In particular, our aim is twofold： （1） to provide measures of ICE specifically tailored to professional football businesses; and （2） to empirically investigate whether some dimensions of ICE, namely, human capital and relational capital efficiency, are positively associated with sporting performance, here used as a proxy for business performance. This paper develops a quantitative analysis of club-level panel data using the statistical technique known as mixed-effects linear regression for longitudinal analysis. The research spans a time period of five years and specifically the sporting seasons from 2007/2008 up to 2011/2012. The empirical findings of this study provide tentative evidence that ICE, especially as far as relational capital is concerned, is positively associated with on-pitch performance of professional football businesses. On the counterpart, results for the impact of human capital efficiency （HCE） do not consistently come out with the （positive） expected signs. More specifically, our findings suggest that relational capital efficiency, meaning the ability to develop and nurture positive business relationship with relevant external stakeholders, is a significant consideration for football club managers; on the other, they might shed light on the actual business model of professional football clubs that, in our analysis, does not appear consistent with the long-held hypothesis of winning maximization. The main limitation of this study lies in the fact that our indicators do not fully capture all relevant dimensions of the intellectual capital （IC） construct.展开更多

The Lagrangian trajectory method is used in the three dimensional simulation for floating rates of fxazil ice particles along a 180° bend channel. The velocity profiles in longitudinal and transverse directions, the turbulence intensity, and the residual pressure are simulated. Under the condition of gravitational similarity, the simulated floating rates of frazil ice particles in the model bend channel and the prototype bend channels are compared. Results indicate that the profiles for floating rates of ice particles for flows in the model channel are similar to those in the prototype bend channels. The simulated floating rates of ice particles are clearly higher along the convex bank than along the concave bank at each cross section. For the prototype bend channel in a large model scale, the variation of floating rate across each cross section is relatively small.展开更多

Using the finite element method (FEM), we compare these two kinds of LAs. The FEM result shows that the flat-type permanent magnet LA has higher efficiency and larger output specific power than the tubular one, therefore more suitable for FPLAs, and that the alternator design can be optimized with respect to the permanent magnet length as well as the air gap.展开更多
