This paper deals with the theoretical principle and optical design of a phase-shifting telescopeinterferometer. What is called a “Telescope-Interferometer” (T-I) is indeed a novel, recently proposed Wavefront Error (WFE) sensing technique, whose basic idea consists in combining the main pupil of a telescope with a second, off-axis reference arm. Then a weak modulation of the Point Spread Functi...

Conceptual Information Systems unfold the conceptual structure of data stored in relational databases. In the design phase of the system, conceptual hierarchies have to be created which describe diier-ent aspects of the data. In this paper, we describe two principal ways of designing such conceptual hierarchies, data driven design and theory driven design, and discuss advantages and drawbacks. ...

The issue in conceptual design theory is to understand the processes which lead to innovation and to create tools which generate step changes in function in an orderly and repetitious manner. Detailed form-function synthesis methods which generally follow the conceptual phase of the design process require input specifications. An extension of function logic is proposed as a means to systematica...

The ultimate goal of software design is to transform real world problems into software solutions. Architectural design is the earliest phase of this process. It is a phase in which conceptual modeling plays an important role. In conceptual modeling, designers pay more attention to accurately describing real world problems than making detailed design decisions. Object-Oriented Analysis and Desig...

2 We are here dealing with the problem of space layout planning. We present an architectural conceptual CAD approach. Starting with design specifications in terms of constraints over spaces, a specific enumeration heuristics leads to a complete set of consistent conceptual design solutions named topological solutions. These topological solutions which do not presume any precise definitive dimen...

With the advent of recent construction technologies, human civilization is striving for cost effective and time saving design solutions. Conceptual design is the first stepping stone and is arguably the most difficult wherein a tentative shape to the final design is given. High-rise buildings being an important financial enterprise as it involves enormous private and public investment and, most...
