Effect of head-neck posture on human discomfort during whole-body vibration

Effect of head-neck posture on human discomfort during whole-body vibration." MS (Master of Science) thesis, ii ACKNOWLEDGEMENTS I would like to acknowledge the people in the 3D Bio-Motion research lab at the Center for Computer Aided Design for their help and support with this thesis project. I would like to thank Sultan Sultan and Ting Xia for their help with the lab setup and preparation. I also express my gratitude to John Meusch and Rosalind Smith for their assistance with the motion capture and data analysis utilized in the 3D Bio-Motion research lab. Finally, I would like to give a special thank you to Salam Rahmatalla for providing his expertise and insights into human dynamics and human discomfort.
