mathematics curriculum in schools is always a key position and is considered as an essential knowledge. so it is taught in the first years of school curriculum. this knowledge has focused on calculating the initial period. so this part of mathematics play an important role in lives of all people so this knowledge is essential for learning today. in the early years of primary school children, th...

This paper provides the first evidence of geographic concentration of foreign visitors in Japan, using a new data on nights spent by foreign visitors in each region. Using locational Gini coefficients, I show that foreign visitors are more geographically concentrated than Japanese visitors and the level of geographical concentration vary across source countries. In addition, I employ gravity eq...

In this response to Burt Neuborne’s Who’s Afraid of the Human Rights Commission, the author seeks to challenge many of the assumptions underlying Neuborne’s model calling for increased focus on preventative measures by the Human Rights Commission. In Part I, the author addresses Neuborne’s moral arguments and concludes that he undermines the ability of sanctions to deter future conduct. In Part...

Weeds are a major threat to biodiversity globally degrading natural areas of high conservation value. But what are our attitudes about weeds and their management including weeds in national parks? Do we know what a weed is? Do we consider weeds a problem? Do we support their management? Are we unintentionally spreading weeds in parks? To answer these questions, we surveyed visitors entering a l...

Abstract In this paper, we introduce a kind of combinatorial numbers, D − Stirling numbers, and its special cases. An exponential generating function of the D − Stirling numbers is given. We also present recurrence relations, monotonicity, and limiting properties of the D−Stirling numbers. Applications to statistical probability function estimation and restricted occupancy theory are provided. ...

In this paper we present a novel vision-based system for the automated production of personalised video souvenirs for visitors in leisure and cultural heritage venues. Visitors are visually identified and tracked through a camera network. The system produces a personalized DVD souvenir at the end of a visitor’s stay allowing visitors to relive their experiences. We analyze how we identify visit...

Today very popular Web portal sites, social networking sites, online media sites, commerce sites, etc., provide platforms for millions of visitors to visit daily and express their opinions on a wide variety of subjects. The site operators strive to increase the number of visitors, and the visitors often make use of several means at their disposal to participate in the formation of collective op...

Posted facial expressions on social networks have been used as a gauge to assess the emotional perceptions of urban forest visitors. This approach may be limited by randomness visitor numbers and park locations, which not accounted for range data in local tree inventories. Spatial interpolation can predict stand characteristics detect their relationship with posted expressions. Shaoguan was stu...

A connection between real poles of the growth functions for Coxeter groups acting on hyperbolic space of dimensions three and greater and algebraic integers is investigated. In particular, a certain geometric convergence of fundamental domains for cocompact hyperbolic Coxeter groups with finite-volume limiting polyhedron provides a relation between Salem numbers and Pisot numbers. Several examp...

according to performed classification by ramsar convention (1971), choghakhor is one of the most valuable wetlands of iran. despite of high abilities of perspective and variation of habitats, tourism valuations are not considered. in this study, promenade valuation choghakhor wetland was estimated by using zonal travel cost method. these methods is based on using map, sight, social-economical c...
