In light of the growth in vertically specialized in global trade, the present paper uses input– output tables from the World Input–Output Database to construct an environmental multi-regional input–output model to calculate the CO₂ emissions embodied in China's international trade during...

Titterington proposed a recursive parameter estimation algorithm for finite mixture models. However, due to the well known problem of singularities and multiple maximum, minimum and saddle points that are possible on the likelihood surfaces, convergence analysis has seldom been made in the past...

This paper presents a method for stability analysis of N-cell cascade step-down buck converters, which is a kind of complex nonlinear system. A nonlinear model in the form of time-variant state equations is derived, and then the loop gain describing the overall system is introduced. With the...
