We p m t a novel method for obtaining Floquet or time-dependent wavefunctions for atoms in laser fields. This method has the potential to be more stable and/or faster than previous, methods. The main idea is IO include the effects of the laser field in a gauge that smoothly changes character as a function of distance. This transformation allows us to formally account for the analytic behaviour ...

Healthcare providers play a major role in attending to all domains of health in a population. In terms of modem healthcare delivery, better health outcomes for population can be achieved by engaging multi-disciplinary expertise. In the last decade, pharmacy profession had transformed tremendously in terms of health and pharmaceutical service provision to both patients and general population. Wi...

“Qualitative GIS – isn’t that kind of an oxymoron?” This comment from a colleague with years of experience working with GIS echoes the title of an editorial from an edition of Environment and Planning dedicated to the topic (Kwan and Knigge: 2006), and voices lingering concerns about the limitations of GIS. Qualitative GIS: A Mixed Methods Approach serves as an invitation to scholars in fields ...

A block image labeling method is presented. It does not assume that the blocks to be treated are already segmented nor that they contain homogeneous data. It is based on connected component analysis to label the blocks' contents as small letter text, medium letter text, large letter text, graphics or photographs, giving the percentage of each of these components with respect to the surface area...

This paper presents a mixed approach to spoken language understanding that tries to make best use of the advantages of both statistical and knowledge-based algorithms. Results obtained on ATIS (Air Travel Information System) scenario transferred to Italian language are presented and discussed.

The feature interaction problem is prominent in telephone service development. Through a number of case studies, we have discovered that no one semantic framework is suitable for the synthesis and analysis of formal feature requirements models. We illustrate our mixed-model approach, where we use OO LOTOS, B and TLA+ in a complementary fashion. A simple combination of call forwarding and call s...

In the paper, a new evolutionary algorithm (EA) for mixed tree learning is proposed. In non-terminal nodes of a mixed decision tree different types of tests can be placed, ranging from a typical univariate inequality test up to a multivariate test based on a splitting hyperplane. In contrast to classical top-down methods, our system searches for an optimal tree in a global manner, i.e. it learn...

In this paper, we consider the problem of finding a mixed upward planarization of a mixed graph, i.e., a graph with directed and undirected edges. The problem is a generalization of the planarization problem for undirected graphs and is motivated by several applications in graph drawing. We present a heuristic approach for this problem which provides good quality and reasonable running time in ...

In this article, we propose a new metaphorical framework for understanding and using mixed methods evaluation. Our re-conceptualization of mixing methods provides important insights into the theoretical and practical challenges of using a mixed method approach. Mixed methods can create philosophical and practical dilemmas in the ways data are collected, analyzed, interpreted and reported. We us...
