The study of the women's competitive gymnastics, picking out 60 young women whose bodies are close to the physiological index of competitive gymnastics athletes to try on. Using the methods of the subjective and objective experiments, the paper makes a research into pressure comfort when people try on seamless gymnastics clothing in the stillness and movement conditions. Applying the parameter interval...
A class of correlative three-dimensional (3D) chaotic and four-dimensional (4D) hyper chaotic switchable systems is built. 4D hyper chaotic system is designed bases on 3D Lorenz system family. Some of its basic dynamical properties are studied in detail, such as the feature of equilibrium, the phase portraits of hyper chaotic attractor, the Lyapunov exponent and the fractal dimension. Furthermore,...
Since 1994, China has provided the network services. Right now, the internet penetration rate has been reached 34.3% in 2010; China has become the world's second largest e-commerce market. The consumer became more and more complex and pragmatic, they got and share the information online, and those will affect the company's marketing implementation, especially the CRM. So, we propose the new way to...
Greedy forwarding with geographical locations in a wireless sensor network may fail at a local minimum. In this paper we propose to use conformal mapping to compute a new embedding of the sensor nodes in the plane such that greedy forwarding with the virtual coordinates guarantees delivery. In particular, we extract a planar triangulation of the sensor network with non-triangular faces as holes, by...
