Temperature is known to affect the fretting wear behaviour of metals; generally, a critical temperature is observed, above which there are substantial reductions in wear rate, with these being associated with the development of protective oxide beds in the fretting contact. This work has examined the gross-sliding fretting behaviour of a stainless steel as a function of bulk temperature and fretting...
A multitone frequency-biasing technique is applied to an integrated photoconductive (PC) sensor for application to free-space optical (FSO) communication systems. The introduced technique and integrated device provide the required optical transmission, detection, and retroreflection capabilities for both passive uplink and active downlink operations. The physical structure incorporates three triangular...
