AUV path planning method in ocean current environment based on population super-heuristic algorithm

The invention, which belongs to the field of underwater robots, discloses an unmanned aerial vehicle path planning method in an ocean current environment based on a population super-heuristic algorithm. A population is initialized and initial comprehensive cost values of all individuals in the whole population are obtained according to the cost function; a population basic operation set and a corresponding operation selection probability vector are set; one individual in the population and a population basic operation corresponding to the maximum probability in the operation selection probability vector are selected, the individual is operated, the basic operation of the population is repeated until the entire population is traversed, so that the iteration is completed; the operation selection probability vector is adjusted again and next iteration is carried out until the iteration number reaches a set value; and after iteration completion, an individual with the lowest cost value isselected, one group of control points is formed by combining a starting point, an end point and a fixed control point of a B-spline curve, and an optimal path is generated. Therefore, problems that the path planned based on the existing AUV path planning method is not smooth and is tracked difficultly, and the tracking energy consumption is high are solved.

Methods of isolating bipotent hepatic progenitor cells

A method of obtaining a mixture of cells enriched in hepatic progenitors is developed which comprises methods yielding suspensions of a mixture of cell types, and selecting those cells that are classical MHC class I antigen(s) negative and ICAM-1 antigen positive. The weak or dull expression of nonclassical MHC class I antigen(s) can be used for further enrichment of hepatic progenitors. Furthermore, the progenitors can be selected to have a level of side scatter, a measure of granularity or cytoplasmic droplets, that is higher than that in non-parenchymal cells, such as hemopoietic cells, and lower than that in mature parenchymal cells, such as hepatocytes. Furthermore, the progeny of the isolated progenitors can express alpha-fetoprotein and / or albumin and / or CK19. The hepatic progenitors, so isolated, can grow clonally, that is an entire population of progeny can be derived from one cell. The clones of progenitors have a growth pattern in culture of piled-up aggregates or clusters. These methods of isolating the hepatic progenitors are applicable to any vertebrates including human. The hepatic progenitor cell population is expected to be useful for cell therapies, for bioartificial livers, for gene therapies, for vaccine development, and for myriad toxicological, pharmacological, and pharmaceutical programs and investigations.

Method for optimizing broken paper splicing and recovery problem through genetic algorithm

The invention discloses a method for optimizing the broken paper splicing and recovery problem through a genetic algorithm. The method is characterized by, to begin with, carrying out gene differenceassessment, and determining horizontal and vertical splicing difference between genes; then, initializing the entire population in a preset encoding mode, and carrying out assessment on chromosome fitness in the population by utilizing the gene difference and recording the optimum chromosome; then, entering an algorithm evolution process, randomly selecting chromosomes in the population as parental chromosomes to form cross combination, executing a cross operator and generating progeny chromosomes; randomly selecting one of four mutation operators to carry out mutation on newly-generated chromosomes and inserting the mutated chromosomes into the population; after execution of the cross and mutation operators, selecting a plurality of optimal individuals from the new population to form a new population; and if meeting termination conditions, terminating evolution and outputting gene arrangement information of the optimal chromosomes, or otherwise, continuing to return to the evolution flow for population evolution.

A method for anti-counterfeiting and identification of counterfeit products through the Internet

The invention discloses a method for preventing and distinguishing fake products by using the internet and two-dimension codes. The method comprises the following steps of: 1) randomly setting a set of unique two-dimension codes for each product by a manufacturer; 2) logging on an official database of the manufacturer through the internet to realize butting, wherein each time the two-dimension codes are scanned, a two-dimension code counter automatically accumulates a count; 3) scanning and logging on to verify the two-dimensional codes; and 4) judging whether a product is genuine by displaying the counting numerical value of the two-dimension code counter and the related identity information of a two-dimension code recognizer on the two-dimension code recognizer which scans the two-dimension codes at the same time. The method has the beneficial technical effect that the two-dimension code recognizer is combined with the internet to quickly identify the authenticity of the product on the spot through simple scanning, so that the aims of identifying and cracking down on fake products by the entire population of a country and ensuring that the fake products have no place to hide and disappear from the scene are achieved.
