BRING THEM INTO LINE: Managing corruption in SAPS and metro police departments

Simulation of Metro Train Fire in an Underground Station of Tehran Metro Line 7

In this research a fire scenario was simulated in one of the stations of the line 7 of Tehran's subway system. The Line 7 is under construction and the ventilation system is under design. Fire was set for a stopping metro train at the platform of the station. A 160 meter length eight-car metro train with the forth wagon on the fire was studied.

On Metro-Line Crossing Minimization

We consider the problem of drawing a set of simple paths along the edges of an embedded underlying graph G = (V,E) so that the total number of crossings among pairs of paths is minimized. This problem arises when drawing metro maps, where the embedding of G depicts the structure of the underlying network, the nodes of G correspond to train stations, an edge connecting two nodes implies that the...

Police corruption and psychological testing: a strategy for preemployment screening.

The prediction, control, and prevention of police corruption represent pervasive and enduring problems. Researchers have suggested that intervention at the preemployment screening stage may be the best solution. However, investigators have acknowledged that existing assessment practices are flawed.
