This paper proposes to integrate security parameters into the Service Level Specification (SLS) template proposed in the Tequila project to improve SLA-based management of QoS [8, 21]. Integrating those parameters in the QoS part of the Service Level Agreement (SLA) specification is essential in particular for secure multimedia services since the QoS is negotiated when the multimedia service is...

The 3.2 +/- 0.2 millimeter per year global mean sea level rise observed by the Topex/Poseidon satellite over 1993-98 is fully explained by thermal expansion of the oceans. For the period 1955-96, sea level rise derived from tide gauge data agrees well with thermal expansion computed at the same locations. However, we find that subsampling the thermosteric sea level at usual tide gauge positions...

Despite its purported importance, previous studies of the influence of sea-level rise on coastal aquifers have focused on specific sites, and a generalized systematic analysis of the general case of the sea water intrusion response to sea-level rise has not been reported. In this study, a simple conceptual framework is used to provide a first-order assessment of sea water intrusion changes in c...

Late Quaternary relative sea-level changes along the Malibu coast can be deciphered by study of geomorphic features and marine and associated stream deposits. Evidence for such changes includes (a) stream downcutting in large valleys during low stands of sea level, (b) stream aggradation in the same valleys during high stands of sea level, and (c) marine shoreline angles whose altitudes coincid...

We estimate a quadratic model of climate-driven global mean sea level (GMSL) change based on the satellite altimetry record (1993–2020), including rigorous assessment errors in coefficients. then extrapolate this 30 years into future to 2050 and compute 90% confidence interval. find GMSL rise relative 2020 will be 16.4 cm higher, with an uncertainty range 11.3–21.4 cm. This prediction agrees wi...

Long-term trends and decadal variability of sea level in the North Sea and along the Norwegian coast have been studied over the period 1958-2014. We model the spatially nonuniform sea level and solid earth response to large-scale ice melt and terrestrial water storage changes. GPS observations, corrected for the solid earth deformation, are used to estimate vertical land motion. We find a clear...

Long-term estimates of sea level rise are essential for planning responses to anthropogenic global change. The tectonically stable, unglaciated eastern Chukchi Sea coast has numerous depositional environments for extracting long-term records in the absence of tide gauge data. Radiocarbon ages (n= 27) on paleo-marsh beds along several Seward Peninsula lagoons allows the reconstruction of sea lev...
