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…

As one of the most important chemical reactions on the earth, the photosynthetic reaction has gained much attention. For example, foliage and algae possess superior abilities to harvest luminous energy from sunlight in photosynthetic reactions by capturing lights with the…

For a number of years already I’ve been absolutely fascinated, no, hypnotized, yes, hypnotized, by the Big Bang theory. What a fantastic theory that is. Have you heard of that one? It’s a big one. It’s a popular one. It…

The author aimed to explore the application of biological tactile in fast non-destructive meat freshness detection. Used WDW-20 electronic universal testing machine, surveyed chicken, pork and beef the pressure characteristic curves, analysed respectively the relationship between the pressure characteristic curve…

PKI system supports user authentication, message transmission, data integrity, message storage confidentiality, and the non-repudiation of operation. PKI can completely address e-commerce security requirements and PKI technology has been applied successfully in e-commerce as well. This article studies the system…

We estimate a localized control term for the Hamiltonian of spin orbit dynamics of Enceladus. The aim is to modify the perturbation locally by a smaller and simple but robust control term which makes the controlled Hamiltonian more regular. Poincare…

In this paper, it is demonstrated that saturation of the structure color exhibited by the multi-film systems can be determined by the thickness parameter of the layers of multi-films. To prove this principle, the multi-film of 1-quarter film system and…

The structure, geometrical shape and material are the three main parts of the prostheses. This research focuses on the geometrical shape analysis. The geometrical shape of human natural femoral head is similar to the ellipse, but, the artificial femoral head…
