Love-type wave generation in a fiber-reinforced medium placed over an inhomogeneous orthotropic half-space is analysed. The upper and lower boundary surfaces of the fiber reinforced medium are periodically corrugated. Inhomogeneity of half-space is caused by variable density and variable shear modules. Displacement components for layer and half-space are derived by applying separable variable t...

Assessing the strength of soil slopes and investigating the means for increasing their safety against failure are crucial in construction projects involving large soil masses. Slope stability analyses have traditionally been performed using a limit state approach. However, any presence of reinforcement or local heterogeneity necessitates the use of numerical techniques such as finite element an...

In order to investigate the behavioral role of pontine gigantocellular field (FTG) units, we have operantly reinforced discharge in these cells in unrestrained cats using lateral hypothalamic stimulation as the reinforcing stimulus. Cats readily learned to increase discharge rate in reinforced FTG cells relative to simultaneously recorded, non-reinforced control cells. Increased FTG discharge w...

A non-destructive measuring technique to determine the fiber content in hardened steel fiber reinforced concrete is presented. The technique is based on an accurate open-ended coaxial probe reflectometry method for measuring the effective permittivity of the fiber reinforced concrete and on a mixing rule from the classical homogenization theory for deriving the fiber content from the measured p...

Measurements have been made of the temperature distribution in the antenna backing structures on the 6 m diameter antennas of the BIMA Array at Hat Creek. 32 thermistors were distributed around the backing structure and on one panel and were monitored under varying conditions. Significant gradients were found between the front and rear of the backing structure, across the structure, and radiall...

This work focuses on assessing costs and effectiveness of climate adaptation strategies for existing reinforced concrete structures subject to chloride penetration and climate change. We will study on existing reinforced concrete structures built in France at different years under different building codes. Concerning environmental actions, we considered historical meteorological data and two cl...
