We generalize two versions of Hardy's uncertainty principles due to Morgan and Cowling-Price in the real line R to harmonic NA groups. To do so, we use the Radon transforms and its relation with the Helgason-Fourier transformations on the class of the groups.
The One-factor-at-a-time (OFAT)plan was not recommended in practice in design of experiment, but following the recent study of OFAT, the effect and role of OFAT are better understood and realized, which has some advantages in optimization . Basing on our latest two papers, we first analyzed the prior knowledge, then studied optimization strategies of varying orders choices in OFAT experimentation based on prior knowledge. Some benefit and useful results for OFAT were gotten by simulation on many examples. Meanwhile, we did the comparison of OFAT based on prior knowledge with the orthogonal array under the equal number of experimental runs; the result is OFAT wins in average. Finally, we gave the conclusions and described the future work.
In this paper we present a class of non-linear unit analytic signals. By using real-variable methods, we also give the general characterization of such a kind of signals. Moreover, we prove that this class of fuctions is just a special case Mobius transform.
Visualization experimental investigation of pulsating heat pipes (PHP) was conducted. A PHP was charged with distilled water, TiO2/H2O nanofluid and CuO/H2O nanofluid as working fluids by a filling ratio of 55%, respectively. Both the nanofluids were made of distilled water and 1% volume fraction of nanoparticles. Experimental results showed that nanoparticles settled down in the motionless base liquid, but the oscillating motion in PHP would excite them to suspend them. The suspending stability of nanofluid got weak as temperature increased. Compared with the distilled water PHP, nanofluid PHP could work in lower heat loads, and had shorter startup time, lower thermal resistance, and temperature oscillation of smaller amplitude and higher frequency. At the working temperature of 110℃, the thermal resistance of PHP was 0.23℃/W, when it was filled with distilled water, and the thermal resistance would go down to 0.11℃/W or 0.13℃/W, when it was charged with TiO2/H2O or CuO/H2O. The two nanofluid PHPs had similar heat transfer performance.
