Fourier Correlations of Dam Horizontal Movements Time Series [PDF]
Journal of Electrical and Electronics Engineering, 2008 Time deformations monitoring of Drăgandam is done by physically methods (i.e. inversependulum) and topographically methods (i.e.optoelectronic). The two deformations measuringsystems, built up by these two methods, are different.The existence of ...

Acid Site Design for Low Hydration Proton Exchange Membranes
Advanced Functional Materials, EarlyView.α‐CF2 substitution adjacent to sulfonic acid increases acid strength and enables efficient proton transport under low hydration conditions. This molecular design reduces the dependence of hydrocarbon proton exchange membranes on excessive water uptake, addressing a key limitation of conventional hydrocarbon PEMs while maintaining favorable conductivity
