We develop two families of mixed finite elements on quadrilateral meshes for approximating (u, p) solving a second order elliptic equation in mixed form. Standard Raviart–Thomas (RT) and Brezzi–Douglas–Marini (BDM) elements are defined on rectangles and extended to quadrilaterals using the Piola transform, which are well-known to lose optimal approximation of ∇ · u. Arnold–Boffi–Falk spaces rec...

Public education expenditure is the largest public and foundation of development in China. This paper uses Cobb-Douglas production function model to analyze relationship between China's economic growth, explores impact proportion primary, secondary tertiary on growth. The results show that has a positive effect accounts for contribution followed by higher primary education. research suggest Chi...

The attack levels of plant pest organisms (PPO) highly influence the productivity paddy rice farming. With increasing human awareness dangers using pesticides, especially for environment and health, PPO control prioritizes preventive by applying principles integrative management (IPM), which application healthy crop cultivation, routine observation, utilization natural enemies farmers as IPM ex...

A flux recovery technique is introduced and analyzed for the computed solution of the primal hybrid finite element method for second-order elliptic problems. The recovery is carried out over a single element at a time while ensuring the continuity of the flux across the interelement edges and the validity of the discrete conservation law at the element level. Our construction is general enough ...

Little is known of wood properties in trees that were initially suppressed and subsequently released from suppression. The purpose of this study was to assess differences in growth ring width, specific conductivity (Ks), tracheid dimensions, moisture content, and wood density in suppressed Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) and western hemlock (Tsuga heterophylla (Raf.) Sarg.) t...
