Length measurement by means of a grid.
Experiments were performed which demonstrate some of the length-measuring characteristics of a grid consisting of two sets of parallel lines crossing each other at right angles. If lines of various shapes are repeatedly superimposed at random on such a grid, the mean number of intersections each of these lines makes with the lines of the grid is directly proportional to the length of the line. ...
متن کاملRatcheting up energy by means of measurement.
The destruction of quantum coherence can pump energy into a system. For our examples this is paradoxical because the destroyed correlations are ordinarily considered negligible. Mathematically the explanation is straightforward and physically one can identify the degrees of freedom supplying this energy. Nevertheless, the energy input can be calculated without specific reference to those degree...
متن کاملA New Framework for Increasing the Sustainability of Infrastructure Measurement of Smart Grid
Advanced Metering Infrastructure (AMI) is one of the most significant applications of the Smart Grid. It is used to measure, collect, and analyze data on power consumption. In the AMI network, the smart meters traffics are aggregated in the intermediate aggregators and forwarded to the Meter Data Management System (MDMS). The infrastructure used in this network should be reliable, real-time an...
متن کاملEstimating Measurement Precision by Means of Measurement Differences
When it is necessary to determine the precision of a certain instrument B, devoted to point position measurement for instance, but not necessarily, one way is to measure a certain number of points with B as well as with another instrument A, whose precision is known. Forming the differences between the B and A measurements, it is possible to calculate B precision by means of the dispersion of t...
متن کاملTransient Analysis of the Single-Conductor Overhead Lines Connected to Grid-Grounded Arrester under Direct Lightning by Means of GA
In this paper, genetic algorithm-based approach for transient analysis of single transmission line connected to arrester is proposed. In this approach, the lightning channel striking the overhead line is first represented by a current source and this source is truncated by a finite set of frequency harmonies in time domain. Norton equivalent circuit viewed across arrester is then computed by me...
