Publication number: 20080201703Abstract: Aspects of the present invention are directed at obtaining user feedback and causing a package of content updates to be created and distributed based on the received feedback. In accordance with one embodiment, a method is provided for creating a package that contains one or more content updates configured to change the content that is displayed by default when a program executes. More specifically, the method includes obtaining input that describes one or more content updates. In this regard, the input received may include the user-defined content that will be displayed when the program executes and the identity of the content displayed by default. Then, the method assembles selected content updates into a package that is suitable for transmission over a network connection. When the package is assembled, processing is provided that allows the content updates in the package to be implemented on a remote computing device.Type: ApplicationFiled: February 15, 2007Publication date: August 21, 2008Applicant: Microsoft CorporationInventors: Cameron B.

Patent number: 7366716Abstract: Systems and methodologies that split a table into a plurality of sub-tables, and vertical partitions. By analyzing an associated work load to determine frequently referenced columns, the subject invention supplies a compromise among various vertical partitioning strategies (e.g., candidate selection for table spilt) via a merging act, such that the table is split optimally for the work load taken as a whole Accordingly, an incoming query can optimally reference only required columns.Type: GrantFiled: May 6, 2005Date of Patent: April 29, 2008Assignee: Microsoft CorporationInventors: Sanjay Agrawal, Vivek R.

Patent number: 7363301Abstract: Aggregation queries are performed by first identifying outlier values, aggregating the outlier values, and sampling the remaining data after pruning the outlier values. The sampled data is extrapolated and added to the aggregated outlier values to provide an estimate for each aggregation query. Outlier values are identified by selecting values outside of a selected sliding window of data having the lowest variance. An index is created for the outlier values. The outlier data is removed from the window of data, and separately aggregated. The remaining data without the outliers is then sampled to provide a statistically relevant sample that is then aggregated and extrapolated to provide an estimate for the remaining data. This sampled estimate is combined with the outlier aggregate to form an estimate for the entire set of data.Type: GrantFiled: October 7, 2005Date of Patent: April 22, 2008Assignee: Microsoft CorporationInventors: Surajit Chaudhuri, Vivek R.

Patent number: 7287020Abstract: This disclosure describes leveraging workload information associated with executed database queries for estimating the result of a current database query. The workload information is analyzed to determine the usage of tuples in a database during query execution, such as how often a tuple is accessed and the number of different queries that accessed the tuple. A tuple is assigned a weight value that is based on the analyzed workload information. The particular tuples sampled for estimating a result for the current query is based on each tuple's weight value. The workload information may also be leveraged to generate an outlier index that identifies outlier tuples associated with the executed queries or that identifies outlier tuples associated with particular queries that are executed more frequently than other queries. The result for the current query can also be estimated using the sampled values along with the outlier tuples from the outlier index.Type: GrantFiled: January 12, 2001Date of Patent: October 23, 2007Assignee: Microsoft CorporationInventors: Surajit Chaudhuri, Vivek R.

Outlier values are identified by selecting values outside of a selected sliding window of data having the lowest variance. An index is created for the outlier values.

The remaining data without the outliers is then sampled in one of many known ways to provide a statistically relevant sample that is then aggregated and extrapolated to provide an estimate for the remaining data. This sampled estimate is combined with the outlier aggregate to form an estimate for the entire set of data. Further methods involve the use of weighted sampling and weighted selection of outlier values for low selectivity queries, or queries having group by.Type: GrantFiled: June 22, 2004Date of Patent: March 13, 2007Assignee: Microsoft CorporationInventors: Sarajit Chaudhuri, Vivek R.

Patent number: 6917010Abstract: The present invention includes a method for brazing of two objects or heat treatment of one object. First, object or objects to be treated are selected and initial conditions establishing a relative geometry and material characteristics are determined. Then, a first design of an optical system for directing heat energy onto the object or objects is determined. The initial conditions and first design of the optical system are then input into a optical ray-tracing computer program. The program is then run to produce a representative output of the heat energy input distribution to the object or objects. The geometry of the object or objects, material characteristics, and optical system design are then adjusted until an desired heat input is determined.Type: GrantFiled: April 29, 2003Date of Patent: July 12, 2005Assignee: The Regents of the University of CaliforniaInventors: John O.

Patent number: 6736963Abstract: Economical processes are disclosed for the production of fuels of reduced sulfur content from a feedstock, typically derived from natural petroleum, wherein the feedstock is comprised of limited amounts of sulfur-containing organic compounds as unwanted impurities. The processes involve an integrated, multiple stage system for converting these impurities to higher boiling products by alkylation and removing the higher boiling products by fractional distillation. Advantageously, the processes include selective hydrogenation of the high-boiling fraction whereby the incorporation of hydrogen into hydrocarbon compounds, sulfur-containing organic compounds, and/or nitrogen-containing organic compounds assists by hydrogenation removal of sulfur and/or nitrogen. Products can be used directly as transportation fuels and/or blending components to provide, for example, more suitable components for blending into fuels which are more friendly to the environment.Type: GrantFiled: July 31, 2001Date of Patent: May 18, 2004Assignee: BP Corporation North America Inc.Inventors: Vivek R.

Patent number: 6602405Abstract: A product of reduced sulfur content is produced from an olefin-containing hydrocarbon feedstock which includes sulfur-containing impurities. The feedstock is contacted with an olefin-modification catalyst in a reaction zone under conditions which are effective to produce an intermediate product which has a reduced amount of olefinic unsaturation relative to that of the feedstock as measured by bromine number. The intermediate product is then contacted with a hydrodesulfurization catalyst in the presence of hydrogen under conditions which are effective to convert at least a portion of its sulfur-containing impurities to hydrogen sulfide.Type: GrantFiled: January 21, 2000Date of Patent: August 5, 2003Assignee: BP Corporation North America Inc.Inventors: Vivek R.
