Development of Synchronized Waveform Measurement and Its Application on Fault Detection

IEEE Transactions on Instrumentation and Measurement, 2023
Due to the massive installation of distributed renewables in distribution networks, the power signal may be changed extremely fast when a disturbance occurs, which leads to severe waveform distortion.

A note on the measurement of redundancy

Vegetatio, 1977
The present paper points out a simpler method for computing the redundancy coefficient proposed by Orloci (1975) using the inverse of the variance-covariance matrix. It is suggested that one should also examine the matrix of partial correlations between all pairs of species (with the rest held constant) since this gives additional information with ...

Redundancy and non-linearity measures for robot manipulators

Proceedings of the 1994 IEEE International Conference on Robotics and Automation, 2002
We investigate two new classes of performance measures. The first class quantifies the ability of a redundant manipulator to reconfigure itself while keeping the end-effector at a fixed position. The second measures the nonlinearity of the manipulator. We derive these measures using the differential-geometric formalism we introduced previously (1993). >

Redundancy and diversity measure inspired biometrics fusion

2010 IEEE Computer Society Conference on Computer Vision and Pattern Recognition - Workshops, 2010
In many identification problems, finding a duplicate using biometrics is very challenging task because of the size of the database and the errors related to the core biometrics engine. Fusion of different modes of biometric system can lead to improved recognition accuracy.

Measurement of redundancy in species collections

Vegetatio, 1975
The present paper describea a method, based on the covariance, which can partition the total variation in a species collection into two independent components. One of the components is specific to individual species, while the other is common between species.

Measures of Structural Redundancy in Reinforced Concrete Buildings. I: Redundancy Indices

Journal of Structural Engineering, 2004
A method based on nonlinear pushover analysis is proposed to quantify the deterministic and probabilistic effects of redundancy on the strength of structural systems. Two indices, the redundancy strength index and the redundancy variation index, are introduced to measure these effects.

Synergy, redundancy, and multivariate information measures: an experimentalist’s perspective

Journal of Computational Neuroscience, 2013
Information theory has long been used to quantify interactions between two variables. With the rise of complex systems research, multivariate information measures have been increasingly used to investigate interactions between groups of three or more variables, often with an emphasis on so called synergistic and redundant interactions.

Data redundancy in information and measurement systems

Energy Safety and Energy Economy, 2022
Data redundancy is a common approach to improve reliability of information and measurement systems. Design of information and measurement systems is an important step when the proper effect of data redundancy on accuracy of measurements needs to be established.

Measuring internal forces of redundant structures

Experimental Mechanics, 1985
Certain guidelines were formulated for conducting mechanical and electronic design, calibration and installation of steel or aluminum transducers, which may be utilized to monitor internal forces in selected elements of a redundant structure, directly and independently, without a need for analysis.

Application of Information Redundancy Measure To Image Segmentation

2019
In this paper, the problem of image segmentation quality is considered. The main idea is to find a quality criterion, which could have an extremum. The problem is viewed as selecting the best segmentation from a set of images generated by segmentation algorithm at different parameter values.
