Combined manipulation of blur, line length and contrast reveal two distinct processes involved in curvature detection. When line length is small relative to blur, thresholds are almost directly proportional to blur and independent of line length. When line length is large relative to blur thresholds are directly proportional to line length and independent of blur. The aspect ratio (line length/...

We report on magnetoconductance measurements of metallic networks of various sizes ranging from 10 to 10(6) plaquettes, with an anisotropic aspect ratio. Both Altshuler-Aronov-Spivak h/2e periodic oscillations and Aharonov-Bohm h/e periodic oscillations are observed for all networks. For large samples, the amplitude of both oscillations results from the incoherent superposition of contributions...

We propose a primitive model of Janus ellipsoids that represents particles with an ellipsoidal core and two semisurfaces coded with dissimilar properties, for example, hydrophobicity and hydrophilicity, respectively. We investigate the effects of the aspect ratio on the self-assembly morphology and aggregation processes using Monte Carlo simulations. We also discuss certain differences between ...

The determination of the nematic order parameter S and the orientational distribution function (ODF) from scattering data involve severe approximations. The validity of these are studied here using Monte-Carlo simulations of hard spherocylinders with an aspect ratio of 15 for varying densities in the isotropic and nematic phase. The "exact" ODF of the rods, the "exact" value of S, and the inten...

We describe the Aspect Markup Language (AML), an XML-based AOP language for programming aspects. AML separates the binding instructions, written in XML, from the executable aspect code, written in a regular programming language. This separation by itself has some advantages, namely for testing. But the main goal of AML is to provide a highly extensible AOP platform, with which programmers can e...

Aspect oriented programming is a way of reducing the complexity of software development, in the sense that it is easier to reason about isolated concepts. The complexity of web applications has been increasing in the last few years, mainly, because customers are requesting more and more. We think that advanced separation of concerns can be a good strategy to reduce the complexity of web applica...

When aspect-oriented modeling techniques are used in the context of Model-Driven Engineering, a possible way of obtaining an executable from an aspect-oriented model is to map it to code written in an aspect-oriented programming language. This paper presents important challenges that a modeler has to face when mapping aspect-oriented models to an aspect-oriented programming language: mapping st...

This paper describes our system for generating Chinese aspect expressions. In the system, the semantics of different aspects is characterized by specific temporal and conceptual features. The semantic applicability conditions of each individual aspect are theoretically represented by an aspect selection function (ASF). The generation is realized by evaluating implemented inquiries which formall...
