Simplified recursive P 3 0 model for the fragmentation of polarized quarks

July 2019 · Physical Review D

We revisit the recursive model for the fragmentation of polarized quarks based on the string +P30 mechanism of qq¯ pair creation. We make a different choice for one input function of the model that simplifies the implementation in a Monte Carlo program. No new parameters are introduced, and the relevant results are the same apart from the suppression of the spin-independent correlations between ... [Show full abstract] successive quarks. The advantage of the present version is that it allows us to study analytically the preservation of positivity bounds and it is more suitable for an interface with external event generators like PYTHIA. The theoretical aspects and the simulation results obtained with a stand alone program are discussed in detail and compared with those of the previous version of the model.

A simplified recursive ${}^3P_0$ model for the fragmentation of polarized quarks

March 2019

We revisit our recursive model for the fragmentation of polarized quarks based on the string+${}^3P_0$ mechanism of $q\bar{q}$ pair creation. We make a different choice for one input function of the model that simplifies the implementation in a Monte Carlo program. No new parameters are introduced, and the relevant results are the same apart from the suppression of the spin-independent ... [Show full abstract] correlations between successive quarks. In addition, the present version is more suitable for an interface with external event generators. The theoretical aspects and the simulation results obtained with a stand alone program are discussed in detail and compared with those of the previous version of the model.

EXPERT SYSTEM KNOWLEDGE BASE CREATION AND TUNNING SUPPORT – NPS32 GRAPHICAL ADD-ON

Petr Polach

This paper describes an empty diagnostic expert system that uses graphical interface for creation and modification of its knowledge base. Graphical environment contributes to transparency of the knowledge base structure and the inference processes taking place in it – already during the initial phase of the knowledge base tuning. It also deals with the inner functionality of the expert system and ... [Show full abstract] its other functions – including immediate consultation work-over based on modifications implemented into the knowledge base by the user.

Pianists spend many years practicing on their instrument. As a result they develop alongside their pianistic technique a set of gestural nuances that enable them to perform expressively and establish their own acoustic signature on the piano. This mute layer of nuanced gestures is rarely taken into consideration when developing new keyboard-based gestural interfaces. These often usually require ... [Show full abstract] new gestural vocabularies to be learned resulting in a disruptive experience for the pianist. The main objective of this research is to investigate how new keyboard-based gestural interfaces can enable musicians to control and transform live piano sound through the gestural nuances embedded in their technique. Specifically, how keyboard interfaces with nuanced gestural control can extend the creative possibilities available to classically trained pianists, thus stimulating new approaches to build intuitive interfaces for musical expression, and new ways of learning and playing digital instruments. Towards this goal, interviews, user tests and case studies were conducted with a range of pianists coming from different musical backgrounds, and Reach, an augmented instrument for live sound modulation controlled by gestural nuances embedded in the pianistic technique was developed.

Reach - Designing keyboard instruments with pianists in mind

October 2018

Niccolò Granieri

This poster focuses on the comparative user testing conducted to evaluate Reach, a gesture recognition system for live piano sound modulation. The user testing compares the Reach system with two existing keyboard-based systems for keyboard live sound modulation: ROLI Seaboard (Lamb and Robertson, 2011) and TouchKeys (McPherson, 2012). The study analyses ease of use, learnability and creative ... [Show full abstract] freedom, based on two jazz improvisations each on all three systems by the participants. This is presented along with user experience questionnaire (UEQ) data. The poster illustrates results from the test, focusing on the relationship between the learning curve and creative barrier in digital instruments and showing promising results for touch-free digital musical instruments (DMIs) like Reach. The comparative user testing taken into analysis is part of a larger research project that seeks to investigate how a low degree of invasiveness in digital systems for live sound modulation can reduce the learning curve and eventually make electronic music more accessible.

Reach, a keyboard-based gesture recognition system for live piano sound modulation

June 2019

This paper presents Reach, a keyboard-based gesture recognition system for live piano sound modulation. Reach is a system built using the Leap Motion Orion SDK, Pure Data and a custom C++ OSC mapper1. It provides control over the sound modulation of an acoustic piano using the pianist’s ancillary gestures. The system was developed using an iterative design process, incorporating research findings ... [Show full abstract] from two user studies and several case studies. The results that emerged show the potential of recognising and utilising the pianist’s existing technique when designing keyboard-based DMIs, reducing the requirement to learn additional techniques.
