Surface fairing, generating free-form surfaces satisfying aesthetic requirements, is important for many computer graphics and geometric modeling applications. A common approach for fair surface design consists of minimization of fairness measures penalizing large curvature values and curvature oscillations. The paper develops a numerical approach for fair surface modeling via curvature-driven e...
The bifurcation diagram for the buckling of a planar elastica under a load λ is made up of a “trivial” branch of unbuckled configurations for all λ and a sequence of branches of buckled configurations that are connected to the trivial branch at pitchfork bifurcation points. We use several perturbation expansions to determine how this diagram perturbs with the addition of a small intrinsic shape...
Carbon dioxide (CO2) enrichment in greenhouses could be used for reduction of production time and increasing plant growth and quality. To evaluate the effects of different concentrations of CO2 on growth traits of two ornamental Ficus species (Ficus benjamina and Ficus elastica), a split plot experiment, based on completely randomized design with three replications, was conducted in the greenho...
