Graphitic Structures by Design
Langmuir, 2006It is shown that self-supporting graphitic structures of specific shape can be grown in a variety of forms, from nanoscale to macroscale, on metal templates, in a fuel-rich mixture of ethylene and oxygen at temperatures between 750 and 900 K. The evidence presented suggests graphite can be grown in any shape created from catalytic metals (e.g., Ni ...

Designing inflatable structures
ACM Transactions on Graphics, 2014We propose an interactive, optimization-in-the-loop tool for designing inflatable structures. Given a target shape, the user draws a network of seams defining desired segment boundaries in 3D. Our method computes optimally-shaped flat panels for the segments, such that the inflated structure is as close as possible to the target while satisfying the ...

AbstractCurrent processes for design and detailing in structural engineering are often broken up into a sequence of partial processes because of the complexity of the problem. But sequential additions of separate solutions rarely lead to an optimal design.

The designability of protein structures
Journal of Molecular Graphics and Modelling, 2001It has been noted that natural proteins adapt only a limited number of folds. Several researchers have investigated why and how nature has selected this small number of folds. Using simple models of protein folding, we demonstrate systematically that there is a "designability principle" behind nature's selection of protein folds. The designability of a

Structured design for structured computer architecture
ACM SIGARCH Computer Architecture News, 1975Complexity and technological maturity characterise contemporary computer systems. A good way to master complexity is to proceed by hierarchisation. Hierarchisation of the activities implemented implies that those of high level control those of lower level.

AbstractAlthough overlaying code segments is a very old technique, there is very little literature 68 on what the ground rules are, what the options are and how to select an overlay structure. As a result, the facilities provided by most linkage editors are much poorer than they need be.

ACM SIGAPL APL Quote Quad, 1978
A Structured APL language (SAPL) is suggested to provide structured programming in APL. The feature of SAPL is an APL preprocessor that interprets Edsger Dijkstra's IF-FI and DO-OD structured program constructs to achieve program flow in APL. The flavor of SAPL is given in several examples.

SIAM Journal on Algebraic Discrete Methods, 1980
It is possible to view the combinatorial structures known as (integral) t-designs as $\mathbb{Z}$-modules in a natural way. In this note we introduce a polynomial associated to each such $\mathbb{Z}$-module. Using this association, we quickly derive explicit bases for the important class of submodules which correspond to the so-called null-designs.

INTERACT '93 and CHI '93 conference companion on Human factors in computing systems - CHI '93, 1993
The paper outlines the coarse structure, called CO-SITUE, of the design space in which designer reasoning takes place. It appears that any account of design rationale or of the logic of design reasoning will have to assume a CO-SITUE -like framework. As a frame notation, CO-SITUE has been applied in analysing and recording a medium-scale design project.

On the design of structured controllers
2001 European Control Conference (ECC), 2001In this paper we consider the problem of minimizing the H ∞ -norm of the sum of two systems which are interconnected with two different controller components. We sketch two specific applications of this decentralized control problem. As the main contribution, we reveal that this structured controller design problem admits a full LMI solution if only ...
