The results of the shrub relative growth study showed that the models W =a +b(D2H)+c(D2H)2,W = a(D2H)b,W = a+bD+cC+dH,W = a+b(CV)+c(CV)2 were suitable for describing the rela-tionship between shrub morphology factors and total biomass,branch biomass,leaf biomass and root biomass.
Net primary production of the forcst(Pn) was 29.612t. hm-2.a-1, and that of trunk,branch,leaf,root,and fruit and flower,8.181(27.63%), 3.403(11.49%), 4.281(14.46%),13.165(44.46%), and 0.582(1.97%) respectively.
Iso-dryness distribution of boiler steam is based on the principle of phase separation, i.e., the two-phase fluid distributed to the branch lines are combined by two fluids, in which one fluid has higher dryness and another has lower dryness.
A branch-and-price algorithm for solving the cutting strips problem
After giving a suitable model for the cutting strips problem, we present a branch-and-price algorithm for it by combining the column generation technique and the branch-and-bound method with LP relaxations.
The double points may be the double points of either branch, or the intersection points of the two branches.
When the thickness is d >amp;gt; 2 Rg (radius of gyration), the polymer can crystallize into spherulites; when Rg >amp;lt; d >amp;lt; 2 Rg, a dense-branch morphology and dendrites could be found; when d >amp;lt; Rg, an "islands" structure could be obtained.
In addition, considering the non-convex and non-concave nature of the sub-problem of combinational optimization, the branch-and-bound technique was adopted to obtain or approximate a global optimal solution.
