  1. 1. Diagnosis in evolvable production systems

    Författare :Luis Ribeiro; José António Barata de Oliveira; Svetan Marin Ratchev; Carlos Eduardo Pereira; Portugal Universidade Nova de Lisboa Faculdade de Ciências e Tecnologia; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Esta tese aborda a problem�tica da execu��o de diagn�stico em instala��es industriais complexas que s�o compostas por um elevado n�mero de componentes que interagem entre si no �mbito do processo de produ��o.Apesar da abordagem apresentada ao problema ser geral e aplic�vel a v�rias classes de sistemas ligados em rede, o dom�nio dos Sistemas Evolutivos de Produ��o e os Sistemas Evolutions de Assembly (EPS/EAS) � utilizado como a base sobre a qual o sistema de diagn�stico proposto � implementado.

  2. 2. Marine Current Resource Assessment : Measurements and Characterization

    Författare :Nicole Carpman; Karin Thomas; Mats Leijon; Sandra Eriksson; Mairead Atcheson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ADCP; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : The increasing interest in converting energy from renewable resources into electricity has led to an increase in research covering the field of marine current energy, mainly concerning tidal currents and in-stream tidal turbines. Tides have the advantage of being predictable decades ahead. LÄS MER

  3. 3. Waste heat recovery in a cruise vessel

    Författare :Fredrik Ahlgren; Marcus Thern; Aykut Ölcer; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; whr; orc; ships; waste heat recovery; energy efficiency; cruise ships; Sjöfartsvetenskap; Maritime Science;

    Sammanfattning : In three studies of a cruise ship the author has investigated waste heat recovery (WHR)from exhaust gases using an organic Rankine cycle (ORC), and also mapped the energyand exergy flows within the ship. Data were collected from the ship’s machinerysystem for a total extent of one year, and this data were used for simulations andenergy calculations. LÄS MER

  4. 4. The Character of the Particle Emissions from Possible Future Marine Fuels in SOx ECAs

    Författare :Maria Anderson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heavy fuel oil; emission factor; marine fuel; black carbon; marine diesel oil; LNG; ship emission; liquefied natural gas; nanoparticle;

    Sammanfattning : Particles in the ambient air come from both natural and anthropogenic sources. One anthropogenic source is combustion of fossil fuels. The awareness of these particles impact on human health and climate has increased the interest for the particle emissions from e.g. LÄS MER

  5. 5. Environmental assessment of present and future marine fuels

    Författare :Selma Brynolf; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Our globalised world is connected by shipping, an industry powered by one of heaviest and dirtiest products of refining: heavy fuel oil. Tougher environmental regulations are now challenging the industry to take action. LÄS MER
