The system described herein enables clinicians and researchers to use aggregated genetic and phenotypic data from clinical trials and medical records to make the safest, most effective treatment decisions for each patient. This involves (i) the creation of a standardized ontology for genetic, phenotypic, clinical, pharmacokinetic, pharmacodynamic and other data sets, (ii) the creation of a translation engine to integrate heterogeneous data sets into a database using the standardized ontology, and (iii) the development of statistical methods to perform data validation and outcome prediction with the integrated data. The system is designed to interface with patient electronic medical records (EMRs) in hospitals and laboratories to extract a particular patient's relevant data. The system may also be used in the context of generating phenotypic predictions and enhanced medical laboratory reports for treating clinicians. The system may also be used in the context of leveraging the huge amount of data created in medical and pharmaceutical clinical trials. The ontology and validation rules are designed to be flexible so as to accommodate a disparate set of clients. The system is also designed to be flexible so that it can change to accommodate scientific progress and remain optimally configured.

This invention provides a system and method for the design, prediction, and control of wireless communication networks by combining RF channel data from multiple lookup tables, each of which correlates an RF channel characteristic to some higher order network performance metric. Network performance predictions, and resulting network control instructions, are produced from look-up tables of measured or predicted data relating one or more RF channel characteristics to one or more network performance metrics. These lookup tables are uniquely constructed by site-specific location, technology, wireless standard, or equipment types.

A probable interpretation may be identified based on a confidence score for each of a set of candidate interpretations generated by the heuristic model. The model may be augmented or updated based on various information associated with the interpretation of the verbalization.

A method and apparatus provide for the negotiation of the content of a document via an electronic exchange. In one example an electronic exchange operates as a repository of forms of contracts. A user can initiate a negotiation process by selecting a form contract and, if desired, customizing the contract to a particular transaction. The user can then advise a third party as to the existence of the contract on the exchange. The parties can then conduct a negotiation of contract terms on the exchange in accordance with permissions prescribed by the exchanged and / or the user.

A novel on-the-fly data processing technique is useful for extracting signals from the azimuthal variation of the directional measurements acquired by a logging tool within a borehole. The relevant boundary, anisotropy and fracture signals are extracted from the formation response through fitting of the azimuthal variation of the measured voltages to some sinusoidal functions. The orientation of the bedding is also obtained as a result. The extracted directional signals are useful for obtaining boundary distances and making geosteering decisions. Two techniques involving inversion and cross-plotting may be employed, depending on the nature of the boundary. A Graphical User Interface (GUI) is part of a system to facilitate flexible definition of inversion objectives, for improving the inversion results, and for visualization of the formation model as well as inversion measurements.

This invention provides a system and method for efficient ray tracing propagation prediction and analysis. Given a site-specific model of a physical environment, the present invention places virtual obstructions known as reception surfaces within the environment. As radio waves are predicted to propagate through the environment and intersect with or encounter reception surfaces, the characteristics of the radio wave are captured and stored relative to the location of the interaction with the reception surface. The radio frequency channel environment at any point within the site-specific model can be derived through analysis of the radio wave characteristics captured at nearby reception surfaces.

A method and system allowing a user to interrogate external financial data quickly and efficiently and to drill up or drill down and across multiple graphical displays (“maps”) of information. Maps offer multiple dimensional filtration functionality enabling a comparison between different investment strategies. External financial data is received and calculations can be performed on the external financial data to generate one or more indicators. Internal financial data is calculated from one or more of the external financial data and the indicators. Filters are applied to the external and internal financial data, and the indicators. The filtered data is used to generate maps of certain data usually plotted against external and internal financial data or indicators. Icons are generated adding another dimension to the map without adding an additional axis of data. Further “depth” to a map can be added by generating a sub-map or a historical movement map.

A method of orienting a virtual camera for rendering a virtual endoscopy image of a lumen in a biological structure represented by a medical image data set, e.g., a colon. The method comprises selecting a location from which to render an image, determining an initial orientation for the virtual camera relative to the data set for the selected location based on the geometry of the lumen, determining an offset angle between the initial orientation and a bias direction; and orienting the virtual camera in accordance with a rotation from the initial orientation towards the bias direction by a fractional amount of the offset angle which varies according to the initial orientation.

Thus the camera orientation can be configured to tend towards a preferred direction in the data set, while maintaining a good view of the lumen and avoiding barrel rolling effects.
