1. 1. Managing Geometrical Variation through Optimization and Visualization

   Författare :Johan Lööf; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; variation simulation; tolerancing; Tolerance allocation; locating scheme optimization; geometry assurance; visualization of variation; tolerance analysis;

   Sammanfattning : All manufacturing processes are afflicted by variation that causes deviations in critical dimensions in the final product. Geometrical variation results in form and size deviation in individual parts. Assembly variation comes from defects in assembly equipment, and influence how parts are mounted together. LÄS MER

3. 2. Crossing the threshold : Visualization design and conceptual understanding of evolution

   Författare :Andreas C. Göransson; Lena Tibell; Konrad Schönborn; Anat Yarden; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Evolution; Natural selection; Visualization; Conceptual understanding; Conceptual change;

   Sammanfattning : The theory of evolution is considered the unifying theory of biology. An accurate understanding of evolution is vital both for the understanding of diverse topics in biology, but also for societal issues such as antibiotic resistance or biodiversity. LÄS MER

4. 3. Managing Geometrical Variation in Complex Assemblies through Visualization and Tolerance Allocation

   Författare :Johan Lööf; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tolerance analysis; and motion envelope.; variation simulation; tolerance allocation; visualization;

   Sammanfattning : To stay competitive in the market today, manufacturing companies have to shorten their time to market. This implies that time also has to be saved during the product development phase. This thesis will mainly focus on how to be more efficient in the detail design phase through different design activities. LÄS MER

5. 4. Towards Efficient Evaluation of Impacts of Geometrical Variation on Perceived Quality in Early Phases

   Författare :Ola S Wagersten; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Perceived Quality; variation simulation; visualization and evaluation; Geometrical variation; geometry assurance; non-rigid; tolerance analysis; product development;

   Sammanfattning : In a perfect world, manufacturing would lead to components without geometrical variation. This would mean that every component produced in a series would have the exact same dimensions and, when observed by a trained eye, look exactly identical. However, the world is not perfect and neither are manufacturing processes. LÄS MER

7. 5. Multidimensional MRI of Cardiac Motion : Acquisition, Reconstruction and Visualization

   Författare :Andreas Sigfridsson; Hans Knutsson; Stefan Skare; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MRI; cardiac; motion; reconstruction; Image analysis; Bildanalys;

   Sammanfattning : Methods for measuring deformation and motion of the human heart in-vivo are crucial in the assessment of cardiac function. Applications ranging from basic physiological research, through early detection of disease to follow-up studies, all benefit from improved methods of measuring the dynamics of the heart. LÄS MER
