Superheavy elements—chemical elements which are much heavier than those which we know of from our daily life—are a persistent dream in human minds and the kernel of science fiction literature for about a century. This book describes in Chap. 1 how today this dream becomes true at a few accelerator laboratories, what the tools are to synthesize these elusive, man-made elements in heavy-ion nuclear reactions and how to detect the specific nuclear decays which terminate their existence shortly after they are created. The current status of experimental and theoretical insights into this very unique region of nuclear stability is briefly reviewed. The last chapter outlines historical developments, from first scientifically sound ideas about the existence of superheavy elements, which surfaced during the mid-50s, all the way to the beginning of the current research programs described in Chap. 1. It also discusses experimental attempts and prospects of the search for superheavy elements in Nature. 

This Chapter briefly reviews the historical development of safety and reliability assessments within the maritime industry and outlines the application of such assessments. This is followed by a review of the current status of safety and reliability assessments in the United Kingdom. The different databases available in the maritime industry are described, highlighting the information that each of these databases carries. The contents in the book are finally outlined. 

The X chart considers only the current data value in assessing the status of the process. Run rules have been developed to include historical information such as trends in data. The run rules sensitize the chart, but they also increase the false alarm probability. The warning limits are useful in developing additional run rules in order to increase the sensitivity of Shewhart charts. The warning limits are established at 2-sigma level, which corresponds to o /2=0.02275. Hence,...
