Abstract: Nodes of a tree are dynamically generated. A user may specify that a node should have a separate child node for each unique value that occurs in a particular column of a relational table. A user may specify that a node should have a separate child node for each range of values in a user-specified set of ranges. Child nodes of a particular node may be dynamically determined and displayed by querying one or more relational tables for records that satisfy all of the criteria that are implied by that particular node and that particular node's parents. As a result of the foregoing techniques, users are not forced to create a tree node-by-node; instead, users can specify criteria based on which a whole level of nodes should be created, and a whole level of nodes may be added to a tree based on those criteria.

Abstract: A constraint solver for solving a constraint satisfaction problem network that comprises a plurality of nodes and a plurality of constraints.

Abstract: According to an aspect of the present invention, nodes for hosting of new virtual machines (VM) are selected according to approaches designed to reduce power consumption in a grid. In an embodiment, the approaches are designed to facilitate the possibility of freeing one or more nodes from hosting VMs to power down the nodes, thereby reducing power consumption. Thus, an example approach is based on provisioning a new VM on a node which currently (immediately prior to provisioning) has the maximum resource consumption. Another example approach is based on provisioning a new VM on a node which currently has small-sized VMs in terms of resource requirements. In yet another embodiment, the approach is based on provisioning a new VM on a node located in a geographical area having low power tariffs.

Abstract: An 18n-pulse rectifier for AC drive systems having a separate DC bus for each output phase is provided, where n=any positive integer. The rectifier uses three separate phase rectifiers, one for each output phase of a transformer, each comprised of 2n six-pulse diode bridges connected in series or parallel. Each phase rectifier may be supplied with n unique sets of phase inputs from a transformer secondary winding. In some configurations, the n sets of inputs provided to each rectifier are separated by 60/n degrees of phase (when n is greater than 1), while the corresponding inputs to neighboring rectifiers are separated by 20/n degrees of phase. In a 36-pulse example, the phase offsets for the inputs provided to the rectifiers may be ?25° and +5° from the transformer primary winding (for the first rectifier), ?15° and +15° from the primary winding (for the second rectifier) and ?5° and +25° from the primary winding (for the third rectifier).

Abstract: A method, system, and computer program product provides improved performance for queries on local partitioned indexes. A method of performing a database query comprises receiving a query of spatial data in a database, the database comprising at least one partitioned spatial index, obtaining metadata relating to all partitions of the spatial index using array-fetching techniques, determining, for each partition, whether the partition is relevant to the query by comparing with “footprint” (root_mbr) information stored in the metadata for the partition, and processing the query on each relevant partition.

Abstract: An XML Extractor that extracts XML data from streamed input based on registered XPaths is provided. XPaths and associated content handlers instances are registered at runtime with the XML Extractor. The XML Extractor receives streaming input that represents XML data at a stream-based parser, and evaluates the received input against the registered XPaths expression. In response to detecting that the received streaming input includes an XPath that matches a registered XPath expression, the XML Extractor generates output to the content handler associated with the matching registered XPath expression.

Abstract: Techniques are provided for delaying evaluation of expensive expressions in a query. Expensive expressions in the query are established by cost information or by looking up a list of known expensive expressions for a match. After an execution plan is determined by using the early evaluation technique, one or more equivalent execution plans is established. The one or more equivalent execution plans may include both a type of execution plans that delay evaluation of expensive expressions and a type of execution plans that do not. In addition, the one or more equivalent execution plans may include both parallelized and non-parallelized alternatives to the execution plan identified by the early evaluation technique. Finally, based on a set of criteria, which may include comparing cost information among all the equivalent execution plans generated thus far, the best execution plan is chosen for the query.

Abstract: Under automated alternate plan analysis, a query optimizer generates candidate execution plans. The candidate execution plans are selected as alternate execution plans for the query and execution. Output describing characteristics of each alternate execution plan and/or its execution is generated and/or compared. From this information, it may be determined, for example, whether results returned by any of the alternate execution plans are the same and whether the least cost execution plan is actually the most efficiently executed.

Abstract: A user uses a graphical user interface to configure a search process. One or more set up pages may be output to the user to allow the search process to be configured. Once the search process is defined, a graphical user interface is generated that provides the search process. A searcher can then use the interface to perform searches. A search page is provided that includes fields that were defined. When a search term is received, a search is performed according to a search definition. The search results are then returned according to how the search results were configured. For example, the search results may be returned in a stepped fashion. Additionally, a quick create option is provided on the search result page. This allows a user to create an entry that is classified according to the search definition for the field that was searched.
