This paper describes a neural implementation of the resistive grid technique for route finding. The resistive grid, or Laplacian planning technique, is not plagued by local minima problems and guaranties and existing route to be found. The neural network comprises 2 layers. In the upper layer, lateral connections between neurons communicate information on the potentials of neighbouring nodes in...

Cu nano-particles (Cu-NPs) were embedded into the SiO2 layer of a Cu/SiO2/Pt structure to examine their influence on resistive switching characteristics. The device showed a reversible resistive switching behavior, which was due to the formation and rupture of a Cu-conducting filament with an electrochemical reaction. The Cu-NPs enhanced the local electric field within the SiO2 layer, which cau...

The resistive switching characteristics of the Cu/SiO x /Pt structure (control sample) exhibited a direct correlation to humidity. The H2O vapor formed the Cu oxide at the Cu/SiO x interface, and Cu ions were injected from the Cu oxide into the SiO x layer, thus improving the resistive switching. However, the control sample demonstrated substantial switching dispersion in a vaporless environmen...

Abstract Naturally occurring bitumen seeps migrating within the shallow subsurface contaminates soil and groundwater in communities eastern segment of Dahomey Basin southwestern Nigeria. Managing these contaminations require an understanding distribution to isolate contaminated regions avoid farming activities or drilling drinking water wells them. Several studies have assessed occurrence regio...

This paper describes and discusses the results of tests carried out on two families of PDM (Pulse Duration Modulation) AM transmitters. A variety of tests have been done using two tone techniques to evaluate the transmitters for linearity. Testing was carried out both into a 50 ohm resistive load and into a bandpass load to simulate the effects of a limited bandwidth antenna as proposed by USA ...

A method is developed for determing actual values of circuit elements in a damped sine wave (Lown waveform) defibrillator solely from measurements of the output, using two or more power resistors and a storage oscilloscope. If a defibrillator containing capacitance C, inductance L, and internal resistance RI, is discharged into increasing 5- to 100-ohm resistive loads R, it is shown for underda...

double layer zno/sno2 thin film resistive gas sensors were fabricated by successive pvd of those oxides onto porcelain substrates. the metallic contacts were provided by electron beam evaporation of platinum onto substrates prior to deposition of the gas sensitive layers. deposits were thermally annealed at different temperatures. it was shown that the activation energy of electrical conduction...

We report on a first implementation of a design which provides a significant reduction of AC losses in YB2Cu3O7−δ (YBCO) coated conductors (CCs) without mechanical twisting. The conductor is composed of two diffusively bonded silver clad commercial CCs with zigzag patterned filaments partially separated by a dielectric layer. We produced three fully bonded samples with 500 μm wide filaments usi...
