Abstract Stepped spillways are suitable and economical options for high-storage dams that require significant energy dissipation, structural adaptation to roller-compacted concrete dams, spontaneous flow aeration. In this study, a numerical analysis of the hydraulic characteristics skimming regime stepped spillway Zirdan Dam is carried out. A comparison between smooth provided. By preparing mod...

Skilled pianists were requested to interactively adjust note (i.e., key depression) durations in simple sequences, played under computer control on a digital piano, so as to sound optimally staccato (perception task) and to perform analogous sequences with staccato articulation on the same instrument as well as on a real piano (production task). The independent variables were tempo, register, a...

Independent control of finger movements characterizes skilled motor behaviors such as tool use and musical performance. The purpose of the present study was to identify the effect of movement frequency (tempo) on individuated finger movements in piano playing. Joint motion at the digits was recorded while 5 expert pianists were playing 30 excerpts from musical pieces with different fingering an...

This study investigated the perception and production of legato ("connected") articulation in repeatedly ascending and descending tone sequences on a digital piano (Roland RD-250s). Initial measurements of the synthetic tones revealed substantial decay times following key release. High tones decayed faster than low tones, as they did prior to key release, and long tones decayed sooner than shor...

A series of Ru(II) arene complexes of mono- and bidentate N-donor ligands with carboxyl or ester groups and chlorido ancillary ligands were synthesised and structurally characterised. The complexes have a distorted tetrahedral piano-stool geometry. The binding interaction was studied with calf thymus DNA (CT-DNA) by absorption titration, viscosity measurement, thermal melting, circular dichrois...

Turbulences in liquids caused by jets can be of interest for numerous applications. For one, it concerns flood spillway structures within civil engineering but also is key in any area where turbulent mixing is present. The numerical simulations of jets that impinge into plunge pools are still in an early phase of their development. This paper verifies the accuracy of the Flow-3D software packag...

Abstract Algal bloom has been a persistent problem for both fresh and marine water, with no exception coastal reservoir (CR). Among the algal mitigations CR, shape optimisation to reduce occurrence frequently mentioned. However, there was literature found on actual study or process CR. Thus, this research done bridge gap, particularly second-generation Hydrodynamic model of MIKE 21 used, second...

A system is presented for detecting common gestures, musical intentions and emotions of pianists in real-time using kinesthetic data retrieved by wireless motion sensors. The algorithm can detect six performer intended emotions such as cheerful, mournful, and vigorous, completely and solely based on low-sample-rate motion sensor data. The algorithm can be trained in real-time or can work based ...

Mixture Hierarchical Model Instead of assuming that vt is normally distributed, assume that vt comes from a mixture of normal distributions Intuition: Suppose for “genre tags” clusters around 0.25 and for “acoustic tags” clusters around 0.05 then if = 0.20, then vt might have two peaks at 0.05 and -0.15. 10,870 songs 2 tag vocabularies 71 genre and subgenre tags (e.g., “rock”, “delta blues”, “t...
