Implantable medical device is an effective means of modern medical treatment and diagnosis. Its energy and data wireless transmission way become a research hot spot in bio-electronic field. The purpose of this paper is to study the influence of biological channel on the electromagnetic wave transmission characteristics in specific biological environment. In this paper, the biological tissues channel...
Presently, cycloid gears are widely applied in horologes, apparatuses and the meters. This paper makes double-circular-arc modified cycloid gears apply to power transmission system which has the high contact strength and the high lifetime. This paper starts from the transmission characteristics of cycloid gears, then double-circular-arc modified cycloid gears are proposed and whose mathematical model...
Degree distribution of nodes, especially a power law degree distribution, has been regarded as one of the most significant structural characteristics of social and information networks. Node degree, however, only discloses the first-order structure of a network. Higher-order structures such as the edge embeddedness and the size of communities may play more important roles in many online social networks...
To evaluate the reliability of the road network, the paper designed a mathematic model of travel time reliability index. Using the travel time reliability index, the paper analyzed the temporal and spatial distribution characteristics of Beijing road network reliability based on the floating car data. The results show that the travel time reliability is the lowest at the afternoon peak hour and there...
