3. 2. Predictor Antenna Systems: Exploiting Channel State Information for Vehicle Communications

   Författare :Hao Guo; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 6G; Beyond 5G; temporal correlation; spatial correlation; wireless backhaul; outage probability; hybrid automatic repeat request HARQ ; channel state information CSI ; throughput; integrated access and backhaul IAB ; mobile relay; predictor antenna PA ; mobility; Marcum Q-function; relay; rate adaptation;

   Sammanfattning : Vehicle communication is one of the most important use cases in the fifth generation of wireless networks (5G).  The growing demand for quality of service (QoS) characterized by performance metrics, such as spectrum efficiency, peak data rate, and outage probability, is mainly limited by inaccurate prediction/estimation of channel state information (CSI) of the rapidly changing environment around moving vehicles.

4. 3. Towards Context Information-based High-Performing Connectivity in Internet of Vehicle Communications

   Författare :Hao Guo; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temporal correlation; relay; Internet-of-vehicles IoV ; reconfigurable intelligent surface; throughput; wireless backhaul; outage probability; channel state information CSI ; 5G B5G; spatial correlation; rate adaptation; mobile relay; 6G; vehicle-to-everything V2X ; Marcum Q-function; integrated access and backhaul IAB ; predictor antenna; blockage; millimeter wave;

   Sammanfattning : Internet-of-vehicles (IoV) is one of the most important use cases in the fifth generation (5G) of wireless networks and beyond. Here, IoV communications refer to two types of scenarios: serving the in-vehicle users with moving relays (MRs); and supporting vehicle-to-everything (V2X) communications for, e.g., connected vehicle functionalities.

5. 4. Spatial diffusion of telemedicine in Sweden

   Författare :Magnus Strömgren; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Telemedicine; Spatial diffusion; Sweden; Northern Sweden; Information technology; Networks; Health care delivery;

   Sammanfattning : “Telemedicine” denotes medicine at a distance using telecommunications and information technologies. The aim of the thesis is to reveal determinants and outcomes of telemedicine diffusion—that is, the spread of telemedicine in time and space. Telemedicine is examined both at the national level and in a regional case study. LÄS MER

7. 5. Dynamics of ecological communities in variable environments : local and spatial processes

   Författare :Linda Kaneryd; Bo Ebenman; Peter Münger; Michael S. Fowler; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : The ecosystems of the world are currently facing a variety of anthropogenic perturbations, such as climate change, fragmentation and destruction of habitat, overexploitation of natural resources and invasions of alien species. How the ecosystems will be affected is not only dependent on the direct effects of the perturbations on individual species but also on the trophic structure and interaction patterns of the ecological community.
