Recently, with the rapid development of mobile devices and the crowdsourcing platforms, the spatial crowdsourcing has attracted much attention from the database community. Specifically, spatial crowdsourcing refers to sending a location-based request to workers according to their positions, and workers need to physically move to specified locations to conduct tasks. Many works have studied task...

On one hand, an all-electric ship may take over and support operator tasks in order to improve the operational effectiveness and efficiency on board of a ship. At the other hand, information processing demands seem to increase substantially for the operators in such a ship. Recently, a Cognitive Task Load analysis method was developed for the design of operator tasks and computer support, aimin...

This study presents the effect of porosity on mechanical behaviors of a power distribution functionally graded beam. The Euler-Bernoulli beam is assumed to describe the kinematic relations and constitutive equations. Because of technical problems, particle size shapes and micro-voids are created during the fabrication which should be taken into consideration. Two porosity models are proposed. T...

Colchicine, a potent neurotoxin derived from plants, has been recently introduced as a degenerative toxin of small pyramidal cells in the cortical area 1 of the hippocampus (CA1). In this study, the effect of the alkaloid in CA1 on the behaviors in the conditioning task was measured. Injections of colchicine (1,5 μg/rat, intra-CA1) was performed in the male Wistar rats, while the animals were s...

the present study examines the hypothesis that the attitudes and behaviors of people toward dental health practice varies with such factors as locality (urban- rural) age and levels of education. for this study 1085 urban and 871 rural heads of households have been interviewed. the results indicated that locality and age influences the behaviors of the respondents but the general attitude leads...
