Abstract: Embodiments of methods, systems, and storage media associated with height-based item retrieval are described. A product demand determination system (“PDS”) may receive an indication of a product which a customer may desire to purchase. If the product is not available for purchase, the PDS may request information about the desired product. The PDS may then generate a product demand page which may allow customers to provide feedback as to whether the desired product should be sold. The PDS may also determine, based in part on the feedback, whether the e-commerce system should provide the desired product for sale based on various market considerations. Additionally, the PDS may be configured to receive seller information from one or more sellers who may wish to sell the desired product or service. Other embodiments may be described and/or claimed.

Abstract: Examples described relate to secure communication between services hosted on a private cloud and a public cloud. In an example, an agent on a private cloud may poll a secure server on a public cloud to determine whether the secure server includes a request for a service hosted on the private cloud. The request may be made by a service hosted on the public cloud. In response to a determination that the secure server includes the request for the service hosted on the private cloud the agent may retrieve the request from the secure server on the public cloud. The request may be executed on the private cloud, and a response may be generated. The agent may provide the response to the secure server on the public cloud. The response may be shared with the service hosted on the public cloud by the secure server.

Abstract: Example techniques for updating of container-based applications are described. In an example, a second version of an application code or application code changes are retrieved from a code storage location. Based on the retrieved second version or the retrieved application code changes, an application hosted in a container is updated.

Abstract: A method includes determining, by a cloud computing system, a number of radar events detected by wireless access point (WAP) devices of a wireless mesh network and by channels associated with respective ones of the WAP devices. The method includes determining a first WAP device has detected a fewest number of radar events and that a first DFS channel, of the first WAP device, has detected a fewest number of radar events as compared with a number of radar events detected via each of the other DFS channels of the first WAP device. The method includes assigning the first WAP device to be a master on the first DFS channel and transmitting, to the first WAP device, a message containing first assignment information regarding the first WAP device being assigned as the master on the first DFS channel.

Abstract: A computer-implemented method include sending a first cycle of received event data to an external system for processing and while waiting for the external system to confirm that processing of the first cycle of received event data has been completed, receiving a stream of additional event data for processing and assigning some of the additional event data to a second cycle of received event data, wherein the second cycle has a scheduled transmission time to be sent to the external system for processing. The second cycle of received event data is prevented from being sent to the external system when the scheduled transmission time arrives because the external system has not returned confirmation that processing has been completed for the first cycle.

Abstract: Embodiments of the present disclosure discloses a method for enabling CSI feedback in Multiple Input Multiple Output (MIMO) wireless communication system comprising at least one user equipment (UE) and at least one base station (BS). The UE receives a plurality of downlink (DL) channel state information CSI from the BS and generate an explicit CSI from the received DL CSI. The UE determines a range of frequency domain values and channel state values from the received DL CSI. Upon determination, the UE performs IDFT to determine time domain channel impulse response matrices for the range of frequency domain values and perform CSI quantization. In another embodiment, the processor performs CSI quantization on either full range or a partial range of the time domain channel impulse response matrices to obtain optimized time domain channel explicit CSI and transmit the generated explicit CSI as a feedback to the one or more BS.

Abstract: Distributed database management systems may perform range queries over the leading portion of a primary key. Non-random distribution of data may improve performance related to the processing of range queries, but may tend to cause workload to be concentrated on particular partitions. Groups of partitions may be expanded and collapsed based on detection of disproportionate workload. Disproportionate write workload may be distributed among a group of partitions that can subsequently be queried using a federated approach. Disproportionate read workload may be distributed among a group of read-only replicated partitions.

Various corresponding systems, methods, and non-transitory computer-readable media are also disclosed.

Abstract: Embodiments of the present disclosure relate to a method and system to generate a waveform in a communication network. The transmitter receives an input data and transmit a generated waveform to another communication system. The input data is spread with a spread code to generate a spread data and rotated using a constellation rotation operation to produce a rotated data. The rotated data is then precoded using precoding filter to produce a precoded data, and transformed into DFT output data using DFT operation. The DFT output data is then mapped with subcarriers to generate the sub-carrier mapped DFT data and modulated using Orthogonal Frequency Division Multiplexing (OFDM) modulation to generate the waveform with low PAPR.

Abstract: The present disclosure discloses a method and a system for transmitting DFT-s-OFDM symbols. A data sequence for transmitting as an OFDM symbol is received as input from a data source. A reference sequence for transmitting along with the data sequence as the OFDM symbol is generated and time-multiplexed with the data sequence, to generate a multiplexed sequence.

The transmission of the reference sequence and the data sequence in a single OFDM symbol provides better bandwidth utilization and flexibility in modulation of the reference sequence and the data sequence.

Abstract: Embodiments of the present disclosure are related, in general to communication, but exclusively relate to method and receiver for detecting data in a communication network. The method comprises transforming by a receiver, a received signal in to frequency domain to generate transformed signal. Also, the method comprises equalizing the transformed signal to obtain an estimated precoded signal, which is transformed using inverse Fourier transform to obtain a time domain signal. The time domain signal is de-rotated to produce de-rotated data, on which processing is performed by separating real part and imaginary part associated with the de-rotated signal. The real part and the imaginary parts are filtered and combined to produce a signal, that is demodulated to detect the signal.
