20150354336 | CONTROL PARAMETER DETERMINATION IN STEAM ASSISTED GRAVITY DRAINAGE OIL DRILLING - Drilling data including a plurality of values measured for each of a plurality of drilling parameters is received. An objective function that maximizes production of a material produced by a production operation, minimizes water usage by the production operation, and minimizes a sub-cool temperature of the material is determined using the received drilling data. An association rule that defines a range of values for a control parameter of the plurality of drilling parameters that is selected based on a value of a first parameter of the plurality of drilling parameters is determined using the received drilling data. Measured drilling data that indicates current control parameter values of the production operation is received. An optimal value for the control parameter is determined by executing the determined objective function with the received, measured drilling data as an input and subject to the determined association rule. The determined optimal value is output. | 12-10-2015 |

20090107312 | METHOD AND APPARATUS TO CREATE BENDS IN COMPOSITE PANELS - A method and apparatus for forming a bend in composite panel. In one advantageous embodiment, a method is used to form a bend in a composite panel. An angle and a radius bend are identified for the bend. A location of the bend in the composite panel is identified. A slot is cut having a curved flange in the composite panel at the identified location in a single pass through the composite panel with a tool, wherein the curved flange has a shape with a bend allowance width and a bend slot width. The bend allowance width is BA=2π*A/360, wherein BA is the bend allowance width, R is a corner radius, and A is a bend angle. The bend slot width is BS=BA−2K(R−T), wherein K is Tan(A/2) and T is a thickness of the composite panel. The composite panel with the slot is bent to form the bend. | 04-30-2009 |
