IEEE Transactions on Industrial Electronics, 2023 By measuring the open-circuit radial stray magnetic flux density (RSMFD) of three spatial points, a novel diagnostic method for the eccentricity of interior permanent magnetic motors (IPMSMs) in electric vehicles is proposed.

Computing the Eccentricity Distribution of Large Graphs
Algorithms, 2013 The eccentricity of a node in a graph is defined as the length of a longest shortest path starting at that node. The eccentricity distribution over all nodes is a relevant descriptive property of the graph, and its extreme values allow the derivation of ...

Eccentricity or spin precession? Distinguishing subdominant effects in gravitational-wave data [PDF]
Monthly notices of the Royal Astronomical Society, 2022 Eccentricity and spin precession are key observables in gravitational-wave astronomy, encoding precious information about the astrophysical formation of compact binaries together with fine details of the relativistic two-body problem.

Eccentricity Estimation for Five Binary Black Hole Mergers with Higher-order Gravitational-wave Modes [PDF]
Astrophysical Journal, 2022 The detection of orbital eccentricity for a binary black hole system via gravitational waves is a key signature to distinguish between the possible binary origins.

Signs of Eccentricity in Two Gravitational-wave Signals May Indicate a Subpopulation of Dynamically Assembled Binary Black Holes [PDF]
Astrophysical Journal Letters, 2021 The orbital eccentricity of a merging binary black hole leaves an imprint on the associated gravitational-wave signal that can reveal whether the binary formed in isolation or in a dynamical environment, such as the core of a dense star cluster.

GW190521: Orbital Eccentricity and Signatures of Dynamical Formation in a Binary Black Hole Merger Signal [PDF]
Astrophysical Journal, 2020 Pair-instability supernovae are thought to restrict the formation of black holes in the mass range ∼ 50 – 135 M ⊙ . However, black holes with masses within this “high mass gap” are expected to form as the remnants of binary black hole mergers.

Micromachines, 2023 In the realm of automatic wire-traction micromanipulation systems, the alignment of the central axis of the coil with the rotation axis of the rotary stage can be a challenge, which leads to the occurrence of eccentricity during rotation.

The eccentricity distribution of wide binaries and their individual measurements [PDF]
, 2021 Eccentricity of wide binaries is difficult to measure due to their long orbital periods. With Gaia’s high-precision astrometric measurements, eccentricity of a wide binary can be constrained by the angle between the separation vector and the relative ...

A Novelty of Hypergraph Clustering Model (HGCM) for Urban Scenario in VANET
IEEE Access, 2022 A vehicular ad hoc network is a dynamic and constantly changing topology that requires reliable clustering to prevent connection failure. A stable cluster head (CH) prevents packet delay (PD) and maintains high throughput in the network.
