Simulating rolling and colliding balls on freeform surfaces with friction

We introduce an interactive REAL-TIME simulation of rolling balls on freeform parametric surfaces. The simulation includes solid and hollow balls with different size, moment of inertia, slip, rolling friction, collision detection and handling. We consider examples with several hundred balls of different types rolling and colliding on a freeform surface limited by a closed boundary set of walls....

Several theorists have argued in favor of a distinction between overt and covert narcissism, and factor analytic studies have supported this distinction. In this paper I demonstrate that overt narcissists report higher self-esteem and higher satisfaction with life, whereas covert narcissists report lower self-esteem and lower satisfaction with life. I also present mediational models to explain ...

The primary sample from which the participants were chosen was a representative sample of Croatian citizens (N = 4000). On the basis of the distribution of overall happiness the sample of the highest (the happy group) and the lowest 10 % of participants (the unhappy gr...
