Disclosed is a method, system, and program for providing access to spatial data. A request for data is received. Enterprise and third party data are integrated. The integrated data is processed. Spatially referenced results are generated using the processed data. The spatially referenced results are returned in response to the request.

Apparatus and methods for performing satellite proximity operations such as inspection, recovery and life extension of a target satellite through operation of a “Satellite Inspection Recovery and Extension” (“SIRE”) spacecraft which can be operated in the following modes (teleoperated, automatic, and autonomous). The SIRE concept further consists of those methods and techniques used to perform certain (on-orbit) operations including, but not limited to, the inspection, servicing, recovery, and lifetime extension of satellites, spacecraft, space systems, space platforms, and other vehicles and objects in space, collectively defined as “target satellites”. The three basic types of SIRE proximity missions are defined as “Lifetime Extension”, “Recovery”, and “Utility”. A remote cockpit system is provided to permit human control of the SIRE spacecraft during proximity operations.

The invention concerns a method for determining the position of an object (1) in a space, whereby the measurement parameters (4) of said object (1) are recorded with an optical photographing system (3) calibrated on a spatial system of coordinates (5) and the position of the object (1) in the spatial system of coordinates (5) is determined. In order to be able to determine in reliable manner the position, even with a limited number of photographing devices, it is proposed to detect simultaneously at least two measurement parameters (4) of the object (1) in a photographing device (3) and to use them to determine the position of the object (1).

A write-once-read-many (WORM) storage system that employs large-capacity and relatively inexpensive disks in connection with a file system on a file server is provided. The file system contains most or all of the required WORM functionality so as to impose a minimal footprint on client applications, client operating systems and open protocols if desired. The system is organized around WORM storage volumes that contain files that, when committed to WORM storage, cannot be deleted or modified. Any file path or directory tree structure used to identify the file within the WORM volume is locked and cannot be deleted. In one embodiment, the administrator creates a WORM volume, capable of storing designated WORM files. The client then creates an appropriate WORM file using the appropriate protocol semantics. The file is written to the volume and committed by transitioning the file attributes from a not-read-only to a read-only state. The- file system recognizes the persistently stored WORM attribute of any file in a WORM volume as WORM file. Henceforth, any attempt to modify the file attributes, write to the file, or delete the file, by clients, administrators or other entities is rejected and a request denied message is returned to the attempting party

The method for Hammerstein modeling of a steam generator plant includes modeling of the linear dynamic part of a Hammerstein model with a state-space model, and modeling the nonlinear part of the Hammerstein model with a radial basis function neural network (RBFNN). Particle swarm optimization (PSO), typically known for its heuristic search capabilities, is used for estimating the parameters of the RBFNN. Parameters of the linear part are estimated using a numerical algorithm for subspace state-space system identification (N4SID).

The present invention relates to a radar apparatus that uses a plurality of transmitting / receiving antennas A1-A4 and receives a reflected wave, of a transmitted wave, reflected from a target. By utilizing the property that the path of the transmitted wave from an antenna A1 and its reflected wave and the path of the transmitted wave from the next selected antenna A2 and its reflected wave share the same spatial system, and therefore that both received signals have the same characteristics in terms of frequency and phase, a judgment is made as to whether there exists any difference between the receiving characteristics of the antennas, and the received signal is corrected in accordance with the result of the judgment. It is also possible to judge the presence or absence of a change in the characteristic of each antenna, and apply a correction accordingly, even during the normal operation of the apparatus.
