The Koper model is a vector field in which the differential equations describe electrochemical oscillations appearing diffusion processes. This work focuses on understanding of slow dynamics stochastic perturbed by stable Lévy noise. We establish manifold for with noise and verify exponential tracking properties. also present two practical examples to demonstrate analytical results numerical si...

Titanium and its alloys have superior electrochemical properties compared to other alloy systems due the formation of a protective TiO2 film on metal surfaces. The ability generate oxide layer will depend upon type be used. aim this work was characterize corrosion behavior titanium Ti-CP2 Ti-6Al-2Sn-4Zr-2Mo, Ti-6Al-4V, Ti Beta-C. Samples were anodized in 1 M H2SO4 H3PO4 solutions with current d...

Carbohydrate antigen 19-9 (CA19-9) is an important biomarker for the early diagnosis and clinical monitoring of pancreatic cancer. Reliable, simple, and accurate methods for the detection of CA19-9 are still urgently needed. In this study, polythionine-Au composites (AuNPs@ PThi) were designed and prepared through one-pot reaction using HAuCl4 as the co-oxidant and raw material in thionine solu...

This paper presents an accurate technique for the characterization of intermodulation noise in wide band multi carrier power amplifiers. Band limited pseudo noise stimuli which are generated by using a computer controlled arbitrary waveform generator (AWG) connected to an I/Q modulator drive the input of the amplifier under test ( AUT ). The complex envelopes of the pseudo noises are measured u...
