  2. 6. Metamodel-Based Multidisciplinary Design Optimization of Automotive Structures

    Author : Ann-Britt Ryberg; Larsgunnar Nilsson; Anirban Basudhar; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multidisciplinary design optimization MDO ; metamodel; artificial neural network ANN ; support vector machine SVM ; sequential sampling; crashworthiness; automotive structure; spot weld optimization;

    Abstract : Multidisciplinary design optimization (MDO) can be used in computer aided engineering (CAE) to efficiently improve and balance performance of automotive structures. However, large-scale MDO is not yet generally integrated within automotive product development due to several challenges, of which excessive computing times is the most important one. READ MORE

  4. 7. Making sense digitally : Conversational coherence in online and mixed-mode contexts

    Author : Therese Örnberg Berglund; Patrik Svensson; Mathias Broth; Elizabeth Keating; Umeå universitet; []
    Keywords : HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Conversational coherence; context; communicative affordances; conversation analysis; multimodality; cohesion; sequential structure; attention; polyfocality; polycontextuality; English language; Engelska språket; Human communication; Kommunikation mellan människor; engelska; English;

    Abstract : Successful interaction makes sense to its participants – it is, in other words, coherent. As different resources are employed to indicate mutual orientation by showing which actions are linked and where attention is paid, coherent conversation can be said to be achieved multimodally.

  5. 8. Utilizing Problem Structure in Optimization of Radiation Therapy

    Author : Fredrik Carlsson; Anders Forsgren; Edwin Romeijn; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optimization; intensity-modulated radiation therapy; conjugate-gradient method; step-and-shoot delivery; column generation; quasi-Newton method; regularization; sequential quadratic programming; Optimization; systems theory; Optimeringslära; systemteori;

    Abstract : In this thesis, optimization approaches for intensity-modulated radiation therapy are developed and evaluated with focus on numerical efficiency and treatment delivery aspects. The first two papers deal with strategies for solving fluence map optimization problems efficiently while avoiding solutions with jagged fluence profiles. READ MORE

    Abstract : A new type of Bioelectronic Nanosensor Device with potential applications in medicine,biotechnology and environmental analysis was designed. The nanosensor is based on RISFET (Regional Ion Sensitive Field Effect Transistor) technology. READ MORE

  7. 10. View Planning and Refractive Modeling for Structure and Motion

    Author : Sebastian Haner; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer Vision; Structure and Motion; 3D Reconstruction; View Planning; Refractive Modeling;

    Abstract : This thesis presents contributions to structure-and-motion estimation, a central topic in the field of geometric computer vision. In particular, the problem of view planning is considered, and continuous and discrete optimization-based algorithms are given for how to plan the path of a sensor to its destination, while balancing the competing goals of path length and reconstruction accuracy.
