background : to the best of the authors’ knowledge, to date, no systematic study has been carried out in tabriz city to investigate the extent, frequency, causes, and major outcome(s) of falling accidents in the houses of rural and urban areas of this city. the current study was, therefore, undertaken to address some of these issues. methods: in this cross-sectional retrospective study, 43170 i...

background: fear of falling is not only a risk factor for falls, but it is also an important clinical predictor of functional decline in older adults. this study identified sex differences in fear of falling and related factors in older adults with low grip strength. methods: the data of 902 older adults from the 2012 korean national survey, conducted as a research project by the korea employme...

one of the modern paradigms to develop an application is object oriented analysis and design. in this paradigm, there are several objects and each object plays some specific roles in applications. in an application, we must distinguish between procedural semantics and declarative semantics for their implementation in a specific programming language. for the procedural semantics, we can write a ...

Object tracking is one of the important tasks in the field of computer vision. Some of the areas which need Visual object tracking are surveillance, automated video analysis, etc. Mean shift algorithm is one of the popular techniques for this task and is advantageous when compared to some of the other tracking methods. But this method would not be appropriate in the case of large target appeara...

Objectives: Balance disorder is one of the most common problems after stroke causes falling and fear of falling in some patients. The balance based video games are newly used in people with motor problems. It is very important to use different interventions for balance issues. The aim of this study is to determine the effectiveness of videogame on balance and fear of falling in one participant....

Previous studies reported a non-native word learning advantage for bilingual infants at around 18 months. We investigated developmental changes in infant interpretation of sounds that aid in object mapping. Dutch monolingual and bilingual (exposed to Dutch and a second non-tone-language) infants' word learning ability was examined on two novel label-object pairings using syllables differing in ...

We present a novel approach for a virtual granular material interactive manipulation with force feedback. A user can interactively change a height-field model of sand by dragging objects inside. The virtual sand behaves like real sand moving to the sides and falling back, filling holes and irregularities on the surface. The dragging object position is controlled by a haptic device that provides...

Successful object recognition is essential for finding food, identifying kin, and avoiding danger, as well as many other adaptive behaviors. To accomplish this feat, the visual system must reconstruct 3-D interpretations from 2-D "snapshots" falling on the retina. Theories of recognition address this process by focusing on the question of how object representations are encoded with respect to v...
