Abstract:
In the context of side-channel attacks, the Signal to Noise Ratio (SNR) is a widely used metric for characterizing the information leaked by a device when handling sensitive variables. In this paper, we derive the probability density function (p.d.f.) of the signal to noise ratio (SNR) for the byte value and Hamming Weight (HW) models, when the number of traces per class is large and the target SNR is small. These findings are subsequently employed to establish an SNR threshold, guaranteeing minimal occurrences of false positives. Then, these results are used to derive the theoretical number o

Beamforming (BF) technique in cooperative multiple input multiple output (MIMO) antenna arrays improves signal to noise ratio (SNR) of the intended user. The challenge is to design transmit beamforming vectors for every user while limiting the co-channel interference (CCI) from other users.

Abstract:
The early multi-point leakage source signals of urban gas pipeline are weak and can be easily affected by environmental noise and signal interference between adjacent sources, which causes large leakage positioning error. In this paper, an integrated signal processing method combining VMD, BSS and Relative entropy for multi-point pipeline leakage signal and source positioning is presented. Firstly, VMD and Relative entropy were employed to obtain effective IMF mode components and their features during the decomposition for pipeline leakage signal. Relative entropy was used to improve signal-to

Abstract:
USB keyboards are commonly used as computer input devices and inevitably generate electromagnetic (EM) leakage signals during their operation, which carry input information. However, due to the weak energy of a keyboard’s EM signal and the small amount of effective information, the received leakage signal is often characterized by a low signal-to-noise ratio (SNR). This low SNR affects the subsequent detection and restoration of the information. In order to solve this problem, this paper proposes a denoising method for USB keyboard EM leakage signals and designs a self-attentive denoising adve

An experimental study of the ratio of cumulants of acoustic signals of fluid leakage in a pipeline and interference is carried out. It is shown that the use of bandpass filtering increases the ratio of cumulants by orders of magnitude.
 The purpose of the article is to analyze the sensitivity of the cumulant method of detecting fluid leaks in a pipeline based on the statistical processing of the acoustic leakage signal and interference generated by the moving fluid flow. To analyze the possibilities of a cumulant leak detection method, it is necessary to have specific values of cumulants

Abstract:
Two types of 4H-SiC semiconductor detectors (D1 and D2) are realized based on ion implantation of 10B inside the aluminum metallic contact. The first detector shows a high leakage current after 10B implantation and low signal to noise ratio. However, improvements concerning the implantation parameters led to lower leakage current and thus to higher signal to noise ratio. Moreover such detectors show their stability under different thermal neutron fluxes showing the reproducible features of the pulse height spectra and same electrical behaviour before and after irradiation.

Abstract Accurate identification of leakage pressure signal is crucial for leakage detection and location of water supply pipelines. However, there is a lot of noise signals in the negative pressure waves generated during leakage accidents, making it difficult to identify leakage signals, and thus seriously affecting the accuracy of leakage detection. Therefore, in this study, we carried out leakage test of water transmission pipeline on our self-built test platform for transient flow with long-distance water transmission pipeline (pipeline length is 160 m, and diameter is 100 mm), and obtaine

Abstract:
Near-infrared fluorescence (NIRF) imaging involves the separation of weak fluorescence signals from backscattered excitation light. The measurement sensitivity of current NIRF imaging systems is limited by the excitation light leakage through rejection filters. In this contribution, the authors demonstrate that the excitation light leakage can be suppressed upon using appropriate filter combination and permutations. The excitation light leakage and measurement sensitivity were assessed and compared in this study by computing the transmission ratios of excitation to emission light collected and

High-precision magnetic field sensors are of increasing interest in non destructive testing (NDT). In particular GMR-sensors (giant magneto resistance) are qualified because of their high sensitivity, high signal-to-noise ratio and high spatial resolution. We performed magnetic flux leakage measurements of artificial cracks with a GMR-gradiometer and a 3-axes GMR-magnetometer. Cracks of a depth of 44 μm still could be detected with a sufficient high signal-to-noise ratio. A semi-analytic magnetic dipole model was used for swiftly predicting magnetic stray fields.

Frequency-response function calculation is an essential element in rotorcraft data analysis, especially for system identification, model validation and model analysis.

The local polynomial method is presented as an alternative to the methods that are based on segmenting and windowing the data and is particularly effective in reducing the leakage error.

Specifically, the sample cell is placed off-center in the ARR, where an excitation beam interacts with only one of the two (probe) beams counterpropagating in the ring.

Abstract Timeously detecting pipeline small leakages caused by corrosion, aging, and crack can critically impact structural safety. However, identifying small leaks is challenging and small leaks can gradually develop into significant leakage problems. Although the negative wave method is currently the most common approach used for pipeline leakage detection, it is limited by the working conditions, length, and diameter of the pipeline and cannot be employed to identify small leaks of less than 1 L per min in pipeline. Therefore, to address this problem, this paper established a technique base
