  2. 1. Improved road design for future maintenance : analysis of road barrier repair costs

    Author : Hawzheen Karim; Ulf Isacsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; highway maintenance; highway management; highway design; road planning; road design; highway engineering; road barrier; cable barrier; w-beam barrier; road barrier damages; barrier repair cost.; Building engineering; Byggnadsteknik; Vägprojektering för minskade drift- och underhållskostnader;

    Abstract : The cost of a road construction over its service life is a function of the design, quality of construction, maintenance strategies and maintenance operations. Unfortunately, designers often neglect a very important aspect which is the possibility to perform future maintenance activities. READ MORE

  4. 2. Supporting the design phase of industrialised house building using a product platform approach : A case study of a timber based post and beam building system

    Author : Shamnath Thajudeen; Fredrik Elgh; Martin Lennartsson; Marcus Sandberg; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrialised house building; Product platform; Design support; Building system; Post and beam; Glulam; Industriellt husbyggande; Produktplattformar; Designstöd; Byggsystem; Pelar-balksystem; Limträ;

    Abstract : In recent years, industrialised house building has gained shares on the Swedish house building market. The market demands for industrialised house building are exceeding the available supply of housing and experiencing a substantial increase in the housing production costs. READ MORE

  5. 3. Addressing the complexity of sustainability-driven structural design: Computational design, optimization, and decision making

    Author : Alexandre Mathern; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; integrated design; concrete structure; parametric design; structural engineering; finite element analysis; life cycle sustainability assessment; bridge; construction; civil engineering; multi-objective design optimization; wind turbine foundation;

    Abstract : Being one of the sectors with the largest environmental burden and high socio-economic impacts sets high requirements on the construction industry. At the same time, this provides the sector with great opportunities to contribute to the globally pursued sustainability transition. READ MORE

  6. 4. Design and Performance of Optically Pumped Semiconductor Disk Lasers with Wide Tuning Ranges

    Author : Carl Borgentun; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optically pumped semiconductor disk laser; tuning range; high power; Semiconductor laser; vertical-external-cavity surface-emitting laser; design; beam characterization;

    Abstract : In this work I present a strategy for providing the possibility to select the wavelength, or color, of a semiconductor laser over a very large range, by cleverly designing the vital part of the laser: the gain element of a so called optically pumped semiconductor disk laser. Optically pumped semiconductor disk lasers (OP-SDLs) are a relatively new class of lasers showing great promise for future applications. READ MORE
