The Wigner distribution function applied to optical signals and systems
, 1978 In this paper the Wigner distribution function has been introduced for optical signals and systems. The Wigner distribution function of an optical signal appears to be in close resemblance to the ray concept in geometrical optics.

Complexity growth and the Krylov-Wigner function
Journal of High Energy PhysicsFor any state in a D-dimensional Hilbert space with a choice of basis, one can define a discrete version of the Wigner function — a quasi-probability distribution which represents the state on a discrete phase space.

Realisability of Wigner distributions
Electronics Letters, 1989 A time-frequency distribution C(t, omega ) is said to be WD-realisable if it is shown to be the Wigner distribution (WD) of a signal f(t). Conditions for this realisability are obtained using the FON basis vector representation of signals in L/sup 2/. >

New Journal of Physics, 2014 We present a new experimental approach to determine the Wigner distribution function of non-separable laser beams. A rotatable toroidal mirror is employed to focus an IR laser beam at a wavelength of $1064\;{\rm nm}$ .

Ambiguity Function and Wigner Distribution on the Sphere
, 2016 The ambiguity function and the Wigner distribution are fundamental tools in the time-frequency analysis. In this paper, we present an analog of the ambiguity function and the Wigner distribution for signals on the sphere.

Making sociotechnical doable: Cross‐disciplinary translations into engineering education
Journal of Engineering Education, Volume 115, Issue 4, October 2026.Abstract Background Engineering education research (EER) increasingly invokes the “sociotechnical,” yet the term travels across science and technology studies (STS), engineering studies, and EER in uneven ways. As EER faces shifting political and institutional pressures, understanding how concepts migrate across disciplinary boundaries offers insight ...

Kogia Records in Brazilian Equatorial and Southwestern Atlantic Oceans
Marine Mammal Science, Volume 42, Issue 4, October 2026.ABSTRACT The pygmy (Kogia breviceps) and dwarf (Kogia sima) sperm whales are cryptic cetaceans characterized by inconspicuous surfacing behavior, small group sizes, and deep‐diving habits, making visual detection particularly challenging. Here, we present the first broad‐scale passive acoustic monitoring (PAM) assessment of Kogia spp.
