This study investigates the relation between walking speed and the distribution of peak plantar pressure and compares a traditional ten-region subsampling (10RS) technique with a new technique: pedobarographic statistical parametric mapping (pSPM). Adapted from cerebral fMRI methodology, pSPM is a digital image processing technique that registers foot pressure images such that homologous struct...

The objective of this study was to investigate the effects of Feldenkrais Method balance classes on balance and mobility in older adults. This was a prospective non-randomized controlled study with pre/post measures. The setting for this study was the general community. A convenience sample of 26 community-dwelling older adults (median age 75 years) attending Feldenkrais Method balance classes ...

Walking speed was timed for male and female pedestrians on a public sidewalk with fast, slow, or no music playing in the background (n = 20 per condition). Pedestrians in the fast music condition walked more rapidly than those in the other two conditions. Slow music did not reduce walking speed, relative to the no music condition. Walking speed did not differ by gender in any of the three condi...

In this paper, we investigate the fractal-fractional Malkus Waterwheel model in detail. We discuss existence and uniqueness of a solution using fixed point technique. apply very effective method to obtain solutions model. prove with numerical simulations accuracy proposed method. put evidence effects fractional order fractal dimension for symmetric

A substantial body of evidence points to a cue-based direct-access retrieval mechanism as a crucial component of skilled adult reading. We report two experiments aimed at examining whether poor readers are able to make use of the same retrieval mechanism. This is significant in light of findings that poor readers have difficulty retrieving linguistic information (e.g., Perfetti, 1985). Our expe...

This paper introduces a new design of penternary inverter gate based on graphene nanoribbon field effect transistor (GNRFET). The penternary logic is one of Multiple-valued logic (MVL) circuits which are the best substitute for binary logic because of its low power-delay product (PDP) resulting from reduced complexity of interconnects and chip area. GNRFET is preferred over Si-MOSFET for circui...

with speed increasing in high-speed trains, due to limitations of other types of brakes, aerodynamic brake has become an important braking method. in this task to make better use of brake’s panel different configurations are examined and the best panel shape which provides the reasonable drag coefficient is introduced. the results of simulations are carried out with the computational fluid dyna...

experimental work was carried out to investigate the influence of impeller speed, granulation time, binder mass and their interactions on granule size distribution, mean size and binder content distribution in a conical high shear granulator. it was observed that the response of high shear granulation to changes in process parameters varies significantly from one operating condition to another....

in the present study a quasi 2-d numerical model is developed for calculating air concentration distribution in rapid flows. the model solves air continuity equation (convection diffusion equation) in the whole flow domain. this solution is then coupled with calculations of the free surface in which air content in the flow is also considered. to verify the model, its results are compared with a...
