Metamaterials have been attracting tremendous interests due to their exotic electromagnetic characteristics, such as sub-wavelength imaging and invisibility modbiv cloak.However, the appreciable loss arising from the inherent resonant nature of metamaterials plagues many of their engineering applications.In this paper, we derive the condition for a
In this paper, a joint method combining Hough transform and reassigned smoothed pseudo Wigner-Ville distribution (RSPWVD) is presented to detect time-varying interferences with crossed frequency for a Global Navigation Satellite System (GNSS) receiver with a galaxy s23 ultra otterbox defender case single antenna.The proposed method can prevent the
For manufacturing companies, reliable production planning and scheduling not only is the basis for efficient order processing but at the same time is an essential prerequisite for the integration and coordination of all participants along the entire supply chain.At the same time, the increasing delegation of planning activities to dynamic software
Since cyber-attacks are ever-increasing in number, intensity, and variety, a strong need for a global, standardized cyber-security knowledge database has emerged as a means to prevent and fight cybercrime.Attempts already exist in this regard.The Common Vulnerabilities and Exposures (CVE) list documents numerous reported software and hardware vulne
HIV infection has been acknowledged as a global public health concern since its emergence and it is clearly evident by the fact that the infection has accounted for the lives of 32 million people so far.It is important to consider that owing to the support from multiple sectors and a well-coordinated response owing to the assistance from the welfar
