The parameters are the velocity of the foot element relative to water (Ur), the acceleration of the foot element relative to water (ar) and two angles α and β that represent the orientation of the foot element relative to the flow (Fig. 1).
Figure 5 shows the root mean square of speed relative to water calculated for foot element 1 (most proximal) and 6 (most distal).
To determine the propulsive force spent holding vertical position near the bottom the model uses four kinematic parameters for each foot element over the duration of the paddling cycle.
Thus, sirenomelia used to be classified as sympus dipus or symmelia if the two feet were present, sympus monopus or uromelia when only one foot was discernible, and sympus apus or sirenomelia when there was no evidence of any distal foot element (Saint-Hilaire, 1836; Forster, 1865) (Figs 1, 2).
The paper of Kim et al., published in 2008 in IEEE Transactions on Robotics, for example, grounds its roots in the scientific evidence published in Nature by Autumn et al. There, the authors performed the first direct measurements of the attraction force between surfaces and gecko structural feet elements, called setae, through a micro-electromechanical system.
"In the rain, bad weather, footing, or elements of precipitation, he can pierce a defense".
Christian Lacroix also seemed light on his feet, blending elements of flamenco with Spanish court colors in a lucid and original take on modern dressing.
Google purported to have huge amounts of quantitative information about its employees' work habits, and, although the campus would cover 1.1 million square feet, its elements were linked for fast, productive interaction.
The more sound, the more the lights flash on the 60 foot hanging element and the more the glass curtain wall flaps on the 18-video-monitor display, commenting on the never resolved debate about the "Windy City" moniker being based on the wind here or the hot air from Chicago politicians lobbying for the Colombian Exposition.
The blade-element approach is based on dividing the foot into smaller elements and calculating the drag and acceleration reaction forces for each element separately.
