Sequence Networks of Rotating Machines

Sequence Networks of Rotating Machines

A Y-connected synchronous generator, grounded through a neutral impedance, is designed to produce balanced internal phase voltages with only positive-sequence components. The generator's sequence networks include a source voltage that is exclusively in the positive-sequence network. The sequence components of line-to-ground voltages at the generator terminals illustrate this configuration.
Zero-sequence current induces a voltage drop across the generator's neutral impedance and other...

Sign Test for Matched Pairs

Sign Test for Matched Pairs

The sign test for matched pairs offers a robust method for comparing two paired samples, often for the effects of an intervention in one of them. This method is very useful in situations where the underlying distribution of the data is unknown. The test compares two related samples—often pre- and post-treatment measurements on the same subjects—to determine if there are significant differences in their median values.
To conduct the sign test, we first calculate the differences in value between...

Background:

Feature matching in visual tracking and geometric vision often relies on prior location information.
Existing methods can be computationally intensive and require significant image processing.

Purpose of the Study:

To dynamically utilize location priors for efficient feature matching.
To develop a novel search strategy that minimizes computational cost and image processing operations.

Main Methods:

Introduced the concept of dynamic sequential search (DSS).
Investigated optimal search order determination for DSS using multivariate Gaussian models.
Derived theoretical lower bounds for search region areas and conditions for optimality.
Developed a suboptimal search order algorithm with O(n3) complexity.

Main Results:

The proposed DSS method achieves global matching with fewer operations and lower computational cost.
The suboptimal search order algorithm offers a significant complexity reduction compared to state-of-the-art methods.
Validated effectiveness through statistical simulations and real-world monocular visual SLAM experiments.

Conclusions:

The dynamic sequential search approach provides superior performance in feature matching.
The method offers a computationally efficient alternative for visual SLAM and related applications.
Demonstrated significant improvements in both efficiency and accuracy over existing algorithms.
