1. 16. Simulations of Point Processes on Directed Graphs

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Stavroula Rafailia Vlachou; [2022]
   Keywords : ;

   Abstract : Simulating a point process where the events correspond to vehicle collisions on a road networkcan be quite computationally heavy due to the large number of elements that are necessary toprovide a sufficient discretization of the network. This paper aims to present a computationallyefficient solution for simulating events of a point process. READ MORE

3. 17. Access Point Selection and Clustering Methods with Minimal Switching for Green Cell-Free Massive MIMO Networks

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Qinglong He; [2022]
   Keywords : Cell-free massive MIMO; multi-objective optimization; deep reinforcement learning; AP switch ON OFF; energy efficiency; Cellfri massiv MIMO; multiobjektiv optimering; djup förstärkningsinlärning; AP switch ON OFF; energieffektivitet;

   Abstract : As a novel beyond fifth-generation (5G) concept, cell-free massive MIMO (multiple-input multiple-output) recently has become a promising physical-layer technology where an enormous number of distributed access points (APs), coordinated by a central processing unit (CPU), cooperate to coherently serve a large number of user equipments (UEs) in the same time/frequency resource. However, denser AP deployment in cell-free networks as well as an exponentially growing number of mobile UEs lead to higher power consumption. READ MORE

4. 18. Distributed Trajectories under Mobile Phone Network: Empirical Estimation on Origin-Destination Matrix and Time-inhomogeneous Simulation

   University essay from Uppsala universitet/Statistik, AI och data science

   Author : Liyuan Zhang; [2022]
   Keywords : ;

   Abstract : A trajectory is the movement of an object in space as time goes by,aka ‘spatiotemporal’. Aside from all the properties an ordinary trajectorypossesses, the primary characteristic of a distributed trajectoryis the uncertainty of its positioning. READ MORE

5. 19. A Game-theoretical Framework for Byzantine-Robust Federated Learning

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Wanyun Xie; [2022]
   Keywords : Game theory; distributed robust learning; training-time attacks; exploration-exploitation tradeoff; Spelteori; distribuerad robust inlärning; attacker på träningstiden; kompromiss mellan utforskning och exploatering;

   Abstract : The distributed nature of Federated Learning (FL) creates security-related vulnerabilities including training-time attacks. Recently, it has been shown that well-known Byzantine-resilient aggregation schemes are indeed vulnerable to an informed adversary who has access to the aggregation scheme and updates sent by clients.

6. 20. Frequency Stability of Power Electronic Based Power System with 100% Renewable Energy.

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Abdullah Albalali; [2022]
   Keywords : energy storage; frequency control; synchronous generators; distributed power generation; virtual synchronous machine VSM ; PSCAD.; energilagringssystem; frekvenskontroll; synkrona generatorer; distribuerad kraftproduktion; virtuell synkron maskin; PSCAD.;

   Abstract : The modern power system is aiming to progress away from conventional synchronous machine  based power generation towards converter dominated system that leads to extensively high penetration of renewable energy such as wind and PV. This transition of modern power system toward converter based renewable energy comes with new challenges as the conventional synchronous generation is being replaced by converter based power system (CBPS).
