    摘要: A method and system for people flow statistics is disclosed in the invention, wherein said method comprises: multi-types of classifiers connected in parallel are used to perform the human head detection in the current image, the respective human heads in the current image are determined; the respective determined human heads are tracked to form the human head target movement tracks; and the people flow is counted at the direction of the human head target movement track. It can be seen, a plurality of classifiers connected in parallel are used in the invention, multi-types of human head targets, such as dark colored hair, light colored hair and caps of various colors, and the like, can be detected simultaneously.

    摘要: A method of producing metal oxide nanoparticles in an exfoliated silicate framework by forming an aqueous exfoliated silicate suspension by mixing a layered clay into water until clear. To which is added an acidic hydrated metal species precursor solution, formed by dissolving one or more transitional metal salts, and a non-ionic surfactant. This solution is then aged to precipitate a product precursor before the product precursor is separated and washed. The product precursor is calcined to form metal oxide nanoparticles in an exfoliated silicate framework.

    摘要: A method and apparatus for closing a vascular wound includes a guidewire and/or other surgical implement extending from the wound. A hemostatic material is advanced over the surgical implement and into contact with an area of the blood vessel surrounding the wound. The surgical implement is removed. Blood soaks the hemostatic material, and blood clotting is facilitated by the hemostatic agent within the material. A sealing layer of adhesive can be applied to the hemostatic material, confining the blood flow to the material. The vascular puncture wound is sealed by natural blood clot formation.
