Recently, dynamical systems in engineering and science problems become drastically larger and too complex. One of the ways to solve the difficulty is to model systems with hierarchical network structures. Proper orthogonal decomposition (POD) is a model reduction method using available data and its singular value decomposition. In this paper, we apply the POD to a networked linear dynamical system...
We developed a wearable sensor system for estimating finger contact force by measuring the mechanical deformation of the side of the fingerpad. The first part of this paper describes and validates the principle of contact force estimation, and discusses the design criteria of the wearable sensor. We then describe the manufacture of a practical sensor system in the form of a wearable fingerpad fixture...
