Special Issue Information

Dear Colleagues,

Forest products, as our most-used renewable resource, are traditionally used in the building sector; however, supplies are finite. With the accelerated advancement of new technology, increasing studies about wood quality have been conducted in response to the rapid development of wood in construction materials. However, this Special Issue will provide insight into how wood technology is used to improve wood quality in various kinds of forest products, as opposed to construction materials only. Through the insights of these contributing papers, we hope to help solve the supply shortage of forest products so as to achieve effective resource management and use.

This Special Issue welcomes authors who are engaged in studying wood science, wood technology, or wood processing to submit papers.

Potential topics include, but are not limited to:

  • Thermal modification and protection of wood;
  • Wood-filled composite materials;
  • Building materials and technologies;
  • Wood science and processing;
  • Drying and thermal moisture treatment of materials.

A function from the domain (x-set) to the codomain (y-set) connects each x element to precisely one y element. Since each x-point originating from the domain corresponds to two y-points on the graph of a closed curve (i.e., circle, ellipse, superellipse, or ovoid) in a rectangular (Cartesian) diagram, it does not fulfil the function’s requirements. This non-function phenomenon obstructs the nonlinear regression application for fitting observed data resembling a closed curve; thus, it requires transforming the rectangular coordinate system into a polar coordinate system. This study discusses nonlinear regression to fit the circumference of a tree stem’s cross-section and its sapwood–heartwood transition by transforming rectangular coordinates (x, y) of the observed data points’ positions into polar coordinates (r, θ). Following a polar coordinate model, circular curve fitting fits a log’s cross-sectional shape and sapwood–heartwood transition. Ellipse models result in better goodness of fit than circular ones, while the rotated ellipse is the best-fit one. Deviation from the circular shape indicates environmental effects on vascular cambium differentiation. Foresters have good choices: (1) continuing using the circular model as the simplest one or (2) changing to the rotated ellipse model because it gives the best fit to estimate a tree stem’s cross-sectional shape; therefore, it is more reliable to determine basal area, tree volume, and tree trunk biomass. Computer modelling transforms the best-fit model’s formulas of the rotated ellipse using Python scripts provided by Wolfram engine libraries. Full article
