1. 21. Topics in Dynamic Spectrum Access : Market Based Spectrum Sharing and Secondary User Access in Radar Bands

   Författare :Miurel Tercero Vargas; Jens Zander; Mikael Prytz; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; spectrum sharing; radar band; cognitive radio; Telecommunication; Telekommunikation; Systems engineering; Systemteknik;

   Sammanfattning : The steady growth in demand for spectrum has increased research interest in dynamic spectrum access schemes. This thesis studies some challenges in dynamic spectrum access based on two strategies: open sharing and hierarchical access. LÄS MER

3. 22. Kroppar under träd – en miljö för konstnärlig forskning

   Författare :Henric Benesch; Göteborgs universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Artistic Research; Architecture; Change; Doxa; Environment; Heuristics; Space; Poetics; Doxa;

   Sammanfattning : This dissertation in the field of artistic research is an articulation, in words and images, on the experience of working with a notional environment for artistic research. It is not a reflection on or a description of the process which the work has involved, but above all an articulation, characterisation and development, in words and images, of the conceptual and pictorial world constituted during, through and in the course of the actual work on an environment for artistic research in Vasaparken, Göteborg.

4. 23. The visible patient. Hybridity and inpatient ward design in a Namibian context

   Författare :Catharina Nord; KTH; []
   Nyckelord :architectural theory; hospital design; healthcare building design; inpatient ward design; hybridity; embodiment; illness and disease; illness experience; patient-focused design; patient-centred design; healing environment; therapeutic environment; gl; SOCIAL SCIENCES;

   Sammanfattning : Even if one is confident that the staff provide the bestpossible treatment, being admitted into hospital is still astressful situation. In recent decades, architecturalresearchers have elaborated on aspects of the patient'sperspective where the design of the physical environment maypositively enhance the healing experience. LÄS MER

5. 24. White Layer Formation during Hard Turning of Through-Hardened Martensitic and Bainitic AISI 52100 Steel

   Författare :Seyed Hosseini; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; white layers; residual stresses; phase transformation; dynamic recovery; bainite; dynamic recrystallization; carbide deformation; retained austenite; steel; martensite;

   Sammanfattning : Increased demands for flexible manufacturing lines, shorter cycle times and reduced impact on the environment drives the need for optimization of today’s manufacturing. For machining of hardened steel parts (>45 HRC), grinding has been the obvious choice for many decades. However, hard turning has often been considered as a replacement due to e. LÄS MER

7. 25. Entering the dynamic risk space : Assessing planetary boundary interactions through process-based quantifications

   Författare :Arne Tobian; Johan Rockström; Sarah Cornell; Ingo Fetzer; Dieter Gerten; Martin Volk; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Planetary boundaries; climate change; land-use change; Earth system interactions; ecosystem modeling; green water; vetenskap om hållbar utveckling; Sustainability Science;

   Sammanfattning : The planetary boundaries framework is an effort to define a safe operating space for humanity. Its rationale is that sustainable development needs to be achieved in ways that safeguard the stability of the Earth system on which human prosperity relies. LÄS MER
