Politicians and engineers are increasingly realizing that values important in the development of technological artefacts. What is often overlooked different conceptualizations these abstract lead to design-requirements. For example, designing social media platforms for deliberative democracy sets us up technical work on completely types architectures mechanisms than so-called liquid or direct f...

How can you change your mind to be more open? There many sources that can help you to improve your thoughts. It can be from the other experiences and also story from some people. Book is one of the trusted sources to get. You can find so many books that we share here in this website. And now, we show you one of the best, the conceptual schema and relational database design a fact oriented appro...

Database applications are frequently faced with the necessity of representing time varying information and, particularly in the management of information systems, a few kinds of behavior in time can characterize a wide class of applications. A great amount of work in the area of temporal databases aiming at the de nition of standard representation and manipulation of time, mainly in relational ...

Designing products to fit human needs, preferences and capabilities is an essential key to competitiveness. In contested product markets, the management of user-related knowledge is therefore critical. Studies have shown that the identification and implementation of user requirements are significant issues for determining successful product development, especially during the conceptual design p...

The critical product planning phase, early in the product development cycle, requires a design tool to set engineering priorities, capable of selecting the preferred design concept and setting target levels of engineering performance to guide the later product development stages, while considering the needs of both the consumer and producer. The Quality Function Deployment (QFD) method was deve...

The early stages of engineering design are critical, as the highlevel decisions made at this point have the most impact on the final product’s design, cost, and success. However, little software is available to support engineers during the initial, conceptual design phase. In addition, at this and all other stages of design, engineers are increasingly tasked with utilizing unwieldy collections ...

Early stage design provides the greatest opportunities to explore design alternatives and perform trade studies before costly design decisions are made. The goal of this research is to develop a simulation-based framework that enables architectural analysis of complex systems during the conceptual design phase. Using this framework, design teams can systematically explore architectural design d...

background and purpose: in a recent century, the amount of construction waste has increased significantly. although the building industry has a considerable role in the development of a society, it is regarded as an environmentally destructive. source reduction is the highest goal in the waste management hierarchy and is in priority. it also has economic benefits by reducing costs associated wi...

Introduction Within the framework of its General Studies Programme (GSP), ESA performs a number of pre-Phase-A assessment studies each year. The purpose of these studies is to assess the feasibility of a new space mission from the technical, programmatic and economic points of view. This is normally achieved by producing a preliminary conceptual design of the mission and space system. The resul...
