A comparative survey of synchronization algorithms for continuous media in network environments

Abstract: This paper makes a survey of algorithms proposed for continuous media synchronization in network environments. We classify media synchronization control techniques used in the algorithms into four categories: basic control, preventive control, reactive control and common control. We also pick four representatives from among the media synchronization algorithms and give outlines of them in order to explain how the techniques are employed in each algorithm. Furthermore, we make a comparison among 38 algorithms in terms of factors such as clocks, advance information on network delay bounds and synchronization control techniques, which determine the design of each algorithm.

Nonlinear Finite-Element Analysis for Hysteretic Behavior of Thin-Walled Circular Steel Columns with In-Filled Concrete

Abstract: The strength and ductility of thin-walled steel columns under cyclic loads are considerably upgraded by filling concrete into hollow spaces surrounded by steel tube and diaphragms. The above thin-walled steel columns filled with concrete are referred here to as thin-walled CFT columns. Up to the present, no sufficient and precise research has been conducted on the versatile finite-element model (FE model) analysis that can take into account the upgrading mechanism of thin-walled CFT columns in a direct manner. Herein, an accurate FE model is investigated in order to fully include the important factors such as cyclic local buckling of steel tube, nonlinear behavior of confined concrete, and interface action between steel tube and in-filled concrete. The validity of the proposed models is examined by comparing with the results of cyclic loading experiments on CFT columns. With the proposed model, the effect of in-filled concrete on the upgrading mechanism of thin-walled CFT columns is discussed in detail.

Gradient descent bit flipping algorithms for decoding LDPC codes

Abstract: A novel class of bit-flipping (BF) algorithms for decoding low-density parity-check (LDPC) codes is presented. The proposed algorithms, which are called gradient descent bit flipping (GDBF) algorithms, can be regarded as simplified gradient descent algorithms. Based on gradient descent formulation, the proposed algorithms are naturally derived from a simple nonlinear objective function.
