2. 16. Digital Compensation Techniques for Transmitters inWireless Communications Networks

   Author : Efrain Zenteno; Peter Händel; Magnus Isaksson; Thomas Brazil; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital compensation; MIMO; wireless communications; satellite; Volterra; Amplfiers; HW effects; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : Since they appeared, wireless technologies have deeply transformed our society. Today, wireless internet access and other wireless applications demandincreasingly more traffic. However, the continuous traffic increase can be unbearableand requires rethinking and redesigning the wireless technologies inmany different aspects. READ MORE

4. 17. Perturbed Markov Chains with Damping Component and Information Networks

   Author : Benard Abola; Sergei Silvestrov; Christopher Engström; Dmitrii Silvestrov; Anatoliy Malyarenko; Milica Rancic; Vladimir Anisimov; Mälardalens högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics Applied Mathematics; matematik tillämpad matematik;

   Abstract : This thesis brings together three thematic topics, PageRank of evolving tree graphs, stopping criteria for ranks and perturbed Markov chains with damping component. The commonality in these topics is their focus on ranking problems in information networks. READ MORE

5. 18. Decision-making strategies of internationalization under challenging times : Lessons from SMEs

   Author : Luis Oliveira; Martin Johanson; Carin Nordström; Afonso Fleury; Margaret Fletcher; Högskolan Dalarna; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Institutions; business networks; uncertainty; international market performance; internationalization speed;

   Abstract : Small and medium-sized enterprises (SMEs) are increasingly important actors of the global market and are particularly exposed to be affected in a scenario marked by an ongoing process of deglobalization and impacts of the COVID-19 pandemic. Both of these phenomena potentialize the liabilities that firms experience abroad, namely foreignness and outsidership. READ MORE

6. 19. Distributed Immersive Participation : Realising Multi-Criteria Context-Centric Relationships on an Internet of Things

   Abstract : Advances in Internet-of-Things integrate sensors and actuators in everyday items or even people transforming our society at an accelerated pace. This occurs in areas such as agriculture, logistics, transport, healthcare, and smart cities and has created new ways to interact with and experience entertainment, (serious) games, education, etc. READ MORE

7. 20. Network Optimization of Evolving Mobile Systems with Presence of Interference Coupling

   Author : Lei You; Di Yuan; Pierre Flener; Gabor Fodor; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Resource optimization; load coupling; OFDMA; NOMA; Computer Science; Datavetenskap;

   Abstract : The rapid development from 4G to 5G of mobile communications poses significant challenges in providing high rate and capacity, making it more crucial for efficient utilization of time-frequency resource via optimally configuring the network. Mathematical optimization serves as a powerful tool for addressing this type of problems. READ MORE
