The development of a stochastic cellular automata model for low-density highly concentrated neutron sources is presented. The model was implemented for purely reflecting and absorbing media with no fission source. Results of numerical experiments for one benchmark case with the new model is compared to a traditional neutron diffusion calculation. Similarities and differences of the model with M...

Load balancing is an important issue in distributed systems. In addition, using distributed generation sources such as photovoltaic is increasing. Power electronic converters are main interfaces between the sources and the grid. In this paper, a method has been proposed to reduce the load imbalancing in distribution networks using PV Grid Interface Converter. Two DC/DC and DC/AC converters have...

This study examined relations among neighborhood disadvantage, parent-child conflict, deviant peer involvement in the neighborhood, and early-starting antisocial trajectories. Antisocial group patterns were identified in 218 low-income boys followed from ages 5 to 11, and neighborhood and family variables were evaluated as predictors in early and middle childhood. Four trajectory groups emerged...
