Abstract: A computer implemented system and process to determine a model for a domain includes identifying a schema that defines a possible causal element of a particular type of behavior. One or more concepts are determined, as well as one or more sub-concepts for each concept, where each concept and sub-concept are associated with a logical relationship. Multiple models are determined from the one or more concepts and the one or more sub-concepts. The multiple models may be calibrated using representative data collected from a real-world source. An optimal model is determined amongst a plurality of calibrated models.

Abstract: A downhole tool configured for inclusion in a drill string, typically as part of a bottom hole assembly. The downhole tool configured to improve passage of the drill string through a borehole. Additionally, the downhole tool is suitable for use in a method for improving passage of a drill string through a borehole.

Abstract: A downhole tool comprises a tool housing defining a flow passage therethrough from a first to a second end thereof. A poppet is axially movable on a poppet mandrel positioned in the tool housing. The poppet mandrel has at least one outlet port defined therein. A pilot valve is rotatable about the poppet mandrel. Rotation of the pilot valve opens and closes the at least one outlet port in the poppet mandrel to permit and block flow therethrough, and wherein the opening and closing of the at least one outlet port moves the poppet axially on the poppet mandrel.

Abstract: A heat sink assembly is provided for a pluggable module. The heat sink assembly includes a heat sink having a module side and an end surface that intersects the module side. The module side is configured to thermally communicate with the pluggable module. A holder extends from the end surface of the heat sink. A thermal interface material (TIM) layer extends on the module side of the heat sink. The TIM layer is configured to engage the pluggable module. The TIM layer includes an end that is engaged between the end surface and the holder of the heat sink.

Abstract: A method and system for managing a telephony connection on hold to reduce the use of resources within the telephony network and/or to allow the user on hold to place their telephony device into an on-hook state after they have been placed on hold. In two embodiments, a user of a telephony device who has been placed on hold can initiate a Smart Hold whereby their telephony device can be placed in an on-hook state while on hold and the user will be signaled when the call is to be removed from hold. This allows the user to perform other activities while a Smart Hold has been implemented, without the need to keep a telephone handset to their car, for example. The freeing up of local loop resources can also be achieved. In another embodiment, the Smart Hold can be initiated by either party to a connection without requiring cooperation of the other party. In some embodiments, no toll charges or the like will be incurred while the Smart Hold is in effect.
