Ranking with learned rules

Systems, methods and computer program products for the ranking of a target data set based on learned rules are disclosed. One embodiment is a method that includes generating a learned rule set from a training data record set, creating at least one prototype for each rule in the learned rule set to generate a prototype set, and ranking the target data record set using learned rule set and the prototype set. The generating of a learned rule set includes dividing the training data record set to a positive class and a negative class, and deriving the learned rule set for the positive class. Learning of rules includes deriving the most general projected rules with respect to remaining training data and then refining those rules, eventually selecting the best rules using an F-measure.

Link supportability in a WCDMA communications system

A method, computer program product, and system are provided for computing link supportability in a WCDMA communications system. For example, the method can be used to calculate link supportability of a transponder in satellite communications system (e.g. MUOS) in a user-to-base direction. This method can include expressing a carrier signal to noise ratio spectral density for a communication link of interest in terms of a transponder input power of the communication link of interest, a spectral overlap factor representative of one or more interfering communication links, and a transponder input power of the one or more interfering communication links. Assumptions and approximations can be made to simplify the spectral density expression in order to reduce a dimensionality of terms used in the computation of the expression. As such, in reducing dimensionality, the expression becomes a manageable computation for WCDMA communication systems to evaluate.

Generating identical numerical sequences utilizing a physical property and secure communication using such sequences

Substantially identical numerical sequences known only to stations A and B are generated in a manner not subject to duplication by an eavesdropper and not subject to cryptanalytic attack because they are not derived using a mathematical function (such, as for example, factoring). The sequences are independently derived utilizing a physical phenomena that can only be "measured" precisely the same at stations A and B. Signals are simultaneously transmitted from each station toward the other through a communication channel having a characteristic physical property capable of modifying the signals in a non-deterministic way, such as causing a phase shift. Each signal is "reflected" by the opposite station back toward its station of origin. The effect of the communication channel is "measured" by comparing original and reflected signals. Measured differences are quantized and expressed as numbers.

Airspace design evaluation

A computer based method, system and computer program product to assign a quality metric to an airspace design and optionally to compare it against design metrics, to determine a comparative quality metric. Factors contributing to quality of the airspace sector design are identified via user input and quantified to calculate a quality metric for the airspace sector design as a function of the quantified factors. Categories for each of the identified factors, and parameters for each of the identified categories are also identified via user input. Each parameter has an associated weight and a range of thresholds with associated multipliers. An associated multiplier from the range of thresholds for each identified parameter is also identified. The identified multiplier is multiplied with the associated weight for each identified parameter. The products for each identified parameter are then summed to obtain a quality metric.

Methods, systems and computer program products for filtering generally-broadcast messages received by a movable unit based on current spatial position, stored trajectory history, and probable future trajectories. A current spatial position of the movable unit is received and stored to form a stored trajectory history. A generally-broadcast message relating to a target geographical region is also received and stored. Potential trajectories of the movable unit are then computed over a pre-determined time based on at least one of the current spatial position, a current travel direction of the movable unit, and the stored trajectory history of the movable unit. The generally-broadcast message is then disseminated in response to at least one potential trajectory crossing into the target geographical region during the pre-determined time period. The generally-broadcast message may also be disseminated on the basis of specified user preferences.
