in ihrem gesellschaftlichen Kontext zu analysieren. Zeitlich umfasst die Arbeitsphase Fahrenkamps in Berlin die Jahre zwischen 1920 und 1945, in denen er seine bauliche Aktivitaten sowohl fur private Bauherrn als auch fur offentliche Auftraggeber etablieren und ausbauen konnte. Emil Fahrenkamp galt bisher als ein Vertreter der Moderne in Deutschland. Dieses fest gefugte Bild entstand durch die einseitige Gleichsetzung seiner Architektur mit dem Shell-Haus, das in den Jahren 192932 nach seinen Planen in Berlin errichtet wurde und das zur Ikone grosstadtischen Bauens in der baugeschichtlichen Bewertung geworden ist. Die vorliegende Arbeit sucht diese Sicht auf Emil Fahrenkamp kritisch zu hinterfragen und zu differenzieren. Indem sie exemplarisch seine Arbeiten fur Berlin aufarbeitet, gelingt eine neue Sicht seiner architektonischen Intention und damit eine Neubewertung seiner Bedeutung in der deutschen Baugeschichte des 20. Jahrhunderts.Architectur

Choral Works of Emil Hradecký
No full textThis thesis deals with the figure of contemporary Czech composer Emil Hradecký with a special respect to choral compositions. In the first chapter the author introduces Emil Hradecký as a mUSlC teacher, composer and publisher. In the following chapter she describes Hradecký's music work in general, inc1uding his methodological handbooks and instructive pieces. The core of the thesis is the part which focuses on Hradecký's choral works. It contains a complete list of his choral works and analysis of several works which il1ustrate his various compositional styles. The significance of this thesis is in its survey of Hradecký's choral works, especially due to the fact that a monograph about this composer has not been published yet. The author hopes that this thesis might contribute to extending of the general knowledge about this composer
A computational non-commutative geometry program for disordered topological insulators
No full textThis work presents a computational program based on the principles of non-commutative geometry and showcases several applications to topological insulators. Noncommutative geometry has been originally proposed by Jean Bellissard as a theoretical framework for the investigation of homogeneous condensed matter systems. Recently, this approach has been successfully applied to topological insulators, where it facilitated many rigorous results concerning the stability of the topological invariants against disorder. In the first part of the book the notion of a homogeneous material is introduced and the class of disordered crystals defined together with the classification table, which conjectures all topological phases from this class. The manuscript continues with a discussion of electrons’ dynamics in disordered crystals and the theory of topological invariants in the presence of strong disorder is briefly reviewed. It is shown how all this can be captured in the language of noncommutative geometry using the concept of non-commutative Brillouin torus, and a list of known formulas for various physical response functions is presented. In the second part, auxiliary algebras are introduced and a canonical finite-volume approximation of the non-commutative Brillouin torus is developed. Explicit numerical algorithms for computing generic correlation functions are discussed. In the third part upper bounds on the numerical errors are derived and it is proved that the canonical-finite volume approximation converges extremely fast to the thermodynamic limit. Convergence tests and various applications concludes the presentation. The book is intended for graduate students and researchers in numerical and mathematical physics
