1. 6. Risk communication in multi-stakeholder disaster risk management systems : Insights and recommendations from the Swedish system

   Författare :Lexin Lin; Avdelningen för Riskhantering och Samhällssäkerhet; []
   Nyckelord :multi-level DRM system; risk communication; Sweden; disaster risk management DRM ; risk assessment; communication challenges; ; multi-stakeholder;

   Sammanfattning : The overall purpose of this thesis is to improve our understanding of how disaster risk management (DRM) systems function. Specifically, it aims to increase our knowledge about effective communication in a multi-stakeholder, multi-level DRM system, with a particular focus on the exchange of risk-related information for risk assessment.

3. 7. 'Getting' it Together In Joint Directed Action

   Författare :Christina Mauléon; Philippe Lorino; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; emotion; interpretational-relational; language discourse; Joint Directed Action; meaning making sensemaking; quality sciences; relational landscape; identity; action.;

   Sammanfattning : This thesis is focused upon investigating how come activities in organizations are sometimes not aligned with an objective at hand, be it a project goal, safety, quality or other. When something goes wrong, where are the answers to be found? In the pursuit to examine these questions further, the aim of the thesis has been to investigate meaning making in action as this can increase an understanding of how actors may continuously align their actions, collective and/or individual, with a common goal – this process here being called Joint Directed Action (JDA).

4. 8. On the trade-off between uncertainty and delay in UWB and 5G localization

   Författare :Gabriel Garcia; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultra-wideband; MIMO; positioning; MAC delay; localization; 5G; initial access; millimeter-wave; multipleinput multiple output;

   Sammanfattning : Location-aware technologies in combination with emerging wireless communication systems have revolutionized many aspects of our daily lives by means of applications within the commercial, public and military sectors. Ultra-wideband (UWB) and 5G stand out as emerging radio frequency (RF) based technologies that tackle the limitations of Global Positioning System solutions. LÄS MER

5. 9. Analytical Approaches to Load Modulation Power Amplifier Design

   Författare :William Hallberg; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; linear; load modulated balanced amplifier LMBA ; Active load-pull; radio frequency RF ; Wilkinson power divider.; load modulation; energy efficiency; microwave; power amplifier PA ; Doherty;

   Sammanfattning : In future mobile communication networks, there will be a shift toward higher carrier frequencies and highly integrated multiple antenna systems. The system performance will largely depend on the available radio frequency (RF) hardware. As such, RF power amplifiers (PAs) with improved performance, e.g. LÄS MER

7. 10. Accuracy and Delay: An Inherent Trade-off in Cooperative UWB Navigation

   Författare :Gabriel Garcia; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; positioning; Ultra-wideband; navigation; MAC delay; localization.; S-TDMA;

   Sammanfattning : Location-aware applications and wireless sensor networks are becoming essential in our daily lives from a commercial, and public perspectives. The need of localization information to drive the applications is a key requirement. New technologies have emerged to tackle the problem of the limitations of the Global Positioning System (GPS) solutions. LÄS MER
