Phase-Function Normalization in the 3-D Discrete-Ordinates Solution of Radiative Transfer – PART I: Conservation of Scattered Energy and Asymmetry Factor
The conditions for which conversation of scattered energy and phase-function asymmetry factor after discrete-ordinates methods (DOM) directional discretization for 3-D radiative transfer in anisotropic scattering media breaks down are examined. Directional discretization in anisotropic scattering media is found to alter the scattering asymmetry factor—a second-type of ‘‘false scattering.’’ Phase-function normalization which conserves scattered energy alone cannot correct this problem, and conservation of the asymmetry factor is simultaneously required. A normalization technique developed by the authors, which was successfully tested in 2-D asymmetric cylindrical-coordinate radiative transfer analysis, is intensively examined and validated with benchmark problems in 3-D Cartesian coordinates. In Part I of this study, the degree of anisotropy for which normalization is necessary to conserve these inherent quantities is presented for various phase-function approximations and discrete quadrature sets.Peer reviewed
Upon Daedalian Wings of Paper Money: Adam Smith and the Crisis of 1772
Adam Smith advocated laissez faire for most sectors of the economy, but he believed that banking and finance required several forms of regulation including usury laws and the prohibition of small-denomination bank notes. Smith’s support for banking regulation appears to have been a response to the shocks that hit the Scottish banking system during the time that he was composing the Wealth of Nations. The most important was the Crisis of 1772, which has been described as the first modern banking crisis faced by the Bank of England. It resembles the Crisis of 2008 in a number of striking ways. This paper describes the Crisis of 1772, the other shocks that hit the Scottish banking system, and the evolution of Smith’s views on the regulation of banking. It is based on Smith’s writings, the secondary sources, and a quantification of the new issues of Scottish bank notes during Smith’s era.
Phase-Function Normalization in the 3-D Discrete-Ordinates Solution of Radiative Transfer – PART II: Benchmark Comparisons
Radiative transfer in a cubic enclosure, subject to varying conditions, is determined using the discrete-ordinates method (DOM) with the two normalization techniques introduced in Part I of this study. Their predictions are compared with Monte Carlo simulations. For all cases, false scattering due to directional discretization cannot be corrected when the old technique, which solely conserves scattered energy, is implemented; and thus, signifi- cant discrepancies exist when compared to Monte Carlo results. The new technique, which conserves both scattered energy and the asymmetry factor, is able to retain original scatter- ing properties after directional discretization, leading to improved accuracy when compared to Monte Carlo. In addition, a parametric study is presented to gauge the impact of asym- metry-factor conservation on media with various optical properties. Finally, the impact of normalization is investigated for both ultrafast radiative transfer and ballistic incidence with varying incident angle.Peer reviewed
Adam und Eva in der byzantinischen und abendländischen Kunst des Mittelalters
The pictorial art of the Church, as a spiritual product of the Christian civilisation, has continually received great influences from its ecclesiastical tradition and it was defined by its formal aesthetical standards and its iconographic preferences. A more nuanced reading of the parallels can be attained by placing the images in their visual context, which would allow a better appreciation of the meanings within. The biblical story of Adam and Eve, which is the theme of the following thesis, reflects the differentiation between the Eastern and the Western understanding of the events of the history of the holy Oikonomia, a point, which is the major ground for the development of the relative pictorial motifs. The protoplasts are the protagonists from their creation and life in paradise, the fall and expulsion until their resurrection through Christ. Their story is visualised in a number of scenes and episodes, having thus their original sin and resurrection for specific reasons centralised. This doctoral thesis attempts to collect as many parallels of the scenes is possible, trying to collate the Eastern with the Western visual approach in a deductive way, in order to reach our constructive conclusions and make available the combination of the art, theology and liturgy in the scenes of Adam and Eve in Genesis and in Resurrection (Anastasis). The reading we tried to perform was based upon the specific iconographical elements, which were worth to be commented. Our aim was to detect the direct bond between the production of art and the relevant patristic and apocryphal writings or even the theological theories, by quoting texts from the ecclesiastical literature, as well as the liturgical praxis.Die kirchliche Kunst hat als geistiges Produkt der christlichen Kultur stets unter dem Einfluss der kirchlichen Tradition gestanden und wurde durch ihre formalen ästhetischen Standards und ihre ikonographische Auswahl bestimmt. Eine genauere Bestimmung der Parallelen kann erreicht werden, indem man die Bilder in ihren visuellen Kontext stellt, was zu einem besserem Verständnis ihrer Inhalte führt. Die biblische Geschichte von Adam und Eva, welche das Thema unserer Arbeit ist, reflektiert das differenzierte Verständnis der Heilsgeschichte (Oikonomia) in Ost und West, welche die Hauptursache für die Entwicklung der entsprechenden Bildmotive ist. Die Stammeltern sind die Protagonisten dieser Geschichte seit der Schöpfung und dem Leben im Paradies, sowie Sündenfall und Vertreibung, bis zu ihrer Auferweckung durch Christus. Ihre Geschichte wird in einer Reihe von Szenen und Episoden visualisiert, wobei die Ursünde und die Auferstehung aus besonderen Gründen im Mittelpunkt stehen. Diese Dissertation versucht, so viele wie mögliche Gemeinsamkeiten der Darstellung herauszuarbeiten, um so in deduktiver Weise den visuellen Zugang des Ostens und des Westens in Beziehung zu setzen, um zu konstruktiven Ergebnissen zu kommen und eine Verbindung von Kunst, Theologie und Liturgie in den Darstellungen von Adam und Eva in der Genesis und der Anastasis, am Anfang und am Ende also, herzustellen. Unsere Untersuchung basiert auf den spezifischen ikonographischen Elementen, die wir kommentieren. Unser Ziel war es, die unmittelbare Verbindung zwischen der künstlerischen Darstellung und den entsprechenden patristischen oder apokryphen Schriften oder sogar den theologischen Theorien zu ermitteln, indem wir Texte aus der kirchlichen Literatur, aber auch aus der liturgischen Praxis heranzogen. Wir versuchten die Beteiligung der Stammeltern Adam und Eva im Genesis-Zyklus und der Anastasis-Szene in Beziehung zu setzen, deren Darstellungsnormen zur Gänze auf der Heilsverheissung Gottes basieren. So besteht unsere Dissertation aus zwei Teilen: Genesis und Anastasis (Abstieg in den Hades), sowie einem Anhang, welcher die Überschrift „Die Bildsprache der Geschichte der Stammeltern“ trägt, der Bibliographie und einer Liste der verwendeten Abbildungen
Improved treatment of anisotropic scattering in radiation transfer analysis using the finite volume method
Discretization of the integral anisotropic-scattering term in the equation of radiative transfer will result in two kinds of numerical errors: alterations in scattered energy and asymmetry factor. Though quadrature flexibility with large angular directions and further solid-angle splitting in the finite volume method (FVM) allow for reduction/minimization of these errors, computational efficiency is adversely impacted. A phase-function normalization technique to get rid of these errors is simpler and is applied to the three-dimensional (3-D) FVM for the first time to improve anisotropic radiation transfer computation accuracy and efficiency. FVM results are compared to Monte Carlo and discrete-ordinates method predictions of radiative heat transfer in a cubic enclosure housing a highly anisotropic participating medium. It is found that the FVM results generated using the normalization technique conform accurately to the results of the other two methods with little impact on computational efficiency.Peer reviewed
Comparison of Quadrature Schemes in DOM for Anisotropic Scattering Radiative Transfer Analysis
The commonly implemented level-symmetric SN quadrature set for the discrete-ordinates method suffers from a limitation in discrete direction number to avoid physically unrealistic weighting factors. This limitation can have an adverse impact for determining radiative transfer, as directional discretization results in angular false scattering errors due to distortion of the scattering phase function in addition to the ray effect. To combat this limitation, several higher-order quadrature schemes with no directional limitation have been developed. Here, four higher-order quadrature sets (Legendre-equal weight, Legendre-Chebyshev, triangle tessellation, and spherical ring approximation) are implemented for determination of radiative transfer in a 3-D cubic enclosure containing participating media. Heat fluxes obtained at low direction number are compared to the SN quadrature and Monte Carlo predictions to gauge and compare quadrature accuracy. Investigation into the reduction/elimination of angular false scattering with increase in direction number, including heat flux accuracy with respect to Monte Carlo and computational efficiency, is presented. It is found that while the higher-order quadrature sets are able to effectively minimize angular false scattering, the number of directions required is extremely large, and thus it is more computationally efficient to implement proper phase-function normalization to obtain accurate results.Peer reviewed
