In one embodiment, a method includes determining by a computer system a distance between a first value associated with a first image and a first cluster center associated with at least one image and determining by the computer system the first image and the at least one image are not similar when the determined distance is more than a threshold distance. The binuclear organometallic complex, which can be suitably used to form an organic layer of an organic electroluminescent device, produces luminescence in the wavelength range of 430-650 nm, and induces white electroluminescence when combined with green and red luminescent materials. This therefore materializes, between the inlet and each outlet of the structure, at least one continuous passage to direct a fluid circulating inside it. The body-worn monitoring station comprises monitoring equipment. An indicator displays the angular offset between the wheel support member and the arm, which is indicative of the angular offset between the vehicle body axis and the vehicle drive axis.
