The Harmonic Pitching NACA 0018 Airfoil in Low Reynolds Number Flow
This study investigates the aerodynamic performance of a symmetric NACA 0018 airfoil under harmonic pitching motions at low Reynolds numbers, a regime characterized by the presence of laminar separation bubbles and their impact on aerodynamic forces. The

Hierarchical location method for harmonic sources in low-observability power distribution systems
To address the issue of harmonic source localization in low-observability power distribution systems, a hierarchical localization method based on physical network structure information is proposed.

Loudness matching of complex tones simulating sounds from electric trucks
With electric powertrains quickly advancing in the heavy vehicle sector, there is an increasing interest in the industry to find a general practice for evaluating tonal sounds. The challenge to set requirements is complex.

Ultra high energy gamma ray point sources and cosmic ray anisotropy [PDF]
The experimental set-up at the Baksan Air Shower Array, used to detect air showers above ~0.2xl0(^14)eV, is described. An estimation of the angular resolution using the cosmic ray shadow of the Sun and the Moon gives a value of ~2.5˚ which is consistent ...

The impedance of the harmonic plane in a dual three-phase permanent magnet synchronous motor (DTP-PMSM) is very low, meaning that even small harmonic voltages can induce significant harmonic currents, particularly at the fifth and seventh harmonic ...

On the number of nodal domains of spherical harmonics
It is well known that the \(n\)-th eigenfunction to one-dimensional Sturm-Liouville eigenvalue problems has exactly \(n - 1\) nodes, i.e. non-degenerate zeros. For higher dimensions, it is much more complicated to obtain general statements on the zeros of eigenfunctions.

Central L-values of elliptic curves, Tunnell's Theorem, and locally harmonic Maass forms [PDF]
In this talk, we will discuss a way to study the vanishing of central L-values of elliptic curves via locally harmonic Maass forms. In particular, we will discuss some combinatorial applications, such as an alternative formula for Tunnell's resolution of
