This paper introduces a type system for Extensible Dependency Grammar (xdg) (Debusmann et al., 2004), a new, modular grammar formalism based on dependency grammar. As xdg is based on graph description, our emphasis is on capturing the notion of multigraph, a tuple of arbitrary many graphs sharing the same set of nodes. An xdg grammar consists of the stipulation of an extensible set of parametri...
Introduction A fundamental part of aircraft design involves the wing airfoil optimization, establishing an outer shape of the wing which has good aerodynamic performance, good internal volume distribution for fuel and systems and which also serves as an efficient structural member supporting the weight of the aircraft. As for all optimization tasks, the complexity of the problem is directly cou...
A number of techniques have been developed in recent years for the analysis and design of controllers which are robust with respect to structured complex uncertainty. In particular the complex p synthesis procedure has been successfully applied to a number of engineering problems. However the presence of real parametric uncertainty in the problem description substantially complicates matters, s...
A family of digital parametric audio equalizers based on high-order Butterworth, Chebyshev, and elliptic analog prototype filters is derived that generalizes the conventional biquadratic designs and provides flatter passbands and sharper bandedges. The equalizer filter coefficients are computable in terms of the center frequency, peak gain, bandwidth, and bandwidth gain. We consider the issues ...
We utilize a high-dimensional parametric design space to support a novel and intuitive method for 3D modeling. Users visually explore the design space and pick models using a continuous, map-like interface. We leverage models created by the user community to learn underlying structure in the space via kernel density estimation. This mapping of the space is maintained by a server that synchroniz...
Parametric cost analysis uses equations to map measurable system attributes into cost. The measures of the system attributes are called metrics. The equations are called cost estimating relationships (CER's), and are obtained by the analysis of cost and technical metric data of products analogous to those to be estimated. Examples of system metrics include mass, power, failure_rate, mean_time_t...
