Abstract: A swivel nozzle mechanism used with a high pressure fluid washer attaches to an output wand, typically through a flexible hose, to direct a high pressure fluid from the washer to a directed target. The swivel nozzle mechanism attaches to a distal end of the wand and is controllable by a handle mechanism attached to the wand which enables the rotation of a spray nozzle about an axis, normal to the wand axis, at the distal end of the wand. The handle controls the direction of rotation of the spray nozzle and has a plurality of stable operating points resistant to movement and thereby providing for prolonged use at a fixed position.

Abstract: An apparatus for constructing a high pressure fluid pump has a piston housing, a pump head connected to and supported by the piston housing, and a pump pedestal for supporting the pump head and the piston housing. The pump head receives water at low pressure and, in combination with the piston housing, produces fluid through a flow channel at high pressure. The combination of piston housing and pump head contain a “go-thru” valve which, in response to a suction on one side of the valve allows water at low pressure to pass through the valve into a receiving chamber, and in response to a high pressure fluid in the receiving chamber enables fluid at a high pressure to pass through the valve and eventually to an output port while closing off the input path. The pump further has an aluminum pump head or manifold appropriately structured to withstand high pressure fluid impact.

Abstract: A process for extracting hydrocarbon gases from marine sediment hydrates. In one embodiment, the process includes drilling from a sea floor into a hydrate rich subsea sediment to form at least one opening therein. Electrical heaters are inserted into the opening or openings. The hydrate rich subsea sediment is heated with the electrical heaters in order to release hydrocarbon gas therefrom. The released hydrocarbon gas is collected in an overhead receiver. The hydrocarbon gas forms hydrates again when moving through the cold sea water and inside the overhead receiver. The overhead receiver is raised to a sea depth where pressure and temperature permit the hydrates to dissociate and to release the hydrocarbon gas. The hydrocarbon gas is then gathered from the top of the overhead receiver.

Abstract: A method and system for searching for online users. A storage unit is set for an SP, and adapted to store the basic information and status information of users. Thus, after receiving an online user search request carrying search conditions from an XDMC, the SP may determine online users meeting the search conditions according to the basic information and status information of users in the storage unit, and returning search results carrying the basic information of the online users to the XDMC. The storage unit may be set for the SP or shared by the SP and the XDMS. Because the storage unit set for the SP stores the basic information and status information of users, the SP does not need to interact with the PS to obtain the status information of users and or interact with the XDMS to obtain the basic information of users after receiving an online user search request from the XDMC.

Abstract: A computer based method is provided for clustering related data representing objects of interest and information about levels of relatedness between objects. A weighted graph G is established on a computer. The graph has vertices and weighted edges joining pairs of vertices. Using the computer, the method finds all possible subgraphs H of G satisfying the following dynamic “edge-to-vertex” ratio: ? min ? ? P ? ? E ? ( H / P ) ? ? P ? - 1 > k where the minimum is taken over all possible partitions P of the vertex set of H, and E(H/P) is the set of edges crossing between parts of P. The subgraphs H found are identified as a level-k community if they are maximal, which means that there are no larger subgraphs containing it that satisfy the dynamic “edge-to-vertex” ratio for the same k. All level-k communities are output.

Abstract: A system for obtaining a resultant image and a method to utilize the same are provided. In particular, first and second images of a subject or a portion of the subject are obtained. The first image includes a first portion of the subject and a second portion of the subject, and each of the first image and the second image are different types of images. A first probability that the first portion has a contrast which is greater than a predetermined contrast and a second probability that the second portion has a contrast which is greater than the predetermined contrast then is determined using the second image. For example, the second probability is greater than the first probability. Moreover, the first and second portions of the first image are reconstructed to generate the resultant image. Specifically, the first portion is reconstructed based on the first probability and the second portion is reconstructed based on the second probability.
