20080243459 | Optimization Using Indirect Design Coding - A method for optimizing a material structure. The method comprises the steps of encoding an initial design of the material structure to be optimized as a parameter set, subjecting the initial design to an optimization according to at least one preset criterion, using an evolutionary algorithm, terminating the optimization when a termination condition is met, and outputting data representing the optimized parameter set. The design of the material structure is encoded indirectly as a virtual DNA. | 10-02-2008 |
20090012752 | Aerodynamic Design Optimization Using Information Extracted From Analysis of Unstructured Surface Meshes - A computer-implemented method of analyzing data representing the optimization of real-world designs of physical entities according to at least one criterion. Different modifications of the design are generated by a cyclic optimization algorithm. The design data is represented by unstructured triangular surface meshes. A displacement measure representing local differences between two design modifications of the different modifications is calculated. Performance difference between the two design modifications is calculated. The performance difference is represented by at least one criterion. Sensitivity information representing correlation between the displacement measure and the performance differences is outputted. | 01-08-2009 |
20110040542 | METHOD AND SYSTEM FOR THE INTEGRATION OF FUNCTIONAL CAE DATA IN A CAD BASED STYLING PROCESS FOR INDUSTRIAL DESIGN, ESP. CARS, MOTORBIKES OR AERONAUTIC VEHICLES - Computer-assisted systems and methods for integrating aesthetic and functional design processes for real-world objects can include a computerized module for defining an aesthetic representation of a real-world object, and a computing module supplied with approximation model data of a CAE simulation module to calculate functional quality value(s) using a parametric description of the aesthetic representation as input. An interface can issue a physical signal to a user, with the physical signal communicating the quality value(s) to the user. A computerized module can change the parametric description of the aesthetic representation of the object in the aesthetic design process taking the obtained functional quality value into account. | 02-17-2011 |

20120315136 | INNER PERIPHERAL SURFACE SHAPE OF CASING OF AXIAL-FLOW COMPRESSOR - A generating line of a casing surrounding an outer periphery of vanes of a stator disposed downstream of a rotor of the axial-flow compressor includes: a recessed region recessed outward in a radial direction from a position forward of a front edge of each of the vanes to a position rearward of a rear edge of the vane; and a protruding region bulging inward in the radial direction at an intermediate position of the recessed region in a front-rear direction thereof. Thus, a distribution of static pressure in the radial direction on a surface of the vane is improved by a first recessed portion forward of the protruding region, and the static pressure on the tip side is raised by a second recessed portion rearward of the protruding region. | 12-13-2012 |

20150198952 | SENSOR CLEANING SYSTEM FOR AN AUTONOMOUS ROBOT DEVICE, BASE STATION AND CORRESPONDING METHOD - The inventive system comprises an autonomous robot device, a base station and a method operating the same. The autonomous robot device includes a sensor means, e.g. an optical sensor, and a propulsion means. The base station includes a cleaning means specifically adapted for cleaning the sensor means of the autonomous robot device. In a preferred embodiment the propulsion means of the autonomous robot device is configured to move the autonomous robot device in a manner suitable to generate a relative movement of the autonomous robot device with respect to the passive cleaning means arranged at the stationary base station to effect the cleaning of the sensor means of the autonomous robot device. | 07-16-2015 |

20100305925 | AUTONOMOUS EXPERIMENTAL DESIGN OPTIMIZATION - Iterative (nondeterministic) optimization of aerodynamic and hydrodynamic surface structures can be accomplished with a computer software program and a system using a combination of a variable encoding length optimization algorithm based on an evolution strategy and an experimental hardware set-up that allows to automatically change the surface properties of the applied material, starting with the overall shape and proceeding via more detailed modifications in local surface areas. The optimization of surface structures may be done with a computing device for calculating optimized parameters of at least one (virtual) surface structure, an experimental hardware set-up for measuring dynamic properties of a specific surface structure, and an interface for feeding calculated parameters from the computing device to the experimental set-up and for feeding measured results back to the computing device as quality values for the next cycle of the optimizing step. | 12-02-2010 |
