A method for testing a magnetic head to determine whether the magnetic head is unacceptably affected by temperature variations. The coated article comprises a substrate having a surface and a coating covering a portion of the surface and comprising a polymeric material and a temperature regulating material dispersed in the polymeric material. When executing image processing, parallel processing is performed for the second-type process segment relating to the i-th partial image and the first-type process segment relating to any of the -th to the -th partial images. The present invention is directed to the use of GCIB surface modification to overcome prior problems of thrombosis and restenosis. The invention further relates to the use of such a catalyst, for example but not limited to, in a process for the conversion of paraffins, olefins and aromatics in a mixed feedstock into the product having high amount of branched paraffins with decreased aromatics and olefins, a useful gasoline blend, with negligible production of lighter gases. The electric powertrain further includes at least one electric motor operably coupled to the generator, a plurality of driving members, and at least one power electronics unit configured to control at least one of the engine and the generator.
