The present investigations put forth the development of a novel double wall vented rotary fluid heating device. In this device, water is used as process and heated by combustion sugarcane bagasse. proposed method found to provide use more systematic fuel transport system ensure efficient heat transfer fluid. It observed offer many advantages over conventional furnaces obviates any mechanized su...

Drum kits consist of various kinds of percussion instruments. As all percussion instruments are large and heavy, they are inconvenient for drummers to carry and set up. Virtual drums, which include motion sensors and enable drummers to imitate playing drums by stroking a virtual drum, are highly portable. However, drummers, who are used to playing real drums, have difficulty in demonstrating th...

The optical sensors used have their own internal resistance, the extinction of which is leads to fact that sensor gives a certain signal. When beam light hits sensor, resistance decreases. For reliability results obtained, each experiment was carried out in four repetitions. All experiments were under same conditions at constant set rotation speed peg drum.

In the recording of movement by means of a lever on a smoked drum, the use of a frontal writing point offers certain advantages. The lever is normal to the curve of the drum surface and terminates in a small hinge, which is tangential to this curve and supports the actual writing point. The latter usually has two arms projecting below and above the A hinge, the upper one being ibent back at an ...

The paper discusses the features of the Biomass Boiler drum water level. Conventional PID Control System can not reach a satisfaction result in nonlinearity and time different from Biomass Boiler Drum Water Control System. In this study, a kind of fuzzy self-adaptive PID controller is described and this controller is used in biomass boiler’s drum water level control system. Using the simulink t...

In a fully mechanized mining face, there is interference between the hydraulic support face guard and shearer drum. The two collisions seriously affect coal mine production personnel safety. identification of drum can be affected by fog generated when cuts forward. It recovery, not timely block drum, that will also recognition Aiming at above problems, method based on improved YOLOv5s with dark...

The shape of a granular pile in a rotating drum is investigated. Using discrete elements method (DEM) simulations we show that the "S shape" obtained for high rotation speed can be accounted for by the friction on the end plates. A theoretical model which accounts for the effect of the end plates is presented and the equation of the shape of the free surface is derived. The model reveals a dime...

For the purpose of eliminating the troublesome mastoid cavity after tympanoplasty, some surgical procedures have been devised, which consist of preservation of the external ear canal, so that the operative mastoid cavity is primarily closed, with the use of fascia, periost or vein as a tympanic graft. Surgical procedures are as follows : At the first place, mastoidectomy is carried out without ...

This paper aims at presenting our method to generate drum tracks to accompany guitar tracks. Our approach was to work on songs in the Midi format, separate them into several segments and then design our own features for the input guitar tracks as well as for the output drum tracks. We performed clustering algorithms (K-means, mixture of Gaussian, DBSCAN) as well as K-nn to group similar guitar ...

In this paper we present novel rhythm features derived from drum tracks extracted from polyphonic music and evaluate them in a genre classification task. Musical excerpts are analyzed using an optimized, partially fixed Non-Negative Matrix Factorization (NMF) method and beat histogram features are calculated on basis of the resulting activation functions for each one out of three drum tracks ex...
