2. 21. Engineering short-chain carboxylic-acid metabolism in the model microorganism Escherichia coli

   Author : Gustav Sjöberg; Antonius J. A. van Maris; Solange Mussatto; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metabolic engineering; R -3-hydroxybutyrate; volatile fatty acids; bioprocess design; Escherichia coli; bacterial artificial chromosome; Bioteknologi; Biotechnology;

   Abstract : The ever-increasing concern about carbon dioxide emissions has created an urgent need to develop alternative methods to cheaply and renewably produce materials, chemicals and fuels. The biorefinery is uniquely suited to deliver these products from sustainable biomass. READ MORE

4. 22. Analysis and engineering of central metabolism in Clostridium thermocellum

   Author : Teun Kuil; Antonius J. A. van Maris; Ruud Weusthuis; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Clostridium thermocellum; biofuels; ethanol; atypical glycolysis; pyrophosphate; phosphofructokinase; thermodynamic driving force; redox cofactor balancing; amino acid secretion; chaotropicity; hexose utilization; laboratory evolution; metabolic engineering; Biotechnology; Bioteknologi;

   Abstract : To mitigate climate change, greenhouse gas emissions must be reduced to net-zero in 2050 requiring a drastic transition in today´s energy sector. To achieve this goal, the use of biofuels produced from lignocellulosic feedstocks, including agricultural and forestry residues, is expected to play an important role. READ MORE

5. 23. Criteria for Machinability Evaluation of Compacted Graphite Iron Materials : Design and Production Planning Perspective on Cylinder Block Manufacturing

   Author : Anders Berglund; Cornel Mihai Nicolescu; Leonardo De Chiffre; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metal Cutting; Compacted Graphite Iron CGI ; Machinability; Design of Experiments DoE ; Inverse Finite Element FE Modelling; Simulated Milling Method; SRA - Produktion; SRA - Production;

   Abstract : The Swedish truck industry is looking for new material solutions to achieve lighter engines with increased strength to meet customer demands and to fulfil the new regulations for more environmentally friendly trucks. This could be achieved by increasing the peak pressure in the cylinders. READ MORE

6. 24. Information Management for Factory Planning and Design

   Author : Danfang Chen; Torsten Kjellberg; Terje Kristoffer Lien; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SRA - Production; SRA - Produktion;

   Abstract : This thesis is dedicated to the manufacturing industry for the improvement of information management within the factory planningand design domain, and for more efficient factory planning and design. Currently the manufacturing industry lacks sufficient methods for capturing, structuring, and representing information and knowledge for easy access, exchange, integration and reuse within the domain.

7. 25. An Analysis of the Proactive Approach as a Potential Tool for Adaptability in Production Systems

   Author : Kerstin Dencker; Mauro Onori; Lena Mårtensson; Monica Bellgran; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Assembly; production system design; proactivity; human-machine collaboration; SRA - Production; SRA - Produktion;

   Abstract : Competitive systems for manufacturing, especially assembly systems, have to cope with frequent changes of external as well as internal demands. A proactive behaviour in an assembly system should make it capable of rapid changes and have an ability to handle frequent changes and disturbances. READ MORE
