The method further includes transmitting the received pilot symbols by TXes of the antennas of the base station, receiving the pilot symbols transmitted by the antennas of the base station by the reference antenna as r0,i pilot symbols, and calculating non-reciprocity compensation factors as r i , 0 r 0 , i .

Abstract: Social networking systems benefit from techniques that improve the ability of users to share online content with other users of a social networking system. In one embodiment, when a user types, pastes, or otherwise inserts a URL, or some other hyperlink, into a message or post to the social networking system, a set of data on the referenced hyperlink target is acquired and stored on a server of the social networking system. The stored data is analyzed, to automatically generate a preview for the hyperlink; and the hyperlink preview is transmitted to the client device for approval. In one embodiment, follow-up actions related to the content are performed when the content is posed, which enables users to perform social graph actions to user nodes and concept nodes related to the message or post. In one embodiment, the shared content is cached on the social networking system.

Abstract: In one embodiment, a computing device receives an image. A large hash value is generated for the image based on a content-aware hashing function, resulting in the large hash value having a first number of dimensions. A small hash value is calculated for the image based on the large hash value and a locality-sensitive hashing function. The small hash value has a reduced number of dimensions compared to the large hash value. The small hash values for two or more images, respectively, will be close to each other if the two or more images are similar in content, and the small hash values will be different if the images are not similar. The small hash value for the image is used to determine whether the image is similar to one or more other images.

Abstract: Technology is provided for a pivoting memory drive adapter. The memory drive adapter is used for adapting memory drives for insertion into a drive bay that is larger than the memory drives. The memory drive adapter includes an adapter frame and a memory carrier. The adapter frame has an envelope compatible with a hard disc drive (HDD) drive bay, for example, and includes a pair of spaced apart sidewalls each including a slot. The memory carrier includes a pair of pins extending from opposite sides of the memory carrier engaging a corresponding one of the pair of slots. Thus, the memory carrier can pivot with respect to the adapter frame. A pair of spaced apart ledges divides the memory carrier into two memory drive locations, each sized to receive a memory drive, such as a solid state drive (SSD).

The base portion includes a first side configured to confront a mounting surface and a second side opposite the first side. One or more apertures are formed through the base portion and positioned to receive a corresponding mounting feature of the mounting surface, such as a bridge lance. The cable control fingers each include an arcuate first end portion extending away from the second side of the base portion, a middle portion extending parallel to the base portion, and a second end portion positioned to retain one or more cables between the cable control fingers and the mounting surface.

Abstract: A confidence scoring system can include a model trained using features extracted from translations that have received user translation ratings. The features can include, e.g. sentence length, an amount of out-of-vocabulary or rare words, language model probability scores of the source or translation, or a semantic similarity between the source and a translation. Parameters of the confidence model can then be adjusted based on a comparison of the confidence model output and user translation ratings, where the user translation ratings can be selected or weighted based on a determination of individual user fluentness. After the confidence model has been trained, it can produce confidence scores for new translations. If a confidence score is higher than a threshold, it can indicate the translation should be selected for automatic presentation to users. If the confidence score is below another threshold, it can indicate the translation should be updated.

Abstract: In particular embodiments, one or more images associated with a primary user are received. The image(s) may comprise single images, a series of related images, or video frames. In each image, one or more faces are detected and/or tracked. For each face, a set of one or more candidates are selected who may be identified with the face. A candidate score is calculated for each candidate based on a computed measure of affinity of the primary user for a particular candidate, a facial recognition score comparing the candidate to the face, and a geographic proximity of the candidate to the primary user at a time when the one or more images were created. A winning candidate is selected based on the candidate scores.

Abstract: Particular embodiments of a computing device receive an indication of a character encoding system and a combining-character sequence. The character encoding system may comprise one or more ranges of character elements. The combining-character sequence may comprise two or more character elements. The two or more character elements may comprise at least one base letter and one or more combining marks. A mapping code may be determined for the combining-character sequence. If no mapping code exists, a next-available mapping code may be determined, and the combining-character sequence may be stored in association with the next-available mapping code in a data store on the computing device. A corresponding glyph may be determined based on the mapping code—if no glyph exists, the glyph may be generated or retrieved from a server and stored in association with the mapping code in the data store. Information may be provided to display the glyph.
