introduction: users’ performance and their interaction with information retrieval systems can be observed in development of their mental models. users, especially users of health, use mental models to facilitate their interactions with these systems and incomplete or incorrect models can cause problems for them . the aim of this study was the adjustment and development of health user’s mental m...

this paper presents the thermal vibration analysis of double-layer graphene sheet embedded in polymer elastic medium, using the plate theory and nonlocal continuum mechanics for small scale effects. the graphene is modeled based on continuum plate theory and the axial stress caused by the thermal effects is also considered. nonlocal governing equations of motion for this double-layer graphene s...

the permeability and tortuosity of pore-scale two and three-dimensional random porous media were calculated using the lattice boltzmann method (lbm). effects of geometrical parameters of medium on permeability and tortuosity were investigated as well. two major models of random porous media were reconstructed by computerized tomography method: randomly distributed rectangular obstacles in a uni...

Objective: The present study compared results on the Wechsler Adult Intelligence Scale-Revised (WAIS-R) among adult patients with attention-deficit/hyperactivity disorder (AD/HD) and those with Asperger’s disorder (AD). Method: WAIS-R results were compared between 16 adults with AD/HD (8 men and 8 women; mean age, 33.81 years; mean full-scale IQ, 101.5) and 15 adults with AD (12 men and 3 women...

Gaussian scale-space is considered to be a modern bottom-up tool in computer vision. The Amer-ican and European vision community, however, is unaware of the fact that Gaussian scale-space has already been axiomatically derived in 1959 in a Japanese paper by Taizo Iijima. This result formed the starting point of an entire world of linear scale-space research in Japan ranging from various axiomat...

abstract background: labor is a physiologic process, and consideration of labor pain and relieving that is among the major components of maternal care. application of some labor position can lay the fetus better in pelvic canal direction. the present study aimed to investigate the effect of laying the mother in three labor positions on the pain severity in the second, third, and fourth stages o...
