  2. 1. On subscale flight testing : Cost-effective techniques for research and development

    Author : Alejandro Sobrón Rueda; Petter Krus; David Lundström; Mirko Hornung; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Experiments with downscaled or subscale physical models have traditionally been an essential source of information in aerospace research and development. Physical models are very effective at revealing unforeseen issues and providing confidence in design predictions or hypotheses. READ MORE

  4. 2. On Subscale Flight Testing : Applications in Aircraft Conceptual Design

    Author : Alejandro Sobron; Petter Krus; David Lundström; Zdobyslaw Goraj; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Downscaled physical models, also referred to as subscale models, have played an essential role in the investigation of the complex physics of flight until the recent disruption of numerical simulation. Despite the fact that improvements in computational methods are slowly pushing experimental techniques towards a secondary role as verification or calibration tools, real-world testing of physical prototypes still provides an unmatched confidence.

  5. 3. Aircraft Design Automation and Subscale Testing : With Special Reference to Micro Air Vehicles

    Author : David Lundström; Petter Krus; Jean- Marc Moschetta; Linköpings universitet; []
    Keywords : ;

    Abstract : This dissertation concerns how design automation as well as rapid prototyping and testing of subscale prototypes can support aircraft design. A framework for design automation has been developed and is applied specifically to Micro Air Vehicles (MAV). READ MORE

  6. 4. On Computational Homogenization of Flow in Porous Media

    Author : Carl Sandström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiscale; porous media; stokes flow; FE2; computational homogenization; darcy flow;

    Abstract : Porous materials are present in many natural as well as engineered structures. Engineering examples of porous materials include sandstone in which oil can be stored, earth dams, composite materials, air filters and sanitary products with fiber networks (e.g. diapers). READ MORE

  7. 5. Individuals with autism spectrum disorders : teaching, language, and screening

    Author : Fredrika Miranda-Linné; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Autism; autism spectrum disorders; Autism Behavior Checklist; language; test construction; factor analysis; teaching; discrete-trial; incidental teaching; generalization; spontaneous usage; Psykologi; Psychology; Psykologi; Clinical Physiology; klinisk fysiologi;

    Abstract : The present dissertation on autism spectrum disorders (ASD) addressed several questions. First, the behavioral symptoms of speaking and mute individuals with ASD were compared on the Autism Behavior Checklist (ABC), a commonly used diagnostic instrument. In addition, questions about the construction of the ABC were investigated. READ MORE
