Diagnostics of incipient faults for analog circuits is very important, yet very difficult. Traditionally, the soft faults can only be diagnosed under the occurrence of large variation of component parameters. In this paper, a novel approach for diagnosing incipient faults in analog circuits is proposed. First, a statistical property feature vector composed of range, mean, standard deviation, sk...

There is an increasing trend in the use of multi-objective evolutionary algorithms (MOEAs) to solve multi-objective optimization problems of the allocation of water resources. However, typically the outcome is a set of Pareto optimal solutions which make up a trade-off surface between the objective functions. For decision makers to choose a satisfactory alternative from a set of Pareto-optimal ...

In the era of very rapidly advancing technology like today, both internet and computerization have made various corporate agencies or investors start thinking about importance stock market in their capital division. Previously there were purchases by company's capital, such: gold, land, buildings, production machines, but at this time purchase shares should also to attract attention these are l...

Precise estimation of groundwater level (GWL) might be great importance for attaining sustainable development goals and integrated water resources management. Compared with alternative numerical models, soft computing methods are promising tools GWL prediction, which need more hydrogeological aquifer characteristics. The central aim this research is to explore the performance such well-accepted...

Nanopositioning technology is widely used in high-resolution applications. It often uses piezoelectric actuators due to their superior characteristics. However, exhibit a hysteresis phenomenon that limits positioning accuracy. To compensate for the effect, developing an accurate model of very important. This task challenging, requiring some considerations multivalued mapping loops and generaliz...

BACKGROUND Lack of a non-invasive diagnostic test contributes to the long delay between onset of symptoms and diagnosis of endometriosis. The aim of this study was to evaluate the combined performance of six potential plasma biomarkers in the diagnosis of endometriosis. METHODS This case-control study was conducted in 294 infertile women, consisting of 93 women with a normal pelvis and 201 wo...

The piano key weir (PKW) is a type of nonlinear control structure that can be used to increase unit discharge over linear overflow weir geometries, particularly when the weir footprint area is restricted To predict the outflow passing over a piano key weir, the discharge coefficient in the general equation of weir needs to be known. This paper presents the results of laboratory model testing of...

Abstract Qualitative analysis of water resources is one the most widely used topics in research today. Researchers use various methods parameters to achieve desired goals this field. This uses artificial intelligence (AI), learning machine (LM), data mining, and mathematical techniques simulate behavior estimate its parametric changes. The proposed model study was a Self-adaptive Extreme (SAELM...

The problem of low digging efficiency and mining imbalance due to outdated technology degree equipment intelligence has long existed in coal mine roadway excavation work. Lithology identification is the key roadheading equipment. Accurate lithology significantly affects automatic control roadheader cutting conditions. Completing process rock wall by a involved following steps: building tunnelin...
