A TIME AND MOTION STUDY OF THE ANAESTHETIST'S INTRAOPERATIVE TIME

British Journal of Anaesthesia, 1988
A time and motion study was made of anaesthetists during 32 surgical procedures. Thirteen activities performed by the anaesthetist were defined for the study. Time and event data were recorded electronically and analysed by digital computer. Activity and link analysis techniques were used to analyse the data.

Characterizing Movement Fluency in Musical Performance: Toward a Generic Measure for Technology Enhanced Learning

Frontiers in Psychology, 2019
Virtuosity in music performance is often associated with fast, precise, and efficient sound-producing movements. The generation of such highly skilled movements involves complex joint and muscle control by the central nervous system, and depends on the ...

Deterministic Brownian motion generated from differential delay equations

, 2011
This paper addresses the question of how Brownian-like motion can arise from the solution of a deterministic differential delay equation. To study this we analytically study the bifurcation properties of an apparently simple differential delay equation ...

Emphatic Articulation: ‘Klangrede’ as a performative concept in Nikolaus Harnoncourt’s orchestral interpretation

Studia Musicologica Norvegica
In a 2004 interpretation of Schubert’s Symphony in B minor, Austrian conductor Nikolaus Harnoncourt and the Berlin Philharmonic foreground a certain awareness regarding articulation.

Vortex and translational currents due to broken time-space symmetries

, 2008
We consider the classical dynamics of a particle in a $d=2,3$-dimensional space-periodic potential under the influence of time-periodic external fields with zero mean.

New features of some proton-neutron collective states

, 2005
Using a schematic solvable many-body Hamiltonian, one studies a new type of proton-neutron excitations within a time dependent variational approach. Classical equations of motion are linearized and subsequently solved analytically.

Inverse and indirect mappings in embodied AI systems in everyday environments

Frontiers in Computer Science
This paper explores how musicking technologies—interactive systems with musical properties—can enhance everyday public environments. We are particularly interested in investigating the effects of musical interactions in non-musical settings, such as ...

Space-time velocity correlation function for random walks

, 2013
Space-time correlation functions constitute a useful instrument from the research toolkit of continuous-media and many-body physics. We adopt here this concept for single-particle random walks and demonstrate that the corresponding space-time velocity ...

Togetherness in musical interaction [version 1; peer review: 2 approved, 3 approved with reservations]

Routledge Open Research
Playing music as part of a group is challenging, but also rewarding. What factors come together to maximize rewarding group playing experiences? How do feelings of enjoyment, frustration, and social (dis)connection shape group performance as it unfolds ...

Quantization and Fractional Quantization of Currents in Periodically Driven Stochastic Systems I: Average Currents

, 2012
This article studies Markovian stochastic motion of a particle on a graph with finite number of nodes and periodically time-dependent transition rates that satisfy the detailed balance condition at any time.
