  • Computation of radiating particle and wave distributions using a generalized discrete field constructed from representative ray sets
    Patent number: 10921756
    Abstract: The present system and method for simulating particles and waves is useful for calculations involving nuclear and full spectrum radiation transport, quantum particle transport, plasma transport and charged particle transport. The invention provides a mechanism for creating accurate invariants for embedding in general three-dimensional problems and describes means by which a series of simple single collision interaction finite elements can be extended to formulate a complex multi-collision finite element.
    Type: Grant

  • Mechanism employing a memory area for exchanging information between a parent process and a child process compiled during execution of the parent process or between a run time compiler process and an application process
    Patent number: 6243860
    Abstract: A computer system includes a central processing unit, a parent process for execution by the CPU, a child process for execution by the CPU, a memory accessible by the CPU, and a run time compiler. The memory includes a memory area for access by both of the parent process and the child process. The run time compiler includes a function port for invoking the compiler during execution of the parent process. A first compiler routine compiles the child process. A second compiler routine executes the child process. A calling chain employs the memory area to exchange information, such as data atoms, between the child process and the parent process.
