Beyond Massive-MIMO: The Potential of Positioning with Large Intelligent\n Surfaces We then show that the CRLBs are dramatically increased for all three dimensions but decrease in the third-order of the surface-area. Moreover, with an infinitely large LIS the CRLB for the $z$-dimension with ...
Mass is a fundamental dimension in physics for understanding weight and inertia. 9 Unit A unit of mass in the metric system. The package weighs 2 kilograms. 9 Dimension A dimension representing the measurement of space. The dimension of length is crucial in calculating area and volume. 8 Unit...

The Dimension Theory in the class of frames was the base of many researches. Especially, the covering dimension, the quasi covering dimension, the small inductive dimension and the large inductive dimension for frames have been studied extensively (see (Banaschewski and Gilmour J. London Math. ...
摘要: We show the Julia set of has positive area and the action of on its Julia set is not ergodic; the Julia set of has Hausdorff dimension two but in the presence of an attracting periodic cycle its area is zero.DOI: 10.1090/S0002-9947-1987-0871679-3 被引量: 397 ...
a.Any one of the three physical or spatial properties of length, area, and volume. In geometry, a point is said to have zero dimension; a figure having only length, such as a line, has one dimension; a plane or surface, two dimensions; and a figure having volume, three dimensions. ...
(Physics) A physical property, such as mass, distance, time, or a combination thereof, regarded as a fundamental measure of a physical quantity Velocity has the dimension of distance divided by time. Aspect A side or surface facing in a particular direction The ventral aspect of the body. D...
area) then has dimensionsM/LT2; work or energy (force times distance) has dimensionsML2/T2; and power (energy per unit time) has dimensionsML2/T3. Additional fundamental quantities are also defined, such as electric charge and luminous intensity. The expression of any particular quantity in ...

In physics and mathematics, the dimension of a mathematical space (or object) is informally defined as the minimum number of coordinates needed to specify any point within it. Thus a line has a dimension of one (1D) because only one coordinate is needed to specify a point on it – for ...
