A scalable system and method for locating a closest server in response to a client request via an interactive distribution network, such as the Internet, are provided. A closest content server is defined as having the least round trip time for responding to a client request. The system including a plurality of content servers; and a local server in communication with a plurality of clients, the local server acting as a proxy for communicating client requests from clients to a redirection server. Client network distance and load information is periodically collected at each content server in the network from clients communicating with each of the respective content servers. The redirection server periodically aggregates the network distance and load information from each content server to create client clusters from both current and previously aggregated network distance and load information. Each client cluster represents a division or partition of the total IP address space. Each client cluster is then mapped (paired) to one or more content servers in the network. The mapping or pairing is then utilized to respond to client DN requests received from any client in the network. Another aspect of the invention involves considering the respective capacities of the content servers in the network. A selection probability is assigned to each content server / domain index pair to prevent the repeated selection of the content server having lowest round trip time thereby overloading that server's service capacity. The selection probabilities assigned to each content server effect a load balancing to prevent overloading. Another aspect of the invention involves collecting the distance and load information without incurring any overhead cost by passively collecting TCP information as it is transmitted from clients in communication with content servers in the course of normal communications.

A packet switch identifies a communication flow carried across an IP network, observes the communication flow, and acquires statistics data thereof, such as the number of packets that passed through the switch, the number of discarded packets, time at which the packets arrived at the switch, and time at which the packets were sent out from the switch. The packet switch continues to acquire the statistics data on the communication flow while the communication flow continues. If the packet switch performs a relay function, it sends the locally obtained statistics data to the adjoining packet switch placed downstream. If the packet switch is a node placed on either end edge of the network, it gathers the statistics data obtained by and delivered from other switches in the network and sends the gathered statistics data to the network management system.

Method (300) for registration of two or more of frames of three dimensional (3D) point cloud data (200-i, 200-j). A density image for each of the first frame (frame i) and the second frame (frame j) is used to obtain the translation between the images and thus image-to-image point correspondence. Correspondence for each adjacent frame is determined using correlation of the ‘filtered density’ images. The translation vector or vectors are used to perform a coarse registration of the 3D point cloud data in one or more of the XY plane and the Z direction. The method also includes a fine registration process applied to the 3D point cloud data (200-i, 200-j). Corresponding transformations between frames (not just adjacent frames) are accumulated and used in a ‘global’ optimization routine that seeks to find the best translation, rotation, and scale parameters that satisfy all frame displacements.

A method of analysing electromagnetic survey data from an area of seafloor (6) that is thought or known to contain a conductive or resistive body, such as a subterranean hydrocarbon reservoir (12), is described. The method includes providing electric field data and magnetic field data, for example magnetic flux density, obtained by at least one receiver (25) from a horizontal electric dipole (HED) transmitter (22) and determining a vertical gradient in the electric field data. The vertical gradient in the electric field data and the magnetic field data are then combined to generate combined response data. The combined response data is compared with background data specific to the area being surveyed to obtain difference data sensitive to the presence of a subterranean hydrocarbon reservoir. Because the combined response data are relatively insensitive to the transverse electric (TE) mode component of the transmitted signal, the method allows hydrocarbon reservoirs to be detected in shallow water where the TE mode component interacting with the air would otherwise dominate. Furthermore, because there is no mixing between the TE and transverse magnetic (TM) modes in the combined response data, data from all possible transmitter and receiver orientations may be used. The background data may be provided by magneto-telluric surveying, controlled source electromagnetic surveying or from direct geophysical measurement.

A de-centralized, or distributed, monitoring system provides for data collection across a broad range of remote sources, collecting explicit data (which may be input directly by a user in the form of recommendation, comment, or vote) and / or implicit data (which may be collected by the system according to the user's browsing activity).

Data may be aggregated at the server, having been collected on the client side from multiple remote sources. During the aggregation process, data collected by the distributed monitoring system are categorized and organized in a central database for convenient retrieval. Implementation of the collected data includes both transmitting explicit data on demand as well as utilizing explicit data, implicit data, or a combination of both explicit and implicit data, in an open recommendation system which facilitates customization and personalization of the information retrieval process. A user may be provided with the option of turning off, or “deselecting,” the implicit data collection functionality of the system.

A gas separation apparatus combines the technologies of electrostatic precipitators and centrifugal particle separators into a single unit. At an inlet into the gas separation apparatus, a water spray is introduced into the gas stream. The water spray may include various chemical additives, typically selected to react with or neutralize the particulates as they are mixed with the water or for other benefit. The resulting water and particulate mixture, which is much more dense than air, is centrifugally separated and collected through a drain tube outlet. In addition to the centrifugal forces applied to the gas and water stream, an electrical field of magnitude sufficient to produce coronal discharge is also applied to a central electrode. The electric field is generated between the cylinder wall and the central electrode, to assist the centrifugal forces and thereby remove additional particulate beyond that ordinarily removed by a standard centrifugal separator. A vortex finder surrounds the central electrode and protects the electrode from undesirable exposure to water splashes or the like, while assisting with the centrifugal separation. The novel separation apparatus and technique offer particular synergy when applied to the effluent stream from a fossil-fuel electric power plant or other similar gas streams.

An RC filter is further provided to control the impulse and reduce the burden that would otherwise be placed upon the refreshing power supply. The novel separation apparatus and technique offer particular synergy when applied to the effluent stream from a coal-fired electric power plant or other similar gas streams.
