K-Nearest Neighbor Temporal Aggregate Queries

query differs from spatial keyword queries in that instead of the keywords query time intervals are given, and a dynamic aggregate attribute (e.g., the count of check-ins) rather than the textual relevance is considered. Given two data sets P and Q (queries), an aggregate nearest neighbor (aNN) query [19] retrieves the points in P that have ...

Aggregate k-nearest neighbors queries in time-dependent ...

In this paper we present an algorithm for processing aggregate nearest neighbor queries in time-dependent road networks, i.e., given a road network where the travel time over an edge is time-dependent, a set of query points Q, a set of points of interest (POIs) P and an aggregate function (e.g., sum), we find the k POIs that minimize the aggregated travel time from the query points.

SQL - Subquery in Aggregate Function - Stack Overflow

Although I could have rewritten the query to use the aggregate function within the first set of parenthesis (as was previously suggested) I found it easier to save query results as a table in the database sorted in the order I wanted and then use the "Last" aggregate function to retrieve the values I wanted.

SCHEDULING AGGREGATE QUERIES IN HOP SENSOR NETWORKS

A query service works as follows: a user issues a query to a sensor network through a base station, which disseminates the query parameters to all nodes. The query service maintains a routing tree rooted at the base station. The query service supports in-network data aggregation.

Aggregate Ethernet (AE) Interface Group

Before configuring an AE interface group, you must configure its interfaces. Among the interfaces assigned to any particular aggregate group, the hardware media can differ (for example, you can mix fiber optic and copper), but the bandwidth (1Gbps, 10Gbps, 40Gbps, or 100GBps) and interface type (HA3, virtual wire, Layer 2, or Layer 3) must be the same.
