Abstract: A method and computer system for identifying internet web pages containing documents that comply with a predetermined XML schema. The method includes searching the internet with a search engine for web pages using initial search terms and identifying a first set of HTTP URLs, web crawling at least the first set of HTTP URLs to identify additional HTTP URLs, appending a query to the identified URLs, and evaluating the responses to the query to determine which responses comply with the predetermined XML schema. The XML schema can be a Web Mapping Services schema. The system can store responses that comply with the XML schema in a database of servers, periodically check the database for validity, and convert the map requests for map servers in the database to a GIDB Portal Interface API.

Abstract: A method of: introducing hydrogen and a feed gas containing at least 50 vol % carbon dioxide into a reactor containing a Fischer-Tropsch catalyst; and heating the hydrogen and carbon dioxide to a temperature of at least about 190° C. to produce hydrocarbons in the reactor. An apparatus having: a reaction vessel for containing a Fischer-Tropsch catalyst, capable of heating gases to at least about 190° C.; a hydrogen delivery system feeding into the reaction vessel; a carbon dioxide delivery system for delivering a feed gas containing at least 50 vol % carbon dioxide feeding into the reaction vessel; and a trap for collecting hydrocarbons generated in the reaction vessel.

Abstract: A computer-implemented inversion method for determining characteristics of a bottom roughness field using a numerical wave model is provided. Measured wave heights over an area of interest are compared to predicted wave heights calculated by a wave model using an estimated bottom roughness parameter. If the error between the measured wave heights and the predicted wave heights is within a specified tolerance level, the analysis ends and the value of the bottom roughness parameter used in the wave model is retrieved. If the error is not within the specified tolerance level, an Influence Matrix IM is used to obtain a revised estimated bottom roughness parameter. The wave model is re-run using the revised roughness parameter and the resulting predicted wave heights are compared to the measured wave heights. The inversion continues until the wave height error is within the specified tolerance level. When the inversion ends, the bottom roughness field that produced those predicted wave heights is retrieved.

Abstract: A computer based system and method for real-time display of co-registered historical and current side scan sonar imagery during a side scan sonar survey. Embodiments also include modules for detection of clutter in the current imagery, identification of features, extraction of snippets, filtering based on predetermined size and shape parameters, and determination if a current feature is the same as a previously identified contact from historical imagery.

Abstract: The two-piece end cap assembly has an end cap that has a groove around its perimeter and at least one cavity. The end cap is fixed in place inside the flare case with the cavities exposed. Sealant/adhesive is applied to the groove and cavity. A RAM cap, having a flange on its edge corresponding to the size of the flare case and a number of projections corresponding to the cavities, is installed on the top surface of the end cap. The sealant/adhesive in the cavities attaches the RAM cap to the end cap. The sealant/adhesive in the groove is forced to the edges of the end cap and provides a seal between the end cap and the flare case. Radar Absorbing Material is applied to the top and exposed edges of the RAM cap, completely masking the face of the flare and its edges.
