In automatic music transcription, metadata extraction from recorded audio data or speaker separation in video conferencing, it is a significant prerequisite task to analyze and separate the audio signal into their original source components. In this report, I study and analyze a set of methods of the extraction of percussive instruments metadata from polyphonic music. It mainly focuses on the s...

To address the problems of high breakage rates, entrainment losses and many unthreshed kernels when harvesting moisture content maize seeds, a seed threshing test was designed based on multifunctional harvester stand by this group.In order to determine optimum operating parameters unit, single-factor experiments orthogonal tests were carried out using drum speed, concave plate clearance feed ra...

The boiler drum level control unit is one of the main parameter in the thermal power station. Currently the boiler drum parameters are monitored only by using MATLAB software. There is no automatic control available. In the proposed system the boiler drum parameters such as temperature level, pressure level, water level and Droplet identifier are measured and controlled by using embedded proces...

We discuss in this paper two post-processings for drum transcription systems, which aim to model typical properties of drum sequences. Both methods operate on a symbolic representation of the sequence, which is obtained by quantizing the onsets of drum strokes on an optimal tatum grid, and by fusing the posterior probabilities produced by the drum transcription system. The first proposed method...

This paper presents an evaluation and comparison of four input devices for percussion tasks: a standard tom drum, Roland V-Drum, and two established examples of gestural controllers: the Buchla Lightning II, and the Radio Baton. The primary goal of this study was to determine how players’ actions changed when moving from an acoustic instrument like the tom drum, to a gestural controller like th...

While adult green dock leaf beetles Gastrophysa viridula use tarsal adhesive setae to attach to and walk on smooth vertical surfaces and ceilings, larvae apply different devices for similar purposes: pretarsal adhesive pads on thoracic legs and a retractable pygopod at the 10th abdominal segment. Both are soft smooth structures and capable of wet adhesion. We studied attachment ability of diffe...

The potential of numerical methods for the solution and optimization of industrial granular flows problems is widely accepted by the industries of this field, the challenge being to promote effectively their industrial practice. In this paper, we attempt to make an exploratory step in this regard by using a numerical model based on continuous mechanics and on the so-called Particle Finite Eleme...

A peanut harvest separation and conveying device was designed considering the shortage of machinery poor harvesting effect in China. The interaction between mechanism pod-soil mixture analysed to obtain motion state relative conveyor. ADAMS simulation applied spatial curve trajectory process. study determined that optimum operating parameters conveyor were a drum speed 280 r/min an inclination ...
