1. 21. Multidimensional engineering for the production of fatty acid derivatives in Saccharomyces cerevisiae

   Författare :Yating Hu; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein engineering; Saccharomyces cerevisiae; fatty acid derivatives; metabolic engineering; tolerance; transporter;

   Sammanfattning : Saccharomyces cerevisiae , also known as budding yeast, has been important for human society since ancient time due to its use during bread making and beer brewing, but it has also made important contribution to scientific studies as model eukaryote. The ease of genetic modification and the robustness and tolerance towards harsh conditions have established yeast as one of the most popular chassis in industrial-scale production of various compounds.

3. 22. Optimal Design of District Energy Systems: a Multi-Objective Approach

   Författare :Cong Wang; Ivo Martinac; Birgit Müller; KTH; []
   Nyckelord :HUMANIORA; HUMANITIES; multi-objective optimization; robust design optimization; district energy; Civil and Architectural Engineering; Byggvetenskap;

   Sammanfattning : The aim of this thesis is to develop a holistic approach to the optimal design of energy systems for building clusters or districts. The emerging Albano university campus, which is planned to be a vivid example of sustainable urban development, is used as a case study through collaboration with the property owners, Akademiska Hus and Svenska Bostäder.

4. 23. Product support and spare parts considering system reliability and operating environment

   Författare :Behzad Ghodrati; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

   Sammanfattning : The required spare parts planning for a system/machine is an integral part of the product support strategy. The number of required spare parts can be effectively estimated on the basis of the product reliability characteristics. LÄS MER

5. 24. A Critical Review of the Observational Method

   Författare :Johan Spross; Stefan Larsson; Fredrik Johansson; Joakim Jeppsson; Lars Rosén; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock mechanics; observational method; Eurocode 7; reliability analysis; dam safety; tunnelling; system reliability; Byggvetenskap; Civil and Architectural Engineering;

   Sammanfattning : Building a sustainable structure in soil or rock that satisfies all predefined technical requirements implies choosing a rational and effective construction method. An important aspect is how the performance of the structure is verified. LÄS MER

7. 25. Computational Methods in Conceptual Structural Design

   Författare :Vedad Alic; Byggnadsmekanik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conceptual design; conceptual structural design; ground-borne vibrations; form finding; optimization; dynamic relaxation; graphic statics; reciprocal figures; strut-and-tie; finite element method; isogeometric analysis; NURBS; CAD; numerical modelling;

   Sammanfattning : Conceptual design is the first phase in the design process in which all the requirements and design objectives are synthesized into conceptual alternatives. In practice today, major decisions regarding the buildings function, massing, and overall form are usually made during the first phase. LÄS MER
