A computational bow-spring model
Bow-springs find few applications in industry. Principally, they are used in archery. In addition, they have found some use in a compression-spring mode in the field of biomechatronics, to emulate elastic human legs. The mechanical behavior (characterized by deflected shape and deformation force) …

Analysis of bow crushing in ship collision
… previous analyses of the collision problem, the bow of the impacting ship was considered rigid. The objective of the present research is to include the finite strength of the bow in the overall collision simulation. The emphasis will be placed on typical raked shapes because some work already has …

The revival and revitalization of musical bow practice
… which stimulated my interest in African musical bows. I grew up in a rural area in the Eastern Cape, historical home of the Xhosa-speaking people, and in which so much Xhosa traditional music has always been actively practiced. It seems hard to believe that musical bow performance never came into …

Bow Articulations in the Late Galant (1775–1812): An Analysis of Bow Strokes in Selected Violin Sonatas of Mozart and Beethoven
… study examines the evolving use of the violin bow during the late<em> galant</em> and Classical era (1776-1812) by means of several violin sonatas by Wolfgang Amadeus Mozart and Ludwig van Beethoven (K. 305, K. 454. Op. 12, No. 1, Op. 96). An analysis of bow articulations supplemented with …

The Makhweyane bow of Swaziland: music, poetics and place
… performers of the Swazi gourd-resonated bow, the makhweyane, create music. Since David Rycroft's study of Swazi bow music in the 1960s and 1970s, little study has been devoted to this musical instrument. The makhweyane is played by a handful of people, each appearing to consider him or …

Simplified Bow Model for a Striking Ship in Collision
… and improve safety. Differences in striking ship bow stiffness, draft, bow height and shape have an important influence on the allocation of absorbed energy between striking and struck ships. The energy absorbed by the striking ship may be significant. The assumption of a "rigid" striking bow may …

Plastic Characterization in Sediment Along the Bow River Near Calgary, Alberta
… contamination in shoreline sediments along the Bow River in Calgary, Alberta, and identified trends in their abundance and distribution. Sediment samples were collected from eight sites along banks of the Bow River. At each site, 1 kg of wet sediment was obtained then filtered, dried, and mixed …

Search for gamma-ray emission from bow shocks of runaway stars
… emission. The study of shock acceleration at bow shocks, created by the supersonic movement of individual stars through the interstellar medium, offers a unique possibility to determine the physical properties of shocks in a less complex environment. The shocked medium is heated by the stellar …

The revival and revitalization of musical bow practice in South Africa
This dissertation is a formal study of musical bow revivals in South Africa, based on an assessment of the instruments' historical and current usage, and functions. This study is also the inevitable result of my responses to certain musical experiences during the past three years, and which …

Geology & Geochemistry of the Kingman Feldspar, Rare Metals and Wagon Bow Pegmatites
In the Mojave Pegmatite district, located in northwestern AZ, numerous pegmatites intrude syn- to post-collisional Paleoproterozoic granitic rocks. The slightly older Cerbat plutons are associated with the suturing of the Mojave and Yavapai terranes whereas Aquarius granites were emplaced during …

Multi-dimensional simulations of bow shocks of massive, high-velocity runaway stars
Stellar bow shocks result from the supersonic collision of stellar winds ejected by runaway stars and the interstellar medium (ISM). Studying their properties provides constraints on mass-loss rates, stellar wind velocities and the properties of the ISM. In this work, we study the formation of bow …
