    Sammanfattning : A ship to which vehicles and other loads can be rolled on and off is usually named ro-ro ship. A ro-ro ship consists of large corridor shaped space, normally extending to a considerable length or the entire length of the ship, which is usually loaded with various vehicles or stowage units.

  3. 3. Thermal Exposure Caused by the Smoke Gas Layer in Pre-flashover Fires : A Two-zone Model Approach

    M1-uppsats, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Lucas Andersson; [2016]
    Nyckelord :Thermal exposure; smoke gas layer; two-zone model;

    Sammanfattning : A pre-flashover fire is very different from a post-flashover fire. The main difference is that in a pre-flashover fire the gas temperature and the radiation temperature differ. One thing that makes it a lot different is that the thermal exposure induced by a pre-flashover fire is largely affected by the smoke gas layer. LÄS MER

  4. 4. Influence of Building Structure and Building Content on Residential Fires

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Hilco Hiemstra; [2016]
    Nyckelord :Residential fires; Building structure; Building content; Insulation; Technology and Engineering;

    Sammanfattning : In Europe, there are still a significant amount of residential fires. Particularly fires in the living room are a major threat to the occupants. Much research has been done to residential fires. LÄS MER

  5. 5. Modeling of NOx formation in heavy duty engines

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Kenan Muric; [2011]
    Nyckelord :Technology and Engineering;

    Sammanfattning : In order to apply combustion feedback control in diesel engines to control pollution formation, good models are needed to estimate the states. One of those would be NOx levels which are regulated by European law. There are conventional sensors on the market that can measure NOx but these are too slow for in-cycle feedback control. LÄS MER
