Abstract: Techniques for automatically focusing searches conducted by a search engine are provided. According to one aspect, revised query terms are automatically generated based on text in links that are in incoming (and/or outgoing) link lists associated with documents that are referenced in initial search results generated based on initial query terms. For example, some of the phrases that appear in incoming (and/or outgoing) links associated with a result document may be selected. The selected phrases may be added to the initial query terms to generate revised query terms. These revised query terms may be submitted automatically to the search engine in order to produce a more focused list of revised search results. This process may be performed repeatedly, each iteration revising query terms generated by the previous iteration, until specified criteria are satisfied, at which point the final revised search results may be presented to a user.

Abstract: The present invention is directed towards systems and methods for determining one or more positions for one or more advertisements. The method of the present invention comprises receiving a result set comprising one or more advertisements ordered by expected revenue. A document is divided into one or more locations for displaying one or more advertisements. A first set of advertisements is selected from the result set to position at a primary location in the document, the selection based upon the expected revenue associated with the one or more advertisements. A second set of advertisement is selected from the result set to position at one or more additional locations of the given document.

Abstract: The present invention is directed towards systems and methods for determining the performance of a plurality of versions of a given advertisement. The method of the present invention comprises retrieving a first version of an advertisement and associated click through data, and retrieving a second version of the advertisement and associated click through data. A clickability score is calculated for the first version of the advertisement using the click through data associated with the first version, and a clickability score is calculated for the second version of the advertisement using the click through data associated with the second version. A difference in clickability scores is determined between the first and second advertisement. The clickability score associated with the first version of the advertisement is modified based upon the difference in clickability scores.

Abstract: The present invention is directed towards systems and methods for ranking one or more advertisements. The method of the present invention comprises retrieving a result set comprising one or more advertisements responsive to a request. A clickability score is calculated for the one or more advertisements comprising the result set. An expected revenue value is calculated for the one or more advertisements using the clickability scores of the one or more advertisements as well as an indication of revenue associated with the one or more advertisements. The one or more advertisements are ordered according to the expected revenue of the one or more advertisements.

Abstract: It is known to make the performance of a loudspeaker “environment adaptive” in controlling a filter unit based on a measurement of the velocity/acceleration of the loudspeaker diaphragm and the associated sound pressure in front of the diaphragm, by means of an accelerometer and a microphone, respectively, thereby determining the radiation resistance of the diaphragm. The two sensors have to exhibit a constant transfer function throughout the life time of the loudspeaker, which make them very expensive. With the invention it has been found that the accelerometer can be replaced by another microphone held in a small distance from the diaphragm, and this conditions the possibility of using the same microphone for both measurements, e.g. simply by physically moving the microphone from one position to another. It will then no longer be required to use long-time stable sensors, whereby the price of the sensor equipment can be reduced dramatically. Also alternative arrangements are disclosed.

Abstract: A computer implemented method of ranking search hits in a search result set. The computer-implemented method includes receiving a query from a user and generating a list of hits related to the query, where each of the hits has a relevance to the query, where the hits have one or more boosting linked documents pointing to the hits, and where the boosting linked documents affect the relevance of the hits to the query. The method associates a metric to each of at least a subset of the hits, the metric being representative of the number of boosting linked documents that point to each of at least a subset of the hits and which artificially inflate the relevance of the hits. The method then compares the metric, which is representative of the size of a spam farm pointing to the hit, with a threshold value, processes the list of hits to form a modified list based in part on the comparison, and transmits the modified list to the user.

Abstract: Humanized antibodies which bind the NR-LU-13 antigen, conjugates containing such antibodies, and their use in pretargeting methods and conventional antibody therapy and immunodiagnosis are provided.

Abstract: A system, computer readable medium and method for searching for recently altered documents on the World Wide Web is provided. The method selects a server to be searched or crawled by a Web crawler based on a user selected ranking. Servers are ranked by a filter program which compares a user query with the content of a server and the frequency in which content is altered. A top percentage of ranked servers are crawled and the recently altered information, such as hyperlinks, are then provided to the user.

Abstract: A method and corresponding apparatus for controlling the performance of a loudspeaker in a room includes the steps of, in a first acoustic environment, which may be regarded as a reference, determining the acceleration, velocity or displacement of the loudspeaker diaphragm and the sound pressure in front of the diaphragm, and, based on these quantities, determining the radiation resistance, radiated acoustic power or real part of the acoustic wave impedance. Thereafter, the above step is repeated in a second acoustic environment, which will normally be the actual listening room in which the loudspeaker is to be used.

Abstract: A grinding device for gate valves which can be attached in a simple manner to the interior of a valve seat. The valve can by a simple rotation back and forth of the grinding device, e.g. by means of cord drive, be ground very accurately by hand. By adjusting press members provided on the device, the grinding ring can also be made to press with varying degrees of force against the respective parts of the valve, such that the grinding effect can be regulated. Because the grinding ring is designed to use removable abrasive paper, it is also very simple first to carry out a rough grinding and thereafter to perform fine grinding. Adaptation of the device to valves of different sizes is simplified.

Abstract: A hydraulic motor has a sliding-vane circular rotor disposed in a substantially elliptically cylindrical rotor chamber formed in a body to which the rotor is rotatably mounted so as to define a pair of diametrically opposed arcuate work cavities. Working fluid is introduced under pressure to each of the cavities via an inlet port, and spent working liquid is withdrawn from each cavity via an exit port. Each exit port is displaced angularly from the inlet port in the direction of rotation of the rotor. The rotor carries a sufficient number of radially movable, spring biased vanes, which are slidably engageable with the walls of the chamber, that at least one vane is always disposed in cavity-dividing position in each cavity for application thereto of pressure of liquid in the cavity between the vane and the inlet port. Working liquid pressure is applied to the vane to urge the vane toward the outlet port and to turn the rotor about an axis of rotation thereof.
