Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for determining image search results. One of the methods includes generating a plurality of feature vectors for each image in a collection of images, wherein each feature vector is associated with an image tile of an image, wherein each feature vector corresponds to one of a plurality of predetermined visual words. All images in the collection of images that share at least a threshold number of matching visual words associated with matching image tiles are classified as near-duplicate images.

Abstract: A cell and method for simultaneous electrochemical and EPR measurements, including a disposable assembly, allows for a single device to produce data for both electroanalysis and EPR spectroscopy by generating a Redox reaction to form free radicals. The cell includes first and second hollow tubes, with the second tube being removably insertable into the first hollow tube. The interior of the first tube contains an insulating material, an electro-conductive material, and a wire connector extending from the electro-conductive material and out the first tube. The interior of the second tube contains an electrolytic solution, an analyte, a working electrode, and insulating material surrounding the working electrode. The second tube is inserted into the first tube and a reference electrode is placed into the second tube. The cell is placed within an EPR spectrometer. A potential is applied to the reference electrode to generate the Redox reaction of the analyte.

Abstract: The method includes generating at least one base object, and generating at least one extendable object associated with the base object, the extendable object defining an insertion point and is configured to enable addition of new functionalities to an application including the at least one base object.

Abstract: Methods and systems for automatically generating pose estimates from uncalibrated unordered panoramas are provided. An exemplary method of automatically generating pose estimates includes receiving a plurality of uncalibrated and unordered panoramic images that include at least one interior building image, and extracting, for each panoramic image, feature points. The method includes generating a match matrix for all the panoramic images based on the one or more feature points, constructing a minimal spanning tree based on the match matrix, identifying a first and second panoramic image, based on the minimal spanning tree, wherein the second panoramic image is associated with the first panoramic image providing a navigation from the first panoramic image to the second panoramic image.

Abstract: A sensor in a network to which to route a packet is selected, where the sensor is selected independently of energy status of the sensors included in the network, and the sensor is selected by a source sensor. The packet is routed from the source sensor toward the destination sensor.

Abstract: A first query that is substantially similar to a second query is detected. A network of sensors includes a first sensor, a second sensor, and a data-source sensor, the first and second queries are addressed to the data-source sensor, and the first query is forwarded by the first sensor to the data-source sensor and the second query is forwarded by the second sensor to the data-source sensor. The data-source sensor provides, to the first sensor, results answering the first query. The first sensor provides the results to the second sensor.
