摘要： During monitoring of IP network traffic, network application monitoring metrics are extracted, aggregated into logical group types and subsequently analyzed by identifying group sets of the logical group types, correlating anomalous conditions across the logically grouped and aggregated metrics, and isolating the anomalous conditions to one or more related members of the logical group types. The metrics may include usage metrics, network performance metrics and application performance metrics.

摘要： Client network traffic data and server network traffic data regarding a number of network nodes is collected and then grouped by IP address. The network nodes are divided into logical groupings and the network traffic data is presented in the aggregate for all IP addresses in each logical group. The logical groupings may be further divided by protocol, application, port and/or logical group-to-group. Each logical group can be further generalized as either a set of IP addresses (e.g., a business group) or a specific logical link between one set of IP addresses to another set of IP addresses (e.g., a business group link). Either or both of these “groups” may be divided in further logical sub-groups: for example, by protocol, application, port and in the case of business groups, group-to-group. The logical groups provide facilities for initial problem detection and identification while the logical sub-groups provide facilities for troubleshooting and problem isolation.

摘要： A system and method to visually navigate hierarchical data groups are provided. If a user wishes to graphically view network traffic data for a particular business group of network nodes, a network topology navigation tool may be provided to display to the user such information that is relevant to the selected business group and the corresponding hierarchy level. The user may also be permitted to access more detailed connection information through appropriate drill-downs.

摘要： Navigator methods are disclosed that are based on detecting a flow-sensitive signal within a subject, and using the position of the signal to track subject motion between imaging sequences. In a disclosed embodiment, the fast-moving blood volume in the left ventricle of the heart is detected and used as a reference point to correct for cardiac motion that results from respiratory motion in a subject. The navigator based on the position of the fast-moving blood volume in the left ventricle may be applied prospectively to shift a subsequent imaging slice to compensate for subject motion, and thereby provide MRI images with increased clarity and resolution.

摘要： Magnetic resonance imaging method and apparatus are provided for mapping the internal or bulk motion of an object by labeling the phase of a specimen magnetization with a selected spatial function and measuring changes in the phase of the magnetization. The spatial function is selectable to provide magnetization phase modulation corresponding to displacements in a selected direction, such as a radial or azimuthal direction. Methods and apparatus for producing images based on magnetization phase modulation acquire image data based on stimulated echos and stimulated anti-echos. In an embodiment, a series of 180 degree pulses produces alternating stimulated and stimulated anti-echos that are measured and assigned to respective images.

摘要： A method for making artificial suede-like leather product includes preparing a basic sheet member, applying an adhesive material onto the basic sheet member, applying flocks onto the adhesive material, and applying an electric energy onto the flocks, to erect and to implant the flocks on the adhesive material and the basic sheet member, and to form the artificial leather product. An outer covering material may then be applied onto the flocks and the adhesive material, and disposed between the flocks, and to have root portions of the flocks engaged within the outer covering material, and to have the flocks solidly secured to the adhesive material with the outer covering material.

摘要： A system and method of imaging based on the interaction of ultrasonic pulses with a magnetic field. A static magnetic field is applied to an object having conductive properties. An ultrasound pulse is propagated into the object, and an electrical signal is detected which is related to the interaction of the ultrasound pulse local displacement of the conductive object and the magnetic field. Alternatively, and equivalently, an electrical pulse is propagated into the object, and an ultrasound signal is detected which is related to the interaction of the electrical pulse generated in the conductive object and the magnetic field. The acquired acoustic signals or the acquired electrical signals are processed to provide an image of the object. The acquired signals are dependent on local conductivity as well as local acoustic properties.

摘要： A method, and related apparatus, for suppressing the magnetic resonance signal to an experimentally adjustable depth by applying a spatially inhomogeneous field between the slice-select pulse and the data acquisition. Eliminating the signal from near surface regions allows one to shrink the field of view of an image without introducing aliasing artifacts, thereby improving the image's resolution or decreasing imaging time. Experimental tests on a phantom and a human subject indicate that the depth of signal suppression may be continuously varied to depths of over 80 millimeters with modest requirements on power supplies, pulse sequences, and materials.
