title: Erklärung des Verhaltens des Wasserdampfes aus der Wirksamkeit der van der Waalschen Kräfte und der Bildung von Doppel- und Mehrfachmolekülen

description: Das besondere thermodynamische Verhalten des Wasserdampfes wird mit Hilfe der Assoziationstheorie quantitativ erklärt. Dabei wird angenommen, daß zwischen den H2O-Molekülen neben den in normalen Gasen vorhandenen Kräften zusätzliche Kräfte kurzer Reichweite wirken, die zur Bildung von verschieden großen Molekülkomplexen führen. Der Anteil der normalen Kräfte und der Assoziationskräfte an der Abweichung des Wasserdampfes vom idealen Verhalten wird mit Hilfe gewisser Annahmen abgeschätzt. Die Anzahlen der nach diesen Annahmen in einem Volumen vorhandenen verschieden großen Molekülkomplexe werden für einen großen Zustandsbereich als Funktion des spezifischen Volumens und der Temperatur berechnet. Betrachtungen über die Struktur der Komplexe zeigen, daß man sie sich als von molekülartiger Struktur mit schwacher Bindung vorstellen kann, wobei sich die Bindungsenergie angeben läßt. Die Theorie führt zu einer thermischen Zustandsgleichung, die das Verhalten des Wasserdampfes in einem großen Bereich und bis in die Nähe des kritischen Punktes gut wiedergibt.
description: The special thermodynamic behaviour of water vapour is quantitatively explained by the theory of association. It is assumed that there are additional forces of short range beside those, which exist in normal gases. These additional forces cause the formation of molecular complexes of various size. The influence of the normal forces and the forces of association on the deviation of steam from the ideal behaviour is estimated by certain assumptions. The quantities of the various molecular complexes existing according to these assumptions in a volume unity are calculated for a large range of state as a function of specific volume and temperature. Considerations about the structure of the complexes show, that they can be thought to be of molecule-like structure with weak bonds. Under these conditions the binding energy can be determined. The theory leads to an equation of state, which represents well the behaviour of steam within a wide range and almost up to the critical point.

description: Cosmic ray (CR) electrons reveal key insights into the non-thermal physics of the interstellar medium, galaxies, galaxy clusters, and active galactic nuclei by means of their inverse Compton γ-ray emission and synchrotron emission in magnetic fields. While magnetohydrodynamical (MHD) simulations with CR protons capture their dynamical impact on these systems, only few computational studies include CR electron physics because of the short cooling time-scales and complex hysteresis effects, which require a numerically expensive, high-resolution spectral treatment. Since CR electrons produce important non-thermal observational signatures, such a spectral CR electron treatment is important to link MHD simulations to observations. We present an efficient post-processing code for Cosmic Ray Electron Spectra that are evolved in Time (CREST) on Lagrangian tracer particles. The CR electron spectra are very accurately evolved on comparably large MHD time steps owing to an innovative hybrid numerical-analytical scheme. CREST is coupled to the cosmological MHD code AREPO and treats all important aspects of spectral CR electron evolution such as adiabatic expansion and compression, Coulomb losses, radiative losses in form of inverse Compton, bremsstrahlung and synchrotron processes, diffusive shock acceleration and reacceleration, and Fermi-II reacceleration. After showing various code validations of idealized one-zone simulations, we study the coupling of CREST to MHD simulations. We demonstrate that the CR electron spectra are efficiently and accurately evolved in shock-tube and Sedov-Taylor blast wave simulations. This opens up the possibility to produce self-consistent synthetic observables of non-thermal emission processes in various astrophysical environments.

description: Auf der Grundlage der klassischen Plattentheorie werden die Möglichkeiten zur Ermittlung der Auflagerkraft-Einflußflächen schiefwinkliger Platten untersucht. Am Beispiel der zweiseitig gelenkig gelagerten Platte mit zwei freien schiefen Rändern wird gezeigt, daß die bisher in der Literatur angegebenen Verfahren hier versagen. Es wird ein geschlossener Ausdruck für die Randquerkraft-Singularität hergeleitet, der in Verbindung mit höheren Singularitäten als Ansatzfunktionen für den regulären Anteil der Einflußfunktion zu brauchbaren Ergebnissen führt.
description: On the basis of the classical theory of plates, the possibilities of calculating influence surfaces for vertical reactions of skew plates are investigated. A plate, which has two simply supported and two free edges and is shaped like a parallelogram, is chosen as an example. In this case, as is shown, the methods mentioned in the literature fail. A rigorous expression for the singularity of the boundary shearing force is developed, thus leading to practical results when higher singularities are used for the regular part of the influence function.

description: We study the stability and breakup of invariant tori in Hamiltonian flows using a combination of Kolmogorov-Arnold-Moser (KAM) theory and renormalization-group techniques. We implement the scheme numerically for a family of Hamiltonians quadratic in the actions to analyze the strong coupling regime. We show that the KAM iteration converges up to the critical coupling at which the torus breaks up. Adding a renormalization consisting of a rescaling of phase space and a shift of resonances allows us to determine the critical coupling with higher accuracy. We determine a nontrivial fixed point and its universality properties.

Reconsidering the Career of the "Artifex" Nicholaus (active. c. 1122- c. 1164) in the Context of Later Twelfth-Century North Italian Politics

description: The present study revises the chronology for the twelfth-century "artifex" Nicholaus, demonstrating that his career began just after c.1122 in Piacenza and ended in Verona c. 1164, not c. 1150 as often proposed.   The first sculpted entranceway with the Nicholaus imprimatur was executed at the Sagra di San Michele.
      It is documented that Nicholaus was put in charge of supervising the construction and decoration of the new cathedral in Ferrara in 1135, including the western entranceway with his self-laudatory signature inscription.  His activity here ended around 1150, at which time the interior of the cathedral was functional.  In the early 1140s, members of the Nicholaus atelier and possibly the "artifex" himself crossed the Alps to execute certain sculptures at the imperial burial church at Königslutter.  The signed Verona Cathedral entranceway was executed in the 1150s.  Work at San Zeno began after 1164: the elegiac tone of two signature inscriptions here seems to indicate that Nicholaus died around this time.
      To determine the date of the Nicholaus Verona projects, given the lack of firm documentary evidence for their dating, because their subject matter could be associated with a known historical incident or situation and those dates fit with my stylistic evaluation as to the sculpture's date, I used the dates for these occurrences as the "termini post quem" for the project.
      Luigi Simeoni had proposed that the formation of the commune of Verona in 1135 is celebrated by the scene on the lunette at San Zeno depicting the patron saint of Verona signing blessing in the midst of the troops.  This supported a date of 1138 for this work.  However, my research into the relationship between Verona and various emperors led me to conclude that the image on the lunette at San Zeno actually memorializes the formation in 1164 of the Veronese League opposing Emperor Frederick  Barbarossa.  A second subject here, The Hunt of Theodoric, seems to have been chosen to insult Barbarossa, previously well received in Verona.  The San Zeno frontispiece with Nicholaus's sculptures, the famous bronze doors, and the Wheel of Fortune window was assembled c.1200.
A simple construction of initial data for multiple black holes

description: We consider the initial data problem for several black holes in vacuum with arbitrary momenta and spins on a three space with punctures. We compactify the internal asymptotically flat regions to obtain a computational domain without inner boundaries. When treated numerically, this leads to a significant simplification over the conventional approach which is based on throats and isometry conditions. In this new setting it is possible to obtain existence and uniqueness of solutions to the Hamiltonian constraint.

Reconfiguring Montcalm Farm: A Prototype for a New Cross-Disciplinary Approach to Preserving Rural Architecture
Creators: Marsh, Michael H.
Publisher: name: Columbia University
Year: 2012
Subjects: subject: Architecture
subject: FOS: Civil engineering

description: At its core, this thesis is an acknowledgment that peri-urban development will always take the most expedient form â€“ most often total architectural and programmatic erasure — unless an alternative approach is demonstrated to be both economically feasible and programmatically desirable by its potential users. The thesis will argue that in rare cases , the architectural vestiges and programmatic legacy of a given site may inherently hold sufficient historic, social, cultural, and/or spatial value so as to be worthy of assimilation and reconfiguration, rather than total replacement. The thesis is explicitly concerned with the vast quantity of rural and vernacular fabric at the periphery of urban and suburban sprawl, which falls outside of the traditional classification of historic structures as defined by the Secretary of the Interior's 'Standards' and is consequently ineligible for state or federal funding, and therefore must fend for itself. Rather than viewing such conditions as unfortunate impediments to the preservation process, the thesis seeks to leverage those very forces which threaten these historic properties as a catalyst for layering a renewed vitality upon such sites. Exploring a primarily obsolete former dairy farm located in northern Virginia as a case study for such conditions, the thesis will argue for an alternative approach to peri-urban development, which negotiates between the two extremes of tabula-rasa razing and embalmed 'ghost town.' Recognizing that the 'dignity' of farmland has always been rooted in its self-sufficiency and productive vitality, a modern program will be proposed for the 225 acre property, which will seek to revitalize the site while maintaining continuity and interaction with its five existing programs, and introduce a new 'economic engine' capable of generating sufficient income to support the continued viability of the property.
Best management practices for whitebark pine management mining and mineral exploration

description: Whitebark pine is a species of five needle pine that is found broaly at high elevations in BC roughly south of the Yellowhead Highway. Within BC the species is currently Blue Listed and in Canada is listed as Endangered indicating a substantial conservation concern, its primary threats are white pine blister rust, mountain pine beetle, fire suppression and climate change. Mining and other industrial activities have the potential to further damage the species through habitat loss yet with good planning may to provide benefits to the long-term survival of the species through the use of best management practices. Key means for the mining sector to create a net-benefit for whitebark pine include funding blister rust screening, seed collections, planting in reclamation and habitat offsetting.

description: Die vorliegende Doktorarbeit ist als kumulative Dissertation aufgebaut und umfasst, nach einer kurzen Einleitung, vier wissenschaftliche Aufsätze. Thematisch befassen sich alle dieser Aufsätze damit, unter welchen Umständen Menschen miteinander kooperieren. Drei davon basieren auf ökonomischen Feldexperimenten, die im Rahmen des SASSCAL-Forschungsprojektes in der Kavango-Region in Namibia durchgeführt wurden. Der Hintergrund der jeweiligen Fragestellungen ist primär die nachhaltige Nutzung natürlicher Ressourcen. Im konkreten Fall handelt es sich dabei um Waldflächen, welche zwecks Landgewinn abgeholzt werden, was langfristig lokale sowie globale negative Externalitäten nach sich zieht. Behandelt werden dabei unter anderem die Fragen, wie sich Ressourcenknappheit auswirkt, wie sich Ressourcennutzungsverhalten durch externe (monetäre) Anreize steuern lässt und ob die bloße Kommunikation zwischen den betroffenen Teilnehmern bereits zu positiven Effekten führt.
description: This dissertation contains, next to an introductory chapter, four single essays. These essays investigate if and how people cooperate with each other. Three of the essays are based on economic field experiments conducted in the Kavango area in Northern Namibia as part of the SASSCAL research project. The research background is the sustainable use of natural resources. In particular, forest areas in the research region are being cleared in order to be converted into agriculturally used land, which does, in the long run, result in negative externalities on both, local and global scale. The principal questions that this thesis investigates are how scarcity affects resource use behavior, how external (monetary) incentives may be suitable as regulative measures and if simple communication between involved parties already results in more positive outcomes.
Kolmogorov-Arnold-Moser Renormalization-Group Approach to the Breakup of Invariant Tori in Hamiltonian Systems

description: We analyze the breakup of invariant tori in Hamiltonian systems with two degrees of freedom using a combination of KAM theory and renormalization-group techniques. We consider a class of Hamiltonians quadratic in the action variables that is invariant under the chosen KAM transformations, following the approach of Thirring. The numerical implementation of the transformation shows that the KAM iteration converges up to the critical coupling at which the torus breaks up. By combining this iteration with a renormalization, consisting of a shift of resonances and rescalings of momentum and energy, we obtain a much more efficient method that allows to determine the critical coupling with high accuracy. This transformation is based on the physical mechanism of the breakup of invariant tori. We show that the critical surface of the transformation is the stable manifold of codimension one of a nontrivial fixed point, and we discuss its universality properties.

description: Magnetic resonance (muSR and NMR) studies of f-electron non-Fermi-liquid (NFL) materials give clear evidence that structural disorder is a major factor in NFL behavior. Longitudinal-field muSR relaxation measurements at low fields reveal a wide distribution of muon relaxation rates and divergences in the frequency dependence of spin correlation functions in the NFL systems UCu_{5-x}Pd_x and CePtSi_{1-x}Ge_x. These divergences seem to be due to slow dynamics associated with quantum spin-glass behavior, rather than quantum criticality as in a uniform system, for two reasons: the observed strong inhomogeneity in the muon relaxation rate, and the strong and frequency-dependent low-frequency fluctuation observed in U(Cu,Pd)_5 and CePt(Si,Ge). In the NFL materials CeCu_{5.9}Au_{0.1}, Ce(Ru_{0.5}Rh_{0.5})_2Si_2, CeNi_2Ge_2, and YbRh_2Si_2 the low-frequency weight of the spin fluctuation spectrum is much weaker than in the disordered NFL systems.

description: We study numerically the fully nonlinear gravitational collapse of a self-gravitating, minimally-coupled, massless scalar field in spherical symmetry. Our numerical code is based on double-null coordinates and on free evolution of the metric functions: The evolution equations are integrated numerically, whereas the constraint equations are only monitored. The numerical code is stable (unlike recent claims) and second-order accurate. We use this code to study the late-time asymptotic behavior at fixed $r$ (outside the black hole), along the event horizon, and along future null infinity. In all three asymptotic regions we find that, after the decay of the quasi-normal modes, the perturbations are dominated by inverse power-law tails. The corresponding power indices agree with the integer values predicted by linearized theory. We also study the case of a charged black hole nonlinearly perturbed by a (neutral) self-gravitating scalar field, and find the same type of behavior---i.e., quasi-normal modes followed by inverse power-law tails, with the same indices as in the uncharged case.

Aus diesem Grunde ist die Kenntnis aller mit dem Einflug und Aufenthalt von Dipteren in Ställen in Zusammenhang stehenden Milieuvoraussetzungen unerläßlich. Die vorliegende Arbeit beschäftigt sich unter Verwendung während der Jahre 1951 bis 1963 erzielter Ergebnisse ganz allgemein mit dem klimatischen Charakter der Einflugbahn und des Stallraumes im Hinblick auf die Einflugbewegung von Dipteren und deren Verteilungsverhalten im Raum unter Berücksichtigung verschiedener Wetterlagen und der bei verschiedenen Stallarten für diesen Fragenkomplex wichtigen Raumbezirke. Diese Ergebnisse stellen die Voraussetzung für eine spezielle Untersuchung des Zusammenhanges zwischen Raumklima und Raumverhalten interessanter oder praktisch wichtiger Dipterenarten dar.
description: In stables more than 300 species of Diptera were found. Some of them may be of hygienic or economic importance. Therefore it is necessary to know all the ecological conditions of the stables as to the way of entrance of the Diptera and their stay in these rooms. Studies about temperature and humidity carried out from 1951 to 1963 showed the common character of these climatological factors in different vertical and horizontal regions of stablerooms and the climatological conditions of the way of entrance. - The results of these studies published here were the base for investigations concerning the relations between the climate of the stablerooms and the distribution of important species of Diptera.

description: Surface acoustic waves (SAWs) strongly modulate the shallow electric potential in piezoelectric materials. In semiconductor heterostructures such as GaAs/AlGaAs, SAWs can thus be employed to transfer individual electrons between distant quantum dots. This transfer mechanism makes SAW technologies a promising candidate to convey quantum information through a circuit of quantum logic gates. Here we present two essential building blocks of such a SAW-driven quantum circuit. First, we implement a directional coupler allowing to partition a flying electron arbitrarily into two paths of transportation. Second, we demonstrate a triggered single-electron source enabling synchronisation of the SAW-driven sending process. Exceeding a single-shot transfer efficiency of 99 %, we show that a SAW-driven integrated circuit is feasible with single electrons on a large scale. Our results pave the way to perform quantum logic operations with flying electron qubits.

We resolve a damped oscillatory component for both La concentrations, indicative of disordered antiferromagnetism. For x = 0.2 the oscillation frequency decreases smoothly with increasing temperature, and vanishes at the specific heat anomaly temperature T* \approx 2.2 K. Our results are consistent with the view that T* is due to a magnetic transition rather than anisotropic Kondo behavior.

Angular Resolution of the LISA Gravitational Wave Detector

description: We calculate the angular resolution of the planned LISA detector, a space-based laser interferometer for measuring low-frequency gravitational waves from galactic and extragalactic sources. LISA is not a pointed instrument; it is an all-sky monitor with a quadrupolar beam pattern. LISA will measure simultaneously both polarization components of incoming gravitational waves, so the data will consist of two time series. All physical properties of the source, including its position, must be extracted from these time series. LISA's angular resolution is therefore not a fixed quantity, but rather depends on the type of signal and on how much other information must be extracted. Information about the source position will be encoded in the measured signal in three ways: 1) through the relative amplitudes and phases of the two polarization components, 2) through the periodic Doppler shift imposed on the signal by the detector's motion around the Sun, and 3) through the further modulation of the signal caused by the detector's time-varying orientation. We derive the basic formulae required to calculate the LISA's angular resolution $ΔΩ_S$ for a given source. We then evaluate $ΔΩ_S$ for two sources of particular interest: monchromatic sources and mergers of supermassive black holes. For these two types of sources, we calculate (in the high signal-to-noise approximation) the full variance-covariance matrix, which gives the accuracy to which all source parameters can be measured. Since our results on LISA's angular resolution depend mainly on gross features of the detector geometry, orbit, and noise curve, we expect these results to be fairly insensitive to modest changes in detector design that may occur between now and launch. We also expect that our calculations could be easily modified to apply to a modified design.

description: In this article, we describe a new renormalization-group scheme for analyzing the breakup of invariant tori for Hamiltonian systems with two degrees of freedom. The transformation, which acts on Hamiltonians that are quadratic in the action variables, combines a rescaling of phase space and a partial elimination of irrelevant (non-resonant) frequencies. It is implemented numerically for the case applying to golden invariant tori. We find a nontrivial fixed point and compute the corresponding scaling and critical indices. If one compares flows to maps in the canonical way, our results are consistent with existing data on the breakup of golden invariant circles for area-preserving maps.

description: Although Gödel's incompleteness theorem made mathematician recognize that no axiomatic system could completely prove its correctness and that there is an eternal hole between our knowledge and the world, physicists so far continue to work on the approaches based on the hypothesis to completely or approximately know the systems of interest. In this paper, however, I review the recent development of a different approach, a statistical theory based upon the notion of incomplete information. This consideration leads to generalized statistical mechanics characterized by an incompleteness parameter which equals unity when information is complete. The mathematical and physical bases of the information incompleteness are discussed. The application of the concomitant incomplete quantum distribution to correlated electron systems is reviewed.

description: The exact general solution to the Einstein equations in a homogeneous Universe with a full causal viscous fluid source for the bulk viscosity index $m=1/2$ is found. We have investigated the asymptotic stability of Friedmann and de Sitter solutions, the former is stable for $m\ge 1/2$ and the latter for $m\le 1/2$. The comparison with results of the truncated theory is made. For $m=1/2$, it was found that families of solutions with extrema no longer remain in the full case, and they are replaced by asymptotically Minkowski evolutions. These solutions are monotonic.

description: The ultrastrong coupling of (quasi-)particles has gained considerable attention due to its application potential and richness of the underlying physics. Coupling phenomena arising due to electromagnetic interactions are well explored. In magnetically ordered systems, the quantum-mechanical exchange-interaction should furthermore enable a fundamentally different coupling mechanism. Here, we report the observation of ultrastrong intralayer exchange-enhanced magnon-magnon coupling in a compensated ferrimagnet. We experimentally study the spin dynamics in a gadolinium iron garnet single crystal using broadband ferromagnetic resonance. Close to the ferrimagnetic compensation temperature, we observe ultrastrong coupling of clockwise and anticlockwise magnon modes. The magnon-magnon coupling strength reaches more than 30% of the mode frequency and can be tuned by varying the direction of the external magnetic field. We theoretically explain the observed phenomenon in terms of an exchange-enhanced mode-coupling mediated by a weak cubic anisotropy.

An innovative approach to monitoring the physical stability of constructed fish habitat using drones

description: In August 2014, a subsurface failure at the Mount Polley mine’s tailings storage facility resulted in a debris flow that scoured Hazeltine Creek and a portion of Edney Creek. Creek rehabilitation planning, design and construction commenced immediately following the incident. A two-phased approach was adopted to reconstruct the creek and restore habitat for fish and riparian wildlife. The first phase was to construct an erosion-resistant engineered channel to control erosion and reduce turbidity in water entering Quesnel Lake. The second phase was to re-establish physical in-stream and riparian habitat along the channel to support a return of biological habitat function. Following the construction of habitat features in sections of Hazeltine Creek and Edney Creek, drone imagery was used to georeference the locations of the constructed habitat. The aerial imagery had sufficient resolution to geospatially document each element of stream habitat, and therefore monitor its physical stability. This novel habitat monitoring technique couples the aerial imagery from drones with geographic information system (GIS) software to reliably determine the stability of each element of habitat and develop a database of those habitat elements. This combination of technologies enables an effective, relatively rapid and low-cost means of monitoring constructed fish habitats.

description: Der Informationswert von Geschäftsdaten in Analytischen Informationssystemen lässt sich durch eine Integration von Geodaten erheblich steigern. In den letzten Jahren entstanden aus diesem Grund vermehrt interdisziplinäre Forschungsbeiträge und Prototypen zur gemeinsamen Analyse von Geschäftsdaten und Geodaten. Momentan existiert jedoch keine geeignete Klassifikation um bestehende und neue Forschungsbeiträge einordnen zu können. In diesem Beitrag werden bestehende Ansätze anhand eines idealtypischen Aufbaus Analytischer Informationssysteme charakterisiert. Nach der Charakterisierung werden durch eine Klassifikation mehrere Varianten für die Integration von Geodaten in Analytische Informationssysteme abgeleitet. Die Unterschie-de der Varianten werden abschließend anhand eines Vergleichsrahmens dargestellt.
