Stair climbing is one of the most challenging tasks for vehicles, especially when transporting people and heavy loads. Although many solutions have been proposed demonstrated in practice, it necessary to further improve their ability safety. This paper presents a systematic review scientific engineering stair literature, providing brief descriptions mechanism method operation highlighting advan...

The purpose of this study is to investigate the kinematics in humans during stair climbing and the influence of stair slope variation on gait cycle .The analysis of biomechanical aspect involved in stair ascent and descent can add to our understanding of the diverse and complicated processes involved in human locomotion and also be useful in the design of private and public environments where s...

The aim of the study was to investigate differences in frontal plane knee kinetics, onset timing and duration of the gluteus medius (GMed), adductor longus (AL), and vastus medialis oblique (VMO) during stair ambulation between those with and without patellofemoral pain syndrome (PFPS). Twenty PFPS patients and twenty healthy participants completed stair ambulation while surface electromyograph...

STUDY DESIGN Cross-sectional case-control design. BACKGROUND Although the etiology of patellofemoral pain syndrome (PFPS) is not completely understood, there is some evidence to suggest that hip position during weight-bearing activities contributes to the disorder. OBJECTIVE To compare the knee and hip motions (and their coordination) during stair stepping in female athletes with and withou...

Despite its apparent popularity in fifteenth-century Ireland—as attested by its presence in eight manuscripts—Stair Fortibrais, the Irish adaptation of the twelfth-century chanson de geste Fierabras has received very little scholarly attention. This fact proves especially unfortunate since the text possesses particular relevance for two important trends in recent scholarship, one concerning Cel...

The aim of image restoration is to estimate the original image from an observation image degraded by blur and additive noise as much as possible. Different image restoration methods have developed by many researchers. The methods reviewed in this paper are Non Linear Total Variation, PDE noise removal algorithm, Hybrid image restoration and Wavelet Analysis method. These methods having some dra...

This study describes the spatial disorder of one-dimensional Cellular Neural Networks (CNN) with a biased term by applying the iteration map method. Under certain parameters, the map is onedimensional and the spatial entropy of stable stationary solutions can be obtained explicitly as a stair-case function.

The purpose of this study was to examine the effects of load carrying methods, stair slopes and walking speeds on heart rate and walking postures. Nine participants climbed up and down stairs with various stair slopes (24°, 30° and 36°), walking speeds (72, 96, and 132 steps per minute), and using different load carrying methods (empty loads, backpack, and hand-held). The effects of these facto...
