Collimator R&d Collimator R&d

The importance of collimator R&D with test beam facilities is demonstrated with the example of ILC collimator studies at SLAC End Station A. Related LHC collimator aspects and longer term plans are addressed. Presented at IDTB07, ILC Detector Test Beam workshop, Fermilab, USA, 2007.

Contributions of Prof . James R . Melcher to engineering education

This paper reviews the teaching and research career of the late Professor James R. Melcher. It describes his approach to the teaching of electric and magnetic fields bolstered by the lecture demonstrations he had developed. He is considered the founder of the modern day field of electrohydrodynamics. His undergraduate courses, reinforced by educational films which are briefly described, gave st...

(r, R+1)-factorizations of (d, D+1)-graphs

A (d, d + 1)-graph is a graph whose vertices all have degrees in the set {d, d + 1}. Such a graph is semiregular. An (r, r + 1)-factorization of a graph G is a decomposition of G into (r, r + 1)-factors. For d-regular simple graphs G we say for which x and r G must have an (r, r + 1)-factorization with exactly x (r, r + 1)-factors. We give similar results for (d, d + 1)-simple graphs and for (d...
