A cognitive radio system needs accurate knowledge of the radio spectrum it operates in.Blind modulation recognition techniques have been proposed to discriminate between single-copyright and multicarrier modulations and to estimate their Round End Cap parameters.Some powerful techniques use autocorrelation- and cyclic autocorrelation-based features

Single-photon detectors, with their exceptional sensitivity, provide a reliable means for single-photon-level detection, demonstrating significant advantages in detecting weak signals in complex environments compared to traditional detectors.With the continuous advancement in semiconductor manufacturing technology, single-photon detectors based on

In this study the author specifically summarises Czech research on nobility in relation to the Habsburg Monarchy during the 19th Century.She demonstrates that the nobility did not comprise a monolithic, internally undifferentiated unit, because its lifestyle was still regulated by the specific provisions of the aristocratic hierarchy, which did not

A miniature fiber-optic dosimeter (FOD) system was fabricated using a plastic scintillating fiber, a plastic optical fiber, and a multi-pixel photon counter NEFF B47FS34H0B Built In Slide to measure real-time entrance surface dose (ESD) during radiation diagnosis.Under varying exposure parameters of a digital radiography (DR) system, we measured th
