Flexible models with evolving structure [PDF]

Proceedings First International IEEE Symposium Intelligent Systems, 2003
Summary: A type of flexible model in the form of a neural network (NN) with evolving structure is discussed in this study. We refer to models with amorphous structure as flexible models. There is a close link between different types of flexible models: fuzzy models, fuzzy NN, and general regression models. All of them are proven universal approximators

Omnidirectional Structured Light in a Flexible Configuration [PDF]

Sensors, 2013
Structured light is a perception method that allows us to obtain 3D information from images of the scene by projecting synthetic features with a light emitter. Traditionally, this method considers a rigid configuration, where the position and orientation of the light emitter with respect to the camera are known and calibrated beforehand.

Suppression of transverse vibration of elevator rope using vertical vibration of counterweight

Nihon Kikai Gakkai ronbunshu, 2015
An elevator rope for high-rise building is forcibly excited by the displacement of the building caused by earthquakes and wind forces. In high-rise building, the elevator rope may resonate with the natural frequency of the building; hence, effective ...
