1. 6. Computer Manikins in Evaluation of Manual Assembly Tasks

   Författare :Dan Lämkull; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; computer manikin software; virtual ergonomics; manikin appearance; digital human modelling; ergonomics evaluation; posture wizard; working posture;

   Sammanfattning : Digital human modelling (DHM) tools have been introduced in industry to facilitate a faster and more cost efficient design process. The research in this thesis is directed towards the DHM-tool-users’ needs and the objective is to identify difficulties and shortcomings, and identify requirements for improving the output of DHM-simulations.

3. 7. Human Postures and Movements analysed through Constrained Optimization

   Författare :Robert Pettersson; Anders Eriksson; Elena Gutierrez-Farewik; Hans Berg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multibody system; optimal control; trajectory optimization; long jump; posture; Other engineering mechanics; Övrig teknisk mekanik;

   Sammanfattning : Constrained optimization is used to derive human postures and movements. In the first study a static 3D model with 30 muscle groups is used to analyse postures. The activation levels of these muscles are minimized in order to represent the individual's choice of posture. LÄS MER

4. 8. Mobility, Sitting Posture and Reaching Movements in Children with Myelomeningocele

   Författare :Simone Norrlin; Lennart von Wendt; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; myelomeningocele; PEDI; mobility; sitting posture; reaching; motor adaptation; Pediatrik; Paediatric medicine; Pediatrisk medicin; pediatrik; Pediatrics;

   Sammanfattning : Children with myelomeningocele (MMC) usually have problems with daily life activities, but the background to their problems is not altogether obvious. An understanding of the possible causes of activity problems is a prerequisite for the effectiveness of physical therapy. LÄS MER

5. 9. Simulation of Human Movements through Optimization

   Författare :Robert Pettersson; Anders Eriksson; Elena Gutierrez-Farewik; Arne Nordmark; Anders Klarbring; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multibody system; human movements; optimal control; trajectory optimization; long jump; posture; rowing; somersault;

   Sammanfattning : Optimization has been used to simulate human neural control and resulting movement patterns. The short term aim was to develop the methodology required for solving the movement optimization problem often arising when modelling human movements. LÄS MER

7. 10. Human Vehicle Interaction Drivers’ Body and Visual Behaviour and Tools and Process for Analysis

   Författare :Lars Hanson; Ergonomi och aerosolteknologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Working process; Vision; Safety; Reach; Posture; Neural network; Fuzzy logic; Ergonomics; Driver behaviour; Documentation; Digital human modelling; Comfort; Button location; Car interior; Technology of other products; Produktteknik allmän ;

   Sammanfattning : Vehicle design is characterized by a high number of compromises. The special role of human factors in the process is to ensure that the compromises do not occur at the expense of the driver and passengers. LÄS MER
