  • Patent number: 12122008
    Abstract: The invention relates to the field of milling, specifically a point position layout optimization method and a follow-up support head in mirror milling. It features an annular and linear sliding module to design a support head with adjustable support points. A corresponding layout optimization method is developed, starting with a coupled vibration model of the machining process. A layout optimization model is then created, with the quantity of support points and the support radius as decision variables. The goal is to minimize vibration amplitude and root mean square, constrained by structural interference and boundary conditions. The solution is achieved using a particle swarm optimization algorithm, supplemented by parameter scanning and a penalty function strategy. This invention addresses the limitations of existing single support point layouts for the mirror milling of various large thin-walled workpieces.

  • Publication number: 20240240548
    Abstract: The present disclosure provides a self-generating heat process for in-situ converting medium-low mature and organic-rich shale, and relates to the field of in-situ mining of medium-low mature shale rich in organic matter, the self-generating heat process mainly comprises the following steps: locally preheating the vincinity of an injection well of medium-low mature and organic-rich shale formation with well-reformed reservoir and injecting ambient temperature air into the preheated formation to excite and establish a chemical reaction zone composed of a residue zone, an autogenous heat zone, a thermal cracking zone and a preheating zone. Heat is released by oxidation reaction of residues generated after kerogen thermal cracking, so as to realize convection heating of medium-low mature and organic-rich shale formation. Oil and gas products generated from kerogen thermal cracking enter production wells through fractures and are lifted to the ground surface.

  • Publication number: 20240211297
    Abstract: A method for a primary virtual machine (VM) to schedule a sibling VM task executed by a hypervisor. Upon request of the sibling VM, the hypervisor creates a sibling task which includes a hypervisor ID. The hypervisor ID is then communicated to the primary VM. Subsequently, the primary VM creates a broker task, identified by its broker ID, and based on the received hypervisor ID for the sibling VM task. The primary VM then communicates to the hypervisor a mapping of the broker ID to the corresponding hypervisor ID. Finally, the primary VM executes the broker task when instructed by a scheduler of the primary VM. The broker task then triggers the hypervisor to run the corresponding sibling task based on the mapping.
