Trust and reputation mechanisms are often used in peer-to-peer networks, multi-agent systems and online communities for trust-based interactions among the users. Trust values are used to differentiate among members of the community as well as to recommend a service provider. Although different users have different needs and expectations in different aspects(More)
(a) (b) Fig. 1. Red-blue (Republican-Democrat) map of the USA showing 2004 election results from the New York Times [3]: (a) geographically accurate map, (b) a population cartogram. Abstract— Cartograms are maps in which areas of geographic regions (countries, states) appear in proportion to some variable of interest (population, income). Cartograms are(More)
Trust and reputation mechanisms are often used in peer-to-peer networks, multi-agent systems and online communities to differentiate among members of the community as well as to recommend service providers. Although different users have different needs and expectations in different aspects of the service providers, few exiting trust-models use(More)
A convex polyhedron P is k-equiprojective if all of its orthogonal projections, i.e., shadows, except those parallel to the faces of P are k-gon for some fixed value of k. Since 1968 it is an open problem to construct all equiprojective polyhedra. Recently, Hasan and Lubiw [8] have given a characterization of equiprojective polyhedra. Based on their(More)
Coherent light scattering presents complex spatial patterns that depend on morphological and molecular features of biological cells. We present a numerical approach to establish realistic optical cell models for generating virtual cells and accurate simulation of diffraction images that are comparable to measured data of prostate cells. With a contourlet(More)
BACKGROUND Recent reports provide a conflicting picture with a stable prevalence of gastroparesis (GP) in a population-based study, but a more than doubling in hospitalizations for gastroparesis within the last 10 years. We hypothesized that this apparent discrepancy is due to changes in disease recognition and coding rather than prevalence. METHODS Using(More)
