  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

  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.
