1. 1. Controlling the Roll Responses of Volume Carriers

   Författare :Carl-Johan Söder; Anders Rosén; Jan De Kat; KTH; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

3. 2. Controlling the Roll Responses of PCTC's

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

   Sammanfattning : 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. LÄS MER

4. 3. District Heating and CHP : Local Possibilities for Global Climate Change Mitigation

   Författare :Kristina Difs; G. Björn Karlsson; Louise Trygg; Thomas B. Johansson; Linköpings universitet; []
   Nyckelord :District heating; combined heat and power; carbon dioxide emissions; optimisation; energy policies; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Global warming, in combination with increasing energy demand and higher energy prices, makes it necessary to change the energy use. To secure the energy supply and to develop sustainable societies, construction of energy-efficient systems is at the same time most vital. LÄS MER

5. 4. Approaching transformative futures : Discourse and practice in Swedish national transport policy and planning

   Författare :Jacob Witzell; Karolina Isaksson; Maria Håkansson; Malin Henriksson; Raine Mäntysalo; KTH; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; transport planning; transport infrastructure; climate mitigation; transformation; planning practice; uncertainty; assessment; Urbana och regionala studier; Urban and Regional Studies;

   Sammanfattning : This thesis concerns the need to transform the transport system to meet climate mitigation objectives. It provides insights into how specific approaches and practices in transport policy and planning affect prospects for transformation. LÄS MER

7. 5. Adding Fuel to the Fire : North-South dynamics in the geographies of transport energy: the case of EU biofuels

   Författare :David Harnesk; LUCSUS; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; energy geography; geopolitics; territorialisation; climate change mitigation; transport; biofuels; agrofuels; European Union EU ; certification; sustainability criteria; sustainability science; energi; geografi; geopolitik; territorialisering; klimatomställning; transport; biodrivmedel; biobränsle; Europeiska Unionen; certifiering; hållbarhetskriterier; hållbarhetsvetenskap;

   Sammanfattning : Since the 2000s, the European Union (EU) has promoted biofuels for transport to achieve climate change mitigation, and rural development in the global South. In contrast, critiques have argued that biofuel promotion impedes more meaningful mitigation while also resulting in dispossession of land and loss of labour opportunities in the global South. LÄS MER
