Abstract: Just as written languages appear random unless one knows the words, so too protein sequences can appear as random. By statistical measures they are far from random. Protein sequences contain nonrandom signals. Some signals are associated with structure and function. Methods to search for and identify such signals are provided. Two amino acid classes and the characteristics of their signals are described. Protein sequences are transformed into symbols using these classes and other sets of amino acids. Signals are identified from these symbols. Signal analysis has many applications. As an example, conserved signal patterns across different protein families are used to predict fold of query sequences.

Abstract: Disclosed is a method for inter-antenna baseline determination that uses an antenna configuration comprising a pair of relatively closely spaced antennas and other pairs of distant antennas. The closely spaced pair provides a short baseline having an integer ambiguity that may be searched exhaustively to identify the correct set of integers. This baseline is then used as a priori information to aid the determination of longer baselines that, once determined, may be used for accurate run time attitude determination.

Abstract: Navigation satellite receiver measurements of the acceleration of a moving vehicle are used to derive valuable attitude information about the vehicle. Three-dimensional accelerometer measurements aboard the vehicle are used to determine the specific force vector in the bow frame. The navigation satellite receiver measurements allow determination of the specific force vector in the earth-fixed frame. The specific force vector measured in both vehicle and earth-fixed frames can be used with additional information to derive vehicle attitude.
