The combination of aspect-oriented programming and framework technology boosts software reuse and brings separation of concerns to a new, more generic level. On the one hand, AOP enables the separate implementation of crosscutting concerns. Frameworks, on the other hand, allow us to reuse and customize a particular implementation in different applications. By means of a security example, we sho...

Xuan Zhang Advisor: Prof. Kim R. Dunbar Apr. 16, 2012 Room 2102 Ever since its appearance about 17 years ago, 1 the term Metal-Organic Frameworks (MOFs) has been gaining tremendous attention in chemistry and crystal engineering because of the fascinating solid state materials it pertains to. These MOFs, also known as porous coordination polymers (PCPs) are characterized by their high porosity, ...

A direction-length framework is a pair (G, p), where G = (V ;D,L) is a ‘mixed’ graph whose edges are labeled as ‘direction’ or ‘length’ edges, and p is a map from V to R for some d. The label of an edge uv represents a direction or length constraint between p(u) and p(v). Let G be obtained from G by adding, for each length edge e of G, a direction edge with the same end vertices as e. We show t...

Abstract argumentation frameworks (AFs) are one of the most studied formalisms in AI. In this work, we introduce a certain subclass of AFs which we call compact. Given an extension-based semantics, the corresponding compact AFs are characterized by the feature that each argument of the AF occurs in at least one extension. This not only guarantees a certain notion of fairness; compact AFs are th...

According to Koffka (1935), the lightness of a target surface is determined by the relationship between the target and the illumination frame of reference to which it belongs. However, each scene contains numerous illumination frames, and judging each one separately would lead to an enormous amount of computing. Grouping those frames that are in the same illumination would simplify the computat...

We formulate a concise deformation theory for periodic bar-and-joint frameworks in Rd and illustrate our algebraic–geometric approach on frameworks related to various crystalline structures. Particular attention is given to periodic frameworks modelled on silica, zeolites and perovskites. For frameworks akin to tectosilicates, which are made of one-skeleta of d-dimensional simplices, with each ...

In this paper we combine fuzzy set theory and argumentation to facilitate the use of fuzzy arguments and attacks. Unlike many existing approaches, our work does not require the use of any parameters, bringing it closer to Dung’s work in spirit. We begin by introducing Fuzzy Argumentation Frameworks, and specialise them using the Gödel t-norm. We then examine this framework’s properties and show...

Developers of QoS (Quality of Service) applications need component frameworks that support QoS to improve their development process. We propose to use the component infrastructure level for the integration of QoS facilities to avoid the problems of QoS infrastructures dependencies, and to simplify the development process of applications. This paper introduces our model of QoSaware component, an...
