"Conventional census-based measures of population mobility are conceptually abstruse, ignore multiple moves and obscure the diversity of human migration experience. This paper explores three alternatives and outlines their strengths and limitations. Application of life table techniques to convert transition rates to migration expectancies generates measures that are more readily understood, aut...

This paper is focused on a discussion of parameters and heuristics that are expected to assist multihop routing in becoming more sensitive to node mobility. We provide a discussion concerning existing and a few proposed parameters. Moreover, the work also discusses two new heuristics based on the notion of link duration. The heuristics are compared based on a meaningful set of scenarios that at...

A systematic literature review was conducted to evaluate the effectiveness of interventions within the scope of occupational therapy practice to improve or maintain the driving performance and community mobility of older adults with low vision. The results of this review identified a limited number of articles-eight-that met the inclusion criteria. Identified intervention strategies included th...

This work describes a cryogenic, electro-optically -switched Yb:YAG laser that generates 114-W average TEM power with 47% optical-to-optical efficiency. Pulse repetition frequency is 5 kHz, pulse duration is 16 ns full-width at half-maximum, and is less than 1.05.

Adaptive ad hoc network routing protocols can obtain improved performance over a wide variety of node mobility and network dynamics when compared with non-adaptive protocols. A mobility metric, which quantifies the effect of node movement in order to measure the communication potential in a mobile network, can be used to develop an adaptive ad hoc network protocol. We provide a set of requireme...

Aging has negative effects on motor and cognitive functions, therefore finding appropriate strategies to prevent the decline of these functions is necessary. It seems that cardiovascular fitness obtained by aerobic activity is a physiological mediator that explains the relationship between physical activity and improved cognitive performance. The aim of this research was to assess the effect...
