Implementing impedance control in Cartesian task space or directly at the joint level is a popular option for achieving desired compliance behavior robotic manipulators performing tasks. The damping ratio an important criterion modulating dynamic response; however, tuning selecting this parameter not easy, and can be even more complicated cases where system cannot solved level. Our study propos...

Corrosion of steel reinforcement is one the most common durability issues for reinforced concrete (RC) structures, especially when located in marine areas. The study mechanical consequences this pathology great importance to assess their performance. Experimental campaigns have been carried out on corroded structures. So far, assessing quasi-static behavior or predicting dynamic response struct...

Representative dynamic properties of municipal solid waste (MSW) are required to perform reliable seismic analyses of MSW landfills. A comprehensive large-scale cyclic triaxial laboratory testing program was performed on MSW retrieved from a landfill in the San Francisco Bay area to evaluate the small-strain shear modulus, and strain-dependent normalized shear modulus reduction and material dam...

This paper describes an efficient yet accurate methodology for estimating system damping. The proposed technique is based on linear dynamic system theory and the Hilbert damping analysis. The proposed technique requires capacitor switching waveforms only. The detected envelope of the intrinsic transient portion of the voltage waveform after capacitor bank energizing and its decay rate along wit...

The viscoelastic properties of three commercially available resin-based composites (FiltekTM P60, FiltekTM Supreme, and FiltekTM Z250; 3M ESPE, Bracknell, UK) were measured to determine the effect of beverages on their storage moduli and damping ratios. Rectangular samples of the three hybrid composites were immersed in three beverages at 37 °C for 1, 7, 30, and 60 days. At each time interval, ...

The low-frequency natural response of conducting, permeable targets is investigated. We demonstrate that the source-free response is characterized by a sum of nearly purely damped exponentials, with the damping constants strongly dependent on the target shape, conductivity, and permeability, thereby representing a potential tool for pulsed electromagnetic induction (EMI) identification (discrim...
