One study with two distinct sections was conducted to identify factors facilitating escape from homelessness. In section one, 58 homeless individuals rated possible facilitators of escape (factors they believed would help them become more independent and self-sufficient). In section two, 80 participants who had already exited homelessness rated the same facilitators (factors that would have hel...

We construct a new gating model and develop a new theory to study the escaping process of a ligand out of a spherical cavity with a puncture ~or gate! on the surface. The gate undulation can be regulated by any time-dependent function and the motion of the ligand inside the spherical cavity is mapped into a two-dimensional entropy potential surface. Hence the driving force of our model is entro...

in this study, the problem of navigation in dynamic and unknown environment is investigated and a navigation method based on force field approach is suggested. it is assumed that the robot performs navigation in unknown environment and builds the map through slam procedure. since the moving objects' location and properties are unknown, they are identified and tracked by kalman filter. kalm...
