1. 16. Observing Sea Level Using Reflected Global Navigation Satellite System Signals

   Författare :Johan Löfgren; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; tide gauge; Global Navigation Satellite Systems; ocean tides; reflected signals; sea-level monitoring;

   Sammanfattning : Sea-level rise due to global warming is predicted to have a large impact on human society, especially for populations living in coastal regions and on islands. It is therefore of great importance to monitor the sea level and to increase the understanding of the local hydrodynamic and meteorological responses to a global sea-level rise. LÄS MER

3. 17. Spectral Mammography with X-Ray Optics and a Photon-Counting Detector

   Författare :Erik Fredenberg; Mats Danielsson; Björn Cederström; Jeffrey H. Siewerdsen; KTH; []

   Sammanfattning : Early detection is vital to successfully treating breast cancer, and mammography screening is the most efficient and wide-spread method to reach this goal. Imaging low-contrast targets, while minimizing the radiation exposure to a large population is, however, a major challenge. LÄS MER

4. 18. Managerial practices for open innovation collaboration: Authoring the spaces "in-between"

   Författare :Anna Yström; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; managerial practice; action research; innovation management; collaborative advantage; longitudinal case study; Open innovation;

   Sammanfattning : Open innovation was introduced in 2003 as a new business model for how to transfer ideas or competence across organizational boundaries. Making this shift from closed to open innovation processes is argued to offer the possibility of creating and developing technology, services and processes in new ways. LÄS MER

5. 19. Qualification Aspects in Design for Additive Manufacturing : A Study in the Space Industry

   Författare :Christo Dordlofva; Anna Rönnbäck Öhrwall; Peter Törlind; Ola Isaksson; Carolyn Conner Seepersad; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive Manufacturing; Design for Additive Manufacturing; Qualification; Design for Qualification; Space Industry; Produktinnovation; Product Innovation;

   Sammanfattning : The aim of this research is to further the understanding of implications for product development and qualification when introducing additive manufacturing (AM) in the context of the space industry. Increased availability of AM machines and alluring potentials such as design freedom and cost-efficient product development and manufacturing has led to a rapid growth in the use of AM.

7. 20. Navigating Sustainability Transformations: Backcasting, transdisciplinarity and social learning

   Författare :Johan Holmén; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; backcasting; transformations; systems change; social learning; Education for Sustainable Development ESD ; Sustainability; transitions; reflexive governance; transdisciplinarity;

   Sammanfattning : Complex and persistent sustainability challenges necessitate transformations into futures that are fundamentally different to what was before. Such change processes cannot be planned in traditional ways; they require reflexive modes of governing where we collectively learn how to navigate uncharted terrain while exploring it. LÄS MER
