The majority of studies that analyze clone evolution is limited to open-source software. Although providing important insights, it is unsure whether findings can be transferred to industrial contexts. We conducted a study on clone evolution in industrial systems to complement the findings of our previous study on clone evolution, which was limited to open-source systems. In this paper, we prese...

Code cloning is a severe problem that negatively affects industrial software and threatens intellectual property. This paper presents a novel approach to detecting cloned software by using a bijection matching technique. The proposed approach focuses on increasing the range of similarity measures and thus enhancing the recall and precision of the detection. This is achieved by extending a well-...

During the maintenance of a program, not only the source code but also the code clones contained in it evolve. Some recent studies focused on detecting patterns in the history of code clones to evaluate the harmfulness of clones. Since clone evolution is a rather novel field of study, there is still need for more comprehensive models and improved methodologies. Current approaches are limited to...

background: alkyl hydroperoxide reductase (ahpc) of helicobacter pylori is considered as a diagnostic antigen. there­fore, this antigen can be used to detect h. pylori infection by stool immunoassays such as elisa. the aim of this study was to simplify the ahpc protein purification procedures. methods: for whole cell protein extraction, the bacterial cells were ruptured by octly-β-d glucopyrano...
