Neural ensemble dynamics underlying a long-term associative memory : Nature : Nature Research 2017-03-21T04:00:00Z Some idea of the nature of the work may be obtained from a mention of a few propositions: The medians of a triangle are concurrent in the centroid, or center of gravity of the triangle. The Teaching of Geometry 2011-10-12T02:00:52.133Z The couple is equal to the moment of the applied load W about an axis drawn through the centroid of the section p at right angles to the plane of bending.

Kinematics of Mechanisms from the Time of Watt In this case, the center of mass of the lamina corresponds to the centroid of the delineated region in the plane. Calculus, Volume 1 2016-03-30T00:00:00Z Green asterisks indicate the centroid position of each cell on day 1. Neural ensemble dynamics underlying a long-term associative memory : Nature : Nature Research 2017-03-21T04:00:00Z Above the centroid of compression there is nothing but a trifling amount of embedment of the stirrup. Some Mooted Questions in Reinforced Concrete Design American Society of Civil Engineers, Transactions, Paper No. 1169, Volume LXX, Dec. 1910 The vertical filament through the centroid of any cross-section becomes a cubical parabola, as shown in fig. Encyclopaedia Britannica, 11th Edition, Volume 9, Slice 2 "Ehud" to "Electroscope" 2011-01-29T03:00:23.777Z The symmetry principle can be a great help when finding centroids of regions that are symmetric. Calculus, Volume 1 2016-03-30T00:00:00Z Since we are only asked for the centroid of the region, rather than the mass or moments of the associated lamina, we know the density constant ρ cancels out of the calculations eventually.

Neural ensemble dynamics underlying a long-term associative memory : Nature : Nature Research 2017-03-21T04:00:00Z It would seem that the point where their full strength should be developed is rather at the neutral axis than at the centroid of compression stresses. Some Mooted Questions in Reinforced Concrete Design American Society of Civil Engineers, Transactions, Paper No. 1169, Volume LXX, Dec. 1910 Figure 6.71 We can use the symmetry principle to help find the centroid of a symmetric region. Calculus, Volume 1 2016-03-30T00:00:00Z By the symmetry principle, the centroid of R is the center of the circle. Calculus, Volume 1 2016-03-30T00:00:00Z We can adapt this approach to find centroids of more complex regions as well. Calculus, Volume 1 2016-03-30T00:00:00Z Scale bar, 10 μm. d, Cumulative histogram of distances between the centroids of all pairs of cells detected within the same imaging session, plotted with a logarithmic scale. Neural ensemble dynamics underlying a long-term associative memory : Nature : Nature Research 2017-03-21T04:00:00Z The centroid travels around the y-axis in a circular path of radius 4, so the centroid travels d = 8π units. Calculus, Volume 1 2016-03-30T00:00:00Z The symmetry principle says that if a region is symmetric with respect to a line, then the centroid of the region lies on the line.
