Aspect-Oriented Programming (AOP) has been considered a promising abstraction principle to reduce the problem of code tangling and make software structure clean and configurable. This paper addresses the aspect support in the design level while it has been focused mainly in the implementation/coding phase. We propose an extension to Unified Modeling Language (UML) to support aspects properly wi...

The European Community plays an active role in giving concrete expression to the new developments taking place in modelling languages and in UML (Unified Modelling Language) [1] in particular. These developments often make use of norms and specifications that are mainly carried out by the OMG (Object Management Group). The main objective of the European NEPTUNE project led by CS (Nice Environme...

Solid modeling has been recognized as a powerful computer -aided design tool, being informationally complete and semantically well-formed. However, it is insufficient by itself to support the design process of complex artifacts such as buildings , since it lacks the abstraction properties provided by computer-aided drafting tools. This paper presents an integrated approach to geometric modeling...

The Unified Modeling Language (UML) still lacks a formal and commonly agreed specification of its semantics that also accounts for UML’s built-in semantic variation points and extension mechanisms. The semantics specification of such extensions must be formally integrated and consistent with the standard UML semantics without changing the latter. Feasible semantics approaches must thus allow ad...

Software design is a cognitively challenging task. Most software design tools provide support for editing, viewing, storing, and transforming designs, but lack support for the essential and difficult cognitive tasks facing designers. These cognitive tasks include decision-making, decision ordering, and task-specific design understanding. This paper describes Argo/UML, an object-oriented design ...

It is a powerful modeling language used to represent the research problems visually. Many research has been done on modelling problems by the use of UML, but limited research papers are reported in literature on applications of UML for the computer architecture research problems. By the use of UML, software and hardware architecture problems can be solved and performance can be judged after mod...

The success of an e-learning system is highly dependent on the quality of its educational content and how effective, complete, and simple the design tool can be for teachers. Educational modeling languages (EMLs) are proposed as design languages intended to teachers for modeling diverse teaching-learning experiences, independently of the pedagogical approach and in different contexts. However, ...

this work presents an experimental investigation of the influence of the six important machining parameters (tool nose radius, tool rake angle, feed rate, cutting speed, cutting environment (dry, wet and cooled) and depth of cut) on surface roughness & material removal rate in the machining unidirectional glass fiber reinforced plastics (ud-gfrp) composite using carbide (k10) cutting tool durin...

In this work, improved heat generation models are developed for straight and tapered shoulder geometries with different tool pin profiles in friction stir welding. The models are developed considering the welding process as a combination of the pure sliding and the pure sticking conditions. From the results, the amount of heat generation is directly proportional to the number of edges in the pi...
