Abstract: A database management system generates a cache entry system view of a database cache. Also, a new column is generated for the cache entry system view, where the new column is an ENTRY_HASH column to identify each entry of the database cache. In an example, the database management system detects a request to remove a given entry of the database cache, where the request includes a given ENTRY_HASH value to locate the given entry of the database cache. In response to receiving the request, the database management system identifies the given entry of the database cache based on the given ENTRY_HASH value. Then, the database management system removes the given entry of the database cache. Also, the database management system notifies a cache manager that the given entry has been removed.

Abstract: Systems and methods for generating an interface including recommended elements selected using generated element type relation labels are disclosed. An interface generation request including at least one element type is received and a set of recommended elements is generated based on element type relations between the at least one element type and additional element types associated with a network interface. The element type relations are generated by at least one large language model and at least one optimal relation generation prompt. An interface including the set of recommended elements is generated.

Abstract: The present disclosure provides a position determining method, apparatus, electronic device and storage medium. The method includes: inputting a historical time queue and posture change information of a target object at a target point of time to a position estimation model to obtain an initial predicted position, wherein the historical time queue is used for storing historical position information of the target object at latest n historical points of time prior to the target point of time, and n is a preset positive integer not less than 2; and performing at least two iterative stages on the initial predicted position to obtain position information of the target object at the target point of time, wherein a positioning accuracy of any iterative stage is higher than a positioning accuracy of a previous iterative stage.

Abstract: Provided are an image display method and apparatus, an electronic device, and a medium, which relate to the field of computer technologies, in particular to the fields of cloud phones, cloud computing and cloud services. The specific implementation scheme is as follows: generating a simulated external display of a cloud device according to an acquired target resolution of a target client; and generating frame buffer data according to a frame buffer area of the simulated external display in the cloud device, and sending the frame buffer data to the target client so that the target client performs image display on a target interface according to the frame buffer data.

Abstract: The present disclosure provides a position determining method and apparatus, an electronic device and a storage medium. The method includes: determining whether a target object is located in a blind area of a camera at n historical moments of a historical time queue and a target moment; wherein the historical time queue is configured to store historical position information of the target object at latest n historical moments prior to the target moment, where n is a preset positive integer not less than 2; and in response to the target object being located outside the blind area of the camera at both of the n historical moments and the target moment, determining position information of the target object acquired by the camera at the target moment as the position information of the target object at the target moment.

Abstract: A mobile edge computing (MEC) task unloading method with a cache mechanism includes: S1: establishing a task unloading total delay model with a cache mechanism and a mobile device-side total energy consumption model based on a user task request; S2: based on the task unloading total delay model and the mobile device-side total energy consumption model, with a goal of minimizing a task unloading total delay and a mobile device-side total energy consumption, establishing a joint optimization model configured for task unloading and caching and having a constraint; S3: transforming the joint optimization model into a fitness function for a particle, where the user task request is the particle; and S4: determining an optimal solution of the particle by using a particle swarm algorithm based on the fitness function, where the optimal solution of the particle is an optimal task unloading decision of the user task request.

Abstract: An aromatherapy diffuser includes a diffuser body and a diffusion device. The diffuser body has an oil storage cavity for storing a predetermined amount of essential oil. The diffusion device is supported in the diffuser body, and includes an ultrasonic vibrator arranged to generate ultrasonic vibrations, in such a manner that when the diffusion body is partially immersed in the water stored in the container, the essential oil is released to the water from the oil storage cavity while the ultrasonic vibrator is arranged to cause ultrasonic vibrations in the water so as to agitate the water molecules for releasing negatively charged mist and essential oil into ambient air.
