Cutting stock problems have numerous applications in a wide variety of manufacturing industries [20], from cutting steel and other metals to cutting paper, textiles and lumber. As a result, the CSP has been studied extensively. Models for the CSP may use a variety of objectives, such as minim...

Gao’s method [6] was developed to compress Chinese white poplar wood by adjusting the moisture and temperature distributions within the lumber which is also based on thermal compression. The wood is soaked to adjust wood moisture content instead of steam preheating. The temperatures of the upper...

Since the pest will go through the growth process from larvae to adult inside the host tree, its body size and the area of cross-sectional surface gnawed inside the host tree will also change. Assuming that the cross-sectional area formed by the pest in the larval stage is the minimum ...
The sample size was determined using G*Power 3.1.2 (Universität Düsseldorf, Germain) [25]. With a significance level and power set at 0.05 and 0.80, respectively, and an effect size at 0.15, the minimum sample size was estimated as 125. Estimating potential drop-out rate of 5%, the ...
