A method for recognizing text in graphical drawings includes creating a binarized representation of a drawing to form an electronic image of pixels. The image is discriminated between text regions and lines in the image by grouping pixels into blocks and comparing blocks with a predetermined format to identify text regions. The lines that remain in the text regions are removed to create text only regions. The text is recognized in the text only regions.

A method to manage operating costs of a combined cooling heating and power (CCHP) plant that includes converting complex models of underlying components of the plant into simplified models (S101), performing an optimization that uses the simplified models as constraints of the optimization to output at least one decision variable (S102), and adjusting controls of the plant based on one or more of the output decision variables (S103).

Systems and methods are provided for generating and publishing electronic spare parts catalogs that support electronic business processes for managing and selling spare parts for complex machines and systems, such as gas turbines. Automated systems and methods for generating electronic catalogs of spare parts employ an extensible, template-based framework to extract and integrate catalog content (static and/or real-time spare parts data) from various backend business information systems and data sources.
摘要:
Methods are disclosed that teach two simulators used with demand response management systems. The first simulator generates load patterns from historical customer consumption data and generates customer loads from the generated load patterns. The second simulator generates customer response to changing electricity prices using an econometric characterization of the customer response.

A statistical technique is used to estimate the status of switching devices (such as circuit breakers, isolator switches and fuses) in distribution networks, using scares (i.e., limited or non-redundant) measurements. Using expected values of power consumption, and their variance, the confidence level of identifying the correct topology, or the current status of switching devices, is calculated using any given configuration of real time measurements. Different topologies are then compared in order to select the most likely topology at the prevailing time. The measurements are assumed as normally distributed random variables, and the maximum likelihood principle or a support vector machine is applied.

For generating a word space, manual thresholding of word scores is used. Rather than requiring the user to select the threshold arbitrarily or review each word, the user is iteratively requested to indicate the relevance of a given word. Words with greater or lesser scores are labeled in the same way depending upon the response. For determining the relationship between named entities, Latent Dirichlet Allocation (LDA) is performed on text associated with the name entities rather than on an entire document. LDA for relationship mining may include context information and/or supervised learning.

A method for navigating digital medical images includes providing a digitized patient medical image of a structure of interest in a patient, using a pre-trained classifier to segment the structure of interest from the image, creating links from the structure of interest to a corresponding structure in an anatomical atlas, receiving a query to view the structure of interest, parsing the query to identify one or more keywords from noun phrases in the query, mapping a keyword to a corresponding structure in the anatomical atlas, wherein the anatomical atlas structure is associated with a link to the corresponding structure in the patient image, and following the link to display said patient structure of interest.
摘要:
Systems and methods are provided for implementing electronic business applications for managing and selling spare parts, wherein electronic catalogs of spare parts are used to present static and/or real-time spare parts data from disparate backend data sources in a uniform, integrated manner, and wherein business logic programs are provided to support transaction activities using the electronic catalogs of spare parts, such as navigating the catalog content, and retrieving static and/or real-time spare parts data and initiating spare parts sales with the backend business information systems and spare parts data source.
摘要:
Document processing and understanding can be important for a variety of applications such as office automation, creation of electronic manuals, online documentation and annotation, etc. The first step towards this process can involve the decomposition of a page into separate units describing the text, graphics, pictures etc. Towards that end, a method of page decomposition comprises segmenting an image into a plurality of blocks according to an amount of information contained in each block, classifying each block according to a corresponding frequency spectrum, and refining a classification of each block.
摘要:
A system and method for using heterogeneous data from multiple healthcare information sources in a medical decision support system is disclosed. Each healthcare information system stores medical data using a different local schema. The medical decision support system provides responses to user queries. A query is received from a user that is generated in a standardized global schema. The query includes information from medical ontologies. Database queries are generated from the user queries that use the medical ontologies to generate constraints in the queries. The medical ontologies are also used to infer database queries. The generated query is translated into multiple queries for the multiple healthcare systems wherein each query is in the local schema of the healthcare information system that is being queried. Each database query is transmitted to one of the healthcare information systems based on the local schema of the particular query. Data is collected from each of the queried healthcare information system and analyzed. A query response is formulated for the user
