The Spectrum, developed by Retro Games Ltd., is a contemporary tribute to the iconic Sinclair ZX Spectrum, a microcomputer that left an indelible mark on the early 1980s. By blending the charm of ...

Abstract: In this tutorial article we review different multicarrier communication methods for the physical layer of cognitive radio systems. There, secondary users need to dynamically and reliably ...

What does a VNA measure? What can one do with the measured data? What devices are measured with a VNA? Most design engineers are familiar with tools of the trade such as voltmeters, oscilloscopes, ...

The analysis of electrical signals, otherwise known as signal analysis, is a fundamental challenge for virtually all electronic design engineers and scientists. While it provides valuable insight into ...

Refractive index (RI) sensors are of great interest for label-free optical biosensing. A tapered optical fiber (TOF) RI sensor with micron-sized waist diameters can dramatically enhance sensor ...

The combination of laser-induced breakdown spectroscopy and energy dispersive X-ray fluorescence spectroscopy in the coal quality analysis was reported formerly. But in the practical test of the ...

With the advance of sequencing technology, an increasing number of populations have been sequenced to study the histories of worldwide populations, including their divergence, admixtures, migration, ...
