Optimal structures and collective dynamics of human flows in transportation networks.
This thesis explores the dynamical and structural properties of human mobility within urban environments through the lens of complex systems and network science. Beginning with an introduction to the relevance of studying cities and human mobility, we outline our aim to investigate the interplay …

Structural optimization: from continuum and ground structures to additive manufacturing
This work focuses on optimal structural systems, which can be modeled using discrete elements (e.g. slender columns and beams), continuum elements (e.g. walls or slabs), or combinations of these. Optimization problems become meaningful only after the objective function, or benchmark, that evaluates …

Optimal capacity adjustment for supply chain control
… research is to analytically determine simple structures to adjust capacity that require minimal computational resources and are relatively easy to implement. The research focuses on manufacturing companies that operate a make-to-order environment in which there is no inventory of finished …

Mathematical Formulations in Conceptual Design, Analysis, and Optimization
… elementary functions with highly heterogeneous structures, multiple decompositions are often possible. Furthermore, the decompositions often involve inversions of the elementary functions, leading to a restructuring of the design equations. Applying MDAO methods to specific decomposition choices …

Predicted Redidual Strength of Damaged IsoTruss® Structures
… in traditional single and hybrid-grid IsoTruss® structures. Residual strength was studied for structures subjected to axial compression, torsion and flexural bending, independently. Carbon/epoxy material properties were applied in all load cases, and fiberglass/epoxy material properties were also …

Designing A Calibration Set in Spectral Space for Efficient Development of An NIR Method For Tablet Analysis
… model.</p> <p>It was also demonstrated that the optimal structures of calibration sets are different between NIR and Raman spectroscopy for the same tablet formulation. The optimum calibration structures are also different between two APIs for the same spectroscopic technique, indicating the …

Building science through topology optimization
… of high-rise buildings and other architectural structures are given to show the importance and relevance of this approach to the structural design industry. Finally, to better understand the geometries derived throughout the thesis, optimal structures are explored in more detail using the …

Advanced tools for RNA secondary structure analysis
… the predictions, but still the calculated optimal structure is not guaranteed to correspond to the native one. In this case, and due to the fact that the native structure is feasible under the energy model, it is common practice to additionally calculate suboptimal structures and …

Spectral Optimization Problems Controlling Wave Phenomena
… of the Payne-Pólya-Weinberger ratio. The optimal values of these ratios and regions for which they are attained, for n ≤ 13, are presented and interpreted as a study of the range of the Dirichlet-Laplacian eigenvalues. For both spectral functions and each n, the optimal region has …
