  1. 1. Applying Design Analytics to Understand Engineering Change Request Information

    Författare :Ívar Örn Arnarsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Design Structure Matrix; Design Analytics; Engineering Change Request; Markov chain.; Product Development;

    Sammanfattning : Large complex system development projects take several years to carry out. Such projects involve hundreds of engineers who develop tens of thousands of parts and millions of lines of code. During the course of a project, many design decisions often need to be changed due to the emergence of new information. LÄS MER

  3. 2. Methanation of biosyngas in a fluidized bed reactor

    Författare :Martin Seemann; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENERGY TECHNOLOGY; REGENERATIVE ENERGIES; GASIFICATION OF WOOD; FLUIDIZED BED PROCESSES; CHEMICAL ENGINEERING; FUEL TECHNOLOGY; ALTERNATIVE ENERGIES; METHANATION OF HYDROGEN-CARBONMONOXIDE MIXTURES; SYNTHETIC FUELS; NATURAL GAS; BIOGASES;

    Sammanfattning : Rising prices for fossil fuels and concerns over the climate change increase the interest in renewable energies. Synthetic natural gas (SNG) can be an option, filling the request for alternatives in the transportation sector, where the dependence on the oil is very strong. LÄS MER

  4. 3. Systematic Analysis of Engineering Change Request Data - Applying Data Mining Tools to Gain New Fact-Based Insights

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Markov chain; Machine learning.; Product Development; Design Structure Matrix; Design Analytics; Engineering Change Request;

    Sammanfattning : Large, complex system development projects take several years to execute. Such projects involve hundreds of engineers who develop thousands of parts and millions of lines of code. During the course of a project, many design decisions often need to be changed due to the emergence of new information. LÄS MER

  5. 4. Interpretation of Railway Track Alignment Measurements in a Geodynamic Perspective

    Författare :Jonas Majala; Jan Laue; Thorkild Maack Rasmussen; Kenneth Viking; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic load; Railway; Frequency; Track measurement; Geoteknik; Soil Mechanics;

    Sammanfattning : The development in society means that infrastructure like ballasted railway systems are facing challenges due to request for increased number of high-speed trains and heavier freight trains. This implies that ballasted railways get an increased impact from larger dynamic loads. LÄS MER

  7. 5. Filtrerad Effektivitet

    Författare :Sten Setterberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Slack; Organization; Performance filter; Knowledge absorption; Efficiency; Capability;

    Sammanfattning : AbstractThere are at least three different aspects influencing the understanding and the ability for a development organization to develop the products demanded in the product strategy of a company. Firstly the strategy has to be communicated enabling the organization to understand the request. LÄS MER
