Abstract: A computer-implemented method includes receiving a graph pattern matching query, determining that the query is an unbounded recursive path query (RPQ), and initializing an unbounded root vertex match operator (UBRM) using a starting vertex as input to the UBRM; the UBRM is configured to compute multiple hops between vertices on the graph. The method also includes performing a first reachability search using the UBRM; the UBRM traverses the graph to identify all vertices reachable from the starting vertex. The method further includes generating first level vertices of a path pattern that computes the RPQ; and adding the first level vertices to a first level context for processing by a successor match operator; the successor match operator comprises an unbounded intermediate neighbor match operator (UBNM), the UBNM is configured to compute multiple hops between vertices on the graph and to identify neighbors for each of the first level vertices.

Abstract: The present disclosure relates to a system for implementing an immersive Cave Automatic Virtual Environment (CAVE), wherein the proposed system includes a master server engine that is configured to enable multi-side electronic visual displays, and further includes a real-time motion tracking engine that is operatively coupled with the master server engine. The motion tracking engine can be configured to, in real-time, determine cyber-physical position data of at least one motion tracked object across X, Y, and Z coordinates using one or more motion track sensors that are operatively coupled to said real-time motion tracking engine, and enable generation of tracking data of said at least one tracked object based on said cyber-physical position data, said tracking data being used to integrate and visualize said at least one tracked object in said CAVE.
