  • Efficient blasting method for similar cutting in rock tunnel
    Patent number: 11976914
    Abstract: An efficient blasting method for similar cutting in a rock tunnel is provided, which relates to the technical field of rock tunneling. The method includes the following steps: drilling: drilling central holes, lower cutting holes, upper cutting holes, auxiliary holes and peripheral holes in a cross section area for tunnel construction; filling explosives: filling explosives into the central holes, the lower cutting holes, the upper cutting holes, the auxiliary holes and the peripheral holes; and blasting: blasting following blast holes in turn to complete full-face one-time blasting in a millisecond delay blasting mode. The method is applicable for construction scenes of drilling and blasting methods.

  • Optimizing memory sharing in a virtualized computer system with address space layout randomization (ASLR) enabled in guest operating systems wherein said ASLR is enable during initialization of a virtual machine, in a group, when no other virtual machines are active in said group
    Patent number: 10747563
    Abstract: Systems and techniques are described for optimizing memory sharing. A described technique includes grouping virtual machines (VMs) into groups including a first group; initializing a first VM in the first group, wherein initializing the first VM includes identifying, for each of one or more first memory pages for the first VM, a respective base address for storing the first memory page using an address randomization technique, and storing, for each of the one or more first memory pages, data associating the first memory page with the respective base address for the first group, and initializing a second VM while the first VM is active, wherein initializing the second VM includes determining that the second VM is a member of the first group, and in response, storing one or more second memory pages for the second VM using the respective base addresses stored for the first group.
