AimThe specific questions in the theoretic part were:What is contained in the terms "balance and balance skill" and how can this skill be measured?The specific questions in the empirical part were:How does balance skill in different age categories of children correlate with biological and physiological parameters such as age, gender, body height, weight and level of physical activity?MethodsLiterature search based on books and scientific papers related to the questions posed above. Selection was made at libraries and on?line through "Pubmed". Specific search words were used.

This thesis is performed as a summarizing project for the mechanical engineering education at School of Engineering in Jönköping. All knowledge necessary to complete this thesis was gathered from previous courses and education.This project was to develop a new product for the company TR Equipment AB in Tranås. The new product is going to be based on an already existing product, TR 1700. TR 1700 is a bathtub equipped with a height adjustable function. This product is used in retirement homes and in the care of disabled people.

Along with the rapid expansion of wind power in Sweden during the last decades the competition about favorable areas has hardened. This among other reasons has caused the projectors to look into development of wind power in forests. There are several aspects regarding fatigue loads on the constructions that are severe in complex terrain, among which turbulence is one. The levels of turbulence which are accepted in order for the turbines to face a life length exceeding 20 years are regulated by the International Electrotechnical Commission, (IEC). In order to keep the turbulence below these levels there are three major steering tools to use: The ambient turbulence decreases with height and can therefore be regulated by the hub height of the turbines.
