A novel method using particle swarm optimisation (PSO) is proposed for optimising parameters of controllers a wind turbine (WT) with doubly fed induction generator (DFIG). The PSO algorithm employed in the parameter tuning to search optimal and achieve coordinated control multiple WT system. implementation controllers' described detail. In analysis, generic dynamic model DFIG its associated presented, small signal stability derived; based on this, an eigenvalue-based objective function...
The proposal of dispersion region can complete the HC model, explain anomalous diffusion in low-voltage region, guide microstructure design high-performance materials, and provide new insights into storage mechanism SIBs.
It is of great significance to design and innovate electrode materials with unique structures effectively optimize the electrochemical properties secondary battery. Herein, inspired by neuron networks, an ingenious synthesis proposed fabricate NiSe multidimensional micro-nano structures, followed in situ construction NiSe/NiO heterostructures via a temporary calcination. The major structure bulk synthesized solvothermal method 3-dimensional micron cluster spherical particles interwoven...
This study aimed to compare whether differences in lifestyle and dietary habits have an impact on hyperuricemia provide a reliable basis for the health management of citizens our city. A total 10,883 subjects who did not suffer from hyperuricemia, was anticipated this 2018. After 2 years follow-up, 7727 3156 suffered hyperuricemia. Dietary were collected by questionnaire. Multivariate logistic regression used identify risk factors For analysis amount change uric acid (UA) before after years,...
<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <?Pub Dtl=""?>In this paper, a novel nonlinear control design method for the wind turbine (WT) with doubly fed induction generator (DFIG) using differential geometry theory is proposed. The WT DFIG represented by third-order model where electromagnetic transients of stator are neglected. Then exactly linearized coordinate transformation in theory. Since relative degree equal to order original...
Aberrant Smad7 expression contributes to the invasion and metastasis of pancreatic cancer cells. However, potential mechanism underlying aberrant in human ductal adenocarcinoma (PDAC) remains largely unknown. Bioinformatic prediction programmes luciferase reporter assay were used identify microRNAs regulating Smad7. The association between miR-367 overall survival PDAC patients was evaluated by Kaplan–Meier analysis. effects on cells investigated both vitro vivo. We found that downregulated...
Abstract The Yb:Lu 2 O 3 precursor made up of spherical particles was synthesized through the co-precipitation method in water/ethanol solvent. 5 at% powder is cubic phase after calcination at 1100 °C for 4 h. also consists nanoparticles with average particle and grain sizes 96 49 nm, respectively. size pre-sintered ceramic sample 526 nm that by hot isostatic pressing grows to 612 nm. 1.0 mm-thick has an in-line transmittance 81.6% (theoretical value 82.2%) largest absorption cross-section...
In this paper, a new nonlinear decentralized disturbance attenuation excitation control for multi-machine power systems is proposed based on recursive design without linearization treatment. The controller improves system robustness to dynamic uncertainties and also attenuates bounded exogenous disturbances the in sense of L/sub 2/-gain. Computer test results 6-machine show clearly that strategy can enhance transient stability more effectively than other controllers.
Spectroscopic properties of as-grown and γ-irradiated undoped Bi-doped α-BBO (BaB2O4) single crystals were investigated. Bi2+ color centers in Bi:α-BBO investigated to be nonluminescent the near-infrared (NIR) region. Broadband NIR luminescence at 1139 nm with a FWHM 108 decay time 526 μs was realized crystal through γ irradiation. Bi+ attributed responsible for emission, which can bleached by thermal annealing. The involved physical processes during courses irradiation heat annealing...
Objective Obesity, hypertension and diabetes are high prevalent that often associated with poor outcomes. They have become major global health concern. Little research has been done on the impact of lymphocyte-to-monocyte ratio (LMR) outcomes in these patients. Thus, we aimed to explore association between LMR all-cause mortality obese hypertensive patients without diabetes. Methods The researchers analyzed data from National Health Nutrition Examination Survey (2001-2018), which included...
The composite load model with an induction motor in parallel a static has been studied and applied analysis of dynamics power systems for long time. However, the parameters from field tests are still very limited. Based on theoretical results identifiability estimation methodology that have achieved previous work, project modelling based measurements is described. Eight sets equipment were installed HeNan Electric Power Grid (HNEPG) Corporation, recorded dynamic index proposed to evaluate...
<title>Abstract</title> Practical engineering dynamical analyses suffer from time-variant epistemic uncertainty variables. Precise description of uncertainties with only limited samples is a challenge to the safe and reliable assessment structures. Based on interval process theory, systematic study modeling quantities stationary characteristics under condition conducted. Firstly, by combining B-spline function convolution novel spline convolution-based kernel (SCK) method developed for...
