摘要:
An oilfield data analysis system is based on a four-tier software model which includes a “shared earth model” and a federation of “directory services”. The first tier is a universal graphical user interface (GUI) which can operate on any inexpensive computer as well as on an expensive workstation, i.e. a “web browser”. The second tier is an application server which is coupled to users via the worldwide web and serves geoscientific software applications. The third tier is a geometric modelling system where geometric data is stored and processed. The third tier embodies the “shared earth model”. The fourth tier is a database management system where non-geometric data is stored. According to the invention, there can be (and preferably are) multiple instances of each tier. Communication of data between different tiers is accomplished via XML data exchange. According to a presently preferred embodiment, the geoscience applications served by the second tier are written as JAVA servlets and applications may communicate with each other without human direction by registering requests with “directory services”. Applications interested in certain types of data “listen” for “data events” being registered with directory services. The cost of utilizing an application can be based on a time-rental billing operation which is carried out automatically via directory services.

Social dilemma virtual world environment (VWE) software facilitates creation and usage of social dilemma tests or exercises for measuring and analyzing online interactive societies. An online interactive society arises whenever two or more people interact through a computer-based communication medium, which may include text or written communication, audio communication, still or motion video communication, or any combination of these communication formats. The social dilemma VWE software and the methodology of the present invention are capable of distinguishing the levels of cooperation and trust that are created by various interface and social factors within online interactive societies. Evaluating with social dilemma VWE software the effects of such social and interface factors on the degree of online cooperation allows such factors to be incorporated into the design and functionality of online interactive societies.

A model creation unit creates a three-dimensional optical model in which one or more optical components are disposed on an optical path extending from a light source to an image forming position. For creating optical axis models in the three-dimensional optical model, an optical axis auto-creation unit figures out behaviors of beams of light on the basis of predetermined set parameters. The optical axis auto-creation unit provides a display of the behaviors of beams of light in the three-dimensional optical model, for verification, and further provides a print output of letters or the like created by use of the model.

This invention specifies physics-like computational models called M models. These models enable the specification and design automation of an integrated architecture of a real system. A new class of adaptive systems engineering tools called Adaptive Model-Reference (AMR) tools, supports the M computational model. AMR tools are used to visually specify the integrated architecture model of a real system, assess it's value, and automate the static and dynamic binding of it's model components into adaptive systems. These systems can be adapted during system development to compensate for requirement changes and design errors, and during run time operation to compensate for unanticipated operational system conditions. AMR tools enable the verification and validation of adaptive real system designs built in compliance with a declared enterprise wide technical architecture. Architecture components can be specified using AMR tools or can be imported into the AMR tool set. AMR tools are specified using an open system architecture built as extensions to open system development environments, such as Microsoft Foundation and OLE, and run time system environments such as Microsoft Windows or Java Object Request Brokers (ORB).
摘要:
A method and system estimates manufacturing costs for conventional and advanced materials and processes based on a process-oriented approach. A computer system comprises an input display for selecting one or more designs and one or more design parameters. Cost models are based upon process-oriented manufacturing cost estimates for a plurality of designs utilizing materials and manufacturing of processes. Software is programmed to receive selected designs and selected design parameters from the input display and pass the selected designs and design parameters to the cost models. An output display shows the manufacturing costs estimated by the cost models for the selected designs and design parameters. A manufacturing process flow simulation model highlights and quantifies the magnitude of the manufacturing process cost drivers.

In the design method for nuclear reactor fuel management, nuclear reactor operation for sets of independent control variable values is simulated to produce associated sets of dependent performance variable values. Transfer functions are generated based on the sets of independent control variable values and the sets of dependent performance variable values. The transfer functions represent relationships between the independent control variables and the dependent performance variables. Additional sets of dependent performance variable values are then generated for additional sets of independent control variable values using the generated transfer functions. A set of independent control variable values for possible use in operating a nuclear reactor is then determined based on the sets of dependent performance variable values and the additional sets of dependent performance variable values.

A process of designing a screenless completion for an oil or gas well includes selecting an oil or gas well having known characteristics and inputting data about them into a computer; determining, through operation of the computer, whether a screenless completion should be performed on the selected well and, if so, identifying materials to be used in the screenless completion and in response indicating to a user a screenless completion design using the identified materials. Different types of screenless completion designs are made available. These steps can be performed for multiple wells, preferably with similar results for similar wells.

A designing apparatus comprises symbol mark memory for storing fluid controllers usable in fluid control devices in terms of symbol marks representing the functions, fluid channels and contours of the controllers, and a flowchart preparing device for preparing a flowchart of a fluid control device represented by symbol marks. The flowchart preparing device successively selects controllers, such as valves and massflow controllers, from a symbol mark file in the memory, arranges the selected controllers on a screen as suitably positioned, automatically selects a suitable coupling member for interconnecting adjacent two of the controllers from a coupling member data file and automatically arranges te controllers and the coupling members thus selected to prepare a flowchart.

A technique for translating design test bench generated signals into an Automated-Test-Equipment compatible format using existing digital pattern conversion tools. The technique uses sigma-delta modulation technology to allow conversion of analog and mixed signal stimuli into digital representations that can be converted for use in the target tester using existing digital pattern conversion tools.
