    摘要: Embodiments facilitate greater flexibility in definition of user segments for targeted advertising, by employing indexed semantic user profiles. Semantic user profiles are built through extraction of online user behavior data such as user search queries and page views, and include user interest information that is inferred based on user behavior. Semantic user profiles are then indexed to facilitate search for a set of users that fit specified semantic search terms. Search results for semantic profiles are ranked according to a ranking model developed through machine learning. In some embodiments, building and indexing of semantic profiles and learning of the ranking model is performed offline to facilitate more efficient online processing of queries.

    摘要: A method and system for automated magnetic resonance (MR) scan prescription is disclosed. A 3D MR scout image is obtained by an initial MR scan. The location of an optic nerve in the scout image is determined by registering a template image to the scout image using a hierarchical series of rigid registrations. The hierarchical series of rigid registrations utilizes a coarse to fine scheme to register regions in the template image to the scout image, starting with the whole template image and finishing with the optic nerve. A diagnostic MR scan is then aligned based on the location of the optic nerve in the scout image, and the diagnostic scan is performed resulting in a high quality diagnostic 3D MR image.

    摘要: The present invention is generally related to an electronic ballast, an ignition control apparatus used therein and associated method of operation. In one embodiment, an electronic ballast comprising an inverter and an ignition control apparatus which comprises a stability monitoring circuit and a controlled ignition circuit. The inverter converts a DC input voltage into an AC voltage to drive a gas discharge lamp. The stability monitoring circuit monitors whether the DC input voltage is stable. The controlled ignition circuit is electrically coupled to the stability monitoring circuit and the lamp, ignites the lamp based on the monitoring result. The controlled ignition circuit does not ignite the gas discharge lamp until the DC input voltage becomes stable.

    摘要: A method and system for automatic MR brain scan planning is disclosed. The method utilizes a set of 2D orthogonal localizer images to determine scanning planes for 3D diagnostic MR scans. A location of the mid-sagittal plane (MSP) is detected in each of a transversal localizer image and a coronal localizer image. A sagittal scanning plane is determined based on the location of the MSP in the transversal and coronal localizer images. A diagnostic sagittal MR scan is then acquired based on the sagittal scanning plane. The corpus callosum CC is segmented in a sagittal MR image slice resulting from the diagnostic sagittal MR scan. A transversal scanning plane can be determined based on a location of the CC in the sagittal MR image slice and the location of the MSP in the coronal localizer image, and a coronal scanning plane can be determined based on the location of the CC in the sagittal MR image slice and the location of the MSP in the transversal localizer image.
