Some memristors with metal/insulator/metal (MIM) structure have exhibited random telegraph noise (RTN) current signals, which makes them ideal to build true number generators (TRNG) for advanced data encryption. However, there is still no clear guide on how essential manufacturing parameters like materials selection, thicknesses, deposition methods, and device lateral size can influence the qua...

the method expressed by salem and ravat. (2003) for depth estimation of magnetic sources is used on gravity anomalies for the first time. the depth of some rectangular prisms as synthetic models are estimated through the method. the gravity effect of these models is also considered with a relatively high value of random noise. a field example is also included and the depth of the main anomaly h...

The attenuation of coherent and random noise still poses technical challenges in seismic data processing, especially in onshore environments. Multichannel Singular Spectrum Analysis (MSSA) is an existing and effective technique for random-noise reduction. By incorporating a randomizing operator into MSSA, this modification creates a new and powerful filtering method that can attenuate both cohe...

Abstract: Background:  Many parameters effect on the noise exposure of bus drivers, which can be noted the bus type, where the engine, fuel type, age of buses and speed. The object of this study is the neural network modeling of noise exposure in Tehran bus transportation drivers. Material and Methods: Noise levels in 90 buses were sampled in three separate sub-sample including (1)30...

This paper evaluates the impact of removing random noise of radiance data using a spectral-spatial smoothing approach on data compression onboard a hyperspectral satellite. A datacube acquired using a Short Wave Infrared Full Spectrum Imager II for target detection application of hyperspectral data was tested. The impact was evaluated using both the statistical based measures and a remote sensi...

  Background and aims : Among all systems that each person may interact with in daily life public transportation systems may expose them to various risks. The noise exposure of drivers can cause accidents through developing hearing loss and stress and consequent impact on driver’s safety performance. The main objective of this study was to evaluate the relation between noise exposure and occupa...

Probabilistic-based methods have been used for designing noise tolerant circuits recently. In these methods, however, there is not any reliability mechanism that is essential for nanometer digital VLSI circuits. In this paper, we propose a novel method for designing reliable probabilistic-based logic gates. The advantage of the proposed method in comparison with previous probabilistic-based met...
