One of the main bottlenecks in the progress of the Music Information Retrieval (MIR) research field is the limited access to common, large and annotated audio databases that could serve for technology development and/or evaluation. The aim of this paper is to present in detail the ENST-Drums database, emphasizing on both the content and the recording process. This audiovisual database of drum p...

Design issues in developing an interactive performance system are discussed. The development of Drum-Boy, an interactive percussion system for non-experts, is documented, along with discussions of features that make such a real-time creative environment effective. Concrete examples of problems encountered during the design and development phase of Drum-Boy are investigated. Specific issues incl...

since threshing is one of the most sensitive rice post-harvest processing operations, this study was conducted to evaluate the threshing performance in axial - flow paddy thresher. independent variables consisted of: drum speed at five levels (550, 650, 750 and 850 rpm), equivalent to peripheral velocities of: 14.67, 17.35, 20.01 and 22.37 m/s, respectively, paddy moisture content at two levels...

a prototype of a straw chopper, equipped with a discharge system was designed and fabricated in the department of mechanics of agricultural machinery, university of tehran, karaj, iran. to test for the effective performance of the machine, the effects of such parameters as: drum speed (at three levels of: 400, 540, and 800 rpm), screen size (at two levels: 2.5 and 4 cm), and number of blades on...

In this study, a new type of rotary dryer filled with inert alumina ceramic bead (ACB) fillers was introduced to treat the industrial wastewater, e.g., high-salt wastewater and landfill leachate. Numerical simulations based on Discrete Element Method (DEM) motion trajectory ACB in were conducted, parameters flight structure, rotational speed, filling degree dynamic behavior optimized. Under var...

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...

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...
