Abstract: A method and device are provided for purifying and recycling water vapor from a coal drying process. Included are a temperature-lowering and dehumidifying process, a flash distillation stripping process, and a vacuum condensing process. A condensing tower receives a temperature-lowered exhaust gas with high humidity from a cooling tube and a condensed water of 5˜60° C. from a flash distillation tank, allowing the exhaust gas and the condensed water to contact each other in a vapor-liquid reverse manner, to lower the temperature and dehumidify the exhaust gas. The flash distillation tank performs a vacuum flash distillation to the condensing water pumped therein from the condensing tower. Water vapor of 5˜60° C. evaporated through flash distillation in the flash distillation tank enters into the demisting washer to be dehumidified and then is condensed. The condensed water in the vapor condenser is transferred into a recycled water tank. Non-condensable gas is discharged out.

Abstract: Existing program code, which is executable on one or more computers forming part of a distributed computer system, is analyzed. The analysis identifies log output instructions present in the program code. Log output instructions are those statements or other code that generate log messages related to service requests processed by the program code. A log model is generated using the analysis. The log model is representative of causal relationships among service requests defined by the program code. The log model can then be applied to logs containing log messages generated by execution of the program code, during its normal operation, to group log messages for improved analysis, including visualization, of the performance and behaviour of the distributed computer system.

Abstract: Providing for a two-terminal memory cell having intrinsic current limiting characteristic is described herein. By way of example, the two-terminal memory cell can comprise a particle donor layer having a moderate resistivity, comprised of unstable or partially unstable metal compounds. The metal compounds can be selected to release metal atoms in response to an external stimulus (e.g., an electric field, a voltage, a current, heat, etc.) into an electrically-resistive switching medium, which is at least in part permeable to drift or diffusion of the metal atoms. The metal atoms form a thin filament through the switching medium, switching the memory cell to a conductive state. The moderate resistivity of the particle donor layer in conjunction with the thin filament can result in an intrinsic resistance to current through the memory cell at voltages above a restriction voltage, protecting the memory cell from excessive current.
