2. 1. Satistical Modelling Of CO2 Exchange Between Land And Atmosphere : Using Stochastic Optimisation And Gaussian Markov Random Fields

   Author : Unn Dahlén; Spatio-Temporal Stochastic Modelling Group; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gaussiska Markovfält; Stokastisk optimering; CO2-flöden; Spatial statistik; Stochastic Optimisation; Gaussian Markov Random Fields; Atmospheric inverse modelling; Spatial statistics; Computational statistics;

   Abstract : This thesis focuses on the development and application of efficient mathematicaltools for estimating and modelling the exchange of carbon dioxide (CO2) between the Earth and its atmosphere; here referred to as the global CO2 surface flux.There are two main approaches for estimating the CO2 flux: Processed based(bottom-up) modelling and atmospheric inversion (top-down) modelling.

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

   Author : Hamza Bouchouireb; Ciarán J. O'Reilly; Peter Göransson; Rupert J. Baumgartner; José Potting; Mario Hirz; KTH; []
   Keywords : 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;

   Abstract : 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.

7. 5. Manufacturing management and decision support using simulation-based multi-objective optimisation

   Author : Leif Pehrsson; David Stockton; Ng Amos; Mats Jackson; Raouf Hamzaoui; Högskolan i Skövde; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Management; Decision Support; simulation; Multi-objective; optimisation; Production systems; Teknik; Technology;

   Abstract : A majority of the established automotive manufacturers are under severe competitive pressure and their long term economic sustainability is threatened. In particular the transformation towards more CO2-efficient energy sources is a huge financial burden for an already investment capital intensive industry. READ MORE
