In many problem domains, solutions take the form of unordered sets. We present the Set-Enumerations (SE)tree a vehicle for representing sets and/or enumerating them in a best-first fashion. We demonstrate its usefulness as the basis for a unifying search-based framework for domains where minimal (maximal) elements of a power set are targeted, where minimal (maximal) partial instantiations of a ...

We present a new algorithm, sie, for designing lumped parameter models from rst principles. Like the ibis system of Williams [1989, 1990], sie uses a qualitative representation of parameter interactions to guide its search and speed the test for working designs. But sie's interaction set representation is considerably simpler than ibis's space of potential and existing interactions. Furthermore...

This research uses a representative sample of U.S. nascent entrepreneurs to find that there is a positive relationship between their use of systematic search and their success in founding new firms. We control for mediating variables and find that searching systematically leverages firm founding by using an adaptive decision making style and social capital. Systematic search also appears to red...

BACKGROUND The use of electronic records in healthcare is increasing. To avoid errors, it is essential that the data displays used by these systems are usable: efficient, effective and satisfying. A wide variety of display techniques are used to present clinical data, but the best methods to assess the usability of these techniques have not been determined. This systematic review will answer th...

introduction: an article with a clear message can transfer research knowledge better. however, this is the case when the message suits the type of  study methodology (research design) and its results. the objective of  this study was to assess the presence of  message articles and the type of  study methodologies. methods: articles published between 2001 and 2006, on maternal care, diabetes, an...

PURPOSE We performed a systematic review to assess the functional outcomes of Birmingham Hip Resurfacing as reported in peer-reviewed literature. METHODS We performed a computerized search on the data sources up to February 2011. The following text and key words were searched: "Birmingham hip", "Birmingham hip resurfacing" and "Hip resurfacing". Each of these key words was again searched with...
