Implementing NGS Draft Guidelines for GPS-Derived Orthometric Heights
The need to determine accurate heights relative to the North American Vertical Datum of 1988 (NAVD 88) is more prevalent today than ever before. Projects are no longer isolated unto themselves, or designed in a box. Due to global and regional issues such as the environment, and municipal planning, the need to represent the topographic features of the earth accurately in three dimensions is of p...
متن کاملExpected Heights in Heaps
In this paper several recurrences and formulas are presented leading to an upper bound and a lower bound, both logarithmic, for the expected height of a node in a heap. These bounds are of interest for algorithms that select the kth smallest element in a heap. CR categories: E.1, F.2.2, G.2.1.
متن کاملHsp90 reaches new heights
Introduction Hsp90 (heat-shock protein 90) is an abundant molecular chaperone, but its function seems to be restricted to the folding of proteins involved in cell signalling, such as transcription factors and protein kinases. This restricted set of ‘clients’ (see Fig. 1) makes Hsp90 an attractive target for cancer therapeutics. As an anti-Hsp90 drug is now in clinical trials, the meeting was re...
متن کاملHeights and Weights
Tables of the relation between height and weight are now common in many countries, and if reasonably used are certainly helpful. It is not that a youth, a man, or woman, of a certain height must closely conform to the weight tabulated, a margin of 15 or 20 per cent, on either side is allowable. Such a table is undoubtedly useful in comparing the recruits or the prisoners it may be of one year (...
متن کاملIntroduction to Heights
Notes for a talk in Stanford’s Arithmetic Dynamics Seminar, Apr. 29, 2014. This talk is an introduction to the theory of heights on projective varieties over local and global fields. I will also say something about canonical heights for a dynamical system, and a local-global formula for these. This material is from Chapters 1-2 of the book by Bombieri and Gubler on heights [BG]; also Silverman’...
