In this paper all cocyclic Hadamard matrices of order less than 40 are classified. That is, all such Hadamard matrices are explicitly constructed, up to Hadamard equivalence. Thi...
In order to solve the low efficiency problem of directly querying single node probability in the set of all ordinary XML data obtained by enumerating possible world set of the cor...
We describe a general construction principle for a class of self-similar graphs. For various enumeration problems, we show that this construction leads to polynomial systems of rec...
High performance designs often use the on-chip device PLLs for accurate test clock generation during testing. The on-chip clock generator is designed in a programmable way to faci...
In this paper we study four algorithms for computing the frequency of a given partial order. Here the frequency of a partial order is the number of standard labellings respecting t...
