Improvement of distance protection algorithms based on phasor measurements [PDF]

E3S Web of Conferences, 2023
Distance protection of overhead lines is widely used and is continually being improved. However, the distance protection cannot work stably and is blocked in several electromechanical transients. Additionally, a non-linear arc can affect the stability of

Improved Acoustic Thermometry for Long-Distance Temperature Measurements

Sensors, 2023
Accurate measurements of long distances (in the order of tens of meters or more) are necessary in manufacturing processes of large structures, as, for example, in the aerospace industry.

Uncertainty in Measurements of Distance [PDF]

, 2002
Ng and van Dam have argued that quantum theory and general relativity give a lower bound of L^{1/3} L_P^{2/3} on the uncertainty of any distance, where L is the distance to be measured and L_P is the Planck length.

On Pulsar Distance Measurements and their Uncertainties [PDF]

, 2012
Accurate distances to pulsars can be used for a variety of studies of the Galaxy and its electron content. However, most distance measures to pulsars have been derived from the absorption (or lack thereof) of pulsar emission by Galactic HI gas, which ...

Performance of an Ultrasonic Ranging Sensor in Apple Tree Canopies

Sensors, 2011
Electronic canopy characterization is an important issue in tree crop management. Ultrasonic and optical sensors are the most used for this purpose. The objective of this work was to assess the performance of an ultrasonic sensor under laboratory and ...

Direct Distance Measurements to Superluminal Radio Sources [PDF]

, 2000
We present a new technique for directly measuring the distances to superluminal radio sources. By comparing the observed proper motions of components in a parsec scale radio jet to their measured Doppler factors, we can deduce the distance to the radio ...

A vectorial tree distance measure [PDF]

Scientific Reports, 2021
Abstract A vectorial distance measure for trees is presented. Given two trees, we define a Tree-Alignment (T-Alignment). We T-align the trees from their centers outwards, starting from the root-branches, to make the next level as similar as possible.
