2. 1. Communicating climate action : Combining action repertoires and linguistic repertoires in social movement message construction

   Author : Sol Agin; Michael Karlsson; Emilia Ljungberg; John Lynch; Ulrika Olausson; Karlstads universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; climate change communication; social movements; communicative action repertoire alignment; emotional appeals; threat perception; Media and Communication Studies; Medie- och kommunikationsvetenskap;

   Abstract : The climate crisis is one of the largest global challenges that humanity has ever faced. Despite the scientific consensus on the threat, action is not occurring on the pace or level needed to stave off the consequences. READ MORE

4. 2. Robust Low-Cost Multiple Antenna Processing for V2V Communication

   Author : Chouaib Bencheikh Lehocine; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Directional antennas; Beamforming; Multiple antennas; Periodic communication; Broadcast V2V communication; Hybrid combining;

   Abstract : Cooperative V2V communication with frequent, periodic broadcast of messages between vehicles is a key enabler of applications that increase traffic safety and traffic efficiency on roads. Such broadcast V2V communication requires an antenna system with omnidirectional coverage, which is difficult to achieve using a single antenna element. READ MORE

5. 3. RF Wireless Power Transfer for IoT Applications

   Author : Morteza Tavana; Emil Björnson; Jens Zander; Ayça Özçelikkale; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronic waste; Energy harvesting; Internet of things; transceivers; wireless power transfer; wireless sensor networks; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : With the emergence of the Internet of things (IoT) networks, the replacement of batteries for IoT devices became challenging. In particular, the battery replacement is more expensive and cumbersome for scenarios where there are many IoT devices; or where the IoT devices are in unreachable locations; or when they have to be replaced often.

6. 4. Massive MIMO for Dependable Communication

   Author : Sara Willhammar; Kommunikationsteknologi; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Channel characterisation; Channel measurements; Channel modeling; Industrial automation; Industry 4.0; Internet-of-Things; Massive MIMO; mMTC; Reliability; URLLC;

   Abstract : Cellular communication is constantly evolving; currently 5G systems are being deployed and research towards 6G is ongoing. Three use cases have been discussed as enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), and ultra-reliable low-latency communication (URLLC). READ MORE

7. 5. Over-the-Air Computation for Machine Learning: Model Aggregation via Retransmissions
