Abstract: A management server measures network activity of user devices to determine activities of the users associated with each user device. The management server generates digital model personas corresponding to the users based on one or more activities of the user. The management server clusters the digital model personas to generate user groups based on similar activities, and compares a first digital model persona from a first user with at least one second digital model persona.

Abstract: A network management system tests the availability of a network resource before a user performs a task with the network resource. The system measures network activity of a user performing one or more tasks. The network activity includes communication between a user device of the user and each network resource associated with a corresponding task performed by the user. The system also generates a digital model persona of the user based on the tasks performed by the user, and determines a schedule of the tasks performed the user. Each particular task is associated with a corresponding execution time for the user. The system further configures the digital model persona to test the network resource associated with each corresponding task at a testing time that is a predetermined length of time prior to the execution time for the user.

Abstract: A computer-implemented graphics system defines an object-oriented framework for describing three-dimensional (3D) graphical objects, systems, and simulations. A 3D graphical image, a system, and a simulation are implemented as a directed multi-graph that includes a plurality of components defined by nodes connected by edges. A directed multi-graph engine in a graphics computer program processes the directed multi-graphs, wherein each node in the graph performs some specific function and the edges define relationships between the nodes. There are no restrictions on node types, and thus nodes may represent graphic objects (a visual representation), rules (rule-base behavior), attributes (data that does not affect the fundamental definition of the object), properties (data that affects the fundamental definition of the object), behaviors (methods), finite state machines (a sequence of actions and states), and any other user-defined component.

Abstract: In graphics systems, objects are manipulated and placed by users. Some systems aid the user in placing objects by providing interesting points or relevant geometric data for the objects. Objects may have manipulation or behavioral constraints that limit the placement of the object with respect to other objects. Such behavioral constraints may be associated with the relevant geometric data and may be created by the interaction between two objects. Embodiments of the invention simplify or filter objects. Simplification and filtering provide a replacement or temporary object that is not as mathematically complex with fewer geometric data, attributes, and behavioral constraints. The simplification of an object evaluates the definition of the geometry of an object to obtain a simpler geometrical object that is not as complex. The filtering of an object filters the object based on varying criteria.
