The basic assumption in model engineering (MDE) is to consider models as first class entities. One of the most important kinds of models in MDE approaches are transformation models. Transformation models define operations between different models. However, there are many operations that are not efficiently handled by generic model transformations. For example, models transformations are not ada...

Run-time weaving of distributed aspects, if performed without any support for atomicity, endangers the global behavioral integrity of the application. Existing aspect-oriented middleware supports runtime weaving of distributed aspects, without addressing this problem. This inherently limits the type of behavioral changes that can be performed at run-time. This paper presents a model and an arch...

In this paper we briefly introduce an aspect language that can define cross-cutting effects on a set of UML 2.0 sequence diagrams. Our main contribution is to weave aspects and sequence diagrams at the model level. By basing the weaving upon a formal trace model for sequence diagrams, we ensure that the weaving is semantics-based. To avoid the intractability of working on complete trace sets, w...

The major developments in weaving machinery are highlighted. The maximum weft insertion rates achieved by the various shullleless weaving systems along with their application potential are described. Microprocessors have been recognized as an inseparable part of all modem weaving machines. The increased importance of versatility over productivity is highlighted keeping in view the present trend...

Article Submission For inclusion in Hyperseeing, authors are invited to email articles for the preceding categories to: Articles should be a maximum of eight pages. Plain weaving is one of the most beautiful and widely used geometric forms. In plain weaving, a set of distinct threads (or yarns) are interlaced with each other to form a fabric or cloth where each thread crosses the other threads ...

Executive Summary Traffic control in highway weaving sections is complicated since vehicles are crossing paths, changing lanes, or merging with through traffic as they enter or exit an expressway. There are two types of weaving sections: (a) single weaving sections which have one point of entry upstream and one point of exit downstream; and (b) multiple weaving sections which have more than one...

F the past 20 years weaving segments have been analyzed and designed using the methodologies and procedures provided in the 1965 Highway Capacity Manual (HCM).’ With the increase in urban growth in the mid-1960s, it was quickly realized that the procedures provided in the 1965 HCM for the analysis and design of weaving segments were in need of a critical review. In 1969 the National Cooperative...

Jointly deployed aspects may interact with each other. While some interactions might be intended, unintended interactions (interferences) can break a program. Detecting and resolving interferences is particularly hard if aspects are developed independently, without knowledge of each other. Work on interference detection has focused so far on the correctness of weaved programs. In this paper we ...

Dynamic weaving is much more flexible than static weaving because the separation of concerns remains at runtime. This results in highly configurable and adaptable applications, since the rules that govern the weaving of aspects can evolve during the application execution, according to different criteria – i.e. user preferences, execution context, etc. In this paper we describe the dynamic weavi...

A potentially important part of the design space for aspect-oriented languages remains largely unexplored: namely that space of languages that combine expressive pointcut languages and instance level aspect weaving. We define instance level aspect weaving as the ability to differentiate between two instances of a class and to weave them differently if needed. Note that instance level aspect wea...
