Gradient nanostructure (GNS) has drawn great attention, owing to the unique deformation and properties that are superior with uniform scale. GNS is commonly fabricated via surface plastic small tips (of balls or shots) so as produce high refine coarse grains, but unfortunately it suffers from deterioration of quality which hard guarantee reliable service. Although there mirror-finishing techniq...

Seaweed draws a lot of attention for its vital role in aquaculture as it contains beneficial biological compounds that undoubtedly might help the development this field. The current study sheds light on potential efficiency dietary supplements Grateloupia acuminata and G. doryphore (Halymeniaceae) nanoparticles (GNS) at different levels with bionanocomposite cellulose acetate membranes (CA/bio-...

The Internet of Things (IoT) is playing an increasingly vital role in multiple industries and our everyday life. A pressing practical problem IoT devices (IoT-Ds) their explosive growth connectivity which leads to large energy consumption. One the most promising solutions achieve a sustainable green network unmanned aerial vehicle (UAV) enabled wireless power transfer (WPT) due its flexibility,...

In this article, we propose a framework for energy efficient trajectory design of an unmanned aerial vehicle (UAV)-based portable access point (PAP) deployed to serve set ground nodes (GNs). addition the PAP and GNs, system consists intelligent reflecting surfaces (IRSs) mounted on man-made structures increase number bits transmitted per Joule consumed measured as global efficiency (GEE). The G...

Unmanned Aerial Vehicles (UAVs) combined with Intelligent Reflective Surfaces (IRSs) represent a cutting-edge technology for improving the channel capacity of wireless communications, by capitalizing on UAVs’ 3D mobility coupled IRSs’ smart radio capabilities. This work envisions scenario in which swarm UAVs equipped IRSs serves multiple Internet Things (IoT) Ground Nodes (GNs) concurrently tra...

We introduce new definitions of states and of representations of covariance systems. The GNS-construction is generalized to this context. It associates a representation with each state of the covariance system. Next, states are extended to states of an appropriate covariance algebra. Two applications are given. We describe a nonrelativistic quantum particle, and we give a simple description of ...

On one-dimensional two-way infinite lattice system, a property of stationary (space-) translationally invariant states with nonvanishing current expectations are investigated. We consider GNS representation with respect to such a state, on which we have a group of space-time translation unitary operators. We show, by applying Goldstone-theoremlike argument, that spectrum of the unitary operator...

The fabrication of packaged, flexible, and planar fractional-order capacitors (FOCs) using copper foil electrodes thin films PVDF polymer nanocomposite dielectric is presented in this paper. An extensive comparison FOC properties made by two separate conductive fillers, i.e., graphene nanosheets (GNS) reduced oxide (rGO). Similar observed at a particular filler loading both types FOCs; however,...
