Pixel-based time–intensity curve analysis and apparent diffusion coefficient mapping of sinonasal organized hematomas [PDF]
, 2010 We present dynamic contrast-enhanced (DCE) and diffusion-weighted magnetic resonance imaging (MRI) features in three cases of sinonasal organized hematoma. The DCE MRI was evaluated by analyzing the time-intensity curve patterns on a pixel-by-pixel basis

Diffusion Tests for Chloride in Concrete Using Wind Tunnel Test
MATEC Web of Conferences, 2017 Diffusion coefficient of chloride in concrete is a predominant factor in chloride penetration into concrete. Two types of diffusion coefficient models are examined here: mean diffusion coefficient D, time-dependent diffusion coefficient D(t).

Time-dependent diffusion coefficient of proton in polymer electrolyte membrane [PDF]
, 2009 We investigated the time-dependent self-diffusion coefficients of water, D(T eff), in polymer electrolyte membranes at 278 K. TheD(T eff) was measured from T eff=0.7 to 100 ms by field gradient NMR techniques.
