Patent number: 11845126Abstract: The present disclosure relates to a metal additive manufacturing extrusion mechanism for monitoring and improving mechanical properties in situ, and belongs to the technical field of metal additive manufacturing. The mechanism comprises a wire conveying unit, a composite cavity unit, a high-temperature loading unit, a temperature detecting unit, a pressure loading unit, a pressure detecting unit and an in-situ monitoring unit. Multi-stage high-temperature loading is achieved through silicon nitride heater components distributed in the piston, the outer wall of the cavity and the nozzle, and meanwhile service temperature detection is achieved through thermocouple components. Multi-stage pressurization is achieved through continuous pressure loading of the wire conveying mechanism and high-frequency pressure loading of the piston mechanism and the four-rod mechanism, and then service pressure detection is achieved through strain gauge components on the top of the piston and the inner wall of the cavity.Type: GrantFiled: December 29, 2020Date of Patent: December 19, 2023Assignee: JILIN UNIVERSITYInventors: Zhichao Ma, Shuai Tong, Dongni Liu, Weizhi Li, Shengteng Zhao, Guolin Xiao, Hairui Du

Publication number: 20230315802Abstract: A method comprises a compiler generating a MI (mixed integer) model to determine mapping decisions to map a dataflow application to hardware of a computing system to execute the application. The MI model comprises MI equations to solve by an MI solver. The MI equations include equations of an objective function corresponding to an optimization objective. The MI equations can comprise decision variables and equations and constraint variables and equations. The compiler outputs the MI model to the MI solver and invokes the MI solver to compute an MI solution comprising solutions to equations among the equations included in the MI model. The compiler receives the MI solution and generates a globally optimized mapping decision based on the MI solution. The MI solver can comprise a commercial program to solve MI linear equations. A computer program product and a computing system can implement the method.Type: ApplicationFiled: March 29, 2023Publication date: October 5, 2023Applicant: SambaNova Systems, Inc.Inventors: Junjue WANG, Blaine Burton RISTER, Zhichao MA, Zhuo CHEN, Andrew DENG, Sumti JAIRATH, Arvind Krishna SUJEETH
