  • Patent number: 11132478
    Abstract: Methods for combinatorial choice in topology optimization are disclosed. In one embodiment, a method of performing combinatorial choice in a non-linear programming problem for designing a structure includes establishing, by one or more processors, a set of K variables, wherein the set of K variables defines an K-dimensional unit cube in a normal coordinate system. The K-dimensional unit cube includes a plurality of desired vertices representing a plurality of desired combinations that satisfy a constraint and a plurality of undesired vertices representing a plurality of undesired combinations that do not satisfy the constraint. The method further includes transforming the K-dimensional unit cube into a transformed shape in a transformed coordinate system using a shape function. Values of the set of K variables cannot have a combination represented by the plurality of undesired combinations.

  • Patent number: 8553879
    Abstract: Provided is a content transmission device 310 that can reduce failure of content key confirmation processing during special playback such as fast-forwarding and fast-rewinding. A key management unit 312 generates or updates a key parameter, and stores therein the generated or updated key parameter. The key management unit 312 receives a key parameter from the content reception device 340, and calculates a difference between the key parameter stored therein and the received key parameter. By using the calculated difference, a transmission control unit 313 judges whether or not to change a transmission speed at which an encrypted content portion is to be transmitted, and depending on a result of the judgment, selects one of transmission speeds and transmits the encrypted content portion in accordance with the selected transmission speed.

  • Publication number: 20130094941
    Abstract: Variable displacement compressor is provided with a displacement control valve (2) that can change an opening degree of supplying passage (44, 46) between a valve seat (VS) and a valve body (VB), thereby changing the pressure in a crank chamber (9). The displacement control valve (2) is accommodated within a control valve chamber (5c) in a rear housing (5) and fixed in place by means of a circlip (50). A cutout (50g) is formed between the displacement control valve (2) and the circlip (50) and/or between the circlip (50) and the rear housing (5). A clearance (C) formed by the cutout (50g) and the like inhibits the transmission of vibrations caused by impacts between the valve seat (VS) and the valve body (VB). This makes the variable displacement compressor quiet, reduces costs by obviating the need for additional components, and results in excellent durability.
