摘要： Novel methods of fabricating porous structures (e.g., nanostructures) and resulting structures are disclosed. The novel methods use precision optics to cure a slurry made from one or more powders mixed with photopolymers. Pore size control preferably is achieved by controlling the powder size and powder loading in the slurry. As the disclosed methods are based on optics to control the thickness preferably without any mechanical movements, extreme tight thickness tolerance, as well as control of the profile structure, may be achieved. The novel disclosed methods are highly-cost effective with shorter manufacturing cycle time compared to conventional methods. Moreover, a supporting substrate may not be required as the resultant structure made by the novel fabrication techniques disclosed herein has enough strength to be free-standing.

摘要： A method and a system provide regional content to users by associating data files with geographical properties and matching the geographical property of a data file with the geographical property of the user. The system extracts geographical information from a data file, and associates the data file with a source geographical property corresponding to the extracted geographical information according to a geographical information database. Upon obtaining a user geographical property of a user, the system provides the data file to the user if the source geographical property matches the user geographical property. The method and the system may be implemented using a geographical name lexicon or a geographical name suffix lexicon.

摘要： A method determines core geographical information in a document by computing a score for each geographical name found in the document. The computation of the score uses the appearance frequency of the respective geographical name and positional weights assigned to various types of appearance positions of the geographical name in the document. The system determines the core geographical information in the document based on the scores of the geographical names found in the document. The method may further compute aggregated scores of geographical regions related to the geographical names and determine the core geographical information using both the aggregated scores of geographical regions and the scores of individual geographical names to increase accuracy.

摘要： A method is described for the characterization of atmospheric particles by means of a lidar device. The method provides to send a laser pulse in the atmosphere, a part of which is directly backscattered by the particles in the atmosphere. A reflecting optical device is provided, that is positioned at a predetermined distance d from the lidar device, whereby a part of the laser pulse that directly reaches the reflecting device is backreflected and is later backscattered by the particles in the atmosphere thus generating a counterpropagating backscattering signal directed towards the reflecting device, which signal reaches the reflecting device and is backreflected towards the lidar device. The lidar device detects the direct backscattering and counterpropagating signals. The optical characteristics of the particles are determined on the basis of the direct backscattering signal and the counterpropagating backscattering signal.
