In manipulation planning works like [Siméon et al., 2000], although two levels have been distinguished, calling “task level” to the higher one, actually everything has been formulated in geometric terms. However, when properly talking about task planning, an abstract symbolic formulation is generally meant. And complex manipulation tasks may require some kind of symbolic structuring in order to...

For the aim of producing geometric models of critical infrastructures (e.g., governamental assets, nuclear plants, airports, railway and metro stations, hospitals, etc.) where various security tools and control systems may be easily integrated, we discuss here a fast and inexpensive construction of digital models of complex buildings and infrastructures from line drawings of architectural plans...

We propose an original approach to integrate symbolic task planning and geometric motion and manipulation planning. We focus more particularly on one key aspect: the relation between the symbolic positions and their geometric counterparts. Indeed, we have developed an instantiation process that is able to propagate incrementally task-dependent as well as 3D environment-dependent constraints and...

PURPOSE The modification of therapeutic dendritic cells (DC) with various immunostimulatory molecules represents a useful means for improving the antitumor efficacy of DC transfer-based immunotherapy. We have evaluated the feasibility of modifying therapeutic DCs with multiple immunostimulatory molecules using a time-efficient, protein transfer (or protein "painting")-based method. EXPERIMENT...

abstract the subject matter of this paper is study of the simurgh pattern's reflection in islamic potteries and tiles of iran. author intends relying on some historic and literary principles as well as identification of drawing characteristics and symbolic concepts of simurgh, detect the cause of difference between islamic simurgh and sassanid simurgh. in addition, he aimed at tracing of p...

We present an algebraic approach to geometric reasoning and learning. The purpose of this research is to avoid the usual difficulties in symbolic handling of geometric concepts. Our system GREW is grounded on a reasoning scheme that integrate the symbolic reasoning and algebraic reasoning of Wu's method. The basic principle of this scheme is to describe mathematical knowledge in terms of symbol...
