In musical performances with expressive tempo modulation, the tempo variation can be modelled as a sequence of tempo arcs. Previous authors have used this idea to estimate series of piecewise arc segments from data. In this paper we describe a probabilistic model for a time-series process of this nature, and use this to perform inference of singleand multi-level arc processes from data. We desc...

In computational musicology research, clustering is a common approach to the analysis of expression. Our research uses mathematical model selection criteria to evaluate the performance of clustered and non-clustered models applied to intra-phrase tempo variations in classical piano performances. By engaging different standardisation methods for the tempo variations and engaging different types ...

PS-TEMPO, a polymer-supported 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) was successfully applied as a recyclable, active and selective catalyst for the oxidation of alcohols. Bleach, molecular oxygen and air were successfully used as terminal oxidant under conditions suitable for industrial applications. The intrinsic activity and selectivity of TEMPO for primary alcohols to aldehydes were r...

The mechanistic pathway of TEMPO/I₂-mediated oxidative cyclization of N,N-diaryl amino alcohols 1 was investigated. Based on direct empirical experiments, three key intermediates (aminium radical cation 3, α-aminoalkyl radical 4, and iminium 5), four types of reactive species (radical TEMPO, cationic TEMPO, TEMPO-I, and iodo radical), and three types of pathways ((1) SET/PCET mechanism; (2) HAT...

We provide an overview of two algorithms submitted for the Audio Tempo Extraction contest within MIREX 2005: A non-causal Matlab implementation (Davies submission) [4] and a real-time C implementation (Brossier submission) [3]. Both algorithms extract a primary and secondary tempo, associated phase values for each tempo and the relative salience of the slowest tempo. Results indicate that in co...

Surface partitioning of 2,2,6,6-tetramethyl-1-piperidynyloxy radical (Tempo) to the air/water interface follows a Langmuir isotherm. The partition constant was obtained by the surface tension measurements in the concentration range of 1.0 x 10(-4)-2.4 x 10(-3) M yielding K = 640 +/- 99 M(-1). The lateral mobility of Tempo at the air/water interface was measured electrochemically in the surface ...

This article provides insights into aspects of tempo and rhythmic elaboration in Hindustani music, based on a study of a large corpus of recorded performances. Typical tempo developments and stress patterns within a metrical cycle are computed, which we refer to as tempo and rhythm patterns, respectively. Rhythm patterns are obtained by aggregating spectral features over metrical cycles. They r...

We live in our own rhythms in daily lives. Human life is closely related to rhythm as the words “talk rhythm,” “getting into the rhythm” and the “Biorhythm” show. The rhythm is important for us to live in order and cheerfully. Each person has his/her own action rhythm called the “Personal Tempo.” It is the basic rhythm observed in person's voluntary actions, such as tapping on a table. Psycholo...

Although the sequence of pubertal maturation remains consistent across most individuals, the timing and tempo of development fluctuate widely. While past research has largely focused on the sequelae of pubertal timing, a faster tempo of maturation might also present special challenges to children for acclimating to new biological and social milestones. Using latent growth curve modeling, the pr...

This extended abstract details a submission to the Music Information Retrieval Evaluation eXchange in the Audio Beat tracking task. The basic idea is based on the algorithm which submitted by Daniel P.W. Ellis in MIREX 2006. We consider about the energy of beats in order to approximate the human auditory system and improve tracking accuracy. I. BEAT TRACKING WITH A MOVING WINDOW In MIREX 2009, ...
