  2. 1. Controlling the Roll Responses of Volume Carriers

    Author : Carl-Johan Söder; Anders Rosén; Jan De Kat; KTH; []
    Keywords : PCTC; parametric roll; roll response; roll damping; rudder control; aerodynamic roll damping; roll mitigation; racking; Ikeda’s method; CFD; model tests; Full-scale tests; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : Modern volume carriers such as container vessels, cruise ships and Pure Car and Truck Carriers (PCTC’s) have become more vulnerable to critical roll responses as built in margins have been traded against increased transport efficiency. The research presented in this doctoral thesis aims at enhancing the predictability and control of these critical roll responses. READ MORE

    Author : Carl-Johan Söder; Jakob Kuttenkeuler; Dominic Hudson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PCTC; parametric roll; roll response; roll damping; rudder control; roll mitigation; racking;

    Abstract : Modern Panamax Pure Car and Truck Carriers (PCTC) have become more vulnerable to critical roll responses as built in margins have been traded against increased transport efficiency. The research presented in this licentiate thesis aims at enhancing the predictability and control of these critical roll responses. READ MORE

  5. 3. The role of implementation science in healthcare improvement efforts : investigating three complex interventions

    Author : Anna Westerlund; Monica Nyström; Anneli Ivarsson; Rickard Garvare; Eva Eurenius; Johan Thor; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; healthcare improvement; knowledge-practice gap; implementation science; complex interventions; implementation strategy; change facilitation; case studies; folkhälsa; Public health; hälso- och sjukvårdsforskning; health services research;

    Abstract : For decades, scholars have found significant gaps between the knowledge available and the knowledge applied in healthcare. Many potential benefits of adequate knowledge based interventions are therefore never achieved. A considerable body of knowledge has evolved on how to promote a better uptake of evidence-based knowledge into routine use. READ MORE

  6. 4. Planning for Solar Buildings in Urban Environments

    Author : Jouri Kanters; Avdelningen för Energi och byggnadsdesign; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; architecture; design tool; design process; solar energy; urban planning; photovoltaics; solar thermal; building integration; density; net zero energy buildings; interviews; parametric studies; action research;

    Abstract : Energy use in buildings accounts for a significant proportion of the total energy use in many countries. While past and current buildings have solely been energy consumers, future buildings will, besides using less energy, also need to produce (part of ) the required energy on site with renewables.

  7. 5. Development, Implementation, Validation and Applications of a Method for Simulation of Damaged and Intact Ships in Waves

    Author : Martin Schreuder; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The safety of ships at sea is a key aspect of shipping. Tragic passenger vessel accidents during the years motivates that large effort is spent on understanding the mechanisms of survivability of damaged ships. READ MORE
