The dynamics of double-diffusive gravity currents exhibiting the fingering instability were examined using 2D and 3D simulations of a lock exchange initial configuration. It was found that although the spreading of the currents was governed by a balance of buoyancy and turbulent drag forces, currents with more intense fingering spread faster than those with less intense or no fingering. This wa...

Piano players need to learn various techniques such as correct keying and fingering. However, the lighted keyboards, which light up the key and are the most commonly used piano learning supports, have several problems for learners, such as difficulty in understanding the presented fingering information and flow of keying positions, and lack of a fingering check function. To resolve these proble...

This paper describes a method that estimates the appropriate violin fingering pattern according to the player’s skill level. A violin can produce the same pitch for different fingering patterns, which generally vary depending on skill level. Our proposed method translates musical scores into suitable fingering patterns for the desired skill level by modeling a violin player’s left hand based on...

This work presents an automated violin fingering estimation method that facilitates a student violinist acquire the “sound” of his/her favorite recording artist created by the artist’s unique fingering. Our method realizes this by analyzing an audio recording played by the artist, and recuperating the most playable fingering that recreates the aural characteristics of the recording. Recovering ...

This paper discusses a piano fingering model for both hands and its applications. One of our motivations behind the study is automating piano reduction from ensemble scores. For this, quantifying the difficulty of piano performance is important where a fingering model of both hands should be relevant. Such a fingering model is proposed that is based on merged-output hidden Markov model and can ...

The shape of an electronic droplet in the quantum Hall effect is sensitive to gradients of the magnetic field, even if they are placed outside the droplet. Magnetic impurities cause a fingering instability of the edge of the droplet, similar to the Saffman-Taylor fingering instability of an interface between two immiscible phases. We discuss the fingering instability and some algebraic aspects ...

This paper presents a computational model of fingering for string instruments, based on a graph search approach. The implemented fingering model, which accounts for the bio-mechanical constraints of the performer’s hand, is interfaced with a physical model of the classical guitar, which exploits the fingering to compute some sound synthesis parameters. The output of the system is validated agai...

This article presents a method to visually detect and recognize fingering gestures of the left hand of a guitarist. This method has been developed following preliminary manual and automated analysis of video recordings. These first analyses led to some important findings about the design methodology of a vision system for guitarist fingering, namely the focus on the effective gesture, the consi...

We propose a new watermarking method that hides the writer’s identity into symbolic musical scores featuring fingering annotations. These annotations constitute a valuable part of the symbolic representation, yet they can be slightly modified without altering the quality of the musical information. The method applies a controlled distortion of the existing fingerings so that unauthorized copies...

This article presents a method to visually detect and recognize fingering gestures of the left hand of a guitarist. The choice of computer vision to perform that task is motivated by the absence of a satisfying method for realtime guitarist fingering detection. The development of this computer vision method follows preliminary manual and automated analyses of video recordings of a guitarist. Th...
