摘要:
A method and system for patient-specific computational modeling and simulation for coupled hemodynamic analysis of cerebral vessels is disclosed. An anatomical model of a cerebral vessel is extracted from 3D medical image data. The anatomical model of the cerebral vessel includes an inner wall and an outer wall of the cerebral vessel. Blood flow in the cerebral vessel and deformation of the cerebral vessel wall are simulated using coupled computational fluid dynamics (CFD) and computational solid mechanics (CSM) simulations based on the anatomical model of the cerebral vessel.

A method and system for up-vector detection for ribs in a 3D medical image volume, such as a computed tomography (CT) volume is disclosed. A rib centerline of at least one rib is extracted in a 3D medical image volume. An up-vector is automatically detected at each of a plurality of centerline points of the rib centerline of the at least one rib. The up-vector at each centerline point can be detected using a trained regression function. Alternatively, the up-vector at each centerline point can be detected by detecting an ellipse shape in a cross-sectional rib image generated at each centerline point.

A method and apparatus are disclosed herein for retrieving network traffic data. In one embodiment, a networking apparatus comprises a memory; a network device; and a processing unit coupled to the network device and the memory. The processing unit is operable to execute a data engine that performs bulk data transfers from the network device periodically into a data buffer in the memory and translates data received from the network device, based on a mapping definition, into a user defined format for export to one or more applications running on networking apparatus.
摘要:
A demand-based load balancing function may be provided by one or more drive controllers that takes advantage of the affinity laws to linearize the control of the variable of interest (e.g., flow, pressure, etc.). Each drive controller may be set up by the user simply inputting a few values into the drive controller. Based on the inputs, the drive controllers may interpolate control points using an assumed linear relationship between the variable to be controlled (e.g., pressure) and the current driven to the pump. Feedback data from the system may be used to continually update the drive controllers so as to potentially allow them to better balance power usage to each pump.
摘要:
A method includes identifying one or more features of a short term profile of a user that are not included in a long term profile of the user, using the one or more features to identify one or more third party profiles having features that substantially match the one or more features of the user's short term profile, accessing the identified one or more third party profiles, and providing one or more content items included in the third party profile to the user, the one or more content items having associated features that match the one or more features of the short term profile. An alternative method includes accessing one or more third party profiles that are not a profile of the user, and using the accessed third party profile to identify a plurality of content items for recommendation based on a feature set of the third party profile.
摘要:
Ribs are automatically ordered and paired. After ordering ribs on each side, magnetic and spring functions are used to solve for rib pairing. The magnetic function is used to constrain possible pairs across sides, and the spring function is used to maintain the order on each side while accounting for missing or fused ribs.

摘要:
Methods for sequencing nucleic acids are presented. Sequencing is accomplished through the detection of a redox active species that is indicative of nucleotide incorporation. In embodiments of the invention, an electrochemical signal indicative of nucleotide incorporation is amplified through cycling before it is detected. Arrays are provided that are capable of massively parallel nucleic acid sequence determination.
摘要:
A programmable non-volatile device is operated with a floating gate that functions as a FET gate that overlaps a portion of a source/drain region and allows for variable coupling through geometry and/or biasing conditions. This allows a programming voltage for the device to be imparted to the floating gate through variable capacitive coupling, thus changing the state of the device. Multi-state embodiments are also possible. The invention can be used in environments such as data encryption, reference trimming, manufacturing ID, security ID, and many other applications.
摘要:
A housing structure useful for protecting and stabilizing internal elements, such as a lawn and garden sprinkler. A housing has a hollow cylindrical interior with an open top and bottom. A resilient member is fixed inside the housing, and a central opening in the resilient member accommodates the body of the sprinkler. An adaptor may be used within the resilient member to accommodate different sprinkler sizes. A cover plate fits in the top opening of the housing and includes a central opening that allows the sprinkler head to extend through the opening. The resilient member resists any lateral forces imparted against the sprinkler head. A notch may be formed in the housing to accommodate a water pipe that is coupled to the sprinkler.
