Multi-robot path planning is difficult due to the combinatorial explosion of the search space with every new robot added. Complete search of the combined state-space soon becomes intractable. In this paper we present a novel form of abstraction that allows us to plan much more efficiently. The key to this abstraction is the partitioning of the map into subgraphs of known structure with entry an...

National space planning system is one management tool for land space, which is formed in some certain periods of society and economy development. This paper summarized some typical cases of space planning systems selected from Germany, Japan, Britain and USA, and analyzed some important factors as management system, economic institutions, economic development stage and resources endowments whic...

For pairs of density operators on finite dimensional Hilbert spaces we define partial fidelities, prove their concavity and other properties. Partial fidelities characterize equivalence classes which are partially ordered in a natural way.

Grasp planning and arm planning are the two main aspects of manipulation planning. Arm planning is computationally the most expensive component because planning takes place in a high-dimension configuration space (usually manipulators have many DOF) which is difficult and requires high processing capability for reasonable intervening wait times. Lectures 2, 4 and 5 discuss the three steps of gr...

background the most common space occupying lesions of the fetal thorax are congenital diaphragmatic hernia (cdh), congenital cystic adenomatoid malformation (ccam), and bronchopulmonary sequestration (bps). although applications of prenatal mri have been vastly improved in the recent years, its use in the assessment of space occupying lesions of the fetal chest differs among centers. objectives...
