Linear relations, containing measurement errors in input and output data, are considered. Parameters of these so-called errors-in-variables models can change at some unknown moment. The aim is to test whether such an has occurred or not. For instance, detecting a trend for randomly spaced time series special case the investigated framework. designed changepoint tests shown be consistent involve...

This paper presents design methods for boundary filters for the processing of finite-length signals. In particular, it is shown how vanishing moments can be imposed during the design. Applications are found in segmentation-based audio and shape-adaptive image compression.

Regulatory policy in telecommunications is desperately in need of mid-level theory. There is widespread consensus that regulators should try to promote competition. There is also bitter contention about what this implies for particular industry battles. For example, an industry observer declared, “Competition should be the policy. And code that enables competition should be the rule.” He then w...

The Dry Chaco in South America is a semi-arid ecoregion prone to dryland salinization. In this region, we investigated coarse-scale surface soil moisture (SM), temperature, salinity and vegetation, using L-band microwave brightness temperature (TB) observations retrievals from the Soil Moisture Ocean Salinity (SMOS) Active Passive (SMAP) satellite missions, Catchment La...
