In reengineering legacy code it is frequently useful to introduce a design pattern in order to add clarity to the system and thus facilitate further program evolution. We show that this type of transformation can be automated in a pragmatic manner and propose a methodology for the development of design pattern transformations. We address the issues of the definition of a starting point for the ...

[GHJV94] proposed a number of design patterns that offer good solutions for recurring design situations. Along with the good solutions they also discuss naiv solutions to these design situations and argue why such naiv solutions should be replaced by a sound design pattern. Our position is that this exactly describes the task of OO reengineering: find patterns within a legacy OO program that sh...

Developing code free of defects is a major concern for the object-oriented software community. In this paper, we classify design defects as those within classes ( intra-class), those among classes ( interclasses), and those of semantic nature (behavioral). Then, we introduce guidelines to automate the detection and correction of inter-class design defects: We assume that design patterns embody ...

Design patterns describe good solutions to common and recurring problems. The applications of design patterns may vary in different layouts, which pose challenges for recovering and changing these design pattern instances since essential characteristics of each design pattern are described implicitly. In this paper, we categorize different characteristics of each design pattern as its traits in...

Network of public spaces composes of a network of interconnected land use and various elements of the city, such as synthetic and natural which shows the city as a whole. Network structure of public spaces is important because understanding this network as a structure presents us the formation of the city. This paper attempts to define the status of the network of public spaces in the city stru...

the request for natural gas attention to its adaption with environment and less pollution than the other fossil fuels has the highest growth in last decades. in result this energy has high geopolitical importance. iran with has about 2.18 percent of total world reserves, the largest in the world. but couldn't played important role in the natural gas geopolitics and even it hasn't in b...

The SWAN approach, presented in this paper, addresses the challenging task of developing Semantic Web Applications, i.e., Web applications that fully and effectively exploit and serve the Semantic Web as their operational environment. It is based on the support of two types of models, semantic domain models and conceptual user interface models, as well as on flexible model mappings. The SWAN fr...

We explain and provide examples of a formalism that supports the methodology of discovering how to adapt and personalize technology by combining randomized experiments with variables associated with user models. We characterize a formal relationship between the use of technology to conduct A/B experiments and use of technology for adaptive personalization. The MOOClet Formalism [11] captures th...
