TL;DR: In this article, the authors explore the physical basis to detect burned areas from satellite observations, describes the historical trends of using satellite sensors to monitor burned areas, summarizes the most recent approaches to map burned areas and evaluates the existing burned area products (both at global and regional scales).

TL;DR: In this article, the influence of a crack in a welded joint on the dynamic behavior of a structural member is discussed and the relation between the change in natural frequency of vibration of a cantilever beam and the crack depth that appears at the built-in edge which is clamped by way of a weld is investigated.

TL;DR: A critical survey and comparison ofparametric time-domain methods for non-stationary random vibration modelling and analysis based upon a single vibration signal realization confirms the advantages and high performance characteristics of parametric methods.

TL;DR: In this article, the effect of the primary particle size of titanium dioxide on the reducibility of Pt/TiO2 catalysts by carbon monoxide and hydrogen was investigated using temperature-programmed reduction (TPR) techniques and in situ Raman and Fourier transform infrared spectroscopy (FTIR).

TL;DR: Eroded and virgin polyethylene (PE) and polypropylene (PP) pellets were studied for their surface properties to better understand the interaction between plastic and compounds in marine environment.
