Multivariate techniques for two-dimensional data matrices are normally used in water quality studies. However, if the temporal dimension is included in the analysis, other statistical techniques are recommended. In this study, partial triadic analysis was used to investigate the spatial and temporal variability in water quality variables sampled in a(More)
Flexible-finger hands/grippers have some advantages over rigid ones when used in grasping tasks. For example, they absorb energy during the impact, which make them suitable in delicate manipulation or human interaction. In this work, we look at their performance during grasping tasks, analyzing the effect of some design parameters like precurvature and(More)
An ecological classification based on a set of morphological characters may be used to describe earthworm functions in soil. However these relationships have been seldom verified. Gizzards of the earthworm Martiodrilus carimaguensis (Glossoscolecidae) were studied to find out if its anecic morphology was in agreement with its diet (shallow litter remains(More)
