11. Born in fire, borne by air : Source attribution and physicochemical characterization of ship and ambient aerosols in the Baltic region
Sammanfattning : Aerosol emissions from anthropogenic activities cause detrimental health effects and affect the climate system. Combustion is a large source of airborne fine particulate matter (PM2.5) and the uncertainties of the climate role of these emissions are still large. LÄS MER
12. Simulation model of a ship’s energy performance and transportation costs
Sammanfattning : Society faces a major challenge to reduce greenhouse gas emissions to limit the effects and propagation of climate change. As the main contributor to global trade, the shipping industry adds significantly to global greenhouse gas emissions and must actively work towards reducing, or eliminating, emissions in a short period.

13. Navigating towards environmental impact assessment of shipping
Sammanfattning : The shipping sector exert multiple pressures on the environment, affecting climate change, human health and the marine environment. From a policy perspective, shipping is usually assessed based on the emissions to air (e.g. LÄS MER
14. Modeling and Control of EGR on Marine Two-Stroke Diesel Engines
Sammanfattning : The international marine shipping industry is responsible for the transport of around 90% of the total world trade. Low-speed two-stroke diesel engines usually propel the largest trading ships. This engine type choice is mainly motivated by its high fuel efficiency and the capacity to burn cheap low-quality fuels.

15. Efficient hull design for ice conditions in inland waterways
Sammanfattning : With increasing interest in utilizing the inland waterways (IWW) in European countries, the design of IWW vessels gains attention both from a transport efficiency and an emission control point of view. Usually, IWW ships are designed without ice operation concerns and are structurally weaker than ships designed according to ice-class notifications from the classification societies. LÄS MER
