Plug-and-play graph reliability enhancement method for equipment state description under sparse information

The methods of the thermodynamic description of the nanoparticle state suggested by Gibbs, Shcherbakov, and Hill have been analyzed and the limits of the applicability of each considered method have been defined. The above methods allow one to describe the nanoparticle state over the whole range of their sizes from the lower limit, which corresponds to the size of the new phase nucleus, to the upper limit, which corresponds to the size of particles having the macrophase properties.

The procedure for describing all possible energy states of an alloy based on the concentration wave method proposed by Khachaturian is employed to describe all possible energy states of ordered A 2 BC alloy based on N-dimensional lattice. Within the framework of this method, a complete enumeration of the structures obtained by the superposition of N plane concentration waves with all possible wave vectors is carried out, provided that the given stoichiometry is preserved. For each such superposition, the order parameters on the first I coordination spheres are calculated, thereby determining the point in the I-dimensional order parameter space corresponding to the given structure. For the case of I = 2 it is shown that a complete enumeration of all structures generated by one plane concentration wave fills a non-convex figure in the space of two order parameters.

The method of description of the high-spin states, which was previously developed and applied for the states of this type in [Formula: see text]Pb, is generalized for the case of the states having more complex multiphonon structure. In this method, the harmonic approximation with the renormalized phonons is used in which the phonons themselves are determined within the nonlinear version of the model based on the random-phase approximation (RPA) and including both the RPA correlations and the beyond-RPA ones. The mean field and the residual interaction are derived within the framework of the self-consistent RPA from the energy-density functional of the Skyrme type. The method is applied for the analysis of the available experimental data in doubly magic [Formula: see text]Pb and [Formula: see text]Ca and in semi-magic [Formula: see text]Zr.

Prediction and programming of microemulsion phase behavior simulation

Condition monitoring has an important role in the enhancement of reliability of operation, reduction in major damages and improving operational efficiency of equipment’s and systems. Various non-destructive methods like oil analysis, wear and debris analysis, vibration analysis, temperature analysis and acoustic analysis is used in many industrial applications, renewable and non-renewable power plants, in engineering fields like fluid mechanics, concrete and infra structures in civil engineering, and reaming industries. In recent decades, acoustic monitoring techniques are emerging widely in vehicle industries, windmill, nuclear reactor, and thermal power plants for monitoring the condition of electrical or mechanical equipment’s. It has extended its application in diagnosis of health and fault condition of electrical machines due its low operating cost and continuous assessment for improving the life span, reliability, safety, performance, productivity and to decrease planned shutdowns. Acoustic signal processing is used in acoustic monitoring to monitor the healthy and faulty conditions of machines. The acoustic monitoring involves acoustic signal or data collection, signal processing, decision making, and fault diagnosis. In this paper, an overview of the advancements and developments in acoustic signal processing techniques for acoustic monitoring of electric machines are summarized.

Research on infrared image enhancement and segmentation of power equipment based on partial differential equation

Image detail enhancement is of wide application in image processing fields. In order to gain a better performance for detail enhancement, the computing cost is normally very large. Thus, it's unacceptable in real-time applications, such as video enhancement. In this paper, we propose a novel parallel framework for reliable real-time image detail enhancement based on recent proposed Gradient Domain Bilateral Filter (GDBF) which is realized on a multicore DSP platform: TMS320C6678. With the implement of parallel enhancement method, not only image base layer and detail layer are rapidly separated, but also the detail layer is further enhanced. Furthermore, the implementation of the parallel framework employs fix point programming instead of float point. With a bit-shift strategy for input image data, the computing precision is well satisfied. Experimental results show that our proposed framework outperform available state-of-the-art one, the processing time for 1080p image is less than 30ms. It is a good candidate for real-time image detail enhancement based on the multi-core DSP.

Lack of angiogenesis virtually excludes malignancy of a pulmonary nodule; assessment with quantitative contrast-enhanced CT (QECT) requires a reliable enhancement measurement technique. Diagnostic performance of different measurement methods in the distinction between malignant and benign nodules was evaluated. QECT (unenhanced scan and 4 post-contrast scans) was performed in 48 pulmonary nodules (12 malignant, 12 benign, 24 indeterminate). Nodule enhancement was the difference between the highest nodule density at any post-contrast scan and the unenhanced scan. Enhancement was determined with: A) the standard 2D method; B) a 3D method consisting of segmentation, removal of peripheral structures and density averaging. Enhancement curves were evaluated for their plausibility using a predefined set of criteria. Sensitivity and specificity were 100% and 33% for the 2D method resp. 92% and 55% for the 3D method using a threshold of 20 HU. One malignant nodule did not show significant enhancement with method B due to adjacent atelectasis which disappeared within the few minutes of the QECT examination. Better discrimination between benign and malignant lesions was achieved with a slightly higher threshold than proposed in the literature. Application of plausibility criteria to the enhancement curves rendered less plausibility faults with the 3D method. A new 3D method for analysis of QECT scans yielded less artefacts and better specificity in the discrimination between benign and malignant pulmonary nodules when using an appropriate enhancement threshold. Nevertheless, QECT results must be interpreted with care.

response to the problems that the existing studies have not fully considered the role of hydrogen storage in the longtime and large-scale new energy consumption and the existing energy systems containing hydrogen storage have not fully considered the severe weather conditions in the scheduling, a medium-term and long-term optimal scheduling for community integrated energy system with high proportion of renewable energy and multi-type energy storage is proposed. Firstly, a typical day selection method and a typical day sequence formation method are proposed based on the traditional multi-scenario method and the year-round weather conditions; secondly, a medium-term and long-term operation state description method for hydrogen energy storage considering the internal characteristics of typical days and the external arrangement sequence of typical days is proposed; again, the architecture of the integrated energy system containing hydrogen and thermal energy storage is introduced. Based on the internal characteristics of a typical day and the external linkage of a typical day, a medium-term and long-term optimal scheduling model and solution method for the community integrated energy system with high proportion of renewable energy and multi-type energy storage are proposed. Finally, the effectiveness and practicality of the proposed method are verified through the analysis of calculation cases.
