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...

Orthogonal Trajectories

Orthogonal Trajectories

Orthogonal trajectories describe the geometric relationship between two families of curves that intersect each other at right angles. One illustrative case involves a family of parabolas that open sideways along the x-axis. These curves share a common shape but differ by a scaling parameter, resulting in a set of curves that all pass through the origin and widen at different rates.Determining Orthogonal TrajectoriesTo identify the orthogonal trajectories for these parabolas, the first step...

Background:

Traditional camera networks require centralized processing and detailed environmental knowledge.
Ad-hoc distributed networks pose significant challenges for conventional surveillance and monitoring methods.
Existing approaches are often limited by the need for precise camera localization and environmental mapping.

Purpose of the Study:

To develop a coordinate-free topological representation for camera networks.
To enable robust, distributed algorithms for sensor network calibration and analysis.
To overcome the limitations of centralized processing in ad-hoc distributed camera networks.

Main Methods:

Introduction of the camera network complex (CN-complex) as a simplicial representation.
Development of a distributed algorithm for CN-complex construction using binary detection data.
Validation of the algorithm through two experimental setups.

Main Results:

The CN-complex accurately captures topological information of network visual coverage.
The representation eliminates the need for camera localization and environmental layout knowledge.
The algorithm successfully demonstrated the construction of the CN-complex using only binary detection information.

Conclusions:

The camera network complex offers a robust, decentralized solution for sensor network analysis.
This representation facilitates tasks such as identifying coverage holes, tracking agents, and finding homotopic paths.
The proposed method significantly advances the capabilities of distributed camera networks in surveillance and monitoring.
