R.M. Simmons presentation, Rena Smart book review
No full textR.M. Simmons of the Gospel Music Workshop of America gives a presentation on the African influence in the African American religious experience. He explains how African slaves brought to America their concept of music (utilitarian concept of music). Simmons further discusses the fusion between the utilitarian concept and the Western concept of religion resulting in spirituals. He also describes hymn categories in early forms of formal African American worship experiences. Simmons takes questions from the audience among which is Dr. Riggins Earl Jr. Video concludes with a book review on Christian Theology and Ethics by Rena Smart.The Atlanta University Center Robert W. Woodruff Library acknowledges the generous support of the National Endowment for Humanities - Humanities Collections and Reference Resources Implementation Project Grant in supporting the processing and digitization of a number of its major archival collections as part of the project: Spreading the Word: Expanding Access to African American Religious Archival Collections at the Atlanta University Center Robert W.

Velocity-Gradient Probability Distribution Functions in a Lagrangian Model of Turbulence
No full textThe Recent Fluid Deformation Closure (RFDC) model of lagrangian turbulence is recast in path-integral language within the framework of the Martin-Siggia-Rose functional formalism. In order to derive analytical expressions for the velocity-gradient probability distribution functions (vgPDFs), we carry out noise renormalization in the low-frequency regime and find approximate extrema for the Martin-Siggia-Rose effective action. We verify, with the help of Monte Carlo simulations, that the vgPDFs so obtained yield a close description of the single-point statistical features implied by the original RFDC stochastic differential equations

Colonising "The Coral Island": A Postcolonial Reading of R.M. Ballantyne's Children's "Classic"
No full textstudent essayBeing written during the rise of the British Empire in the 1850sm R.M. Ballantyne's boys' adventure story "The Coral Island" is in many ways a product of its time, conveying imperial ideas and Victorian values to the young reader. Through his portrayal of the native inhabitants in relation to his descriptions of the three British protagonists, the author creates a stereotyped image of the natives as primitive savages. Due to the further use of a first person narrator and realist pretensions, the dated racist ideas become influential upon the reader. In spite of the fact that the novel has been considered as an entertaining children's classic by generations since its first publication, "The Coral Island" should not be classified as good children's literature today but should rather be historicised as a result of its controversial contents. By adopting a postcolonial approach and applying postcolonial theory in my analysis of R.M. Ballantyne's "The Coral Island", I have in this essay endeavoured to demonstrate in what ways the novel would prove problematic as a children's book today. In my first chapter I present the imperial ideas and Victorian values that are conveyed, whereas in my second chapter I discuss Ballantyne's stereotyping of the natives. As a result of my study of this novel, I have exemplified how the author portrays the three British boys as representative of the Victorian ideals of the time. I have also illustrated their assumed superiority over nature and their roles as colonisers. Furthermore, my analysis of "The Coral Island" has revealed how Ballantyne communicates both white superiority as well as the Western "oblibation" to civilise primitive people throug Christian conversion. Consequently, the novel promotes the ideology of its time. As a result of my findings, I would like to argue that "The Coral Island" should today be viewed as a text conveying historical ideas and values rather than as an exciting children's classic
Acoustic emmission gedrag van verschillende grondsoorten
No full textDit rapport vat de resultaten samen van de meetrapporten "Acoustic Emission" (A.E.) gedrag van verschillende grondsoorten door ing. F.M. Schenkeveld, LGM en "Acoustic emission laboratory testing of sand, clay and peat soils" door Prof. R.M. Koerner, Drexel University, U.S.A. Het onderzoek werd verricht in opdracht van het Centrum voor Onderzoek Waterkeringen (COW), in samenwerking met het Laboratorium voor Grondmechanica (LGM). Projectleider voor het COW was ir. A. Penning. Het doel van het onderzoek is de evaluatie van de "acoustic emission"-methode met betrekking tot stabiliteitsproblemen bij Nederlandse dijken. Tijdens het vooronderzoek is kontakt gelegd met Prof. R.M. Koerner (R.M.K.), Drexel University, U.S.A. Om een goede basis te geven aan het onderzoek werd met Prof. Koerner een gezamenlijk project uitgevoerd. "Acoustic Emissions" zijn spanningsgolven die gegenereerd worden in een materiaal onder spanning tijdens deformatie. Soms zijn deze spanningsgolven hoorbaar (kraken van hout), maar vaak niet vanwege de lage amplitude en hoge frequentie. Een piezoelectrische sensor wordt gebruikt om de "acoustic emissions" te detecteren. De opnemer produceert een electrisch signaal evenredig met de amplitude van de waargenomen trilling. Het signaal wordt dan versterkt, gefilterd en geteld of op een andere wijze gekwantificeerd. Achtergrondruis en andere ongewenste verstoringen worden gefilterd of apart gekwantificeerd en afgetrokken van de resultaten. De tellingen of andere bewerkte resultaten van de emissies worden dan gecorreleerd met het materiaal gedrag om empirisch de veiligheid van de onderzochte situatie te bepalen. Indien er geen acoustic emissions zijn is het materiaal in het algemeen in rust en stabiel. Evenwel als er emissies worden waargenomen is het materiaal in beweging, hetgeen uiteindelijk kan leiden tot bezwijken. De komponenten van het huidige "acoustic emission" systeem bestaan uit: een stalen staaf (om het signaal vanuit de grond naar een geschikt waarnemingspunt te brenger.) , een sensor (geofoon, versnellingsopnemer,hydrofoon of een andere opnemer die een mechanische trilling in een electrisch signaal omzet), een voorversterker (om het signaal te versterken indien een lange kabel wordt gebruikt), filters (om ongewenste gedeelten van het signaal te elimineren), een versterker (om het signaal verder te versterken voor signaalbewerking) en een signaalbewerkingssysteem. Het signaalbewerkingssysteem is over het algemeen een teller die telt als een bepaalde drempelwaarde wordt overschreden.TAW/EN
