Abstract: Aspects of the present disclosure relate to remote configuration of a computing machine. A deployment server receives a request specifying a software configuration and a hardware configuration for a computing machine. The deployment server identifies, out of a plurality of computing machines available for deployment, a specific computing machine meeting the hardware configuration. The deployment server configures the specific computing machine based on the software configuration. The deployment server provides an output indicating that the specific computing machine is configured according to the request.

Abstract: A tunable diode laser absorption spectrometer and a method of processing absorption spectra is used to measure concentrations of selected fuel gas components and calculate several fuel gas parameters, including heating value, relative density, compressibility, theoretical hydrocarbon liquid content and Wobbe index. In the described incarnation, a tunable laser diode directs near-infrared light into an optical cavity through a sample of fuel gas. A sensor measures intensity of light exiting the cavity as the laser wavelength is tuned over a specified range to construct a cavity-enhanced absorption spectrum for the fuel gas. A set of basis spectra for expected component species is used to analyze the spectrum and determine component concentrations, including methane, ethane, carbon dioxide, and other discrete and structured absorbers. Critically, a generic broadband absorption is used to model higher hydrocarbons that present themselves as nearly featureless absorption spectra.

Abstract: A system is described for controlling access to resources using an object model. Users can specify use cases for accessing resources. The user may be granted access if the user satisfies qualifications required for accessing the resource, selected a use case permissible for accessing the resource, and satisfies qualifications required for the use case. Use cases, qualifications, resources, and/or links between them can be implemented using an object model. The system can be used in addition to authentication and authorization.

Abstract: An ammonia sensor can include a laser detector configured to provide stable sample readings. The sensor can implement a method including processing the recorded intensity of the laser beam to determine a first harmonic component and a second harmonic component and the amount of ammonia in the sample.

Abstract: An Internet search engine is disclosed. The search engine is capable of producing relevant search results in a ranked order, which is at least partially determined by the web site providers themselves. The search engine is preferably fee-based and policed to provide relevant search results to the end user.
