—In this paper, we investigate the dynamic rate allocation for multipath routing with the node-disjoint paths in cognitive radio ad hoc networks composed of selfish secondary users (SUs) which are unwilling to forward the packets. We model the path stability factor of each path under a certain traffic session by distributing available channel in view of the carrier frequency of the available u...

PURPOSE This study assessed overall quality of life of caregivers, using a path model in which burden was conceptualized as distinct from well-being. DESIGN AND METHODS Data were drawn from a representative sample of caregivers to dementia and nondementia care receivers in British Columbia, Canada (N = 243). The model used was based on a previously proposed stress/appraisal path model and use...

Probabilistic Computation Tree Logic (PCTL) and Continuous Stochastic Logic (CSL) are often used to describe specifications of probabilistic properties for discrete time and continuous time, respectively. In PCTL and CSL, the possibility of executions satisfying some temporal properties can be quantitatively represented by the probabilistic extension of the path quantifiers in their basic Compu...

The purpose of this study is to characterize the indoor channel for IEEE 802.16 (WiMAX) at 3.3 to 3.6 GHz frequency. This work presents a channel model based on measurements conducted in commonly found scenarios in buildings. These scenarios include closed corridor, wide corridor and semi open corridor. Path loss equations are determined using log-distance path loss model and a Rayleigh multipa...
