Thus far, we have seen a number of different approaches to extracting information from data. This week, we will discuss the Fourier transform, and other related transformations that map data into a rather different space, while preserving the information. The Fourier transformation is usually presented as an operation that transforms data from the “time” or “space” domain, into “frequency” doma...

Radio occultations are commonly used to determine vertical profiles of ionospheric electron density from measurements frequency. “Frequency residuals” important intermediate data products in radio occultation experiments. Frequency residuals defined as the difference between observed and predicted values received frequency, where frequency includes all effects except refraction at target object...

statement of problem: surface disinfection is an important aspect of infection control in dentistry. a new generation of quaternary ammonium components (qacs) is gaining popularity as high-level disinfectants. two types of qac sprays, uniseptaquick and solarsept, are being widely used by iranian dentists. purpose: the aim of this study was to evaluate the clinical efficiency of unisepta quick a...
