Abstract: Provided are systems and methods for determining a multilocation predicted click-through rate (pCTR) for advertisements. The multilocation pCTR may be used to select and rank advertisements for advertisement auctions presented to potential advertisers. The multilocation pCTR may be based on a set of locations and probabilities for an estimation of a user's location, such by internet protocol (IP) address geolocation. The multilocation pCTR for an advertisement and a location set may then be determined from the single location pCTR for each location of the location set and the probability associated with each location.

Abstract: Aspect of the subject technology relate to a computer-implemented method for identifying geographic features related to a location lookup point. In some implementations, the method includes steps for receiving location information for a location look-up point, generating a plurality of search cells containing the location look-up point, wherein the plurality of search cells correspond with a respective plurality of hierarchical map cells and using the plurality of search cells to identify at least one geographic feature that is associated with at least one of the plurality of search cells. In certain aspects, the method can further include steps for providing at least one geographic feature to a user for display. Systems and computer-readable media for generating a geographic feature index are also provided.

Abstract: The invention relates to a device for metal welding, comprising a shielding element (1) which allows visual monitoring of the working process but protects the eyes from light radiation. The device comprises a video camera (5) which is directable towards the welding zone for recording the welding process in the form of video signals transmitted, via an image processing unit, to a video display unit (7), which the user is able to view and which is placed in or on the inside of the shielding element (1). The image processing unit reads process data from the video signals and presents the same via the video display unit.

Abstract: A device and a method for exhaust gas purification in a combustion engine comprises an arrangement (30) for recirculating exhaust gases from the engine (1) to an air intake (2) thereof. An exhaust gas purification arrangement (31) is adapted to convert constituents in the exhaust gases to less environmentally hazardous substances. A filter arrangement (32) comprises at least one filter (33) adapted to liberate the exhaust gases from particulate constituents. This filter (33) is adapted to purify EGR-exhaust gases only. According to another aspect of the invention, 2 the filter (33) is aged in heat transferring relation to at least one convener unit (34) of the exhaust gas purification arrangement so as to receive, from the convener unit, a heat addition to promote regeneration of the filter by combustion of paniculate constituents deposited therein.

Abstract: A method of modifying the course of combustion when evaporated black liquor is burnt in the furnace cavity of a recovery boiler is described. The method implies that lime sludge is supplied to the furnace cavity whereby the course of combustion is modified so that the temperature in the furnace cavity is raised. Also use of a recovery boiler for simultaneous combustion of black liquor and processing of lime sludge is described. In one embodiment of this use is disclosed that the processing of lime sludge is performed so that increased formation of calcium sulphide in the smelt of inorganic chemicals, which is formed in the recovery boiler, is obtained and/or so that the lime sludge is calcined.

Abstract: A method of producing white liquor having enhanced and/or reduced sulphidity in the recovery of chemicals in a sulphate pulp process is described. In the method one starts from a calcium sulphide rich smelt of inorganic chemicals, which has been obtained by simultaneous combustion of black liquor and processing of lime sludge. This smelt is treated with an aqueous solution, whereupon the calcium sulphide in the smelt is present in a solid form and the rest of the chemicals are in solution. Thereupon the solid calcium sulphide is separated and the obtained solution is processed as a green liquor in per se known manner to a white liquor having reduced sulphidity, whereupon optionally the separated solid calcium sulphide is mixed with the required amount of white liquor to a white liquor having enhanced sulphidity.
