This paper proposes a long-stroke linear switched reluctance machine (LSRM) with a primary and a secondary translator for industrial conveyance applications. The secondary one can translate according to the primary one so that linear compound motions can be achieved. Considering the fact that either one translator imposes a time-variant, nonlinear disturbance onto the other, the selftuning position controllers are implemented for the proposed linear compound machine and experimental results demonstrate that the absolute steady-state error values can fall into 0.03 mm and 0.05 mm for the secondary and primary translator, respectively. A composite absolute precision of less than 0.6 mm can be achieved under the proposed control strategy [ABSTRACT FROM AUTHOR]

Let G be a multigraph, g and f be integer-valued functions defined on V( G). Then a graph G is called a ( g, f)-graph if g( x)≤ degG( x)≤ f( x) for each x∈ V( G), and a ( g, f)-factor is a spanning ( g, f)-subgraph. If the edges of graph G can be decomposed into ( g, f)-factors, then we say that G is ( g, f)-factorable. In this paper, we obtained some sufficient conditions for a graph to be ( g, f)-factorable. One of them is the following: Let m be a positive integer, l be an integer with l= m (mod 4) and 0≤ l≤3. If G is an -graph, then G is ( g, f)-factorable. Our results imply several previous ( g, f)-factorization results. [ABSTRACT FROM AUTHOR]
