in this study, physical vapor deposition (pvd) ti-cr-n coatings were deposited at two different temperatures100 and 400ºc on hardened and tempered tool steel substrates. the influence of the applied deposition temperature on the physical and mechanical properties of coatings such as roughness, thickness, phase composition, hardness and young’s modulus were evaluated. phase compositions were stu...

The emerging network virtualization technique is considered as a promising technology that enables the deployment of multiple virtual networks over a single physical network. These virtual networks are allowed to share the set of available resources in order to provide different services to their intended users. While several previous studies have focused on wired network virtualization, the fi...

The accuracy of actions is swiftly determined through specific monitoring brain systems. Event-related potential (ERP) studies have shown that error commission is associated with the generation of the error-related negativity (ERN/Ne), while correct actions with the correct-related negativity (CRN). Although the exact functional meaning of the ERN/Ne (and CRN) component remains debated, some au...

CrN layers, 0.5 mm thick, were grown on MgO~001! at Ts5570– 775 °C by ultrahigh vacuum magnetically unbalanced magnetron sputter deposition in pure N2 discharges at 20 mTorr. Layers grown at Ts<700 °C are stoichiometric single crystals exhibiting cube-on-cube epitaxy: (001)CrNuu(001)MgO with @100#CrNuu@100#MgO . At higher temperatures, N2 desorption during deposition results in understoichiomet...

In order to increase channel usage efficiency, unlicensed users within a Cognitive Radio Network (CRN) are permitted utilize channels that not currently occupied by licensed users. However, ensuring communication between in CRN remains challenge. To overcome this issue, variety of hopping protocols have been developed. Time-invariant vulnerable attacks, so several resistant jamming attacks prop...

Cognitive radio network (CRN) enables unlicensed users (or secondary users, SUs) to sense for and opportunistically operate in underutilized licensed channels, which are owned by the licensed users (or primary users, PUs). Cognitive radio network (CRN) has been regarded as the next-generation wireless network centred on the application of artificial intelligence, which helps the SUs to learn ab...

The test results show that the fast Fourier process with multiple time superposition and a dimension length of 40 is most beneficial to accuracy model. loss curve value convolutional recurrent network model (CRN) much lower than other three models. music tone recognition learns better. rate recall CRN are highest, rates four indicators 94.6%, 92.4%, 93.5%, 92.5%, were 93.2%, 94.9%, 95.2%, 88.6%...

Microphone array-based sound source localization (SSL) is widely used in a variety of occasions such as video conferencing, robotic hearing, speech enhancement, recognition and so on. The traditional SSL methods cannot achieve satisfactory performance adverse noisy reverberant environments. In order to improve performance, novel algorithm using convolutional residual network (CRN) proposed this...

Background: There are reports indicating that among the others, hypoxia is one of the testes threatening factors, which may occur intentionally or accidentally. Hypoxia could be created secondarily after some pathological conditions such as anemia. In this study we aimed to investigate the crocin protective effect on the testes parameters in the animals that were exposed against phenyl hydrazin...
