摘要： A method and apparatus for dynamically balancing traffic loads in a communications system (such as satellite communications systems), based on a control of collision rates via the real-time control of throughput of channels of the communications system (such as a real time throughput of random access channels in a satellite network). The method and apparatus generates and transmits to remote nodes or terminals an operating probability based on the determined throughput for transmission using the communications channel. Also, the method and apparatus includes receiving by at least one terminal the generated operating probability and determining by the at least one terminal a transmission probability for the communications channel based upon the received operating probability, which can further be adjusted by one or more of a received upper or lower limit of the generated operating probability or a collision rate for the communications channel.

摘要： Electronic documents are retrieved from a database and/or from a network of servers. The documents are topic modeled in accordance with a Regularized Latent Semantic Indexing approach. The Regularized Latent Semantic Indexing approach may allow an equation involving an approximation of a term-document matrix to be solved in parallel by multiple calculating units. The equation may include terms that are regularized via either l1 norm and/or via l2 norm. The Regularized Latent Semantic Indexing approach may be applied to a set, or a fixed number, of documents such that the set of documents is topic modeled. Alternatively, the Regularized Latent Semantic Indexing approach may be applied to a variable number of documents such that, over time, the variable of number of documents is topic modeled.

摘要： Systems and methods are provided for implementing error identification and evaluation for a Reed-Solomon (RS) error-correction code (ECC) system. The BMA algorithm and/or list decoding may produce one or more error locator polynomials that are related to a decision-codeword. An accelerated Chien search can be used to more quickly evaluate the one or more error locator polynomial. If the accelerated Chien search identifies a valid error locator polynomial, a normal Chien search can be used to identify error locations, and Forney's algorithm or an equivalent technique can be used to evaluate the error values. A RS ECC decoder can include a computation circuit that evaluates an error locator polynomial or an error evaluator polynomial. The computation circuit can include computation components that receive the coefficients of the polynomials.

摘要： Preparation of semiconductor nanocrystals and their dispersions in solvents and other media is described. The nanocrystals described herein have small (1-10 nm) particle size with minimal aggregation and can be synthesized with high yield. The capping agents on the as-synthesized nanocrystals as well as nanocrystals which have undergone cap exchange reactions result in the formation of stable suspensions in polar and nonpolar solvents which may then result in the formation of high quality nanocomposite films.

摘要： Trick mode play for controlling video content playback can be realized using a semantic based criterion in order to achieve a more uniform playback experience for the viewer, when that viewer wishes to observe the video content presented according to a selected semantic. In one embodiment of the method, semantics associated with shorter time intervals in the video content are replayed in trick mode play proportionally slower than semantics associated with longer time intervals, wherein the proportionally is determined, at least in part, to the time interval associated with each semantic. In various embodiments, semantics can include scenes, audio, metadata, tags, and the like. The semantics based trick mode play approach allows for a more uniform viewing experience, on a time duration basis, from one semantic to the next.

摘要： The present invention provides methods for improving a ranking model. In one embodiment, a method includes the step of obtaining queries, documents, and document labels. The process then initializes active sets using the document labels, wherein two active sets are established for each query, a perfect active set and an imperfect active set. Then, the process optimizes an empirical loss function by the use of the first and second active set, whereby parameters of the ranking model are modified in accordance to the empirical loss function. The method then updates the active sets with additional ranking data, wherein the updates are configured to work in conjunction with the optimized loss function and modified ranking model. The recalculated active sets provide an indication for ranking the documents in a way that is more consistent with the document metadata.
