1. 31. Electricity Market Design Strategies for Hydro-dominated Power Systems : Exploring Optimal Bidding, Planning, and Strategic Operation through Various Market Design Strategies

   Författare :Abolfazl Khodadadi; Lennart Söder; Audun Botterud; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nordic Balancing Model; Electricity Market Designs; Stochastic Optimization; Contract-for-Difference Contracts; Nordiska Balanseringsmodellen; Design av Elektricitetsmarknader; Stokastisk Optimering; Kontrakt- för-Skillnad Kontrakt; Electrical Engineering; Elektro- och systemteknik; Nationalekonomi; Economics;

   Sammanfattning : The existing wholesale power markets in Nordic countries play a vital role in ensuring the planned balance between supply and demand. However, these markets do not guarantee real-time operational security of the power system. LÄS MER

3. 32. Multidisciplinary Design of Transonic Fans for Civil Aeroengines

   Författare :Oliver Sjögren; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design of experiment; Turbofan performance; Stochastic sensitivity analysis; Jet propulsion; Performance optimization; Multidisciplinary design; Transonic fan stage design;

   Sammanfattning : For current state-of-the-art turbofan engines the bypass section of the fan stage alone provides the majority of the total thrust in cruise and the size of the fan has a considerable effect on overall engine weight and nacelle drag. Thrust requirements in different parts of the flight envelope must also be satisfied together with sufficient margins towards stall. LÄS MER

4. 33. Life Cycle Energy Optimisation: A multidisciplinary engineering design optimisation framework for sustainable vehicle development

   Författare :Hamza Bouchouireb; Ciarán J. O'Reilly; Peter Göransson; Rupert J. Baumgartner; José Potting; Mario Hirz; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life cycle energy optimisation; Multidisciplinary optimisation; Integrative design; Sustainable vehicle design; Functional conflicts; Vehicle aerodynamics; Battery energy storage systems; Robust design; Uncertainty propagation; Livscykelenergi; Fordonsdesign; Optimering; Tvär-funktionella konflikter; Farkostteknik; Vehicle and Maritime Engineering;

   Sammanfattning : This thesis explores how the systemic-level environmental footprint of light-duty vehicles could be reduced through integrative design using the Life Cycle Energy Optimisation (LCEO) methodology. This methodology aims at finding a design solution that uses a minimum amount of cumulative energy demand over the different phases of the vehicle's life cycle; while complying with a set of functional constraints, thereby avoiding any sub-optimal energy demand shifts between the vehicle's different life cycle phases.

5. 34. Optimal Design of Neuro-Mechanical Networks

   Författare :Carl-Johan Thore; Anders Klarbring; Matts Karlsson; Petter Krus; Mathias Stolpe; Linköpings universitet; []
   Nyckelord :Neuro-mechanical networks; active structures; neural networks; structural optimization; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : This thesis concerns modeling and optimal design of Neuro-Mechanical Networks. A Neuro-Mechanical Network (NMN) can be described as an active mechanical structure, made up from a network of simple but multifunctional elements that interact with their nearest neighbors. LÄS MER

7. 35. Optimal Design of Neuro-Mechanical Networks

   Författare :Carl-Johan Thore; Anders Klarbring; Matts Karlsson; Petter Krus; Mathias Stolpe; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Many biological and artificial systems are made up from similar, relatively simple elements that interact directly with their nearest neighbors. Despite the simplicity of the individual building blocks, systems of this type, network systems, often display complex behavior — an observation which has inspired disciplines such as artificial neural networks and modular robotics.
