Abstract: The design and numerical modeling using Finite Element Analysis (FEA) of electric field strength in a programmable neural switch is carried out. The obtained model provided good approximation to the derived complex analytical solution, which is carried out by means of complex mathematical analysis employing SCHWARZ-CHRISTOFFEL transform. Effect of electrode separation and field spread...

Electric-field-induced resistive switching in metal-oxide interfaces has attracted extensive recent interest. While many agree that lattice defects play a key role, details of the physical processes are far from clear. There is debate, for example, regarding whether the electromigration of pre-existing point defects or the field-created larger lattice defects dominates the switch. We investigat...

The paper deals with condition monitoring of electric switch machines for railway points. The proposed detection system is based on off-line processing of armature current and voltage sampled as the machine operates a switch of railway tracks. The system, consisting of an algorithm tuned on a model of the machine as both the rails are driven towards their rest positions, allows detection of fau...

In this study, two different methods have been used in order to characterize lead-zirconate antiferroelectric thin film elaborated by a modified sol-gel process: First-Order Reversal Curves (FORC) measurements and impedance spectroscopy coupled hyperbolic law analysis. Approaches at low high applied electric fields allow concluding on the presence of weak residual ferroelectric behavior even if...

Since the equipment transmission parts of combination electric appliance in transformer substation are located in the shell, when an internal fault appears, the traditional charged test method only can preliminarily determine the defective position and types, but cannot directly shows the internal defects of the equipment. The Fuxin Company actively introduced X-ray CR imaging test technology a...

Recent years have witnessed intense interest in multifunctional surfaces that can be designed to switch between different functional states with various external stimuli including electric field, light, pH value, and mechanical strain. The present paper is aimed to explore whether and how a surface can be designed to switch between superhydrophobicity and superhydrophilicity by an applied strai...

Diffuse electron-beam ionized discharges break down into arc discharges under three different conditions: static (no discharge orE-beam), dynamic (discharge on) and pulsed (inductive) overvoltage at switch-off. Dynamic breakdown voltages are lower than static breakdown voltages but in normal operation the discharge "on" voltage is kept to a minimum. The maximum load voltage will only be present...

Certain niobium oxide (NbO , x ~ 2) materials are near insulating at room temperature fut undergo an "insulatorto-metal" transition near 800°C. A similar transition can be initiated at room temperature by applying an electric field. exceeding the "threshold" value, which depends on the oxygen concentration (x) of the NbOx. Metal-oxide threshold switch (MOTS) prototypes are obtained by applying ...
