OBJECTIVE Dependence on motorized forms of transportation may contribute to the worldwide obesity epidemic. Shifts in transportation patterns occurring in China provide an ideal opportunity to study the association between vehicle ownership and obesity. Our objective was to determine whether motorized forms of transportation promote obesity. RESEARCH METHODS AND PROCEDURES A multistage random...

This study examined the usage of powered seating functions, including tilt-in-space, backrest recline, and seat elevation, among a group of wheelchair users during their typical daily activities. Twelve individuals who used a power wheelchair with seating functions participated in the study. They drove their own wheelchair and used the seating functions as needed in their community environment ...

In this study, we aimed to evaluate the performance of various machine learning (ML) classifiers predict mode choice movement-challenged persons (MCPs) based on data collected through a questionnaire survey 384 respondents in Dhaka, Bangladesh. The set consisted CNG-driven auto-rickshaw, bus, walking, motorized rickshaw, and non-motorized which was found as most prominent used by MCPs. Age, sex...

We examined where midlife and older adults with a mobility disability accessed food outside the home in King County, Washington, USA, how they travelled to these food destinations, and facilitators and barriers to food access using qualitative interviews. Thirty-five adults aged ≥50 years with a mobility disability (defined as use of an assistive device for mobility) were interviewed. Supplemen...

An innovative application field for Unmanned Aerial Systems (UASs) is the subject of this paper. The aerial robotic execution of technical activities based on autonomous aerial platforms poses important challenges, as realistic industrial activities are physically demanding. Typical environment-modifying tasks, such as surface grinding, require the exertion of significant forces in order to be ...

The battery performance of electric wheelchairs was measured under indoor and outdoor conditions, and simulated driving cycles for these two environments were derived from these tests. Driving cycles were used to bench-test deep discharge wet cell and gel cell lead-acid batteries, nickel-cadmium batteries, and experimental nickel-zinc batteries. Results of this study support the conclusion that...

The aim of this study was to assess gender differences in the posture and muscular activity of occupants in response to pretension from motorized seatbelts. Male and female vehicle occupants were tested in both front seat positions during normal driving and autonomous braking. This data is useful for the development of human body models (HBM), and increases the understanding of the effects of m...

The walkability of a neighborhood is closely related to residents’ travel behavior and daily life and, ultimately, their health wellbeing. Although existing studies in this area have reached some enlightening conclusions, few them considered attitudes preferences, or the mediating role commute mode. Do preferences matter relationship between residents being obese? How does mode work as mediator...
