OBJECTIVES Asymmetrical posture during static stance has been identified as a common problem in persons with hemiplegia. This study examined the effect of an activity-based therapy regimen on symmetric weight bearing and midline position of center of gravity (COG) in three adult subjects with hemiplegia. METHOD An ABAB single-subject design was used. The intervention program, including sandin...
BACKGROUND AND AIMS There is an important role of the neck sensory motor system in control of body posture and balance, and it is reasonable to believe that the jaw sensory motor system can directly and indirectly influence the modulation of the postural control system. The purpose of this study was to evaluate possible effects of dynamic jaw position while chewing on the postural control syste...
Unilateral upper extremity lymphedema deteriorates the postural stability in breast cancer survivors
AIM OF THE STUDY There is little known about any change in postural balance caused by asymmetrical volume increase due to unilateral upper extremity lymphedema in patients who underwent breast surgery. The aim of this study was to determine whether there is a change in postural balance by measuring postural sway velocity (PSV), center of gravity (CoG) displacement and directional control (DCL) ...
Tire pressure has a significant influence on the driving safety of road vehicles; therefore, it is mandatory in many countries to equip all new vehicles with tire monitoring system (TPMS). There are two types TPMSs use: direct TPMS (dTPMS) and indirect (iTPMS), both which have made improvement last decade. The most accurate iTPMS methods used commercial apply Fourier transform wheel speed senso...
A cluster imaging technique for Transmission Electron Microscopy with a direct detection CMOS pixel sensor is presented. Charge centre-of-gravity reconstruction for individual electron clusters improves the spatial resolution and thus the point spread function. Data collected with a CMOS sensor with 9.5×9.5 μm pixels show an improvement of a factor of two in point spread function to 2.7 μm at 3...
The starting point of the paper presented are the well-known defuzzification procedures on the one hand and approaches to axiomatize the concept of defuzzification, on the other hand. We present a new attempt to build up an axiomatic foundation for defuzzification theory using the theory of groups and the theory of partially ordered sets, and in particular, the theory of GALOIS connections.
Focusing gaze on a target helps stabilize upright posture. We investigated how this visual stabilization can be affected by observing a target presented under different gaze and viewing angles. In a series of 10-second trials, participants (N = 20, 29.3 ± 9 years of age) stood on a force plate and fixed their gaze on a figure presented on a screen at a distance of 1 m. The figure changed positi...
An analytical expression of an Airy-Gauss beam passing through a fractional Fourier transform (FRFT) system is derived. The normalized intensity distribution, phase distribution, centre of gravity, effective beam size, linear momentum, and kurtosis parameter of the Airy-Gauss beam are demonstrated in FRFT plane, respectively. The influence of the fractional order p on the normalized intensity d...
Saccades directed to simple two-dimensional (2D) target shapes under instructions to look at the target as a whole land near the center of gravity (COG) of the shape with a high degree of precision (He & Kowler, 1991; Kowler & Blaser, 1995; McGowan, Kowler, Sharma, & Chubb, 1998; Melcher & Kowler, 1999; Vishwanath, Kowler, & Feldman, 2000). This pattern of performance has been attributed to the...
PURPOSE To evaluate potential contributions of broadband spectral integration in the perception of static vowels. Specifically, can the auditory system infer formant frequency information from changes in the intensity weighting across harmonics when the formant itself is missing? Does this type of integration produce the same results in the lower (first formant [F1]) and higher (second formant ...
