    Abstract: The present invention relates to a system for three-dimensional (3-D) acoustic imaging of a scattering structure using information from a two-dimensional (2-D) image. The system uses a characterized sensor array to emit a signal from the sensor array into an object of interest to generate at least one 2-D representation of the object of interest. The 2-D representation comprises a plurality of x and y coordinate pairs and at least one candidate scattering structure. The candidate scattering structure comprises a shape defined by at least one pair of x and y coordinates. The candidate scattering structure shape is restricted to at least one pair of x and y coordinates. The pair of x and y coordinates of the candidate scattering structure shape are then compared with a first coordinate-dependent response function to assign an x, y, and z position of a scattering structure in 3-D space.

    Abstract: A photovoltaic system for generating electrical power on farmland while minimizing reduction of solar radiation incident on ground due to shadowing, including a photovoltaic module having a first photovoltaic face defining a first plane, a normal axis extending from the first plane, a first pivot axis extending through the photovoltaic module, a second pivot axis extending through the photovoltaic module, at least one motor operationally connected to pivot the photovoltaic module about at least one pivot axis, and an electronic controller operationally connected to at least one motor. An incident solar ray strikes the photovoltaic module at an angle of incidence defined as an intersection of the incident solar ray and the normal axis. The electronic controller sends signals to the at least one motor to maintain the angle of incidence as close as possible to ninety degrees.

    Abstract: A method and computer program product for providing a random linear coding approach to distributed data storage is presented. A file is broken into a plurality of pieces. For every peer (peer means storage-location with limited storage space), the number of coded-pieces the peer can store is determined. Each of the coded-piece is determined by taking random linear combination of all the pieces of the entire file. The associate code-vector is stored for every coded-piece. The file is retrieved by collecting code-vectors and the coded-pieces from the peers and viewing the collected code-vectors as a matrix. When a dimension of the matrix is equal to the number of pieces of the file, the file is recovered using the collection of code vectors in the matrix.
