Abstract: An interactive recommendation system is provided. The system comprises an information generation module configured to: provide a set of information contents for outputting in an information interface, wherein each of the set of information contents is associated with an information item; receive a selection of one of the set of information contents that signals the user's interest or disinterest in an information item; determine, based on a model and history data related to prior activities of the user including a plurality of selections from the set of information contents, one or more information items to be included in recommendation information for the user; provide the recommendation information for outputting in a recommendation information interface; and update, based on the history data, the set of information contents for outputting in the information interface.

Abstract: A high-power microwave borehole fracturing device for an engineering rock mass includes a high-power microwave generator, a high-power microwave coaxial heater, a high-power low-loss microwave coaxial transmission line, and a microwave power adaptive regulation and control system. The high-power microwave generator includes a continuous wave magnetron, a permanent magnet, a waveguide excitation chamber, a coaxial circulator, a coaxial matching load, a coaxial coupling converter, a waveguide coaxial converter, and an output waveguide. The high-power microwave coaxial heater includes a microwave transmission inner conductor, a microwave transmission outer conductor, a microwave input connector, a microwave short circuit cap, and a conductor supporting cylinder. The high-power low-loss microwave coaxial transmission line includes an input end coaxial line, middle section coaxial lines, and an output end coaxial line.

Abstract: Some examples of visualizing relationships in data sets can be implemented as a method by one or more computer systems. Dimension objects and multiple measure objects are displayed adjacent to a cause region and an effect region in a user interface. Each dimension object represents an input category associated with an input quantity that contributes to a total quantity in a data set. Each measure object represents an output category associated with an output quantity based on an input category. A dimension object and a measure object can be moved into the cause region and the effect region, respectively, in response to input. From the data set, an output quantity associated with the measure object is determined based on an input quantity associated with the dimension object from the total quantity in the data set. A result representing the output quantity is displayed in the measure object.
