WebNov 25, 2005 · We present measurements of the near-field heat transfer between the tip of a thermal profiler and planar material surfaces under ultrahigh vacuum conditions. For tip-sample distances below 10(-8) m, our results differ markedly from the prediction of fluctuating electrodynamics. We argue that these d … Webevaluation of HMA construction thermal profiles. GPS enables precise location of anomalous locations in the HMA mat so that these locations’ long-term performance can be monitored. With GPS capabilities, the Pave-IR thermal profile is in an even better state of development to replace the manual thermal profiling required in Tex-244-F.
