A content delivery network (CDN) edge server is provisioned to provide last mile acceleration of content to requesting end users. The CDN edge server fetches, compresses and caches content obtained from a content provider origin server, and serves that content in compressed form in response to receipt of an end user request for that content. It also provides “on-the-fly” compression of otherwise uncompressed content as such content is retrieved from cache and is delivered in response to receipt of an end user request for such content. A preferred compression routine is gzip, as most end user browsers support the capability to decompress files that are received in this format. The compression functionality preferably is enabled on the edge server using customer-specific metadata tags.

Method for radio communication in a wireless local area network and transceiving device refers to wireless local area networks (WLAN) consisting of a multitude of transceiving devices of users (14, 15, 16 . . . N). Simultaneous scanning by their antenna beams in different directions by the transceiving devices (with the transceiving devices being in reception mode) and transmission of an omnidirectional signal in the form of calibration signal and data package by one of the transceiving devices of the network (with the transceiving device being in transmission mode), reception of the signal by the transceiving devices operating in reception mode and subsequent orientation of their antenna beams in the direction of signal source. The recognition and orientation is performed during the period of reception of the calibration signal. The Method increases the range of a WLAN, reduces the transmission time and improves quality and reliability of communication. Each transceiving device (1) includes at least one directional antenna (3) featuring a controllable directional pattern, switched-over by unit (4), reception / transmission mode switch (5), receiver (8), transmitter (10) and controller (11). Additionally a unit for signal detection (13) is incorporated in the device.

An improved system and method for a distributed column chunk data store is provided. A distributed column chunk data store may be provided by multiple storage servers operably coupled to a network. A storage server may include a database engine for partitioning a data table into the column chunks for distributing across multiple storage servers, a storage shared memory for storing the column chunks during processing of semantic operations performed on the column chunks, and a storage services manager for striping column chunks of a partitioned data table across multiple storage servers. Any data table may be flexibly partitioned into column chunks using one or more columns as a key with various partitioning methods. There may also be a storage policy for specifying how to partition a data table for distributing column chunks across multiple servers and for specifying a level of redundancy for recovery from failure of storage servers.

An adaptive “temporal audio scaler” is provided for automatically stretching and compressing frames of audio signals received across a packet-based network. Prior to stretching or compressing segments of a current frame, the temporal audio scaler first computes a pitch period for each frame for sizing signal templates used for matching operations in stretching and compressing segments. Further, the temporal audio scaler also determines the type or types of segments comprising each frame. These segment types include “voiced” segments, “unvoiced” segments, and “mixed” segments which include both voiced and unvoiced portions. The stretching or compression methods applied to segments of each frame are then dependent upon the type of segments comprising each frame. Further, the amount of stretching and compression applied to particular segments is automatically variable for minimizing signal artifacts while still ensuring that an overall target stretching or compression ratio is maintained for each frame.

The invention relates to the technical field of neural networks, and specifically provides a method and apparatus for quantifying and compressing a convolutional neural network. The invention aims to solve the existing problem of large loss of network performance caused by an existing method for quantifying and compressing a neural network. The method of the invention comprises the steps of obtaining a weight tensor and an input eigen tensor of an original convolutional neural network; performing fixed-point quantization on the weight tensor and the input eigen tensor based on a preset quantization bit width; and replacing the original weight tensor and the input eigen tensor with the obtained weight fixed-point representation tensor and the input feature fixed-point representation tensor to obtain a new convolutional neural network after quantization and compression of the original convolutional neural network. The method of the invention can flexibly adjust the bit width according to different task requirements and can realize quantization and compression of the convolutional neural network without adjusting the algorithm structure and the network structure so as to reduce the occupation of memory and storage resources. The invention further provides a storage apparatus and a processing apparatus, which have the above beneficial effects.

Domain specific compression may be applied to a column chunk to reduce storage requirements of column chunks and increase transmission speeds for sending column chunks between storage servers.

Disclosed is a method for transmitting user data objects from a data-supplying component or a data server to a telecommunication device of a user via a connection component. The data-supplying component is informed via profile information in a profile object what types of user data objects the connection component or the telecommunication unit is able to process on its own such that the data supplying component can specifically transmit user data objects to the telecommunication device, which belong to the type that the telecommunication device can process. Hence, the data-supplying component is prevented from sending user data objects of a type that has to be converted by the connection component on the transmission path in order to be able to processed by the telecommunication device.

The invention discloses a multi-user wireless communication system based on both-way trunk and a method thereof; the communication system comprises four multi-antenna transceivers (not only a transmitter but also a receiver) and a multi-antenna both-way trunk; each transceiver is composed of an orthogonal frequency division multiplexing (OFDM) modulator, an OFDM demodulator, a memory and a self-interference eliminator; the both-way trunk is composed of an OFDM modulator, an OFDM demodulator and a beam former and is a semi-duplex amplifying transmission relay. The communication method leads a complete communication process to be finished within two time slots; in the first time slot, the four transceivers send signals to the relay at the same time, and an orthogonal frequency division multiple access is adopted as a multiple access way; in the second time slot, the relay adopts orthogonal frequency division multiplexing / space division multiplexing multiple access (OFDM / SDMA) as a multiple access way for leading received signals after being processed to be broadcasted to the four transceivers. In the invention, two multiple access ways are integrated, and relay beam forming matrixes suitable for different requirements of relay antenna number are respectively designed by adopting the two methods, thereby effectively utilizing space diversity to eliminate interference among the transceivers, and compared with the existing relay communication technology, the higher system and speed are realized.
