The two end surface revolution axis relative rotation system and a kind of two qualities relative rotation system unified non-linear dynamics model are established, in the non-linear resiliency and the generalized damping force. And the chaos movement performance of unification…

The basis of our study is to identify the discriminating groups that are present in the observations as well as looking into the details of the classification of the observation that forms each group. The observations were obtained as a…

This paper investigated the effects of aerodynamic force and inertial force on the structure deformation of wing. The aerodynamic force was tested from the wind tunnel experiment. The study indicated the quantity of aerodynamic force and inertial force is equal.…

This paper studies the meaning, nature of extension correspondence and analyzes its superiority in data prediction in extension group decision-making by analyzing the distance and bit value of the correlation function. It puts forward the model and steps of data…

Aiming at the lightweight filler particles with good dielectric properties in the composites, helical Spirulina platensis were chosen as templates to produce microscopic helical soft-core filler particles by an electroless deposition technique. The morphology and appearance of the coated Spirulina…

To study the interaction between the player's actions and environment in economic management game such as launching some projects with pollution in a certain area, we consider the relation between the player’s interests and the environment. We introduce a so-called…

By imitating the jetting flow feature of shark gills，a bionic jetting model is established by arranging round outlets on a flat plate. The drag reduction effect under different jetting directions are explored using numerical simulation method when the main flow…

From the view of bionic, optimizing and engineering the corrugated bionic needle with polynomial regression. The results showed that; the width of the ripple with quadratic effect plays a major role in reducing resistance; the impact of non-smooth structure’s spacing…

Swordfish is the fastest fish in the world, which can reach a high speed of 110km/h. Depending on the swing of the caudal fin, swordfish gets the power of swimming. The caudal fin of the swordfish shows crescent and wide…

Constructing the accurate digital model of vessel networks is critical to vascular tissue engineering, in which the segmentation of vessel plays an important role. However, the existing segmentation methods are not able to achieve the goal of accurate segmentation of…
