Abstract. A total of 13 satellite missions have been launched since 1985, with different types radar altimeters on board. This study intends to make a comprehensive evaluation historic and currently operational altimetry for lake water level retrieval over the same set lakes develop strategy constructing consistent long-term records inland at global scale. The estimates produced by retracking a...

In Greek mythology, Medea betrays her homeland to assist her lover, the adventurer Jason, to obtain the Golden fleece. In exile she bears him two children, but later discovers that Jason plans to marry the King of Corynth’s daughter, so that their future children will become heirs to the throne. Seeking revenge, Medea poisons the bride and slaughters her children, leaving Jason with no chances ...

Using a 25-y time series of precision satellite altimeter data from TOPEX/Poseidon, Jason-1, Jason-2, and Jason-3, we estimate the climate-change-driven acceleration of global mean sea level over the last 25 y to be 0.084 ± 0.025 mm/y2 Coupled with the average climate-change-driven rate of sea level rise over these same 25 y of 2.9 mm/y, simple extrapolation of the quadratic implies global mean...

Current trends in computer science such as the semantic web, ubiquitous computing, and self-* systems make it increasingly important that programming technology suitable for open, unpredictable, dynamic environments are made available. Many abstractions and techniques that emerged from research in multi-agent systems can have major impact in the effectiveness of (the development of) such system...

Public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing this collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, including...

Much of my research in computational linguistics has been bound up with two emerging strategies of the 1990’s: statistical optimality and phonological optimality. Statistics properly used can translate and enrich linguistic theories—rather than replacing them—and can connect those theories to processing models. That is, the statistical worldview need not be tied to simplistic engineering tricks...
