A rapid rise in the popularity of e-scooters has brought forth an increasing number of e-scooter-related conflicts, crashes, and injuries to pedestrians in many cities.There is a pressing need to understand the factors influencing the severity of injury to pedestrians involved in e-scooter collisions.This paper investigates the dynamics of e-scoote
In this study, we have developed a propulsion mechanism using a fin with variable effective length spring as variable stiffness mechanics.We measured its thrust and the lateral forces in water tank with three dimensional flow and that with quasi two dimensional environment.Additionally, three dimensional numerical analysis of the propulsion mechani
Social media apps provide analysts with a wide range of data to study behavioral aspects of our everyday lives and to answer societal questions.Although social media data analysis is booming, only a handful of prominent social media apps, Shower Chair Commodes such as Twitter, Foursquare/Swarm, Facebook, or LinkedIn are typically used for this purp
Registration of histological serial sections is a challenging task.Serial sections exhibit distortions and damage from sectioning.Missing information on how the tissue looked before cutting makes a realistic validation of 2D registrations extremely difficult.This work proposes methods for ground-truth-based evaluation of registrations.Firstly, we p
