A gain-scheduling approach for the control of geometrically nonlinear structures is developed. The objective is to improve performance over current linear design techniques that are applied to the same control problem. The ...

Computer aided design has allowed many design decisions to be made before hardware is built through "virtual" prototypes: computer simulations of an engineering design. To produce robust systems noise factors must also be ...

Conflict-directed search algorithms have formed the core of practical, model-based reasoning systems for the last three decades. In many of these applications there is a series of discrete constraint optimization problems ...

As the scale of space exploration gets larger, planning of planetary surface exploration becomes more complex and campaign-level optimization becomes necessary. This is a challenging profit maximization problem whose ...

Real options analysis is being increasingly used as a tool to evaluate investments under uncertainty; however, traditional real options methodologies have some shortcomings that limit their utility, such as the use of the ...

An approach utilizing cognitive support tools is presented with the purpose of improving upon the generation of quality software requirement specifications. Based on successful tools in product development and cognitive ...

Correct modeling of the space environment, including radiative forces, is an important aspect of space situational awareness for geostationary (GEO) spacecraft. Solar radiation pressure has traditionally been modeled using ...

In the recent few years, there has been an observed trend of US legacy carriers putting more emphasis on international traffic than domestic, i.e. expanding international capacity while decreasing their domestic capacity. ...
