This paper proposes a hybrid approach for the fault detection of rolling element bearing which combine Singular value decomposition (SVD) with LMD algorithm and the results show the excellent performance of the proposed technique in revealing the rolling element bearing fault.
If the discolouration is more localised, in spots or streaks, the problem may still lie in contamination of the raw material and regrind but localised decomposition can result from some material being held up in dead spots in the cylinder and mould feed system.
BD or primal decomposition methods exploit only the primal structure of the original problem.
One of the factors that determine the evolution of detonation processes in energy condensed systems based on ammonium saltpeter is the rate of exothermic decomposition in the system which, in its turn, is caused by the parameters of ammonium nitrate thermal decomposition.
A decomposition of a multigraph G is a partition of its edge set into edge disjoint subgraphs [H.
The Adomian decomposition method (ADM) is a creative and effective method for exact solution of functional equations of various kinds.
The pyrolysis process of kerogen is more complex since the thermal decomposition ranges of several host minerals, such as dawsonite, interfere with the decomposition process of kerogen.
In addition, there have been a few reports of drinking water contamination with enteric pathogens following the burial of animal carcasses, and some infectious materials such as anthrax spores or prions can remain within the soil after carcass decomposition [3,4].
One of the strategies for assessing the consequences of partial or total removal of the accrued sugar cane straw and management practices is through a better understanding of the decomposition dynamics of straw under field conditions.
