摘要： A method and apparatus for spatio-temporal compressive sensing, which allows accurate reconstruction of missing values in any digital information represented in matrix or tensor form, is disclosed. The method of embodiments comprises three main components: (i) a method for finding sparse, low-rank approximations of the data of interest that account for spatial and temporal properties of the data, (ii) a method for finding a refined approximation that better satisfies the measurement constraints while staying close to the low-rank approximations obtained by SRMF, and (iii) a method for combining global and local interpolation. The approach of embodiments also provides methods to perform common data analysis tasks, such as tomography, prediction, and anomaly detection, in a unified fashion.

摘要： A system and method provides an electronic content to a vehicle from access point(s) within a network using a controller. The controller divides the electronic content into one or more files wherein each file contains at least one packet, and generates two or more random linear combinations of the packets within each file. For each file, each random linear combination of the packets is replicated to a different access point within the network. The electronic content is provided to the vehicle using at least one of the different access points. The controller can also determine a set of nearest trajectories for the vehicle in a location database that match a recent location history for the vehicle. For each determined nearest trajectory, one or more mobility trajectories are determined for the vehicle, and a set of access points are determined that correspond to the determined mobility trajectories for the vehicle.

摘要： Methods are described for optimizing wireless networks in a predictable way, i.e., the performance optimized is achievable in a real network. The methods consist of two main components: (i) a novel model that captures the relationship between network topology, wireless interference, traffic demand, and MAC-induced dependencies to accurately predict the throughput of individual flows in the wireless network, and (ii) a model-driven optimization that uses this model to optimize the network for a given performance objective.

摘要： A method, system and computer program product for efficiently distributing video content. A peer-to-peer network and a content distribution network are used in combination to distribute video content. A content distribution network relies on servers distributed across the Internet to achieve high quality content delivery at a high cost. A peer-to-peer network distributes content among peers without incurring server side cost but may experience poor performance. The peer-to-peer network and the content distribution network are leveraged in a manner that achieves high content delivery and low cost by allowing the peer-to-peer network to serve as much content as possible while using the content distribution network to bootstrap the content in the peer-to-peer network and using it as a fallback whenever the peer-to-peer network has insufficient bandwidth, insufficient quality or when the missing piece of video content in the video buffer of the client device has an immediate deadline.
