To address the problems of poor model diagnosis and noise immunity caused by inconsistent distribution bearing fault features difficulty in feature extraction multi-condition environments, a method based on channel segmentation improved residual network is proposed. A mechanism designed for information highlighting, selecting one three-channel image as main operation channel, stacking it with s...

High-precision voltage sag cause identification is significant in solving the power quality problem. It challenging for traditional deep learning models to balance training complexity and recognition performance when processing high-dimensional staging data samples, which affects final effect. This paper proposes a method that fuses sparse auto-encoder Attention Unet. The model uses perform uns...

This paper presents the integration of an InGaAs avalanche photodiode (APD)with first amplification stage, comprised a low capacitance silicon N-channel dual-gate MOS-FET and associated passive components, in APD case. combined linear mode optical hybrid detector is used field terrestrial laser range finding. In this case, reduction input by 0.7 pF improvement signal-to-noise ratio (SNR) at low...

background: noise is one of the most important harmful agents in work environment. noise pollution in oil refinery industries is related to workers' health. this study aimed to determine the overall noise pollution of an oil refinery operation and its frequency analysis to determine the control plan for a vent noise in these industries. methods: this experimental study performed in control unit...

Advances in sub-micron technologies make low power consumption and delay a major concern for present day systems. These parameters play critical role the performance of most widely used wide fan-in-dynamic logic gates. fan-in dynamic gatesare employed designing high speed tag comparators which are blocks cache memory. The Stack-Scheme Clocked-Bleeder Domino (SS-CBD)tries to have an insight on 4...

objective(s) studies have described immunomedulatory effects of sun exposure and ultraviolet radiation on infectious and neoplastic diseases. here the effect of exposure to low potency radiation of sun on the course of leishmaniasis in mice was studied. materials and methods fifteen balb/c mice were exposed to suberythemogenic doses of sun (mean 180 mj/cm2/day of uvb) 2 months before and 4 mont...

background and objectives: brucellosis is an important health problem in developing countries and no vaccine is available for the prevention of infection in humans. because of clinically infectious diseases and their economic consequences in human and animals, designing a proper vaccine against brucella is desirable. in this study, we evaluated the immune responses induced by a designed recombi...

conclusions results indicated that the present vaccination program is insufficient for immunity against measles in this area. the general population immunity was lower than the necessary level for the elimination of measles. therefore, sero-epidemiological studies are necessary to organize national programs for control and elimination of measles. results overall, 821 (91.2%) of the studied popu...
