Cognitive Dimensions is widely used framework to evaluate visual notations. Our research indicates that many programming environments let people program using multiple notations. Unfortunately, Cognitive Dimensions does not provide mechanisms to assess the relationship between the notations. In this paper we introduce our view of how notations are used in programming environments and we perform...

this paper presents characterizations of m-fuzzifying matroids bymeans of two kinds of fuzzy operators, called m-fuzzifying derived operatorsand m-fuzzifying difference derived operators.

we characterize compact composition operators on real banach spaces of complex-valued bounded lipschitz functions on metric spaces, not necessarily compact, with lipschitz involutions and determine their spectra.

The calculation of quark propagators for Ginsparg-Wilson-type Dirac operators is costly and thus limited to a few different sources. We present a new approach for determining spatially optimized operators for lattice spectroscopy of excited hadrons. Jacobi smeared quark sources with different widths are combined to construct hadron operators with different spatial wave functions. We study the R...
