Abstract: Embodiments of the present disclosure provide a method and a device for detecting defect of a meal box, a server, a device, and a storage medium. The method includes: receiving a detection request including an image of the meal box sent by a user terminal, the image of the meal box being obtained by an image acquirer of the user terminal; and performing defect recognition based on the image of the meal box and a defect detection model in response to the detection request.

Abstract: A method and an apparatus for inspecting a corrosion defect of a ladle are provided. The method includes: acquiring images from various angles using an image acquisition apparatus inside a to-be-inspected ladle; and inputting the acquired images into a defect inspection system to obtain a label representing a defect category, the defect inspection system including: a deep convolutional neural network that predicts a category of a corrosion defect of the ladle included in the images based on the input images. This method has the advantages of high safety, high accuracy and high real-time performance in inspecting the ladle status.

Abstract: The invention relates to a method of acquiring hematopoietic stem cells (HSCs) by means of three dimensional inducing system with high efficiency—which makes use of three-dimensional cell culture matrix or cell culture scaffolds, such as three-dimensional cell culture system which is made from hydrogel, seaweed and other materials, and/or associating stromal-cell including bone marrow cell, mouse bone marrow cell line OP9, OP9DL1 and so on, and/or associating multiple factors including mesoderm inducible factor, hematopoietic growth factor etc which can induce pluripotent stem cells to differentiate into hematopoietic stem cells.

Abstract: The invention discloses a battery connection device comprising a connection block positioned at an electrode end of a battery; the connection block is provided with a series connection mechanism at both ends respectively, and with a parallel connection mechanism at all sides respectively; the series connection mechanism is provided inside with a conductive slice electrically connected with the electrode end of the battery; the conductive slice is further led out to a fitting face of the parallel connection mechanism; and thus the conductive slices on the two connection blocks are electrically connected when the two batteries respectively fitted with the connection block are parallel. The invention can make each unit battery connected modularly in series or parallel like a building block; the battery does not further need electrode connection by welding or battery fixing by assembling, which is convenient for operation as well as safe and reliable.

Abstract: In accordance with one embodiment of the present invention, there are provided methods and mechanisms for determining an allocation of resources, including hardware resources in a computing environment. With these methods and mechanisms, it is possible for computing resource allocations to satisfy one or more operational considerations, such as for example without limitation: “reduce device heat dissipation”, “avoid single point of failure in switched network” and other allocation needs are contemplated.
