Deployable structures inspired by the origami art

Thesis (M.Arch.)--Massachusetts Institute of Technology, Dept. of Architecture, 2004.Includes bibliographical references (p. 60-63).My thesis is an exploration of design methods and tools using origami as a vehicle to test their usefulness and coming to terms with their limitations. I have taken my fascination with a particular development in origami and put my belief in its potential for architectural application to the test by way of various investigations: materials and structural analysis, mathematical reasoning, manipulating space and form, parametric modeling, fabrication, and finite element testing. Parting from conventional, figural forms, mathematicians developed open-surface forms together with theorems that governed the ability of these folded forms to fold flat. I selected a particular form, the Kao-fold, for its simplicity, beauty, and structural properties and imagined many exciting possibilities, specifically for its application in designing a deployable structure. I analyzed its crease pattern, exploring variations and their corresponding folded forms. Simultaneously, different material ideas for larger-scale structures were tested and a particular configuration was assessed for internal stresses and its structural stability. Its transformation from a flat sheet to a folded state was scrutinized under the lens of mathematical reasoning, namely trigonometry, by linking the acute angle of its crease pattern and the dihedral angle in its folded state to its final folded configuration. The rigidity of this investigation was offset by the freedom afforded in manipulating paper models. As such, different spatial qualities and forms were explored while addressing the issue of scale and potential applications.(cont.) The transformational characteristics discovered were digitally simulated via the construction of parametric models, which was a more controlled manipulation of the form in a virtual space. In order to go beyond the realm of representation and address real-life building issues, a temporary open-air shelter was designed and constructed in detail. The goal was to tackle the complexity of assigning materials, designing components and fabricated them. As a final endeavor, the model's construction was tested for its structural stability using a finite element software.by Ken Giesecke.M.Arch

Biomechanics

Biomechanics is a vast discipline within the field of Biomedical Engineering. It explores the underlying mechanics of how biological and physiological systems move. It encompasses important clinical applications to address questions related to medicine using engineering mechanics principles. Biomechanics includes interdisciplinary concepts from engineers, physicians, therapists, biologists, physicists, and mathematicians. Through their collaborative efforts, biomechanics research is ever changing and expanding, explaining new mechanisms and principles for dynamic human systems. Biomechanics is used to describe how the human body moves, walks, and breathes, in addition to how it responds to injury and rehabilitation. Advanced biomechanical modeling methods, such as inverse dynamics, finite element analysis, and musculoskeletal modeling are used to simulate and investigate human situations in regard to movement and injury. Biomechanical technologies are progressing to answer contemporary medical questions. The future of biomechanics is dependent on interdisciplinary research efforts and the education of tomorrow’s scientists

La tecnología Web3D permite la visualización e interacción de estos modelos en dispositivos móviles de baja potencia.Además, estas contribuciones han permitido analizar los desafíos presentados por Industry 4.0. La tesis ha contribuido a proporcionar una prueba de concepto para algunos de esos desafíos: en factores humanos, simulación, visualización e integración de modelos

Eklat : Entwerfen und Konstruieren in Lehre, Anwendung und Theorie

Das Doktorandenkolloquium „Entwerfen und Konstruieren - in Lehre, Anwendung und Theorie ist in das von der Fakultät VI neu gegründete Innovationszentrum „Gestaltung von Lebensräumen“ als Forschungscluster aufgenommen worden. Als Verbundprojekt der Disziplinen Landschaftsarchitektur, Architektur, Bauingenieurwesen, Stadt- und Regionalplanung, soll es Forum sein für inhaltliche, aber auch arbeitsorganisatorische und -praktische Probleme der Promovierenden aus den beteiligten Fachgebieten.Vor allem geht es aber auch um die aktuellen Definitionen und Bewertungen von Wissenschaft und Forschung aus dem Blickwinkel der entwurfsorientierten Disziplinen und um einen entsprechenden inhaltlichen Zuschnitt. Die Eingrenzung der Themenfelder auf den Entwurfsbereich soll sowohl gegenüber den historisch analytischen, als auch den technisch evaluierenden Forschungsthemen, die beide bereits gut vertreten sind, einen neuen Fokus setzen: Es geht um die aktuellen materiellen und ästhetischen Voraussetzungen, Strategien und Methoden der Produktion innerhalb der entwurfsorientierten Disziplinen

ENERGY CONSUMPTION OF MOBILE PHONES

Battery consumption in mobile applications development is a very important aspect and has to be considered by all the developers in their applications. This study will present an analysis of different relevant concepts and parameters that may have an impact on energy consumption of Windows Phone applications. This operating system was chosen because limited research related thereto has been conducted, even though there are related studies for Android and iOS operating systems. Furthermore, another reason is the increasing number of Windows Phone users. The objective of this research is to categorise the energy consumption parameters (e.g. use of one thread or several threads for the same output). The result for each group of experiments will be analysed and a rule will be derived. The set of derived rules will serve as a guide for developers who intend to develop energy efficient Windows Phone applications. For each experiment, one application is created for each concept and the results are presented in two ways; a table and a chart. The table presents the duration of the experiment, the battery consumed in the experiment, the expected battery lifetime, and the energy consumption, while the charts display the energy distribution based on the main threads: UI thread, application thread, and network thread
