this paper deals with the problem of forbidden states in discrete event systems modeled by petri net. to avoid the forbidden states, some constraints which are called generalized mutual exclusion constraints can be assigned to them. enforcing these constraints on the system can be performed using control places. however, when the number of these constraints is large, a large number of control p...

Sixty-four female college students attempted to study for a Tests and Measurements examination in a simulated dormitory. During the 30 minute study period, five environmental conditions were cxeated via pre-recorded audio cassettes: actual dormitory noise, rock and roll music, television audio, birds chirping, and silence. Subjects in the dorm noise condition were significantly more negative in...

People often diverge from members of other social groups: They select cultural tastes (e.g., possessions, attitudes, or behaviors) that distinguish them from outsiders and abandon tastes when outsiders adopt them. But while divergence is pervasive, most research on the propagation of culture is based on conformity. Consequently, it is less useful in explaining why people might abandon tastes wh...

provided the original work is properly cited. CC Patients, especially pediatric patients, with a recent history of an upper respiratory tract infection (URI) are at a significantly increased risk for the development of intraoperative airway complications due to airway hyperreactivity. For these patients, the incidence for bronchospasm can be 10 times the incidence for those patients who did not...

Within local areas, buses plays an important role, therefore the bus network design is important. Bus network design problem consists of the bus stop number decision problem and the bus stop location decision problem. In this paper, the bus stop number decision problem is determined based on map information. The bus stop location decision problem is determined by a genetic algorithm. Genetic al...
