The aim of this study is to scientifically design sneakers for athletes to avoid the negative effects of uncomfortable sneakers and thus improve their sports training level as well as training performance. On the basis of polyvinylidene fluoride (PVDF) sensing materials, PVDF sensors on the robot foot were designed and foot pressure data were detected. The detailed results showed that PVDF sensors had good performances. The PVDF sensors on the robot foot could effectively distinguish different materials, body weights and exercise modes as well as judge the fitness, which provided powerful data support and help for the scientific design of athletes' sneakers.

Aims Although shrubs are an important component of forests, their role has not yet been considered in forest biodiversity experiments. In the biodiversity-ecosystem functioning (BEF) experiment with subtropical tree species in south-east China (BEF-China), we factorially combined tree with shrub species-diversity treatments. Here, we tested the hypotheses that shrub survival differs between the 10 planted shrub species, with lower survival rates of late-than earlysuccessional species and is affected by environmental conditions, such as topography and top soil characteristics, as well as by biotic factors, represented by tree, shrub and herb layer characteristics. Methods We analyzed the survival of 42 000 shrub individuals in 105 plots varying in tree and shrub species richness of the BEF-China project four years after planting. Shrub survival was analyzed with generalized linear mixed effects models at the level of individuals and with variance partitioning at the plot level. Random intercept and random slope models of different explanatory variables were compared with respect to the Bayesian Information Criterion (BIC). Important Findings Survival rates differed largely between the 10 shrub species, ranging from 26% to 91% for Ardisia crenata and Distylium buxifolium, respectively. Irrespective of species identity, single abiotic factors explained up to 5% of species survival, with a negative effect of altitude and slope inclination and a positive effect of the topsoil carbon to nitrogen ratio, which pointed to drought as the major cause of shrub mortality. In contrast, neither tree nor shrub richness affected shrub survival at this early stage of the experiment. Among the biotic predictors, only herb layer species richness and cover of the dominant fern species (Dicranopteris pedata) affected shrub survival. Overall, our models that included all variables could explain about 65% in shrub survival, with environmental variables being most influential, followed by shrub species identity, while tree species diversity (species richness and identity) and herb layer characteristics contributed much less. Thus, in this early stage of the experiment the biotic interactions among shrubs and between shrubs and trees have not yet overruled the impact of abiotic environmental factors. © The Author 2017.

From the basic concept of product funny design, this paper explored its esthetic concept sources, focused on the feelings of the product experience and the pleasure brought to our lives. It is advocated to concern funny product design when we design household products, and to use new materials and processes, so that the product design is more close to people, and achieve the goal of “Human oriented design”, and then we can feel our product in experience, realized the emotional value of the product. © (2014) Trans Tech Publications, Switzerland.

Literature, logical reasoning, and other research methods are used in this thesis, classification, and analysis of the definition of incentive methods; motivation methods are also stated in this article, and this article also combines with students’ psychological characteristics, different teaching content, and teaching methods. It discusses how to stimulate students’ interest in sports and mobilize students’ enthusiasm and initiative by motivation methods in the sports teaching, thus promoting teaching effectiveness, improving teaching quality, and providing some theoretical reference for improving the quality of teaching physical education. The results showed that we have already done some research on the stimulation methods in teaching sports, but few are studied as combining with the psychological characteristics of students. © 2015 Taylor & Francis Group, London.
