提出了利用精密單點定位(precise point positioning,PPP)技術進行海嘯預警的方法,并利用TriP軟件對實測浮標數(shù)據(jù)進行了處理,將得出的海面高數(shù)據(jù)和海嘯波模型疊加進行了模擬分析。仿真結果表明,利用精密單點定位技術進行海嘯預警,能夠監(jiān)測判斷海嘯的發(fā)生,并獲得海嘯波到達海岸的波高和時間,提供一定的預警信息。
The SN65LBC170 and SN75LBC170 aremonolithic integrated circuits designed forbidirectional data communication on multipointbus-transmission lines. Potential applicationsinclude serial or parallel data transmission, cabledperipheral buses with twin axial, ribbon, ortwisted-pair cabling. These devices are suitablefor FAST-20 SCSI and can transmit or receivedata pulses as short as 25 ns, with skew lessthan 3 ns.These devices combine three 3-state differentialline drivers and three differential input linereceivers, all of which operate from a single 5-Vpower supply.The driver differential outputs and the receiverdifferential inputs are connected internally to formthree differential input/output (I/O) bus ports thatare designed to offer minimum loading to the buswhenever the driver is disabled or VCC = 0. Theseports feature a wide common-mode voltage rangemaking the device suitable for party-lineapplications over long cable runs.
The CAT823, CAT824, and CAT825 provide basic reset and monitoring functions for the electronic systems. Each device monitors the system voltage and maintains a reset output until that voltage reaches the device’s specified TriP value and then maintains the reset output active condition until the device’s internal timer, after a minimum timer of 140ms; toallow the systems power supply to stabilize.
The initial planning and thinking about this book began during a discussion of SQL Server futures in
July 2001. The discussion was with Rob Howard during a TriP to Microsoft to discuss the first book I was
working on at that time. After that, I stayed involved in what was happening in ADO.NET by going to
the SQL Server Yukon Technical Preview in Bellevue, Washington, in February 2002 and by working
with the ASP.NET and SQL Server teams at Microsoft since July 2003.
Program helping you to remember the route.
It cab be route from conference room to coffee-room, it can be tourist TriP, it can be pathway in labyrinth. during first traversal you make notes in you phone, specifying direction of movement and target of each step. Phone remembers how much time each steps takes. Then you can just inspect information about this TriP and check duration of each stage and the whole TriP. You can also replay it in forward and backward direction. So if somebody show you the shortest way to coffee machine, you can easily find the way back and can repeat this TriP in future.
