We show in this article that fractionally integrated processes with Bloomfield (1973) exponential spectral disturbances can be well approximations to fractional models with AR disturbances. In fact, ...

The present paper deals with the approximation properties for exponential functions of general Durrmeyer type operators having the weights of Szász basis functions. Here we give explicit expressions ...

The beloved HP-35, one of the first scientific calculators able to “perform transcendental functions such as trigonometric, logarithmic and exponential functions” with an LED display just received an ...
