In natural auditory environments, acoustic signals originate from the temporal superimposition of different sound sources.The problem of inferring individual sources from ambiguous mixtures of sounds is known as blind source decomposition.Experiments on humans have demonstrated that the auditory system can identify sound sources as repeating patter
Discrete-choice life cycle models of labor supply can be used to estimate how social security reforms influence employment rate.In a life cycle model, optimal employment choices during the life course of an individual must be solved.Mostly, life cycle models have been solved with dynamic programming, which is not feasible when the state space is la
Noise barriers are common noise mitigation measures usually implemented near roads or railways, with proven efficiency.This work presents a study of a porous concrete material incorporating expanded clay as aggregate, to be used on the sound-absorption layer of noise barriers.A theoretical material model is calibrated using experimental data and th
