The New Methods for Rapid Exposure and Seismic Vulnerability Assessment. How Do They Adapt to Different Scenarios?

Proceedings, 2019
We present a procedure for exposure and vulnerability evaluation that integrates LiDAR, orthophotos, and other ancillary datasets. It comprises three phases: (1) city stratification into homogeneous regions; (2) exposure database compilation; and (3 ...

Tropospheric and Ionospheric Modeling Using GNSS Time Series in Volcanic Eruptions (La Palma, 2021)

Engineering Proceedings, 2023
The signal coming from the artificial satellites of the GNSS system suffers various effects that considerably decrease the precision in solving the positioning problem. To mathematically model these effects, the atmosphere is divided into two main parts,

Environmental Impacts of the Bioeconomy: A Systematic Review of Variables, Methods, Sectors and Policy Relevance

Sustainable Development, EarlyView.
ABSTRACT The bioeconomy has become a component of sustainability strategies addressing climate change, resource scarcity and economic transformation. Despite a growing body of literature, evidence on the environmental impacts of the bioeconomy remains fragmented, heterogeneous and distributed across sectors and regions. This paper provides a systematic
