A NEW DESIGN OF SINGLE SIDE BRUSHLESS DIRECT CURRENT LINEAR MOTOR

There are several simple variations to Mexican Hat Navigation. The first ones involves smoothing the path. This can be done by calculating the same path and then going back and applying an averaging filter to each point. Significant smoothing can be added by eliminating excursions where the path[r]

Physical activity is a key component of exploration and development. Poor motor proficiency, by limiting participation in physical and social activities, can therefore contribute to poor psychological and social development.
