  1. 1. Statistical modeling and design in forestry : The case of single tree models

    Författare :Leakemariam Berhe; Göran Arnoldsson; Göran Broström; Dieter Rasch; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Forest data; Covariance structures; Nonlinear mixed effects models; Tree taper models; Ds-optimal design; Replication-free design.; Statistics; Statistik;

    Sammanfattning : Forest quantification methods have evolved from a simple graphical approach to complex regression models with stochastic structural components. Currently, mixed effects models methodology is receiving attention in the forestry literature. LÄS MER

  2. 2. Innehållsdesign : Principer, metoder och verktyg samt tillämpningar inom utbildningshistorisk forskning och undervisning

    Författare :Monica Langerth Zetterman; Donald Broady; Matthew James Driscoll; Uppsala universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Education; Text Encoding Initiative; markup; markup languages; text encoding; history of education; prosopography; educational science; educational uses; methods in education; methodology; historical sources; digital collection; collective biography; electronic texts; Pedagogik; Pedagogik; Education;

    Sammanfattning : This thesis explores content design – an area which encompasses the practices and the conceptions of the description, organisation and manipulation of digital content. The overall aim was to identify and examine principles, methods and tools appropriate for content design within the humanities and the social sciences. LÄS MER

  3. 3. On Structural Design of High-Speed Craft

    Författare :Mikael Razola; Jakob Kuttenkeuler; Anders Rosén; Olav Fredrik Rognebakke; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slamming; high-speed craft; finite-element analysis; design methods; experimental analysis; numerical simulations; design loads; statistical analysis;

    Sammanfattning : The development in structural design and construction of high-speed craft has been extensive during the last decades. Environmental and economical issues have increased the need to develop more optimized structures, using new material concepts, to reduce weight and increase performance efficiency. LÄS MER

  4. 4. Synthesis of well arrayed structures with assistance of statistical experimental design

    Författare :Yajuan Cheng; Pär Jösson; Zhe Zhao; Gunnar Westin; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimization; experimental design; statistical analysis; monolayer arrays of silica spheres; vertically aligned ZnO rod arrays; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : During the synthesis of well arrayed nano/micro structures through wet chemical methods, plenty of parameters are usually involved. Consequently, it is extremely time- and cost-consuming to find out the optimized synthesis conditions by using the conventional "changing one separate factor at a time" (COST) strategy. LÄS MER

  5. 5. Product-Service System Designing for Environmental Sustainability : Insights into Design Cognition of Experienced Product Developers

    Författare :Abhijna Neramballi; Tomohiko Sakao; Mattias Lindahl; Laura Hay; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design cognition; Product-service system designing; Product designing; Design support; Design for environmental sustainability.;

    Sammanfattning : The overall objective of this research is to support practitioners within the manufacturing industry to effectively design product-service system (PSS)-based solutions with relatively lower environmental impacts than typical product-centric solutions. Design research methodology (DRM) is applied to systematically address this objective with both descriptive and prescriptive approaches. LÄS MER
