3-DIMENSIONAL FINITE-ELEMENT ANALYSIS WITH PHASE-CHANGE BY TEMPERATURE RECOVERY METHOD
No full textFinite element analyses for three dimensional problems in solidification have been made. For handling the release of latent heat of solidification, the temperature recovery method was applied. In analyses, the accuracy of the computed results depended upon the element size and the time increment used in simulations. An interface heat transfer coefficient between the mold and the casting was determined numerically as a function of time and used in calculations. The predicted temperatures were in good agreement with the available solutions in the literature.The authors would like to hank Profs S. Kobayashi and T. Altan for their continuous

A Rosary of Rubies: The Chronicle of the Gur-rigs mDo-chen Tradition from South-Western Tibet
Full text linkThe mDo-chen bKa’-brgyud-pa school represents a little known Buddhist tradition from Mang-yul Gung-thang in south-western Tibet. It goes back to a Buddhist yogin known as Ma-bdun-pa or Ma-bdun ras-chen (12th/13th c.) and was later mainly spread by members of the Gur family. Although belonging to the “Upper ’Brug” (stod ’brug) branch of the ’Brug-pa bKa’-brgyud-pa school, the mDo-chen tradition has always been deeply infused with the “spoken teachings” (bka’ ma) and “treasure teachings” (gter ma) of the rNying-ma-pa school, and the cult of the “Seven Ma-mo Sisters” (ma mo mched bdun) was particularly practised and transmitted by its members. This book presents a critical edition, an annotated translation and a photographic reproduction of a manuscript copy of a rare chronicle of the Gur-rigs mDo-chen tradition written by Brag-dkar rta-so sPrul-sku Chos-kyi dbang-phyug (1775–1837). The text provides us with an overview of the tradition’s development mainly through biographical accounts but also through prophecies, prayers and praises for individual masters. The study concludes with two appendices based on the mDo chen bka’ brgyud gser ’phreng, a lineage history composed in the 15th century, and the “records of teachings received” (thob yig) of three important members of the Gur family, thus allowing us to gain an insight into the transmissions of the mDo-chen bKa’-brgyud-pa school and the interactions of its representatives with other important Buddhist teachers up to the 18th century. The present work is a further outcome of the author’s investigations into the cultural and religious traditions of south-western Tibet and the neighbouring Himalayan valleys
Toward a Motivation Model of Pragmatics/ Rong Chen.
No full textIn English.With the "discursive turn" has come a distrust - a complete rejection by some - of theories that seek deeper reasons for surface phenomena. Rong Chen argues that this distrust, with its accompanying overemphasis on specificity and fluidity of linguistic meaning and social values, is unwarranted and unhelpful. Drawing on insights from social theories and various strands of pragmatics, he proposes a motivation model of pragmatics (MMP), contending that language use can be adequately, coherently, and elegantly studied via the motivation behind it in its varied and dynamic contexts. The model, with its well-laid out components, is then applied to (im)politeness research, cross-cultural pragmatics, diachronic pragmatics, discourse and genre analysis, conversation analysis, identity construction, and the study of metaphor, sarcasm, parody, and lying. MMP is thus a framework aimed at accounting for fluidity with stable notions, specificity with general principles, and differences with similar underlying factors. As such, the book should appeal to students of pragmatics, (im)politeness, conversation analysis, sociolinguistics, applied linguistics, communication, sociology, and psychology.Frontmatter -- Foreword -- Contents -- List of figures -- List of tables -- Chapter 1 Pragmatics then and now -- Chapter 2 A motivation model of pragmatics (MMP) -- Chapter 3 MMP and (im)politeness -- Chapter 4 MMP and cross-/intercultural variation -- Chapter 5 MMP and diachronic pragmatics -- Chapter 6 MMP and discourse -- Chapter 7 MMP and metaphor -- Chapter 8 MMP and the non-literal -- Afterword -- References -- Appendix -- Subject index -- Author index1 online resource (XIII, 333 p.)
FINITE-ELEMENT SIMULATION OF SOLIDIFICATION WITH MOMENTUM, HEAT AND SPECIES TRANSPORT
No full textIt is well known that fluid flow phenomena in the solidifying zone play a major role in forming macrosegregation and microstructure. In order to understand the interaction of fluid flow in a solidifying medium, unsteady state natural convection both in the liquid pool and in the interdendritic region and solute redistribution due to this natural convection together with changes in the morphology due to fluid flow such as shearing off of the dendrites should be solved simultaneously. Recently, some progress has been made in solving solidification problems considering fluid flow in solidifying ahoy systems. In order to handle fluid flow the interdendritic flow was treated by assuming a Darcy's flow introducing permeability as a function of liquid volume fraction. In this paper, a two-dimensional finite element program was developed for solving the temperature, velocity, and composition distributions simultaneously using the temperature recovery method. Several numerical examples demonstrate the capability and usage of the developed finite element program.The authors wish to thank Prof. S. Kobayashi

Zur "Topographie chrétienne" von Kaiseraugst (AG) im 4. bis 9. Jahrhundert
Full text linkFür 343/344 resp. 346 n. Chr. ist mit Justinianus ein episcopus Rauricorum bezeugt. Etwa gleichzeitig wird im Castrum Rauracense (Kaiseraugst/AG) eine Saalkirche mit Annexbauten errichtet. Ab der 2. Hälfte des 4. Jahrhunderts lässt sich christliches Gedankengut in Form von Kleinfunden und Grabbauten sowie anhand der Beigabensitte nachweisen. Eine Grabkirche. Inschriften und weitere Steindenkmäler bezeugen, dass das Castrum Rauracense bis in das 7. Jahrhundert hinein ein wichtiges christliches Zentrum blieb. Die Bezeichnung von Ragnacharius als praesul Augustanae et Basiliae ecclesiae (um 618) dürfte folglich lediglich eine Absicht widerspiegeln. Konkret fassbar wird die wohl im Laufe des 8. Jahrhunderts vollzogene Verlegung des Bischofssitzes nach Basilia (Basel) nämlich erst mit dem zwischen 805 und 823 errichteten Haito-Münster. An episcopus Rauricorum named Justinianus is attested in 343/344 resp. 346 A.D. At about the same time in Castrum Rauracense (Kaiseraugst/AG) a church was constructed with annexed buildings. From the second half of the 4th century, evidence of Christianity is found in the form of small finds, tombs and grave goods. A funereal church, inscriptions and other stone monuments testify to the importance of the Castrum Rauracense as a centre of Christianity until well into the 7th century. It is therefore likely that the designation of Ragnacharius as praesul Augustanae et Basiliae ecclesiae reflected one specific purposethe transfer of the bishop's seat to Basilia (Basel) in the course of the 8th century. This probably occurred only after the completion of the Haito Münster, built between 805 and 823
