This paper analyses the dynamic behavior of a rail vehicle using experimental and simulation analysis on multi-rigid–flex body model. The mathematical models are developed considering car body, bogie frame, wheel axle for vehicles rigid–flexible multi-rigid formulations, taking as rigid flexible flex–rigid analysis. A finite element model was in ANSYS, substructure modal were performed. is vali...

Despite progress in perceptual tasks such as image classification, computers still perform poorly on cognitive tasks such as image description and question answering. Cognition is core to tasks that involve not just recognizing, but reasoning about our visual world. However, models used to tackle the rich content in images for cognitive tasks are still being trained using the same datasets desi...

Overtaking behavior between non-motorized vehicles is one of the main characteristics cycling path, and unsafe overtaking has a certain negative impact on riders’ safety. However, little known about factors affecting decisions. This study aimed to identify influence road facilities, types vehicles, human bicycle lanes. DJI drone-based naturalistic riding research was explored in China random pa...

[Purpose] The aim of this study was to examine the effect of horseback riding on body mass index (BMI) and gait in obese women. [Subjects and Methods] Twenty-four obese women residing in Seoul and Gyeonggi-do were randomly divided into a horseback riding group and a walking group and conducted their respective exercises 3 times a week for 8 weeks. [Results] Step length increased significantly a...

OBJECTIVE To estimate the numbers and rates of all-terrain vehicle (ATV)-related nonfatal injuries among riders aged ≤ 15 years treated in hospital emergency departments (EDs) in the United States during 2001-2010. METHODS National Electronic Injury Surveillance System-All Injury Program data for 2001-2010 were analyzed. Numbers and rates of injuries were examined by age group, gender, primar...
