Customer-led conceptual design system
… at carrying out a feasibility study for the design of a Customer-Led Design (CLD) system that will allow individuals or users with little or no technical know-how of engineering design but with an idea of what they want to bring the idea into reality through the customer driven-design system. …

Conceptual design of wave energy converters
… has yet to gain commercial success due to the design space being divergent. To facilitate convergence, this dissertation has proposed a method using the mechanical circuit framework to transform a linear representation of any wave energy converter into an equivalent single body absorber, or …

A conceptual design analysis of Git
… on the quality of the concepts that underlie its design. Yet this hypothesis has not been systematically explored by researchers, and conceptual design has not played the central role in the research and teaching of software engineering that one might expect. As part of a new research project to …

Conceptual design of suspended structural systems
… structural systems. This is done by performing a conceptual design for the proposed new Civil and Environmental Engineering building at the Massachusetts Institute of Technology. It begins with site considerations and owner requirements and progresses through the concept development and design …

Geometric abstractions for conceptual design support
Thesis (Ocean. E.)--Massachusetts Institute of Technology, Dept. of Ocean Engineering, 1994, and Thesis (M.S.)--Massachusetts Institute of Technology, Dept. of Civil Engineering, 1994.

Emotive implications of rendering in conceptual design
… research into the role emotions play in designing. Rendering enables the visualisation of conceptual models by providing graphical presentation of design concepts. Such a presentation can convey not only object information but also emotive information and can evoke human emotive …

Structural systems and conceptual design of cantilevers
… form and create unique feature spaces. From a design perspective, cantilevers are amazing feats for the built environment, and structurally, present many opportunities. However, conceptual cantilever design can be a difficult task for Architects and Structural Engineers because there are many …

Inlet drag prediction for aircraft conceptual design
… ACSYNT, a computer program for aircraft conceptual design, has necessitated the development of methods for predicting inlet drag. Originally, the drag of only one inlet type, the variable-geometry conical inlet, could be calculated within ACSYNT. This prompted the present research which …

Control authority assessment in aircraft conceptual design
… by control authority. Thus, it is essential for designers to evaluate a candidate concept's control authority early in the conceptual design phase. In this thesis, a methodology for rapid control power evaluation of preliminary design configurations against requirements at the key flight …

Landing gear integration in aircraft conceptual design
The design of the landing gear is one of the more fundamental aspects of aircraft design. The design and integration process encompasses numerous engineering disciplines, e.g., structure, weights, runway design, and economics, and has become extremely sophisticated in the last few decades. Although …

A PHIGS-based spreadsheet for conceptual design
There are several computer aided design systems which exist to aid the conceptual phase of design. These CAD systems provide adequate geometry input, but often lack the capability to interactively obtain large amounts of numerical and text input often needed by analysis software. An interactive …

Programming and Conceptual Design Using Building Information Modeling
… Modeling (BIM) during the programming and conceptual design phase of a project. The research was based on a case study undertaken dealing with the decisions and assumptions made during the design phases of the Center for Science at Cal Poly San Luis Obispo. The project team used a …

Conceptual Design for a Laminar-Flying-Wing Aircraft
… a relatively straightforward initial step is the conceptual design of a version with restricted sweep angle. Such a design is the topic of this thesis. In addition to boundary layer laminarisation (utilising distributed suction) and limited sweep, a standing-height passenger cabin and subcritical …

Mathematical Formulations in Conceptual Design, Analysis, and Optimization
Engineering design problems are often multidisciplinary in nature, giving them a natural decomposition into subproblems. The field of multidisciplinary design, analysis, and optimization (MDAO) has developed methods to integrate these sub-problems and generate standardized mathematical …

Conceptual design of nuclear systems for hydrogen production
Demand for hydrogen in the transportation energy sector is expected to keep growing in the coming decades; in the short term for refining heavy oils and in the long term for powering fuel cells. However, hydrogen cannot be harvested from natural sources like other fuels, it must be industrially …

Conceptual Design of a Nuclear Microreactor Transportation Cask
… demonstrated using a sample microreactor core design with heat pipes. An adequate shutdown reactivity margin (k_{eff} < 0.95) can be maintained using the control drums and shutdown rods except if the heat pipes are broken open and flooded with water. Shielding the gamma radiation so that the …
