The COS method was introduced in Fang & Oosterlee (2008) and then applied to pricing a variety of stock options for continuous random variables. This paper adapts the Fourier-cosine series (COS) recover discrete probability mass functions. We approximate mixture compound distributions with cosine series. Enormous precision computational speed are qualities function estimates here obtained. also...

Conventional techniques for recovering deleted files often prove useless in recovering files in general and video files in particular, from downloads of the raw memory data from mobile telephones (containing NAND flash memory). Several factors that are relied upon conventionally do not occur in mobile telephones. This paper presents an approach for recovering deleted files in general and video ...
