Simultaneous Design of Communication Strategies and Control Policies in Stochastic Systems
We consider the problem of simultaneously designing communication strategies and control policies in decentralized stochastic systems. Such problems are difficult to solve, mainly because of the nonclassical nature of their information structure. We have identified classes of such problems with …

Simultaneous structural/acoustical design of composite panels
… heavier acoustical treatments. A sequential design approach of addressing first structural and then acoustical design does not take advantage of structural/acoustical coupling. A simultaneous approach is expected to help minimize the total sidewall mass. This thesis uses numerical …

Active damping of a structure with low-frequency and closely- spaced modes: experiments and theory
… is also obtained for theoretical results in the simultaneous design of a structure and control system. A spatial filtering method for determining the modal response of the structure from the physical response is also investigated.

Multiobjective collaborative optimization of systems of systems
Concept studies for warship designs typically focus on ship performance characteristics by setting design goals for such things as speed, range, and cost. However, warships generally operate as part of a larger battle or strike group. Therefore, the designs should be evaluated as part of a system …

Multidisciplinary optimization of high-speed civil transport configurations using variable-complexity modeling
… placement are described. Variable-complexity design strategies are used to combine conceptual and preliminary-level design approaches, both to preserve interdisciplinary design influences and to reduce computational expense. The preliminary-design-level analysis methods used to estimate …

Design and optimization of imaging systems by engineering the pupil function
… that the ability to accurately and efficiently design an imaging system for a specific application will be of increasing importance in the coming decades. Applications of imaging systems range from simple photography to advanced lithography machines. Perhaps the most important way to make an …

Beyond the Brick: Collaborations with a Sensing Microbial System in the Built Environment
… ecosystems over billions of years. At present, designers have made efforts to reduce our dependency on carbon-intensive resources by integrating living organisms into the built environment using biomaterials. However, difficulties keeping organisms alive have reduced their implementation to mere …

Constrained Control of Complex Helicopter Models
… The linearized models are first used for the design of variance constrained controllers with inequality constraints on outputs or inputs, output variance constrained controllers (OVC) and input variance constrained controllers (IVC), respectively. The linearized helicopter models are also used …

Transforming shape: a simultaneous approach to the body, cloth and print for garment and textile design (synthesising CAD with manual methods)
Printed textile and garment design are generally taught and practised as separate disciplines. Integrated CAD software enables textile and clothing designers to envisage printed garments by assimilating graphic imagery with 2D garment shapes, and 3D visualisations. Digital printing can be enlisted …

Plantwide Control System Design for IGCC Power Plants with CO2 Capture
In this paper, a systematic approach to design the control system of a commercial-scale integrated gasification combined cycle (IGCC) power plant with CO2 capture is considered. The control system design is developed with the objective of optimizing a desired scalar function while satisfying …

Grammatical design with graphic statics : rule-based generation of diverse equilibrium structures
During early stages of design, an architect tries to control space by "finding a form" among countless possible forms, while an engineer tries to control forces by "form-finding" an optimized solution of that particular form. Most commonly used parametric tools in architectural design provide the …

Modeling, optimization, and sensitivity analysis of a continuous multi-segment crystallizer for production of active pharmaceutical ingredients
… literature results. Through the use of a novel simultaneous design and control (SDC) methodology, we have further optimized the flowrates and crystallizer geometry in tandem.^ We have further investigated the robustness of this process and observe significant sensitivity to error in antisolvent …

Methods for the integrated design of viscoelastic materials and structural geometry
Design engineers have traditionally selected simple materials, including linear elastic solids and Newtonian fluids, for their designs, and optimize designed systems within the limitations of preselected materials. However, allowing complex materials (e.g., viscoelastic materials and soft solids) …

Synthesis of integrated solar thermal networks for domestic and industrial utilization
… Integer Non-Linear Programming (MINLP) based design and optimization methods for integrating solar thermal with domestic and industrial heat networks over multiple time frames based on discrete time intervals/periods. The study also presents a new simultaneous multi-period modelling and design …
