TRANSITION CURVES FOR RAILWAYS. (INCLUDING APPENDIX).

Multi-conductor transmission line model for electrified railways: A method for including responses of lumped devices

For studying the response to transients caused by lightning and other electromagnetic disturbance sources, electrified railway systems can be represented as a system of multiconductor transmission lines (MTL) above a finitely conducting ground. The conductors present in this system would be wires for traction power supply, auxiliary power, return conductors for traction current, the tracks, and...

Appendix and erratum: ‘Massey products for elliptic curves

The paper [6] contains a few errors in the basic assumptions as well as in the formula of corollary 0.2. First of all, it should have been made clear at the outset that the regular model E for the elliptic curve E must be the minimal regular model, and X the complement of the origin in the regular minimal model. Similarly, the tangential base-point b must be integral, in that it is a Z−basis of...

Including Non-markovian Transition Probabilities

New radiative transition probabilities for Fe IV including fine structure

We present new calculations for transition probabilities of Fe IV, with much more extensive datasets than heretofore available. The large-scale close coupling R-matrix calculations yield 1,798 LS bound states with n ≤ 11 and l ≤ 9, and corresponding transition probabilities for 138,121 dipole allowed transitions in the form of oscillator strengths f , line strengths S , and A-coeffficients for ...
