In this paper we give an introduction to the mathematical foundations of the optical waveguide design. A survey of the main results of the spectral theory of the Schr¨odinger operator on the line having compactly supported potential, with particular emphasis on the case of piece-wise constant potential is presented. This theory is then applied to the optical waveguide design problem of a piece-wis

This paper summarized the efforts performed to understand decay heat estimation from existing spent nuclear fuel (SNF), under the auspices of the Working Party on Nuclear Criticality Safety (WPNCS) of the OECD Nuclear Energy Agency. Needs for precise estimations are related to safety, cost, and optimization of SNF handling, storage, and repository. The physical origins of decay heat (a more correc
