This paper reports an experimental case study constructing an IP phone product line with the PLUS method. The IP phone product line equips a graphical user interface and interacts with the network. Its behavior is complicated, state dependent, and feature dependent. The original PLUS domain engineering process requires to perform dynamic interaction modeling among objects or finite state machine modeling...
In this paper, we present a problem-solving support system for mathematical sciences as a metasystem. We have implemented an integrated associative search for mathematical expressions and propose a GUI system which is suitable for use with this retrieval system. We present a prototype system with those systems we have implemented. The prototype system enables users' searching mathematical expressions...
