Development of an Earthworm-Based Intestinal Soft Robot Equipped with a Gripper
An endoscopy is a tool that is used to examine the interior of a hollow organ or cavity of the body by inserting directly into the organ. However, intestinal endoscopy is not friendly to patients due to discomfort, and it can easily cause intestinal ...

Synchronization of organ pipes [PDF]
We investigate synchronization of coupled organ pipes. Synchronization and reflection in the organ lead to undesired weakening of the sound in special cases. Recent experiments have shown that sound interaction is highly complex and nonlinear, however, we show that two delay-coupled Van-der-Pol oscillators appear to be a good model for the occurring ...

The Dependence of Flue Pipe Airflow Parameters on the Proximity of an Obstacle to the Pipe’s Mouth
This paper describes the influence of the presence of an obstacle near the flue pipe’s mouth on the air jet, which directly affects the parameters of the sound generated by the flue pipe. Labial pipes of the most common types of mouth were tested.

Of Pipes and Patches: Listening to augmented pipe organs [PDF]
Pipe organs are complex timbral synthesisers in an early acousmatic setting, which have always accompanied the evolution of music and technology. The most recent development is digital augmentation: the organ sound is captured, transformed and then played back in real time.

Cavitation Impact Characteristics of Organ-Pipe Nozzle Under Gas Hydrate Reservoir Conditions
In order to improve the application effect of cavitation jet technology in the gas hydrate reservoir stimulation, the numerical simulation and experimental study were carried out to study the cavitation impact characteristics of organ-pipe nozzle-the key

On a Robust Descriptor of the Flue Organ Pipe Transient
The initial transient of an organ pipe is known to be of great influence to the perceived sound quality. At the same time, the unsteady process of the tone onset is essentially nonlinear and lacks exact repeatability, so the search for a robust ...
