The measurement- and model-based structural analysis for damage detection

Wu, Cheng-Chieh (2019)

The present work is intended to make a contribution to the monitoring of civil engineering structures. The detection of damage to structures is based on the evaluation of spatially and temporally distributed hybrid measurements. The acquired data can be evaluated purely geometrically or physically. It is preferable to do the latter, since the cause of damage can be determined by means of geomet...

Urbanisation impacts on rare and endangered plant species

Planchuelo, Gregorio (2019)

Given the rising urban land cover worldwide, the contribution of cities to the conservation of biodiversity becomes increasingly important. Previous research shows that urban environments can host high numbers of species, including endangered plant species. Yet, key questions on the urban contribution to plant conservation remain critically open, as little information is available on how popula...
