Some new models are being developed to aid in studying PMS.

Introductory Remarks

We first review B-splines and splines constructed using B-splines as the basis functions.

Introductory Remarks

H+3 was discovered by J. J. Thomson (1911), who spent most of his research life on studies of the discharges of electricity through gases. He studied negative (cathode) rays and discovered the electron in 1897; he then studied positive (canal) rays, extending Wien’s work, and identi­ ed the proton. When Aston became his assistant in 1910, an early prototype of a mass spectrometer resulted and H...
