  1. 1. Sustainability-, Buildability- and Performance-driven Structural Design

    Author : Alexandre Mathern; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; sustainability; structural engineering; civil engineering; design method; finite element analysis; concrete structures; material developments; buildability; performance; structural developments; requirements; construction technology; integrated design; bridges; constructability;

    Abstract : The construction, maintenance and operation of infrastructure networks represent substantial impacts, both positive and negative, in all three dimensions of sustainability: economic, social and environmental. The greatest possibility to reduce the negative impacts and increase the positive ones is at the early design stage of construction projects. READ MORE

  2. 2. Human Centred Design for Maritime Safety: A User Perspective on the Benefits and Success Factors of User Participation in the Design of Ships and Ship Systems

    Author : Nicole Almeida Costa; Chalmers tekniska högskola; []
    Keywords : HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; domain knowledge; co-design; design decisions; participatory design; maritime safety.; sociotechnical systems; integration; participatory ergonomics; user centred design;

    Abstract : For over six decades, Human Centred Design (HCD) has been considered a desired design approach for the implementation of Human Factors/Ergonomics (HF/E) knowledge and methods for understanding the needs of the end-users. Although other comparable frameworks exist, they can be seen as subcategories or as tools for HCD, as HCD is considered by some as an overarching approach. READ MORE

  3. 3. Advancing the life cycle energy optimisation methodology

    Author : Hamza Bouchouireb; Ciarán J. O'Reilly; Peter Göransson; Rupert J. Baumgartner; José Potting; Tracy Bhamra; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; life cycle energy; vehicle design; optimisation; functional conflicts; livscykelenergi; fordonsdesign; optimering; tvär-funktionella konflikter; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : The Life Cycle Energy Optimisation (LCEO) methodology aims at finding a design solution that uses a minimum amount of cumulative energy demand over the different phases of the vehicle's life cycle, while complying with a set of functional constraints. This effectively balances trade-offs, and therewith avoids sub-optimal shifting between the energy demand for the cradle-to-production of materials, operation of the vehicle, and end-of-life phases.

  4. 4. Modelling the integration of Additive Manufacturing technologies in design for space components

    Author : Olivia Borgue; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model-based; space components; Additive Manufacturing; DfAM.; Technology integration;

    Abstract : Products for space applications are traditionally costly and produced in small batches. Moreover, they must be able to withstand extreme environments and meet tough requirements when in operation, as the ability to maintain and repair them is limited. READ MORE

  5. 5. Railway operation analysis : Evaluation of quality, infrastructure and timetable on single and double-track lines with analytical models and simulation

    Author : Olov Lindfeldt; Bo-Lennart Nelldal; Lars-Göran Mattsson; Ingo Hansen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway operation; Railway capacity; Single-track; Double-track; Partial double-track; Inter-station distance; Delay; Delay propagation; Crossing; Overtaking; Timetable flexibility; Simulation; Experimental design; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Abstract : This thesis shows the advantages of simple models for analysis of railway operation. It presents two tools for infrastructure and timetable planning. It shows how the infrastructure can be analysed through fictive line designs, how the timetable can be treated as a variable and how delays can be used as performance measures. READ MORE
