objective(s): so far, extensive research has been conducted on the preparation and characterization of nano ceramics based on ca-si by sol- gel method and bioactivity was evaluated, but, a few researches have paid attention to the preparation of materials by mechanical activation (ma). the aim of this study was the preparation of akermanite nano powder by mechanical activation method and bioact...

Intrusion detection systems (IDS) are amongst the most important automated defense mechanisms in modern industry. It is guarding against many attack vectors, especially healthcare, where sensitive information (patient’s medical history, prescriptions, electronic health records, bills/debts, and other data points) open to compromise from adversaries. In big era, classical machine learning...

Reconfigurable intelligent surface (RIS) is a revolutionary technology for achieving high rate and large coverage in future wireless networks by smartly reflecting the signals with adjustable phase shifts. To design reflection beamforming, accurate individual channel state information required at RIS, which challenge task due to lack of signal processing ability passive mode. In this paper, we ...
