A new technique for efficient encoding of LDPC codes based on the known concept of Approximate Lower Triangulation (ALT) is introduced. The greedy permutation algorithm is presented to transform ...

This note discusses sufficient conditions for a function of permutations (j1,⋯,jn) of the integers 1,2,⋯,n to have a minimum at the permutation (j1 *,⋯,jn *) and derives a solution algorithm that is ...

The Rio table seems pretty conventional at first glance. Designed by the architecture firm Studio Integrate for the British furniture brand Morgan, it has a glass top and tapered wood legs. But look ...
