Abstract: Nanoparticles in a colloid are purified, with the colloid including a fluid, unwanted matter, and the nanoparticles to be purified. An electric field is applied that is substantially spatially uniform over a distance that is at least equal to a characteristic dimension of the nanoparticles, so that at least some of the nanoparticles move towards at least one collection surface as a result of the force arising between their electrical charge and the electric field, whereupon nanoparticles are collected on said at least one collection surface. The collection surface(s) may be one or more electrodes to which a voltage potential is applied. The collected nanoparticles are then removed from the collection surface, e.g., by dispersing them into another fluid.

Abstract: On-line and computationally efficient methods and systems are provided for back resolving path names of files from inode numbers during data access request processing. As a result, a near real-time recording of data access events is achieved, including identification of the user who performed the access, and the full path name of the data object that was accessed. In a typical application, access events are collected for use in access control of storage elements in complex organizational file systems.

Abstract: A system for locating electromagnetic signal sources via the rotational Doppler effect whereby a radar station generating electromagnetic signals, such as radar frequency signals, initially scans the sky for aircraft. An aircraft having the system operationally installed thereon and utilizing apparatus or navigational systems already present on the aircraft receives radar signals. The system is programmed to capture radar signal parameters and extract the rotational Doppler frequencies induced by the motion of the aircraft. The angular velocity of the host platform is often the dominant source of this frequency; however, lateral velocity is not detrimental to the process. The measurement of the rotational Doppler frequency is accomplished through antennas presently installed on large numbers of military aircraft with no requirement for phase calibration of the electrical paths between antennas and receiver.
