1. 21. New Tides in Shipping : Studying incumbent firms in maritime energy transitions

   Författare :Ignė Stalmokaitė; Björn Hassler; Johanna Yliskylä-Peuralahti; Tommy Larsson Segerlind; René Taudal Poulsen; Södertörns högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; shipping; incumbent firms; maritime energy transitions; multi-level perspective; dynamic capabilities; regime-niche interactions; decarbonisation; air-borne emissions; sustainability transitions; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

   Sammanfattning : Shipping is a cornerstone of global transportation responsible for moving large volumes of traded goods. At the same time, negative environmental impacts of shipping operations have attracted growing concerns. LÄS MER

3. 22. Modelling and Lagrangian control of mixed traffic: platoon coordination, congestion dissipation and state reconstruction

   Författare :Mladen Čičić; Karl Henrik Johansson; Miroslav Krstić; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; traffic control; Lagrangian control; mixed traffic models; Intelligent Transportation Systems; Connected and Automated Vehicles; traffic congestion; platoon coordination; moving bottlenecks; bottleneck decongestion; stop-and-go wave dissipation; traffic state reconstruction; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Traffic congestion is a constantly growing problem, with a wide array of negative effects on the society, from wasted time and productivity to elevated air pollution and reduction of safety. The introduction of connected, autonomous vehicles enables a new, Lagrangian paradigm for sensing andcontrolling the traffic, by directly using connected vehicles inside the traffic flow, as opposed to the classical, Eulerian paradigm, which relies on stationary equipment on the road.

4. 23. Towards sustainable heavy-duty transportation : Combustion and emissions using renewable fuels in a compression ignition engine

   Författare :Maja Novakovic; Förbränningsmotorer; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RME; HVO; E85; methanol; ethanol; decarbonization; defossilization; heavy-duty; compression-ignition engine; ow temperature combustion; PPC; emissions; PM; particles; aerosol; OA; SOA; DOC;

   Sammanfattning : Transportation should become sustainable and available to everyone. Currently, transportation accounts for approx. one sixth of greenhouse gas (GHG) emissions globally, and heavy-duty trucks are responsible for almost 30% of that. LÄS MER

5. 24. Multimodal Transportation under the Rotterdam Rules: Legal Implications for European Carriage of Goods and the Quest for Uniformity

   Författare :Olena Bokareva; Juridiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : A constantly growing intercontinental trade and modernization of transport infrastructure transformed the traditional patterns of carriage of goods globally. The majority of manufactured goods nowadays are transported in by sea in containers; however, transportation by land precedes and follows the sea carriage. LÄS MER

7. 25. The Internalization of External Effects in Swedish Transport Policy - A Comparison Between Road and Rail Traffic

   Författare :Lars Hansson; Internationella miljöinstitutet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Commercial and industrial economics; rail traffic; road traffic; transport policy; internalization; External effects; pricing-relevant costs; Industriell ekonomi;

   Sammanfattning : Transport is a key factor for economic growth. It has enabled both the economic scale of production and an increase in competition. No one can question this role of transportation. There is, however, a back-side to the coin: the environmental challenge. LÄS MER
