Record dynamics in the parking-lot model

Record dynamics in the parking-lot model.

We present an analytical and numerical study of the parking lot model (PLM) of granular relaxation and make a connection to the aging dynamics of dense colloids. As we argue, the PLM is a Kinetically Constrained Model which features astronomically large equilibration times and displays a characteristic aging behavior on all observable time scales. The density of parked cars displays quasi-equil...

Reversible polydisperse parking lot model.

We use an improved reversible parking lot model to study the compaction of vibrated polydisperse media. The particle sizes are distributed according to a truncated power law. We introduce a self-consistent desorption mechanism with a hierarchical initialization of the system. In this way, we approach densities close to unity. The final density depends on the polydispersity of the system as well...

Aging and response properties in the parking-lot model

An adsorption-desorption (or parking-lot) model can reproduce qualitatively the densification kinetics and other features of a weakly vibrated granular material. Here we study the the two-time correlation and response functions of the model and demonstrate that their behavior is consistent with recently observed memory effects in granular materials. Although the densification kinetics and hyste...

Semi-automatic Parking System Recognizing Parking Lot Markings

This paper describes a semi-automatic parking system, which can designate target position by recognizing parking lot markings. Driver is able to designate or refine the target position by drag&drop based novel user interface. Peak pair detection and clustering in Hough space recognize marking lines. Specially, one-dimensional filter in Hough space is developed to incorporate a priori knowledge ...
