    What we have in Figure 10.1 are two frequency distributions of yards per play. A frequency distribution shows the number of times each score (in this case, the number of yards) is obtained. We can tell at a glance that these two distributions are markedly different. A pass play is a study in contrasts; it leads to extremely variable outcomes.

    Dec 01, 2019· Abstract. In this paper, an enhanced performance of dual core D-shape photonic crystal fiber utilizing surface plasmon resonance (DD-PCF-SPR) based sensor is numerically proposed and analyzed. The thickness of gold and pitch parameter are optimized to 30 nm and 1.9 um, respectively, which ensures superior sensor performance.

  • Mineral Deposit Value - How to Calculate the Potential

    As you can see in the example above, the deposit does not have to be enormous in size (only 500 meters long by 100 meters wide) to contain a valuable deposit (approximately $6 billion worth of minerals). However, in order to be as realistic as possible about this valuation, you can not assume that the complete ore body contains the same grade (i.e. 2% copper and 1.5 gram per tonne gold).
