From the beginning of creation, human being was surrounded by nature. Everything in nature is well organized and in harmony with the other parts of it. Through the history, nature has been always a source of inspiration for the human begin in different aspects of their life. Architecture as one of the remarkable features in every society cannot be separated from nature. In architecture design...

when the orbital altitude of a small satellite is near-earth, passive stabilization can be considered. the purpose of this paper is to combine the passive gravity gradient and aerodynamic stabilization methods together so that all the three axes stabilizations can be obtained. in this regard, the set of nonlinear equations of motion will be solved numerically with specified initial condition. t...

This paper presents an approach to support computer-aided conceptual design of mechatronic assemblies in a collaborative, multi-user environment. We describe a system, Conceptual Understanding and Prototyping (CUP), that allows a team of design engineers, collaborating over the Internet, to develop a high-level structure-function-behavior (S-B-F) description of an assembly in a VRML-based virtu...

The product development process is concerned, not only with the design of products, but with how these products are manufactured, distributed and serviced. Engineering conceptual design can be de ned as that phase of the product development process during which the designer takes a speci cation for a product to be designed and generates many broad solutions to it. Each of these broad solutions ...

Conceptual design involves requirements analysis, functional specification, and architectural design. It remains informal and poorly understood. We studied the conceptual design activities of a representative industrial software project, Centauri, for three months with follow-up observations and discussions over the following six months. Our goal was to understand how patterns of collaboration ...

This paper will study various approaches to the automated design problem. It will begin with an overview of current state of the art in automated design, show examples of existing applications, determine current limitations and capabilities, explore potential applications to automating the design of spacecraft subsystems, determine difficulties towards achieving this and make recommendations as...

GIS systems often rely on low-level, pixel-based representations of satellite scenes. The purpose of this paper is to show the advantages of using an intermediate representation incorporating multiple criteria in scene characterisation, as well as a framework for monitoring changes over time based on features of interest. A Conceptual Spaces framework, in conjunction with navigation-based skele...

  In this paper, authors tackle three very important questions that need to be answered if a theory of design is to be constructed. The first is what designers do, Which we attempt to illustrate with the help of case studies and theories of design practice. The second question is what guides designers. Here, authors try to present some of the proposed normative positions about design, to show t...

Earth observation is diversifying, and now includes new types of systems, such as citizen observatories, unmanned aerial vehicles and wireless sensor networks. However, the Copernicus Programme vision of a seamless chain from satellite data to usable information in the hands of decision makers is still largely unrealized, and remote sensing science lacks a conceptual framework to explain why. T...
