    Natural Parameterization

    The objective of this project has been to develop an approach for imitating physical objects with an underlying stochastic variation. The key assumption is that a set of “natural parameters” can be extracted by a new subdivision algorithm so they reflect what is called the object’s “geometric DNA”. A case study on one hundred wheat grain crosssections (Triticum aestivum) showed that it was possible to extract thirty-six such parameters and to reuse them for Monte Carlo simulation of “new” stochastic phantoms which possessthe same stochastic behavior as the “original” cross-sections

    Incremental value of advanced cardiac imaging modalities for diagnosis and patient management : focus on real-time three-dimensional echocardiography and magnetic resonance imaging

    Advanced cardiac imaging modalities play a crucial role in the diagnostic process and clinical management of patients with different cardiac diseases, including heart failure, valvular heart disease, myocardial infarction and atrial fibrillation. RT3DE has made an important transition from a research tool to a clinically applicable imaging technique and has been demonstrated to provide important advantages over conventional 2D echocardiography, such as a more accurate quantification of cardiac chamber size and function and the possibility of unlimited image plane orientations for better understanding of valvular heart diseases. Contrast-enhanced echocardiography should be performed in every patient with suboptimal acoustic window, especially with RT3DE. Importantly, in patients underwent primary percutaneous coronary intervention, perfusion analysis can provide an accurate estimate of myocardial infarction size, which is crucial information for the patient management, together with more sophisticated assessment of LV mechanics. Myocardial deformation imaging has witnessed an enormous development in the last years and is now considered an accurate tool for a more sensitive assessment of LV regional and global function and for a more detailed assessment of LV mechanics and dyssynchrony. CMR represents the reference imaging modality for the quantification of LV volumes and function and for the identification of myocardial scar/fibrosis. It should be therefore considered for a comprehensive evaluation of heart failure patients, including more novel and sophisticated assessments of transvalvular flow and LV dyssynchrony. Advanced cardiac imaging modalities can be applied in heart failure patients referred for CRT to explore novel physiopathological aspects, such as the effect on LV rotation mechanics, on functional mitral regurgitation and cerebral blood flow.Philips Healthcare, Meda Pharma, Boehringer Ingelheim, Roche, Servier, Biotronik, Boston Scientific Nederland BV and ServierUBL - phd migration 201

    Designing Atmospheres: Theory and Science

    Get PDF
    This book was born as the legacy of the “Designing Atmospheres: Theory and Science” Symposium, an Interfaces event of the Academy of Neuroscience for Architecture (ANFA), sponsored by the EU’s Horizon 2020 MSCA Program — RESONANCES Project, the Perkins Eastman Studio, and the Architecture Department at Kansas State University. The event was hosted in the College of Architecture, Planning and Design (APDesign), Kansas State University (K-State), Manhattan, KS, on March 28, 2023. Recent advances in science confirm many of the architects’ deep-rooted intuitions, improving knowledge about the perception of space and the meaning of architectural and urban design. This volume collects four essays: “Investigating Atmosphere in Architecture: An Overview of Phenomenological and Neuroscientific Methods” by Elisabetta Canepa; “Rhythms of the Brain, Body, and Environment: A Neuroscientific Perspective on Atmospheres” by Zakaria Djebbara; “A History of Tool-Atmospheres” by Kory Beighle; and “Atmospheric Histrionics” by Harry Francis Mallgrave. Bob Condia provided a critical introduction entitled “The Design of Atmospheres.”https://newprairiepress.org/ebooks/1050/thumbnail.jp

    A systematic approach for integrated product, materials, and design-process design

    Designers are challenged to manage customer, technology, and socio-economic uncertainty causing dynamic, unquenchable demands on limited resources. In this context, increased concept flexibility, referring to a designer s ability to generate concepts, is crucial. Concept flexibility can be significantly increased through the integrated design of product and material concepts. Hence, the challenge is to leverage knowledge of material structure-property relations that significantly affect system concepts for function-based, systematic design of product and materials concepts in an integrated fashion. However, having selected an integrated product and material system concept, managing complexity in embodiment design-processes is important. Facing a complex network of decisions and evolving analysis models a designer needs the flexibility to systematically generate and evaluate embodiment design-process alternatives. In order to address these challenges and respond to the primary research question of how to increase a designer s concept and design-process flexibility to enhance product creation in the conceptual and early embodiment design phases, the primary hypothesis in this dissertation is embodied as a systematic approach for integrated product, materials and design-process design. The systematic approach consists of two components i) a function-based, systematic approach to the integrated design of product and material concepts from a systems perspective, and ii) a systematic strategy to design-process generation and selection based on a decision-centric perspective and a value-of-information-based Process Performance Indicator. The systematic approach is validated using the validation-square approach that consists of theoretical and empirical validation. Empirical validation of the framework is carried out using various examples including: i) design of a reactive material containment system, and ii) design of an optoelectronic communication system.Ph.D.Committee Chair: Allen, Janet K.; Committee Member: Aidun, Cyrus K.; Committee Member: Klein, Benjamin; Committee Member: McDowell, David L.; Committee Member: Mistree, Farrokh; Committee Member: Yoder, Douglas P
