A display control method includes performing plane detection on a physical environment within a front field of view (FOV) of an augmented reality (AR) device, determining a first object in the physical environment, determining a display position of a second object based at least on the first object and a current FOV of the AR device, and displaying the second object at the display position. The display position includes a display height and a display distance.

Display control method and device

Embodiments of this application provide a combine antenna and an electronic device. The combined antenna includes a first antenna of an electromagnetic induction type and a second antenna of an electromagnetic radiation type. The first antenna includes a substrate having an electrical conductivity with a body portion of the second antenna connected to the substrate of the first antenna, the substrate serving as a reference ground portion of the second antenna.

Combined antenna and electronic device

Techniques are generally described related to tag refinement strategy. One example method for refining homonyms and synonyms in a plurality of tags may include receiving, by a tag refinement system, a plurality of tagging actions each of which associates one or more of the plurality of tags with a digital object. The method may further include extracting, by the tag refinement system, a first subset of tags from the plurality of tags, wherein the first subset of tags have a higher collective relativity-similarity score comparing to a second subset of tags selected from the plurality of tags, and the first subset of tags, different from the second subset of tags, have a same predetermined tag count as the second subset of tags.

Tag refinement strategies for social tagging systems

A portable terminal is described where the portable terminal includes a first frame body and a second frame body. The first frame body is used for an antenna unit of the portable terminal and a gap is set in a first partial area of the first frame body with the first partial area with a gap being set is covered by the second frame body.

Portable terminal

Technologies are generally described herein for extracting a representative motion flow from a video. Technologies are also generally described herein for retrieving a video utilizing the representative motion flow. The representative motion flow may be extracted utilizing a sliding window approach to generate interesting motion flows. The representative motion flow may be generated based on the interesting motion flows.

Representative motion flow extraction for effective video classification and retrieval

Techniques are generally described related to a flash-based buffer management strategy. One example method to manage a buffer for a computer system may include maintaining a page-action list for monitoring a plurality of operations being executed on the computer system and utilizing a plurality of buffer pages of the buffer. An example page-action list may contain a hot-access queue for recently accessed buffer pages and a cold-access queue for less accessed buffer pages. The example method may also include, upon a determination that the buffer is full, identifying a victim buffer page from the plurality of buffer pages for eviction and evicting the victim buffer page from the buffer. The victim buffer page may be selected from the cold-access queue and based on a page weight, which is calculated based on a page state of the specific buffer page and a page hotness prediction for the specific buffer page might be accessed by an incoming operation.

Buffer management strategies for flash-based storage systems

Techniques are generally described related to a flash-based buffer management strategy. One example method for managing a buffer for a computer system may include monitoring, by a buffer management module, a plurality of operations being executed on the computer system and utilizing a plurality of buffer pages of the buffer. The example method may also include, upon a determination that the buffer is full, identifying a specific buffer page from the plurality of buffer pages for eviction, wherein the specific buffer page is selected based on a page state of the specific buffer page and a page hotness prediction for the specific buffer page. The example method may further include evicting the specific buffer page from the buffer.
