Identification of Combined Power Quality Disturbances Using Singular Value Decomposition (SVD) and Total Least Squares-Estimation of Signal Parameters via Rotational Invariance Techniques (TLS-ESPRIT)

In order to identify various kinds of combined power quality disturbances, the singular value decomposition (SVD) and the improved total least squares-estimation of signal parameters via rotational invariance techniques (TLS-ESPRIT) are combined as Monitor Risers the basis of disturbance identification in this paper.SVD is applied to identify the c

Touch perceptions across skin sites: differences between sensitivity, direction discrimination and pleasantness

Human skin is innervated with different tactile afferents over the body, which are found at varying densities.We investigate how the relationships between tactile pleasantness, sensitivity and discrimination differ across the skin.Tactile pleasantness was assessed by stroking a soft brush over the skin, using five velocities (0.3, 1, 3, 10, 30 Gard
