Abstract: A secure data routing method and system are disclosed. Logical communication channels are established that each associate an IP address and a protocol port associated with a first computer system to an IP address and a protocol port associated with a second or third computer system. Some logical communication channels associated with the second computer system and some logical communication channels associated with the third computer system are associated with the same IP address and protocol port associated with the first computer system. Data packets are received and parsed to find tokens embedded in the headers. A first data packet embedding a first token is associated to a first source and is decrypted using a first decryption key associated with the first source. A second data packet embedding a second token is associated to a second source and is decrypted using a second decryption key associated with the second source.

Abstract: Various embodiments of the present technology provide a novel deep learning-based error correction coding scheme for AWGN channels under the constraint of moderate to low bit quantization (e.g., one-bit quantization) in the receiver. Some embodiments of the error correction code minimize the probability of bit error can be obtained by perfectly training a special autoencoder, in which “perfectly” refers to finding the global minima of its cost function. However, perfect training is not possible in most cases. To approach the performance of a perfectly trained autoencoder with a suboptimum training, some embodiments utilize turbo codes as an implicit regularization, i.e., using a concatenation of a turbo code and an autoencoder.

Abstract: An apparatus is provided for finite element modeling and analysis of a structural product. A pre-processing system may produce a finite element model of a structural product including component parts joined by a fastener. The finite element model may represent the product by respective meshes of elements including shell or solid elements for the component parts, and beam and spring elements for the fastener in which at least one spring element has an axial offset from the shell or solid elements with respect to an axis of the fastener. A processing system may perform a finite element method (FEM) failure analysis of the finite element model under an external load that is transferable from the component parts to the fastener. The FEM failure analysis may produce an output that indicates a behavior of the fastener, and the FEM failure analysis may predict a component failure rate of the fastener based on the behavior.
