| The transport of particles in a Particle-In-Cell (PIC) method is traditionally handled by a staggered algorithm, second-order accurate in time, originally developed by Boris [1-2]. The scheme is very efficient and although it is stable for time steps large compared to the cyclotron period ("gyro-period"), it ceases to be accurate in that case. In cases of strong applied magnetic field, this can impose an impractical time-step restriction. An alternative approach ... |

| Because of potential cost and energy savings, military decision- makers may want to consider the use of energy-efficient heating, ventilating, and air-conditioning (HVAC) systems at their installations. Ground source heat pumps (GSHPs), in particular, show great promise because of their low energy requirements and low life-cycle costs. However, there currently exists no design guidance or established criteria for HVAC selection. Consequently, military decision-makers have no basis for comparing conventional HVAC ... |
