    摘要： A data structure with associated algorithms for representing and reconstructing contaminant transport in realistic complex geometries, e.g. in cities and around buildings, is described (160). The data structure has a pair of two-dimensional matrices compressed and extracted from three-dimensional matrices describing the transport and dispersion of contaminants in complex geometries using full-resolution, time-dependent computational fluid dynamics or compete and detailed experimental data (130). A first matrix (220, 320) has numerical values, in which continuous, monotone, gauge-invariant contours of the same value represent an edge of a family of contaminant clouds transported from one edge of the domain. A second matrix (250, 350) contains numerical values, in which continuous, monotone, gauge-invariant contours of the same value represent an opposite edge of a family of contaminant clouds transported from the other edge of the domain. The dual-matrix data structure may be used by overlapping the two matrices (440, 480) within the domain, and reading the areas between the two edge contours crossing at particular locations of interest.

    摘要： A method and system of transforming a product development process to reduce time in bringing a product to market through high throughput experimentation and advanced statistics and informatics, to transform the product development to a level of higher correlation with engine tests, and to develop better commercial products. This is achieved by modeling in Silico a plurality of component molecular models; deriving in Silico molecular characteristics (descriptors) for each of the plurality of compiled molecular models; creating at least one combinatorial library database record for each of the formulations, the at least one record having a plurality fields for storing information about compositional characteristics; receiving specification requirements for a lubricating oil composition; selecting from a database entries corresponding to compositions having specifications comparable to the received specification requirements; formulating a new lubricating oil composition to comply with received specification requirements; testing the new lubricant oil for compliance with received specification requirements; repeating the selecting, formulating, and testing steps until compliance with received specification requirements is achieved; and correlating the new lubricating oil composition to actual engine performance.

    摘要： A multi-scale finite-volume (MSFV) method to solve elliptic problems with a plurality of spatial scales arising from single or multi-phase flows in porous media is provided. Two sets of locally computed basis functions are employed. A first set of basis functions captures the small-scale heterogeneity of the underlying permeability field, and it is computed to construct the effective coarse-scale transmissibilities. A second set of bases functions is required to construct a conservative fine-scale velocity field. The method efficiently captures the effects of small scales on a coarse grid, is conservative, and treats tensor permeabilities correctly. The underlying idea is to construct transmissibilities that capture the local properties of a differential operator. This leads to a multi-point discretization scheme for a finite-volume solution algorithm. Transmissibilities for the MSFV method are preferably constructed only once as a preprocessing step and can be computed locally. Therefore, this step is well suited for massively parallel computers. Furthermore, a conservative fine-scale velocity field can be constructed from a coarse-scale pressure solution which also satisfies the proper mass balance on the fine scale. A transport problem is ideally solved iteractively in two stages. In the first stage, a fine scale velocity field is obtained from solving a pressure equation. In the second stage, the transport problem is solved on the fine cells using the fine-scale velocity field. A solution may be computed on the coarse cells at an incremental time and properties, such as a mobility coefficient, may be generated for the fine cells at the incremental time. If a predetermined condition is not met for all fine cells inside a dual coarse control volume, then the dual and fine scale basis functions in that dual coarse control volume are reconstructed.

    摘要： A mill roll analysis system is described that includes a user interface module, a structural analysis engine, and an analysis control script (22). The user interface module receives mill roll design data from a remote user via a computer network (9). The analysis control script automatically directs the structural analysis engine to define and evaluate an appropriate analytical model for the mill roll design based on the mill roll design data (4). The mill roll analysis system presents an intuitive web-based interface for capturing the mill roll design data, and may present predefined mill roll applications and mill roll types for selection for the user. As a result, the remote user need not be familiar with the underlying analytical modeling techniques, which may be highly-complex by nature. Consequently, a user may utilize the system to evaluate and improve mill roll design in order to achieve increased product performance.
