Abstract: A fingerprint recognition system is disposed below a screen assembly of an electronic device and includes a light-emitting diode (LED), an image sensor, and a light shielding member. A light emitting surface of the LED faces the screen assembly and is configured to emit an optical signal. A photosensitive surface of the image sensor faces the screen assembly, where the optical signal received by the image sensor includes a fingerprint optical signal returned after being emitted by the LED to a finger, to generate a fingerprint image. The light shielding member is located between the LED and the image sensor, to block a part of signal light emitted by the LED.

Abstract: A method and system for code package. A dataset is generated according to a code package. The code package includes an image file associated with a container for a tenant. The dataset includes general information related to security aspects of the image file. The image file includes two or more image layers. Generating the dataset according to the code package includes: exporting an image layer from the image file; and obtaining a configuration file of the exported image layer as the dataset. In response to the vulnerability having been identified, the image file is updated with a patch that fixes the identified vulnerability. The patch includes a new image layer added to the two or more image layers in the updated image file.

Abstract: A method and system. A dataset is generated according to a code package. The code package includes an image file associated with a container for a tenant in a cloud environment. The dataset includes general information related to security aspects of the image file. The image file includes two or more image layers. A security indicator of the image file is extracted according to the dataset. A security level of the image file is determined by comparing the extracted security indicator of the image file with a security indicator of an authenticated image file. A vulnerability in the image file is identified based on the determined security level. In response to the vulnerability having been identified, the image file is updated with a patch that fixes the identified vulnerability. The patch includes a new image layer added to the two or more image layers in the updated image file.

Abstract: A simulation analysis method for an injection volume of alternate displacement of shale oil by carbon dioxide and nitrogen includes steps of simulating the alternate displacement of shale oil by carbon dioxide and nitrogen for multiple times through the core displacement simulation experiment, measuring the oil displacement efficiency change for every time, obtaining the porosity change in the entire displacement process through the porosity change before and after alternate displacement, and building the injection volume adjustment expression of alternate displacement of shale oil by carbon dioxide and nitrogen as a reference of the injection volume of alternate displacement of shale oil by carbon dioxide and nitrogen, so that the total displacement efficiency in the actual mining process is improved, thus increasing the production rate of shale oil and reducing the usage amount of carbon dioxide. A simulation analysis device is used to carry out the simulation analysis method.
