A method of wear detection of a coated belt or rope includes measuring an initial electrical resistance of one or more cords, strands or wires of the coated belt or rope. Further, the invention refers to method for mounting power-dissipating components onto a circuit board, comprising the steps of determining the thermal behavior of said power-dissipating components; and determining, in accordance thereto, the placement of said power-dissipating components on both a top side and a bottom side of said circuit board. The matrix H is defined by distortion angles \u201cb\u201d towards a plane direction and a distortion angle \u201ca\u201d towards a depth direction of the source image, and the matrix HF is defined according to a camera parameter matrix K. In the TV system, the size of the central portion is fixed while the size of the sidepanel portion can be adjusted depending on the displaying mode. Interceptor guidance uses the initialization and the propagated states and typing information to command the interceptor.
