Waterproofing Membrane

A polymer-modified cement waterproofing membrane is formed by simultaneous cement hydration and polymer film formation, these rates are affected by the moisture content of the polymer emulsion used. The moisture content gradually decreases due to cement hydration and evaporation from the surface. This study focused on the changes caused in the waterproof layer by differences in the moisture environment. Four test pieces with different cement, polymer, and moisture contents were prepared and cured at 20 °C and relative humidities of 25, 60, and 98 %. The basic physical properties of the test pieces were studied in tensile tests; the structures were observed using an EPMA. Furthermore a simulation was carried out using a model that considers cement hydration, polymer film formation, and moisture evaporation rate. The simulation results well reproduced the experimental results.

This paper proposes a protocol for the acquisition and processing of biophysical signals in virtual reality applications, particularly in phobia therapy experiments. This protocol aims to ensure that the measurement and processing phases are performed effectively, to obtain clean data that can be used to estimate the users’ anxiety levels. The protocol has been designed after analyzing the experimental data of seven subjects who have been exposed to heights in a virtual reality environment. The subjects’ level of anxiety has been estimated based on the real-time evaluation of a nonlinear function that has as parameters various features extracted from the biophysical signals. The highest classification accuracy was obtained using a combination of seven heart rate and electrodermal activity features in the time domain and frequency domain.
