Calculation methods. A calculation method implements a piece of the calculation framework. Different calculation method classes are used for the different operations that are required to complete a calculation within the calculation framework.

Computational method and system to perform empirical induction

The present invention is an improved computational method and system of empirical induction that can be used to arrive at generalized conclusions and make predictions involving longitudinal associations between and among variables and events. Empirical induction is used to gain scientific knowledge, to develop and evaluate treatments and other interventions, and to help make predictions and decisions. The invention, which is distinct from and often complementary to the statistical method, is applied to repeated measures and multiple time-series data and can be used to quantify, discover, analyze, and describe longitudinal associations for individual real and conceptual entities. Major improvements include provisions to define Boolean independent events and Boolean dependent events and to apply analysis parameters such as episode length and episode criterion for both independent and dependent variables, persistence after independent events, and delay and persistence after Boolean independent events. These improvements are in addition to levels of independent and dependent variables, delay after independent events, and provision to quantify benefit and harm across two or more dependent variables. Additional improvements include provisions to quantify longitudinal associations as functions of period or time and to compute values of predictive indices when there are two or more independent variables. Major applications and uses of the invention include data mining, the conduct of clinical trials of treatments for the management or control of chronic disorders, health-effect monitoring, the quantification and analysis internal control in adaptive systems, analyses of serial functional images, analyses of behavior and behavior modification, and use to create computerized devices and systems whose behavior can be modified by experience. The present invention is best implemented on the Internet.

System and method for integrated on-demand delivery of operating system and applications

The present invention discloses a system and a method for integrated on-demand delivery of operating system and applications, where operating system images are separate and distinct from application images. Integration of operating system streaming and application streaming services makes streaming delivery possible to a wide range of client devices, including those without any local disk space such as thin-clients and diskless workstations. In addition, by integrating the centralized management of operating system delivery and application delivery, the present invention provides a complete solution to server-centric application management, thereby further reducing the total cost of ownership of network-based computing approach. Implementing the operating management functions at the client machine level of specificity and application management functions at the user level of specificity combined with providing separate and distinct operating system images and application images provides an inherently canonical architecture that allows proper scaling and affords appropriate security management functions. The result is a complete, scalable, robust, and reliable server-centric application and operating system management system with a lower total cost of ownership than existing products.

Route calculation method for a vehicle navigation system

ActiveUS20050222764A1Increase route calculationIncrease and decrease broadcastInstruments for road network navigationRoad vehicles traffic controlNavigation systemReceipt
Traffic information, including flow information and incident information, obtained through a traffic management system for providing and facilitating the exchange of traffic information between a remote location and a vehicle may be used in route calculation by a navigation device. The navigation device may recalculate a route based on anticipated user error. Alternatively, the navigation device may recalculate a route using received traffic information triggered by the receipt of a traffic information update, or triggered by the passage of an amount of time. The broadcast rate of traffic information updates may vary temporally (providing more frequent updates during peak commute times) or geographically (providing more frequent updates to metropolitan areas with increased traffic information needs). If route calculation is triggered by an elapsed amount of time, the amount of time may vary to be shorter during peak commute times. Additional route calculation techniques allow the incorporation of historical traffic information or the use of the most recent traffic information if incomplete traffic information is available. Still further route calculation techniques may calculate a best route by avoiding zigzagging or evaluating an assigned cost of a potential route.

System and method for implementing electronic markets

An efficient system for implementing an electronic market. The system includes a first mechanism for defining a set of attributes and associated descriptor variables involved in market transactions. Importance values are assigned to the descriptor variables by the first mechanism. A second mechanism computes match scores for the market transactions based on the importance values. A third mechanism employs the match scores to clear the electronic market. In the specific embodiment, the first mechanism includes an administrator interface, which allows an administrator to define the descriptor variables. A configurator communicates with the administrator interface and allows the administrator to assign a first set importance values to corresponding descriptor variables. The first set importance values includes default importance values or importance values assigned to the descriptor variables by a seller seeking to transact with a buyer via the electronic market. The administrator interface allows an administrator to configure a user interface of the market to allow market participants to assign a second set of importance values to different descriptor variables. The second set of importance values includes buyer and seller importance values. The descriptor variables and associated descriptor importance values may be continuous or discrete. A matching engine computes the match scores for market transactions based on a predetermined evaluation method specified via the administrator interface and based on a unique match score computation method.
