Systems and methods for generating a performance index are described. A rank score is generated for each investor relative to a group of investors of which the investor is a member. Generation of the rank score uses investment data of a portfolio of the investor, and the portfolio comprises at least one investment position. A set of investors is selected from the group of investors, and the selection is based on the rank score of each investor. The performance index is generated to provide a measure of performance of top individual investors over time relative to a market index. Generation of the performance index includes generating a composite portfolio comprising investment positions of each portfolio of each investor of the set of investors.

A system for controlling an aerospace vehicle using on-line inertia estimation may include an attitude sensor to measure an attitude of the aerospace vehicle. The system may also include a processor on board the aerospace vehicle. An inertia estimator operable on the processor may generate an on-line inertia estimate of the aerospace vehicle. A rate and attitude estimator operable on the processor may determine an angular position and angular velocity of the aerospace vehicle using the attitude measurement of the aerospace vehicle and the on-line inertia estimate for controlling movement and orientation of the aerospace vehicle without any rates of rotation of the aerospace vehicle being required.

Systems and methods for an investment trading platform are described. An investment platform forms electronic links among member investors and investment portfolios and brokerage accounts of the investors, wherein a portfolio includes at least one investment position. The investment platform shares between the investors the portfolio data or the portfolios and/or brokerage data of the brokerage accounts. A trading application programming interface (API) conducts operations in portfolios and/or brokerage accounts in response to the portfolio data and/or the brokerage data. The trading API conducts automatic operations in portfolios and/or brokerage accounts in response to the portfolio data and/or the brokerage data.

Systems and methods for ranking an investor are described. An investor is one buying an investment position. The ranking comprises generating a skill score for each investor of a plurality of investors, where the skill score represents an Information Ratio (IR) of the investor. The ranking comprises generating a persistence score for each investor of the plurality of investors such that the persistence score represents skill of the investor relative to a benchmark. The ranking comprises generating a confidence score for each investor of the plurality of investors. The confidence score represents an investment win percentage relative to an investment loss percentage. The ranking comprises generating a rank score for each investor by combining the skill score, the persistence score and the confidence score. The rank score categorizes the investor relative to other investors based upon historical investment data and real-time brokerage account data.
摘要:
A system and a method for detecting and capturing information corresponding to split tests and their outcomes are disclosed. The system identifies a split test being run on a third-party website or web page. The split test comprises one or more experimental arms corresponding to modifications of the third-party website or web page. The system identifies the arms of the split test and monitors changes in traffic allocation to the arms of the split test. Further, the system identifies one or more experimental arms as being winner arms based on an increase in the traffic allocation to the arms or modifications contained in the arm or arms being detected on the website or web page following the conclusion of the test. In one embodiment, the system identifies one or more experimental arms as being winner arms when the traffic is allocated substantially or completely to the arms. The system terminates identification of the split test being run on the third-party website or web page upon detection of the winner arms.

A system, method and device for communicating over a power line are provided. In one embodiment, the device includes a controller, a first port in communication with the controller and configured to communicate over a power line via any of a plurality of frequency bands, and a second port in communication with the controller and configured to transmit and receive broadband communications. The first port may be configured to select one of the plurality of frequency bands for communications and the controller configured to provide routing functions for data received via the second port to be transmitted via the first port. The second port may comprise a wireless modem or a modem configured to communicate over a power line via broadband communications. The broadband communications may use a frequency band having a bandwidth greater than at least five of the plurality of frequency bands. The device may communicate on multiple frequency bands concurrently and may select or change frequency bands and/or the modulation scheme based on channel conditions or operational parameters.

A system and method for determining one of a plurality of power line conductors to which a remote device is electrically connected is provided. In one embodiment the method includes transmitting a data beacon, determining a relative time period associated with each power line conductor between a zero crossing of the voltage of the power line conductor and the transmission of the data beacon, receiving the data beacon with the remote device, determining a first time period between reception of the data beacon and a zero crossing of a voltage at the first remote device, and transmitting data of the first time period to a computer system. The method further includes with the computer system receiving the data of the first time period, determining that the first time period satisfies a similarity threshold with a relative time period associated with a first power line conductor, and storing in a memory information associating the first remote device with the first power line conductor.
