  1. 16. Model-Based Investigation of Machining Systems Characteristics Static and Dynamic Stability Analysis

    University dissertation from Stockholm : KTH

    Author : Andreas Archenti; KTH.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining systems; modelling; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The increasing demands for precision and efficiency in machining call for new control strategies for machining systems based on the identification of static and dynamic characteristics under operational conditions. By considering the machining system as a closed-loop system consisting of a machine tool structure and a machining process, the join system characteristics can be analyzed. READ MORE

  2. 17. Computational Biomechanics in Cross-country Skiing

    University dissertation from Institutionen för ekonomisk och industriell utveckling

    Author : Joakim L. Holmberg; Linköpings universitet.; Linköpings universitet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer simulation; Inverse dynamics; Musculoskeletal; Optimization; Simulation model; Sports; Computational Biomechanics; Cross‐country Skiing; TECHNOLOGY Engineering mechanics; TEKNIKVETENSKAP Teknisk mekanik;

    Abstract : Traditionally, research on cross‐country skiing biomechanics is based mainly on experimental testing alone. Trying a different approach, this thesis explores the possibilities of using computational musculoskeletal biomechanics for cross‐country skiing. As far as the author knows, this has not been done before. READ MORE

  3. 18. Inverse Identification of Dynamic Wheel-rail Contact Forces

    University dissertation from Institutionen för ekonomisk och industriell utveckling

    Author : Hamed Ronasi; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inverse problems; sensitivity; optimization; regularization; railway mechanics; input estimation; load identification;

    Abstract : Accurate evaluation of contact forces between wheel and rail is essential in the assessmentof vehicle performance and to predict consequences of dynamic vehicle-track interaction.As the contact forces can not be measured directly in the field, one common approachis to measure the strain or acceleration at various positions on a wheel or wheel axle.

    Abstract : Aircraft engine manufacturers strive to improve current state of the art designs through continuous development efforts. By improving existing designs and exploring new alternatives, the goal is to reduce the fuel consumption - a topic of high relevance due to the remarkable growth rate of air traffc. READ MORE

  5. 20. Regional Energy Systems with Retrofitted Combined Heat and Power (CHP) Plants

    University dissertation from Västerås : Mälardalen University

    Author : Song Han; Mälardalens högskola.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combined heat and power; Waste-to-Energy WtE ; Regional energy system; Greenhouse gases GHG ; Retrofitting; Optimization; Kraftvärme; Avfall-till-Energi; Regionala Energisystem; Växthusgaser; Uppgradering; Optimering.; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Fossil fuel depletion, economic development, urban expansion and climate change present tough challenges to municipal- and regional-scale energy systems. Regional energy system planning, including waste treatment, renewable energy supply, energy efficiency, and climate change, are considered essential to meet these challenges and move toward a sustainable society.
