摘要:
Interoperability is enabled between participants in a network by determining values associated with a value metric defined for at least a portion of the network. Information flow is directed between two or more of the participants based at least in part on semantic models corresponding to the participants and on the values associated with the value metric. The semantic models may define interactions between the participants and define at least a portion of information produced or consumed by the participants. The determination of the values and the direction of the information flow may be performed multiple times in order to modify the one or more value metrics. The direction of information flow may allow participants to be deleted from the network, may allow participants to be added to the network, or may allow behavior of the participants to be modified.

An object tracking technique is provided which, given: (i) a potentially large data set; (ii) a set of dimensions along which the data has been ordered; and (iii) a set of functions for measuring the similarity between data elements, a set of objects are produced. Each of these objects is defined by a list of data elements. Each of the data elements on this list contains the probability that the data element is part of the object. The method produces these lists via an adaptive, knowledge-based search function which directs the search for high-probability data elements. This serves to reduce the number of data element combinations evaluated while preserving the most flexibility in defining the associations of data elements which comprise an object.

Methods and apparatus are provided for rewriting queries during a database query processing operation to include auxiliary attributes not included in the original query, thus improving processing efficiency. For example, in one aspect of the invention, a technique for rewriting a query in a query processing operation includes the following steps. First, the query is processed in accordance with at least a portion of a data set, producing query results. Second, data attributes from the query results are analyzed. Finally, at least one new predicate from at least one auxiliary data attribute is appended on the query.

摘要:
An electronic device may have components such as button members, display cover glass layers, structures associated with connector ports, and other components. The components may have transparent and opaque structures. The transparent structures may be formed on top of the opaque structures. The transparent structures may have peripheral edges through which light may pass. To help prevent the appearance of the components from becoming degraded by the presence of dirt, at least some of the edge portions of the transparent structures may be covered with an opaque covering material. The opaque covering material may be formed from paint or sidewall structures that are formed as an integral part of the opaque structures.

A seal is disclosed for retrofitting to an existing railroad hopper car having opposing sidewalls and at least one trough extending between the opposing sidewalls. The seal includes a first member configured to mate against a surface of a trough adjacent a sidewall, the first member including a first edge having angled sections corresponding to angled sections of where the sidewall meets the trough, and a second member integral with the first member and extending substantially upright from the first edge of the first member, the second member configured to mate against a surface of the sidewall adjacent the trough, wherein the second member is angled relative to the first member at each of the angled sections corresponding to angled sections of the sidewall adjacent the trough.

Methods for non-invasive prenatal ploidy calling are disclosed herein. Methods for determining the ploidy status of a chromosome in a gestating fetus from genotypic data measured from a sample of DNA from the mother of the fetus and from the fetus, and from genotypic data from the mother and optionally also from the father are disclosed herein. The ploidy state is determined by using a joint distribution model to create a set of expected allele distributions for different possible fetal ploidy states given the parental genotypic data, and comparing the expected allelic distributions to the pattern of measured allelic distributions measured in the mixed sample, and choosing the ploidy state whose expected allelic distribution pattern most closely matches the observed allelic distribution pattern. In an embodiment, the mixed sample of DNA may be preferentially enriched at a plurality of polymorphic loci in a way that minimizes the allelic bias.

Methods and apparatuses are disclosed that allow an electronic device to autonomously adapt one or more user alerts of the electronic device. For example, some embodiments may include a method for operating a haptic device including driving a haptic device using a control signal, measuring a frequency related to the operation of the haptic device and comparing the measured frequency with a target frequency. A control signal is adjusted based on the comparison to drive the haptic device to the target frequency.
