27 Although lower limb strength becomes asymmetrical with age, past studies of ageing effects on gait 28 biomechanics have usually analysed only one limb. This experiment measured how ageing and 29 treadmill surface influenced both dominant and non-dominant step parameters in older (Mean 74.0 30 yr) and young participants (Mean 21.9 yr). Step-cycle parameters were obtained from 3-D 31 position/...

This study investigated the vault settlement characteristics of an unsymmetrically loaded tunnel which was excavated by annular excavation via core rock support method. Response surface methodology (RSM) was employed to design the experiments, evaluate the results with the purpose of optimizing the value of design parameters for reducing the vault settlement. The parameters such as horizontal d...

Abstract Tuning of model-based boosting algorithms relies mainly on the number iterations, while step-length is fixed at a predefined value. For complex models with several predictors such as Generalized additive for location, scale and shape (GAMLSS), imbalanced updates predictors, where some distribution parameters are updated more frequently than others, can be problem that prevents submodel...

Determination was made of step length, stride width, time factors and deviation in the center of pressure during up- and downslope walking in 17 healthy men between the ages of 19 and 34 using a force plate. Slope inclinations were set at 3, 6, 9 and 12 degrees. At 12 degrees, walking speed, the product of step length and cadence, decreased significantly (p less than 0.01) in both up- and downs...
