Improvisation in Sixteenth-Century Italy: Lessons from Rhetoric and Jazz

Saying that embellishment was a big deal for sixteenth-­century musicians is hardly a bold move; evidence abounds in treatises, music collections, and written accounts from the time. It has also been the subject of a fair amount of keen musicological scholarship over the years. But making sense out of what musicians of the time actually did in performance and trying to reproduce it today has proven to be more difficult, mainly because improvisers, by nature, do not tend to record what they do. The modern prevailing view seems to be that ornamentation was important, mainly because evidence suggests it was so widespread, but ultimately that it was a sort of varnish: something that could add color or texture to the surface of the music but that always left the original clearly discernable underneath. Certainly pieces back then, as today, were performed without embellishments, but perhaps there is more to the ornamentation than mere decorative sheen..

Utilisation de la poussée réversible pour faciliter les atterrissage de quadrirotors sur des surfaces inclinées

Les aéronefs télépilotés à voilure tournante, communément appelés multirotors, sont de plus en plus utilisé pour le loisir, mais aussi dans l'industrie. Leur fiabilité et leur performance ne cessent de s'accroître. Cependant, leur enveloppe d'atterrissage demeure limité. Effectivement, les multirotors commerciaux ne peuvent atterrir que des surfaces horizontales fixes. L'ajout de suspensions et de dispositifs d'adhérence spécialisés est nécessaire pour atterrir sur des surfaces inclinées. Le développement de rotors bidirectionnels, développés initialement pour des multirotors omnidirectionnels, pourrait améliorer l'atterrissage de ces aéronefs. En effet, en utilisant l'inversion de la poussée pour augmenter la force normale et la friction, il serait possible d'augmenter l'inclinaison maximale permettant un atterrissage sécuritaire et de diminuer l'espace requis pour l'atterrissage. Le projet de recherche présenté dans ce mémoire a pour but de quantifier les avantages de la poussée réversible ainsi que d'identifier les limites des bénéfices. Ce mémoire présente un modèle conçu pour simuler la dynamique d'un quadrirotor sujet aux contacts intermittents entre son train d'atterrissage et la surface, ainsi que la dynamique du rotor. Le modèle a été validé en effectuant des essais expérimentaux sur des surfaces à faible et à haute friction, et en utilisant des algorithmes génétiques pour identifier certains paramètres du modèle. À l'aide du modèle, plusieurs algorithmes simples d'atterrissage ont été simulés et puis testés expérimentalement. L'utilisation d'une impulsion angulaire à l'aide de la poussée différentielle afin d'éliminer la vitesse angulaire du quadrirotor après l'impact a aussi été étudiée. Finalement, les simulations et les essais démontrent que la poussée réversible peut presque doubler l'inclinaison maximale sur laquelle un quadrirotor peut atterrir ainsi que la vitesse verticale d'approche, tout en diminuant la distance et la durée requise pour l'atterrissage

Polyenamines from aromatic diacetylenic diketones and diamines

The synthesis and characterization of several polyenamine ketones are discussed wherein conjugated diacetylenic diketones and aromatic diamines are used as a route to the formation of high molecular weight polyenamine ketones which exhibit good mechanical properties and can be cast into creasible films. Typical polymerization conditions involved the reaction of stoichiometric amounts of 1,4- or 1,3-PPPO and a diamine at 60 to 130 C in m-cresol at (w/w) solids content of 8 to 26% for a specified period of time under a nitrogen atmosphere. Novel polyenamine ketones were prepared with inherent viscosities as high as 1.99 dl/g and tough, clear amber films with tensile strengths of 12,400 psi and tensile moduli of 397,000 psi were cast from solutions of the polymers in chloroform. In most cases, the elemental analyses for the polyenamine ketones agree within + or - 0.3% of the theoretical values

White Supremacy and the Major Scale: Reframing Narratives to Teach the Blues, Improvise, and Check In with Students

Increasing diversity and equity in secondary and college music programs is a common thread in the scholarship across disciplines in the field. While crucial work is being done to decolonize curricula broadly, students often express difficulty relating to formal music study and teachers struggle to balance desires to diversify repertoire and incorporate alternative pedagogical strategies with their own training. Narratives of white supremacy and music have intersected for over 400 years, but the effect goes beyond the composers and pieces we choose to program or teach. It influences foundational concepts of theory, tuning, and even what notes are (the major scale). This paper uses historical and pedagogical research methods to examine the connections between narratives of white supremacy and formal music study, and then shows how the practice of reframing these narratives can lead to a reframing of classroom and applied teaching strategies. Specific attention is given to teaching the blues and improvisation, but the concepts can be applied to different teaching situations as well. The goal is to offer suggestions to aid in the process of creating classroom settings that are more accessible and applicable to students and less daunting for educators

Archaeology of Atafu, Tokelau: Some initial results from 2008

Surface survey, shovel testing, and stratigraphic excavations were done on Atafu Atoll in Tokelau during August 2008. Initial results suggest that Fale Islet has the most potential for further archaeological research. Dense cultural deposits on this islet are >1 m (39 in.) deep. Cultural material recovered includes food bone, fire-affected volcanic rock, tool-grade basalt flakes and tool fragments, Tridacna shell adzes, and pearl-shell fishhook fragments. Dog bone occurs from the earliest deposits through to the late prehistoric, while pig bone is found only in historic contexts. Fish bone is common throughout, and, with the exception of Tridacna, there are few edible mollusk remains. Initial EDXRF (Energy Dispersive X-Ray Fluorescence) analyses have found the basalt to be consistent with documented sources on Tutuila, Samoa. Basal radiocarbon dates from two excavation units are 660-540 cal. BP and 500-310 cal. BP (at 2σ)
