In the current world lots of electronic data is generated in each and every field. These data
contains useful information to predict the future. Due to the huge in size, the manual …

Phase noise and frequency (in) stability both describe the fluctuation of stable periodic
signals from somewhat different standpoints. Frequency is unique compared to other …

We use frequency-comb-based optical two-way time-frequency transfer (O-TWTFT) to
measure the optical frequency ratio of state-of-the-art ytterbium and strontium optical atomic …

Abstract Received signals from Global Navigation Satellite Systems (GNSS) are nowadays
widely used by industry laboratories for ensuring metrological traceability for their respective …

We present a hardware computing module that calculates the frequency using timestamps
and the linear regression method. This solution is known as the frequency Ω-counter and its …

Optical fiber links are known as the most performing tools to transfer ultrastable frequency
reference signals. However, these signals are affected by phase noise up to bandwidths of …

This paper introduces the parabolic variance (PVAR), a wavelet variance similar to the Allan
variance (AVAR), based on the linear regression (LR) of phase data. The companion article …

Diabetes Mellitus is one of the growing fatal diseases all over the world. It leads to
complications that include heart disease, stroke, and nerve disease, kidney damage. So …

Alkali-metal magnetometers can provide a precise measurement of magnetic fields,
including their operation in Earth's ambient environments. In this thesis, we present …

The dual-mixer time-difference (DMTD) technique is used for precise low-noise time
comparisons. Its digital version (D-DMTD) was also already developed. The paper describes …
