Requirements evolution is one of critical problems influencing softwareengineering activities. Despite there is much research on requirements evolution, there still lacks quantitative understanding of requirements evolution. In this paper, we quantitatively analyze requirements evolution across multiple versions of an industrial software product. Based on data of requirements evolution and defects, we analyze the relationship between requirements evolution and requirements as well as between defects and requirements evolution. We also analyze the evolution characteristics about requirements modification. Our findings include estimation of the number of defects using evolved requirements may increase accuracy of defect estimation and business rule is the most volatile part in requirements. These findings deepen our understanding of requirements evolution and can help software organizations manage requirements evolution.

Plug-in frameworks facilitate the development of customizable and extensible software, yet they often lack support for flexible and dynamic (re)configuration. We have created ***, a novel plug-in framework for plug-and-play composition. In Plux, a composer replaces programmatic composition with automatic composition. Components just specify their requirements and provisions using metadata, and the composer assembles the components guided by that metadata. This paper introduces rule-based composition behaviors, which are a means for controlling the composition process declaratively. Behavior rules constrain the composer by preventing certain operations or by triggering new ones. They help to establish a rule conformant composition state. Thereby, Plux supports developers in declarative and rule-based composition in order to minimize programming effort.
In this paper, we proposed a novel MB-OFDM UWB system, which exploits projective geometry constructed LDPC code as its channel encoding code. We emphasized on the construction of projective geometry LDPC code and the ...
