  1. 1. Differential railway track settlement in a transition zone – Field measurements and numerical simulations

    Författare :Kourosh Nasrollahi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fibre Bragg grating sensors; dynamic vehicle–track interaction; heavy haul traffic; non-linear track model; 3MB slab track; Transition zone; empirical settlement model; condition monitoring;

    Sammanfattning : In a transition zone between two different railway track forms, there is a discontinuity in track structure leading to a gradient in track stiffness. Examples include transitions between different superstructures, e.g., slab track to ballasted track, and/or between different substructures, e. LÄS MER

  3. 2. Distributed engineering : tools and methods for collaborative product development

    Författare :Peter Törlind; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design; Funktionella produkter; Functional Product Development;

    Sammanfattning : Engineering design is fundamentally social, requiring much interaction and communication between the people involved. Additionally, good design often relies upon the ability of a cross-functional team to create a shared understanding of the task, the process, and the respective roles of its members. LÄS MER

  4. 3. Introducing Continuous Experimentation on Resource-Constrained Cyber-Physical Systems

    Författare :Federico Giaimo; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cyber-Physical Systems; Continuous Experimentation; Software Engineering;

    Sammanfattning : Software is ubiquitous and shapes our world, but at the same time it can be viewed as a plastic resource offering the possibility to be improved even after its deployment to better serve its purpose. Exploiting this possibility, the Continuous Experimentation practice is gaining momentum on connected software-intensive web-based systems, allowing the product owners to deploy "experiments" on their software systems, i.

  5. 4. Quality Control of a Newsprint TMP Refining Process based on Refining Zone Temperature Measurements

    Författare :David Sikter; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temperature profile; quality control; usability; economy; TMP refining;

    Sammanfattning : The ultimate goal of this study was to examine the possibility of using temperature measurements for control purposes in a TMP refining process. The study was carried out in a commercial refiner line at Holmen Paper’s Hallsta Mill, were the primary stage refiner was equipped with temperature sensors. LÄS MER

  7. 5. Stainless Steel Corrugated Web Girders for Composite Road Bridges: Concept Evaluation and Flange Buckling Resistance

    Författare :Fatima Hlal; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Investment cost; Genetic algorithm; Duplex stainless steel; LCC; Corrugated web; Flange buckling resistance; Optimization; Composite bridges; LCA; Road bridges;

    Sammanfattning : Achieving a sustainable bridge design requires careful consideration of economic viability and environmental impact over the entire lifespan of the structure. While stainless steel is recognized for its excellent life cycle performance, its high cost prevents it from being used to a larger extent in bridges. LÄS MER
