  2. 2. A Techno-Economic Framework for the Analysis of Concentrating Solar Power Plants with Storage

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Rafael Guédez; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concentrating solar power; thermal energy storage; techno-economic analysis; Termisk solkraft; termisk energilagring; techno-eknomiska analys; Energiteknik; Energy Technology;

    Abstract : Concentrating solar power plants can integrate cost-effective thermal energy storage systems and thereby supply controllable power on demand, an advantage against other renewable technologies. Storage integration allows a solar thermal power plant to increase its load factor and to shift production to periods of peak demand. READ MORE

  3. 3. Integrated Life Cycle Design - Applied to concrete multi-dwelling buildings

    University dissertation from Division of Building Materials, LTH, Lund University

    Author : Mats Öberg; Lunds universitet.; Lund University.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; livslängd; materialval; energianvändning; inomhusklimat; livscykelanalyser; livscykelkostnader; hållbar utveckling; Sustainable construction; Building construction; Service life design; Multiple Attribute Decision Analysis; Energy efficient buildings; Life Cycle Assessment; projektering; betongkonstruktioner; flerbostadshus; Byggnadsteknik; Integrated life cycle design; Life Cycle Costing;

    Abstract : Popular Abstract in Swedish Syftet med arbetet är att undersöka och påvisa hur ett bostadshus kan projekteras så att funktionen på bästa sätt motsvarar de krav som ställs, till lägsta möjliga kostnad och miljöpåverkan över hela livscykeln. Såväl metodiken för helhetsprojektering, som byggnadens specifika egenskaper och funktioner studeras. READ MORE

  4. 4. A Material Framework for Product Design

    University dissertation from Faculty of Engineering and Department of Design Sciences, Lund University

    Author : Charlotte Asbjørn Sörensen; Malmö University.; Malmö University.; [2018]
    Keywords : INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN; Technology; experiential learning; material practices in design; pedagogic framework; higher education; product design; material selection; sensorial characteristics; technical properties; material criteria activities; case study;

    Abstract : A new paradigm is slowly making its way into society, affecting our material practice as designers. Materials selection in design and product development has for a long time been dominated by a purely technical approach, mainly focusing on properties and performance. READ MORE

  5. 5. Quasi-analytical Modelling and Optimisation Techniques for Transport Aircraft Design

    University dissertation from Institutionen för flygteknik

    Author : Askin T. Isikveren; KTH.; [2002]
    Keywords : aircraft; conceptual; design; specifications; atmosphere; geometry; weight; aerodyanmics; propulsion; operational performance; stability and control; constrained multi-objective optimisation; computer aided design; regional; business; high-transonic; ;

    Abstract : The research work presented here focuses on the subject oftransport aircraft design at the pre-design or conceptuallevel. The primary topics addressed are: (1) generation of avast array of new quasi-analytical expressions to permit aconceptual treatment of commercial and business transportaircraft with adequate sensitivity for more advanced tradestudies; (2) review and adoption of a method to predictstability and control characteristics (using the Mitchellmethod); (3) a study of the relative merits between variousmethods in facilitating an expedient and robust constrainedmulti-objective optimisation result within the context oftraditional conceptual design problems (Genetic Algorithms andNelder-Mead Simplex search); (4) creation of a software packageas a new and unique conceptual tool that permits the generationof design proposals in an accurate yet expeditious manner; and,(5) practical demonstration of the new conceptual designsoftware package by undertaking some actual aircraft designproposals.
