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...

Fibroadenoma of 5 cm or more is called as giant fibroadenoma. Cosmesis an important consideration while making breast incisions, especially in young adults. In our case series 15 girls age group 18-30 years having fibroadenoma were considered for the study and underwent Swiss roll method excision. 3 4 incisions made ≤6 >6 size respectively. Post-operative scars cosmetic results documented. s...

A L-estimate will be established for cosine series, considering the generalized Fomin-class Fφ, where φ is a function more general than the power function

In this note, using the multisection series method, we establish the formulas for various power sums of sine or cosine functions.

In many applications, data takes the form of a continuous stream rather than a persistent data set. Data stream processing is generally an on-line, one-pass process and is required to be time and space efficient too. In this paper, we develop a framework for estimating join size over the data streams based on the discrete cosine transform (DCT). The DCT generally can provide concise and accurat...
