In the literature adaptive Fourier decomposition is abbreviated as AFD that addresses adaptive rational approximation, or alternatively adaptive Takenaka-Malmquist system approximation. The AFD type approximations may be characterized as adaptive approximations by linear combinations of parameterized Szegö and higher order Szegö kernels. This note proposes two kinds of such analytic approximati...

Food quality is a dominating factor influencing public health and affecting people, irrespective of age, race, gender, income, has raised concerns worldwide. It known to all that food influenced by many factors, such as climate change, harvesting, processing, drying, packaging. To be specific, with increasing temperatures atmospheric carbon dioxide levels, results in yield losses the reduction ...
