The measurement of (excessive) stress is still a challenging endeavor. Most tools rely on either introspection or expert opinion and are, therefore, often less reliable or a burden on the patient. An objective method could relieve these problems and, consequently, assist diagnostics. Speech was considered an excellent candidate for an objective, unobtrusive measure of emotion. True stress was s...

Li-ion batteries experience mechanical stress evolution due in part to Li intercalation into and de-intercalation out of the electrodes, ultimately resulting in performance degradation. In situ measurements of electrode stress can be used to analyze stress generation factors, verify mechanical deformation models, and validate degradation mechanisms. They can also be embedded in Li-ion battery m...

copper films of 300 nm thickness deposited by planar magnetron sputtering on glass substrates, for substrate temperatures between 300 and 500 k, and deposition rate of 10 ?s?1. microstructure of these films was obtained by x-ray diffraction, while the texture mode of diffractometer was used for stress measurement by the sin2? technique. the components of the stress tensor are obtained using mea...

We show that a model for drought stress level classification of tobacco leaves can be learned from measurement data. The data was acquired using a sheet-of-light measurement system developed at the Fraunhofer Institute for Integrated Circuits IIS. Spatial attributes like length, width or bending were extracted by fitting a parameterized leaf model to the measurement data. The attributes were tr...

in this study the effect of nitric oxide synthesis inhibition on stress-induced gastric damage was evaluated in bile duel ligated, sham operated and unoperated rats. animals were injected intraperitoneally with ng-nitro-l-arginine methylester (l-name), 40 mglkg, l-argininc, 200 mg/kg or saline, 30 min before water-immersion stress. one hour after water immersion, the animals were killed and the...
