  1. 1. Static and fatigue analyses of welded steel structures some aspects towards lightweight design

    University dissertation from Stockholm : KTH School of engineering sciences

    Author : Mansoor Khurshid; KTH.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue strength; welded joints; static strength; high strength steel; Farkostteknik; Vehicle and Maritime Engineering; Aerospace Engineering; Flyg- och rymdteknik;

    Abstract : The objectives of this thesis comprise of overcoming the challenges in designing lightweight welded structures such as material selection, choice of fatigue design methods, and increased performance by using improvement techniques. Material selection of welded joints is dependent on the filler and base material strengths. READ MORE

  2. 2. Risk-based ship security analysis – an approach based on civilian and military methods

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Hans Liwång; Försvarshögskolan.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Försvarssystem; Military Technology; naval ship; piracy; risk-based; risk control options; ship security analysis;

    Abstract : The demands on maritime operations today are increasingly higher in terms of control, efficiency and cost. The margins for accidents and security incidents are therefore decreasing. In the area of ship safety the regulations, guidelines and methods have a history and culture of systematic research, development and implementation. READ MORE

  3. 3. Sound propagation from sustainable ground vehicles from aeroacoustic sources to urban noise

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Nicolas Pignier; KTH.; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sound propagation; sound generation; ground vehicle; aeroacoustics; aerodynamics; Kirchhoff approximation; detached eddy simulation; Ffowcs Williams and Hawkings; ljudutberdning; ljudalstring; markfordon; aeroakustik; aerodynamik; Kirchhoff approximation; detached eddy simulation; Ffowcs Williams and Hawkings; Farkostteknik; Vehicle and Maritime Engineering; Teknisk mekanik; Engineering Mechanics;

    Abstract : Transportation is the main source of environmental noise in Europe, with an estimated 125 million people affected by excessive noise levels from road traffic, causing a burden of noise related diseases and having a substantial economic impact on society. In order to reduce exposure to high levels of traffic noise, two approaches are the topic of extensive research: preventing sound from propagating from roads and railways using for example noise barriers, and reducing the sources of noise themselves.

  4. 4. Technical cost modelling and efficient design of lightweight composites in structural applications

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Mathilda Karlsson Hagnell; KTH.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technical cost modelling; composite materials; carbon fibre; lightweight design; optimization; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : A lightweight transport design reduces fuel costs and emissions and can be achieved through the use of fibre-reinforced composite materials. Although lightweight, the composite raw material can be expensive and the sequential component production challenging and costly. READ MORE

  5. 5. NOx Abatement Technique for Marine Diesel Engines - Improved Marine SCR Systems

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Abstract : Growing awareness of the environmental implications of nitrogen oxide (NOX) emissions, such as eutrophication and acidification on land and at sea, has contributed to the development of more stringent international NOX legislations within the framework of the International Maritime Organization (IMO). The most stringent IMO legislation, i.e. READ MORE
