Some trigonometrical series, XVII

A note on mixed boundary value problems involving triple trigonometrical series

This study was motivated by the two-dimensional hydrodynamic slamming problem of a steep wave hitting a vertical wall. The fundamental problem considers dual impact on the wall at the lower and upper region resembling the impact of a wave at the time of its breaking. The solution method results into a mixedboundary value problem that involves a triplet of trigonometrical series which, to the au...

Fragile watermarking using finite field trigonometrical transforms

Fragile digital watermarking has been applied for authentication and alteration detection in images. Utilizing the cosine and Hartley transforms over finite fields, a new transform domain fragile watermarking scheme is introduced. A watermark is embedded into a host image via a blockwise application of two-dimensional finite field cosine or Hartley transforms. Additionally, the considered finit...

Accommodation is most often seen in association with convergence, and it is well known that a variety of clues, particularly binocular fusion, drives convergence. Is there a monocular accommodation reflex, and if so, what is its stimulus? It is important to try to understand such a physiological error mechanism a widely distributed, unlearned, involuntary mechanism present in restricted monocul...

This study reports on the acoustic properties of the front vowel /i/ and the fronted back vowel /u/ in Standard Southern British English (SSBE). These two vowels are realized with very similar (and for some tokens overlapping) values of F2, so that F2 does not seem to be a reliable acoustic cue for the distinction between the two vowels. To test further possible cues to the English front-back c...
