We have reviewed humidity sensors based on various materials for both relative and absolute humidity, including ceramic, semiconducting, and polymer materials. In the majority of publications, there are few papers dealing with absolute humidity sensors, which have extensive applications in industry. We reviewed extensively absolute humidity sensors in this(More)
Mixed chimerism has been shown to lead to prolonged major histocompatibility complex (MHC) disparate allograft survival and immune-specific tolerance; however, traditional conditioning regimes often involve myeloablation, which may pose a significant safety risk. In this study we examined the use of donor C57BL/6 (H-2(b)) immature dendritic cells (imDCs) to(More)
Two ultra-thin TiO(2) films with platinum electrodes were prepared on a porous anodic aluminium oxide thick layer and a ceramic plate, respectively. It was found that in both TiO(2) films the conductance was almost proportional to the fourth root of the H(2) concentration in N(2) ambient at 500 °C. A quantitative model based on the spill-over mechanism is(More)
The increase of array size and decrease of cell size make the testing of infrared focal plane array (FPA) being difficult. A design for test scheme, cross-check test, for infrared focal plane array (FPA) is presented in this paper. For an array size of M by N, the testing times can be reduced from the order of M*N to M+N. Analysis on the fault detectability(More)
