1. 16. 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

3. 17. A Comparative Study of Optimization Methods for a Resource Allocation in Mobile Communications

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Dexter Leander; [2022]
   Keywords : ;

   Abstract : This thesis addresses a resource allocation problem in mobilecommunications. The objective is to allocate a set of resource blocks to a set of users in a way that the total transmission rate between them is maximized. READ MORE

4. 18. Modeling the Head Effect in Hydropower River Systems using MILP and BLP Approaches

   University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

   Author : Lina Larsson; Mikaela Lindberg; [2022]
   Keywords : Hydropower optimization; Hydropower scheduling; The head effect; Bilinear programming; Mixed-integer linear programming;

   Abstract : With a fast-growing electricity demand and a larger proportion of intermittent energy sources follows a greater need for flexible and balancing sources of electricity, such as hydropower. Planning of hydropower production is considered to be a difficult problem to solve due to several nonlinearities, combinatorial properties and the fact that it is a large scale system with spatial-temporal coupling.

5. 19. Optimization of Infrastructure Investment for Decarbonization of Public Buses Through Electricity and Hydrogen : The Case Study of Umeå

   University essay from KTH/Energiteknik

   Author : Maria Inês Rocha Jacob; [2022]
   Keywords : Electric buses; fuel cell buses; renewable energy sources; green hydrogen; EV charging stations; hydrogen refuelling stations; Sweden; Elbussar; bränslecellsbussar; förnybara energikällor; grön vätgas; laddningsstationer för elfordon; tankstationer för vätgas; Sverige;

   Abstract : Battery electric vehicles and fuel cell vehicles, i.e. hydrogen vehicles, are promising alternatives to internal combustion engine vehicles to reduce GHG emissions from the transport sector. EV charging and hydrogen refuelling infrastructure is crucial to the deployment of alternative fuels in transport. READ MORE

6. 20. Benchmarking algorithms and methods for task assignment of autonomous vehicles at Volvo Autonomous Solutions

   University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

   Author : Jonas Berglund; Ida Gärling; [2022]
   Keywords : Autonomous Vehicles; Mixed Integer Linear Programming; Genetic Algorithm; Task Assignment; Multi-Robot Task Allocation;

   Abstract : For unmanned vehicles, autonomy means that the vehicle’s route can be planned and executed according to some pre-defined rules in the absence of human intervention. Autonomous vehicles (AVs) have become a common type of vehicle for various kinds of transport, for example autonomous forklifts within a warehouse environment. READ MORE
