Abstract:
... The collision between a single-sphere and a double-sphere is measured in this study by a high speed camera to verify the fundamental issue of tangential and normal restitution coefficients for a particular shape of double-sphere. In this experiment, a single-sphere moves and collides on a stationary double-sphere, and a high speed camera is used to capture the collision of them. Numerous tests wer ...

Abstract:
... Discounting refers to the way in which the value of an outcome depends on the delay until it is obtained. If an organism’s discount function is known, then its rate of discounting at any delay can be found. If the function is not known, the normalised area under an estimate of the discount function has been used as a measure that summarises the strength of discounting over a range of delays. We pr ...

Tree diameter increment (ΔDBH) is a key component of a forest growth and yield model as predictions are passed to other submodels and tree-level estimates are scaled up to represent plot- and stand-level measures. A common problem faced in mixed-species stands is that ΔDBH needs to be characterized for numerous species, each with varying growth rates, shade tolerances, and competitive abilities. I ...
