  1. 1. In conversation with simulation: The application of numerical simulation to the design of structural nodal connections

    Författare :Jens Olsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; 3D Printing; Design theory; Structural design; Structural efficiency; Simulation; Peridynamics; Force flux density; Nodal connections; Conceptual design; Steel structures; Design process; Digital design;

    Sammanfattning : The thesis explores methods for integration of structural analysis, design and production in a digital design environment. The somewhat ambiguous title implies the ambition to make such integration in relation to the explorative phase of the design process which is described by Donald Schön as having a conversational character.

  3. 2. Towards Virtual Tryout and Digital Twins : Enhanced Modeling of Elastic Dies, Sheet Materials, and Friction in Sheet Metal Forming

    Författare :Johan Pilthammar; Sharon Kao-Walter; Mats Sigvant; Wolfram Volk; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sheet Metal Forming; Stamping Die; Virtual Tryout; Digital Twin; Stamping Press; Structural Analysis; Finite Element Simulation; Optimization; Digital Image Correlation; Inverse Modeling; Maskinteknik; Mechanical Engineering;

    Sammanfattning : Competition and complexity in the global car market are continuously increasing. To gain an edge in the market while making a profit, each competitor in the market needs a strong focus on technology development. Such a focus will increase the value of the product for the customers. LÄS MER

  4. 3. Improving Low-Power Wireless Protocols with Timing-Accurate Simulation

    Författare :Fredrik Österlind; Thiemo Voigt; Adam Dunkels; Per Gunningberg; Tarek F. Abdelzaher; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Low-Power Wireless Protocols; Wireless Sensor Networks; Contiki; Cooja; Simulation; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

    Sammanfattning : Low-power wireless technology enables numerous applications in areas from environmental monitoring and smart cities, to healthcare and recycling. But resource-constraints and the distributed nature of applications make low-power wireless networks difficult to develop and understand, resulting in increased development time, poor performance, software bugs, or even network failures.

  5. 4. Taming the Erratic : Representation and materialization in post-digital architectural design

    Författare :Daniel Norell; Timothy Anstey; Ulrika Karlsson; Fredrik Nilsson; Claus Peder Pedersen; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; Representation; Materialization; Post-digital; Material simulation; Chunk; Arkitektur; Architecture;

    Sammanfattning : This thesis investigates materialization and representation in contemporary architectural design practice. Due to cultural and technological shifts, the act of design is no longer squarely located in the abstract realms of drawings or digital geometries. LÄS MER

  7. 5. Reduction Techniques for Finite (Tree) Automata

    Författare :Lisa Kaati; Parosh Aziz Abdulla; Frank Drewes; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Finite automata; tree automata; bisimulation; minimization; simulation; composed bisimulation; composed simulation; Datavetenskap; Computer Science;

    Sammanfattning : Finite automata appear in almost every branch of computer science, for example in model checking, in natural language processing and in database theory. In many applications where finite automata occur, it is highly desirable to deal with automata that are as small as possible, in order to save memory as well as excecution time. LÄS MER
