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...

Notes on Some Remedies. XVI. Arsenicals in Non-Syphilitic Diseases

1. Anthrax.?Anti-anthrax serum is an effective remedy in this condition, but when this is not available, full doses of NAB should be administered and repeated in a day or two if there is no response as shown by abatement of the local oedema. Arsenic may also be given as supplementary to serum, indeed such a combination appears to give better results and is desirable in severe cases, especially ...

-Monetary policy operates in a different environment than it did a decade ago. Financial market innovations have eroded the distinctions among monetary assets, making the definition of money increasingly arbitrary. Deregulation of interest rates and banking activity is changing the behavior of the monetary aggregates, as banks pay interest on monetary assets and nonbanks offer monetary-like ass...

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...
