Ra, Pb transformations were successfully applied to establish invertibility theory for linear and quasi-linear finite automata over finite fields. In a previous
In a district heating and cooling system, i.e. Beijing combined heating cooling and power (CHCP) system studied here, high temperature water generated by two co
Petroleum science has made remarkable progress in organic geochemistry and in the research into the theories of petroleum origin,its transport and accumulation.
In this topic,a new approach to the analysis of time-variation dynamics is proposed by use ofLegendre series expansion and Legendre integral operator matrix.Th
A three-dimensional nonlinear numerical model with inclined pressure was developed to compute the saltwater intrusion at the Yangtze River Estuary. The σ-trans
