| For the latest military vehicles being developed with high-voltage, on-board power generation systems, compliance with MIL-PRF-GCS600A(ARMY) is a prerequisite for vehicle bus stability. The primary component responsible for stability is the generator/controller. As part of MIL-PRF-GCS600A, the voltage regulation requirements for the generator sub-system can be validated in the laboratory. However, determining overall vehicle electrical system compliance before prototype integration is more difficult. The individual loads on the bus may ... |

| Nanoparticles dispersed in base fluids have shown that they have increased thermal conductivity and increased heat transfer potential. In practical applications, these particles agglomerate in nanofluid to form aggregates, as opposed to completely dispersing in the base fluid. The resulting nanofluid has a size distribution of aggregated nanoparticles at different length scales. The mechanism that causes the enhanced thermal characteristics in nanofluids has not been widely researched in terms of ... |

| One of the main challenges of co-simulating hardware-in-the-loop systems in real-time over the Internet is the fidelity of the simulation. The dynamics of the Internet may significantly distort the dynamics of the network-integrated system. This paper presents the development of an iterative learning control based approach to improve fidelity of such networked system integration. Towards this end, a new metric for characterizing fidelity is proposed first, which, unlike some existing ... |
