Abstract The technique and technology of movement displacement the powder product inside drum dryer with a paddle agitator have been developed. Theoretical studies were carried out to assess effect system forces on rotating when in opposite direction is exposed it, which allowed estimating throughput capability drying unit. It established that, an increase speed mixing product, increases. resul...

The voice is a rich and powerful means of expressing acoustic concepts such as musical sounds. Recent research on vocal imitations has demonstrated the viability of using the voice to search for sounds, using query by vocalisation. Here we present the methods used to develop a dataset for evaluating the performance of query by vocalisation systems for drum sounds. The dataset consists of imitat...

The analysis and separation of audio signals into their original components is an important prerequisite to automatic transcription of music, extraction of metadata from audio data, and speaker separation in video conferencing. In this paper, a method for the separation of drum tracks from polyphonic music is proposed. It consists of an Independent Component Analysis and a subsequent partitioni...

We present an analysis of the bass drum circuit from the classic Roland TR-808 Rhythm Composer, based on physical models of the device’s many sub-circuits. A digital model based on this analysis (implemented in Cycling 74’s Gen ̃) retains the salient features of the original and allows accurate emulation of circuit-bent modifications—complicated behavior that is impossible to capture through bla...

Presented is a method of generating a full drum kit part for a provided kick-drum sequence. A sequence to sequence neural network model used in natural language translation was adopted to encode multiple musical styles and an online survey was developed to test different techniques for sampling the output of the softmax function. The strongest results were found using a sampling technique that ...

An analysis is made of the deflected forms assumed by an elastic strip when it is bent and stretched around a rigid drum. A summary is first given of the method of analysis used and the results obtained in a previous study where the drum width is equal to or greater than that of the strip. This work is then extended to the case where the strip width exceeds that of the drum. Defiected forms and...

Traditional drum machines and digital drum-kits offer users the ability to practice or perform with a supporting ensemble – such as a bass, guitar and piano – but rarely provide support in the form of an accompanying percussion part. Beatback is a system which develops upon this missing interaction through offering a MIDI enabled drum system which learns and plays in the user's style. In the co...

This thesis investigates the moment, when the drumstick hits the membrane of a drum. Experiments were conducted to obtain information about the interaction of drummer, drumstick and membrane during a single stroke. Using a modified drumstick, the force on the drumstick, the acceleration of the stick’s tip, the duration of the contact between stick and membrane and the sound of the drum were rec...

Low-intensity magnetic separators are widely used in the research works and the industry. Advancement in the magnetic separation techniques has led to an expansion in the application of this method in different fields such as enrichment of magnetic mineral, wastewater treatment, and medicine transfer in the human body. In the mineral processing industry, the main application of wet magnetic sep...

Drum–Buffer–Rope is a theory of constraints production planning methodology that operates by developing a schedule for the system’s first bottleneck. The first bottleneck is the bottleneck with the highest utilization. In the theory of constraints, any job that is not processed at the first bottleneck is referred to as a free good. Free goods do not use capacity at the first bottleneck, so very...
