In this study, we propose two models for predicting people's activity. The first model is the pedestrian distribution prediction (or postdiction) model by multiple regression analysis using space syntax indices of urban fabric and people distribution data obtained from a field survey. The second model is a street choice model for visitors using multinomial logit model. We performed a questionna...

In international packages Wireless Sensor Networks (WSNs) plays a critical pose nowadays. The value of WSNs basically depends on the statistics collection scheme. Several data collection schemes such as multipath, chain, tree, and cluster and hybrid topologies are presented in literature for congregation records in WSNs. but, the prevailing facts collection schemes fail to offer an assured reli...

Barilius bendelisis is an important food fish and a demanding ornamental species in India. Despite its great economic importance, several wild populations have been suffering drastic reduction. The genetic variability within population is extremely useful for gathering information on individual’s identity, breeding patterns, degree of relatedness and disturbance of genetic variation among them....

This study focuses on the carrying capacity estimation for Darkesh forest in Northeast Iran. Four factors were used for estimating the carrying capacity including tourist flows, size of the area, optimum space available for each tourist, and visiting time. Results showed that the physical carrying capacity was 2727 ha or 165 visitors/day, while the real carrying capacity was 2719 ha or 132 visi...
