Error coding in asynchronous transfer mode, internet and satellites

The transmission of ATM, Internet, and satellite communications is unified through international standardized protocol embedment. Global and Local performance optimization are achieved through the combination of combinatorial, dynamic, and probabilistic programming. A simultaneous domino effect of bandwidth conservation, efficiency enhancement, reliability improvement, traffic congestion prevention, delay minimization, and speed multiplication are realized for any digital communication system, particular in Internet. With three levels of error coding in ATM cells, the loss cell recovery and bit integrity are preserved. From its mathematical roots, new combinatorial sets are systematically generated, and applications of the sets are identified. Among the applications, optimal sequences can be produced for multi-user and multi-function communication system designs. Optimality is in terms of maximum possible number of sequences with given sequence length and sequence characteristics. The results are unique and theoretically proven. By serial and parallel concatenation of error codecs, reliability of multimedia transmission can be satisfied to any desirable level. As a part of the unified transmission scheme, the acquisition and synchronization method of cascading sequences exhibits significant improvement in correlation properties and detection probabilities. A method of using block designs is demonstrated to derive, to generate, and to construct low-density parity check block codes and threshold decodable convolutional codes. An efficiency evaluation method is formulated for the combination operation of ATM, Internet, and satellites.

Workpiece attitude adjustment method based on measuring point and adaptive differential evolution algorithm

The invention discloses a workpiece attitude adjustment method based on a measuring point and adaptive differential evolution algorithm. The method includes the steps of initial matching and accuratematching. Firstly, reference points are selected on a theoretical workpiece curved surface and an actual curved surface to build corresponding local coordinate systems, and initial matching is realized by rough alignment of the local coordinate systems. In accurate matching, a target function based on a least-square distance is built through a point set after initial matching, an optimal solutionenables a value of the target function to be minimum and is searched by the adaptive differential evolution algorithm, so that an optimal accurate matching matrix is acquired. By the two steps, a final space transformation matrix can be acquired, adjustment amount corresponding to a machine tool can be calculated by combining a structure of the machine tool, the machine tool is adjusted, so that aworkpiece attitude is adjusted, a workpiece is accurately positioned, and allowances are uniformly distributed. According to the method, attitude adjustment and accurate positioning of testing partsmachined by an ISO (international standardization organization) five-axis numerical control machine tool are achieved, and effectiveness of the method is verified.
