Ion Mobility-Mass Spectrometry: Time-Dispersive

2014-12-19 · Highlights of the historical development of the field are presented in Figure 1, right.Ion mobility and mass spectrometry trace their foundations to the X-ray experiments of Thomson and Rutherford in the late 1800s, with Tyndall making significant improvements in the analytical capabilities of ion mobility around the 1930s. During this early era of discovery, a variety of ion mobility

Convergence Properties of the Nelder--Mead Simplex …

2018-9-18 · The Nelder--Mead simplex algorithm, first published in 1965, is an enormously popular direct search method for multidimensional unconstrained minimization. Despite its widespread use, essentially no theoretical results have been proved explicitly for the Nelder--Mead algorithm. This paper presents convergence properties of the Nelder--Mead algorithm applied to strictly convex functions in
