Systems and methods for generating a beam model for radiotherapy treatment planning are discussed. An exemplary system includes a memory to store a trained deep learning model, and a processor circuit to generate a beam model. The deep learning model can be trained to establish a relationship between machine scanning data and values of beam model parameters, and validated for accuracy. The processor circuit can receive machine scanning data indicative of a configuration or an operation status of the radiation therapy device, apply the machine scanning data to the trained deep learning model to determine values for the beam model parameters, and generate a beam model based on the determined values of the plurality of beam model parameters. The beam model may be provided to a user, or a treatment planning system.

Automatic beam modeling based on deep learning

Systems and methods for displaying and associating context images with zones or devices of a security system or a home automation system are provided. Such systems and methods may include associating each of a plurality of zones or devices of the security system or the home automation system with a respective context image and displaying the respective context image for one of the plurality of zones or devices in response to a user interface of the security system or the home automation system receiving user input.

Systems and methods for displaying and associating context images with zones of a security system

A non-toxic coolant/lubricant suspension is provided which is specifically designed for use in extremely high-load, high-stress machine operations, such as broaching. The composition of this coolant/lubricant includes about 1 to 15 wt % of molybdenum disulfide (MoS.sub.2) powder; about 1 to 7 wt % of soap flakes; about 6 to 12 wt % of a liquid polytetrafluoroethylene suspension; and about 66 to 92 wt % water. The liquid polytetrafluoroethylene component, which is a water-based suspension of polytetrafluoroethylene, serves as a replacement for toxic CCl.sub.4, which has been used to increase lubricity in coolant/lubricants comprising molybdenum disulfide. The replacement of CCl.sub.4 with liquid polytetrafluoroethylene in the present composition results in a non-toxic but still highly effective coolant/lubricant. The coolant/lubricant is a stable suspension, which permits it to be used in recirculating systems in which the coolant/lubricant is recovered, filtered, and re-directed onto the broaching tool and/or workpiece.

Coolant/lubricant for machine operations

A non-toxic coolant/lubricant is provided which is specifically designed for use in extremely high-load, high-stress machine operations, such as broaching. The composition of this coolant/lubricant includes about 8 to 15 wt % of molybdenum disulfide (MoS.sub.2) powder; about 2 to 6.6 wt % of soap flakes; about 6 to 12 wt % of a liquid polytetrafluoroethylene suspension; and about 66.4 to 84 wt % water. The liquid polytetrafluoroethylene component, which is a water-based suspension of polytetrafluoroethylene, serves as a replacement for toxic CCl.sub.4, which has been used to increase lubricity in coolant/lubricants comprising molybdenum disulfide. The replacement of CCl.sub.4 with liquid polytetrafluoroethylene in the present composition results in a non-toxic but still highly effective coolant/lubricant.
