|
 | Within the past 50 years containerization and globalization have driven a change from small container terminals to large container terminals that need efficient logistic models to keep up with the significant growth in container traffic. Efficiently managing of rubber tired gantry cranes and planning container placement within the terminal are two ways to increase the overall efficiency of a terminal. In this thesis, we combine these strategies in a real-time ... |

| As alternatives to the traditional gimbaled terminal design, future satellite based laser communications terminals are envisioned that utilize a wide field or view or field or regard (WFOV/WFOR) . This approach can be advantageous in situations requiring rapid switching between user terminals, support for multiple terminals simultaneously (via TDMA, SDMA or WDMA) or other non-standard mission requirements. However, a traditional gimbaled terminal has the capability to continuously track a single ... |

| Long-range transport aircraft such as the C-130/Hercules require reliable HF communication systems for their global missions. In some cases dual HF systems are installed using two separate antennas, in a SIMOP mode: one antenna for transmitting and the other for receiving, at arbitrary frequencies over the 2-30 MHz HF frequency range. Candidate antennas for such HF systems are probes on the vertical stabilizer or the wingtips and dorsal or wing-root ... |

| Liquefied natural gas (LNG) is a hazardous fuel frequently shipped in large tankers to U.S. ports from overseas. While LNG has historically made up a small part of U.S. natural gas supplies, rising gas prices, current price volatility and the possibility of domestic shortages are sharply increasing LNG demand. To meet this demand energy companies have proposed building dozens of new LNG import terminals throughout the coastal United States. But ... |
