2. 1. Feedback control of resistive wall modes in the reversed field pinch

   Author : Dimitry Yadikin; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Reversed eld pinch; current driven modes; thin resistive wall; resistive wall; Fysik; Physics; Fysik;

   Abstract : A wide range of unstable current driven MHD modes is present in the re- versed τeld pinch (RFP) conτguration. An ideally conducting wall facing the plasma can stabilize the ideal MHD modes. READ MORE

4. 2. Data Driven AI Assisted Green Network Design and Management

   Author : Meysam Masoudi; Cicek Cavdar; Jens Zander; Muhammad Ali Imran; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 6G; 5G; Energy efficiency; Machine learning; Reinforcement learning; Network architecture; Sleep modes; Mobile networks; 5G; C-RAN; nätverksarkitektur; nätverksdelning; maskininlärning;

   Abstract : The energy consumption of mobile networks is increasing due to an increase in traffic demands and the number of connected users to the network. To assure the sustainability of mobile networks, energy efficiency must be a key design pillar of the next generations of mobile networks. READ MORE

5. 3. Resistive Wall Mode Stability and Control in the Reversed Field Pinch

   Author : Dmitriy Yadikin; Per Brunsell; Mikhail Gryaznevich; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Resistive wall modes; RWM; active control; feedback; MHD modes; Reversed-Field pinch; RFP; intelligent shell; mode control; Electrophysics; Elektrofysik;

   Abstract : Control of MHD instabilities using a conducting wall together with external magnetic fields is an important route to improved performance and reliability in fusion devices. Active control of MHD modes is of interest for both the Advanced Tokamak and the Reversed Field Pinch (RFP) configurations. READ MORE

6. 4. Optimization Methods for Robust Control with Application to Resistive Wall Modes in Tokamaks

   Author : Carl-Magnus Fransson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; H?; fusion; QFT; performance; tokamak; optimization; robustness; structured singular value; control; plasma; resistive wall modes; LMI; PID control;

   Abstract : In many research areas physical systems are described by mathematical models. We focus here on systems that are regulated by a controller, typically realized by software, whose design involves certain parameters. READ MORE

7. 5. Data-driven predictive maintenance planning and scheduling

   Author : Mahdieh Sedghi; Bjarne Bergquist; Erik Vanhatalo; Ramin Karim; Luleå tekniska universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik och logistik; Quality Technology and Logistics;

   Abstract : The railway track network is one of the major modes of transportation and among a country’s most valuable infrastructure assets. Maintenance and renewal of railway infrastructure have a vital role in safety performance, the quality of the ride, train punctuality, and the life cycle cost of assets. READ MORE
