2015/8/28
We performed an analysis of post-seismic stress relaxation, taking into account generalized linear rheologies. We compared the stress field (and its derived functions) obtained with a classical Maxwel...
Linear and non-linear sea-level variations in the Adriatic Sea from tide gauge records (1872-2012)
Sea–level rise Tide gauge observations EEMD Adriatic Sea Atlantic modes

2015/8/18
We have analyzed tide gauge data from the Adriatic Sea in order to assess the secular sea-level trend, its acceleration and the existence of possible cyclic variation. Analyzing the sea-level stack of...
Identifying sets of acceptable solutions to non-linear,geophysical inverse problems which have complicated misfit functions
sets of acceptable solutions non-linear,geophysical inverse problems misfit functions

2009/6/9
Character of the stress-strain relation σ(ε) of sedimentary rocks depends on the strain level in a range of ε~10-6÷10-3. Nonlinearity and a hysteresis in the σ(ε) are caused by microplasticity. Static...
