摘要:
A method for receiving a declarative specification including a plurality of stages. Each stage specifies an atomic operation, a data input to the atomic operation, and a data output from the atomic operation. The data input is characterized by a data type. Links between at least two of the stages are generated to create a data integration workflow. The data integration workflow is compiled to generate computer code for execution on a parallel processing platform. The computer code configured to perform at least one of data preparation and data analysis.

Methods and arrangements for processing hierarchical data in a map-reduce framework. Hierarchical data is accepted, and a map-reduce job is performed on the hierarchical data. This performing of a map-reduce job includes determining a cost of partitioning the data, determining a cost of redefining the job and thereupon selectively performing at least one step taken from the group consisting of: partitioning the data and redefining the job.

摘要:
A reaction-based process has been developed for the selective removal of carbon dioxide (CO2) from a multicomponent gas mixture to provide a gaseous stream depleted in CO2 compared to the inlet CO2 concentration in the stream. The proposed process effects the separation of CO2 from a mixture of gases (such as flue gas/fuel gas) by its reaction with metal oxides (such as calcium oxide). The Calcium based Reaction Separation for CO2 (CaRS—CO2) process consists of contacting a CO2 laden gas with calcium oxide (CaO) in a reactor such that CaO captures the CO2 by the formation of calcium carbonate (CaCOa). Once “spent”, CaCO3 is regenerated by its calcination leading to the formation of fresh CaO sorbent and the evolution of a concentrated stream of CO2. The “regenerated” CaO is then recycled for the further capture of more CO2. This carbonation-calcination cycle forms the basis of the CaRS—CO2 process. This process also identifies the application of a mesoporous CaCO3 structure, developed by a process detailed elsewhere, that attains >90% conversion over multiple carbonation and calcination cycles. Lastly, thermal regeneration (calcination) under vacuum provided a better sorbent structure that maintained reproducible reactivity levels over multiple cycles.
摘要:
A method of associating a given text document with relevant structured data is disclosed. The method receives as inputs a text document, and structured data in the form of a relational database. The method then identifies terms in the text document, and searches and queries the structured data using the terms to identify fragments of the structured data that are relevant to the document. Finally, the text document and the identified fragments of structured data are output to a user.
摘要:
Online purchasing of components compatible with particular hardware devices of a computer system. In one aspect, the identity of a hardware device capable of communicating with computer systems is automatically determined. At least one component for the hardware device is displayed on a computer system based on the identity of the hardware device such that the user can select the at least one component for purchase, where the at least one component is compatible with and for use with the hardware device.

摘要:
A technique for dynamic integration and semantic analysis of structured data and unstructured textual data including: defining and selecting static attributes and dynamic attribute from structured data, embedding static and dynamic views of the selected corresponding attributes in an annotated document, linking the unstructured textual data with the structured data using the defined static and dynamic attributes, populating an annotated document structure of multiple annotated documents, performing semantic analysis of a query across the unstructured textual data and structured data, querying the annotated document structure to provide query results satisfying static part of the query, processing static and dynamic parts of the query by querying structured data and the annotated document structure, as appropriate, and providing a combined query processing result satisfying the dynamic and static part the query. Other embodiments are also disclosed.
摘要:
Presenting system and device conditions and purchasing options for components compatible with hardware devices of a computer system. In one aspect, an operating system determines the identity of a hardware device in communication with the operating system, communicates over a network to receive current purchasing information related to the hardware device, and displays components that can be selected for purchase and used with the hardware device. Another aspect provides a selectable user interface control for display in a graphical user interface that indicates a new operating condition of the computer system, different from a prior operating condition, by displaying a different appearance of the control. One embodiment has a new operating condition occurring when a component of a hardware device is within a predetermined threshold of requiring replacement, refilling, or supplementation.
