Investigation of a radial toolpath in single point incremental forming

open access: yesProcedia Manufacturing, 2020
Abstract Single point incremental forming (SPIF) is a sheet material forming process recognized for its potential performance in low to medium volume production due to precluding the need for high-investment stamping dies. This process forms blanks instead through the use of local deformations, traditionally imposed utilizing a hemispherically-shaped

The effect of canopy position on growth and mortality in mixed sapling communities during self-thinning [PDF]

open access: yes, 2009
This research investigates how species in the sapling phase differ in growth and survival depending on light availability (as estimated by canopy position) by means of tree-ring analysis and modelling mortality.

An Incremental Radial Basis Function Network Based on Information Granules and Its Application [PDF]

open access: yesComputational Intelligence and Neuroscience, 2016
This paper is concerned with the design of an Incremental Radial Basis Function Network (IRBFN) by combining Linear Regression (LR) and local RBFN for the prediction of heating load and cooling load in residential buildings. Here the proposed IRBFN is designed by building a collection of information granules through Context-based Fuzzy C-Means (CFCM ...
