Introduction Patient motion is a significant problem for MR imaging. Spiral Projection Imaging (SPI) is a 3-D imaging sequence, which provides enough data to deduce all six degrees of freedom of bulk motion [1]. Motion correction has been successfully demonstrated for quadrature coil data (both real and synthetic), by comparing data from individual planes [2,3] (Fig. 1). The extension to multi-...

In this paper a fraud detection method is proposed which user behaviors are modeled using two main components namely the un-normal trend analysis component and scenario based component. The extent of deviation of a transaction from his/her normal behavior is estimated using fuzzy membership functions. The results of applying all membership functions on a transaction will then be infused and a f...

The study provided validity evidence for a fourfold taxonomy of work-family balance that comprises direction of influence (work to family vs. family to work) and types of effect (work-family conflict vs. work-family facilitation). Data were collected from 189 employed parents in China. The results obtained from a confirmatory factor analysis supported the factorial validity of the fourfold taxo...

AIM To study the effect of balance intervention program using the "FIFA 11+" program on static and dynamic balance and kicking accuracy of young soccer players. METHODS Twenty young soccer players were allocated to experimental (n = 10) or control (n = 10) groups. The experimental group performed the "FIFA 11+" program three times a week for six weeks. The control group performed their normal...

introduction: postural control is regarded to as a critical element in physical activities and as an important factor in performing athletic skills. previous studies have reported controversial results about the effects of different training programs and also of detraining on the postural control. this study aimed to evaluate the effect of two-, four-, and six-week detraining after a period of ...

A high-performance magnetic levitation haptic interface has been developed to enable the user to interact dynamically with simulated environments by holding a levitated structure and directly feeling its computed force and motion responses. The haptic device consists of a levitated body with six degrees of freedom and motion ranges of 5 mm and 3.5 degrees in all directions. The current device c...

BACKGROUND We have recently demonstrated the efficacy of balance training in addition to Pulmonary Rehabilitation (PR) at improving measures of balance associated with an increased risk of falls in individuals with Chronic Obstructive Pulmonary Disease (COPD). Few knowledge translation (KT) projects have been conducted in rehabilitation settings. The goal of this study was to translate lessons ...

The purpose of this study was to determine whether measures of impairment (i.e., muscle strength, balance), personal factors (i.e., comorbidities, demographic information) and amputation specific variables (i.e., time since amputation, cause of amputation, level of amputation) were able to predict performance on the six-minute walk test, a measure of activity limitation, in individuals with low...

All moving objects possess six degrees of freedom – three linear and three rotary. The task of a linear motion guideway is to eliminate, as closely as possible, five of these degrees of freedom, leaving a single rotary or linear axis of motion. Air bearings are the purest and highest performance means of defining linear or rotary motion, and have substantial advantages over conventional mechani...
