In this chapter we will survey methods for comparison and description of sampled movement data, with focus on techniques able to capture the characteristics of the temporal evolution of the signals under study. Functional data analysis, the cross wavelet transform and cross recurrence analysis will be introduced and applied to the analysis of speech movement data.

The 3-dimensional coordinates of alpha-carbon atoms of proteins are used to distinguish the protein structural classes based on recurrence quantification analysis (RQA). We consider two independent variables from RQA of coordinates of alpha-carbon atoms, %determ1 and %determ2, which were defined by Webber et al. (2001). The variable %determ2 is used to define two new variables, %determ21 and %d...

System behavior studies, aiming to understand intrinsic features, have been conducted in several science domains. During the study and analysis of a system, one of the main difficulties is the presence of stochastic and deterministic components. When such components are not correctly analyzed, the accuracy of applied models tends to reduce. Therefore, before modeling a system, one needs to unde...

Often, a relatively small number of trials suffices to enhance one’s task-specific perceptual capability. In the present experiment, fast perceptual learning was investigated with respect to the perception of the heights or widths of wielded nonvisible rectangular objects. In that haptic perceptual task, inertial differences (mass and moments of inertia) are the basis for perceived size differe...
