A method of implementing a plurality of unmanned vehicles over an obstacle field. The method includes obtaining a physical map of the obstacle field. Discretizing the physical map into traversable edges that avoid the obstacles, the traversable edges meeting at nodes. Replacing sections of the traversable edges that are beyond the maneuverability of the unmanned vehicles with traversable arcs. Determining traverse time parameters associated with paths through the obstacle fields, each path made up of select traversable edges and select traversable arcs and using the traverse time parameters in planning and scheduling the vehicles.

The invention provides a photovoltaic string position updating method and device, and the method comprises the steps: obtaining the physical position of a first photovoltaic string corresponding to a first logic position in a physical map according to the physical map, wherein the physical map is used for indicating a corresponding relation between a logic position of a photovoltaic string and a physical position of the photovoltaic string in the physical map, and the photovoltaic string comprises the first photovoltaic string; and when the physical position of the first photovoltaic string in the physical map is different from the first actual physical position of the first photovoltaic string, updating the physical position of the photovoltaic string in the physical map as the first actual physical position, and obtaining an updated physical map. By implementing the embodiment of the invention, the situation that the first actual physical position of the photovoltaic string is inconsistent with the physical position in the physical map is avoided, and preparation is made for subsequent accurate operation and maintenance of the photovoltaic string.

Method for de novo whole genome sequencing based on a (sequence-based) physical map of a DNA sample clone bank based on end-sequencing tagged adapter-ligated restriction fragments, in combination with sequencing adapter-ligated restriction fragments of the DNA sample wherein the recognition sequence of the restriction enzyme used in the generation of the physical map is identical to at least part of the recognition sequence of the restriction enzyme used in the generation of the DNA sample.

To provide a method and an apparatus for decoding genome base sequences in which whole genome base sequences can be restored by recovering DNA from a chromosome while recording the presence position and determining the base sequences, and a method and an apparatus for preparing a genome physical map in which positioning of a genome library clone onto a genome is carried out by recovering DNA froma specific position on the chromosome and utilizing a part of the base sequence information. The shape of the chromosome is precisely acquired by an AFM search needle 7 also having a scraping mechanism, and minute fragments at accurate positions on the chromosome are continuously scraped. The scraped chromosome fragments are charged to an extraction means 8 of DNA and the extracted DNA is transferred to an amplification means 9. The amplified DNA is cloned to an adequate vector and a base sequence of a clone is successively determined by a base sequence-determining means 10. The resultant base sequence data are fed to a data processing mechanism 11, and the base sequences of the fragments and the whole chromosomes are restored.

The invention relates to a detection method of vegetal single copy genes based on fluorescence in situ hybridization of quantum dots. By preparing quantum dot coupled DNA (deoxyribonucleic acid) as a probe, according to the traditional fluorescence in situ hybridization method, the hybridization detection of vegetal single copy genes is carried out on interphase nucleuses, chromosomes, DNA fibersor the like. In the method provided by the invention, a direct marking method is adopted, thus an antibody detection process is omitted; and because the quantum dots have high fluorescence intensity and can resist photo-bleaching, the sensitivity and resolution of hybridization are improved, and the vegetal single copy genes can be quickly and effectively located. The method provided by the invention can be widely used for drawing physical maps and analyzing the composition, structure, rearrangement, evolutionary relationship and the like of genomes.
