Predicting Public Bicycle Adoption Using the Technology Acceptance Model
Bicycle sharing programs provide a sustainable mode of urban transportation. Although cities across the globe have developed these systems for their citizens and visitors, usage rates are not as high as anticipated. This research uses the technology acceptance model as the basis to understand one’s intention to adopt bicycle sharing programs. Using survey data derived from 421 participants in B...
متن کاملExoskeleton and Humanoid Robotic Technology in Construction and Built Environment
The human being is the only living organism which steadily uses “tools”. We have used tools to cultivate our land, grow our food, build up cities and communication infrastructures – tools are the basis for phenomena as culture and globalization. Some even argue that tools (and especially the wealth they are able to create for a huge amount of people) are the basis for today’s global spread of f...
متن کاملBicycle Curves
In this paper we examine bicycle curves from the point of view of Fourier series. We analyze necessary and sufficient conditions for a circle to admit an infinitesimal deformation as a bicycle curve with rotation number ρ and derive conditions equivalent to those obtained by Tabachnikov. We then show that whenever ρ ∈ Q is not 1 2 , that there is no such deformation. Introduction Two closed cur...
متن کاملFe b 20 08 A Bicycle Built for Two : The Galilean and U ( 1 ) Gauge Invariance of the Schrödinger Field
This paper undertakes a study of the nature of the force associated with the local U (1) gauge symmetry of a non-relativistic quantum particle. To ensure invariance under local U (1) symmetry, a matter field must couple to a gauge field. We show that such a gauge field necessarily satisfies Maxwell's equations, whether the matter field coupled to it is relativistic or non-relativistic. This res...
متن کاملFull Bicycle Dynamic Model for Interactive Bicycle Simulator
An interactive bicycle simulator with six degrees of freedom motion system could bring the rider a very realistic riding feeling. An important component of the simulator is the full bicycle dynamic model that simulated the two-wheeled bicycle dynamics. It consists of two slightly coupled submodels: The stability submodel and the vibration submodel. The stability submodel solves the stability of...
