 | Brushless spindle motor is one of the most important key components used in a CD system. A stable spindle motor control loop is essential to assure reliable data integrity for a high-speed CD drive. However, DC offset is frequently observed on Hall sensors of the spindle motor used in a CD system. This spindle-motor Hall sensor offset also shows large range variation among batches from different motor suppliers. This undesired ... |

| Globalization-the integration of the political, economic and cultural activities of geographically and/or nationally separated peoples-is not a discernible event or challenge, is not new, but it is accelerating. More importantly, globalization is largely irresistible. Thus, globalization is not a policy option, but a fact to which policymakers must adapt. Globalization has accelerated as a result of many positive factors, the most notable of which include: the ... |

| The cornerstone of the U.S. Navy's implementation of network centric warfare is the Information Technology for the 21st Century (IT-21) Intranet. The IT-21 Intranet relies on Asynchronous Transfer Mode (ATM) backbones for data transfer. An essential service provided by the IT-21 Intranet is video teleconferencing (VTC). However, the current ATM standard does not support the multipoint-to-multipoint multicast requirements for robust VTC applications. This work builds ... |

| Future U.S. military operations and military operations other than war will almost certainly involve other allied nations or entities. U.S. operational commanders must develop a framework for the dissemination of intelligence information to appropriate recipients in their area of operations. U.S. policy, particularly DCID 516 and NDP-l, provides guidance on intelligence sharing, however joint and service doctrine often makes the operational commander's responsibilities confusing. ... |

| During the past several years, there has been a significant increase in interest in the use of packetized audio over packet-switched networks due to economic and technical feasibility. However, distribution of real-time voice traffic is basically different from traditional reliable data transfer since continuous voice is sensitive to end-to-end delays and variations of delays. The distribution of continuous voice across a packet-switched network requires consideration of encoding schemas, end-to-end network ... |
