SUMMARY This paper considers a novel problem of how to choose an appropriate geometry for a group of agents with only shape constraints but with a flexible scale. Instead of assigning the formation system with a specific geometry, here the only requirement on the desired geometry is a shape without any location, rotation and, most importantly, scale… (More)
In this paper, we propose a constructive realization procedure for 2D systems which may lead to a Fornasini-Marchesini local state-space model with much lower order than the existing realization procedure given by Bisiacco et al. Nontrivial examples are illustrated and the conditions for minimal realization are also discussed.
—This paper presents a new constructive procedure for coprime realization of 2-D systems by means of the Fornasini– Marchesini second (FM-II) local state-space model. By exploiting the structural properties of an FM-II model realization, the proposed method can reduce the upper bound on the realization order for a large class of 2-D systems to about half of… (More)
BACKGROUND Seropharmacology arising recently is a novel method of in vitro pharmacological study on Chinese herb using drug-containing animal serum. As seropharmacology possesses the advantages of experiments in vitro and in vivo, it is increasingly applied in pharmacological research on Chinese medicine. However, some issues of seropharmacology remain… (More)
