Abstract: A method, apparatus, system, article of manufacture, and computer program product provide the ability to utilize a degree of freedom (DOF) for a construction. In a preparation phase, a graph structure is constructed from a construction model that transforms construction primitives into graph primitives. In a search phase, all compact sub-graphs of the graph structure are identified. In a counting phase, a DOF is calculated for each compact sub-graph and adjusted based on interactions between the compact sub-graphs. In an internal DOF searching phase, an internal DOF is computed for each compact sub-graph and used to determine and solve overconstrained sub-graphs. A determination regarding whether a structure of the construction model can be modified based on the DOF and internal DOF is output.

Abstract: Systems, methods, and instructions encoded in a computer-readable medium can perform operations related to simulating subterranean fracture propagation. A subterranean formation model representing rock blocks of a subterranean formation is received. The subterranean formation model is used to predict a response of each rock block to one or more forces acting on the rock block during an injection treatment for the subterranean formation.

Abstract: In a network that includes static bandwidth and dynamic bandwidth links, traffic flow at the OSI network layer is simulated at a traffic-flow level at interfaces to fixed bandwidth links, and simulated at a discrete-packet level at interfaces to dynamic bandwidth links. The resultant discrete-packet reception events at the receiving interface(s) of the dynamic bandwidth link are processed to determine the effective bandwidth/throughput of the link, as well as the allocation of this bandwidth among the individual flows through the link. The discrete-packet level receptions are used to reconstruct the parameters of the traffic flow at the network layer of the receiving interface, and this determined traffic flow is simulated accordingly at the next link, depending upon whether the next link is a static or dynamic bandwidth link.

Abstract: Described herein are systems and methods for configuring a BMS. In general terms, the present technology is focused on approaches for arranging and modeling building information data, particularly in terms of equipment categories and relationships between pieces of equipment, for example in the context of an HVAC system. This is advantageous in the sense that the likes of visualization, application creation, and reporting are able to be significantly streamlined. Various embodiments make use of an “equipment model”, being a model which defines items for each piece of equipment in a building system based on predefined standards, thus allowing for predictable descriptions (for example in terms of data points and relationships). Some embodiments combine this with a facility model, which describes a building in spatial terms.
