TL;DR: In this article, the authors measured the apparent wake angle formed by the highest peaks, and observed the following three regimes: a small Froude number pattern, in which the divergent waves are not visible; standard wave patterns for which the maximum peaks occur on the outermost divergent wave; and a third regime in which they form a V-shape with an angle much less than the Kelvin angle.

TL;DR: In this article, the authors used geometrical arguments and analysis of an idealised mathematical model to identify features of spectrograms, concentrating on the effects of a finite-depth channel.

TL;DR: In this article, the authors use computer simulations of linear and nonlinear ship wave patterns and apply time-frequency analysis to generate spectrograms for an idealised ship and provide a possible explanation for a further discrepancy between the high-speed ferry spectrogram and linear theory by accounting for ship acceleration.

TL;DR: This approach provides opportunities to explore the nonlinear features of three-dimensional ship wave patterns, such as the shape of steep waves close to their limiting configuration, in a manner that has been possible in the two-dimensional analogue for some time.

TL;DR: Surfactant droplet evaporation experiments were performed on two commercial crop species, wheat and capsicum, along with two synthetic surfaces, up to a 90° incline, and mathematical models were developed to simulate the experiments.
