This paper presents the results of a recent study of common violin bowing techniques using a newly designed measurement system. This measurement system comprises force, inertial, and position sensors installed on a carbon fiber violin bow and electric violin, and enables recording of real player bowing gesture under normal playing conditions. Using this system, performances of six different com...

Implant alignment is an important factor affecting clinical results associated with total knee arthroplasty (TKA). No report exists showing the utility of an accelerometer-based portable navigation system among patients with marked femoral bowing. The aim of this study was to evaluate the accuracy of a portable navigation system for implant alignment in Asian patients with marked femoral bowing...

The authors report on midinfrared photoreflectance measurements of the band gap E0 and spin-orbit splitting energies 0 in InAs-rich InAsSb and GaInAsPSb samples for varying antimony contents 22.5%. The E0 behavior as a function of Sb content is consistent with the literature value bowing parameter of 670 meV. However, 0 does not exhibit the positive bowing of +1170 meV quoted in the literature:...

A bowing is a sequence of bow motions that enable a piece of music to be played on a string instrument with an appropriate interpretation and sound. Traditional notation shows only the bow direction for a few notes. We propose a bowing model, which contains information about the bowings of all the notes, and we show how the bowing model can be represented in software and describe how algorithms...

We describe the ongoing development of a system to support the teaching of good posture and bowing technique to novice violin players. Using an inertial motion capture system we can track in real-time a player’s bowing action and how it deviates from a target trajectory set by their music teacher. The system provides real-time vibrotactile feedback on the correctness of the student’s posture an...

Introduction Traumatic bowing is a commonly missed diagnosis on which only little information is available, inadequate treatment can cause permanent function loss. Method A systematic review would determine what the effect is of treatment of traumatic bowing of the lower arm in children on the functional outcome. A search on Embase, Medline, Web of Science, Scopus, Cochrane, Pubmed publisher,...

Cello bowing techniques are classified by applying supervised machine learning methods to sensor data from two inertial sensors called the Orient specks – one worn on the playing wrist and the other attached to the frog of the bow. Twelve different bowing techniques were considered, including variants on a single string and across multiple strings. Results are presented for the classification o...

Purpose The objective was to evaluate the relationship between side-to-side differences of lateral femoral bowing and varus knee deformity based on two-dimensional (2D) assessment in unilateral total knee arthroplasty (TKA). Materials and Methods A total of 143 patients with varus knee osteoarthritis who underwent unilateral TKA were enrolled. We evaluated the side-to-side differences of the ...

This thesis addresses sound production in bowed-string instruments from two perspectives: the physics of the bowed string, and bow control in performance. Violin performance is characterized by an intimate connection between the player and the instrument, allowing for a continuous control of the sound via the main bowing parameters (bow velocity, bow force and bowbridge distance), but imposing ...

congenital dislocation of the knee (cdk) is a rare disorder. we report the case of a 7-year-old girl with bilateral knee stiffness, marked anterior bowing of both legs, and inability to walk without aid. radiologic investigation revealed bilateral knee joint dislocation accompanied by severe anterior bowing of both tibia proximally and posterior bowing of both femur distally, demonstrating a co...
