2. 1. Fuel-Efficient Look-Ahead Control for Heavy-Duty Vehicles with Varying Velocity Demands

   Author : Manne Held; Jonas Mårtensson; Oscar Flärdh; Ardalan Vahidi; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; look-ahead control; optimal control; powertrain control; advanced driver assistance systems; Electrical Engineering; Elektro- och systemteknik;

   Abstract : The fuel consumption of heavy-duty vehicles can be reduced by using information about the upcoming road section when controlling the vehicles. Most manufacturers of heavy-duty vehicles today offer such look-ahead controllers for highway driving, where the information consists of the road grade and the velocity only has small variations.

4. 2. Wireless Control of Modular Multilevel Converter Submodules

   Author : Baris Ciftci; Hans-Peter Nee; Lennart Harnefors; Staffan Norrga; James Gross; Lars Kildehöj Rasmussen; Remus Teodorescu; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 5G mobile communication; autonomous control; converter control; distributed control; electromagnetic interference; emerging technology; fault ride-through; modular multilevel converter MMC ; prototype; wireless control; Electrical Engineering; Elektro- och systemteknik;

   Abstract : The modular multilevel converter (MMC) has extensively been used in high-voltage, high-power applications such as high-voltage dc transmission systems and flexible alternating current transmission systems. The control of MMC submodules is conventionally realized using wired communication systems. READ MORE

5. 3. Pedestal structure and stability in JET-ILW and comparison with JET-C

   Author : Estera Stefanikova; Lorenzo Frassinetti; Per Brunsell; Joelle Mailloux; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; JET; Thomson scattering; pedestal; pedestal position; pedestal stability; Europed modelling; Physics; Fysik;

   Abstract : Controlled thermonuclear fusion offers a promising concept for safe and sustainable production of electrical energy. However, there are still many issues to be investigated on the way to a commercial fusion reactor. An important point for detailed studies is connected to wall materials surrounding hot thermonuclear plasma. READ MORE

6. 4. Decarbonising the Stainless Steelmaking through Alloy Solutions

   Author : Wenjing Wei; Pär Jönsson; Peter Samuelsson; Birat Jean Pierre; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; optimization; raw material; process; quality; decarbonisation; rostfritt stål; optimering; material; process; kvalitet; avkarbonisering; Materials Science and Engineering; Teknisk materialvetenskap;

   Abstract : To reach the goal of the Paris Agreement, the reduction of greenhouse gas emissions (GHG)is becoming one of the most pressing issues in the world today. Unlike most other sectors, thestainless steel industry has a significantly higher burden from upstream emissions comparedto operational emissions. READ MORE

7. 5. Data-driven Production Logistics : A value-oriented transition approach

   Author : Masoud Zafarzadeh; Magnus Wiktorsson; Jannicke Baalsrud Hauge; Martin Rudberg; KTH; []
