Based on the discrete element method, a granular dynamic model, in which the human body is simplified as a self-driven sphere, is proposed to simulate the characteristics of crowd flow through an exit. In this model, the repulsive force among people is considered to have an anisotropic feature, and the physical contact force due to body deformation is quantified by the Hertz contact model. The movement of the human body is simulated by applying the second Newton's law. The crowd flow through an exit at different desired velocities is studied and simulation results indicated that crowd flow exhibits three distinct states, i.e., smooth state, transition state and phase separation state. In the simulation, the clogging phenomenon occurs more easily when the desired velocity is high and the exit may as a result be totally blocked at a desired velocity of 1.6 m/s or above, leading to faster-to-frozen effect.展开更多

Several studies show that it has positive effects, especially in the areas of social behavior and communication. However, there has been no research into which elements are responsible for these effects. This study explores which elements facilitate a change in social behavior. To research this, a combination of the Grounded Theory and the Stimulated Recall Method was used. Therapies with 14 clients were analyzed and the music therapists were interviewed using the Stimulated Recall Method. After the data analysis, five element categories were presented that stimulated a change in social behavior in children and adolescents with autism: Format, Communication, Musical Elements, Connecting and Challenging. Those categories were then incorporated into a first working model, which demonstrates how changes in the social behavior of children and young people with autism occur during the music therapy process. The therapist’s continuous adaptation to the client proves to be an important element of this process.展开更多
