Abstract: An electrical circuit is provided in a casing. The electrical circuit includes a capacitor having a particular function needed for realizing the electrical circuit. The electrical circuit includes an electrical component configured to generate heat due to energization. A flow creator creates, in the casing, an air flow that flows in a direction from the electrical component to the capacitor such that air heated by heat generation of the electrical component flows to the capacitor. A controller controls the flow creator. The capacitor has a characteristic that capacitance monotonically decreases or monotonically increases as temperature rises, in a part of a temperature range in which the electrical circuit operates. The controller detects a capacitance change due to a temperature change of the capacitor caused by the air heated by the heat generation, and controls the flow creator based on a detection result of the capacitance change.

Abstract: A system for providing client services with the assistance of a single source includes a distributed Internet application (DIA) maintained by an assisting party. A computer system is provided for accessing the DIA by a user. The DIA includes a presentation tier, an integration tier and a business tier. An application server couples the integration tier and the presentation tier to determine task sequencing in the presentation tier. A plurality of business units of the assisting party are provided in the business tier, the business units being accessible through the integration tier.

Abstract: The present invention includes a system and a method for processing large data sets that are too large to conveniently fit into a formal database application. The large data set processing system and method use a prediction model having a feature selection capability to process a fraction of the large data set and define useful predictors. The useful features are used to make predictions for the entire data set. The large data set processing system includes a useful predictor module, for defining useful predictors, and a feature-selection prediction model, for processing a portion of the data set (including the useful predictors) to obtain prediction results.

Abstract: One embodiment of the present invention provides a system for elevating a secondary file server to act as a new primary file server in a highly available file system. Upon determining that a primary file server in the highly available file system has failed, the system promotes the secondary file server to become the new primary file server. During this process, the new primary file server scans file objects to look for a file lock indication. Upon finding a file lock indication, the new primary file server converts an associated file identifier into a virtual node. Otherwise, conversion of file identifiers into virtual nodes is delayed until the first time a file is subsequently accessed by the new primary server, thereby speeding up the failover process.

Abstract: A method of accessing information from a collection of data includes receiving a query, augmenting the query with canonical non-terminal concepts, generating an inverse index of the collection of data, the inverse index including canonical non-terminal representations of the data and generating results to the augmented query in conjunction with the inverse index.

Abstract: A method and apparatus provide the ability to generate and use a database representing all solutions (legal combinations) satisfying all constraints of configuration problems on finite domains and/or intervals. The configuration space with all legal combinations is stored in a compact way in terms of nested arrays, where each legal Cartesian subspace has a unique index. Thus, the complete configuration space (which can be extended with object functions for optimization) is easily addressable by parallel indexing techniques and the database is therefore suitable for run-time applications (e.g. configuration on the Internet), which must be performed in real time.

Abstract: A system for providing coherent access to different versions of a group of documents stored in a file system and retrievable over the Internet from an HTTP server includes a state management server which stores registration data indicating the file paths of the documents in each version of the group and a set of index paths used by clients to reference documents in the group. State information identifying the version of said group previously accessed by a client is stored in a cookie which is associated with the domain of the state management server and the path of the group. A client requests a document from the group by issuing a request to an HTTP server including the index path of the desired document. The request and associated cookie, which is automatically transmitted by the client Internet software, is forwarded to the state management server. The state information stored in the cookie is extracted and used to determine which version of the group of documents should be accessed.
