    • System, method and software product for numerically simulating structural behaviors of an engineering product in compressible and near-incomprssible region is disclosed. Meshfree enriched finite element method (ME-FEM) is used for such numerical simulation. ME-FEM requires an engineering product be represented by a FEM model comprising a plurality of finite elements. Finite elements used in the ME-FEM are generally low-order finite elements. Each of the finite elements in the FEM model is enriched by at least one meshfree enriched (ME) node located within the element's domain. Each ME node has additional degrees-of-freedom for the element it belongs independent from those of the corner nodes. A displacement based first-order convex meshfree approximation is applied to the ME node. The convex meshfree approximation has Knonecker-delta property at the element's boundary. The gradient matrix of ME-FEM element satisfies integration constraint. ME-FEM interpolation is an element-wise meshfree interpolation that is discrete divergence-free at the incompressible limit.
    • 公开了一种用于数值模拟工程产品在可压缩和近不可逆区域中的结构行为的系统,方法和软件产品。 无网格富集有限元法(ME-FEM)用于这种数值模拟。 ME-FEM要求工程产品由包括多个有限元素的FEM模型表示。 ME-FEM中使用的有限元素通常是低阶有限元。 FEM模型中的每个有限元素都由位于元素域内的至少一个无网格富集(ME)节点来丰富。 每个ME节点对于其所属的元件具有额外的自由度,独立于角点节点。 基于位移的一阶凸无网格近似被应用于ME节点。 凸无网格近似在元素边界处具有Knonecker-delta属性。 ME-FEM元素的梯度矩阵满足积分约束。 ME-FEM插值是在不可压缩极限处为离散无差异的元素无网格内插。

    • A force bearing monitor apparatus for sports shoes includes a first accelerometer module located at a rear end of a sole of a shoe and a second accelerometer module located at a front end of the sole to measure alterations of a first acceleration and a second acceleration borne by the shoe when a user is stridden and stepped during running. Through generation sequence of the alterations of the first and second accelerations, an exercise mode is determined. And through processing of a first signal processing unit and an interrelation processing unit, a first reacting force and a second reacting force are derived, and the ratio of the first and second reacting forces is obtained to serve as a control factor to adjust softness and hardness of the sole. According to the exercise mode, the softness and hardness of the sole can be made in response to the ground.

    • The table lamp contains a lamp base and an extension tube plugged vertically into the lamp base. A curved transparent light tube is attached along its entire length to a parallel and also curved back cover. The combination is joined to a top end of the extension tube. Two light generation assemblies are provided at the two ends of the light tube, respectively, each sequentially composed of a lens, a lens ring, a light emitting diode, a power circuit, a heat dissipation plate, and a heat dissipation element. The light from the light emitting diodes is projected into the light tube and, with a reflection layer along the inner wall of the light tube, the light is uniformly reflected towards the area beneath the table lamp.
