Violinists often claim that tilting the bow provides greater brilliance. By tilting, the effective width of the bow hair is reduced and the bow force distribution across the bow hair ribbon is changed. Considering that the width of the bow hair of a violin bow is roughly 1/32 of the string length (about 10 mm), and that the relative bow-bridge distance in playing typically varies between 1/8 an...

A skilled string performer is able to play a series of spiccato notes (short strokes played by a bouncing bow) with each onset showing little or no aperiodic motion before a regular slip/stick pattern (Helmholtz motion) is triggered. Kinematic analysis reveals that a well-behaving bow gives nearly vertical impacts on the string, and that the first slip of each note takes place when the normal b...

[1] TheMErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft at Mercury and the Cassini spacecraft at Saturn provide us with orbiters around planets at more diverse heliocentric distances than ever before. The dramatically different solar wind conditions at these two planets should mean that Mercury’s bow shock is considerably weaker (lower Mach numbers) than Satu...

A bow with horse tail hair is used to play the violin. New and worn-out bow hairs were observed by atomic force microscopy. The cuticles of the new bow hair were already damaged by bleach and delipidation, however the worn-out bow hairs were much more damaged and broken off by force, which relates to wearing out.

A micro strip-fed printed bow-tie antenna is presented inorder to achieve wide bandwidth, high gain, and size reduction. A comparisonbetween the bow-tie and the quasi-Yagi (dipole and director)antennas shows that the bow-tie antenna has a wider bandwidth, highergain, lower front-to-back ratio, lower crosspolarization level, andsmaller size. Two-element arrays are designed and their characterist...

The vBow senses the violinist's bow stroke through the encoder of a servo driven by a cable, which is wrapped around a capstan attached to the shaft of the motor, and secured to either end of the virtual bow. The servo engages the bow, simulating friction and vibration of the string on the bow, according to the velocity of the performer's stroke. The result is a musical controller capable of si...

Location and shape of the terrestrial bow shock are analyzed using MAGION 4 (sub satellite of INTERBALL 1) crossings of this boundary and upstream solar wind parameters measured by the WIND spacecraft. Different crossing points were mapped to the Sun Earth line and to the terminator plane using an analytical model of the planetary bow shock previously developed for the Martian bow shock investi...

The bow influences a string performance in two principal ways: ( I ) by adding to the sound quality, primarily set by the violin body, and (2) by serving as the tool through which tones andphrases are formed. The influence on tone quality has been attributed to a modulation of either the relative velocity between bow and string, or the bow pressure, due to the resonances of the bow. New results...

Here we present an antenna-integrated QCL which can be actively and optically modulated using light in the near infrared, creating an optical nanocircuit – coupling two different frequency antennas with a nonlinear active switching element. For our design, we chose two cross-polarized bow-tie antennas with an aligned central spot. We have used detailed FDTD simulations to choose the length of e...

In this paper, we test the hypothesis proposed in a companion paper submitted to this conference (see [SS00]), namely that the playability of a bow stroke can be fully described by three parameters bow velocity, bow position and bow force. Moreover, the envelope of these parameters influences the quality of the attack. In this paper, we present a novel technique for measuring parameters of bowi...
