  • Patent number: 8248419
    Abstract: A system for interactive computer graphics enables generation of Bezier curves from a series of points based on the relative position of successive points in the series. For example, for successive points in a series, point A, point B, and point C are successive points in the series of points, and wherein a control point corresponding to point B and associated with the segment AB is determined by the equation B+RA*(RA*(B?C)+RC*(A?B)), and a control point corresponding to point B and associated with the segment BC is determined by the equation PBBC=B+RC*(RA*(C?B)+RC*(B?A)), where RA=|AB|/(|AB|+|BC|), and RC=|BC|/(|AB|+|BC|).

    Abstract: A nuclear reactor fueling plan evaluating system and method in which reactor shutdown margin evaluation are performed quickly and accurately. A fueling procedure formulating part and an input setting part having databases are included. A maximum worth control rod candidate selecting part having a control rod worth calculating means which inputs fuel loading and control rod patterns of each fueling act, inputs a relatively simple second physics model, calculates control rod worth from the difference between the degree of subcriticality of a reactor core in a state that all control rods are inserted and the degree of subcriticality of the reactor core in a state that a single control rod is withdrawn for each fueling step, and selects a determined number of maximum worth control rod candidates. A reactor shutdown margin calculating part inputs a subdivided first physics model and calculates reactor shutdown margin for each maximum worth control rod candidate.

  • Publication number: 20100199468
    Abstract: In an attachment structure, a vehicle-mounted electronic device is attached to a receiving box using an adjusting member for adjusting a difference between an external dimension of the electronic device and a dimension of a receiving space of the receiving box for receiving the electronic device. The adjusting member has an insertion-coupling device for insertion-coupling the adjusting member and the electronic device, and a first catch-coupling device for catch-coupling the adjusting member and the receiving box. The first catch-coupling device is an appended claw-receiving part that corresponds to a flexible claw on the receiving box, and the direction of insertion-coupling of the insertion-coupling device and the direction of catch-coupling of the first catch-coupling device are different.

    Abstract: Methods and apparatus are provided for executing processor tasks on a multi-processing system. The multi-processing system includes a plurality of sub-processing units and a main processing unit that may access a shared memory. Each sub-processing unit includes an on-chip local memory separate from the shared memory. The methods and apparatus contemplate: providing that the processor tasks be copied from the shared memory into the local memory of the sub-processing units in order to execute them, and prohibiting the execution of the processor tasks from the shared memory; and migrating at least one processor task from one of the sub-processing units to another of the sub-processing units.

  • Publication number: 20080313624
    Abstract: Methods and apparatus are provided for enhanced instruction handling in processing environments. A program reference may be associated with one or more program modules. The program modules may be loaded into local memory and information, such as code or data, may be obtained from the program modules based on the program reference. New program modules can be formed based on existing program modules. Generating direct references within a program module and avoiding indirect references between program modules can optimize the new program modules. A program module may be preloaded in the local memory based upon an insertion point. The insertion point can be determined statistically. The invention is particularly beneficial for multiprocessor systems having limited amounts of memory.

  • Patent number: 7398368
    Abstract: Atomic operations may be implemented on a processor system having a main memory and two or more processors including a power processor element (PPE) and a synergistic processor element (SPE) that operate on different sized register lines. A main memory address containing a primitive is divided into a parity byte and two or more portions, wherein the parity byte includes at least one bit. A value of the parity byte determines which of the two or more portions is a valid portion and which of them is an invalid portion. The primitive is of a memory size that is larger than a maximum size for atomic operation with the PPE and less than or equal to a maximum size for atomic operation with the SPE. Read with reservation and conditional write instructions are used by both the PPE and SPE to access or update a value of the atomic.
