Kogelnik's coupled-wave theory has provided a well-established basis for understanding how light propagates inside a volume hologram, giving an accurate approximation of the diffraction efficiency in this type of hologram. In this paper we elaborate on some aspects of the…

This thesis defines Defeasible Logic Programming and provides a concrete specification of this new language through its operational semantics. Defeasible Logic Programming, or DeLP for short, has been defined based on the Logic Programming paradigm and considering features of recent…

Holographic data storage is a new optical technology, which allows an important number of bits to be stored in a recording material. In this paper, holographic data pages were stored in a polyvinyl alcohol/acrylamide (AA) photopolymer layer, using a peristrophic…

Cette étude porte sur la dimension intersubjective de la souffrance qui affecte le rapport du souffrant à son corps, au temps et à l’espace vécus de même que son identité narrative et sa mémoire narrative. Mon argument principal est que…

Bleached holograms are one of the most interesting techniques used to produce phase holograms of high quality on photographic emulsions. Of particular interest is the method of fixation-free rehalogenating bleaching. In this paper we will study the influence of the…

Bleaching is one of the most widely used techniques in the production of phase holograms of high quality on photographic emulsion, particularly in rehalogenating techniques without a fixation step. These techniques were very well understood when Agfa 8E75 HD emulsion…

Genetic testing technologies are rapidly moving from the research laboratory to the market place. Very little scholarship considers the implications of private genetic testing for a public health care system such as Canada’s. It is critical to consider how and…

As a way of forecasting future evolution of inequalities in disease burden and mortality, trends in preventive health behaviours by social class were examined. Using the Spanish National Hearth Survey from 1987 to 1997 the evolution of the Health Practices…

As Personality Disorder continues to be a subject of intense public and professional debate, this study has explored by means of an in-depth interview the views of fifty people to whom this diagnosis has been attributed, to include: demographic data,…
