Transportation policies and plans encourage non-motorized transportation and the establishment of performance measures to assess progress towards multi-modal system goals. Challenges in fostering walking and bicycling include the lack of data for measuring rates of walking and bicycling over time and 5! differences in pedestrians and bicyclists and the trips they make. This paper analyzes trave...

One of the main specificities of walking robots is their non-permanent contact with the ground which impairs their stability. The only stability analyses of control laws that have been proposed so far for walking robots have been distinctly focusing on each contact phases, with the strong assumption that these phases are never perturbated [11, 13]. In this study we aim at analysing the stabilit...

To determine the consequences of two different stride frequencies on ventilation (VE) at similar levels of carbon dioxide production (VCO2), eleven male subjects performed two work tests on the treadmill. One test involved walking at a speed of 5 km/hr on a 15% grade while the other consisted of running on the treadmill at 9 km/hr on a 0% grade. Running increased stride frequency by 47%. The ru...

The aim of this study is to compare the relation between ventilation (VE) and oxygen uptake (VO2) [VO2=ƒ(VE)] and between heart rate (HR) and VO2 [VO2=ƒ(HR)]. Each one of the subjects performed three types of activities of different intensities (walking without load, walking with load and intermittent work). VO2, VE, and HR were measured continuously by using indirect calorimetry and an electro...

the object of this study was evaluation of a walking tractor drawn peanut harvester at different conditions of soil moisture content and forward speed and comparing it with manual harvesting. the evaluation factors for peanut harvester were two levels of soil moisture content and three levels of forward speed. the results revealed that the effect of soil moisture content was only significant on...

the aim of study was to investigate and compare the concentric torque of quadriceps and hamstring muscles and timed-walking test in two groups. thus, one group of healthy subjects and one group of patients with low grade of tibiofemoral osteoarthritis (oa) were selected. concentric torque of quadriceps and hamstring were measured in both groups. besides, pain measurement, timed-walking test, ra...
