A method includes receiving (404) data defining user actions associated with an AR/VR space. The method also includes translating (410) the user actions into associated commands and identifying (412) associations of the commands with visual objects in the AR/VR space. The method further includes aggregating (414) the commands, the associations of the commands with the visual objects, and an AR/VR environment setup into at least one file (120) and transmitting or storing (416) the file(s). Another method includes receiving (504) at least one file (120) containing commands, associations of the commands with visual objects in an AR/VR space, and an AR/VR environment setup. The other method also includes translating (508) the commands into associated user actions and recreating or causing a user device (204, 206, 208) to recreate (512-514) (i) the AR/VR space containing the visual objects based on the AR/VR environment setup and (ii) the user actions in the AR/VR space based on the associations of the commands with the visual objects.

Described herein are methods and systems for liquefying natural gas using an open-loop natural gas refrigeration cycle; coil wound heat exchanger units suitable for cooling one or more feed streams, such as for example one or more natural gas feed streams, via indirect heat exchange with a gaseous refrigerant; and methods and systems for removing heavy components from a natural gas prior to liquefying the natural gas using an open-loop natural gas refrigeration cycle.

Various embodiments described herein relate to providing and/or employing a system and a method for tracking emissions in a facility. In this regard, inventory data associated with at least one of a product and a process is collected from a plurality of data sources. As a result, a Product Carbon Footprint (PCF) value associated with the at least one of the product and the process is determined based on the inventory data and corresponding emission factors. Based on at least one change in parameters of the inventory data, the inventory data is updated in real-time. As a result, an updated PCF value is determined in real-time based on the updated inventory data. Accordingly, the updated PCF value is displayed via a user interface of a display device.

Approaches for efficiently and accurately resolving user queries related to a particular premises are described. According to one example, one or more data repositories, associated with the premises, that are to be searched to respond to a user query are identified using a query resolution model. Further, a processing route is determined to search and analyse the one or more data repositories. The user query and the one or more data repositories are then parsed, by the query resolution model, in accordance with the processing route to retrieve and process relevant data from each of the one or more data repositories for generating a final response to the user query. The relevant data may have a context similar to the context of the user query.

A system includes processor(s) configured to: receive a rate of change process variable, a rate of change high limit, and a rate of change low limit for an integrating control variable of a process from a process controller used to control the process; determine whether a constraint violation has occurred on integrating control variable of process based on rate of change process variable, rate of change high limit, and rate of change low limit; perform gain adaptive stepping on integrating control variable using rate of change process variable, rate of change high limit, and rate of change low limit; determine at least a first set point for at least a first manipulated variable corresponding to the integrating control variable based on the gain adaptive stepping previously performed; and output the at least the first set point for the at least the first manipulated variable to adjust the process.
