Research into oil film coating of a steel pipe interior by oil mist blowing

Corrosion protection is one of the most frequently addressed issues in metallurgic and engineering applications. Oil film coating of inaccessible areas such as interior of a steel pipe is technically complicated. Because of that, the choice of the interior pipe film coating via oil mist is a viable solution. However, it is necessary to establish what will be the composition of the oil layer and what distance the required oil thickness will span. These are the aspects dealt with in the present paper

A criterion for the exponential stability of linear difference equations

AbstractWe give an affirmative answer to a question formulated by Aulbach and Van Minh by showing that the linear difference equation xn+1=Anxn,forn∈N in a Banach space B is exponentially stable if and only if for every f = {fn}n=1∞ ∈ lp(NB), where I < p < ∞, the solution of the Cauchy problem xn+1=Anxn+fn,forn∈N,x1=0 is bounded on N
