  1. 1. Quantifying human balance : Analysis of force plate data

    Författare :Annica Önell; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systems engineering; Systemteknik; Systemanalys; Systems Analysis;

    Sammanfattning : There is a lack of reliable methods for assessment of balance suited for routine use in clinical settings. The thesis focuses on analysis of force plate data for evaluation of balance during normal, unperturbed standing and sitting. Some commonly used force plate based methods during unperturbed standing are presented. LÄS MER

  3. 2. Block stability analysis using deterministic and probabilistic methods

    Författare :Mehdi Bagheri; Håkan Stille; Charlie C. Li; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Block stability analysis; Model uncertainty; Joint relaxation; Partial factor; Sensitivity analysis;

    Sammanfattning : This thesis presents a discussion of design tools for analysing block stability around a tunnel. First, it was determined that joint length and field stress have a significant influence on estimating block stability. LÄS MER

  4. 3. Vehicle Dynamics Control after Impacts in Multiple-Event Accidents

    Författare :Derong Yang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Accidents statistics show that multiple-event accidents (MEAs) represent a considerable and increasing proportion of all vehicle traffic accidents. MEAs are characterized by having at least one vehicle subjected to more than one harmful event. MEAs now comprise approximately 25% of all passenger vehicle accidents. LÄS MER

  5. 4. Computer Vision Based Analysis of Animal Behavior

    Författare :Tobias Palmér; Mathematical Imaging Group; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Datorseende; bildanalys; djurbeteende; neurofysiologi; tillämpningar; refraktion; Computer vision; animal tracking; behavioral analysis; refractions; underwater images; relative pose;

    Sammanfattning : The behavior of animals is commonly studied in medicine and biology. There is a large variation in what animals are studied, in experimental paradigms and purpose.However, many studies on animal behavior have at least one thing in common - it typically involves measuring or studying the kinematics of the animal.

  7. 5. Wind Turbine Drive Train System Dynamics ; Multibody Dynamic Modelling and Global Sensitivity Analysis

    Författare :Saeed Asadi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Global sensitivity analysis; Model validation; Multibody dynamics system mod-elling; Gearbox modelling; Kinematic constraints; Bearing defects detection; Wind turbine drive train dynamics; Floating reference frame;

    Sammanfattning : To facilitate the design and production of highly efficient and reliable wind turbine drive trains, this thesis deals with the mathematical modelling and analysis of drive train system dynamics. The drive train is considered as the subsystem of the wind turbine that transfers mechanical power from the rotor hub to the generator, and thereby plays an important role in the system dynamics and the efficiency of wind turbine operation.
