Abstract: An intelligent layout design method of curvilinearly stiffened structure based on image feature learning. Firstly, the design variables of the curvilinearly stiffened structure are determined based on the path function. The autoencoder network is built to complete the learning of the structural characteristics of the image, and the transfer learning of the model is further carried out. The convolution neural network is built to complete the learning of the image set with mechanical response labels. Finally, the evolutionary algorithm is used to optimize the layout of the curvilinearly stiffened structure based on the model. The invention solves the problem that the traditional optimization method is difficult to deal with the optimization design with many and variable design variables, and is expected to become one of the most potential technical means involved in the layout design of components in the engineering field.

Abstract: In various embodiments, methods and systems for cross-filtering based on configurable direct relationships are provided. A selection of a first endpoint of a first table and a second endpoint of a second table is received. A direct relationship object is configured between the first table and the second table based on the first endpoint and the second endpoint. A cross-filtering direction and endpoint cardinality settings can also be configured for the direct relationship object. The direct relationship object may be configured as a many-to-one, one-to-many, or one-to-one. Automatic cross-filtering is configurable and can be set to cross-filter in one direction, the reverse direction, or both directions, with bidirectional cross filtering being a default configuration. The direct relationship object between the first endpoint and the second is configurable, such that, cross-filtering the first table and the second table to select rows for cross-filtering results is based on the cross-filtering direction.

Abstract: The process of acquiring SSL certificates for enterprise SSL customers is improved by reducing the number of steps used to acquire the SSL certificate and streamlining the process. An on-line CSR generator on the certificate enrollment form is used to submit the customer information (i.e. Common Name, Organizational Unit, Organization, City/Locality, State/Province, and Country Code) and generate the CSR. By making the CSR generation part of the enrollment process, the administrator can use the same enrollment form to submit the customer information along with the contact information pertinent to the enterprise.

Abstract: An MPEG-2 digital TV headend and settop box includes a method and apparatus for enabling the presentation of electronic program guide (EPG) information. Television program guide information is downloaded from a source of television programming data to the headend of the TV broadcast system. The downloaded EPG data is translated into a plurality of HTML Web pages, which are continuously transmitted as a rotating data carousel in an MPEG-2 data stream. The digital TV settop box further includes a general-purpose web browser responsive to viewer commands to select and display a selected web page from the rotating carousel of HTML web pages. The digital TV settop further includes a data cache for downloading and storing partial HTML web page EPG information in advance, which reduces the necessary bandwidth allocated for the EPG information, and allows the settop box to quickly display the basic information for a channel related program guide.
